What is conjunctivitis?Conjunctivitis is redness and inflammation of the conjunctiva – the clear membranes covering the whites of the eyes and the inner part of the eyelids. To provide even greater transparency and choice, we are working on a number of other cookie-related enhancements.
Ear infections can cause serious ear pain, sleepless nights, missed work and school, and plenty of stress for parents. Diagnosis: The AAP recommendations apply more strict criteria for making the diagnosis of an ear infection. Follow up: the recommendations remind us that if you chose not to use antibiotics, you need to have a system in place for a follow-up visit or call in place 48-72 hours later.
Prevention: Breast feeding and avoidance of cigarette smoke are proven strategies to prevent ear infections in children.

The ear is a multifaceted organ that connects the central nervous system to the external head and neck.
The development of the external ear is a complex process that involves the merger of the 6 auricular hillocks. The 6 hillocks form from the first and second branchial arches and merge to form the structures of the auricle. As noted earlier, the ear is composed of external, middle (tympanic) (malleus, incus, and stapes), and inner (labyrinth) (semicircular canals, vestibule, cochlea) portions.
The auricle and external acoustic meatus (or external auditory canal) compose the external ear. The arterial supply of the auricle is composed of the posterior auricular artery, the anterior auricular branch of the superficial temporal artery, and the occipital artery, which also contributes.
The external acoustic meatus (external auditory canal) is formed by cartilage and bone (temporal). The arterial supply includes the posterior auricular artery, deep auricular branch of the maxillary artery, and superficial temporal artery. The primary functionality of the middle ear (tympanic cavity) is that of bony conduction of sound via transference of sound waves in the air collected by the auricle to the fluid of the inner ear. The tympanic cavity (middle ear) extends from the tympanic membrane to the oval window and contains the bony conduction elements of the malleus, incus, and stapes. The tympanic membrane (TM) is an oval, thin, semi-transparent membrane that separates the external and middle ear (tympanic cavity). Tympanic membrane (TM): pars flaccida (superior to insertion manubrium) and pars tensa (remainder of TM).
Air vibrations collected by the auricle are transferred to the mobile tympanic membrane, which then transmits the sound to the ossicles. The blood supply is derived from the stylomastoid branch of the posterior auricular, deep auricular and anterior tympanic branches from the maxillary artery. From the deep surface of the tympanic membrane to the oval window is a chain of movable bones, the ossicles. These bony elements serve to transmit and amplify sound waves from the air to the perilymph of the internal ear. The auditory tube (eustachian tube) is the communication between the middle ear and the nasopharynx. Important musculature in the middle ear (tympanic cavity) includes the stapedius muscle, which connects the neck of the stapes to the posterior tympanum. The horizontal portion of the facial nerve traverses through the tympanic cavity on its labyrinthine wall in a bony canal just superior to the footplate of the stapes. The chorda tympani, a recurrent branch of the facial nerve, is given off before the facial nerve exits the stylomastoid foramen. The tympanic plexus then supplies branches to the mucous membrane of the tympanic cavity (middle ear), the fenestra vestibuli and auditory tube, in addition to other regions.
The lesser petrosal nerve leaves the tympanic plexus by passing superiorly into the floor of the middle cranial fossa.
The arterial supply of the cavity includes the tympanic branch of the maxillary (tympanic membrane), stylomastoid branch of the posterior auricular (posterior cavity and mastoid), petrosal branch of the middle meningeal, branch of the ascending pharyngeal, tympanic branch of the internal carotid, and a branch from the artery of the pterygoid canal (follows the auditory tube).
The inner ear, also called the labyrinthine cavity, functions to conduct sound to the central nervous system (CNS) as well as to assist in balance (see the first image below). The labyrinthine cavity is essentially formed of the membranous labyrinth encased in the bony osseus labyrinth (see the following image). The osseus labyrinth consists of the cochlea, vestibule, and semicircular canals (see the image below). The vestibular apparatus is the membranous vestibule and is composed of the utricle and saccule.
The superior canal is positioned vertically; its lateral end is ampullated and communicates with the upper vestibule, whereas the opposite end joins the upper posterior canal at the crus commune, which opens into the upper medial vestibule.
Within the bony cochlea lies the membranous cochlea, wherein the energy of sound via pressure waves is transferred within the middle ear to the cochlear endolymph. The cochlea is split into 3 chambers (see the following image below), the scala vestibuli, the cochlear duct, and the scala tympani.
The scala vestibuli, or the superior chamber, is separated from cochlear duct by the vestibular membrane (Reissner membrane) and contains perilymph.
The cochlear duct, or the scala media, the central chamber, is well-defined by the vestibular membrane superiorly and the basilar membrane inferiorly. The scala tympani, or the inferior chamber, is separated from the cochlear duct (above) by the basilar membrane and contains perilymph. Once the sound wave has been conducted via the osseus tympanic cavity (middle ear), the energy is transmitted by the footplate of the stapes displacing the oval window medially into the vestibule in the region of the base of the cochlea. The basilar lamina, when uncoiled, has an apex and base; the apex is wider than the base (see the image below). Higher frequencies stimulate the base of the cochlea, whereas lower frequencies stimulate the apex. Congenital abnormalities of the ear are common and largely affect the shape of the auricle. Humid conditions and swimming in contaminated water can predispose patients to infections of the external ear, otitis externa. Acute and chronic inflammation of the middle ear lining, otitis media, can lead to severe swelling and subsequent necrosis and perforation of the tympanic membrane, allowing spontaneous drainage of fluid (usually pus). Bone formation around the ossicular chain of the middle ear can lead to poor mobility of the joints, specifically the stapes and oval window.
An additional etiology of hearing impairment in the middle ear is trauma; shearing forces can uncouple the ossicular chain, thus leading to disrupted conduction of sound.
Benign epidermoid tumors, cholesteatomas (see the image below), can occur in the middle ear and mastoid.
Meningitis can produce inner ear pathology and symptoms as a consequence of communication between the perilymph of the inner ear and cerebrospinal fluid. Meniere disease and Meniere syndrome are pathologic entities that are incurred as a result of an inflammatory response and endolymphatic accumulation in excess, endolymphatic hydrops.

Conjunctivitis is often caused by a virus or by a bacterial infection, called infective conjunctivitis, although allergies, toxic agents and underlying diseases can also be responsible. It is intended for general information purposes only and does not address individual circumstances.


For some children, ear infections can become a chronic problem leading to clinic visits, multiple courses of antibiotics, and sometimes a surgery for tube placement. These infections really hurt and don’t wait for antibiotics to start to work or make your child tough it out. When a confirmed ear infection is discovered in a child over 2 years of age who has no fever or no severe ear pain, they can be observed without antibiotics. If symptoms of the ear infection resolve in 2-3 days with use of pain medications and time, the ear infection is likely healing. If symptoms (on or off medications) are not better in 2-3 days, your child needs to be seen again either to start antibiotics or switch medications. Make sure your child is up-to-date on all vaccines but specifically ensure your child is up to date on Hib, Prevnar (pneumococcal vaccine) and their annual influenza Shot.
This structure as a whole can be thought of as 3 separate organs that work in a collective to coordinate certain functions, such as hearing and balance. The complexity inherent in this process creates many areas for abnormal growth and development to occur. The tragus, helical crus, and helix likely form from the first arch (first through third hillocks), which is referred to as the mandibular arch. The external ear functions to collect and amplify sound, which then gets transmitted to the middle ear.
The canal measures about 4 cm in length (from the tragus) to the tympanic membrane and is curved in an S shape. Venous drainage includes the external jugular from veins on the superficial aspect of the tympanic membrane and veins from the deep surface of the tympanic membrane draining to the transverse sinus and dural veins.
Sound waves transmitted to the tympanic membrane push it medially, the malleus pulls the incus laterally through its synovial joint, the incus then causes the footplate of the stapes to displace the oval window (the fenestra vestibuli), causing a pressure wave in the fluid of the inner ear. It enters the tympanic cavity (middle ear) after exiting a bony canal and passing medial to the neck of the malleus invested in the mucous membrane, then it emerges in the carotid wall. Auditory transduction, the conversion of acoustic (mechanical) energy to electrochemical energy, takes place within the labyrinthine cavity (see the second image below).
The osseus labyrinth is a series of bony cavities within the petrous temporal bone; the membranous labyrinth is the communicating membranous sacs and ducts housed within the osseus labyrinth. This directional change is sensed by the brain via the superior division of the vestibular nerve at the utricle and via the inferior division of the vestibular nerve to the saccule. The superior, posterior, and lateral semicircular canals sit behind and superior to the vestibule (see the following image). The posterior canal parallels the posterior petrous temporal bone; its lower end, the ampullated end, opens into the lower vestibule, whereas the upper end joins the crus commune.
The osseus cochlea is shaped like a snail shell, with 2.5 turns of a canal coiled around the central modiolus. The energy created within this liquid medium is converted to electrical energy that is transmitted to the CNS via the cochlear nerve. This chamber originates in the vicinity of the oval window (which communicates with the middle ear and the footplate of the stapes) and spirals toward the apex of the modiolus, the helicotrema, where it communicates with the scala tympani. In contrast to the scala vestibuli, the scala tympani commences at the apex of the modiolus, the helicotrema, and winds down to the round window (fenestra cochleae), which is covered by the secondary tympanic membrane. Fluid then flows within the scala vestibuli of the cochlea, transmitting pressure to the basilar membrane; eventually, the flow proceeds to the scala tympani, displacing the round window membrane back into the middle ear. Acoustic stimulation travels from the base to the apex, with higher frequency stimuli causing excitation at the base, low frequency at the apex. This nerve originates between the pons and medulla oblongata in the brain and passes into the petrous temporal bone through the internal acoustic meatus. Acquired entities can further be delineated into intrinsic processes, such as cancer, and extrinsic processes, such as trauma. They are often accompanied with abnormalities of the middle ear because the underlying development of both arise from similar structures. Small, central perforations often heal without significant sequela; however, marginal perforations that dona€™t heal can lead to growth of skin from the ear canal into the middle ear. Chronic inflammation can lead to irreversible scarring of the tympanic membrane, termed tympanosclerosis, leading to poor mobility of the tympanic membrane and poor sound conduction. This leads to discontinuity of the ossicular chain of the middle ear with the inner ear, creating progressive conductive hearing loss.
These traditionally form from acquired etiologies such as tympanic membrane perforations, with the skin healing into the middle ear and chronic auditory tube dysfunction.
Pregnant mothers can contract this virus, leading to destruction of the developing fetal cochlea and subsequent deafness. This endolymphatic hydrops and subsequent increased pressure leads to episodic hearing loss, tinnitus, severe vertigo, and a sense of fullness in the ear.
Patients traditionally experience repetitive episodes of vertigo incurred after changes in head position relative to gravity. Accessible and Informative Sectioned Images, Color-Coded Images, and Surface Models of the Ear.

It is not a substitute for professional medical advice, diagnosis or treatment and should not be relied on to make decisions about your health. While most children recover from ear infections in two or three days without any antibiotics, about 25% need help.
If pain is still present or symptoms not improved in 48 hours, promptly make a follow-up visit. Development begins at 3 weeks' gestation, with the formation of the otic disc from a thickening of ectoderm. The antihelix, antitragus, and lobule form from the second arch (fourth through sixth hillocks), also referred to as the hyoid arch. The asymmetric shape of the external auricle introduces delays in the path of sound that assist in sound localization. The mandibular condyle sits anterior to the bony portion of the external acoustic meatus (external auditory canal). The manubrium of the malleus is firmly attached to the medial tympanic membrane; where the manubrium draws the tympanic membrane medially, a concavity is formed. Contraction of the tensor veli palatini and the salpingopharyngeus outside of the tympanic cavity (middle ear) dilate and open the auditory tube (see the image below).
Contraction displaces the stapes posteriorly and functions to prevent loud noises from injuring the inner ear. Innervated by the mandibular branch of the trigeminal nerve, contraction of the tensor tympani displaces the malleus (and the tympanic membrane) medially, thus tensing the tympanic membrane and dampening sound vibration as well. The chorda tympani innervates the submandibular and sublingual salivary glands and the anterior two thirds of the tongue (carrying taste information). The membranous labyrinth is cushioned by the surrounding perilymph and contains the endolymph within its confines. The fenestra vestibuli or oval window is an opening in the lateral wall of the vestibule of the osseous (bony) labyrinth.
The utricle is closer in proximity to the semicircular canals, and the saccule is close to the cochlea.
Together, the otolithic organ organs of both ears are of prime importance in directional sensation. The lateral canal is directed horizontally, and its ampullated end opens to the upper and lateral vestibule, whereas the opposite end opens to the upper posterior vestibule.
This function is achieved via the cristae ampullaris, mechanoreceptors within the confines of the membranous ampullae. These hair cells have stereocilia branching outward into the gelatinous tectorial membrane (see the previous image). This perilymph flow within the cochlea leads to mobility of the hair cells of the spiral organ. The information transmitted by the hair cells within the spiral organ to the cell bodies, spiral ganglion, of the cochlear nerve. It is within the temporal bone that the nerve divides into superior and inferior vestibular nerves as well as a cochlear branch.
Large, nonhealing perforations decrease the surface area of the tympanic membrane, leading to impaired acoustic collection.
Chronic fluid and inflammation in the middle ear worsens hearing and can interfere with language skills, often seen in children with auditory tube dysfunction. Increasing endolymphatic pressure ruptures the lining of the membranous labyrinth, creating an avenue for mixture of endolymph and perilymph and subsequent permanent hearing loss. The pathologic mechanism is thought to be caused by dislodgement of the otoconia, "ear rocks," within the utricle. Hearing loss can also be spurred by prolonged sound exposure greater than 85 decibels (dB), such as that in industrial settings.

Incision made in the eardrumA small cut (incision) is made in the eardrum to allow fluid to drain.Fluid draining through the incisionFluid from the middle ear drains through the incision into the ear canal and is suctioned out by the doctor.
It’s easily spread through poor hand washing or by sharing an object (like a towel) with someone who has it. Never ignore professional medical advice in seeking treatment because of something you have read on the BootsWebMD Site. Ear infections can be caused by viruses or bacteria when excess fluid gets trapped behind the ear drum. It’s important that the doctor confirm an ear infection is present before antibiotics are prescribed.
Growth is largely complete by 20 week's gestation, and most abnormalities in ear development occur prior to the seventh week.
Facial nerve paralysis causes uninhibited movement of the stapes footplate, with sound transmission causing acuteness of hearing, which can then cause damage to the inner ear.
This muscle lies within the temporal bone in a plane along the superior aspect of the auditory tube. It articulates with the footplate of the stapes from the middle ear and opens into the fluid-filled inner ear. The orientation of the utricle is largely axial and registers acceleration in the horizontal plane. The endolymphatic flow changes within the substance of the semicircular canals are sensed by these mechanoreceptors, and this information is transmitted to the vestibular nerve. Its base is perforated for transmission of filaments of the cochlear division of the vestibulocochlear nerve (cranial nerve VIII).
The vestibular nerves carry information from the saccule, utricle, and ampullae by way of the vestibular (Scarpa) ganglion. Along with various lacerations and avulsions that can occur to any body part, blunt trauma can cause an auricular hematoma. Cholesteatomas are not malignant, but they become problematic, as they are locally destructive secondary to erosion and the dead debris that accumulates, and they can become a nidus for infection. The disease and syndrome are differentiated by idiopathic etiology (disease) versus excess endolymphatic accumulation secondary to increased production or decreased resorption (syndrome).
The mobilized otoconia, crystals made of calcium carbonate, migrate into the semicircular canals. Easily compare tier status for drugs in the same class when considering an alternative drug for your patient.
In this case, as a result of a build- up of pus in the middle ear, the eardrum has ruptured (perforated eardrum) causing a purulent discharge.
Ear tube placedThe temporary tube is inserted into the eardrum incision to prevent future fluid buildup. Children diagnosed with conjunctivitis may be asked to stay off school or nursery for a short period of time, although Public Health England says this is not necessary unless a child is unwell. The American Academy of Pediatrics (AAP) has released new guidelines to help doctors do a better job treating ear infections. If a clinician says to you, “It looks like an early ear infection” or “The ear drum is a little red” or “I think this may be an ear infection” chances are it does not meet criteria and should not be treated with antibiotics. This growing auricular complex forms ventrocaudally, near the base of the neck, but moves dorsocranially with the growth of the mandible and ultimately arrives at its final position, level with the eyes, around 32 weeks' gestation. The area of the tympanic membrane superior to the umbo is termed the pars flaccida; the remainder of the tympanic membrane is the pars tensa (see the image below).
Conversely, the saccule is oriented in a coronal plane and senses acceleration in a vertical plane. This ability to detect angular acceleration in 3 dimensions is critical for maintaining balance.
Sound information is transmitted through the spiral ganglion to the cochlear nerve from the cochlea.
Head reorientation relative to gravity induces movement of these crystals within the semicircular canal, inducing endolymphatic fluid displacement and the sensation of vertigo. Analgesic drugs may be given to relieve the pain whereas the infection is treated with antibiotic drugs. Allergic conjunctivitis (caused by seasonal pollens, animal dander, cosmetics and perfumes) and chemical conjunctivitis (from toxic chemicals or liquids, including bleach and furniture polish) are not contagious. Symptoms of ear infections include pain, fever, ear drainage, loss of appetite, difficulty hearing, difficultly sleeping, crankiness, and pulling on the ear. These recommendations also suggest ways to reduce ear infections, such as promoting breast feeding, keeping kids away from cigarette smoke, no bottle propping, and making sure they are properly vaccinated.
Ask your doctor if the ear drum is bulging and full of fluid. If no proof, antibiotics are probably not necessary.
The saccule is connected to the cochlear duct via the ductus reuniens and to the utricle by the utriculosaccular duct. This disorder can be diagnosed with the Dix-Hallpike maneuver, which reorients the head to align the posterior canal with gravitational forces, provoking the classic positional vertigo. The endolymphatic duct is a branch of the utriculosaccular duct and terminates as a dilated endolymphatic sac. Conjunctivitis is a common condition that is rarely serious and will not cause long-term eye or vision damage if promptly detected and treated.
The most important medicine you give your child when you first suspect an ear infection is one for pain. The endolymphatic duct and sac play an important role in the uptake and removal of endolymph.
Symptom: Lots of tearsInfective and allergic conjunctivitis are known for causing more tear production than usual.
Symptom: Itchy or burning eyesYou would know it if you felt it - that overwhelming itchy, burning, or gritty feeling in the eyes, which is typical of conjunctivitis. Symptom: Drainage from the eyesA clear, watery drainage is common with infective and allergic conjunctivitis. When the drainage is more greenish-yellow (and there’s a lot of it), this is more likely to be infective conjunctivitis.
Symptom: Crusty eyelidsIf you wake up with your eyes "stuck shut", this may be caused by the discharge that accumulates during sleep from infective conjunctivitis. Crusty eyelids are less common with viral conjunctivitis than with bacterial conjunctivitis. Symptom: Sensitivity to lightConjunctivitis can cause mild sensitivity to light (photophobia).
A child who has severe symptoms, such as changes in vision, photosensitivity or severe pain may have an infection that has spread beyond the conjunctiva and should receive urgent medical advice. Symptom: 'Something in the eye'You may notice an irritating feeling like something is stuck in your eye. Diagnosing conjunctivitisA doctor can usually diagnose conjunctivitis by its characteristic symptoms. In some cases, a swab of the discharge from the eye is sent to a lab for analysis to determine the cause. When conjunctivitis means something morePersistent conjunctivitis can be a sign of an underlying medical condition in the body. Often these are inflammatory diseases, such as rheumatoid arthritis and systemic lupus erythematosus (lupus). Conjunctivitis is also seen in Kawasaki disease (a rare disease associated with fever in infants and young children) and certain inflammatory bowel diseases, such as ulcerative colitis and Crohn’s disease. Treating conjunctivitisAntibiotics are not usually prescribed for infective conjunctivitis nowadays. If the symptoms are severe or persist then antibiotic eye drops or ointment may be recommended.
Allergic conjunctivitis should improve once the allergen is removed and can be treated with anti-allergy eye drops.
Chemical conjunctivitis requires prompt washing of the affected eye(s) for five minutes and immediate medical attention. Do likewise when removing discharge from the eyes by wiping from the inside to the outside of the eye area. How long am I contagious?Conjunctivitis is infectious from around the time symptoms appear until the time when the symptoms have resolved. Public Health England advises that it is not generally necessary to keep a child with conjunctivitis away from school or nursery. Preventing its spreadIf you or your child has infective conjunctivitis, avoid touching the eye area, and wash your hands frequently.
