Myringosclerosis rarely causes any symptoms. Tympanosclerosis, on the other hand, can cause significant hearing loss or chalky, white patches on the middle ear or tympanic membrane.
"Myringosclerosis" refers to a calcification only within the tympanic membrane and is usually less extensive than "intratympanic tympanosclerosis", which refers to any other location within the middle ear such as the ossicular chain, middle ear mucosa or, less frequently, the mastoid cavity.
The majority of tympanic membrane retractions do not cause any symptoms. Some cause hearing loss by restricting sound-induced vibrations of the eardrum. Permanent conductive hearing loss can be caused by erosion of the ossicles (hearing bones). Discharge from the ear often indicates that the retraction pocket has developed into a cholesteatoma.
The majority (98%) of patients with cholesteatoma have ear discharge or hearing loss or both in the affected ear.
Other more common conditions, such as otitis externa, may also present with these symptoms, but cholesteatoma is much more serious and should not be overlooked. If a patient presents to a doctor with ear discharge and hearing loss, the doctor should consider the patient to have cholesteatoma until the disease is definitely excluded.
Other less common symptoms (all less than 15%) of cholesteatoma may include: pain, balance disruption, tinnitus, ear ache, headaches and bleeding from the ear. There can also be facial nerve weakness.
Balance symptoms in the presence of a cholesteatoma raises the possibility that the cholesteatoma is eroding the balance organs, which form part of the inner ear.
On initial inspection, an ear canal full of discharge may be all that is visible. Until the doctor has cleaned the ear and inspected the entire tympanic membrane, cholesteatoma cannot be either confirmed or excluded.
Once the debris is cleared, cholesteatoma can give rise to a number of appearances. If there is significant inflammation, the tympanic membrane may be partially obscured by an aural polyp. If there is less inflammation, the cholesteatoma may present the appearance of 'semolina' discharging from a defect in the tympanic membrane. The posterior and superior parts of the tympanic membrane are most commonly affected. If the cholesteatoma has been dry, the cholesteatoma may present the appearance of 'wax over the attic'. The attic is just above the ear drum.
The patient may commonly also have clinical signs of conductive hearing loss. Less frequently, there may be signs of imbalance or facial weakness.
If untreated, a cholesteatoma can eat into the three small bones located in the middle ear (the malleus, incus and stapes, collectively called ossicles), which can result in nerve deterioration, deafness, imbalance and vertigo. It can also affect and erode, through the enzymes it produces, the thin bone structure that isolates the top of the ear from the brain, as well as lay the covering of the brain open to infection with serious complications (rarely even death due to brain abscess and septicemia).
Both the acquired as well as the congenital types of the disease can affect the facial nerve that extends from the brain to the face and passes through the inner and middle ear and leaves at the anterior tip of the mastoid bone, and then rises to the front of the ear and extends into the upper and lower face.
Tympanic membrane retraction describes a condition in which a part of the eardrum lies deeper within the ear than its normal position.
The eardrum comprises two parts, the pars tensa, which is the main part of the eardrum, and the pars flaccida, which is a smaller part of the eardrum located above the pars tensa. Either or both of these parts may become retracted. The retracted segment of eardrum is often known as a retraction pocket. The terms "atelectasis" or sometimes "adhesive otitis media" can be used to describe retraction of a large area of the pars tensa.
Tympanic membrane retraction is fairly common and has been observed in one quarter of a population of British school children. Retraction of both eardrums is less common than having a retraction in just one ear. It is more common in children with cleft palate. Tympanic membrane retraction also occurs in adults.
Attempts have been made to categorise the extent of tympanic membrane retraction though the validity of these classifications is limited.
Cholesteatoma is a destructive and expanding growth consisting of keratinizing squamous epithelium in the middle ear and/or mastoid process. Although cholesteatomas are not classified as either tumors or cancers, they can still cause significant problems because of their erosive and expansile properties resulting in the destruction of the bones of the middle ear (ossicles), as well as their possible spread through the base of the skull into the brain. They are also often infected and can result in chronically draining ears.
Granular myringitis (GM) is a long term condition in which there is inflammation of the tympanic membrane in the ear and formation of granulation tissue within the tympanic membrane. It is a type of otitis externa.
Without treatment it can lead to narrowing of the ear canal. A number of treatment options exist including putting vinegar in the ear, using antibiotic drops, and surgery.
Patients usually present with otorrhea, conductive hearing loss, and otalgia, while bleeding and a sensation of a mass are much less common.
Although imaging is not required to yield a diagnosis, it may be obtained to exclude other disorders, such as a concurrent cholesteatoma.
A tumor compressing the facial nerve anywhere along its complex pathway can result in facial paralysis. Common culprits are facial neuromas, congenital cholesteatomas, hemangiomas, acoustic neuromas, parotid gland neoplasms, or metastases of other tumours.
Often, since facial neoplasms have such an intimate relationship with the facial nerve, removing tumors in this region becomes perplexing as the physician is unsure how to manage the tumor without causing even more palsy. Typically, benign tumors should be removed in a fashion that preserves the facial nerve, while malignant tumors should always be resected along with large areas of tissue around them, including the facial nerve. While this will inevitably lead to heightened paralysis, safe removal of a malignant neoplasm is worth the often treatable palsy that follows. In the best case scenario, paralysis can be corrected with techniques including hypoglossal-facial nerve anastomosis, end-to-end nerve repair, cross facial nerve grafting, or muscle transfer/transposition techniques, such as the gracilis free muscle transfer.
Patients with facial nerve paralysis resulting from tumours usually present with a progressive, twitching paralysis, other neurological signs, or a recurrent Bell's palsy-type presentation.
The latter should always be suspicious, as Bell's palsy should not recur. A chronically discharging ear must be treated as a cholesteatoma until proven otherwise; hence, there must be immediate surgical exploration. Computed tomography (CT) or magnetic resonance (MR) imaging should be used to identify the location of the tumour, and it should be managed accordingly.
Other neoplastic causes include leptomeningeal carcinomatosis.
Facial nerve paralysis is characterised by unilateral facial weakness, with other symptoms including loss of taste, , and decreased salivation and tear secretion. Other signs may be linked to the cause of the paralysis, such as s in the ear, which may occur if the facial palsy is due to shingles. Symptoms may develop over several hours. Acute facial pain radiating from the ear may precede the onset of other symptoms.
Presbycusis (also spelled presbyacusis, from Greek "presbys" “old” + "akousis" “hearing”), or age-related hearing loss, is the cumulative effect of aging on hearing. It is a progressive and irreversible bilateral symmetrical age-related sensorineural hearing loss resulting from degeneration of the cochlea or associated structures of the inner ear or auditory nerves. The hearing loss is most marked at higher frequencies. Hearing loss that accumulates with age but is caused by factors other than normal aging (nosocusis and sociocusis) is not presbycusis, although differentiating the individual effects of distinct causes of hearing loss can be difficult.
The cause of presbycusis is a combination of genetics, cumulative environmental exposures and pathophysiological changes related to aging. At present there are no preventative measures known; treatment is by hearing aid or surgical implant.
Presbycusis is the most common cause of hearing loss, afflicting one out of three persons by age 65, and one out of two by age 75. Presbycusis is the second most common illness next to arthritis in aged people.
Many vertebrates such as fish, birds and amphibians do not suffer presbycusis in old age as they are able to regenerate their cochlear sensory cells, whereas mammals including humans have genetically lost this regenerative ability.
Primary symptoms:
- sounds or speech becoming dull, muffled or attenuated
- need for increased volume on television, radio, music and other audio sources
- difficulty using the telephone
- loss of directionality of sound
- difficulty understanding speech, especially women and children
- difficulty in speech discrimination against background noise (cocktail party effect)
Secondary symptoms:
- hyperacusis, heightened sensitivity to certain volumes and frequencies of sound, resulting from "recruitment"
- tinnitus, ringing, buzzing, hissing or other sounds in the ear when no external sound is present
- vertigo and disequilibrium
Usually occurs after age 50, but deterioration in hearing has been found to start very early, from about the age of 18 years. The ISO standard 7029 shows expected threshold changes due purely to age for carefully screened populations (i.e. excluding those with ear disease, noise exposure etc.), based on a meta-analysis of published data. Age affects high frequencies more than low, and men more than women. One early consequence is that even young adults may lose the ability to hear very high frequency tones above 15 or 16 kHz. Despite this, age-related hearing loss may only become noticeable later in life. The effects of age can be exacerbated by exposure to environmental noise, whether at work or in leisure time (shooting, music, etc.). This is noise-induced hearing loss (NIHL) and is distinct from presbycusis. A second exacerbating factor is exposure to ototoxic drugs and chemicals.
Over time, the detection of high-pitched sounds becomes more difficult, and speech perception is affected, particularly of sibilants and fricatives. Patients typically express a decreased ability to understand speech. Once the loss has progressed to the 2-4kHz range, there is increased difficulty understanding consonants. Both ears tend to be affected. The impact of presbycusis on communication depends on both the severity of the condition and the communication partner.
Ear pain can be caused by disease in the external or middle ear(because of infection), or inner ear, but the three are indistinguishable in terms of the pain experienced.
External ear pain may be:
- Mechanical: trauma, foreign bodies such as hairs, insects or cotton buds.
- Infective (otitis externa): "Staphylococcus", "Pseudomonas", "Candida", herpes zoster, or viral Myringitis. (See Otitis externa)
Middle ear pain may be:
- Mechanical: barotrauma (often iatrogenic), Eustachian tube obstruction leading to acute otitis media.
- Inflammatory / infective: acute otitis media, mastoiditis.
With patulous Eustachian tube, variations in upper airway pressure associated with respiration are transmitted to the middle ear through the Eustachian tube. This causes an unpleasant fullness feeling in the middle ear and alters the auditory perception. Complaints seem to include muffled hearing and autophony. In addition, patulous Eustachian tube generally feels dry with no clogged feeling or sinus pressure.
Some patients with this condition are disturbed by the perceived volume of their voice, causing them to speak very quietly. Their own voice may also sound lower to other people, because the trachea has more volume when the Eustachian tube is open. The patient may also sound as if they have congestion when speaking. Some sufferers may have difficulty in normal activities. They may also experience increased breathing rate, such as that brought on by physical activity. The increased activity not only increases the rate and force of pressure changes in the airway, which is therefore transmitted more forcefully into the middle ear, but also drives increased blood flow to peripheral muscles, compounding the problem by further depleting the Eustachian tube of extracellular fluid and increasing patency. The combination can lead to severe exacerbation of the symptoms. The urge to clear the ear is often mentioned.
Blepharochalasis results from recurrent bouts of painless eyelid swelling, each lasting for several days. This is thought to be a form of localized angioedema, or rapid accumulation of fluid in the tissues. Recurrent episodes lead to thin and atrophic skin. Damage to the levator palpebrae superioris muscle causes ptosis, or drooping of the eyelid, when the muscle can no longer hold the eyelid up.
Fluid accumulation is the most common cause of conductive hearing loss in the middle ear, especially in children. Major causes are ear infections or conditions that block the eustachian tube, such as allergies or tumors. Blocking of the eustachian tube leads to decreased pressure in the middle ear relative to the external ear, and this causes decreased motion of both the ossicles and the tympanic membrane.
- acute or serous otitis media
- otitis media with effusion or 'glue ear'
- Perforated eardrum
- Chronic suppurative otitis media (CSOM)
- Cholesteatoma
- Otosclerosis, abnormal growth of bone in or near the middle ear
- middle ear tumour
- ossicular discontinuity as a consequence of infection or temporal bone trauma
- Congenital malformation of the ossicles. This can be an isolated phenomenon or can occur as part of a syndrome where development of the 1st and 2nd branchial arches is seen such as in Goldenhar syndrome, Treacher Collins syndrome, branchio-oto-renal syndrome etc.
- Barotrauma unequal air pressures in the external and middle ear. This can temporarily occur, for example, by the environmental pressure changes as when shifting altitude, or inside a train going into a tunnel. It is managed by any of various methods of ear clearing manoeuvres to equalize the pressures, like swallowing, yawning, or the Valsalva manoeuvre. More severe barotrauma can lead to middle ear fluid or even permanent sensorineural hearing loss.
Conductive hearing loss occurs when there is a problem conducting sound waves anywhere along the route through the outer ear, tympanic membrane (eardrum), or middle ear (ossicles).
This type of hearing loss may occur in conjunction with sensorineural hearing loss (mixed hearing loss) or alone.
Dermatochalasis is sometimes confused with blepharochalasis, but these are two different conditions.
Ear pain is the predominant complaint and the only symptom directly related to the severity of acute external otitis. Unlike other forms of ear infections, the pain of acute external otitis is worsened when the outer ear is touched or pulled gently. Pushing the tragus, the tablike portion of the auricle that projects out just in front of the ear canal opening, also typically causes pain in this condition as to be diagnostic of external otitis on physical examination. People may also experience ear discharge and itchiness. When enough swelling and discharge in the ear canal is present to block the opening, external otitis may cause temporary conductive hearing loss.
Because the symptoms of external otitis lead many people to attempt to clean out the ear canal (or scratch it) with slim implements, self-cleaning attempts generally lead to additional traumas of the injured skin, so rapid worsening of the condition often occurs.
Ear pain, also known as otalgia , is pain in the ear. Primary ear pain is pain that originates inside the ear. Referred ear pain is pain that originates from outside the ear.
Ear pain is not always associated with ear disease. It may be caused by several other conditions, such as impacted teeth, sinus disease, inflamed tonsils, infections in the nose and pharynx, throat cancer, and occasionally as a sensory aura that precedes a migraine.
There are no objective physical examination findings that definitely diagnose ENS. Generally, one or more turbinates may be reduced or absent when viewed in medical imaging or via endoscope with no sign of physical obstruction, the mucosa will be dry and pale, and there may be signs of secondary infection.
Symptoms of ENS include a sensation of being unable to breathe, a feeling of nasal obstruction and dryness, and crusting, oozing, and foul smells inside the nose from infections. A person with ENS may complain of pain in their nose or face, an inability to sleep and fatigue, and of feeling irritated, depressed, or anxious; they may be constantly distracted by the sense that they are not getting enough air.
Psychogenic aphonia is often seen in patients with underlying psychological problems. Laryngeal examination will usually show bowed vocal folds that fail to adduct to the midline during phonation. However, the vocal folds will adduct when the patient is asked to cough. Treatment should involve consultation and counseling with a speech pathologist and, if necessary, a psychologist.
In this case, the patient's history and the observed unilateral immobility rules out function aphonia.
Injuries are often the cause of aphonia . Minor injuries can affect the second and third dorsal area in such a manner that the lymph patches concerned with coordination become either atrophic or relatively nonfunctioning. Tracheotomy can also cause aphonia.
Any injury or condition that prevents the vocal cords, the paired bands of muscle tissue positioned over the trachea, from coming together and vibrating will have the potential to make a person unable to speak. When a person prepares to speak, the vocal folds come together over the trachea and vibrate due to the airflow from the lungs. This mechanism produces the sound of the voice. If the vocal folds cannot meet together to vibrate, sound will not be produced. Aphonia can also be caused by and is often accompanied by fear.
This uncommon tumor accounts for less than 2% of all ear tumors. While patients present with symptoms related to the middle ear cavity location of the tumor, the tumor may expand into the adjacent structures (external auditory canal, mastoid bone, and eustachian tube). Patients come to clinical attention with unilateral (one sided) hearing loss, usually associated with decreased auditory acuity, and particularly conductive hearing loss if the ossicular bone chain (middle ear bones) is involved. Tinnitus (ringing), otitis media, pressure or occasionally ear discharge are seen. At the time of otoscopic exam, the tympanic membrane is usually intact, with a fluid level or mass noted behind the ear drum. Even though this is a "neuroendocrine" type tumor, there is almost never evidence of neuroendocrine function clinically or by laboratory examination.
