Sensorineural hearing loss (SNHL) occurs when there is damage to the inner ear (cochlea) or to the nerve pathways from the inner ear to the brain. Sometimes a conductive hearing loss occurs in combination with a sensorineural hearing loss.

Sensorineural hearing loss is the most common type of hearing loss, occurring in 23% of population older than 65 years of age. Infections, such as meningitis, are a common cause of hearing loss in children where it occurs in approximately 20% of those with streptococcus pneumoniae meningitis (Heckenberg et al 2011). Noise induced hearing loss is a permanent hearing impairment resulting from prolonged exposure to high levels of noise. Children who are born prematurely or contract certain infections in utero are at a higher risk of hearing loss (Hille et al 2007, Roizen 2003). While very unusual, acoustic neuromas or metastatic cancer (particularly breast) can be a source of hearing loss. Sudden hearing loss (SHL) is defined as greater than 30 dB hearing reduction, over at least three contiguous frequencies, occurring over 72 hours or less. Sensory presbyacusis is caused by loss of sensory elements in the basal (high-frequency) end of the cochlea with preservation of neurons.
Cochlear conductive presbyacusis is caused by thickening of the basilar membrane caused by deposition of basophilic substance. Because presbycusis occurs in some individuals as they age but not in others, genetic or environmental factors must also play a role in its development (Liu & Yan 2007).
In conductive hearing loss, the second most common form of hearing loss, sound is not transmitted into the inner ear. Images marked as copyright Northwestern University were developed with the support of a National Institutes of Health (NIH) grant to Northwestern University Dept. The American Hearing Research Foundation is a non-profit foundation that funds research into hearing loss and balance disorders related to the inner ear and is also committed to educating the public about these health issues. A 12 year old girl presented with a combination of unilateral sensorineural deafness and amelogenesis imperfecta. It seems likely therefore that the amelogenesis imperfecta is a hypomineralised rather than a hypoplastic variant.
The 12 year old girl with amelogenesis imperfecta, unilateral hearing loss, and nail abnormalities. Permanent dentition in index case illustrating extensive enamel discoloration of incisors, canines, and premolars. The combination of sensorineural hearing loss, amelogenesis imperfecta, and nail abnormalities was first reported by Heimler et al.

Introduction: The sudden sensorineural hearing loss is a devastating condition that could be a complication of some medical or surgical procedures. Objective: To report a case of sudden sensorineural hearing loss after general anesthesia to laparoscopic colecistectomy. Clinical findings: Male, 63 years, habitual smoker, with previous diagnostic of chronic obstructive pulmonary disease, who was submitted to laparoscopic colecistectomy under general anesthesia with sevoflurane. INTRODUCTIONHearing loss followed by non-otologic surgical procedures is not often mentioned in the literature, it is associated to cardiopulmonary bypass and rachidian anesthesia most of time.Perioperatory hearing alterations is a little reported process, though it seems to be more frequent from surgeon and anesthesiologist viewpoint.
The outer ear includes the auricle, the external auditory canal, and the lateral surface of the tympanic membrane (TM). Postmeningitic hearing loss can be due to lesions of the cochlea, brainstem and higher auditory pathways, but usually is related to suppurative labyrinthitis (cochlear damage). One in 10 Americans has a hearing loss that affects his or her ability to understand normal speech. Much research has focused on the detection of genetic causes of hearing loss, and many of them can now be diagnosed at an early age (Blanchard et al 2012, Dror & Avraham 2009, Kochhar et al 2007, Kokotas et al 2007, Robin et al 2005, Xing et al 2007). Risk factors that correlate with hearing loss in premature infants include hypoxia, mechanical ventilation, hyperbilirubinemia, very low birth weight, and the use of ototoxic medications.
It occurs most frequently in the 30- to 60-year age group and affects males and females equally.
These patients have symmetrical, high-frequency sensorineural hearing loss (as shown in Figure 3). Medical conditions that are common in the elderly, such as diabetes and stroke, may also increase the risk of hearing loss with aging (Bainbridge et al 2010, Helzner et al 2005, Maia & Campos 2005, Schreiber et al 2010).
Causes include a buildup of ear wax, a foreign body in the ear canal, otosclerosis, tympanosclerosis (as shown in Figure 4), external or middle ear infections (otitis externa or media), allergy with serous otitis media, trauma to the ossicular chain such as temporal bone fracture, tumors of the middle ear, erosion of the ossicular chain (cholesteatoma) and perforation of the tympanic membrane. She had a fair complexion (fig 1) and examination of her nails showed multiple transverse grooves (Beau's lines) on several fingers and toes (fig 2A, B). Ground sections of permanent premolars, extracted for orthodontic purposes, showed dentine and enamel of normal thickness.
The physiopatologic mechanisms involved are diverse and complex and this become difficult the prevention and treatment.
Some circunstances which involve surgical work can simulate those alterations or can be of no notice because of its subclinical nature if audiometry is not done. The middle ear includes the medial surface of the TM, the ossicular chain, the eustachian tube, and the tympanic segment of the facial nerve.
These conditions are relatively common in premature infants, and the majority do not go on to develop hearing deficits. Hearing loss in adults surviving pneumococcal meningitis is associated with otitis and pneumococcal serotype.


Race and sex differences in age-related hearing loss: the Health, Aging and Body Composition Study. I was already decribed with almost all anaesthesic techniques from local anaesthesia to general one, discussing in each of the cases a series of self or associated mechanisms (1).In the case of epidural anesthesia or lumbar puncture, hearing loss has been often reported (1-3). The inner ear includes the auditory-vestibular nerve, the cochlea and the vestibular system (semicircular canals).
The National Institute of Health reports that about 15 percent of Americans aged 20 to 69 have high frequency hearing loss related to occupational or leisure activities. If the loss is minor, then avoidance of noise and ototoxic medications may be an appropriate treatment. Therefore, we are not always aware that this might happen, and even more, if we have in mind that the specific presentation and the beginning of the defict can widely vary (4), and that does not have great audiometric studies about and we cannot have an accurate idea of their clinical or subclinical incidence. Trauma is more likely to affect hearing in patients who suffer a temporal bone fracture or are older in age (Bergemalm, 2003).
Because of occupational risk of noise induced hearing loss, there are government standards regulating allowable noise exposure.
From all studies, it is estimated that from 10% to 50% of the patients who had espinal anaesthesia can undertake hearing deficit measured in audiometric way in low frequencies, though only one fourth of them presented clinical manifestations (1). People working before the mid 1960s may have been exposed to higher levels of noise where there were no laws mandating use of devices to protect hearing.
Occasionally, persons with acquired deafness can be treated surgically with a surgically implanted device, a cochlear implant. In other cases of local anaesthesia as blocking of plexes (5) or odontological anaesthsia with the blocking of nerve (6) it was also reported hearing loss. It is known that 0.4% of the patients submitted to spinal anesthesia undertake some type of hearing perturbation (1). MICHAEL (20) has described sensorineural hypoacusis followed by mielography, lumbar punction and spinal anesthesia. From 10 to 50% of the patients who had epidural anesthesia undertook mesurable hearing defict in low frequencies, therefore less than one fourth is clinically known (1-3,20). Audiometry done soon after surgery.From the cases of sudden sensorineural hypoacusis followed by non-otological surgery under general anesthesia, most of them refers to patients submitted to cardiopulmonary bypass syrgery (1,7). In the current report, we have presented hearing loss associated to general anesthesia to laparoscopic surgery. In the revised literature, we discussed about 40 documented cases of hearing loss followed by general anesthesia, only one of them in relation to laparoscopic surgery, and the second reported, the current one, in relation to general anesthesia and laparoscopic surgery and the first in which sevoflurane was the only anesthesia gas used.
