Chronic otitis media is generally associated with some degree of hearing loss, which is often the patient’s chief complaint. This hearing loss is usually conductive, resulting from tympanic membrane rupture and/or changes in the ossicular chain due to fixation or erosion caused by the chronic inflammatory process. When cholesteatoma or granulation tissue is present in the middle ear cleft, the degree of ossicular destruction is even greater. An issue that has recently gained attention is… Expand
Sensorineural hearing loss in patients with chronic suppurative otitis media: Is there a significant correlation?
It is demonstrated that CSOM is associated with some degree of SNHL and cochlear damage, and higher frequencies are more affected, and aging can act as a precipitating factor in this pathological process. Expand
Sensorineural hearing loss in chronic otitis media: analysis of an overlooked entity!
Significant sensorineural hearing loss is seen in chronic otitis media which was greater in squamosal disease than in mucosal disease. Expand
It is found that the longer the duration of the disease and the more complicated the pathology, the more the loss in bone conduction is found. Expand
Incidence of Sensorineural Hearing Loss in CSOM
Background: Sensorineural hearing loss is a common sequel of chronic suppurative otitis media and the round window membrane is currently being considered as a major route for noxious agent to passExpand
Chronic Otitis Media and its Correlation with Unilateral Sensorineural Hearing Loss in a Tertiary Care Centre of North India
Assessment of relationship between sensorineural hearing loss and chronic otitis media and association of bone conduction between diseased ear and contralateral normal ear found that SNHL does not change with age but with duration and Bone conduction threshold tends to increase with increasing frequency. Expand
Background: Sensorineural hearing loss may be one of the outcome of chronic suppurative otitis media. Objective: To evaluate the association of chronic suppurative otitis media with sensorineuralExpand
Sensorineural hearing loss in the acute phase of a single episode of acute otitis media.
During the first 7 days after the onset of an isolated episode of acute otitis media, significant increases in bone and air thresholds at all frequencies, especially >2 kHz, as compared with healthy ears are observed. Expand
Abnormal CT Findings Are Risk Factors for Otitis Media-Related Sensorineural Hearing Loss
Evaluated risk factors by computed tomography findings for COM-related SNHL in patients with unilateral COM found the presence of soft tissue density in the antrum, determined from temporal bone CT, increased the OR of SNHL to 3.8. Expand
Risk factors for sensorineural hearing loss in pediatric chronic otitis media.
The degree of SNHL in the diseased ear at 2000Hz was found to be significantly correlated with the presence of cholesteatoma and with age above 10 years, and it is imperative to actively treat pediatric patients diagnosed with COM, with the aim of preventing the possible development ofSNHL. Expand
Correlation Between Sensorineural Hearing Loss and Chronic Otorrhea
A correlation between sensorineural hearing loss and the chronic otorrhea was observed, in comparison both with contralateral normal ears and with dry perforated ears of other patients. Expand

The inner ear is vulnerable against chronic suppurative otitis media, as reflected by the fact that sensory cells processing higher frequencies are more seriously damaged. Expand
Sensorineural hearing loss in chronic otitis media.
The presence of cholesteatoma and/or ossicular erosion was not associated with a significantly increased risk of sensorineural hearing loss and the effect of duration of disease on the degree of SNHL was analysed but no correlation was found. Expand
Chronic otitis media and sensorineural hearing loss: is there a clinically significant relation?
It is concluded that COM may cause SNHL, but in the vast majority of patients this loss is not clinically significant, and various COM parameters were studied to determine if a correlation with the severity of the SNHL existed. Expand
Thickness of the human round window membrane in different forms of otitis media.
The thickness and morphologic characteristics of the round window membrane were evaluated in temporal bones from normal subjects as well as those with serous otitisMedia, purulent otitis media, and chronic otitismedia, showing an involvement of all layers of theround window membrane in those groups with Otitis media.

Ototoxicity and ototopical medications: a survey of otolaryngologists.
In an attempt to define the clinical parameters and relevance of ototopical medications, including their usefulness in permanent inner ear damage, a questionnaire survey was sent to 7463Expand
[Risk of inner ear damage from ototoxic eardrops (author's transl)].
Antibiotic eardrops with ototoxic properties are widely used in the treatment of discharging ears and have also been used in cases with perforated tympanic membranes. There has thus far been noExpand
Ototoxicity of ear drops: a clinical perspective.
The authors emphasize patient education, application of topical ear drops using soaked gauze strips, and documentation of the patients hearing status at the beginning of the treatment regimen. Expand
Breakdown of the round window membrane permeability barrier evoked by streptolysin O: possible etiologic role in development of sensorineural hearing loss in acute otitis media
It is proposed that damage to the RWM by potent pore-forming cytolysins leads to leakage of ions from the perilymph, which could contribute to disturbances of the inner ear function. Expand
