The Difference

Introduction: Chronic otitis media (COM) is one of the most common disorder in eld of ENT. Hearing loss as a sequel of chronic otitis media (COM) is often conductive, but there has been a controversy in different studies with association of sensorineural hearing loss and COM . The aim of the study was to determine the association between COM and sensorineural hearing loss (SNHL) and to assess the inuence of patient's age, duration of disease, type of COM and presence of cholesteatoma on the presence of SNHL. Material & Methods: This was a cross sectional descriptive study of 100 subjects between the age group of 5 and 50 years. Patients having unilateral chronic otitis media of both mucosal and squamosal types, who met the inclusion criteria of unilateral otorrhea, normal contralateral ear on otoscopy, with no history of head trauma or ear surgery or familial hearing loss were selected. All patients were evaluated clinically and audiologically. The age, type, duration of disease and presence of cholestetoma is correlated with degree of sensorineural hearing loss. Interaural differences in bone conduction thresholds at 500 Hz, 1 kHz, 2 kHz and 4 kHz were also noted. Data analysis was performed using SPSS 13 with independent-samples t-test, Pearson correlation test, and twotailed analysis. A p ≤ 0.05 was considered statistically signicant. Results: Signicant higher BC thresholds were found in the affected ear than in the normal ear for each frequency (p < 0.001), which increased with increasing frequency (4.9 dB at the 500 Hz and 9.85 dB at the 4000 Hz). A strongly signicant correlation was observed between patients' age and the degree of SNHL (r = 0.401, p < 0.001) but no signicant correlation was in duration of the disease (r = 0.108, p > 0.05). There was no relationship between presence of cholesteatoma with SNHL across all frequencies (p < 0.05). Conclusion: A signicant association between SNHL and COM was found in this study. The difference in BC thresholds increased with increasing frequency. Patients' age was signicantly correlated with the degree of SNHL, but no signicant association was observed between SNHL with duration of disease. Presence of cholesteatoma and development of SNHL were found to be correlated in this study.

Objective: We investigated the incidence of sensorineural hearing loss (SNHL) after chronic otitis media (COM) surgery and determined the associated factors. Methods: Data were collected via retrospective medical chart review. Results: Of the 192 patients, 82 underwent tympanoplasty, 26 underwent canal wall up mastoidectomy with tympanoplasty, and 84 underwent canal wall down mastoidectomy with tympanoplasty. After surgery, the average air conduction (AC) hearing threshold improved significantly, from 125 to 1000 Hz, but the average high-frequency AC and bone conduction (BC) hearing thresholds deteriorated significantly. In 21 (11%) cases, the BC hearing threshold worsened by more than 15 dB at 4000 Hz. When we compared these 21 cases to patients in whom hearing was preserved, the former group was found to be significantly younger and had a higher frequency of cholesteatomatous otitis media. However, when comparing the severity of inflammation in patients with temporal bone computed tomography, there was no significant difference between the 2 groups. Conclusions: High-frequency SNHL may develop after surgery to treat COM, especially in young patients with cholesteatoma.

Since the risk of sensorineural hearing loss from persistent chronic otitis media and mastoiditis is greater than the risk to loss of labyrinthine function from carefully performed surgery, it is felt that the best treatment for chronic suppurative middle ear disease in an only-hearing ear is surgical removal of disease. Between the years 1961 to 1970 14 cases of chronic otitis media and mastoiditis in only-hearing ears were treated surgically at the Massachusetts Eye and Ear Infirmary. Five cases presented with resistant foul otorrhea, while five patients presented with increasing hearing loss and four with vertigo. The patients with hearing loss and vertigo were subjected to surgery at the earliest possible date. Wide-field surgical exposure of the mastoid and middle ear spaces with thorough removal of diseased tissue was carried out. Particular attention to avoid injury to the labyrinth, either directly or indirectly, must be kept in mind and it is recommended that surgery in only-hearing ears be performed by only the most experienced and capable otologic surgeon. All 14 ears have remained dry after surgery. Hearing was significantly improved in ten cases, while two were unchanged and two were made worse, as regards the conductive loss only. In all 14 cases postoperative discrimination scores were normal, so that even those cases that did not achieve serviceable hearing levels from surgery were able to use amplification. The results in this series confirm the feeling that carefully performed and timed surgery is effective in controlling chronic suppurative disease, while preserving function in only-hearing ears.

The author's series of 168 consecutive cases of chronic otitis media from the years 1965 to 1972 were reviewed with regard to the occurrence and management of pathological fistulae in the bony labyrinth. Fourteen cases (incidence 8.3%), of which nine involved only the semicircular canals and five involved primarily the cochlear wall occasionally associated with a semicircular canal fistula, were examined particularly in terms of postoperative sensorineural hearing loss following removal of cholesteatoma matrix from the fistula. The results indicated that the matrix can be removed with reasonable safety from most small semicircular canal fistulae. Only when the cholesteatoma matrix is firmly adherent to a large area of membranous semicircular canal is removal not recommended. When the cholesteatoma was removed from three cochlear fistulae, sensorineural hearing loss resulted. In two cases with cochlear fistula, hearing was preserved when the cholesteatoma matrix was not removed from the fistulized area. These results have been used to formulate guidelines for the surgical management of pathological fistulae of the bony labyrinth.

AbstractThe sensorineural hearing loss in 150 patients with chronic otitis media who were treated in the Haifa Medical Center (Rothschild) during a ten year period was studied. There were 124 patients treated with a mixture containing neomycin, polymyxin B and dexamethasone and a control group of 26 patients with dexamethasone only.All patients were followed up for a period of 1–2 years. Patients with hearing loss due to factors such as previous ear surgery, family history, exposure to noise etc., have been excluded.The conclusions reached were that there is a relationship between the period of disease and the sensorineural hearing loss and that the local treatment with a mixture containing neomycin + polymyxin B appears to contribute to the worsening of the sensorineural hearing loss in patients with chronic otitis media.Our numbers are small and further studies must be done, but the fact that currently used ear drops may produce a sensorineural hearing loss should not be ignored.
