Sensorineural hearing loss in patients with chronic otitis media

Acta Oto-laryngologica, 2013

Conclusions: Risk factors for sensorineural hearing loss (SNHL) development in patients with chronic otitis media (COM) are longer duration of disease, older age and the presence of cholesteatoma. To prevent the expected development of SNHL, it is imperative to treat COM actively. Objectives: To assess the severity of SNHL in patients with unilateral COM and to define risk factors for its development. Methods: The study included 317 patients with unilateral COM. Mean age was 28.7 ± 16.7 years (range 7-78 years) and mean duration of disease was 12.2 ± 11.3 years (range 0.25-60 years). In all patients, air conduction (AC) and bone conduction (BC) thresholds in both ears were measured at 500, 1000, 2000 and 4000 Hz. The parameters evaluated were demographics, duration of disease, presence and location of cholesteatoma and otologic history. Results: The difference in mean BC thresholds between the diseased ears and the healthy ears was statistically significant, ranging from 4.55 ± 10.89 dB to 12.55 ± 19.09 dB across the measured frequency range (p < 0.0001). Multivariate regression analysis revealed statistically significant correlations between advanced age, longer duration of disease and presence of cholesteatoma, and the BC threshold differences between the affected and healthy ears.

Introduction: Long-standing chronic otitis media (COM) may lead to sensorineural hearing loss (SNHL). The present study aimed to evaluate the factors affecting the sensorineural component to counsel patients regarding the risk of SNHL at the event of untreated COM. Material and Methods: A time-bound cross-sectional study was conducted in the Department of Otorhinolaryngology at a tertiary care hospital. The study population included the study group comprising 137 patients with chronic suppurative otitis media (CSOM) and the control group which consisted of 137 individuals with the same age range and gender as the case study group. Moreover, the hearing was assessed using a pure tone audiogram and special tests of hearing. Results: Based on the findings of the present study, the SNHL was found in 71.4% of CSOM cases with an ear discharge duration of more than 5 years. The SNHL occurred in 55.2% and 44.7% of the cases with pars flaccida and of pars tensa perforations, respectively. In...

Background: The sensorineural component of hearing loss either in form of pure sensorineural or Mixed components has since long been suspected to be a dreaded sequela of chronic suppurative otitis media (CSOM). The aim of this study is to access the incidence of sensorineural hearing loss (SNHL) or mixed hearing loss (MHL) amongst people suffering from both mucosal and squamosal variants of CSOM.Methods: A prospective observational cohort study (control group: contralateral ear) was conducted at the E.N.T. department of tertiary care center from December 2020 to September 2022. 149 patients of ages 15-50 of either gender with unilateral CSOM were included in the study. The other normal ear of the same patient was taken as the control ear. The pure tone audiometry of both diseased and control ears at frequencies 500,1000,2000 and 4000 kHz were taken to determine SNHL or MHL.Results: The mean age was 26.54±8.75 years of which, 79 males and 70 females. The mean duration of disease was ...

Objective: Although the incidence and prevalence of chronic suppurative otitis media (CSOM) is decreased in recent decades, but it is still a major health problem in both developing and developed countries. CSOM has major and life-threatening complications such as hearing loss, meningitis and cerebral abscess. Since hearing loss is the most common complication of CSOM, we aimed to evaluate audiometric profile in patients with CSOM and its relation with intraoperation pathologic findings Methods: 80 patients were entered in this study, which were selected from CSOM patients who underwent tympanomastoidectomy or tympanoplasty between 2008 and 2010 in otolaryngology wards of an academic referral hospital. The detailed patients' history, physical examination, audiometric evaluations and findings during surgeries were collected. Finally, the association between data were analyzed.

Chronic suppurative otitis media (COM) is reported to cause elevation of bone-conduction thresholds either by damage to cochlear sensorineural structures or by alteration in the mechanics of sound transmission in the ear. A retrospective study was made of the medical records of 87 patients with unilateral uncomplicated COM to document that abnormality in bone conduction does exist. In a separate study the cochlear pathology in 12 pairs of temporal bones with unilateral COM was studied by light microscopy. Infected ears showed higher than normal mean bone-conduction thresholds by amounts ranging from 1 dB at 500 Hz to 9.5 dB at 4,000 Hz. The temporal bones showed no greater loss of specialized sensorineural structures in infected ears than in normal control ears. Because there is no evidence that COM caused destruction of hair cells or cochlear neurons, alteration in the mechanics of sound transmission becomes a more plausible ex planation for the hearing losses.

Worldwide the chronic suppurative otitis media (CSOM) is one of the most common infectious diseases in childhood and is a common cause of impaired hearing. The disease remains a challenging entity for the healthcare system of resource-limited nations despite the advances in modern medicine. The nature of hearing loss in CSOM is mainly conductive, the sensorineural hearing loss (SNHL) is also reported in such patients. The purpose of the study was to identify SNHL in patients with the mucosal type of CSOM and to find the impact of longterm discharging ears on bone conduction (BC) thresholds. Methods Patients with a diagnosis of the mucosal type of CSOM were identified from the record of ENT, Head and Neck Surgery clinic between January 2019 and January 2020. The patients were divided into three groups based on the duration of the disease: groups I, II, and III for 1-5 years, 5-10 years, and 10-15 years, respectively. Pure tone audiogram was reviewed, and data of BC was recorded for 500, 1000, and 2000 Hz. The descriptive frequency was calculated for SNHL in each group and group I was compared with other groups using a chi-square test. The mean BC threshold of group I was compared with other groups using a t-test. SPSS version 26 (IBM Corp., Armonk, New York) was used for statistical analysis.

C hronic otitis media (COM) is a major health problem, especially in developing and underdeveloped countries. The chronic nature of the disease can lead to repeated hospital visits and increased financial burden, hearing loss, and related social problems concerning ear discharge, education/learning difficulties, and especially in untreated cases, life-threatening complications. COM is a disease that can affect both ears. Therefore, it is important to know the findings of the contralateral ears other than the affected ears to determine the changes in the tympanic membrane before the onset and during COM in this ear. For this purpose, the data of the patients who were operated on for COM between 2014 and 2017 were reviewed retrospectively. Otoscopic findings, audiologic examinations, and tomography images of the ipsilateral and contralateral ears of the patients were evaluated. Methods In this study, a total of 295 (131 females/164 males) patients who had been operated for the management of COM at the Objectives: Chronic otitis media (COM) reveals a spectrum of otoscopic findings, and both ears may be affected to a different degree. The analysis of contralateral ear in patients with COM is important to detect the early signs of the disease. This may enable the follow-up and treatment of abnormalities in contralateral ear without delay. Therefore, in this study, we aimed to investigate the otoscopic and audiologic findings of contralateral ears of patients with COM. Methods: The institutional data of patients who underwent surgical treatment between 2014 and 2017 due to COM were reviewed. Suppurative ears with cholesteatoma, polyps, and otorrhea refractory to medical treatment and ears with dry middle ear mucosa, with otorrhea responsive to medical treatment, and without cholesteatoma were divided into two groups (Group 1 and Group 2, respectively). All patients were examined with regard to the presence of perforation, retraction, myringosclerosis, atrophy, and audiological results before the groups were compared. Results: Approximately 50% of contralateral ears of patients with COM showed abnormalities at an otoscopic examination in both groups. Tympanic membrane retraction in Group 1 was greater than in Group 2, and the difference was statistically significant (p<0.05). Both the mean air and bone conduction thresholds of the contralateral ears in Group 1 were also found to be elevated when compared with Group 2, and the differences were statistically significant (p<0.05). Conclusion: COM may be seen bilaterally due to the same predisposing factors affecting the ears. Therefore, detection, followup, and early treatment of abnormalities of contralateral ear associated with otitis media have clinical importance in the prevention or delaying progression of these abnormalities to COM.
