“…In India, the prevalence of the disease is approximately 16/1000 in urban population and 46/1000 in rural population. [1][2][3][4] CSOM is of two types, tubotympanic or mucosal type; and atticoantral or squamosal type. CSOM is known to cause several major and sometimes life threatening complications such as hearing loss, extradural abscess, subdural abscess, meningitis, cerebral abscess, lateral sinus thrombosis, mastoiditis and facial paralysis.…”

Background: Hearing loss associated with the CSOM affects the patients’ communication with others and results in poor quality of life. Degree and type of hearing loss can be assessed by pure tone audiometry, which helps in predicting the status of tympanic membrane, ossicular chain, and inner ear and also helps in preoperative planning.Methods: Patients with CSOM aged 10 years and above were included in the study. All patients underwent pure tone audiometry. With the help of air and bone conduction threshold, the degree and type of hearing loss in each ear was determined. The data collected was evaluated and results are reported as rates and proportions (%). Results: Most of the ears (83%) had mild to moderate hearing loss. Average ABG observed was 31 dB. Maximum ABG observed was 55dB on right side and 50 dB on the left side. There was mixed hearing loss in 10.9% cases.Conclusions: This study reinforces the idea of using preoperative pure tone audiometry, which not only helps in planning surgery but also helps in documenting the preoperative status of patients’ sensorineural hearing loss, if present.

Purpose: This study is directed towards establishing a correlation between the objective measurement of tympanic membrane (TM) perforation size with hearing loss in patients with inactive mucosal chronic otitis media (COM), and to compare the otoscopic findings of the TM perforation vis-a-vis the results obtained by image analysis of the endoscopic image of the perforation. Materials and methods: An observational, prospective and hospital based study was performed on 107 ears (78 patients) with inactive mucosal chronic otitis media. Objective measurement of the TM perforation size was done by capturing the images of the perforation on ImageJ analysis software. A correlation was established between the hearing loss and the perforation with respect to its size and location. The accuracy of the otoscopic finding of the perforation was established with respect to the endoscopic image of the perforation. Results: The extent of the hearing loss was seen to increase with increasing size of the TM perforation (r = 0.435, p < 0.0001). Posterior perforations had a 12% greater hearing loss than anterior perforations but this was significant only at the frequency of 500 Hz (p = 0.02). There was a positive correlation between the otoscopic estimation of the size of the perforation with the endoscopically obtained image. Conclusion: Hearing loss in chronic otitis media is directly proportional to the size of the TM perforation and posteriorly based perforations have worse audiometric thresholds at lower frequencies (500 Hz).

Background: The more severe the middle ear inflammation with chronic suppurative otitis media (CSOM), the more likely its contralateral middle ear suffers from chronic otitis media. Paparella’s continuum theory describes otitis media as a continuous and dynamic inflammation that starts from eustachian tube blockage. This ongoing and prolonged inflammation may affect the contralateral ear (CLE), manifesting in bilateral chronic otitis media. Methods: A cross-sectional study on 42 medical records of CSOM patients hospitalized for middle ear surgery. In this research, we used the middle ear risk index (MERI) scoring to measure CSOM severity, which is estimated to affect air conduction (AC) threshold of the CLE by interfering with its middle ear impedance. The correlation between the MERI score of the CSOM ear and AC of the CLE was analyzed using the Pearson correlation test. Results: There was a strong positive correlation between the MERI score of CSOM with cholesteatoma and its CLE AC threshold (r = 0.610, P < 0.01), while the MERI score of CSOM without cholesteatoma had a weak positive correlation with its CLE AC (r = 0.384, P < 0.05). Conclusions: The higher MERI scores in either CSOM with cholesteatoma or without cholesteatoma were correlated to higher CLE AC threshold.
