Clinical Profile of Squamosal Chronic Otitis Media among Paediatric and Adult Patients in Rural Population of Central India: A Cross-sectional Study

Introduction: Chronic Otitis Media (COM) is one of the major preventable causes of hearing impairment, especially in children. Hearing loss in children affects speech, language, communication, auditory processing, psychosocial and cognitive development, and academic progress. Since studies addressing and comparing COM in the paediatric and adult population are few and far between, present study attempted to fill this research hiatus.

Aim: To analyse and compare the clinical profile of squamosal COM in paediatric and adult populations.

Materials and Methods: The present cross-sectional study was carried out in the Department of Otorhinolaryngology, Acharya Vinod Bhave Hospital, Sawangi, Wardha, Maharashtra, India, from December 2020 to December 2022. All the selected patients with squamosal COM (active or inactive) in the paediatric age group (0-15 years) and adult age group (16-60 years) was considered in this study. The study included 26 patients and was evaluated based on intraoperative and radiological findings such as grades of retraction pocket, extent of ossicular erosion, extent, and spread of granulation and cholesteatoma, and pneumatisation pattern among both age groups were carefully analysed. Chi-square test (χ2) of independence was used to compare data between the two groups. A p-value ≤0.05 was considered statistically significant.

Results: Erosion of scutum was predominantly noted in 6 (42.9%) paediatric patients. In both age groups, attic perforation were more common than marginal perforation, which was found to be statistically significant (p-value=0.045). Grade-2 Posterosuperior Retraction Pocket (PSRP) in paediatric (2, 14.2%) and Grade-4 PSRP in adults (4, 33.3%) were commonest whereas none of the paediatric patients showed Grade-4 PSRP. This difference in PSRP grade in both age groups was found statistically significant (p-value=0.038). Short process of incus was more frequently involved in 3 (25.0%) paediatric and long process of incus in 6 (60%) adult (p-value=0.040). There was frequent involvement of protympanum in 7 (50%) paediatric patients (p-value=0.035). Diploic pattern of pneumatisation was least common in both age groups.

Conclusion: Greater grades of PSRP were found among adult patients. This might be contributed to the longer duration of exposure to disease pathogenesis in adults. One of the vital features in the ossicular involvement is the total absence of incus and malleus more frequently in paediatric patients indicating its extensiveness.
