Assessment of Different Contributing Factors Leading to Discharging Mastoid Cavity after Canal Wall Down Procedures

Objective: To determine the frequency of different contributing factors leading to discharging mastoidcavity in patients undergoing canal wall down mastoidectomy.Material and Methods: The study was Cross-sectional which was conducted in the Department of ENT, Unit-II, Services Hospital, Lahore. Retrospective study of 6 months from 01/01/2024 to 30/06/2024 respectively.This study involved 25 patients having discharging ear for more than 3 months, presenting within 1 year afterundergoing canal wall down surgery. A written informed consent was taken from each patient.Results: The age of the patients ranged from 12 years to 65 years with a mean of 31.45±11.83 years. Therewere 13 (57.9%) male and 12 (42.1%) female patients in the study group. The time since operation atpresentation ranged from 12 weeks to 48 weeks with a mean of 27.96±10.28 weeks. Among the contributingfactors highest frequency was noted for narrow meatoplasty (82.1%), followed by residual cholesteatoma(70.5%), high facial ridge (65.3%), persistent air cells (50.5%) and remaining malleus head (25.3%). Whencross tabulated, there was no statistically significant difference in the frequency of narrow meatoplasty(p=.627), high facial ridge (p=.939), persistent air cells (p=.869) and remaining malleus head (p=.850) acrossvarious age groups. However, the frequency of residual cholesteatoma was significantly higher in youngerpatients; 12-29 years vs. 30-47 years vs. 48-65 years (84.2% vs. 53.3% vs. 37.5%; p=.001). There was also nostatistically significant difference in the frequency of narrow meatoplasty (p=.242), residual cholesteatoma(p=.581), high facial ridge (p=.206), persistent air cells (p=.743) and remaining malleus head (p=.689) acrossvarious genders. Similarly, there was also no statistically significant difference in the frequency of narrowmeatoplasty (p=.616), residual cholesteatoma (p=.381), high facial ridge (p=.671), persistent air cells (p=.468)and remaining malleus head (p=.391) across various groups according to time since operation at presentation.Conclusion: Among the contributing factors highest frequency was noted for narrow meatoplasty (82.1%),followed by residual cholesteatoma (70.5%), high facial ridge (65.3%), persistent air cells (50.5%) andremaining malleus head (25.3%). The frequency of residual cholesteatoma was significantly (p=.001) higherin younger patients.Keywords: Chronic Suppurative Otitis Media, Canal Wall Down Procedures, Discharging mastoid cavity,Contributing FactorHow to cite: Syed SH, Awan AA, Nadeem S, Rafiq F, Iftikhar M, Ahmad J.
