Comparative Study of Outcome of Tympanoplasty by Postauricular and Permeatal Approach

ABSTRACT

Background: As from time of residency, tympanoplasty is the most common operation performed by an otolaryngologist. Because of the continuing efforts of otologists all around the world to produce the maximum surgical outcome, significant improvements in this surgical method have developed during the middle ages. Objective: The aim of the study was to compare the outcome of Tympanoplasty in Postauricular and Permeatal Approach.Methods:A total of 74 patients between the age group 15 to 44 years who were attending the ENT OPD, suffering from Chronic Suppurative Otitis Media (CSOM) were selected on the basis of type of perforation and their workup was done to assess the candidature for tympanoplasty. Comparative analysis between the two groups were done based on analysis using SPSS 24 software version. The level of significance was set to 5% (p < 0.05).Results:A total of 74 patients were included in the study and the overall graft take was 76.92% in cases of Permeatal technique as compared to 91.66% in the case of postaural underlay technique. The complication of postaural approach higher than Permeatal approach. There was a difference in hearing improvement with majority of the cases improving to the range of 10-22 dB in Permeatal technique compared to 08-18 dB in Postaural Underlay technique.Conclusion:In terms of complications and hearing improvement, the Permeatal method outperforms the Postauricular Approach, however the graft takes a higher percentage in the Postauricular Approach than the Permeatal Approach.
