Lymphadenectomy During Staging Laparotomy in Early-Stage Ovarian Cancer: a Critical Analysis of Retrospective Data.

This paper aims to assess correlation of site, size and duration of tympanic membrane perforation with hearing loss using pure tone audiogram and surgical outcome in terms of above parameters. The present study was conducted on 100 patients in Department of ENT and HNS, SMGS Hospital, Government Medical College Jammu during a time period of November 2018 to October 2019. All the patients with age 15-60 years who presented with tympanic membrane (pars tensa) perforation were included in the study. According to the size of perforation, mean pure tone threshold in group I was 20.87 ± 3.86 dB, in group II was 26.45 ± 6.08 dB and in group III was 32.6 ± 5.56 dB. The difference in hearing threshold between all the three groups was significant statistically. In terms of site, group E had maximum hearing threshold (34.67 ± 4.20 dB), followed by group B (32.71 ± 5.88 dB). Group A had the lowest hearing threshold of 24.99 ± 6.21 dB. The difference between hearing thresholds of group B perforations and group A perforations was statistically significant (p < 0.05). However, the difference between group E and group B was insignificant. This study has shown significant correlation between the size and the site of the perforation to the degree of hearing loss. The bigger the perforation, the greater the hearing loss. The central perforations were associated with more hearing loss than posterior perforations, thus refuting the hypothesis that site and size of a tympanic membrane perforation does not affect the degree of conductive hearing loss. This study did not show any correlation between duration of disease and degree of hearing loss. Surgical and audiometric results obtained in this study can be accepted as satisfactory and as expected by the literature.
