Tympanic Membrane Perforation among Patients Presenting to Department of Otorhinolaryngology of a Tertiary Care Hospital: A Descriptive Cross-sectional Study.

Introduction: Intact tympanic membrane acts as a partition between the external ear and middle ear. Tympanic membrane perforation is one of the commonest causes of conductive hearing loss. Perforation size is the most important determination of hearing loss. The aim of this study was to find out the prevalence of tympanic membrane perforation among patients presenting to the otorhinolaryngology department of a tertiary care hospital. Methods: A descriptive cross-sectional study was carried out in the Department of Otorhinolaryngology and Head Neck Surgery of a tertiary care hospital from March 2021 to August 2021. Ethical approval was taken from Institutional Review Committee (Reference number: 57112021). Convenience sampling was done and data was collected from 414 patients presenting to the department. Collected data were entered, analyzed in Statistical Package for the Social Sciences version 21.0 and documented for study. Point estimate at 95% Confidence Interval was calculated along with frequency and percentage for binary data. Results: Among 414 patients, tympanic membrane perforation was seen in 100 (24.15%) (20.02-28.27 at 95% Confidence Interval). Among 100 patients with a total of 153 perforated eardrums, mild hearing loss was seen in the majority of the cases. Posterior perforation had a mean hearing loss of 40.41±5.96 dB, central had 39.09±3.13 dB, and anterior had 35.15±5.88 dB. Conclusions: Our study showed the prevalence of tympanic membrane perforation to be high when compared to other similar studies. Hearing loss was observed in all cases; the majority with mild hearing loss. The degree of hearing loss was more in larger and posterior perforation. Keywords: eardrum perforation; hearing loss; otitis media.

Success Rate of Endoscopic Sphenopalatine Artery Ligation for the Management of Refractory Posterior Epistaxis Patients in a Tertiary Care Hospital: A Descriptive Cross-sectional Study.

INTRODUCTION: Epistaxis is a common medical emergency with 5% to 15% of patients admitted for epistaxis will require surgical management as nasal packing has high failure rates. A modern endoscopic technique like Endoscopic Sphenopalatine Artery Ligation has increased in popularity for managing intractable posterior epistaxis. It has less complication and a high success rate. The study conducted to estimate the success rate of Endoscopic Sphenopalatine Artery Ligation of refractory posterior epistaxis among admitted patients in a tertiary care hospital. METHODS: This is a descriptive cross-sectional study conducted from June 2019 to June 2020 at the Department of Otorhinolaryngology, Nobel Medical College and Teaching Hospital among the patient with refractory posterior epistaxis with the help of retrospective data. A convenient sampling method was used. These patients underwent endoscopic sphenopalatine artery cauterization for recurrent/intractable posterior epistaxis. Ethical clearance was taken from the Institutional Review Board. Data were analyzed in Statistical Package for the Social Sciences. RESULTS: Out of the total patient with refractory posterior epistaxis who underwent Endoscopic Sphenopalatine Artery Ligation, the overall success rate was 39 (95.12%). Among them, 25 (60.97%) males and 16 (39.02%) females underwent endoscopic sphenopalatine artery ligation. Twenty (48.78%) of them were unilateral whilst 21 (51.21%) were bilateral disease. About 2 (4.8%) cases had re-bleeding within 48 hours which was managed conservatively. Hypertension was found to be the most common comorbid condition followed by diabetes, chronic kidney. CONCLUSIONS: From our study, we conclude that the success rate for Endoscopic Sphenopalatine Artery Ligation in a patient with refractory posterior epistaxis was high.
