Comparison of endoscopic tympanoplasty, cartilage vs. temporalis fascia in chronic suppurative otitis media with inactive mucosal disease: A prospective randomised study.

Background: The introduction of endoscopy into middle ear has open up new opportunities for minimal invasive temporal bone surgery. The present study was planned to compare anatomical and functional outcome in patients who underwent endoscope assisted tympanoplasty using cartilage and temporalis fascia graft.

Methods: The present prospective observational randomized study was carried out in the Department of Otorhinolaryngology of a tertiary care teaching hospital of Rajasthan, India from September 2020 to July 2021. Fifty patients of age group 18-60 years, with diagnosis of chronic otitis media having inactive mucosal disease were enrolled in the study and divided into two groups viz. cartilage (group I) and temporalis fascia group (group II). Each patient postoperatively underwent otoscopic examination of ear and pure tone audiometery at 8 weeks and 3rd month. Local wound condition, graft uptake and healing and hearing were assessed and compared.

Results: Graft uptake was 92% in cartilage group and 84% in temporalis fascia group. Air conduction and air-bone gap of patients in both the groups showed significant improvement after 3 months of surgery. (p˂0.05) Regarding bone conduction, both groups had shown non-significant changes. (p > 0.05) Hearing gain was comparable on both groups which was 6.71dB in cartilage group vs. 5.9 dB in other group.

Conclusions: The present study showed that graft placement time for temporalis fascia graft was less than cartilage graft, but the difference was insignificant. Hearing improvement, graft uptake and clinical improvement were found to be statistically insignificant between both groups.
