Prospective Comparative Study on Tympanoplasty Type-1 Graft Uptake Between Tragal Cartilage Perichondrium and Temporalis Fascia

Abstract

Background
Chronic Otitis Media (COM) is one of the leading causes of hearing loss in the world. Tympanoplasty is the surgical treatment to repair the defective tympanic membrane in such patients.
Aim
To compare the healing and graft uptake using temporalis fascia versus cartilage perichondrium grafts in tympanoplasty type-1.
Method
A prospective randomized comparative cohort trial was conducted in the Department of Otorhinolaryngology at a Private Medical College in South India in the year 2020. This study compared the effect of two graft materials, tragal cartilage perichondrium and temporalis fascia, in tympanoplasty and evaluated the post-operative healing, among 60 patients randomized into 2 groups.
Results
93% cases belonging to the cartilage perichondrium graft group had formation of neotympanum compared to only 53% cases in Temporalis fascia group. Statistically significant difference between the two groups in terms of formation of neotympanum suggests cartilage perichondrium was better in the aspect of healing and graft uptake.
Conclusion
Results of this study conclude that tragal cartilage perichondrium is significantly better than temporalis fascia in terms of graft uptake in cases of Type I Tympanoplasty.
