Efficacy of composite perichondrial–chondral graft in type 1 tympanoplasty a comparative study

Abstract

Introduction: Temporalis fascia is the most commonly used material for tympanic membrane reconstruction, followed by perichondrial graft. Objective: To compare the efficacy of cartilage graft versus temporalis fascia graft. Study Design is Randomised prospective study in ENT department of tertiary care hospital (NRI medical college and general hospital) Material and Methods: A sample size of 60 patients used, who were randomly divided into two groups-Group A (Perichondrial-chondral graft) and Group B (Temporalis fascia graft). They were subjected to a detailed history and clinical examination. After surgery, they were followed-up at one month, three months, and six months to check for graft uptake and hearing assessment byPure Tone Audiometry. Results: It was observed that in Group A 100% (30) of the patients achieved complete closure of tympanic membrane by the end of the first month, and it remained unchanged till the end of 6 months. In Group B, 96.6% (29) patients achieved complete closure by the end of the 1st month, and it reduced to 93.3% (28) at the end of six months.Conclusions: Although there is no statistical difference in graft uptake and hearing improvement between the groups, the graft uptake and hearing results for perichondrial-chondral graft in comparison with temporalis fascia grafts are slightly better.
