Abstract
Objective: To evaluate perforation of an air-bone gap closure success using fascia-cartilage composite graft in endoscopic Trans canal tympanoplasty.
 Study Design: Randomized Control Trial (Clinical Trials.gov Identifier: NCT04945811)
 Place and Duration of Study: ENT Department Combined Military Hospital, Quetta Pakistan, from Apr 2020 to May 2021
 Methodology: One hundred and thirty-three cases of chronic Suppurative otitis media fulfilling the selection criteria were operated upon, and an endoscopic fascia-cartilage composite graft was used. A successful outcome in terms of perforation closure and air-bone gap closure was evaluated in all patients.
 Results: In the 138 patients operated, complete fascia-cartilage composite graft uptake was achieved in 129 (93.5%) patients. Nine (6.5%) patients had graft failure. The pre-operative mean air-bone gap was 36.49 ± 4.61 decibels, and the postoperative mean air-bone gap was 12.57 ± 5.09 decibels. This improvement was found to be significant, with the p-value < 0.001.
 Conclusion: Endoscopic per-meatal fascia-cartilage composite grafting has a high graft uptake and air-bone gap closure percentage in chronic Suppurative otitis media cases.
