ObjectiveManagement of anterior perforations of tympanic membrane is a surgical challenge. The objective of this study is to analyse and compare the results of composite cartilage perichondrium island (CCPI) graft and temporalis fascia graft by endoscopic technique in anterior quadrant perforations.MethodsA prospective study was conducted in a tertiary care centre from 2012–16. A total of 187 ear drums(n) in 168 patients with perforations involving anterior quadrant were included in the study. All the patients were operated completely by endoscopic technique. Tragal Composite cartilage perichondrium island (CCPI) graft was used in 87 ears and temporalis fascia in 100. Each group was categorised into A and B depending on perforation size. The outcome parameters assessed include graft success with regard to perforation size, pre- and postoperative ABG, mean improvement in ABG, ABG closure ratio and graft medialisation/lateralisation status.ResultsCartilage group had 91.95% (80/87) success rate overall, while fascia had 79% (79/100). In category 1, the success rate for cartilage and temporalis fascia were 89.6% (26/29) and 68.9% (20/29) respectively (p=0.51788). In category 2, the success rates were 93.1% (54/58) and 83.1% (59/71) respectively (p=0.86356). The mean improvement in ABG for both groups were 17.52±3.84dB and 15.26±5.56dB respectively (p=0.04). ABG closure ratio for both the groups were 62.84±11.87 % and 53.6±19.6 % respectively (p=0.0008).ConclusionEndoscopic composite cartilage perichondrium island graft is an effective technique in managing perforations of anterior quadrant barring the expertise required for endoscopic ear surgeries.
