AIM: This study aimed to assess the anatomical and functional success rate of Butterfly Cartilage Inlay Graft myringoplasties done at Chris Hani Baragwanath Academic Hospital using an oto-endoscope. Size of perforation was assessed as a possible predictor of success. METHODS: The study comprised of a retrospective review of all records from the ENT Department at Chris Hani Baragwanath Academic Hospital of all patients who underwent BCIG myringoplasty from January 2009 to December 2013. 85 of the 160 patients who had BCIG’s at CHBAH met the inclusion criteria for this study. Data was collected on a data collection sheet and analysed using standard statistical methods. RESULTS: 85 patients were included in the study of ages 5 years – 67 years with a mean age (SD) of 19,2 years (16,3). 61% were children (<13 years), 39% adults (14 – 49 years) and only 6% were >50 years. There were 30 (35%) Female patients and 55 (65%) Male patients. The data presented in this study show an anatomical success rate of 90,6% for Butterfly Cartilage Inlay Grafts at Chris Hani Baragwanath Academic Hospital. The anatomical success rate of this study is equal to the success rates reported in the literature for the same procedure. 87% of patients experienced hearing improvement post operatively. The average hearing improvement in this study post Butterfly Cartilage Inlay Graft is 15dB. Finally, perforation size does not influence both anatomical and functional success rates in this study. CONCLUSION: Endoscopic BCIGs performed at Chris Hani Baragwanath Academic Hospital, for small, medium and large perforations, show anatomical and functional success rates similar to those reported in the literature, performed with both microscope and endoscope. Size of perforation is not a predictor of anatomical and functional success for this procedure.
