Background: Chronic Otitis Media(COM) affects 65-330 million globally, 60% of whom have hearing impairment.[1] It presents as recurrent ear discharge through a perforated tympanic membrane. The perforation mostlystemsfrom middle ear infections, apart from trauma and iatrogenic factors.[2]Persistent infections lead to chronic perforation, necessitating tympanoplasty. Type-1 tympanoplastyis repair of tympanic membrane perforation, utilizing Temporalis Fascia(TF) grafts.The limited studies comparing dry versus wet TF graftsprompted us to pursue this study. Objectives: Comparison ofhearing improvement and graft uptake and placement time between the two groups. Materials &methods: Sixty blinded participants with COM were randomized into two groups one received the dry and the other received the wetTF graft.Graft placement time, pre and post-operative audiometry, and graft uptake were assessed.Descriptive statistics was used for categorical and continuous data. Chi-square and Mann-Whitney U tests were done to compare between groups. Results: Our findings were similar between the dry graft and wet graft groups' concerning hearing loss improvement (mean±SD= 14.33±5.42 dB and 14.17±5.09 dB, respectively,p<0.94) and graft uptake [27(90%) and 26(86.7%) participants, respectively, p<0.69].On average the dry graft placements were completed earlier (mean±SD=5.77±1.07minutes) than the wet graft placement(mean±SD=10.47±1.48 minutes). This difference was significant(p<0.001). Both groups experienced no postoperative complications. Conclusion: Based on our study and existing research, we conclude that dry and wet TF grafts produce comparable hearing improvement and graft uptake. Dry grafting offers shorter placement times without compromising outcomes, providing surgeons with anexpeditious approach. |
