Abstract
PURPOSE: The endoscopic approach to tympanoplasty is gaining popularity, but its adoption for the palisade tympanoplasty technique is unstudied. The aim of the present study was to evaluate the effectiveness of endoscopic cartilage palisade tympanoplasty compared to one-piece composite cartilage-perichondrium grafts for tympanic membrane closure in adult patients with subtotal perforations. METHODS: Retrospective study of 42 adult patients who underwent endoscopic tympanoplasty for a subtotal perforation in a university tertiary referral center from January 2018 to June 2019. Patients underwent transcanal tympanoplasty either with cartilage palisade grafts or with one-piece composite cartilage-perichondrium grafts. Both techniques were compared for graft take rate and audiometric results. RESULTS: Twenty palisade and 22 single-piece tympanoplasties were analyzed. No statistically significant differences between groups were found in terms of tympanic membrane closure (85% vs. 86.3%, p = 0.5) or hearing improvement. CONCLUSION: The results of the present study suggest that similar results can be obtained with palisade cartilage grafts compared to the one-piece composite cartilage-perichondrium technique for endoscopic tympanic membrane closure. Further studies with long-term results will be needed to confirm these findings.
