Interposition Technique for Septal Perforation Using a Composite Graft Made Up of Allograft Dermal Matrix and Autologous Cartilage

Background and Objectives Interposition using acellular allograft between perforated septal flaps is a popular procedure among surgeons because of its usefulness. However, dermal matrix itself tends to become infected sometimes, can easily undergo necrosis or be displaced from the implanted site. Here, authors would like introduce newly devised interposition graft made up cartilage, which easy manipulate fixed in desired position.Subjects Method We performed retrospective chart review January 2018 August 2020. A total 12 patients with perforation who received surgical treatment were included this study. Acellular human (MegaDerm® ; L&C Bio) was used as an piled by autologous it positioned mucoperichondrial via endonasal approach.Results The most common etiology previous surgery (n=8); one case, repeated electrocauterization due frequent epistaxis; not verified for three cases. All cases achieved result complete closure. on follow-up inquiry reported marked improvements visual analogue scale score (mean value, 4.1 1) Nasal Obstruction Symptom Evaluation 7.3 1.8).Conclusion Composite cartilage successful results without having fix graft. It alternative technique treat inexperienced limited operation field.
