유리 전외측 대퇴부 피판과 유리 요측 전박 피판을 이용한 설재건 시 공여부 및 기능적 결과 비교

Abstract

Purpose: The purpose of this study is to evaluate the functional outcome and donor site morbidity of anterolateral thigh free flap(ALT) compared to Radial forearm free flap(RFFF) for the reconstruction of partial glossectomy defect.Methods: 5 ALT free flap (group I) were attempted for partial glossectomy patients. We compared patients undergone ALT flap with those(n=11) of similar size defect reconstructed with RFFF (Group II). Rating scales for articulation and swallowing function were applied and donor site morbidity have been evaluated.Results: The scales for speech function showed no difference between the two groups (average score; group I-6.4, group II-6.45). Swallowing function also showed no difference between the two groups(average score; Group I-6.6, Group II-6.27). ALT group had one patient with donor site morbidity(numbness). All of the RFFF patients(11/11) complained and suffered from hypertrophic scar, retraction, numbness or hyperpigmentation on forearm donor site. Based on our study, ALT free flap is comparable to that of RFFF in terms of functional assessment in tongue reconstruction.Conclusion: Considering the donor site morbidity, ALT flap is to be valuable to reconstruct partial glossectomy defect.
