Background and Objectives : The ideal flap for head and neck reconstruction should be pliable,have sufficiently long pedicle and minimize donor defects. Anterolateral thigh free flap(ALTFF) and radial forearm free flap (RFFF) have been the workhorse flaps for head and neckreconstruction. However, ALTFF is too bulky and RFFF leaves a conspicuous scar on the donnersite. Medial sural artery perforator free flap (MSAPFF) is a possible alternative, which hasthe benefit of thin RFFF and low donor site morbidity of ALTFF. Here, we evaluated for thefirst time the usefulness of MSAPF for head and neck reconstruction in Korean patients.
Subjects and Method : We carried out a retrospective study of patients who underwent MSAPFFfor head and neck reconstruction from October 2018 to July 2019 by retrieving their data fromelectronic medical records. Patient characteristics, flap characteristics, surgical outcomes, andcomplications of donor sites were analyzed.
Results : Eight patients underwent MSAPFF reconstruction after head and neck surgery. Therecipient sites were the following: the floor of the mouth, palate, tongue, the base of the tongueand nasolabial fold. The average median flap size was 34.1 cm2 (range 17.5-50 cm2), length 7.1cm (5.0-10.0 cm), width 4.7 cm (range 3.5-5.0 cm), and pedicle length 9.2 cm (range 8-10 cm).
There was one flap failure because of pedicle arterial insufficiency. All donor sites were closedprimarily without any complication.
Conclusion : Based on the findings of this study, MSAPFF may be a new workhorse flap becauseit has thin, pliable tissue with low donor-site morbidity for head and neck reconstruction.
