후이부 피하조직-측두두정근막피판을 이용한 유양동절제술후 생긴 이후부 피부결손의 복구

Abstract

Severe postmastoidectomy wound infection infrequently leaves large skin and soft tissue defects over postauricular area, which is ususlly quite difficult to repair by primary closure. Using “Retroauricular subcutaneous tissue-temporoparietal fascia flap” whose main vessel of blood supply is posterior auricular artery, such defects could be successfully repaired in two patients who underwent revision mastoidectomy. In this axial pattern local scalp flap, distal semilunar potion of the flap had only subcutaneous tissue and temporoparietal fascia, which was slid into the postauricular defect area. This new flap approach can be useful in repairing postauricular skin and soft tissue defects following radical mastoidectomy.
