Abstract

Objective: To assess the feasibility of utilizing the keystone design perforator island flap (KDPIF) for the repair of small to medium-sized defects in the buccal mucosa and floor of mouth (cT1-2 stage tumor).

Study design: We conducted a retrospective analysis of eight patients who underwent KDPIF to address oral defects at the Affiliated Hospital of Qingdao University between June 2021 and September 2022. Patient information, including medical history, defect site, flap size, operative time, hospital stay, complications, and postoperative recovery of oral function, was comprehensively evaluated.

Results: Eight patients (6 females and 2 males) underwent reconstruction using KDPIF. The mean operation time was 58.5 minutes (55-63 minutes), with an average length of stay of 3.5 days (3-5 days). None of the 8 cases (100%) exhibited flap splitting necrosis or infection. Moreover, no scar contracture was observed, and oral functions, including the degree of opening, type of opening, tongue mobility, speech function, and swallowing function, were successfully restored. One patient (12.5%) experienced bleeding from the incision on the first postoperative day, but following compression, hemostasis was achieved, and the incision healed well.

Conclusions: KDPIF demonstrates technical feasibility and suitability for repairing small to medium-sized buccal mucosa and floor of mouth defects (cT1-2).
