Feasibility, comparability and outcomes of three acquainted facial island flaps for periorbital defects reconstruction.

Abstract

Severe coloboma of ocular malignant neoplasms post-resection poses a reconstructive challenge to surgeons. To compare the practicability, manipulability and outcomes of temporal (myocutaneous) flaps (TFs), forehead (supratrochlear artery/supraorbital artery) flaps (FFs) and buccal (facial artery) flaps (BFs) for periorbital defects reconstruction, a retrospective case series was conducted and evaluated between March 2014 and March 2021. Patient demographics and clinical parameters including age, gender, pathological diagnosis, operative methods, flap selection, operation time, aesthetic satisfaction and follow-up period were collected. The differences in complications were compared and assessed of the three flaps, including flap survival, venous congestion and donor site healing. Totally, 68 patients who underwent periorbital reconstructive operations because of common ocular malignant tumours were reviewed in this study. As for aesthetic satisfaction, a score more than "moderately dissatisfied" was obtained in 21 patients with TFs (95.5%), and of which the scores in FFs group were 12 cases (60%) and 16 cases with BFs reconstruction (61.5%) (P< .05). Severe microvascular complications underwent re-exploration operation occurred in one patient with FFs (1.5%) (P> .05). Notable flap necrosis was observed in two patients with BFs repair (2.9%) and in one case with FFs repair (1.5%), with no statistical difference between the three flap selections (P> .05). Moderate venous congestion occurred in one patient with TFs (1.5%), which was fully meliorated non-surgically. The three familiar facial island flaps are considered as minor trauma and time-saving process for reconstructing the extensive periorbital defects with comparable ranks of complications.
