Submental flap for reconstruction of anterior skull base, orbital, and high facial defects

PURPOSE: Large anterior skull base, orbital, and high facial defects can present a challenging reconstructive problem. Limited data exists in the literature on the use of a submental flap for reconstructing such defects. We aimed to describe the feasibility, success, and advantages of using variations of the submental flap for reconstruction of anterior skull base, orbital, and high facial defects. MATERIALS & METHODS: Outcomes measured included flap method, flap survival, flap size, reconstructive site complications, donor site complications, and length of hospital stay. RESULTS: Nine patients were identified that underwent submental flap reconstruction of anterior skull base, orbital, or high facial soft tissue defects. There were 5 pedicled, 2 hybridized, and 2 free submental flap reconstructions. Flap survival was 100%. One flap required leech therapy for early post-operative venous congestion. Average flap skin paddle size was 63.7 cm2. Average length of hospital stay was 7.3 days. No complications from the donor site were reported. CONCLUSIONS: Different variations on the submental flap are viable options for reconstruction of high defects in the head and neck. Such flaps have a number of unique qualities that are suitable for reconstruction of anterior skull base, orbital, and high facial defects.

In nine patients, submental flap variants (pedicled, hybridized, free) for anterior skull base, orbital and high facial defects achieved 100% flap survival with no donor-site complications; one flap required leech therapy for venous congestion.
