Introduction Based on the cross-innervation of buccal and marginal mandibular branches of the facial nerve, oblique elastic musculomucosal flaps (OEMMFs) can be harvested and used for continent neo-commissure and modiolus reconstructions. The composite pericommissural defects can then be reconstructed with double cutaneous paddles in Pacman-style free radial forearm flap (PFRFF). This novel single-stage continent reconstruction of composite post-excisional commissure and pericommissural (CPECPC) defects is evaluated in this study.
Patients and Methods This retrospective cohort study was conducted from April 2016 to March 2019. Forty-two patients underwent this type of reconstruction using a combination of PFRFF and OEMMF for the CPECPC defects. They were followed for an average period of 11.5 months. At the end of the follow-up period, they were assessed using the objective institutional scoring system by two independent observers and final score was computed for each patient.
Results The average score obtained at the end of the follow-up period was 11.5 (p = 0.035) using the institutional assessment scoring system, which evaluated both the overall aesthesis and function of the neo-commissure and modiolus.
Conclusions The combination of OEMMF and PFRRF for the single-stage reconstruction of CPECPC defects is a useful addendum for re-establishing the aesthesis and continence at the reconstructed site.
Objectives Arteriovenous malformations (AVMs) are high-flow, aggressive lesions that cause systemic effects and may pose a risk to life. These lesions are difficult to treat as they have a tendency to recur aggressively after excision or embolization. So, it requires a regulating free flap with robust vascular flow averting the postexcisional ischemia-induced collateralization, parasitization, and recruitment of neovessels from the surrounding mesenchyme—a phenomenon precipitating and perpetuating the recurrence of AVM.
Materials and Methods Sixteen patients (12 males and 4 females) with AVMs Schobinger type 4 involving face were treated from March 2015 to March 2021 with various free flaps: three free rectus abdominis flaps, one free radial forearm flap, and twelve free anterolateral thigh flaps were used for reconstruction following the wide local excision of Schobinger type 4 facial AVM. The records of these patients were analyzed retrospectively. The average follow-up period was 18.5 months. The functional and aesthetic outcomes were analyzed with institutional assessment scores.
Results The average size of the flap harvested was 113.43 cm2. Fourteen patients (87.5%) had good-to-excellent score (p = 0.035) with institutional aesthetic and functional assessment system. The remaining two patients (12.5%) had only fair results. There was no recurrence (0%) in the free flap group versus 64% recurrence in the pedicled flap and skin grafting groups (p = 0.035).
Conclusion Free flaps with their robust and homogenized blood supply provide a good avenue for void filling and an excellent regulating effect in inhibiting any locoregional recurrences of AVMs
