Modified bilateral neurovascular cheek flaps: a new technique for reconstruction of extensive upper lip defects.

The authors present a modified bilateral neurovascular cheek flap as a new technique for extensive upper lip reconstruction. The technique is modified from the bilateral neurovascular cheek flap for lower lip reconstruction described by Vatanasapt and colleagues in 1987 by designing rectangular and triangular flaps in the cheek tissues lateral to the lip defect on both the skin and the mucosal sides. This method has the advantage of preserving neurovascular structures as well as the original position of the oral commissure. Five patients are presented with acceptable surgical results. The technique is a good choice for functional reconstruction of near-total or total upper lip defects.

A Prospective Randomized, Controlled, Double-Blind Trial of the Efficacy Using Centella Cream for Scar Improvement

Objective This study was performed to evaluate the efficacy of Centella asiatica extract in cream, a preparation for the prevention of scar development of the split-thickness skin graft (STSG) donor site. Methods A prospective randomized, double-blind control study was performed to evaluate the efficacy of Centella cream in 30 patients who underwent a STSG operation. Both Centella cream and placebo were applied equally to the donor site at least 2 weeks after epithelialization was completed. A scar assessment using the Vancouver Scar Scale (VSS) was taken at 4, 8, and 12 weeks. Results Of the original 30 patients, 23 patients completed evaluation. There were significant differences in pigmentation parameter of VSS and comparative total VSS scores between 4 and 12 weeks in Centella cream group. Conclusion The effect of Centella cream on scar development of a STSG operation may be attainable in terms of better pigmentation. By means of objective measurements and longer follow-up times, Centella cream may prove to be an alternative product for hypertrophic scar amelioration.

Degree of improvement after hyperbaric oxygen therapy for compromised flap and graft: A case series

Objective: To determine the treatment outcome of hyperbaric oxygen therapy (HBOT) in compromised graft/flap. Method: A retrospective study was conducted to identify patients who had undergone ischemic compromised graft and flap and received hyperbaric oxygen therapy at Srinagarind Hospital, Faculty of Medicine, Khon Kaen University, Thailand, between 2012 and 2017. Wound improvement was the primary outcome. Results: Eleven patients with ischemic graft/flaps were enrolled in the study (9 adults; 2 children). The results showed that the treatment outcome for all patients undergoing skin flap/graft was improved. Patients classified as grade 3 and 4 (7 flaps in total) had improved wound healing without other adjunctive therapies whereas 4 patients-classified as grades 1 and 2-experienced partial wound healing and required surgical debridement with skin graft or flap reconstruction. Conclusion: In flap or graft ischemia, HBOT represented an additional medical treatment that can enhance wound healing resulting in a satisfactory treatment outcome.
