“…As previously stated, some commissural flap designs allow direct closure [20,45,48,[51][52][53][54]; in such cases, resurfacing is achieved through flap positioning and defatting [71], which may compromise flap viability in case of tight suturing [14], as well as leaving the residual defects open [72]. Another option is to prevent cutaneous tissue shortages by performing preoperative tissue expansion, using either an external fixator [73][74][75][76] or subcutaneous devices [77,78]; however, despite satisfactory outcomes reported by different authors, the inherent morbidity of these techniques have limited their use to complex and complicated cases such as Apert's hand [76].…”
