“…18,19 The treatment of FS consists of oral and topical medications, radiotherapy, surgery, and botulinum toxin type A injection, although fortunately only the minority of these patients require treatment. [20][21][22][23][24][25][26][27][28][29][30] In addition, the efficacy of different procedures to prevent FS, such as thick skin flap elevation, subsuperficial muscular aponeurotic system (SMAS) dissection, placement of different barriers (dermofat graft, lyophilized dura, polyglactin, acellular dermal matrix) and sternocleidomastoid muscle, platysmal muscle, temporoparietal fascia, or SMAS interposition techniques were evaluated in previous studies. [30][31][32][33][34][35][36][37][38][39] In previous studies that aimed to assess the association between skin flap thickness and FS, the skin thickness was determined subjectively and defined in accord with the depth of dissection, such as below the level of hair follicules, sub-SMAS, or subcutaneous.…”
