Abstract：
BACKGROUND: To assess the usage of contralateral infrahyoid muscles as onlay flap in prevention of pharyngo-cutaneous fistula (PCF) in total laryngectomy (TL) patients with high risk factors of PCF development.
METHODS: This study included 10 patients who suffered from advanced laryngeal carcinoma with presence of risk factors for development of PCF. We added an enforcement muscular layer during neo-pharynx wall repair, the infrahyoid muscle flap of the contralateral side of the tumour origin as an onlay muscular flap to cover the anastomotic site for healing augmentation. Patients were followed up for PCF development where the PCF incidence was calculated.
RESULTS: One patient died from congestive heart failure in the 21th post-operative day so, the actual PCF rate in TL patients with high risk factors of PCF development in our study was 11.11% (1 out of 9 cases).
CONCLUSIONS: Infrahyoid muscle flap may have a role in preventing PCF after TL in patients with high risk factors of PCF development in this case series study to be further assessed in other studies to justify its role.

摘要：
背景：评估对侧舌骨下肌作为上置式皮瓣预防咽皮瘘（PCF）的全喉切除术（TL）患者发生PCF的高危因素。
方法：本研究包括10例晚期喉癌患者，这些患者存在PCF发展的危险因素。我们在新咽壁修复期间增加了强制肌肉层，肿瘤起源对侧的舌骨下肌皮瓣，作为覆盖吻合部位的肌肉皮瓣，用于愈合增强。对患者进行PCF发展随访，并计算PCF发生率。
结果：一名患者在术后第21天死于充血性心力衰竭，在我们的研究中，具有PCF发展高风险因素的TL患者的实际PCF率为11.11％（9例中有1例）。
结论：在本病例系列研究中，舌骨下肌瓣可能在预防具有PCF发展的高风险因素的患者的TL后PCF中起作用，有待在其他研究中进一步评估以证明其作用。
