Hemicricolaryngopharyngectomy was performed for anterior pyriform sinus carcinomas with preservation of voice and swallowing. The surgical specimen includes the homolateral half of the hypopharynx, larynx, and cricoid ring. The pharynx is reconstructed with a pectoralis myocutaneous flap, a deltopectoral flap, skin or dermal graft. A semirigid mucosa-lined speech tube is created by folding in the remaining half of the larynx. This tube, which is 4 to 5 mm in diameter, serves as a phonatory structure. Speech is produced by occluding the stoma with the finger and shunting air via this dynamic pseudolarynx. Patients maintain a permanent tracheostomy. Our experience includes 14 cases with up to 4-year follow-up.
对于梨状窝前部癌，在保留声音和吞咽功能的情况下进行半环状喉咽切除术。手术标本包括下咽、喉和环状软骨的同侧半侧。咽部用胸大肌肌皮瓣、三角肌胸大肌皮瓣、皮肤或真皮移植物进行重建。通过将剩余的半侧喉折叠形成一个半刚性的内衬黏膜的语音管。该管直径为4至5毫米，作为发声结构。用手指堵住造口并通过这个动态假喉分流空气来产生语音。患者维持永久性气管造口。我们的经验包括14例患者，随访时间长达4年。
