The surgical approach to the hypopharynx by lateral pharyngotomy as described by Trotter has found widespread use in management of supraglottic carcinoma. A similar but more conservative approach may be employed for removal of cysts and benign or well-encapsulated neoplasms of the epiglottis and supraglottic space. We call this approach a supero-lateral thyrotomy, to differentiate it from the classic lateral pharyngotomy. Surgery consists of subperichondrial resection of the superior half of the ipsilateral thyroid cartilage with preservation of internal lining and superior laryngeal nerve. The lesion may then be enucleated or resected, and the defect, if any exists, closed with overlying mucosa and the flap of preserved perichondrium. The technique has been employed in cases of paraganglioma, haemangiopericytoma and saccular cysts.
正如特罗特所描述的，经外侧咽切开术治疗下咽的手术方法已广泛应用于声门上癌的治疗。对于会厌和声门上间隙的囊肿、良性或包膜完整的肿瘤，可采用类似但更为保守的方法进行切除。我们将这种方法称为上外侧甲状腺切开术，以区别于经典的外侧咽切开术。手术包括在保留内衬和喉上神经的情况下，对同侧甲状软骨上半部分进行软骨膜下切除。然后可以将病变摘除或切除，如果存在缺损，则用覆盖的黏膜和保留的软骨膜瓣进行封闭。该技术已应用于副神经节瘤、血管外皮细胞瘤和囊状囊肿的病例。
