Open Partial Horizontal Laryngectomy Type I (OPHL 1)
摘要
The open partial supraglottic laryngectomy (OPHL I according to the ELS classification) was firstly described in 1947 but still represents an effective surgical procedure for low to selected high stage supraglottic laryngeal cancer and limited base of tongue tumors. Resection might be extended to one arytenoid, to the medial wall of one pyriform sinus, or to the base of tongue according to tumor extension. When adequately performed, OPHL I provides good oncological outcomes together with phonatory and swallowing ones. The present section describes the step-by-step surgical procedure.
