title: Indications and results of fronto-lateral laryngectomy using a combined endolaryngeal and external approach.
abstract: Patients with laryngeal anterior commissure, cord-commissure, bilateral anterior cord-commissure carcinomas (T1 and T2 N0 M0) were subjected to a new method of frontolateral laryngectomy using a combined endolaryngeal and external approach. The proposed surgical procedure allowed the removal of the anterior commissure and part of one or both vocal cords in a single unit, together with the cartilaginous framework, respecting the integrity of the superior portion of the thyroid cartilage. The internal procedure permitted an accurate delimitation of the posterior part of the laryngeal neoplasm. In particular, this was performed during suspension microlaryngoscopy using the CO(2) laser or traditional cutting tools for section of the laryngeal visceral structures to the internal surface of the thyroid cartilage. Following this, the external approach included incision of the external perichondrium along the superior edge of the thyroid cartilage and along the median line, from the incisura to the inferior edge of the thyroid cartilage. The superior opening of the larynx is made side-to-side and the epiglottis separated at the level of the superior edge of the thyroid cartilage. The ends of the section are joined together with the superior parts of the section created during the laryngeal approach. Then progressive craniocaudal detachment of the internal perichondrium is performed backwards until the endolaryngeal sections are reached and downwards to the insertion of the cord ligaments. The inferior opening of the larynx is made by a horizontal section of the cricothyroid membrane at the level of the superior edge of the cricoid cartilage. Section of the thyroid cartilage is therefore performed in a trapezoidal shape. This section involves the inferior part of the protruding corner of the thyroid cartilage. After joining the ends of the cricothyroid section with the inferior extremities of the endolaryngeal sections, the surgical specimen is removed as a single unit. The method must be used only after accurate clinical evaluation. It is mostly recommended in subjects with cord-commissure carcinomas previously treated with radiotherapy. The results obtained were extremely satisfactory both as regards survival and functional results. In all, 27/28 patients (96.4%) were free from disease. The quality of voice was satisfactory but hoarse in 30% and breathy in 70% of the patients.
