The partial excision of the larynx for invasive cancer (usually, squamous cell carcinoma), which removes the anterior soft parts of the larynx in continuity with the underlying thyroid cartilage. Hemilaryngectomy is a voice-conserving procedure that consists of dividing the thyroid cartilage at the midline and resecting—in continuity—the thyroid cartilage with the corresponding true and false vocal cords and ventricles.Indications
Up to T2 glottic tumours.
Contraindications
Subglottic extension > 10 mm anteriorly or > 5 mm posteriorly; most T3 glottic cancers; involvement of an entire vocal cord and more than one-third of the contralateral vocal cord.
