Early‐stage supraglottic cancers that involve the false cord, aryepiglottic fold and even a single arytenoid—but leave both true vocal cords mobile—are best managed with a horizontal supraglottic (partial) laryngectomy, which removes the supraglottic structures while preserving the glottis and normal voice and airway function; vertical hemilaryngectomy targets glottic disease, and total laryngectomy or primary chemoradiation are reserved for more advanced or non-resectable lesions [Dong, 1998, PMID 10921017; Bocca, 1986, PMID 3619281; Gehanno, 1996, PMID 8902561].
