It is a voice-conserving procedure which 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 ventricle.
Indications Up to T2 glottic cancers.
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.
