In the last decades, partial laryngectomies have emerged as surgical approaches for larynx function preservation in laryngeal cancer. Open partial laryngectomies are classified as horizontal (OPHL) or vertical (VPL), basing on the section of the thyroid cartilage. The aim of this paper was to assess similarities and differences between horizontal and vertical partial laryngectomies, with a specific focus on postoperative laryngeal anatomy and functional outcomes. OPHL has been classified by the European Laryngological Society, from supraglottic to supracricoid and supratracheal laryngectomy. VPL have been proposed by many authors, with different laryngeal reconstruction. Different laryngectomies such as Pignat’s VPL and OPHL type IIa have similar indications, including cT1-cT3 anterior laryngeal cancer. Horizontal and vertical laryngectomies modify pharyngo-laryngeal anatomy in a different way. Such alterations negatively affect laryngeal functions, especially airway protection during swallowing. In order to improve swallowing function after partial laryngectomy, it is essential to preserve the anatomy of the pharyngolaryngeal unit as much as possible.
