In simple words: The surgeon removes part of the voice box, including the area where the vocal cords join and one vocal cord. A temporary opening is made in the windpipe to help with breathing during surgery.

This procedure involves the partial removal of the larynx (voice box), specifically the anterior commissure (where the vocal cords meet), a vocal cord, and underlying cartilage. It typically includes a tracheostomy to maintain an airway during surgery. After the tracheostomy, an incision is made in the neck muscles to access the larynx. The diseased tissue, including the anterior commissure, a vocal cord, and potentially the arytenoids (cartilage structures at the back of the vocal cords), is removed. The incision is then closed with sutures.

Example 1: A patient with early-stage glottic cancer involving the anterior commissure and one vocal cord undergoes an antero-latero-vertical hemilaryngectomy., A patient with a localized tumor affecting the anterior portion of the larynx undergoes this procedure to remove the cancerous tissue while preserving some voice function., Following radiation therapy failure, a patient with a persistent lesion in the antero-lateral-vertical region of the larynx undergoes this partial laryngectomy.

Documentation should include operative notes detailing the extent of the resection, the tracheostomy procedure, and any reconstructive techniques used. Pathology reports confirming the diagnosis and margins are also essential.
