Medical necessity for an anterovertical hemilaryngectomy is established when there is a confirmed diagnosis of a laryngeal lesion requiring surgical intervention, with the extent of the lesion appropriate for this procedure.The procedure must be deemed medically necessary by the treating physician and supported by appropriate clinical documentation.Payer specific guidelines apply.

The otolaryngologist (ENT surgeon) is primarily responsible for performing this surgery. The anesthesiologist will manage the anesthesia.Pre- and post-operative care may involve other medical professionals, depending on the patient’s needs.The surgeon performs the tracheostomy prior to the laryngectomy.

In simple words: This surgery removes part of the voice box.A small tube is inserted into the windpipe to help breathing during the operation.The surgeon then makes a cut in the neck to remove the diseased area of the voice box, and closes the incision.

Anterovertical hemilaryngectomy involves the surgical removal of a portion of the larynx, specifically the anterior commissure (where the vocal cords meet) and usually a section of the vocal cord.The procedure typically includes a preliminary tracheostomy to facilitate breathing during surgery.After creating a tracheostomy incision, an incision is made through the neck muscles to access the larynx. The diseased tissue is excised, and the incision is closed with sutures.

Example 1: A 60-year-old male presents with a history of progressive hoarseness, dysphagia, and a palpable neck mass. A biopsy confirms squamous cell carcinoma localized to the anterior commissure.An anterovertical hemilaryngectomy is performed., A 55-year-old female with a history of smoking presents with dyspnea and stridor.Imaging reveals a vocal cord mass.An anterovertical hemilaryngectomy with tracheostomy is performed to resect the tumor. , A 70-year-old male with a history of recurrent respiratory papillomatosis undergoes an anterovertical hemilaryngectomy to remove recurrent lesions in the anterior larynx.

Detailed medical history, including symptoms and duration, imaging studies (e.g., CT scan, MRI) showing the extent of the tumor, pathology report confirming the diagnosis, operative report with specifics of the procedure and tissue removed, and post-operative recovery notes.
