What type of surgery involves the removal of only part of the larynx?

• A. Total laryngectomy
• B. Subtotal laryngectomy
• C. Partial laryngectomy
• D. Tracheostomy

Answer: (C)

The removal of only part of the larynx is referred to as a partial laryngectomy. This surgical procedure preserves a significant portion of the larynx while removing only the affected areas, which may be necessary due to conditions such as cancer or other diseases. The goal of this surgery is to maintain as much function as possible, including aspects of voice production and airway protection.

In contrast, a total laryngectomy involves the complete removal of the larynx, resulting in loss of voice and necessitating the creation of a permanent stoma for breathing. A subtotal laryngectomy, although similar, implies the removal of a larger section of the larynx than a partial procedure, typically still preserving some laryngeal function. Tracheostomy is a surgical procedure for creating an opening in the trachea, usually for airway access, and does not involve removing any part of the larynx.

Therefore, the choice of partial laryngectomy accurately represents the surgery described in the question, focusing on the limited removal of laryngeal tissue while retaining important functions.
