Laryngofissure is a rare and specialized open surgical procedure used when the larynx must be opened through the front (midline) to access deep or complex problems. It may be used to remove large benign or malignant tumors, correct congenital anomalies, or treat significant trauma. This approach gives the surgeon a direct view and full access to the vocal cords and supporting structures.

Under general anesthesia, a vertical incision is made in the front of the neck, and the thyroid cartilage is split apart to open the larynx. After addressing the underlying issue — such as tumor removal or reconstruction — the larynx is carefully closed and often stabilized with sutures or a stent. Recovery involves a hospital stay, possible temporary tracheostomy, and strict voice rest. The voice may change after surgery depending on the area treated. Risks include infection, scarring, vocal changes, or airway complications, and patients are monitored closely with follow-up scopes and speech therapy as needed.
