Throat cancer operation

Laryngectomy is surgery to remove all or part of the larynx, or voice box. Total laryngectomy is used for advanced or recurrent cancer of the voice box. Partial laryngectomy aims to preserve some of its function in selected patients. An important distinction is whether surgery is the first treatment or a salvage treatment, meaning surgery after an earlier treatment has failed. These are different treatment situations, not interchangeable versions of the same choice.

For some people with T3 laryngeal cancer, treatment options include total laryngectomy or treatment intended to preserve the voice box, using radiotherapy alone or together with chemotherapy. The choice balances cancer control, function and personal preferences. Organ-preserving treatment is suitable for only a subset of patients. For more advanced T4 tumours, the evidence favours total laryngectomy over non-surgical treatment.

The evidence for T3 cancer is not uniform: a 2024 review found no difference in mortality between surgical and non-surgical treatment, whereas a 2026 review reported modest survival advantages with total laryngectomy. This comparison does not establish one best treatment for every patient.

A separate option applies to carefully selected people whose early cancer of the vocal-cord area has returned after radiotherapy: salvage partial laryngectomy may preserve voice-box function while leaving total laryngectomy as a further option if needed.

In a 2026 analysis of 13 studies involving 2,704 patients, 1,791 had total laryngectomy as their initial treatment and 913 had salvage total laryngectomy. Survival was higher in the initial-surgery group at one, two and three years. At three years, the odds of being alive were 1.64 times those in the salvage group, with a confidence interval of 1.10 to 2.47. This is a comparison of odds between treatment groups, not an individual survival percentage or proof that choosing surgery first causes that advantage.

The same analysis found less swallowing difficulty after initial surgery, but no statistically significant difference in speech function between the groups. These findings concern initial versus salvage total laryngectomy; they do not directly compare surgery with radiotherapy or chemotherapy.

After total laryngectomy, a fistula can develop: an abnormal connection between the throat and the skin of the neck. A persistent fistula may need another operation. Reinforcement with tissue that has its own blood supply is an option in selected high-risk cases, including salvage surgery.

Other complications include swallowing difficulty and narrowing of the food passage. An underactive thyroid can also develop after laryngectomy. It is associated with removal of half the thyroid, radiotherapy and surgery to remove lymph nodes in the neck, and with a higher risk of wound complications.

For people using a voice prosthesis after total laryngectomy, leakage around the device is another possible problem. Injections to add volume to the surrounding tissue can be used to treat this leakage, but the benefit can be temporary and the treatment needs to be individualised.

Recovery planning includes improving nutrition before surgery and supporting feeding through a tube after surgery. Follow-up includes monitoring for fistula formation and treating a persistent fistula.

Assessment of swallowing after laryngectomy includes your medical and swallowing history, questions about your experience, and observation of swallowing tasks. This helps guide further assessment and referral. Thyroid-function testing before and after surgery is also part of monitoring, particularly when treatment puts thyroid function at risk.
