Vertico-frontolateral laryngectomy (hemilaryngectomy). Indications, technique, and results.

The hemilaryngectomy procedure includes the entire hemithyroid cartilage with the extent of the cartilage cut beyond the midline determined by endoscopy and cord cut determined after anterolateral pharyngotomy to minimize or maximize the procedure according to tumor size. Hypopharyngeal or piriform sinus mucosa was used to reconstruct the resected hemilarynx. There were 56 male subjects and one female subject. The mean age was 59 years. All had squamous cell carcinoma. There were 25 T1 lesions. Their 3-, 5-, and 10-year adjusted survival rate was 100%. The average survival in years was 6.6. Five T1 tumors were radiation failures. There were 27 T2 lesions. Their three-year adjusted survival rate was 100%; five-year rate, 94.1%; and ten-year rate, 84.7%. The average survival in years was 5.48. There were five T3 lesions. Their 3-, 5-, and 10-year adjusted survival rate was 100%. The average survival in years was 8.4.
