Near‐Total Laryngectomy in Advanced Laryngeal and Pyriform Cancers

OBJECTIVE: To demonstrate the oncologic and physiological safety of near-total laryngectomy (NTL), its success in voice conservation, and its versatility for use in extensive resections that necessitate pharyngoplasty, and even in post-radiation recurrences. STUDY: In this study of 137 cases of NTL for cancer of the larynx (45 cases) and pyriform (92 cases), 86.9% were stage T3/T4 and 60.6% were N+. A total of 8.8% had extended pharyngeal resections necessitating patch pharyngoplasty (ENTLP). In 10.9% cases, NTL was used as salvage of post-radiation failures. Concurrent neck dissection was performed in 99 cases. RESULTS: A total of 70.1% was alive and disease-free at the last follow-up ranging from 12 months to 104 months (median, 35 mo). A total of 7.3% had local/locoregional recurrences and 11.7% had purely regional recurrences. The local control rate for post-radiation salvage with NTL was 93.3%. A total of 88.6% developed communicable speech, and the speech success rate was 100% in 12 cases of ENTLP. Complications included major wound dehiscence with total shunt breakdown in 2 cases (1.5%), pharyngeal leak requiring surgical intervention in 7 cases (3.6%), significant aspiration through the shunt necessitating completion laryngectomy in 1 case (0.7%), and complete shunt stenosis in 9 cases (6.6%). CONCLUSION: The study shows that NTL is an oncologically safe voice conservation procedure in advanced, lateralized laryngeal and pyriform cancers treated not only per primum, but also in carefully selected post-radiation failures. It has a high success rate of speech development even in those cases requiring extensive pharyngeal resections. Major complications were acceptably low.
