Supratracheal laryngectomy: a multi-institutional study

Area of Science:

• Otolaryngology
• Surgical Oncology
• Laryngeal Cancer Treatment

Background:

• Supratracheal laryngectomy aims to preserve laryngeal function for specific cancers.
• It is an alternative to supracricoid laryngectomy to avoid compromised margins.

Purpose of the Study:

• Evaluate the safety, viability, and margin adequacy of supratracheal laryngectomy.
• Assess outcomes for intermediate and advanced laryngeal cancer across three Brazilian institutions.

Main Methods:

• Retrospective analysis of 29 patients undergoing supratracheal laryngectomy (1997-2017).
• Classification according to European Laryngological Society standards.
• Evaluation of early/late results, survival rates, and follow-up (mean 44 months).

Main Results:

• Low rate of compromised margins (3.4%) and recurrence (13.8%).
• 5-year survival rates: Overall (82.1%), Disease-Free (83.0%), Specific (88.2%), Total Laryngectomy-Free (80.2%).
• 17.2% required total laryngectomy, with 80% success in revision procedures.

Conclusions:

• Supratracheal laryngectomy is a beneficial option for selected patients with intermediate/advanced laryngeal cancer.
• Achieves high total laryngectomy-free and specific survival rates.
• Demonstrates safety and efficacy in preserving laryngeal function while maintaining cancer control.
