Endoscopic supraglottic laryngectomy with postoperative irradiation

Area of Science:

• Otolaryngology
• Surgical Oncology
• Head and Neck Cancer Research

Background:

• Squamous cell carcinoma of the supraglottic larynx presents a significant challenge in head and neck oncology.
• Endoscopic laser surgery offers a less invasive alternative to traditional laryngectomy.
• Evaluating oncologic and functional outcomes is crucial for treatment optimization.

Purpose of the Study:

• To assess the efficacy of endoscopic carbon dioxide laser supraglottic laryngectomy for T2 infiltrating squamous cell carcinoma.
• To evaluate primary tumor control and regional lymph node metastasis management.
• To determine functional outcomes, including swallowing and need for long-term feeding or airway support.

Main Methods:

• Retrospective review of 68 patients with supraglottic squamous cell carcinoma treated between 1987 and 1999.
• Selection of 46 clinically staged T2 patients for endoscopic carbon dioxide laser supraglottic laryngectomy.
• Analysis of outcomes for patients receiving combined surgery and postoperative irradiation versus surgery alone.

Main Results:

• Excellent primary site control (97% in combined therapy, 100% in surgery-only).
• High regional control rates (96% for N0, 91% for N+).
• Low functional morbidity: 3% gastrostomy dependency, 0% tracheotomy dependency, 5% aspiration pneumonia, and rapid return to independent swallowing.

Conclusions:

• Endoscopic carbon dioxide laser supraglottic laryngectomy is a safe and effective treatment for T2 infiltrating squamous cell carcinoma.
• Combined therapy demonstrates high rates of oncologic control with preserved laryngeal function.
• This approach facilitates functional recovery, minimizing long-term dependency on gastrostomy or tracheotomy.
