Horizontal partial laryngectomy for supraglottic squamous cell carcinoma.

Area of Science:

• Otolaryngology
• Head and Neck Surgery
• Oncology

Background:

• Supraglottic squamous cell carcinoma (SCC) requires effective treatment balancing oncological control and laryngeal function.
• Horizontal supraglottic laryngectomy (HSL) is a surgical option for this condition.

Purpose of the Study:

• To evaluate the oncological outcomes and functional results of horizontal supraglottic laryngectomy (HSL) for supraglottic SCC.
• To assess factors influencing survival and recurrence.
• To compare HSL with endoscopic laser surgery.

Main Methods:

• Retrospective study of 75 patients with supraglottic SCC treated with HSL between 1981-1999.
• Analysis of tumor stage, neck disease, surgical procedures (neck dissection, adjuvant radiotherapy), and follow-up data.
• Evaluation of disease-specific survival, locoregional control, and functional outcomes (aspiration, diet, decannulation).

Main Results:

• Five-year disease-specific survival was 92%, with high locoregional (90%) and local (92.5%) control rates.
• Cartilage infiltration was associated with local control and survival.
• Postoperative aspiration occurred in 26% of patients, with most recovering function; no permanent tracheostomy was required.

Conclusions:

• Horizontal supraglottic laryngectomy (HSL) provides excellent oncological results for supraglottic SCC.
• Functional morbidity is notable, underscoring the importance of patient selection.
• Endoscopic laser surgery may offer comparable outcomes with less morbidity and warrants prospective comparison.
