[Laryngeal vertical partial surgery. Surgical techniques. Oncological and functional results]

Area of Science:

• Otolaryngology
• Surgical Oncology
• Laryngeal Cancer Research

Context:

• Retrospective analysis of 467 patients with glottic carcinomas treated between 1962-1993.
• Utilized the American Joint Committee on Cancer (AJCC) staging criteria from 1988.
• 27.7% of patients presented with intermediate to advanced stage disease.

Purpose:

• To evaluate the efficacy of conservative surgical approaches for glottic carcinomas.
• To compare local control and survival rates based on surgical technique and disease stage.
• To assess functional outcomes including voice, swallowing, and respiration following treatment.

Summary:

• 5-year uncorrected actuarial survival rates were 85.6% (Stage I), 71.4% (Stage II), and 71% (Stage III).
• Local failure rates in Stages I and II were 22.4% with laryngofissure versus 10.8% with hemilaryngectomy.
• 5-year survival with voice was 75.2% with radiotherapy and 84.9% with partial laryngectomy in Stages I and II.

Impact:

• Conservative surgery, particularly hemilaryngectomy, demonstrates favorable local control and voice preservation for glottic carcinomas.
• High rates of good to fair functional outcomes (91.1% voice, 99.7% swallowing, 97.6% respiration) support these surgical methods.
• Findings contribute to optimizing treatment protocols for laryngeal cancer, balancing oncologic control with functional preservation.
