Carbon dioxide laser microsurgery for early supraglottic carcinoma

Area of Science:

• Otolaryngology
• Surgical Oncology
• Laser Medicine

Background:

• Early supraglottic carcinoma requires effective treatment to ensure tumor control while preserving laryngeal function.
• Traditional open supraglottic laryngectomy can result in significant functional deficits, including aspiration.

Purpose of the Study:

• To evaluate the efficacy and functional outcomes of primary carbon dioxide laser microsurgery for early supraglottic carcinoma.
• To compare transoral laser microsurgery results with historical data from open supraglottic laryngectomy.

Main Methods:

• Retrospective analysis of 48 untreated patients with early supraglottic carcinoma (Stage I and II) treated between 1979 and 1994.
• Primary treatment involved carbon dioxide laser microsurgery with the goal of complete tumor removal and laryngeal structure preservation.
• Follow-up included assessment of local control, recurrence-free survival, overall survival, and functional outcomes (voice preservation, aspiration).

Main Results:

• High 5-year local control rates: 100% for pT1 and 89% for pT2 cases.
• Ultimate local control with voice preservation was 97% for pT2 carcinomas.
• 3-year recurrence-free and overall survival rates were 87% and 85%, respectively; 5-year rates were 83% and 76%.

Conclusions:

• Transoral laser microsurgery provides local control and survival rates comparable to open supraglottic laryngectomy for early supraglottic carcinoma.
• This technique offers superior functional results, notably the absence of clinically relevant aspiration.
• Laser microsurgery is a viable and effective organ-preserving option for selected patients with early supraglottic tumors.
