Summary
Endoscopic supraglottic laryngectomies offer excellent outcomes for selected supraglottic cancers. This minimally invasive approach provides high survival rates and preserves swallowing function, making it a viable alternative to traditional treatments.
Area of Science:
- Otolaryngology
- Surgical Oncology
- Head and Neck Surgery
Background:
- Supraglottic carcinoma presents a significant challenge in head and neck oncology.
- Traditional treatment options include radiotherapy and open neck surgery, each with potential morbidities.
- Endoscopic surgical techniques have emerged as a less invasive alternative.
Purpose of the Study:
- To evaluate the long-term efficacy and safety of endoscopic surgery for supraglottic carcinoma.
- To assess survival rates, oncological control, and functional outcomes following endoscopic partial laryngectomies.
- To compare endoscopic surgery with conventional treatment modalities.
Main Methods:
- A retrospective case series with chart review was conducted.
- Forty-five patients with supraglottic squamous cell carcinoma were treated between 1992 and 2004.
- Procedures included various types of endoscopic supraglottic laryngectomies based on the European Laryngological Society (ELS) classification.
Main Results:
- Overall survival rates were high: 93% at 3 years and 89% at 5 years.
- Postoperative complications were minimal, with two cases of hemorrhage managed conservatively.
- Patients regained swallowing function rapidly, with a mean hospitalization of 12.5 days.
Conclusions:
- Endoscopic partial laryngectomies, according to the ELS classification, are an effective treatment for selected supraglottic squamous cell carcinomas.
- This approach offers an excellent alternative to radiotherapy and open neck surgery.
- The technique demonstrates favorable oncological and functional outcomes.
