Summary
Partial supraglottic laryngectomy offers acceptable functional results for limited tongue base cancers. This surgical approach may preserve laryngeal function for select patients with early-stage tumors.
Area of Science:
- Otolaryngology
- Surgical Oncology
- Head and Neck Cancer
Background:
- Tongue base cancers near the epiglottis often necessitate extensive laryngeal resection.
- A novel partial supraglottic laryngectomy technique was developed for tumors with limited epiglottic invasion.
Purpose of the Study:
- To evaluate the efficacy and functional outcomes of a partial supraglottic laryngectomy for tongue base cancer.
Main Methods:
- A cohort of five patients with tongue base carcinoma underwent partial supraglottic laryngectomy.
- The procedure involved excising the epiglottis, hyoepiglottic ligament, and pre-epiglottic space.
- Preservation of the false vocal cords and hyoid bone was a key aspect of the technique.
Main Results:
- All five patients achieved clear tumor margins.
- Three patients with up to 50% tongue base resection resumed oral diet and were decannulated.
- Two patients with more extensive (70%) tongue base resection required completion laryngectomy due to aspiration.
Conclusions:
- Partial supraglottic laryngectomy shows promise for treating limited tongue base lesions.
- Acceptable functional outcomes, including swallowing and breathing, can be achieved in select patients.
- Careful patient selection is crucial for successful outcomes with this organ-preserving approach.
