Summary
The Endoscopic-Assisted Transoral Approach (EATA) effectively removes benign parapharyngeal space tumors. This minimally invasive technique offers a safe and successful surgical option with minimal complications and short hospital stays.
Area of Science:
- Otolaryngology
- Head and Neck Surgery
- Minimally Invasive Surgery
Background:
- Endoscopic surgery enhances visualization in challenging anatomical regions.
- Innovative surgical approaches are crucial for improving surgical outcomes.
- The parapharyngeal space presents unique surgical access challenges.
Purpose of the Study:
- To evaluate the efficacy and safety of the Endoscopic-Assisted Transoral Approach (EATA) for resecting specific extracranial tumors.
- To demonstrate the application of EATA in treating parapharyngeal space (PPS) tumors.
- To analyze patient outcomes and complications associated with EATA.
Main Methods:
- Retrospective analysis of 11 patients undergoing EATA for extracranial tumor resection (2003-2025).
- Preoperative assessment included clinical examination, fiberoptic laryngoscopy, CT, and/or MRI.
- Surgical outcomes, histological diagnoses, complications, hospital stay, and follow-up were recorded.
Main Results:
- All 11 patients were successfully treated with EATA.
- Histological findings included various benign tumors: pleomorphic adenomas, schwannomas, ectopic thyroid, lipoma, and nasopharyngeal pleomorphic adenoma.
- No intraoperative or perioperative complications occurred; one case of Horner's syndrome was noted long-term.
- Mean hospital stay was 2.6 days, with a mean follow-up of 9.8 years.
Conclusions:
- EATA is a valid and safe surgical technique for benign, encapsulated, non-vascular PPS tumors.
- The approach is suitable for tumors displacing major vessels posteriorly.
- EATA may also benefit the management of similar tumors in the nasopharynx and masticator space.
