Summary
Transcanal endoscopic resection effectively treats middle ear paragangliomas, showing improved hearing and quick recovery. This minimally invasive approach offers a safe and efficient treatment option for early-stage tumors.
Area of Science:
- Otolaryngology
- Neurosurgery
- Surgical Oncology
Background:
- Middle ear paragangliomas are rare tumors requiring effective surgical management.
- Transcanal endoscopic approaches offer potential advantages over traditional open surgeries.
Purpose of the Study:
- To evaluate the clinical and audiological outcomes of transcanal endoscopic resection for middle ear paragangliomas.
- To assess the safety and efficacy of this minimally invasive technique.
Main Methods:
- Retrospective multicenter study involving patients who underwent transcanal endoscopic surgery for middle ear paragangliomas between 2015 and 2020.
- Analysis of demographic data, audiological results, and postoperative follow-up including imaging.
Main Results:
- Twenty-three patients with stage 1 or 2 disease were included, with a mean follow-up of 2.7 years.
- Significant improvement in air-conduction thresholds (33.8 to 25.7 dB) and air-bone gaps (13.1 to 6.3 dB) were observed.
- Mean hospital stay was 27.7 hours, with no tumor regrowth detected on MRI.
Conclusions:
- Transcanal endoscopic resection is an effective and feasible treatment for early-stage middle ear paragangliomas.
- The procedure is associated with short operative times, minimal complications, and rapid patient discharge.
