Purpose
To describe the neurological results obtained in six patients with large Fisch C glomus jugulare tumors (GJT) in which a less aggressive, nerve-preserving surgical strategy was used to reduce surgical morbidity.
Methods
Prospective study of six patients with Fisch C GJT who underwent surgery in a tertiary care referral center from February 2015 to August 2017 with an average follow-up of 18 months. The intervention is the surgical technique used and the main outcome measures are recurrence and the functional preservation of the facial and lower cranial nerves.
Results
Gross total removal was obtained in the six patients with preservation of the medial wall of the jugular bulb protecting the lower cranial nerves. After follow-up, we obtained a House–Brackmann (H–B) grade II in three patients who were managed with an inferior facial nerve transposition. One patient managed with a facial bridge technique preserved a normal facial function and two patients who presented a H–B III before surgery went to H–B V after surgery and recovered to a H–B III after 4 months. Four patients were presented with dysphagia after surgery and required nasogastric tube placement. The average time for removal with return to normal oral feeding was 4.3 weeks. Three patients with preoperative Xth nerve dysfunction showed an adequate compensation of the opposite vocal fold in the postoperative period without dysphonia or aspiration.
Conclusion
The surgical techniques used in these patients provided good functional preservation without recurrence after an 8–30-month follow-up.
