Summary
End-to-end hypoglossofacial anastomosis effectively restores facial nerve function after acoustic neuroma surgery. Significant improvements in facial reanimation are observed even beyond three years post-operation.
Area of Science:
- Neurosurgery
- Otolaryngology
- Facial Nerve Surgery
Background:
- Facial nerve (cranial nerve VII) transection is a known complication during acoustic neuroma removal.
- Hypoglossofacial anastomosis is a surgical technique to restore facial nerve function.
Purpose of the Study:
- To retrospectively evaluate the outcomes of end-to-end anastomosis between the facial nerve (VII) and hypoglossal nerve (XII).
- To assess facial reanimation results and complications following this procedure for acoustic neuroma excision.
Main Methods:
- Retrospective analysis of 33 patients undergoing end-to-end hypoglossofacial anastomosis after facial nerve transection during acoustic neuroma removal.
- Comparison of facial nerve function (House-Brackmann grading) between short-term (2-3 years) and long-term (>3 years) follow-up periods.
Main Results:
- Long-term follow-up showed significantly better facial nerve function recovery (86.4% Grade III) compared to short-term (46.2% Grade III).
- The most frequent complications were anastomosis disarticulation (57.6%) and tongue numbness (30.3%).
- No cases of dysphagia were reported.
Conclusions:
- End-to-end hypoglossofacial anastomosis is an effective surgical rehabilitation method for facial nerve function after acoustic neuroma surgery.
- Facial nerve function recovery can continue to improve more than three years post-surgery.

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...
01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
