✓ Hypoglossal-facial nerve anastomosis is one of the procedures frequently performed to restore function after facial palsy secondary to surgery for removal of cerebellopontine angle tumors. The published results of hypoglossal-facial nerve anastomosis have been variable, and there are still questions about the indications, timing, and surgical techniques for this procedure. The goals of the present retrospective analysis of 22 cases of hypoglossal-facial nerve anastomosis were to assess the extent of the functional recovery and to analyze the factors affecting this recovery. The 22 cases of complete facial palsy were gleaned from a series of 245 cases of cerebellopontine angle tumors treated surgically by one of the authors. Twenty patients had an acoustic neuroma (average size 3.5 cm), one patient had a petrous meningioma, and one patient had a facial neuroma. The average age of the patients was 47.3 years (range 19 to 69 years). The average interval from tumor surgery to hypoglossal-facial nerve anastomosis was 6.4 months (range 12 days to 17 months), and the average follow-up period after the procedure was 65 months. The results were graded as good, fair, poor, or failure according to a new method of classifying facial nerve function after hypoglossal-facial nerve anastomosis. The results were good in 14 cases (63.6%), fair in three (13.6%), and poor in four (18.2%); one (4.5%) was a failure. Good and fair results occurred with higher frequency in younger patients who were operated on within shorter intervals, although these relationships were not statistically significant. There were no surgical complications. Good or fair results were achieved in 17 (77.3%) of the 22 cases, and thus hypoglossal-facial nerve anastomosis is considered an effective procedure for most patients with facial palsy after surgery for cerebellopontine angle tumors.

Nerve Anastomosis

The facial nerve is main motor nerve of the face and its injury leads to total ipsilateral paralysis. There are several surgical procedures in reconstruction of the facial nerve, and the most frequent one is hypoglosso-facial anastomosis. In this study were analysed a series of 69 patients operated on Institute of neurosurgery from 1981 to 2000 year. The most frequent cause of injury was the operation of cerebellopontine angle tumors, as well as the skull base fractures. Hypoglosso-facial anastomosis was done in 57 patients, in 5 cases we performed nerve grafting in the cerebellopontine angle, and in 7 patients the facial nerve was operated peripherally. Results were analyzed in 27 of 57 patients with hipoglosso-facial nerve anastomosis. Functional recovery was achived in 22 (81,4%) patients.

AbstractObjective:To report a case of meningioma arising from the nervus intermedius.Methods:This paper comprises a case report, literature review, and discussion regarding the presentation of a nervus intermedius meningioma, comparing and contrasting this to other relevant neoplasms of the internal auditory canal and cerebellopontine angle.Results:Tumours of the cerebellopontine angle include vestibular schwannomas, facial schwannomas and, more rarely, nervus intermedius schwannomas. The nervus intermedius is a division of the facial nerve at the cerebellopontine angle, with parasympathetic and afferent somatic components. Our patient presented with progressive hearing loss. An ipsilateral internal auditory canal mass at the fundus, as indicated by magnetic resonance imaging and electroneuronography, was suggestive of vestibular schwannoma. Intra-operative dissection revealed a nervus intermedius tumour. Histological evaluation indicated a meningioma rather than a schwannoma.Conclusion:This is the first reported case of meningioma involving the nervus intermedius. The implications this pathology may have on surgical approach, facial nerve outcomes, and the need for improved pre-operative imaging and intra-operative monitoring are discussed. A review of the current literature on nervus intermedius tumour is provided.

AIM: This study aims to evaluate the outcome of patients with complete facial paralysis following surgery to cerebellopontine angle tumours or following traumatic petrous bone fractures after reanimation by hypoglossal-facial anastomosis as regards clinical improvement of facial asymmetry and facial muscle contractility as well as complications associated with hypoglossal-facial reanimation procedure. METHODS: This thesis included a prospective study to be carried out on 15 patients with unilateral complete lower motor neuron facial paralysis (11 patients after cerebellopontine angle tumour resection and 4 patients after traumatic transverse petrous bone fracture) operated upon by end to end hypoglossal-facial nerve anastomosis in Cairo university hospitals in the period between June 2015 and January 2017. RESULTS: At one year follow up the improvement of facial nerve functions were as follows: Three cases (20%) had improved to House Hrackmann grade II, eleven cases (73.33%) had improved to grade III, and one patient (6.66%) had improved to House Brackmann grade IV. CONCLUSION: Despite the various techniques in facial reanimation following facial nerve paralysis, the end to end hypoglossal-facial nerve anastomosis remains the gold standard procedure with satisfying results in cases of the viable distal facial stump and non-atrophic muscles. Early hypoglossal-facial anastomotic repair after acute facial nerve injury is associated with better long-term facial function outcomes and should be considered in the management algorithm.

Cerebellopontine Angle Tumors

Introduction: Cerebellopontine angle tumors are a surgical challenge to many neurosurgeons who want to operate in this space. Although most of these tumors are benign, they are a challenge because of the complex anatomy and important neurovascular structures that traverse this space. Most common cerebellopontine angle tumor is vestibular schwannoma. The management of these cases is essentially surgical. There has been a change in the surgical strategy over the years from simple intratumoral decompression to complete microsurgical excision, to radical excision with facial nerve and hearing preservation.Objectives: To study the clinical and radiological characteristics, know the pathological types and determine the surgical resectability and outcome of cerebellopontine angle tumor.Materials and Methods: It is a retrospective study done in the department of Neurosurgery, Apollo Hospitals Dhaka. 34 patients diagnosed with cerebellopontine angle tumor were recruited into the study.Results: Among 34 cases of cerebellopontine angle tumors vestibular schwannoma alone constituted 79%. Most of the tumors were large or giant tumors. Total resection was done in 25% of vestibular schwannoma and 50% of meningiomas. Anatomical preservation of facial nerve was achieved in 73% of patients. Facial nerve function as measured by the House Brackmann system. Postoperatively 61% had a score of 1 or 2; 29% had a score of 3 or 4; and 8% had a score of 5 or 6. Other complications included 2 cases of CSF leak, 3 cases of meningitis, 2 cases of lower cranial nerve palsy and 1 patient died.Conclusion: Cerebellopontine angle tumors show high incidence from 3rd to 5th decade with common symptoms being hearing loss and ataxia. Most of the patients presented at a delayed stage with large to giant tumors with no useful hearing. Sub total excision with keeping anterior part of tumor for preserving facial nerve function is the goal.Pulse Vol.8 January-December 2015 p.8-14
