Abstract
Background: Hypoglossal-facial nerve (12-7) anastomosis can restore symmetry and voluntary movement on the face in patients with facial nerve paralysis. Traditional 12-7 transfer includes direct end-to-end nerve anastomosis, sacrificing the entire hypoglossal nerve. Contemporary, end-to-side anastomosis, or split anastomosis techniques limit tongue morbidity by preserving some hypoglossal nerve. Direct outcome comparisons between these techniques are limited. Objective: To compare reported outcomes of facial movement, tongue, speech, and swallow outcomes among the different types of hypoglossal-facial nerve anastomosis schemes. Evidence Review: For this systematic review and meta-analysis, a comprehensive strategy was designed to search PubMed, Scopus, and the Cochrane Database from inception to January 2021, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis, reporting guideline yielding 383 results. Any participant who underwent 12-7 transfer using any of the three techniques, with or without an interposition graft, and had documented preoperative and postoperative evaluation of facial nerve function with a validated instrument such as House-Brackmann (HB), was considered for inclusion. Secondary outcomes of synkinesis, tongue atrophy, and speech or swallowing dysfunction were also compared. Forty-nine studies met inclusion criteria, representing data from 961 total patients who underwent 12-7 transfer. Results: The proportion of good HB outcomes (HB I-III) did not differ by anastomosis type: End-to-side and end-to-end anastomosis (73% vs. 59%, p = 0.07), split and end-to-end anastomosis (62% vs. 59%, p = 0.88), and end-to-side anastomosis and split anastomosis (73% vs. 62%, p = 0.46). There was no difference in reported synkinesis rates between the anastomosis types. However, end-to-side anastomosis (z = 6.55, p < 0.01) and split anastomosis (z = 3.58, p < 0.01) developed less tongue atrophy than end-to-end anastomosis. End-to-side anastomosis had less speech/swallowing dysfunction than end-to-end anastomosis (z = 3.21, p < 0.01). Conclusion: End-to-side and split anastomoses result in similar HB facial nerve outcomes as the traditional end-to-end 12-7 anastomosis. End-to-side anastomosis has decreased complications of tongue atrophy and speech/swallow dysfunction compared to end-to-end anastomosis. In addition, split anastomosis has decreased rates of tongue atrophy compared to end-to-end anastomosis.

Abstract
BACKGROUND AND OBJECTIVE Intraoperative neurophysiological monitoring allows us to predict the functional status of the facial nerve after vestibular schwannoma surgery. Due to the great variability of the neurophysiological protocols used for it, the goal of this study is to determine the prognostic ability of our neurophysiological protocol. MATERIAL AND METHODS We have performed a statistical analysis of the neurophysiological monitoring data collected from patients operated between March 2009 and July 2021 at the Neurosurgery Service of Salamanca according to their functional status, both in the immediate post-surgical period and one year after surgery. RESULTS A number of 51 patients between 46 and 63 years old (median: 54) were analyzed. We have found significant differences studying the threshold value of the stimulation intensity of the facial nerve and the variation of the Cortico-bulbar Evoked Motor Potentials (P=0.043 and P=0.011, respectively) between the patients with good and bad clinical situation after surgery. The most discriminating intensity threshold value was 0.35mA (Sensitivity: 85%; Specificity: 48%). No statistical relationship was found in the study group one year after surgery. CONCLUSIONS Our intraoperative monitoring protocol allows us to predict the clinical situation of patients in the immediate postoperative period and improve information for the patient and her relatives after surgery. We cannot, however, use these parameters to predict the functional situation one year after surgery and make clinical decisions in this regard.

Abstract
Facial nerve palsy directly impacts the quality of life, with patients with facial nerve palsy showing increased rates of depression and limitations in social activities. Although facial nerve palsy is not life-threatening, it can devastate the emotional and social lives of affected individuals. Hence, improving the prognosis of patients with this condition is of vital importance. The prognosis of patients with facial nerve palsy is determined by the cause of the disease, the degree of damage, and the treatment provided. The facial nerve can be easily damaged by middle ear and temporal bone surgery, trauma or infection, and tumors of the peripheral facial nerve or tumors surrounding the nerve secondary to systemic disease. In addition, idiopathic, acquired immunodeficiency syndrome and autoimmune diseases may damage the facial nerve. The treatment used for facial paralysis depends on the cause. Treatment of facial nerve amputation injury varies depending on the degree of facial nerve damage, comorbidities, and duration of injury. Recently, interest has increased in Toll-like receptors (TLRs) related to innate immune responses, as these receptors are known to be related to nerve regeneration. In addition to innate immune cells, both neurons and glia of the central nervous system (CNS) and peripheral nervous system (PNS) express TLRs. A comprehensive literature review was conducted to assess the expression and role of TLRs in peripheral nerve injury and subsequent regeneration. Studies conducted on rats and mice have demonstrated the expression of TLR1-13. Among these, TLR2-5 and TLR7 have received the most research attention in relation to facial nerve degeneration and regeneration. TLR10, TLR11, and TLR13 increase during compression injury of the facial nerve, whereas during cutting injury, TLR1-5, TLR8, and TLR10-13 increase, indicating that these TLRs are involved in the degeneration and regeneration of the facial nerve following each type of injury. Inadequate TLR expression or absence of TLR responses can hinder regeneration after facial nerve damage. Animal studies suggest that TLRs play an important role in facial nerve degeneration and regeneration.

Abstract
OBJECTIVE To investigate microanatomic organizations of the extratemporal facial nerve and its branches, hypoglossal nerve, sural nerve, and great auricular nerve. METHODS Nerve samples were dissected in 12 postmortem autopsies, and histomorphometric analyses were conducted. RESULTS There was no significant difference between the right and left sides of the nerve samples for the nerve area, fascicle area, number of fascicles and average number of axons. The lowest mean fascicle number was found in the hypoglossal nerve (4.9 ± 1.4) while the highest was in great auricular nerve (11.4 ± 6.8). The highest nerve area (3,182,788 ± 838,430 μm2), fascicle area (1,573,181 ± 457,331 μm2) and axon number (14,772 ± 4402) were in hypoglossal nerve (p < 0.05). The number of axons per unit nerve area was higher in the facial nerve, truncus temporofacialis, truncus cervicofacialis and hypoglossal nerve, which are motor nerves, compared to the sural nerve and great auricular nerve, which are sensory nerves (p < 0.05). The number of axons per unit fascicle area was also higher in motor nerves than in sensory nerves (p < 0.05). CONCLUSION In the present study, it was observed that each nerve contained a different number of fascicles and these fascicles were different both in size and in the number of axons they contained. All these variables could be the reason why the desired outcomes cannot always be achieved in nerve reconstruction.

Abstract
The aim of this article is to provide an overview on paediatric facial paralysis, looking into aetiology, epidemiology, assessment and investigation and subsequent treatment options available. Facial paralysis describes the inability to activate the muscles of fascial expression. Overall, it affects 2.7 per 100 000 children under 10 years old and 10.1 per 100 000 children over 10 years old each year. There are many causes of facial paralysis and the outcomes and necessary treatments vary depending on the cause. The mainstays of medical management are corticosteroids and facial therapy; however, when the facial palsy persists, facial deformity surgery is an option to improve the facial symmetry, protect vision and recreate dynamic movement.

Abstract
The great auricular nerve (GAN) is a superficial branch of the cervical plexus that innervates parts of the mandible, auricle, and earlobe. Over the past 30 years, the GAN has become the nerve graft donor of choice for many surgeons for reconstructing injured facial nerves. In this review, we discuss the anatomy and function of the GAN, while focusing on surgical landmarks and the characteristics that make it a suitable nerve graft donor. In addition, we present and summarize published case reports on use of the GAN for grafting. We hope that this review will provide surgeons with an up-to-date and concise reference.

Using the Post-Descendens Hypoglossal Nerve in Hypoglossal-Facial Anastomosis: An Anatomic and Histologic Feasibility Study. Oper Neurosurg (Hagerstown) 2020; 19:436-443.

Abstract
BACKGROUND Hypoglossal-facial anastomosis (HFA) is a popular facial reanimation technique. Mobilizing the intratemporal segment of the facial nerve and using the post-descendens hypoglossal nerve (ie, the segment distal to the take-off of descendens hypoglossi) have been proposed to improve results. However, no anatomic study has verified the feasibility of this technique. OBJECTIVE To assess the anatomic feasibility of HFA and the structural compatibility between the 2 nerves when the intratemporal facial and post-descendens hypoglossal nerves are used. METHODS The facial and hypoglossal nerves were exposed bilaterally in 10 sides of 5 cadaveric heads. The feasibility of a side-to-end (ie, partial end-to-end) HFA with partial sectioning of the post-descendens hypoglossal nerve and the mobilized intratemporal facial nerve was assessed. The axonal count and cross-sectional area of the facial and hypoglossal nerves at the point of anastomosis were assessed. RESULTS The HFA was feasible in all specimens with a mean (standard deviation) 9.3 (5.5) mm of extra length on the facial nerve. The axonal counts and cross-sectional areas of the hypoglossal and facial nerves matched well. Considering the reduction in the facial nerve cross-sectional area after paralysis, the post-descendens hypoglossal nerve can provide adequate axonal count and area to accommodate the facial nerve stump. CONCLUSION Using the post-descendens hypoglossal nerve for side-to-end anastomosis with the mobilized intratemporal facial nerve is anatomically feasible and provides adequate axonal count for facial reanimation. When compared with use of the pre-descendens hypoglossal nerve, this technique preserves C1 fibers and has a potential to reduce glottic complications.

Abstract
BACKGROUND During surgical treatment of lesions involving the skull base, conductive hearing is often sacrificed due to tympanum destruction. This study aimed to develop a method for tympanum reconstruction using a sternocleidomastoid (SCM) flap to preserve conductive hearing during lateral skull base surgery. METHODS This study included five patients with lateral skull base lesions who underwent surgery including tympanum reconstruction with an SCM flap between July 2015 and November 2017. RESULTS Three patients seen with facial nerve schwannoma, and two had paraganglioma of the head and neck. All patients' inferior and posterior tympanic walls were resected; the tympanum and ossicular chain were reconstructed with an SCM flap and prosthesis. The mean postoperative air-bone gap was 14 dB. No lesion recurrences were observed until the last follow-up. CONCLUSION The SCM flap is effective in preserving conductive hearing through reconstruction of the inferior and posterior tympanic walls in lateral skull base surgery.

Abstract
OBJECTIVE To evaluate VIIth-XIIth cranial nerve (hypoglossal-facial nerve) anastomosis results by age. METHOD A total of 34 patients who attended a follow-up visit in 2016, aged 20-63 years, were enrolled. The House-Brackmann facial nerve function grading system and the Facial Clinimetric Evaluation scale were applied. RESULTS Regarding post-anastomosis facial nerve function, in the group aged 40 years or less, 14 patients (78 per cent) had House-Brackmann grade III and 4 patients (22 per cent) had House-Brackmann grade IV facial nerve function post-anastomosis. In the group aged over 40 years, nine patients (56 per cent) had House-Brackmann grade III and seven patients (44 per cent) had House-Brackmann grade IV facial nerve function post-anastomosis. There was a statistically significant difference between the two groups in mean facial movement domain scores (p = 0.02). Analysis between age and facial movement score in all 34 patients demonstrated a moderate negative correlation (Pearson correlation coefficient: -0.38) and statistical significance (p = 0.02). CONCLUSION Facial reanimation yielded better results in younger than in older patients.

Abstract
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.

Neurorrhaphy for Facial Reanimation with Interpositional Graft: Outcome in 23 Patients and the Impact of Timing on the Outcome. World Neurosurg 2019; 126:e688-e693. [PMID: 30844532 DOI: 10.1016/j.wneu.2019.02.124] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2019] [Revised: 02/11/2019] [Accepted: 02/12/2019] [Indexed: 10/27/2022]
Abstract
OBJECTIVE Neurorrhaphy with interpositional graft is a practical technique to achieve facial reanimation when the continuity of the facial nerve is interrupted and a large gap between the proximal and distal stump exists. The aim of this study was to report long-term outcomes of neurorrhaphy for facial reanimation with interpositional graft. The roles of some variable factors in the outcome of neurorrhaphy with interpositional graft were also evaluated and compared. METHODS A retrospective case series from a single tertiary referral center comprised 23 patients with facial nerve interruptions who underwent neurorrhaphy with interpositional graft using either end-to-end anastomosis or end-to-side hypoglossal-facial technique. Preoperative data (age, sex, primary lesion, interval from paralysis to surgery, facial nerve function), intraoperative data (surgical approach, graft and type of neurorrhaphy), and postoperative data (facial nerve function) were collected and analyzed. RESULTS Mean follow-up time was 26.6 ± 11.9 months. Patients who underwent neurorrhaphy for facial reanimation within 1 year after onset of facial paralysis were more likely to achieve House-Brackmann grade ≤3 compared with patients who underwent neurorrhaphy >1 year after onset of facial paralysis (odds ratio = 23.85, P = 0.04). No other factors were associated with improved outcomes. CONCLUSIONS Early neurorrhaphy with interpositional graft (≤1 year) for facial reanimation resulted in better final facial nerve function outcomes compared with a delayed procedure.

Abstract
Objectives: A meta-analysis was conducted on the outcome of facial nerve function after hypoglossal-facial nerve anastomosis in humans. The roles of the timing of and the underlying cause for surgery, the type of the repair, and previous facial nerve function in the final result were analyzed. Methods: Articles were identified by means of a PubMed search using the key words “facial-hypoglossal anastomosis,” which yielded 109 articles. The data were pooled from existing literature written in English or French. Twenty-three articles were included in the study after we excluded those that were technical reports, those describing anastomosis to cranial nerves other than the hypoglossal, and those that were experimental animal studies. Articles that reported facial nerve function after surgery and timing of repair were included. Facial nerve function had to be reported according to the House-Brackmann scale. If there was more than 1 article by the same author(s), only the most recent article and those that did not overlap and that matched the above criteria were accepted. The main parameter of interest was the rate of functional recovery of the facial nerve after anastomosis. This parameter was compared among all groups with Pearson's X2 test in the SPSS program for Windows. Statistical significance was set at a p level of less than .05. Results: Analysis of the reports indicates that early repair, before 12 months, provides a better outcome. The severity of facial nerve paralysis does not have a negative effect on prognosis. Gunshot wounds and facial neuroma are the worst conditions for favorable facial nerve recovery after anastomosis. Transection of the hypoglossal nerve inevitably results in ipsilateral tongue paralysis and atrophy. Modification of the anastomosis technique seems to resolve this problem. Nevertheless, the effect of modified techniques on facial reanimation is still unclear, because the facial nerve function results were lacking in these reports. Conclusions: Hypoglossal-facial nerve anastomosis is an effective and reliable technique that gives consistent and satisfying results.

Abstract
BACKGROUND The hypoglossal (with or without grafts) and masseter nerves are frequently used as axon donors for facial reinnervation when no proximal stump of the facial nerve is available. We report our experience treating facial nerve palsies via hemihypoglossal-to-facial nerve transfers either with (HFG) or without grafts (HFD), comparing these outcomes against those of masseteric-to-facial nerve transfers (MF). METHOD A total of 77 patients were analyzed retrospectively, including 51 HFD, 11 HFG, and 15 MF nerve transfer patients. Both the House-Brackmann (HB) scale and our own, newly-designed scale to rate facial reanimation post nerve transfer (quantifying symmetry at rest and when smiling, eye occlusion, and eye and mouth synkinesis when speaking) were used to enumerate the extent of recovery. RESULTS With both the HB and our own facial reanimation scale, the HFD and MF procedures yielded better outcome scores than HFG, though only the HGD was statistically superior. HGD produced slightly better scores than MF for everything but eye synkinesis, but these differences were generally not statistically significant. Delaying surgery beyond 2 years since injury was associated with appreciably worse outcomes when measured with our own but not the HB scale. The only predictors of outcome were the surgical technique employed and the duration of time between the initial injury and surgery. CONCLUSIONS HFD appears to produce the most satisfactory facial reanimation results, with MF providing lesser but still satisfactory outcomes. Using interposed grafts while performing hemihypoglossal-to-facial nerve transfers should likely be avoided, whenever possible.

Abstract
BACKGROUND The hypoglossal facial anastomosis (HFA) is the gold standard for facial reanimation in patients with severe facial nerve palsy. The major drawbacks of the classic HFA technique are lingual morbidities due to hypoglossal nerve transection. The side-to-end HFA is a modification of the classic technique with fewer tongue-related morbidities. OBJECTIVES In this study we compared the outcome of the classic end-to-end and the direct side-to-end HFA surgeries performed at our center in regards to the facial reanimation success rate and tongue-related morbidities. METHODS Twenty-six successive cases of HFA were enrolled. In 9 of them end-to-end anastomoses were performed, and 17 had direct side-to-end anastomoses. The House-Brackmann (HB) and Pitty and Tator (PT) scales were used to document surgical outcome. The hemiglossal atrophy, swallowing, and hypoglossal nerve function were assessed at follow-up. RESULTS The original pathology was vestibular schwannoma in 15, meningioma in 4, brain stem glioma in 4, and other pathologies in 3. The mean interval between facial palsy and HFA was 18 months (range: 0-60). The median follow-up period was 20 months. The PT grade at follow-up was worse in patients with a longer interval from facial palsy and HFA (P value: 0.041). The lesion type was the only other factor that affected PT grade (the best results in vestibular schwannoma and the worst in the other pathologies group, P value: 0.038). The recovery period for facial tonicity was longer in patients with radiation therapy before HFA (13.5 vs. 8.5 months) and those with a longer than 2-year interval from facial palsy to HFA (13.5 vs. 8.5 months). Although no significant difference between the side-to-end and the end-to-end groups was seen in terms of facial nerve functional recovery, patients from the side-to-end group had a significantly lower rate of lingual morbidities (tongue hemiatrophy: 100% vs. 5.8%, swallowing difficulty: 55% vs. 11.7%, speech disorder 33% vs. 0%). CONCLUSION With the side-to-end HFA technique the functional restoration outcome is at least as good as that following the classic end-to-end HFA, but the complications related to the complete hypoglossal nerve transection can be avoided. Best results are achieved if this procedure is performed within the first 2 years after facial nerve injury. Patients with facial palsy of longer duration also have the chance for good functional restoration after HFA.

Abstract
The management of facial paralysis continues to evolve. Understanding the facial nerve anatomy and the different methods of evaluating the degree of facial nerve injury are crucial for successful management. When the facial nerve is transected, direct coaptation leads to the best outcome, followed by interpositional nerve grafting. In cases where motor end plates are still intact but a primary repair or graft is not feasible, a nerve transfer should be employed. When complete muscle atrophy has occurred, regional muscle transfer or free flap reconstruction is an option. When dynamic reanimation cannot be undertaken, static procedures offer some benefit. Adjunctive tools such as botulinum toxin injection and biofeedback can be helpful. Several new treatment modalities lie on the horizon which hold potential to alter the current treatment algorithm.

Abstract
Facial palsy is a relatively common condition, from which most cases recover spontaneously. However, each year, there are 127,000 new cases of irreversible facial paralysis. This condition causes aesthetic, functional and psychologically devastating effects in the patients who suffer it. Various reconstructive techniques have been described, but there is no consensus regarding their indication. While these techniques provide results that are not perfect, many of them give a very good aesthetic and functional result, promoting the psychological, social and labour reintegration of these patients. The aim of this article is to describe the indications for which each technique is used, their results and the ideal time when each one should be applied.

Abstract
BACKGROUND The aim of this study was to analyze complications of vestibular schwannoma (VS) microsurgery. MATERIAL AND METHODS A retrospective study was performed in 333 patients with unilateral vestibular schwannoma indicated for surgical treatment between January 1997 and December 2012. Postoperative complications were assessed immediately after VS surgery as well as during outpatient followup. RESULTS In all 333 patients microsurgical vestibular schwannoma (Koos grade 1: 12, grade 2: 34, grade 3: 62, and grade 4: 225) removal was performed. The main neurological complication was facial nerve dysfunction. The intermediate and poor function (HB III-VI) was observed in 124 cases (45%) immediately after surgery and in 104 cases (33%) on the last followup. We encountered disordered vestibular compensation in 13%, permanent trigeminal nerve dysfunction in 1%, and transient lower cranial nerves (IX-XI) deficit in 6%. Nonneurological complications included CSF leakage in 63% (lateral/medial variant: 99/1%), headache in 9%, and intracerebral hemorrhage in 5%. We did not encounter any case of meningitis. CONCLUSIONS Our study demonstrates that despite the benefits of advanced high-tech equipment, refined microsurgical instruments, and highly developed neuroimaging technologies, there are still various and significant complications associated with vestibular schwannomas microsurgery.

Abstract
Objectives: This retrospective case review was performed to determine the facial function outcome of an end-to-side interposed donor grafting technique in patients who had a nonresponsive and partially injured facial nerve during a translabyrinthine approach for vestibular schwannoma resection. Methods: The study included patients with silent electrophysiological tests after partial injury of the facial nerve during translabyrinthine schwannoma resection surgery in a tertiary referral hospital. The patients underwent end-to-side interposed donor grafting as a facial nerve reinforcement technique, and we evaluated their facial function after 1 year of follow-up. Results: Four cases with intact preoperative facial function were included (3 men and 1 woman). All patients had a lack of electrical response from the facial nerve and partial anatomic injury after a translabyrinthine approach. An end-to-side interposed donor grafting technique was performed. The donor grafts used were the sural nerve (2 patients), superior vestibular nerve (1 patient), and greater auricular nerve (1 patient). All patients achieved a good House-Brackmann grade. Ocular adjuvant procedures were performed in all patients. Conclusions: Immediate repair of the facial nerve with an interposed donor graft may provide better facial function in patients who have no electrical response from a partially injured facial nerve after vestibular schwannoma surgery.

Abstract
Chondrosarcomas of the skull base are locally aggressive tumours, and radical surgical resection is often difficult because of involvement of important neural structures in the skull base. We report the successful total resection of a huge skull base chondrosarcoma extending both intra- and extracranially. The tumour involved the left mastoid process, entire petrous bone, jugular foramen, posterior fossa and the parapharyngeal space. Since the facial nerve in the fallopian canal was totally involved by the tumour, the nerve was sacrificed and reconstructed using a great auricular nerve graft. The removal of the tumour was radical and complete. The functional recovery of the reconstructed facial nerve was excellent. The patient has almost fully recovered from the other neurological symptoms and has been free of tumour recurrence for 4 years after surgery.

Abstract
To evaluate the results of facial nerve reanimation after facial nerve injury by means of hypoglossal to facial nerve anastomosis. Retrospective case review. Private neuro-otologic and cranial base quaternary referral center. Sixty patients underwent hypoglossal to facial nerve anastomosis for facial nerve reanimation between April 1987 and December 2010. Only forty patients completed a minimal follow up of 24 months at the time of evaluation and were included in the study population. Facial nerve paralysis was present for a mean duration of 11.3 months (range 2-42 months) and all the patients had a HB grade VI prior their surgery. Final facial nerve motor function. The most common cause of facial paralysis was vestibular Schwannoma surgery. All the patients achieved a postoperative HB grade III or IV after a mean follow-up time of 20 months. The facial movements were detected after a period that ranged from ranged from 5 to 9 months. Only 4 patients suffered from difficulties during eating and drinking and three of them had associated lower cranial nerve deficit. Despite the various techniques in facial reanimation following total facial nerve paralysis, the end to end of hypoglossal to facial nerve anastomosis remains one of the best treatments in cases of viable distal facial stump and nonatrophic musculature.

Once a successful approach was derived, this was used on 19 live rats under anesthesia. Fourteen rats had a 1-minute facial nerve crush performed, and 5 had a sham surgery with complete surgical exposure of the facial nerve but no crush. Rats were followed for a 12-week duration evaluating immediate postoperative facial nerve function, complications, and survival. RESULTS All 14 (100%) rats that underwent surgery with crush injury had complete facial paralysis postoperatively. Complete facial paralysis was defined as loss of eye-blink reflex, flat vibrissae, and lack of vibrissae movement. The 5 sham surgery rats had complete facial function postoperatively. Surgery was performed by 2 separate surgeons with no difference in outcome between the 2. Complications occurred in only 1 animal (1/19, 5.3%), which was a corneal abrasion requiring sacrifice. CONCLUSION Our group describes a consistent method for performing an intracranial crush injury in the rat. This new model and its applications in translational facial nerve research are promising, particularly with tumors or lesions at the cerebellopontine angle.

Abstract
BACKGROUND An understanding of the management of chronic facial palsy is vital for otolaryngologists, due to its common presentation to ENT surgeons. There is currently a lack of consensus on the optimum management of this condition. This article reviews the existing literature and offers a perspective on current management, as well as an insight into future treatments. METHODS A literature search was performed, using the Medline, Embase and Cochrane databases from 1966 to the present, using the keywords listed below. Articles were reviewed. Selection was limited to English language articles on human subjects. RESULTS AND CONCLUSION A tailored, multidisciplinary approach using combinatorial therapy should be used for reanimation of the face following facial palsy. Advances in surgical and non-surgical techniques, and the exchange of information from centres of excellence via global databases, will enable objective appraisal of results and the development of an evidence-based approach to facial reanimation.

Abstract
AbstractObjective:This study aimed to evaluate retrospectively the results of experience with end-to-end anastomosis of cranial nerves VII and XII, performed due to transection of the facial nerve during acoustic neuroma removal.Methods:We assessed the facial reanimation results of 33 patients whose facial nerves had been transected during acoustic neuroma excision via a retrosigmoid approach, between 1985 and 2006, and who underwent end-to-end hypoglossofacial anastomosis. We compared the facial nerve functions of patients receiving short term (two to three years) and long term (more than three years) follow up, and we assessed any complications of the anastomosis.Results:A House–Brackmann grade III facial function was achieved in 46.2 and 86.4 per cent of the patients in the short and long term, respectively. House–Brackmann grade IV facial function was achieved in 53.8 and 13.6 per cent of the patients in the short and long term, respectively. There was a statistically significant difference between the facial recovery results, comparing the short and long term follow-up periods (p = 0.03). Disarticulation was the most common complication, seen in 19 (57.6 per cent) patients; numbness of the tongue was the next commonest (10 (30.3 per cent) patients). None of the patients developed dysphagia.Conclusion:Despite such morbidities as disarticulation and tongue numbness, end-to-end hypoglossofacial anastomosis is still an effective procedure for the surgical rehabilitation of static and dynamic facial nerve functions. Significant improvement in facial nerve function can occur more than three years post-operatively.

Abstract
Facial paralysis triggers aesthetic and functional changes that hold significant physical and psychological repercussions to those suffering from this condition. Botulinum toxin may be used to reduce the facial asymmetry encountered in patients suffering from facial paralysis. The onset of improvement starts usually 15 days after the injection. Patients' satisfaction increases with time, especially after 30 days. Adverse events concerning the perioral area are found but resume as the patients get used to the new dynamics. The use of botulinum toxin is effective in decreasing the hyperkinesis contralateral to facial paralysis. The global aesthetic aspect of the face improves.

Abstract
OBJECT The aim of this study was to address the efficiency and safety of direct end-to-side facial-hypoglossal nerve anastomosis for facial palsy rehabilitation. METHODS The authors conducted a retrospective study of 12 consecutive procedures performed between December 2000 and February 2006. Facial palsies were caused by the surgical removal of tumors in the brainstem, cerebellopontine angle, or mastoid process. Direct end-to-side facial-hypoglossal anastomosis was performed in each case. Facial function (evaluated using the overall percentage of facial function and House-Brackmann scale grades), as well as tongue trophicity and mobility, were assessed at 6, 12, and 24 months after surgery. Postoperative early and late complications were systematically reviewed. RESULTS The mean delay between tumoral and reparative surgery was 15.9 +/- 4 months (median 11 months). Preoperatively, the mean percentage facial function score was 11.6 +/- 1.7% (45% of patients with House-Brackmann Grade 5 facial palsy and 55% of patients with House-Brackmann Grade 6). Mean facial function scores increased to 19.3, 32.2, and 43.8% at 6, 12, and 24 months after surgery, respectively. Twenty-four months after surgery, 50% of cases had House-Brackmann Grade 3 facial palsy and 50% had Grade 4. A significantly better recovery at 24 months was observed postoperatively for neural lesions occurring in the mastoid or the brainstem compared with those in the cerebellopontine angle. Tongue hemiparesis was observed in 5 patients (41.7%), 2 of whom had tongue hypotrophy (16.7%). No patient complained of swallowing or speech disturbance. Facial synkinesis was noted in 1 patient (8.3%). CONCLUSIONS Facial recovery after direct end-to-side facial-hypoglossal nerve anastomosis is similar to results observed with end-to-end or end-to-side facial-hypoglossal nerve anastomosis with an interpositional graft. Tongue hypotrophy and palsy were observed in a small number of cases. This procedure allows one to minimize, although not fully prevent, facial synkinesis. The site of the neural lesion appears to be an important factor in the prognosis of recovery.

Abstract
OBJECTIVE Hypoglossal-facial neurorrhaphy has been widely used for reanimation of paralyzed facial muscles after irreversible proximal injury of the facial nerve. However, complete section of the hypoglossal nerve occasionally results in hemiglossal dysfunction and interferes with swallowing and speech. To reduce this morbidity, a modified technique with partial section of the hypoglossal nerve after mastoid dissection of the facial nerve (HFM) has been used. We report our experience with the HFM technique, retrospectively comparing the outcome with results of the classic hypoglossal-facial neurorrhaphy. METHODS A retrospective review was performed in 36 patients who underwent hypoglossal-facial neurorrhaphy with the classic (n = 12) or variant technique (n = 24) between 2000 and 2006. Facial outcome was evaluated with the House-Brackmann grading system, and tongue function was evaluated with a new scale proposed to quantify postoperative tongue alteration. The results were compared, and age and time between nerve injury and surgery were correlated with the outcome. RESULTS There was no significant difference between the two techniques concerning facial reanimation. A worse outcome of tongue function, however, was associated with the classic technique (Mann-Whitney U test; P < 0.05). When HFM was used, significant correlations defined by the Spearman test were identified between preoperative delay (rho = 0.59; P = 0.002) or age (rho = 0.42; P = 0.031) and results of facial reanimation evaluated with the House-Brackmann grading system. CONCLUSION HFM is as effective as classic hypoglossal-facial neurorrhaphy for facial reanimation, and it has a much lower morbidity related to tongue function. Better results are obtained in younger patients and with a shorter interval between facial nerve injury and surgery.

Abstract
BACKGROUND The therapeutic uses of botulinum toxin have been expanding due to deeper knowledge of its molecular behaviour and different mechanisms of action. OBJECTIVE To present suggested doses of Botox and Dysport for controlling the muscle hyperkinetic activity in facial palsy in the perioral area and to review other uses. METHODS An extensive updated literature review on the success and limits of the botulinum neurotoxin (BoNT) therapeutic treatments. RESULTS/CONCLUSION BoNT can be considered to be the preferred single method for many disorders; it has substituted for some conventional surgical methods and it can be associated with other therapies to increase overall treatment performance. Depending on the disorder, the lack of permanent effect causes no major inconvenience.

Abstract
OBJECTIVE The goal of this study was to determine the various anatomical and surgical relationships between the facial and hypoglossal nerves to define the required length of each for a nerve transfer, either by means of a classical hypoglossal-facial nerve anastomosis or combined with any of its variants developed to reduce tongue morbidities. METHODS Five adult cadaver heads were bilaterally dissected in the parotid and submaxillary regions. Two clinical cases are described for illustration. RESULTS The prebifurcation extracranial facial nerve is found 4.82 +/- 0.88 mm from the external auditory meatus, 5.31 +/- 1.50 mm from the mastoid tip, 15.65 +/- 0.85 mm from the lateral end of C1, 17.19 +/- 1.64 mm from the border of the mandible condyle, and 4.86 +/- 1.29 mm from the digastric muscle. The average lengths of the mastoid segment of the facial nerve and the prebifurcation extracranial facial nerve are 16.35 +/- 1.21 mm and 18.93 +/- 1.41 mm, respectively. The average distance from the bifurcation of the facial nerve to the hypoglossal nerve turn is 31.56 +/- 2.53 mm. For a direct hypoglossal-facial nerve anastomosis, a length of approximately 19 mm of the hypoglossal nerve is required. For the interposition nerve graft technique, a 35 mm-long graft is required. For the technique using a longitudinally dissected hypoglossal nerve, an average length of 31.56 mm is required. Exposure of the facial nerve within the mastoid process drilling technique requires 16.35 mm of drilling. CONCLUSION This study attempts to establish the exact graft, dissection within the hypoglossal nerve, and mastoid drilling requirements for hypoglossal to facial nerve transfer.

Abstract
BACKGROUND The treatment of facial paralysis aims to recover symmetry in both static and dynamic states, which are seriously affected by the progressive contralateral hyperkinesis. Botulinum toxin may be used to reduce facial asymmetry in patients suffering from facial paralysis. METHODS Eighteen patients (12 female and six male patients) with facial palsy and contralateral hyperkinesis were injected with 112.5 units (0.9 ml) of Dysport (botulinum toxin type A) distributed evenly in the muscles of the perioral area. The patients were examined at 14, 28, 42, 56, 90, 150, and 180 days after the injection. Patients evaluated the degree of improvement at each time point. In addition, three evaluators made static (relaxed state) and dynamic (maximum contraction while smiling) assessments using a series of measurements obtained with a digital caliper, and the mean was used as the reference value. RESULTS The quantitative analysis demonstrated a significant reduction in hyperkinesis that lasted approximately 180 days. There was a significant or moderate improvement in most of the cases. All of the patients were very satisfied with the treatment. Adverse events were short-lived (mainly during the first 15 days) and related to difficulty in drinking without liquid loss (nine of 18) and difficulty in chewing without food loss (three of 18). CONCLUSION Injection of botulinum toxin was effective in reducing muscular hyperkinesis in the hemiface opposite that affected by facial paralysis, with mild and short-term side effects.

Abstract
BACKGROUND Facial nerve paralysis is a common event in patients with head and neck cancer or metastasis of cancer to the parotid region. The aim of this study was to evaluate the outcomes of periocular reconstruction for facial nerve paralysis in cancer patients. METHODS The medical records of all patients who had undergone periocular surgery for facial nerve paralysis between January of 1999 and December of 2003 were retrospectively reviewed. The outcome measures included the ocular symptoms and signs, improvement in symptoms of exposure keratopathy postoperatively, timing of periocular surgery in relation to radiotherapy, and surgical complications. RESULTS Preoperative symptoms included burning sensation (25 of 78 patients), difficulty with vision (30 of 78), frequent use of lubricating drops and ointments (52 of 78), and excessive tearing (37 of 78). The degree of lagophthalmos ranged from 1.5 to 12 mm (mean, 6.5 mm) preoperatively and from 0 to 4.5 mm (mean, 1.5 mm) postoperatively. Seventy-eight patients had gold weight placement; 72 of them also had lateral tarsorrhaphy, 56 had lower eyelid tightening via a lateral tarsal strip procedure in addition to the gold weight and lateral tarsorrhaphy, and 22 had brow elevation in addition to all the above-mentioned procedures. Four also required a medial tarsorrhaphy. All patients reported less dependence on lubricating drops and ointments after periocular surgery. Eighteen of 25 patients who had foreign body sensation as their main preoperative symptom experienced improvement after surgery. Forty-four patients had radiotherapy to the head and neck region. Twenty-seven patients completed radiotherapy before and 17 after periocular reconstruction. Complication rates were low and comparable in both preoperative and postoperative radiation groups. CONCLUSIONS Periocular reconstruction for facial paralysis results in improvement of exposure keratopathy and less dependence on lubricating drops and ointments. Complications are minimal and infrequent. The timing of external beam radiotherapy does not affect the outcomes of periocular surgery.

Abstract
✓ Increasing rates of facial and cochlear nerve preservation after vestibular schwannoma surgery have been achieved in the last 30 years. However, the management of a partially or completely damaged facial nerve remains an important issue. In such a case, several immediate or delayed repair techniques have been used.
On the basis of recent studies of successful end-to-side neurorrhaphy, the authors applied this technique in a patient with an anatomically preserved but partially injured facial nerve during vestibular schwannoma surgery. The authors interposed a sural nerve graft to reinforce the facial nerve whose partial anatomical continuity had been preserved. On follow-up examinations 18 months after surgery, satisfactory cosmetic results for facial nerve function were observed.
The end-to-side interposed nerve graft appears to be a reasonable alternative in cases of partial facial nerve injury, and might be a future therapeutic option for other cranial nerve injuries.

Abstract
OBJECT The aim of this study was to describe the symptomatology, radiological features, and surgical treatment of patients with cavernous angiomas within the internal auditory canal (IAC). METHODS The authors reviewed the cases of seven patients with cavernous angiomas in the IAC that had been surgically treated in the 22-year period between 1983 and 2005. All the patients had presented with sensorineural hearing loss, and four suffered from tinnitus. Four patients also reported facial symptoms such as hemispasm or progressive palsy; one of these patients had presented with sudden facial paresis due to intrameatal tumor hemorrhage. According to computed tomography (CT) results, the lesions caused enlargement of the IAC. Interestingly, these same angiomas showed variable features on magnetic resonance (MR) imaging, making their differentiation from intrameatal vestibular schwannomas (VSs) sometimes impossible. In all patients the lesions were totally removed via the suboccipital retrosigmoid approach. They could be dissected away from the facial nerve in five cases, whereas in two cases, because of the location of the lesion, the seventh cranial nerve had to be sectioned and repaired with a sural nerve graft. Transient worsening of seventh cranial nerve symptoms occurred in two patients, with postoperative improvement in each of them. The cochlear nerve could not be functionally preserved because of its extreme adherence to the tumor, although its continuity was preserved in four patients. Complete deafness was the only postoperative complication. CONCLUSIONS Cavernous angiomas of the IAC are very uncommon lesions that can imitate the symptoms of VSs. Although it is the most sensitive study available, MR imaging does not show sufficiently specific findings to differentiate the two lesion types. Thus, the preoperative diagnosis must be based on patient symptoms plus the CT and MR imaging features.

Abstract
Hypoglossal-facial anastomosis was performed in four patients with total peripheral facial palsy after removal of cerebellopontine tumors (three patients with neurinoma) and pontine aneurysm (one patient). The anastomosis was performed after a period of 3 months to one year from surgery. The results obtained, concerning the facial activity, were clinically valued according to the tests used (questionnary, and the House-Brackmann paralysis index); the EnOG was used for its electrophysiological assessment. The follow-up period was 4 years with a good facial recovery in three patients and poor in one (class V, 27% in ENoG). We observe that the improvement in function greatly depends on the early surgical process performance.

Abstract
The technique of facial nerve repair with side-to-end hypoglossal-facial anastomosis is presented and evaluated in five patients who were operated on for facial nerve paralysis after acoustic schwannoma surgery, or had cranial base trauma. The end-to-end hypoglossal-facial anastomosis is accompanied by hemilingual paralysis, with difficulty in swallowing, chewing and speaking. In this new technique, the facial nerve is mobilised in the temporal bone, transected at the second genu and transposed to the hypoglossal nerve where a tensionless side-to-end anastomosis is performed. The hypoglossal nerve is transected in oblique fashion to about one third of its circumference. We were able to achieve a tensionless anastomosis in all patients. The idea is to bring about re-innervation of the previously denervated tissue via a collateral sprouting of axons of the donor nerve through the site of coaptation without sacrificing the innervation of the donor nerve's original targets. With side-to-end hypoglossal-facial anastomosis, two patients attained a House- Brackmann grade of III (one of them with independent movement of eyelids and mouth); one achieved grade IV, another grade V and grade VI. No patient had hemilingual atrophy nor any problems associated with swallowing or chewing.

Abstract
OBJECTIVE Nerve regeneration through cold preserved nerve allografts is demonstrated, and treatment of nerve allografts with FK506 induces better regeneration than other immunosuppressants. We study nerve regeneration through cold preserved nerve allografts temporarily treated with FK506 and compare it with the regeneration obtained using classic nerve autografts in a facial paralysis model in monkeys. METHODS A trunk of the facial nerve on both sides was transected in eight monkeys and immediately repaired with a 3 to 4 cm nerve autograft or allograft. FK506 was administered to the animals of the allograft group for 2 months, and nerve allografts were cold preserved for 3 weeks. At periods of 3, 5, and 8 months after surgery, quantitative electrophysiological assessment and video recordings were performed. At the end of the study, quantitative analysis of neurons in the facial nucleus was carried out, and axons were stereologically counted. RESULTS After the regenerative period, neuronal density was higher in the autograft group. However, distal axonal counts were similar in both groups. Serial electrophysiological recordings and histology of nerve allografts showed that the grafts were partially rejected after cessation of the immunosuppressant. CONCLUSION The regeneration through nerve allografts temporarily treated with FK506 does not achieve the electrophysiological results and neuronal counts achieved with nerve autografts, but axonal collateralization in the allografts induces a similar activation of mimic muscles.

Abstract
Detailed knowledge of embryology, anatomy, and function of the facial nerve is essential in treating the devastating functional, aesthetic, and psychological sequelae of facial paralysis. Two basic factors influence the method of repair and the subsequent outcome of the effort to combat facial paralysis. First is the availability of a viable proximal nerve stump which can be used as the source for motor axons, and which is related to the level of the injury. Second is the duration of the paralysis, which will dictate the possibility of reinnervating the facial muscles. Early restoration of nerve continuity, and therefore reestablishment of the neuromuscular junction and preservation of the function of the facial muscles, lead to superior functional and aesthetic rehabilitation. Secondary reconstruction, after the establishment of atrophy of the motor endplates of the facial muscles, is possible with nerve grafts and microsurgical free functional muscle transfer. These techniques, although not perfect, greatly improve aesthetic balance and alleviate the functional and psychological implications of the paralysis.

Abstract
OBJECTIVES To compare the outcomes of three surgical techniques used in the rehabilitation of the paralyzed face. STUDY DESIGN Retrospective study. SETTING University-based tertiary referral center. PATIENTS Between 1976 and 2000, rehabilitative facial nerve surgery was performed on 70 adult patients with varying underlying diseases. INTERVENTION Three methods of facial nerve rehabilitative surgery were performed: end-to-end anastomosis, cable nerve graft interposition, and classic faciohypoglossal transposition. MAIN OUTCOME MEASURES The House-Brackmann grade was scored at 6, 12, 24, and 36 months by the two senior authors. A favorable outcome was defined as House-Brackmann Grade </= III. Other parameters recorded were repair technique, age, nerve rerouting, whether the repair was immediate or delayed, and the anatomic position of the nerve defect in relation to the geniculate ganglion. RESULTS Data were available on 66 patients (94%), of whom 13 had an end-to-end anastomosis, 25 a cable nerve graft interposition, and 28 a classic faciohypoglossal transposition. At 24 months, a House-Brackmann Grade </= III was achieved in 84.6% of those who underwent end-to-end anastomosis, 56.0% of those who underwent cable nerve graft interposition, and 25.0% of those who underwent classical faciohypoglossal transposition. End-to-end anastomosis and cable nerve graft interposition were superior to classic faciohypoglossal transposition (log-rank test, p = 0.0013). Twenty-five percent of all cases demonstrated improvement in House-Brackmann grade after 24 months. Increasing age at the time of repair was associated with a poorer outcome (p = 0.03 on logistic regression). CONCLUSION End-to-end anastomosis confers the best facial function, followed by cable nerve graft interposition and then classic faciohypoglossal transposition. Contrary to some previous opinions, improvement in facial function can still occur 2 years after surgical repair, particularly with classic faciohypoglossal transposition.

Abstract
Neurovascular free-muscle transfer for facial reanimation was performed as a secondary reconstructive procedure for 45 patients with facial paralysis resulting from ablative surgery in the parotid region. This intervention differs from neurovascular free-muscle transfer for treatment of established facial paralysis resulting from conditions such as congenital dysfunction, unresolved Bell palsy, Hunt syndrome, or intracranial morbidity, with difficulties including selection of recipient vessels and nerves, and requirements for soft-tissue augmentation. This article describes the authors' operative procedure for neurovascular free-muscle transfer after ablative surgery in the parotid region. Gracilis muscle (n = 24) or latissimus dorsi muscle (n = 21) was used for transfer. With gracilis transfer, recipient vessels comprised the superficial temporal vessels in 12 patients and the facial vessels in 12. For latissimus dorsi transfer, recipient vessels comprised the facial vessels in 16 patients and the superior thyroid artery and superior thyroid or internal jugular vein in four. Facial vessels on the contralateral side were used with interpositional graft of radial vessels in the remaining patient with latissimus dorsi transfer. Cross-face nerve grafting was performed before muscle transfer in 22 patients undergoing gracilis transfer. In the remaining two gracilis patients, the ipsilateral facial nerve stump was used as the primary recipient nerve. Dermal fat flap overlying the gracilis muscle was used for cheek augmentation in one patient. In the other 23 patients, only the gracilis muscle was used. With latissimus dorsi transfer, the ipsilateral facial nerve stump was used as the recipient nerve in three patients, and a cross-face nerve graft was selected as the recipient nerve in six. The contralateral facial nerve was selected as the recipient nerve in 12 patients, and a thoracodorsal nerve from the latissimus dorsi muscle segment was crossed through the upper lip to the primary recipient branches. A soft-tissue flap was transferred simultaneously with the latissimus muscle segment in three patients. Contraction of grafted muscle was not observed in two patients with gracilis transfer and in three patients with latissimus dorsi transfer. In one patient with gracilis transfer and one patient with latissimus dorsi transfer, acquired muscle contraction was excessive, resulting in unnatural smile animation. The recipient nerves for both of these patients were the ipsilateral facial nerve stumps, which were dissected by opening the facial nerve canal in the mastoid process. From the standpoint of operative technique, the one-stage transfer for latissimus dorsi muscle appears superior. Namely, a combined soft-tissue flap can provide sufficient augmentation for depression of the parotid region following wide resection. A long vascular stalk of thoracodorsal vessels is also useful for anastomosis, with recipient vessels available after extensive ablation and neck dissection.

Abstract
PURPOSE OF REVIEW The face is the mirror of personality. Facial expression is the most important part of verbal and nonverbal communication. Patients with head and neck neoplasm and facial palsy are more stigmatized by the latter than by the tumor itself. Facial nerve reconstruction in such a patient is a great challenge. This review gives an overview of the assessment of facial palsy, surgical reconstruction, and postoperative treatment. RECENT FINDINGS MRI, CT, and electromyography are indispensable tools in the assessment of preoperative facial palsy in patients with head and neck neoplasm. When part of the facial nerve has to be sacrificed during surgery, the best functional results are achieved with direct facial nerve suture, interposition graft, or by a hypoglossal-facial nerve interposition jump anastomosis. The latter is the best choice when the reanimation is planned between 6 months and 2 years after tumor surgery. In any case, the eye is best rehabilitated with upper lid loading. Temporalis muscle transposition gives fast and good results for the restoration of the corner of the mouth after radical surgery. Reanimation by free muscle transfer for head and neck cancer patients is rarely indicated. Botulinum toxin treatment is an excellent postoperative aid for refining the result; the optimal modality of postoperative physiotherapy is still unclear. SUMMARY Surgical reanimation of the face in head and neck patients has reached a high standard. Strategies to decrease misdirected reinnervation after nerve suture have to be established in clinical practice for further improvement of facial rehabilitation.

Abstract
Despite advances in neuro-otological techniques permanent complete facial palsy may still occur in up to 10% of patients undergoing removal of cerebellopontine angle tumours. Hypoglossal-facial nerve anastomosis is the procedure of choice in our unit for facial reanimation in such patients and below we report the results of hypoglossal-facial nerve anastomosis performed on 29 patients. Assessment of patient benefit from hypoglossal-facial nerve anastomosis was obtained using a questionnaire based on the Glasgow Benefit Inventory. The results showed all patients to have an improvement in their House Brackmann grade following hypoglossal-facial anastomosis with 65% achieving grade III or better. Of the 20 patients who completed the questionnaire, 18 showed a positive benefit (median score 59.5, range 40-77). There was a significant correlation (P < 0.045) between the Glasgow benefit inventory score and House Brackmann grade. Outcome was not affected by the time interval between the acoustic neuroma surgery and performing the hypoglossal-facial nerve anastomosis, sex or length of follow-up. However the Glasgow benefit score was significantly influenced by age (P = 0.023) with younger patients showing more benefit independent of improvement in facial nerve function.

Abstract
OBJECT Hypoglossal nerve (12th cranial nerve) transfer was performed to treat the sequelae of brachial plexus root avulsion in 12 adults and two infants, and the patients were followed to assess the effectiveness of the surgery. METHODS The 12th cranial nerve was transected at the base of the tongue, and a sural nerve graft was used to bridge the gap between the donor (12th) and recipient nerves: C-5 spinal, axillary, suprascapular, or musculocutaneous nerve. The mean graft length in adult patients was 15.75 +/- 5.5 cm (+/- standard deviation, median 14.5 cm) and in the two infants the graft lengths were 7 and 8 cm, respectively. After a mean postoperative interval of 1138 +/- 254 days, electromyographic examination of the target muscles showed tongue movement-related activity in all patients. Muscle force strength measured according to the Medical Research Council's guidelines, was Grade 3 or higher in 21% of patients. Contraction, however, could only be attained by tongue movements, and volitional control was not achieved. CONCLUSIONS Although recovery of muscle strength was obtained by 12th cranial nerve transfer, the functional gain remained virtually nonexistent because central control was missing.

Abstract
OBJECT In this study the authors investigated the histomorphometric background and microsurgical anatomy associated with surgically created direct hypoglossal-facial nerve side-to-end communication or nerve "anastomosis." METHODS Histomorphometric analyses of the facial and hypoglossal nerves were performed using 24 cadaveric specimens and three surgically obtained specimens of severed facial nerve. Both the hypoglossal nerve at the level of the atlas and the facial nerve just distal to the external genu were monofascicular. The number of myelinated axons in the facial nerve (7228 +/- 950) was 73.2% of those in the normal hypoglossal nerve (9778 +/- 1516). Myelinated fibers in injured facial nerves were remarkably decreased in number. The cross-sectioned area of the normal facial nerve (0.948 mm2) accounted for 61.5% of the area of the hypoglossal nerve (1.541 mm2), whereas that of the injured facial nerve (0.66 mm2) was less than 50% of the area of the hypoglossal nerve. Surgical dissection and morphometric measurements were performed using 18 sides of 11 adult cadaver heads. The length of the facial nerve from the pes anserinus to the external genu ranged from 22 to 42 mm (mean 30.5 +/- 4.4 mm). The distance from the pes anserinus to the nearest point on the hypoglossal nerve ranged from 14 to 22 mm (mean 17.3 +/- 2.5 mm). The former was always longer than the latter; the excess ranged from 6 to 20 mm (mean 13.1 +/- 3.4 mm). Surgical anatomy and procedures used to accomplish the nerve connection are described. CONCLUSIONS The size of a half-cut end of the hypoglossal nerve matches a cut end of the injured facial nerve very well. By using the technique described, a length of facial nerve sufficient to achieve a tensionless communication can consistently be obtained.
