RESUMO
El síndrome de Moebius es una enfermedad congénita poco común que se caracteriza por el compromiso unilateral o bilateral del VI y VII par craneal, lo que compromete los músculos que controlan la oculomotricidad, produciendo una parálisis en la abducción del globo ocular y los músculos involucrados en la expresión facial. Su presentación clínica y grados de severidad son variables, puede presentar compromiso simétrico o asimétrico. Adicionalmente, gran parte de los casos se relacionan con trastornos del lenguaje, anomalías musculoesqueléticas y orofaciales. En el presente artículo se presenta el caso de una paciente femenina de 3 años producto de un embarazo trigemelar con diagnóstico clínico de síndrome de Moebius al nacer, confirmado por neuroimagen en la que se evidencia la ausencia bilateral del nervio facial en ángulos pontocerebelosos, adicionalmente con un defecto completo en los movimientos oculares de abducción y aducción lo que impide el estrabismo convergente común en estos pacientes.
Moebius syndrome is a rare congenital disease characterized by unilateral or bilateral involvement of the VI and VII cranial nerves, which compromises the muscles that control ocular motricity with paralysis in the abduction of the eyeball and the muscles involved in the facial expression. Its clinical presentation and degrees of severity are variable, and it can be symmetric or asymmetric. Additionally, most of the cases are related to language disorders, musculoskeletal and orofacial anomalies. This paper presents the case of a 3-year-old female patient, product of a trigemellar pregnancy with a clinical diagnosis of Moebius syndrome at birth, confirmed by neuroimaging, which shows the bilateral absence of the facial nerve in point-lateral angles. Additionally she has a complete defect in abduction and adduction eye movements, which prevents the common convergent strabismus in these patients.
A síndrome de Moebius é uma doença congênita rara caracterizada pelo envolvimento unilateral ou bilateral dos nervos cranianos VI e VII, que compromete os músculos que controlam a oculomotricidade com paralisia na abdução do globo ocular e dos músculos envolvidos na expressão facial. Sua apresentação clínica e graus de gravidade são variáveis, podendo ser um comprometimento simétrico ou assimétrico. Além disso, a maioria dos casos está relacionada a distúrbios de linguagem, anomalias musculoesqueléticas e orofaciais. Este paper apresenta o caso de uma paciente de 3 anos de idade, fruto de uma gravidez trigêmea com diagnóstico clínico de Síndrome de Moebius ao nascimento, confirmado por neuroimagem em que é evidente a ausência bilateral do nervo facial nos ângulos ponto-cerebelares. Além disso, ela tem um defeito completo nos movimentos oculares de abdução e adução, o que impede o estrabismo convergente comum nesses pacientes.

El schwannoma es una patología rara del nervio facial. Su diagnóstico preoperatorio es dificultoso dado que no tiene síntomas ni signos patognomónico de la enfermedad. La disección del nervio facial en su tronco y sus ramas con electroestimulacion es la forma de quirúrgica de sospecharlo intraoperatoriamente. La descompresión parcial o exeresis completa deberá ser considerado de acuerdo a la experiencia del equipo quirúrgico en reconstrucción nerviosa. La reparación del nervio facial como primera opción debe el injerto inmediato o sutura termino terminal. La neurotización es un procedimiento quirúrgico que le provoca al paciente simetría facial con manejo de oclusión ocular y manejo de comisura bucal, debe ser realizado antes del año de la injuria nerviosa. La rehabilitación del nervio facial necesita de un equipo multidisciplinario y la colaboración permanente del paciente para conseguir los objetivos propuestos.
Schwannoma is a rare pathology of the facial nerve. Its preoperative diagnosis is difficult since it has no symptoms or pathognomonic signs of the disease. The dissection of the facial nerve in its trunk and its branches with electrostimulation is the surgical way to suspect it intraoperatively. Partial decompression or complete exeresis should be considered according to the experience of the surgical team in nerve reconstruction. The repair of the facial nerve as a first option should be the immediate graft or end-to-end suture. Neurotization is a surgical procedure that causes the patient facial symmetry with management of ocular occlusion and management of the corner of the mouth, it must be performed within a year of the nerve injury. The rehabilitation of the facial nerve requires a multidisciplinary team and the permanent collaboration of the patient to achieve the proposed objectives.

Abstract: Burning mouth syndrome (BMS) is a chronic intraoral pain state that has been described as burning pain, tingling or numbness in the oral mucosa, in the absence of any organic disease. Most often affecting the tongue, anterior palate, and/or lips. The diagnosis of primary BMS is purely clinical and based on patients' description of typical subjective symptoms as well on the exclusion of any systemic or local factors that may give rise to secondary burning pain sensations within the oral mucosa. Relevant studies links BMS to a peripheral neuropathy and BMS patients have revealed distinct abnormalities within the trigeminofacial large and small fiber systems and the trigeminal brainstem complex. Therefore, treatment approach should involve a multidisciplinary character similar to the treatment for neuropathic pain including factors that might also play a role on the BMS etiology and pathophysiology.
Resumen: El síndrome de la boca ardiente (SBA) es un estado crónico de dolor intraoral descrito por pacientes como dolor o sensación quemante, de cosquilleo o adormecimiento de la mucosa oral, con ausencia de lesiones visibles en la boca. Puede afectar la lengua, el paladar anterior y o los labios. Su diagnóstico es basado en la típica descripción subjetiva del paciente, excluyendo cualquier otro factor sistémico o local que podría provocar cualquier otra sensación quemante dentro de la mucosa oral. Estudios relevantes han mostrado que SBA primario parece tener una patofisiología de origen de tipo neuropático donde pacientes con SBA pueden presentar distintas anormalidades en el complejo trigeminal a nivel de las fibras sensoriales delgadas y gruesas. Por tanto, el tratamiento y manejo de estos pacientes debe ser de la misma manera multidisciplinaria como en el caso con el dolor neuropático, sin olvidar incluir el manejo de todos los factores que podrían intervenir en la etiología del SBA.

Xiaoxuming Decoction is an ancient classic herbal formula for the treatment of stroke. In ancient times, the connotation of stroke was very extensive, including facial neuritis, acute cerebral infarction, acute cerebral hemorrhage, sequelae of cerebral hemorrhage, unexplained weakness of limbs, cervical spondylosis, acute myelitis, acute radiculitis, Guillain Barre syndrome, multiple sclerosis, myasthenia gravis, motor neuron disease, dermatomyositis, hypokalemic paralysis peripheral neuritis. It has been identified that: ①Xiaoxuming Decoction is very common in the treatment of cerebrovascular diseases, such as cerebral infarction, cerebral hemorrhage and other cerebrovascular diseases, facial neuritis, acute myelitis, acute radiculitis, Guillain Barre syndrome, unexplained limb weakness, multiple sclerosis, motor neuron disease, myasthenia gravis, and rheumatic and immune system diseases, such as dermatomyositis, and can not only alleviate symptoms, but also improve prognosis and the long-term survival rate. ②Sudden limb failure, facial paralysis, and hypoalgesia without heat syndrome are the key indications of Xiaoxuming Decoction. ③This is a special prescription for the treatment of acute facial neuritis, and can cure in one week in the combination with moxibustion. ④In the treatment of facial neuritis complicated with hypertension or acute cerebrovascular disease, Xiaoxuming Decoction generally has a certain antihypertensive effect, without any hypertensive effect, which reflected its two-way regulatory effect for blood pressure. ⑤In the treatment of unknown limb weakness, acute myelitis, acute radiculitis, Guillain Barre syndrome, Xiaoxuming Decoction can rapidly alleviate the symptoms. ⑥This is the basic formula for multiple sclerosis and motor neuron disease. Long term use of Xiaoxuming Decoction can alleviate the symptom of limb weakness, reduce the occurrence of complications and delay the progress of the disease, but with a poor long-term prognosis. ⑦In the treatment of myasthenia gravis, Xiaoxuming Decoction can significantly improve muscle strength, and gradually help stop hormone reduction. After thymoma surgery, Xiaoxuming Decoction is also applicable to some patients with recurrent myasthenia gravis. ⑧Xiaoxuming Decoction also plays a role in the treatment of dermatomyositis and cervical spondylopathy. ⑨Raw ephedra is the monarch drug of Xiaoxuming Decoction, which is the key to the effect. The dosage starts with 6 g is titrated in a small dose and increases gradually. In addition, this formula is forbidden for those with red face, fast heart rate, high blood pressure, blocked stool, red tongue, yellow fur, wiry and rapid pulse or powerful pulse, and spout pulse.

Painful post-traumatic trigeminal neuropathy (PTTN) involves spontaneous and evoked pain, of moderate to severe intensity, continuous and described as burning or shooting. The first line treatment is pharmacological. However, botulinum toxin - A (BoNT-A) can be used when medications cannot control pain. This article describes the use of BoNT-A in a case of PTTN refractory to conventional pharmacological treatment. A 44-year-old male patient presented with an 8-years history of pain in the lower left second molar region. Pain was burning, lasting for seconds, with multiple pain episodes per day. Diagnosis hypothesis was PTTN. After no improvement with conventional pharmacological treatment, injections of BoNT-A were elected. Somatosensory assessment showed a significant reduction in visual analog scale for touch, cold and pinprick sensitivity. Likewise, patient's impression of change in pain significantly improved after BoNT-A injections. Our results suggest that BoNT-A could be used as a treatment for PTTN refractory to conventional treatments. (AU)
A neuropatia trigeminal pós-traumática dolorosa (PTTN) envolve dor espontânea e evocada, de intensidade moderada a grave, contínua e descrita como queimante ou lascinante. O tratamento de primeira linha é farmacológico. No entanto, a toxina botulínica - A (BoNT-A) pode ser usada quando os medicamentos não conseguem controlar a dor. Este artigo descreve o uso da BoNT-A em um caso de PTTN refratário ao tratamento farmacológico convencional. Paciente de sexo masculino, 44 anos, com 8 anos de dor na região do segundo molar inferior esquerdo. A dor foi descrita como queimante, com duração de segundos e com vários episódios por dia. A hipótese de diagnóstico foi PTTN. Após nenhuma melhora com o tratamento farmacológico convencional, as injeções de BoNT-A foram eleitas. A avaliação somatossensorial mostrou uma redução significativa na escala visual analógica para sensibilidade ao toque, frio e picada após BoNT-A. Da mesma forma, a impressão de mudança do paciente na dor melhorou significativamente após as injeções de BoNT-A. Nossos resultados sugerem que o BoNT-A poderia ser usada como tratamento para PTTN refratário a tratamentos convencionais. (AU)

Abstract Introduction: Otitis media, mastoiditis or the pressure effect of tumorous lesions such as cholesteatoma can be the cause of facial canal dehiscence and facial nerve paralysis. The most common segment involved in dehiscence is the tympanic segment and the second most common is the lateral aspect of the facial canal in the oval window area. Objective: To determine the prevalence of the facial canal dehiscence and the relationship between the angle at the second genu of the facial nerve and facial canal dehiscence. Methods: We evaluated the surgical findings in 113 patients who underwent surgery for cholesteatoma. Facial canal dehiscence was detected in 62 of the 113 patients. Patients were divided into two groups: Group 1, with dehiscence of the facial canal and Group 2, without dehiscence of the facial canal. Results: The mean angles at the second genu of the facial nerve in Groups 1 and 2 were 117.8º ± 9.63º and 114º ± 9.9º, respectively. There was a statistically significant difference between the mean angles at the second genu for the two groups (p = 0.04). Conclusion: In patients with dehiscence of the facial canal, the angle at the second genu was found to be wider than those without dehiscence.
Resumo Introdução: Otite média, mastoidite ou a compressão por lesões tumorais como o colesteatoma podem ser a causa da deiscência do canal facial e paralisia do nervo facial. A deiscência ocorre mais frequentemente no segmento timpânico, seguido do aspecto lateral do canal facial na área da janela oval. Objetivo: Determinar a prevalência da deiscência do canal facial e sua relação com o ângulo no segundo joelho do nervo facial. Método: Avaliamos os achados cirúrgicos para detecção de deiscência do canal facial em 113 pacientes submetidos à cirurgia de colesteatoma. A deiscência do canal facial foi observada em 62. Os pacientes foram divididos em dois grupos: Grupo 1, com deiscência do canal facial, e Grupo 2, sem deiscência do canal facial. Resultados: Os ângulos médios no segundo joelho do nervo facial nos grupos 1 e 2 foram 117,8º ± 9,63º e 114º ± 9,9º, respectivamente. Houve diferença estatisticamente significante entre os ângulos médios no segundo joelho para os dois grupos (p = 0,04). Conclusão: Em pacientes com deiscência no canal facial, foi observado que o ângulo do segundo joelho era maior do que naqueles sem deiscência.

OBJECTIVE@#To observe the effect of different acupuncture intervention time on the improvement of the symptoms of acute facial neuritis and the length of recovery time, and to find the best interventional opportunity for acute facial neuritis.@*METHODS@#A total of 120 patients with acute facial neuritis (all unilateral onset) were randomly divided into 4 groups, namely group A, group B, group C and group D, 30 cases in each group. Acupuncture performed within 3 days after onset in the group A; oral mecobalamin dispersible tablets and multivitamin B tablets were received within 3 days after onset, and acupuncture was started from the 4th day in the group B; oral mecobalamin dispersible tablets and multivitamin B tablets were given within 5 days after onset, and acupuncture was administered from the 6th day in the group C; oral mecobalamin dispersible tablets and multivitamin B tablets were given within 7 days after onset, and acupuncture was applied from the 8th day in the group D. Penetration needling was the main acupuncture treatment, with infrared radiation on the cheeks, once a day, 6 days a week and 3 weeks were given. After treatment, the symptom scores (Portmann scores) of the 7th, 14th and 28th day after onset were compared. The time of improvement and the clinical effect of each group were compared.@*RESULTS@#On the 7th, 14th and 28th day after onset, the Portmann scores of the 4 groups were higher than those before treatment (all <0.05). On the 7th, 14th and 28th day after onset, the Portmann scores in the group A were higher than those in the other 3 groups (all <0.05). There was significant difference between both pairs of group B, group C and group D (all <0.05). The total effective rate in the group A was 96.7% (29/30), which was higher than 93.3% (28/30), 86.7% (26/30) and 83.3% (25/30) in the other 3 groups (all <0.05). The difference between the 4 groups in the beginning of improvement, significant improvement time and clinical recovery time was statistically significant (all <0.05), and the group A was optimal.@*CONCLUSION@#Early intervention of acupuncture with acute facial neuritis can appropriately slow the progression of facial nerve injury, improve the therapeutic effect, and shorten the clinical recovery time.

ABSTRACT Facial nerve hemangioma is a rare and benign vascular tumor, and accounts for 0.7% of intratemporal tumors. We report the second case described in the literature of a facial nerve hemangioma in its tympanic segment. A 14-year-old male patient presented with a history of progressive right ear hearing loss with preserved facial mimicry. Pure tone audiometry showed a right ear moderate conductive hearing loss. Magnetic resonance imaging demonstrated an expansive lesion involving the tympanic segment of the right facial nerve, suggestive of hemangioma. Watchful waiting was chosen as management. In the first case of middle ear facial hemangioma described in the literature, facial palsy was the symptom that led the patient to seek medical care. In the present case, it can be inferred that the first symptom was conductive hearing loss ipsilateral to the lesion. Facial palsy may not be present and the clinical presentation may resemble otosclerosis, ossicular chain disruption, and third window abnormalities, among other differential diagnoses of conductive hearing loss. The second case of tympanic portion facial nerve hemangioma is reported, describing the specificity of conductive hearing loss as its only clinical manifestation.
RESUMO O hemangioma do nervo facial é um tumor vascular raro e benigno, que corresponde a 0,7% dos tumores intratemporais. Apresentamos o segundo caso descrito na literatura de hemangioma do nervo facial em sua porção timpânica. Paciente de 14 anos, sexo masculino, apresentando hipoacusia progressiva em orelha direita com mímica facial preservada. A audiometria evidenciou perda condutiva moderada à direita. A ressonância magnética demonstrou lesão expansiva, comprometendo o segmento timpânico do nervo facial direito, sugestiva de hemangioma do nervo facial. A conduta foi expectante. No primeiro caso descrito na literatura de hemangioma do facial em orelha média, o sintoma que levou o paciente ao atendimento médico foi paralisia facial. No presente caso, pode-se inferir que o primeiro sintoma foi a perda auditiva condutiva ipsilateral à lesão. A paralisia facial pode não estar presente, e o quadro clínico pode se assemelhar à otosclerose, disjunção de cadeia e síndrome da terceira janela, dentre outros diagnósticos diferenciais de perdas auditivas condutivas. O artigo relata o segundo caso de hemangioma do nervo facial em sua porção timpânica, mostrando a peculiaridade de perda auditiva condutiva como única manifestação clínica.

Bell's palsy is an acute-onset unilateral peripheral facial neuropathy. For patients with sequelae of facial paresis, the successful rehabilitation of fully edentulous arches is challenging. This case report described the treatment procedures and clinical considerations to fabricate complete dentures of a patient who showed unilateral displacement of mandible, unilateral chewing pattern and parafunctional jaw movement due to sequelae of Bell's palsy. Gothic arch tracing was used to record reproducible centric relation and lingualized occlusion was performed to provide freedom to move between centric relation and the patient's habitual functional area in fabricating satisfactory dentures in terms of function and esthetics.

A 25-years-old woman with mandibular prognathism underwent a mandibular setback by way of mandibular sagittal split ramus osteotomy (MSSRO). After 2 days of operation, she developed difficulty of closing her right eye. The blink reflex test and motor nerve conduction study of the right orbicularis oris muscle were revealed right facial neuropathy of unknown origin and House-Brackmann facial nerve grading system (HBFNGS) grade V. For treatment, we initially prescribed oral prednisolone and nimodipine including physical therapy. The samples consisted of 11 facial nerve palsy patients caused by MSSRO and were analysed about onset of facial nerve palsy, postoperative HBFNGS, final HBFNGS, treatment method and recovery time. At 10 weeks of treatment of nimodipine, she had completely regained normal function (HBFNGS grade I) of the right facial nerve. The clinical results lead to assume a fast recovery of facial nerve function by the nimodipine medication, whereas average time of recovery is 16.32 weeks in references. Despite of the limited one patient treated, the result was very promising with respect to a faster recovery of the facial nerve function. Considering the use of nimodipine treatment for peripheral facial nerve palsy following a surgical approach with an anatomically preserved nerve can be recommended.

<p><b>OBJECTIVE</b>To determine the effect of AQP1 gene on facial nerve edema following injury through investigation of the relationship between the expression of AQP1 gene and Schwann cells swelling.</p><p><b>METHODS</b>The AQP1 expression in Schwann cells of mouse facial nerve tissues was detected by immunofluorescent staining. The transgenic protocol by lentivirus transduction was used to specifically upregulate AQP1 expression in Schwann cells. Lenti-AQP1 and CTRL (empty vector) transduced cells were observed during gene overexpression every 24 h for 6 days by using phase contrast microscopy. Cell volume of CTRL and Lenti-AQP1 treated cells was measured daily from the day of treatment, through day 6.</p><p><b>RESULTS</b>Schwann cell primary cultures maintained a high level of AQP1 water channels, representing an ideal cell model to study the role of AQP1 in the facial nerve. The expression of AQP1 mRNA and protein in Schwann cells infected with the Lenti-AQP1 was increased significantly compared with CTRL lentivirus (P < 0.05). Lenti-AQP1 caused cell swelling in cultured Schwann cells, as validated by cell volume determinations (P < 0.01).</p><p><b>CONCLUSIONS</b>AQP1 is an important factor responsible for the fast water transport of cultured Schwann cells. It plays an important role in facial nerve edema.</p>

Bilateral facial palsy, which is usually combined with other diseases, occurs infrequently. It may imply a life-threatening condition. Therefore, the differential diagnosis of bilateral facial palsy is important. However, the etiology is variable, which makes diagnosis challenging. We report a rare case of progressive bilateral facial palsy as a manifestation of granulomatosis with polyangiitis (GPA). A 40-year-old male with otitis media and right facial palsy was referred for electroneurography (ENoG), which showed a 7.7% ENoG. Left facial palsy occurred after 2 weeks, and multiple cavitary opacities were noted on chest images. GPA was diagnosed by lung biopsy. His symptoms deteriorated and mononeuropathy multiplex developed. The possibility of systemic disease, such as GPA, should be considered in patients presenting with bilateral facial palsy, the differential diagnosis of which is summarized in this report.

OBJECTIVE@#10 summarize tne clinical features of the facial nerve tumors involving the internal auditory canal and promote the management of facial nerve tumor.@*METHOD@#We retrospectively reviewed the clinical manifestations, the experiences of diagnosis and treatment of the facial nerve tumor involving the internal auditory canal. All these 5 cases were enrolled during January 2013 to Apr 2015.@*RESULT@#Among the 5 cases, 3 cases were facial neurilemmoma and the others were facial neurofibroma. The main symptoms of facial nerve tumors involving the internal auditory canal most commonly were facial paralysis companied with hearing loss. All the patients accepted the surgical treatment with various approaches, 3 cases of translabyrinthine approach, 1 case of middle fossa approach, and 1 case of combination of translabyrinthine and transotic approach. Total tumor resection were achieved in all 5 cases. Facial-hypoglossal nerve anastomosis was performed in one case, another case was undergone great auricular nerve graft.@*CONCLUSION@#Surgical intervention for patients with facial neuroma involving internal auditory canal should be considered when facial weakness has deteriorated to grade 4. The management should be based on the patient's hearing, facial nerve function, tumor size and invasive extension to select the appropriate surgical procedures.

Introdução: O espasmo hemifacial (EHF) caracteriza-se por movimento tônico-clônico involuntário da musculatura de uma hemiface. O tratamento tem sido realizado com aplicação de toxina botulínica (TxB). A aplicação unilateral classicamente descrita resulta em assimetria semelhante à paralisia facial. O objetivo desse trabalho foi normatizar o tratamento do EHF bilateralmente com TxB, a fim de prevenir a ocorrência de assimetria facial iatrogênica. Método: Foram analisadas 66 aplicações em 15 pacientes, seguindo o protocolo do serviço para paralisia facial, acrescentado de pontos pré-tarsais no lado com EHF. Foi feita dose complementar na reavaliação após 15 dias nos pacientes que apresentavam algum grau residual de espasmo ou assimetria, buscando-se a dose necessária para alcançar controle satisfatório do espasmo sem causar assimetria facial. Resultados: A dose média total foi 20,2 U do lado não acometido e 28,4 U do lado acometido, totalizando 48,6 U por aplicação. Houve diferença significante entre as hemifaces na dose para os músculos zigomático, orbicular da boca e orbicular dos olhos. Conclusões: A técnica proposta de aplicação bilateral de TxB controlou adequadamente o EHF e evitou assimetria iatrogênica. Como regra geral, a aplicação deve ser feita na proporção de 1:1,5 U no orbicular dos olhos (porção lateral) e 1:2 U no orbicular da boca. Nos demais músculos, a dose nos dois lados deve ser a mesma, realizando-se dose de reforço em 15 dias caso permaneça algum grau de espasmo. O único local com pontos exclusivos do lado acometido é a região pré-tarsal do músculo orbicular do olho.
Introduction: Hemifacial spasm (HFS) is characterized by the involuntary tonic-clonic movement of the muscles of the hemiface. It is usually treated with botulinum toxin (BTX). The classically described unilateral application of BTX results in an asymmetry similar to facial paralysis. The aim of this study was to standardize the treatment of HFS by applying BTX bilaterally to prevent the occurrence of iatrogenic facial asymmetry. Methods: The outcomes of 66 applications in 15 patients were analyzed according to the protocol of the facial paralysis service, to which pretarsal sites were added on the HFS side. On reassessment 15 days later, a complementary dose was administered to patients who exhibited some residual degree of spasm or asymmetry with the aim of determining the dose required to achieve satisfactory spasm control without causing facial asymmetry. Results: The total mean dose was 20.2 U at the contralateral side and 28.4 U at the spasm side (a total dose of 48.6 U per application). There was a significant difference between the doses applied to the zygomaticus, orbicularis oris, and orbicular oculi muscles on each hemiface . Conclusions: The proposed bilateral BTX application technique was effective in controlling HFS and prevented iatrogenic asymmetry. In general, application should be performed at a ratio of 1:1.5 U in the orbicularis oculi (lateral portion) and 1:2 U in the orbicularis oris. In the remaining muscles, the same dose should be administered on both sides and an additional dose can be applied 15 days later if some degree of spasm is present. The pretarsal region of the orbicularis oculi muscle is the only area for which BTX application on the healthy side is unnecessary.

Herpes zoster oticus, traditionally known as Ramsay Hunt syndrome, is nowadays described also as acute peripheral facial neuropathy by varicella zoster virus infection. Besides facial palsy, auricular vesicular eruptions accompanied by neuralgic pain, adjacent cranial nerve structures are involved and various audiovestibular symptoms are frequently combined. Early proper treatment strategies are required to get the favorable outcome and reduce the morbidity of neurocranial deficits of this syndrome.

OBJECTIVE@#To heighten the awareness of the facial nerve tumors.@*METHOD@#The clinical data of twenty-three patients complaining of facial paralysis who were diagnosed postoperatively as facial nerve tumors were analyzed. The hearing assessment of all patients was based on pure tone audiometry at the frequency of 0. 5, 1, 2, 4 kHz. Temporal bone high resolution CT scan and temporal bone MRI with gadolinium enhancement were conducted on all patients. Facial nerve function was assessed with the House-Brackmann (HB) grading system. Facial electroneurography (ENoG) was conducted on 20 patients to quantify the degree of nerve degeneration preoperatively. The pathological types of tumor were determined by postoperative pathological reports.@*RESULT@#Nineteen out of 23 cases presented hearing loss (82.6%), 10 cases suffered from tinnitus (43.5%), otalgia (17.4%) affected 4 cases, 3 cases manifested otorrhea (13.0%), and 2 cases presented vertigo (8.7%). Geniculate ganglion was the most commonly involved site (20 cases, 87.0%), followed by tympanic segments (18 cases, 78.3%), pyramid segment (16 cases, 69.6%), mastoid segment (10 cases, 43.5%), labyrinthine segment (9 cases, 39.1%), internal auditory canal segment and parotid gland segment (5 cases, 21.7%, respectively). Twenty-one cases (91.3%) of schwannomas, 1 case (4.3%) of neurofibroma and 1 case (4.3%) of hemangiomas were identified with histopathology postoperatively. The tumors were all completely excised, and the facial nerve function could recovered to HB III at the best after facial nerve repairment.@*CONCLUSION@#Facial nerve tumor is a rare and often misdiagnosed disease which was commonly manifested as facial nerve paralysis. Temporal bone CT and MRI can help to clarify the diagnosis preoperatively. Pure tone audiometry and electroneurography also plays a some certain roles in the diagnosis of facial nerve tumors. The tumors should be completely resected and the surgical approaches were determined based on tumor size, facial nerve function and preoperative auditory function.
