Comparison between early and delayed facial nerve decompression in traumatic facial nerve paralysis - A retrospective study

ABSTRACT Purpose To study the intraoperative findings in case of early and delayed decompression of facial nerve paralysis and compare their results. Methods Retrospective data analysis of 23 cases of longitudinal temporal bone fracture with House-Brackmann grade V and VI facial nerve paralysis. All cases were thoroughly evaluated and underwent facial nerve decompression through the transmastoid approach. All cases were under regular follow-up till the date of manuscript submission. Results Clinical improvement of the facial nerve function was observed for early vs. delayed facial nerve decompression. In the early decompression group, facial nerve function improved to grade II in eight cases (80%) and grade III in two cases (20%), whereas in the delayed decompression group it improved to grade II in one case (7.70%), grade III in four cases (30.76%), grade IV in seven cases (53.84%), and grade V in one case (7.70%). Conclusions Early decompression of facial nerve provides better results than delayed decompression because it enables early expansion of the nerve.

Anatomía aplicada a fracturas de temporal: análisis de 10 casos / Applied anatomy of a temporary fracture: analysis of 10 cases / Anatomia aplicada a fraturas de temporal: análise de dez caso

Antecedentes: las lesiones en el hueso temporal ocurren en el 30 a 70% de los casos de traumatismo de cráneo cerrado, siendo los accidentes automovilísticos causa del 31%. En general, las líneas de fractura corren paralelas a la línea del golpe entregado y se extienden a través de los agujeros de la base del cráneo, puntos débiles del hueso temporal. Estas se denominan como longitudinal o transversal, a pesar de que la mayoría son en realidad mixtas. Las fracturas bilaterales tienen una incidencia menor de 8-29%. Objetivo: Analizar los tipos de fracturas temporales más frecuentes y las modificaciones de éstas sobre su anatomía en correlación con la clínica del paciente y los exámenes de TAC. Diseño: Retrospectivo de corte transversal. Población: Niños y adultos jóvenes de ambos sexos. Método: Es un trabajo retrospectivo transversal con revisión de historias clínicas de niños y adultos jóvenes, más disecciones microanatómicas en cadáveres adultos de ambos sexos, fijados en formol al 10%. Resultados: Se recolectaron 10 pacientes; 8 de sexo masculino y 2 femeninos, del total 2 son niños. Todos con procedencia de Córdoba, consultan por zumbido, hipoacusia y mareo o desequilibrio postraumático. Uno de ellos niño de 13 años con hipoacusia bilateral y supuración de oído. Al grupo se suma una parálisis facial recuperada con tratamiento clínico. Conclusiones: El conocimiento de la anatomía, con el apoyo de la tomografía computada de oído, y los estudios audiológicos son fundamentales para el diagnóstico clínico y topográfico de la lesión.

Background: lesions occur in the temporal bone in the 30 to 70% of cases of closed skull trauma. Being car accidents cause 31%. In general, the fracture lines run parallel to the line of blow delivered and extend through the holes to the skull base, temporal bone weak points. These are denominate as longitudinal or transverseal, though most are actually mixed. The bilateral fractures have a lower incidence of 8-29%. Objetive: analize the types of temporal fractures the most frequent and modifications of these on their anatomy correlated with the patient’s clinical and computed tomography exams. Design: transversal cut retrospective. Population: children and young adults of both sexes. Method: it is a transversal retrospective study with review of clinical records of children and young adults more microanatomic dissections in adult cadavers of both sexes, fixed in 10% formalin.

Traumatic acute brain herniation through the ear in a child: concealed compound fracture

A seven-year-old girl presented to Sultan Qaboos University Hospital, Oman, with a history of having been hit by a motor vehicle. After this, she had right-sided cerebrospinal fluid otorrhoea, and a week later, brain matter extruded through the right ear. A computed tomography scan of the brain demonstrated a tegmen fracture communicating with the external auditory canal. There was no hearing or facial nerve impairment and an otoscopic examination showed an intact tympanic membrane. She underwent a transcranial repair of the middle cranial fossa base, which revealed a wide dural and bony defect of the tegmen with herniation of the temporal lobe. Repair was made with an intradural patch of artificial dura. The rarity of this type of presentation of temporal bone fracture and its management are discussed

Fracture of the temporal bone: A tomographic v/s autopsy study.

The present study was conducted in the Dep’t. of Forensic Medicine & Toxicology, SMS Medical College Jaipur (Raj), in the period from 15 Dec. 2001 to 4 April 2002. With the aim to find out the correlation of X-ray (Skull), CT scan (Head), Surgical intervention findings with the autopsy findings in the cases of acute Head trauma. Total of 140 cases of acute head trauma were selected irrespective of age, sex, religion caste etc. who had been admitted in Neurosurgery dep’t. And X-ray, CT scan head and /or surgical intervention had been done, subsequently died & autopsy was performed. X- ray skull gave batter information on fracture of skull than CT Scan, particularly when the fracture is located on the vault or base of skull and is of linear variety [1]. 27 cases of fracture of the temporal bone were specially studied, out of these 140 cases. All these cases had the features of triad, indicating of fracture of petrous part of temporal bone i.e. CSF Otorrhoea 14(51.1%), 7th nerve palsy 9(33.3%), serve middle ear bleeding 18(66.6%) & conducting hearing loss 5(85%). The plain X-ray demonstrated the fracture of temporal bone in 21 cases (79%) and the CT Scan demonstrated their in 24 cases (88%) Longitudinal fractures are common in 18 cases (66%) and procedure of choice for their demonstration is lateral tomography, Transverse fracture alone was uncommon (2 cases) and can only be demonstrated in anterior posterior tomographic projections and is usually associated with occipital fractures. CT Scan Examination give better information in detection of fracture of temporal bone as well as the type of fracture [2] which is essential for planning the surgical intervention or treating the patient conservatively in order to avoid the complications like, persistent CSF otorrhoea, posterior meningitis or even death.

Hipoacusia como secuela de fractura de hueso temporal: servicio de foniatría del Hospital "Dr. Agust¡n Zubillaga" octubre 2001 julio 2002 / Hearing loss with secuela of temporal bone fracture: service of phoniatric

Para observar el fenómeno de hipoacusia como consecuencia de fractura de hueso temporal, se realizó un estudio descriptivo, en el Servicio de Foniatría del Hospital "Dr. Agustín Zubillaga", en Barquisimeto, Venezuela, con una muestra de 21 pacientes de ambos sexos, entre 09 y 64 años de edad, quienes fueron referidos por presentar fractura de hueso temporal. A cada paciente se le determinó el tipo de fractura temporal, a través de la tomografía axial computarizada de cráneo y oído y posteriormente se les realizó la prueba de audiometría tonal, para valorar la pérdida. Los resultados mostraron que la hipoacusia más comunes comúnmente encontrada fue de tipo superficial y se obtuvo predominio de hipoacusia conductiva para uno de los oídos, y en el otro oído predominó la hipoacusia neurosensorial. La hipoacusia se encontró ipsilateralmente a la fractura de hueso temporal en un 14.3%, contralateralmente 19% y en ambos oídos 66.7%. El tipo de fractura de hueso temporal observada con mayor frecuencia fue de tipo longitudinal (90.4%) y el sexo más afectado fue el masculino.

Traumatismos del hueso temporal / Temporary bone traumatisms

Injuries to the temporal bone are caused by high energy mechanisms. Fractures, longitudinal or transverse, are the most frequent lesions and they need to be specifically searched. If the fracture is not visible, its presence is suspected by means of indirect signs, such as soft tissue occupation within mastoid cells, or in the tympanic cavity, and air in an abnormal situation. The ossicular chain can undergo luxations, being the most frequent the incudomallear joint, and fractures. For the study of traumatic injuries of the temporal bone, the CT scan should be the method of choice, especially by means of multislice technology, since the speed of acquisition, and the good quality of multiplanar reconstructions, facilitates the diagnosis.

: Los traumatismos del hueso temporal ocurren por mecanismos de alta energía. Las fracturas, longitudinales o transversales, son las lesiones más frecuentes y deben buscarse dirigidamente. Si el rasgo de fractura no es visualizado, signos indirectos como ocupación de partes blandas en celdillas mastoideas o en la caja timpánica y aire en lugares no habituales, deberían aumentar la sospecha. La cadena de huesecillos puede lesionarse por luxaciones, la incudomaleolar es la más frecuente, o por fracturas. Para el estudio de las lesiones traumáticas del hueso temporal, la tomografía computada debe ser el método de elección, sobretodo si se realiza con tecnología multicorte ya que, la rapidez en la adquisición y la gran calidad en reconstrucciones multiplanares facilita el diagnóstico.

role of computerized tomography in diagnosis of petrous temporal bone lesions

There are various imaging modalities for the lesions of temporal bone, of which computerized tomography stands out as one of the most reliable modalities, The aim of the study is to evaluate the role of computerized tomography of temporal bone in diagnosis of this region. The material comprises 42 patients with age ranging from 2 to 10 years. We used a Siemens Somaton 4 Plus at El-Hussein and G.E. Systec Plus at Sayed Galal University hospitals. The cases are categorized into: Congenital [8 cases], traumatic [10 cases], inflammatory [14 cases], neoplastic [4 cases]. The main value of C.T. in inflammatory lesions, of temporal bone is its ability to show bony erosions or sclerosis associated with these conditions and the spread of inflammation to adjacent structures. An accurate C.T. examination of temporal bone gives the otorhinolaryngology surgeon a detailed preoperative map that avoid ricky situations

Angiomatose cística do osso temporal: relato de caso / Cystic angiomatosis of temporal bone: case report

Os autores apresentam o caso de uma criança com angiomatose cística do osso temporal, um tipo de hemangioma raro, comentando achados para o diagnóstico e seu tratamento.

Achados otoneurológicos em um caso de fratura do osso temporal / Otoneurologic findings in temporal bone fracture

Fratura de osso temporal é um achado freqüente em traumatismos cranianos. A linha de fratura pode ser paralela ou perpendicular ao maior eixo da pirâmide petrosa, caracterizando assim dois tipos de fraturas: longitudinal e transversal. Distúrbios cocleares e da funçao vestibular sao as complicaçoes tardias mais freqüentemente encontradas nos traumatismos caranianos. O objetivo deste trabalho é descrever resultados das avaliaçoes audiológica e vestibular de um paciente de 55 anos de idade, vítima de traumatismo crânio-encefálico pós-acidente automobilístico com fratura de osso temporal.

Fratura com afundamento craniano em crianças com menos de dois anos de idade / Depressed skull fractures in children under 2 years of age

As fraturas com afundamento da calota craniana (FAC) säo relativamente frequentes e seu tratamento neurocirúrgico está bem estabelecido, porém pouca atençäo tem sido dada a esta patologia na faixa etária de 0 a 2 anos de idade. Este estudo baseia-se na análise retrospectiva de 43 pacientes com FAC e idade entre 0 e 2 anos. As principais causas da FAC foram as quedas, seguidas pelos atropelamentos. A maioria apresentava FAC tipo I, isto é, aquela na qual o osso deprimido permanece conectado à calota craniana. Tratamento cirúrgico foi instituído em 69,8 por cento dos casos. A incidência de lesöes encefálicas associadas foi mais baixa do que a relatada na literatura

Fracturas del hueso temporal / Temporal bone fractures

Los autores realizan una revisión de los casos de fractura del temporal, vistos en su servicio, entre los años 1987 y 1991, incentivados por un aumento de los casos vistos en los últimos años. Se analizan 42 casos que tenían la información adecuada en sus fichas. La gran mayoría adultos jóvenes, de sexo masculino. La principal causa de las fracturas fueron los accidentes y las agresiones. Se realiza también un comentario, con respecto al estudio imagenológico de los pacientes, dado el hecho que no todos ellos contaban con una tomografía computada. El principal signo indicador de fractura encontrado fue la otorragia y el hemotímpano. La gran mayoría de las fracturas eran de tipo longitudinal, siendo el daño auditivo, específicamente la hipoacusia de conducción, la complicación más frecuente (55 por ciento). El número de lesiones al nervio facial (17 por ciento), aunque de menor incidencia, eran porcentualmente mas graves. Finalmente, se propone una forma de diagnóstico y manejo de esta patología
