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.

Epidemiología y resultado estético funcional de la reducción de la fractura nasal / Epidemiology and aesthetic and functional outcome in nasal bone fracture reduction

Introducción: Las lesiones faciales traumáticas más frecuentes son las fracturas nasales debido a la prominencia de la pirámide nasal. Existe cierto consenso en que cuanto antes se intente su reducción más posibilidades existen de obtener un resultado exitoso. Objetivo: Describir epidemiológicamente y evaluar los resultados funcionales y estéticos de las fracturas. Material y método: Se revisaron las fichas clínicas de los pacientes para describir los datos epidemiológicos, se realizó la encuesta SNOT-22 para evaluar los resultados funcionales y una encuesta cualitativa para la percepción estética de las reducciones. Resultados: De un total de 42 pacientes, predominó el sexo masculino 6:1, la edad promedio fue de 34,4 años. El 83,3 por ciento de la reducciones se realizó en policlínico con anestesia local y el procedimiento se realizó en promedio 8,6 días posfractura. Sobre el resultado funcional destaca la obstrucción nasal posreducción en 43,6 por ciento con un puntaje SNOT-22 promedio de 46,9 puntos y el 47,62 por ciento> consideró su resultado estético como peor. Discusión: Consideramos el resultado estético funcional como no satisfactorio, por lo que no sería inadecuado realizar cirugía de rinoseptoplastía inmediata o diferida para mejorar el resultado.

Introduction: Nasal fractures are the most common facial injuries because ol the prominence of the nose. There is some consensus that the sooner you try their reduction more likely is a successful outcome. Aim: Epidemiologically describe and evaluate functional and aesthetic results of nasal fractures. Material and method: We reviewed the medical records of patients to describe the epidemiológical data, perform the SNOT-22 survey to evaluate the functional results and a qualitative survey for aesthetic perception of the reductions. Results: Of a total of 42 patients, males predominated 6:1, average age was 34.4 years. 83.3 percent of the reductions took place in clinic with local anesthesia and the procedure was performed on average 8.6 days post-fracture. With regard to functional outcome highlights only nasal obstruction after reduction of 43.6 percent with a SNOT-22 scoring average of 46.9 points and 47.62 percent of patients considered a worse cosmetic outcome. Discussion: We believe that the functional and aesthetic result is not satisfactory, so we would recommend a septorhinoplasty immediate or detened for better results.

Application of finite element method in evaluation of craniocerebral trauma / 法医学杂志

FEM combined with modern computer technology is a mathematical method for stress analysis. It has gradually become a significant experimental tool to explore the functions of biomechanically simulated human body structure and mechanism of craniocerebral injuries. This paper reviewed the features and biomechanical materials of the FEM human head models, materials assignment and their applications in blunt injury, fall, traffic accident. It also explore their merits and values in forensic head injury cases.
