“…This can complicate the splitting of the mandible and give rise to a bad split. 3 Some modifications were made to the medial osteotomy to reduce the risk of a bad split in the lingual Plate. [4][5][6] It has been shown that the length of the medial osteotomy is an important factor in reaching a desirable result, 11 and it has been suggested that a short osteotomy line is an appropriate method.…”

“…2 Since its introduction, many modifications of the original technique have been described in an attempt to decrease the risk of bad splits, to avoid non-union, and to prevent trauma to the inferior alveolar nerve. 3 Originally, two osteotomy models were suggested for the lingual side of the ramus in SSO, namely a long osteotomy line that extends beyond the lingula and finishes at the posterior border or near it, and a short osteotomy line that ends approximately at the lingula. [4][5][6] The identification of the various patterns of medial fracture may be important to prevent bad splits and nerve injuries.…”

“…Las referencias anatómicas y las estructuras de riesgo deben ser tomadas en cuenta sobre todo en las recientes modificaciones de la técnica quirúrgica Obwegeser-Dal Pont, donde se debe realizar una osteotomía adicional en el borde inferior de la mandíbula (Böckmann et al, 2011;Schoen et al, 2011).…”

RESUMEN: La osteotomía sagital de la rama mandibular (SSRO) es una de las técnicas quirúrgicas más frecuentes para corregir las deformidades de la mandíbula. Con el fin de prevenir problemas anatómicos y quirúrgicos, los cirujanos requieren una mayor investigación sobre las estructuras anatómicas relacionadas con la SSRO. El objetivo de este estudio fue investigar las posiciones de la antilingula (AL), la entrada al nervio alveolar inferior (NAI) en la mandíbula y otros puntos de referencia anatómicos en relación con la língula mandibular (L). Fueron estudiadas 70 hemimandíbulas secas. La AL y los demás puntos de referencia y, la posición correspondiente de la L se marcaron en la cara medial y lateral de la rama mandibular respectivamente. Fueron medidas las distancias de la AL, NAI y L en los planos anterior-posterior y superior-inferior con un caliper, y se estableció su relación geométrica. Los resultados mostraron que la AL era perceptible en el 100% de las caras laterales mandibulares. La mayoría de las ALs se encuentran anterior a la L, con una distancia media de 0,66±2,43mm y 0,92±2,56 mm y, 4,23±2,97 mm y 3,62 ± 3,14 mm superior a ella (lados derecho-izquierdo respectivamente) (ambos con un valor de p <0,001). Valores similares se observaron en relación con el NAI. No se encontraron diferencias significativas entre los lados derecho e izquierdo, para la mayoría de los parámetros. Los parámetros estudiados pueden asistir a los cirujanos maxilofaciales a determinar la proximidad anatómica del NAI, y reducir al mínimo el riesgo de dañar el nervio y vasos sanguíneos. No recomendamos el uso de la AL como única referencia anatómica cuando se realiza un procedimiento de SSRO.PALABRAS CLAVE: Osteotomía sagital de la rama; Mandíbula, Puntos de referencia anatómicos; Antilingula; língula; Nervio alveolar inferior.

Objective: This preliminary study was planned to provide information about preoperative mandibular canal (MC) position and the postoperative positional changes of MC and length in three dimensions, with the purpose of providing some assistance in reducing inferior alveolar neurosensory disturbance (IAND).Methods: MC was examined on CBCT data using SimPlant Pro Standalone 13.0. MC locations were measured in all dimensions, with respect to mandibular bony borders. Results:The results showed that MC is frequently located in the midthird of the ramus anteroposteriorly and superoinferiorly and in the midthird of the corpus superoinferiorly. Postoperatively, ramus width was increased, ramus length was decreased significantly, and MC was repositioned laterally and inferiorly. MC length was decreased on both sides, non-correlated with the set-back amounts. Conclusion:Preoperative results may be beneficial for the prediction of MC position for surgeons, and postoperative results will be used for the following studies to correlate postoperative positional changes with IAND.
