Evaluation of demographic, radiological and intraoperative factors for assessment of postoperative pain and complications in surgical removal of impacted mandibular third molar: a prospective study / Evaluación de factores demográficos, radiológicos e intraoperatorios para la evaluación del dolor postoperatorio y las complicaciones en la extracción quirúrgica del tercer molar mandibular impactado: un estudio prospectivo

Third molars usually erupt within the age of 17 ­ 21years. Usually, due to the evolution of human jaws, the size is decreasing leading to the impacted tooth. An impacted tooth may lead to external resorption of the adjacent tooth, trismus, infection, etc. Many studies have been reported in the literature for evaluating the surgical difficulty and postoperative complications secondary to impacted third molars. This study includes a sample of 100 subjects evaluated for the surgical difficulty and postoperative complications. Various demographic, radiological, and intraoperative factors were evaluated which may lead to postoperative complications. Factors responsible for postoperative sequelae were also evaluated with complications. Postoperative pain after 4 hours and 7 days was assessed to mark the factors commonly responsible. Pain at 7th postoperative day was significant involving factors like fully impacted, horizontal impaction, level C, no/very little retromolar space, and root contact. Postoperative complications were not reported in this study.

Los terceros molares suelen erupcionar entre los 17 y los 21 años de edad. Por lo general, debido a la evolución de las mandíbulas humanas, el tamaño disminuye, lo que conduce al diente impactado. Un diente impactado puede conducir a la reabsorción externa del diente adyacente, trismo, infección, etc. Se han reportado muchos estudios en la literatura para evaluar la dificultad quirúrgica y las complicaciones postoperatorias secundarias a terceros molares impactados. Este estudio incluye una muestra de 100 sujetos evaluados por la dificultad quirúrgica y las complicaciones postoperatorias. Se evaluaron diversos factores demográficos, radiológicos e intraoperatorios que pueden conducir a complicaciones postoperatorias. También se evaluaron los factores responsables de las secuelas postoperatorias con las complicaciones. Se evaluó el dolor postoperatorio después de 4 horas y 7 días para marcar los factores comúnmente responsables. El dolor al séptimo día postoperatorio fue significativo e involucró factores como impacto total, impactación horizontal, nivel C, espacio retromolar nulo o muy pequeño y contacto con la raíz. En este estudio no se informaron complicaciones posoperatorias.

CRB modification to retromandibular approach for management of subcondylar fractures

The aim of this study was to evaluate the efficacy of CRB modification of retromandibular approach to gain surgical access for open reduction and internal fixation of mandibular sub-condylar fractures. A total number of 264 sustained extra-capsular subcondylar fractures from 230 patients were selected for the study over the period of 5 years. Evaluation of intraoperative accessibility, postoperative facial nerve function, postoperative complications and scar was ca-rried out. All the patients were treated using CRB Curvilinear approach. Patient follow up was re-corded for 1 year on a regular interval basis. Symptoms of postoperative facial nerve injury were seen in 2 patients which recovered with time, postoperative complications were not encountered in any case and minimum scar mark hidden in the cervical skin crease. Hence open reduction and internal fixation for Subcondylar fracture of mandible by using the CRB modification of re-tromandibular approach is a good alternative for other conventional approaches in having ease of access, ease of fixation, reduced incidences of injury to facial nerve and its branches with good aesthetic outcome

Assessment of intraoperative risk factors for surgical difficulty in surgical extraction of impacted mandibular third molar: a prospective study

The extraction of impacted third molars is among the most common surgical procedures carried out in the field of Oral and Maxillofacial Surgery. For proper planning of surgical extraction, espe-cially for impacted mandibular third molars the estimated level of surgical difficulty of the case is important. This study was conducted to evaluate the intraoperative risk factors contributing to surgical difficulty in extraction of impacted mandibular third molars and consequently the post-operative outcome. Here, we have undertaken a study in which the intraoperative variables were considered, to evaluate their contribution for surgical difficulty and postoperative complica-tions in surgical removal of 100 impacted mandibular third molars. Three variables were found significant associated with total surgical time intervention, i.e., surgeon's experience (p=0.006), Inter-incisal opening (p=0.032), and cheek flexibility (p=0.004). Total surgical time intervention for 'right side' was higher with 49.20 ± 17.94 minutes (p=0.691). Total surgical time intervention for 'gagging reflex present' was 50.21 ± 17.812 (p=0.674). Multiple linear regression shows that surgeon's experience was the only predictor (p<0.001). The surgical difficulty of impacted mandibular third molar are likely to depend on the intraoperative factors like Surgeon's time, surgeon's experience, check flexibility, and inter incisal mouth opening.
