Objective assessment of progressive increase in bite force post surgical correction of mandibular fractures using Nupai bite scan analyser

Background: Fracture of mandible is a common condition which is increasing in incidence in the trauma centers due to increasing motor vehicles and failure to abide by traffic regulations. Patients undergo surgical open reduction and internal fixation where post-operative occlusion and normal masticatory functions are targeted. Bite force can be taken as a guide of normal masticatory function of an individual which is dependent upon craniomandibular biomechanics. The aim of the study was to analyse bite force measurements post-operatively in patients who underwent open reduction and internal fixation for mandible fractures at different sites.Methods: Molar bite force was recorded in 31 post-operative patients who underwent open surgical procedure for fracture mandible in the department of plastic surgery from January 2018 to June 2019 by a pre-scale bite force recorder-Nupai bite force prescale system (FujiTM). Various parameters were recorded pre and post-operatively including age, gender, history, comorbidities, requirement of MMF, site and number of fractures and age of injury. Bite force were compared and improvement of bite force every 2 weeks was noted and analyzed upto 6 weeks postoperatively.Results: Bite force improvement was seen in all types of mandible fractures irrespective of the site and type of fractures over a period of 6 weeks post-operatively. This improvement was however not statistically significant. Decreased time interval form injury to surgery resulted in improved bite force measurements though not statistically significant.Conclusions: Although objective improvement in bite force could be demonstrated but extensive study involving more subjects and more patient variables would have statistical significance.

Mandibular fractures are a common injury encountered by facial trauma surgeons. A majority of these cases are in dentate patients and can predictably be treated with several different open or closed techniques. Edentulous mandible fractures can be challenging as maxillomandibular fixation, either as the sole treatment or used for fracture reduction and stabilization prior to internal fixation, is not possible. The atrophic edentulous mandible fracture poses an even greater challenge, as there is more sclerotic bone present and less bone volume for bony contact, both of which can impair healing. In addition, with less bone mass, available plate adaptation and fixation are difficult. In recent years, virtual surgical planning (VSP) has been increasingly used in craniofacial and maxillofacial surgeries as well as in dentistry. Utilizing VSP to fabricate the necessary hardware prior to open reduction and internal fixation of atrophic edentulous mandible fractures can be helpful in treating these cases. Two cases where this method was used are presented.

Head And Neck Injury

Background: A great deal of work has been directed toward using these symptoms to classify the severity of head injury. Loss of consciousness or coma and posttraumatic amnesia (difficulty in remembering new information after waking up from the coma) are the two most common symptoms used. A mild head injury is one in which the period of unconsciousness is less than twenty minutes and post traumatic amnesia lasts for less than one hour, while a head injury in which the person is unconscious for at least one day and experiences post traumatic amnesia for more than twenty four hours is considered severe. Methods: 50 Cases coming to O.P.D and casualty of Chigateri general hospital and Bapuji hospital attached to JJM Medical College, Davangere were studied. Results: Evidence of C.S.F rhinorrhoea was noticed in 1(2%) case which managed conservatively. Maxillary fracture was noticed in 05 (10%) cases which were managed conservatively. Zygomatic fractures were noticed in 07 (14%) cases which were managed by open reduction and internal fixation with mini plates under general anesthesia. Conclusions: Mandibular fractures were noticed in 10 (20%) of cases which were managed by open reduction and internal fixation with mini plates under general anesthesia.
