A Prospective Randomized Study to Assess the Quality of Life in Post-Operative Recovery Phase in Patients Undergoing Surgery for Isolated Vertically Undisplaced Mandibular Parasymphysis Fracture Using Twin Mix Solution

Trauma is a major cause for facial fractures commonly encountered by maxillofacial surgeons. Mandible is commonly involved in facial trauma resulting in an isolated fracture or associated with other facial bones due to its prominent location in the facial skeleton. This study was undertaken to investigate the quality of life (QoL) post-operatively in patients diagnosed with undisplaced parasymphysis fracture who underwent open reduction and internal fixation (ORIF) under local anesthesia (LA) using the twin mix (TM) solution. A prospective randomized clinical study was conducted among 40 patients aged between 20–55 years requiring ORIF for unilateral vertically undisplaced parasymphysis fracture under LA. Group A patients (n = 20) received conventional LA solution with adrenaline, and Group B patients (n = 20) received freshly prepared TM solution for their surgical intervention as a day care procedure. Various parameters such as jaw function, ability to masticate and labialis activity (lower lip pout) were assessed. The data were collected and analyzed applying student’s t test, Shapiro–Wilk test using SPSS software. All the 20 patients in Group B who received TM solution exhibited better jaw function and mouth opening with a mean score of (±SD) of 4.55 (±0.944). They also exhibited reduced difficulty in mastication and ability to purse the lower lip on third post-operative day as compared to the patients in Group A. No complications were observed among the patients post-operatively in both the groups of this study. TM solution proves to be superior as compared to the conventional LA solution as the former offers an improved clinical outcomes enhancing the QoL post-operatively in patients undergoing ORIF for undisplaced parasymphysis mandibular fracture.
