Patterns of Mandibular Fractures and Associated Comorbidities in Peshawar, Khyber Pakhtunkhwa

Abstract

Objectives The objective of this study was to assess patterns of mandibular fractures and associated comorbidities in Peshawar, Pakistan. Methodology This multicenter, descriptive, cross-sectional study analyzed patients aged >15 years who had been clinically or radiographically diagnosed with mandibular fractures from January to December, 2015. Patients with pathological fractures or bomb-blast injuries were excluded. Data were analyzed using IBM SPSS Statistics for Windows, Version 20.0 (IBM Corp., Armonk, NY). Results The 138 patients diagnosed with mandibular fractures in 2015 included 108 men (78.3%) and 30 women (21.7%), with a male preponderance of 3.6:1. Most patients (56%) were aged 15-25 years, followed by those aged 26-35 years (26%). The most frequent cause of fractures was road traffic accidents (RTAs; 59.42%), followed by falls (18.8%). RTAs were predominant in men (89%); whereas, falls were predominant in women (80%). Fractures due to firearm injuries and interpersonal violence were more frequent in men (p <0.001). In patients with unilateral fractures, the most common fracture site was the parasymphysis (24.6%) followed by the symphysis (10.1%). In patients with bilateral fractures, the most common fracture sites were the parasymphysis and condyle (11.6%), followed by the parasymphysis and angle (8.0%). Conclusions RTA was the most frequent cause of mandibular fracture and trauma. Mandibular fractures were more common in men than women, with most patients aged 15-25 years. The most common fracture site was the parasymphysis.
