Lower lip paresthesia prevalence due to mandibular fracture in patients of Imam Reza educational and medical center, Tabriz, in 1401

Abstract

Fracture of the lower jaw in the face, if not diagnosed or treated properly, may lead to severe complications in the aesthetic, functional, and psychological aspects of patients. In the present study, we examined the prevalence of lower lip paresthesia in relation to various types of mandibular fractures in patients referred to the Imam Reza Educational Hospital in Tabriz in 1401. Materials and Methods: This retrospective cross-sectional study was conducted on the medical records of trauma patients at Imam Reza Hospital in 1401. All records meeting the study criteria were reviewed. Initially, a comprehensive list of patients was prepared using the Hospital Information System (HIS), and archived files were extracted. Necessary information was collected through medical history, clinical examinations, facial radiographs, and hospital records. Data including age, gender, cause of injury, fracture location, fracture type, and presence or absence of paresthesia were recorded. Types of mandibular fractures were categorized based on anatomical location (condyle, ramus, angle, body, symphysis, parasymphyseal, and coronoid). The prevalence of lip paresthesia was analyzed using SPSS Ver. 25 software, and the frequency and percentage of lip paresthesia and comparison of lip paresthesia based on fracture location were examined using Fisher's exact test. Results: The prevalence of lower lip paresthesia in patients with mandibular fractures was 55.4% (37.7% on the right side and 32.3% on the left side). The prevalence of lower lip paresthesia was 52.1% in men and 64.7% in women. The highest prevalence of lower lip paresthesia was observed in fractures involving the body region (33.57%). The prevalence of paresthesia in fractures involving the condyle and subcondylar regions (24.48%), angle (19.58%), symphysis and parasymphyseal regions (19.58%), coronoid (1.40%), and ramus (1.40%) were in the next categories of this comparison. Conclusion: The prevalence of lower lip paresthesia in patients with mandibular fractures was 55.4%.
