Treatment outcome of patients with mandibular symphyseal fractures treated with titanium plate and screw fixation

Tóm tắt

Objective: To describe the clinical and radiographic characteristics of patients with mandibular fractures in the chin region treated with titanium plate and screw fixation at Viet Tiep Hospital in 2023. Subjects and Methods: A cross-sectional descriptive study was conducted on patients diagnosed with mandibular fractures in the chin region who visited and underwent surgical treatment with titanium plate and screw fixation at the Department of Oral and Maxillofacial Surgery, Viet Tiep Hospital, from January 2023 to October 2023 due to trauma. Patient records and CT scan films were fully collected. Mandibular fractures were classified based on anatomical location. Results: The study found that 90% of patients with mandibular fractures underwent surgery within a week of trauma, with most requiring two titanium plates for fixation (63.3%). Post-operative recovery was rapid, with 93.3% discharged within a week, and complications such as wound drainage (20%) and tooth extraction (6.7%) were minimal. Jaw fixation was required for 2-3 weeks in 56.7% of cases, while 10% of patients did not need fixation due to non-displaced fractures. Radiographic evaluations showed excellent outcomes in 83.3% of cases before discharge, with no poor results. At six months post-surgery, anatomical recovery was excellent in 96.7% of patients, with 93.3% achieving optimal functional and aesthetic outcomes. These findings highlight the efficacy and reliability of titanium plate fixation for mandibular fractures. Conclusion: Most patients were hospitalized for treatment within one week after surgery (93.3%), with none requiring more than two weeks. The majority underwent surgical fixation using two titanium plates (63.3%). Jaw fixation was predominant, with most patients requiring fixation for 2-3 weeks. One week after surgery, 83.3% of patients had good outcomes, with no poor results reported. At six months post-surgery, the proportion of patients with excellent outcomes increased to 93.3%, with no recorded poor results in terms of anatomical alignment, functionality, or aesthetics.
