Short-Term Outcomes of High-Density Porous Polyethylene Orthoses for Chin and Gonial Angle Augmentation.

Abstract

This retrospective observational study evaluated 100 patients over 18years. Data on age, sex, aesthetic complaints, surgery types, and postoperative complications were collected and analyzed using the two-proportion z-test and descriptive statistics in RStudio 4.3.3. All patients with neuropraxia underwent neurosensory evaluation. The average age was 35.92years for males and 33.71years for females, with a male predominance (76%). Aesthetic complaints were prevalent in 72% of patients (p < 0.01). Chin surgery was performed on 56% of patients, jaw angle surgery on 17%, and both on 39%. Complications included one case of suture dehiscence, three wound infections, and four transient cases of paresthesia, all resolving within 30days. Overall, patient satisfaction with outcomes was high. High-density porous polyethylene implants proved effective and safe in enhancing facial aesthetics and correcting mandibular deformities. Further research should focus on long-term outcomes to consolidate these findings. This journal requires that authors assign a level of evidence to each article.
