Abstract
INTRODUCTION: This study reports on a modified approach to treat zygomatic fracture. For the surgical approach, a transconjunctival incision and, instead of a lateral canthotomy, a superficial incision of the skin and subcutaneous tissue was used, preserving the lateral ligament. The results are compared with those of previous techniques, especially the subciliary incision. PATIENTS: In a prospective study, 30 patients (9 females and 21 males, mean age 32.1 years) with zygomatic fractures were operated using this approach. Mean follow-up time was 6 months after removal of the plates. Fractures were caused by trauma due to fighting, bicycle falls, or sport accidents. Follow-up radiographs were used to evaluate the position of the zygoma after reduction and rigid fixation. RESULTS: Reduction and rigid fixation of the fractures were possible to perform in all cases. The access to the orbital floor and the exposure of the inferior and lateral rim were satisfactory and an additional latero-orbital cut was not necessary. The disadvantage of the complete incision of the lateral ligament with the necessity of intraoperative refixation and possible ectropium of the eyelid could be avoided. Injuries or infections of the cornea or the bulbus did not occur. Postoperative complications such as scar formation resulting in entropium or ectropium were not seen. CONCLUSION: These results show that the transconjunctival approach with lateral superficial incision preserving the lateral ligament for treatment of zygomatic fractures is satisfactory in all cases of rigid fixation of both inferior and lateral rims. Because of its esthetic and functional advantages this approach has become standard in our department.
