RESUMEN
Orbital fractures are a common sequela of maxillofacial zone trauma. Rapid assessment and management are essential for successful reconstruction. The selected treatment method depends on fracture types, accompanied injuries, and intervention time. Implantable grafts used to be from autologous materials. The study aimed to evaluate the effectiveness of using the auricular conchal cartilage taken from the ear to repair orbital floor fractures in cases of minimal bone loss, less than (2×2) cm. Material and Methods: A prospective single-arm, nonrandomised clinical trial was conducted during the past 4 years (from 2018 to 2022). A total of 15 cases, who had visited the department of oral and maxillofacial surgery department with orbital floor fractures, were enrolled. The participants underwent conchal cartilage grafting for orbital floor fracture reconstruction. The time factor to perform the surgery after trauma had been considered. Patients were closely monitored for the development of double vision (diplopia) at 15 days, 1 month, and 3 months postsurgery. Results: The results showed statistically significant differences during the follow-up period following the surgical procedure. They appeared to have complete restoration of eye movements, restoration of the normal positioning of the eyeball affected by the orbital floor fracture compared to the healthy eyeball, and regression of double vision (diplopia) throughout the follow-up period. Conclusion: Using the auricular conchal cartilage graft in repairing fractures of the orbital floor resulted in the improvement of the functional aspect of the eyeball and the restoration of the esthetic aspect.
