Assessment of Infraorbital Nerve Parasthesia after ZMC Fracture and Its Surgical Repair
Department of Oral and Maxillofacial Surgery – Faculty of Dental Medicine, Al-Azhar University, Cairo
Abstract
Background: Infraorbital nerve parasthesia is a very common finding after maxillofacial trauma involving zygomaticomaxillary complex (ZMC) region. The use of computer assisted surgical protocols for managing these fractures could improve the surgical outcome and maximize the functional and esthetic reconstruction of traumatized bones with possible effect on infraorbital nerve recovery. Objective: The aim of the present study was to assess infraorbital nerve parasthesia after ZMC fracture and its surgical repair. Patients and Methods: A total of 10 patients with unilateral ZMC fractures were selected from those having maxillofacial injuries at the Emergency Room of Sayed Galal University Hospital, Al-Azhar University, Cairo. Patients were divided randomly into two groups (five patients each); Group I: patients were treated with mirror imaging technique and fabrication of a steriolithographic (STL) model. Group II: patients were treated through the traditional technique without fabrication of an STL model. Results: Infraorbital nerve affection occurred in 7 patients (70%), 4 in group I and 3 in group II. Recovery of the nerve occurred at 3 months postoperatively except for only one patient from group II. Statistically, no significant difference was found between both groups. Conclusion: Although computer assisted surgery is impressive and has a remarkable role in facilitating the precise contouring and adaptation of the titanium plates / mesh needed for fracture repair, it has no evident advantages over the traditional techniques regarding infraorbital nerve recovery.
