ABSTRACT

Objective: To compare the functional recovery of infraorbital nerve paresthesia following open reduction as compared to closed reduction in zygomaticomaxillary complex fracture management.

Study Design: Randomized controlled trial.

Place and Duration of Study: Oral and Maxillofacial Surgery Dept. Dentistry Section, Ayub Medical College & Teaching Hospital, Abbottabad from 1^st April 2016 to 30^th September 2016.

Methodology: Eighty two patients of infraorbital nerve recovery were included. They were divided in two groups; group A was treated by closed reduction technique, and group B was treated by open reduction with internal fixation technique using mini plates. Permuted blocks of 6 were used to ensure equal representation in both groups. All patients were underwent surgical management within 1-7 days following trauma. Patients were assessed post-surgery for infraorbital nerve recovery.

Results: There were 63.4% males and 36.6% females in group A while  60.9% males and 39.1% females were included in group B with mean age was 28.44±7.15 years in group A and 27.93±7.33 in group B respectively. 51.2% patients have infraorbial nerve recovery in group A while 65.8% have infraorbital nerve recovery in group B.

Conclusion: Closed reduction approach was found to be the best reduction technique and open reduction was effective in terms of stability, prevention of relaps and functional recovery of infraorbital nerve injuries.
