Lower Eyelid Complications in Facial Fracture Surgery.

BACKGROUND: Facial fractures may lead to sequelae due to the trauma but also as a result of surgery. Complications to lower eyelid incisions include ectropion, scleral show, entropion, canthal malposition, and lid edema. The aim of this study was to compare the occurrence of such complications depending on whether a subciliary or transconjunctival incision was used for surgical access. METHODS: All consecutive patients surgically treated for a facial fracture between June 2005 and December 2012 with a lower eyelid incision and a minimal follow-up of 6 months were included in this retrospective study. Patients were grouped according to type of lower eyelid incision (transconjunctival vs subciliary). RESULTS: Out of 128 patients, 37 (29%) had a subciliary and 91 (71%) had a transconjunctival incision. In the subciliary incision group, 3 patients (8.1%) had ectropion and 4 patients (11%) had scleral show whereas 2 patients (2.2%) had ectropion, 4 patients (4.4%) had scleral show, and 2 patients (2.2%) displayed canthal malposition in the transconjunctival incision group. The differences between the groups were not statistically significant. No patient had an entropion. CONCLUSIONS: Subciliary incisions had a higher incidence of ectropion and scleral show compared with transconjunctival incisions. Transconjunctival incisions did show a low risk of canthal malposition needing surgical correction; however, the actual numbers were low. Based on this and earlier studies, the authors routinely perform transconjunctival incisions, without a lateral canthotomy if possible, for surgery of facial fractures.

Long-term sensory disturbances after orbitozygomatic fractures.

BACKGROUND: Orbitozygomatic fractures often lead to infraorbital nerve (ION) injury, and affected sensibility is a common long-term complaint within this patient group. We present a long-term follow-up study where the validated von Frey filament system was used for testing ION sensibility. Furthermore, we examined the incidence of persistent nerve injury and whether more complex fractures led to more pronounced ION sensibility disturbances. METHODS: Patients treated for facial fractures involving the orbitozygomatic complex were included and the follow-up time was 3 years or more. Depending on the location and severity of the fractures, the patients were divided into 4 groups. The patients answered a questionnaire before ION sensibility testing with von Frey filaments. RESULTS: Eighty-one patients were examined: 65 males (80%) and 16 females (20%). Examinations were conducted between 3.0 and 7.6 years (mean 4.9 years) after injury. Sixteen patients (20%) had affected and 6 patients (7.4%) had severely affected ION sensibility according to von Frey testing. No statistically significant differences were found in terms of questionnaire score between the groups. There was also no statistically significant correlation between questionnaire results and log von Frey values. Although the effect of groups could not be statistically verified using the log von Frey values, a larger proportion of patients with complex fractures had higher log von Frey values than the other groups. CONCLUSIONS: Patients with complex fractures report more permanent sensory disturbance of the ION after surgery than those with isolated orbitozygomatic fractures, although this could not be verified statistically with von Frey filament testing at several locations. Hence, a validated method for testing facial sensibility such as von Frey filaments, although sensitive, is inadequate to determine all aspects of sensory malfunction after orbitozygomatic fractures. This suggests that the patient's experience of long-term sensation after trauma may not be correlated with objective measures.
