Background: The term "orbital blow-out fracture" is referred to as the mechanism by which an impact to the eyeball is transposed as a mechanical energy to the orbital walls, causing them to fracture. Despite a proper surgical technique, a successful anatomic reconstruction of the orbit, and an accurate follow-up, 3 complications are still frequently observed at long-term follow-up: diplopia, enophthalmos, and hypesthesia of the infraorbital nerve territory. In this retrospective study, we analyze the incidence, the specific characterization, and the potential risk factors of these 3 complications. Methods: The records of 75 patients who underwent surgical repair of isolated orbital blow-out fracture from January 2001 to December 2007 at the Maxillofacial Surgery Unit of the Novara Major Hospital were reviewed retrospectively. Patients who had other coexisting facial fractures or orbital rim involvement were excluded from this study. The mean follow-up reached 39 months (range, 6-81 months). Enophthalmos was measured by a Hertel exophthalmometer; diplopia was evaluated by an optometrist with cover test, red glass test, and Hess-Lancaster test; and hypesthesia of the infraorbital nerve territory was checked by clinical examination. The studied parameters included patient's age and sex, time interval between trauma and surgery, location of the fracture, and implant material. The χ² test for nonparametric data was used, and a P value of less than 0.05 was considered statistically significant. Results: Sex, location of the fracture, and implant material were not considered statistically significant (P > 0.05). The unique variable that influenced our data was the time interval between trauma and surgery (P > 0.05). Discussion: Although the surgical technique was executed properly and the immediate postoperative recovery was uneventful, diplopia, enophthalmos, and infraorbital nerve dysfunction were the frequent complications. We stress the fact that orbital blow-out fracture is generally not considered a technically demanding procedure, but the outcome can be very disappointing; the surgical procedure must be managed very carefully by experienced surgeons to lower the high rates of these 3 common complications. However, we can report that the incidence of diplopia, enophthalmos, and infraorbital nerve dysfunction are decreased by an immediate intervention and an early surgical repair of the orbital blow-out fracture. Patients who had surgery within 2 weeks of trauma have a lower risk to develop postoperative complications; this study supports an early surgical treatment of orbital blow-out fractures, when it is indicated.

Background Within the field of facial reconstructive surgery, minimally invasive procedures are used for the treatment of temporomandibular joint disorders, traumas, and salivary glands and base of skull tumors. The recent report of endoscopic approach for treating subcondylar fractures of the mandible is designed to provide a new method for the treatment of subcondylar fractures using an endoscope through a limited transoral incision. To the best of our knowledge, the advantages and the disadvantages of an endoscopically assisted approach to mandibular condylar fracture have not been verified in studies with a high level of evidence. The objective of this article was to present our experience regarding the endoscopically assisted reduction of subcondylar mandibular fractures with a special focus on complications. Methods The records of 14 patients who underwent surgical repair of subcondylar fractures by transoral endoscopic-assisted technique from January 2005 to December 2008 at the Maxillofacial Surgery Unit of Novara Major Hospital were reviewed retrospectively. The measures for the surgical objectives included the following outcome variables: (1) operation time, (2) cosmetic outcome, (3) salivary fistulas, (4) infection, (5) delayed wound healing, (6) facial nerve damage, (7) hemorrhage, (8) repeat interventions, (9) bone consolidation, (10) occlusion changes, and (11) temporomandibular joint dysfunction. Results Our data show that we have had 4 complications (28%) experienced by 4 different patients: (1) arterial hemorrhage, (2) facial nerve injury, (3) nonunion, and (4) partial condylar reabsorption. Conclusions Although we cannot draw statistically significant conclusions, we think that further randomized clinical trials should be necessary to analyze this method; we believe that there is not an ideal approach for a fracture, but each patient needs to be fully evaluated carefully preoperatively, and the more convenient approach needs to be selected for each case.
