Also, the most common postoperative complication was hypoesthesia in 34.2%. 7 Rosado and de Vicente 8 reported that the most frequent sequelae of 314 patients with orbital fractures were hypoesthesia in 24.5% of patients. The etiology of traumatic sensory dysfunction of the trigeminal nerve branches is presumed as nerve compression due to dislocated bone fragments, nerve traction from a displaced fracture, transection of the nerve, nerve manipulation by the fracture reduction, and bony proliferation along a healing fracture site. 10 Hypoesthesia itself is not a major disability. However, persistent hyperesthesia can be dis- abling. 6 Although post-traumatic hypoesthesia of the infraorbital nerve is common, persistent hyperesthesia is rare. 4,5 Bailey et al 4 described chronic infraorbital hyperesthesia by compression in the infraorbital canal. Soft tissue adhesion and bony impingement to the infraorbital nerve were the causes of the hyperesthesia. Our patients had developed a very specific complaint of pro- gressive hyperesthesia in surgically repaired orbital fracture patients. In patient 1, the scar tissue formation and bony proliferation are responsible for persistent hyperesthesia after fracture reduction. Boyne reported, in monkeys, that disruption of the inferior alveolar canal following tooth extraction leads to bony proliferation during the healing process, which subsequently causes narrowing of the diameter of the canal and damage to the inferior alveolar nerve. 11 Hence, in patient 1, a similar condition of impaired inferior orbital sulcus by the fracture was possible. 1 Tiny irregular shaped bones at the fracture site are likely to leads to bony proliferation during healing process and it could compress the infraorbital nerve. When inserting the alloplastic implant, the surgeon need to get clean up the tiny bone pieces surrounding the infraorbital nerve. It could prevent the nerve from being compressed by the scar tissue and bony proliferation. Recently, resorbable alloplastic implants have been used in the reconstruction of orbital fracture. The dense fibrous capsule encapsulated alloplastic implant. 12 In patient 2, fibrotic band-like scar tissue spread through the holes of the mesh that could be happen an adhesion in the infraorbital nerve. It could cause the infraorbital nerve to be compressed leading to hyperesthesia. Fibrotic bands between the infraorbital nerve and alloplastic implant could cause progressive hyperesthesia. We recommend that the infraorbital nerve needs to be separated enough from the alloplastic implant through a careful sharp dissection. Although complete improvement of infraorbital nerve dysfunc- tion associated with fractures is expected following surgical repair, hyperesthesia leads to a serious life-time problem, as in our patients. These were rare cases of patients who presented with hyperesthesia after reduction of orbital fracture. Clinician should perform early surgical decompression of the infraorbital nerve in patient with persistent hyperesthesia. REFERENCES 1. Bagheri SC, Meyer RA, Khan HA, et al.

Orf lesions are typically seen on the hand, but they have rarely been reported on the nose. Herein, the authors report a rare patient of an orf lesion on the nose of a 52-year-old man after the Muslim celebration of the feast of the sacrifice. The lesion spontaneously recovered 8 weeks after the initial appearance and showed no evidence of recurrence after 1 year of follow-up. Orf virus FIGURE 2.

The small bony spur (black arrow) was noted compressing the infraorbital nerve around its sulcus. (B) The infraorbital nerve around the infraorbital foramen of the maxillary bone was normal in appearance (black arrow). (C) The band-like dense fibrous tissue around the implant expanded through the hole of implant toward the infraorbital nerve (black arrow).
