A few mucoceles developing secondary to facial bone fractures have been reported. Mucocele formation is thought to be attributable to displacement of the respiratory mucosa with obstruction of the sinus opening, especially if untreated. Accurate diagnosis and management are required; a growing mucocele will gradually destroy adjacent bony structures and cause irreversible complications. The authors describe a patient who presented with diplopia and mild discomfort when gazing upward. She had undergone reconstruction of medial and inferior orbital fractures 20 years previously. The patient was diagnosed with a mucocele developing after orbital fracture repair. The patient underwent mucocele removal and orbital reconstruction using a polyetheretherketone patient-specific implant. In a patient with orbital symptoms but without acute trauma, a mucocele should be among the differential diagnoses if history-taking reveals past orbital trauma and surgery. A polyetheretherketone patient-specific implant was effective for orbital reconstruction after mucocele removal.

Complex dorsal dislocations of the metacarpophalangeal joint are usually a complication of hyperextension injury and are irreducible to closed maneuvers. The volar plate displaced between the dorsum of the metacarpal head and the volar base of the proximal phalanx is the obstacle that prevents reduction. While the pathophysiology of complexity is relatively clear, such injuries are uncommon and reduction requires experience. We describe a case of complex fracture dislocation of the index metacarpophalangeal joint with a review of the literature on relative anatomy and treatment armamentarium.

(1) Background: Orbital wall fractures are common in maxillofacial trauma, and artificial implants are often used for reconstruction. However, there has always been concern about infection because implants are directly exposed to the airway. This study was conducted to determine the effectiveness of a combination of resorbable plates and antibiotic-impregnated collagen sheets in reconstructions of orbital fractures and to determine whether it had an effect in reducing postoperative antibiotic use. (2) Methods: The retrospective study was conducted on 195 patients who underwent orbital wall reconstruction from March 2019 to August 2022. The 176 patients in the control group underwent reconstruction using only resorbable plates and were administered postoperative antibiotics for 5 to 7 days. On the other hand, the 19 patients in the experimental group underwent reconstruction using a combination of resorbable plates and antibiotic-impregnated collagen sheets and only received antibiotics once before surgery. The occurrence of ocular complications, the length of hospitalization, the infection incidence rate, and the adverse effects of antibiotics were investigated. (3) Results: significant ocular complications were observed in the experimental group during a follow-up period of more than 1 year. Regarding postoperative infections, there were two cases of infection in the control group (infection rate: 1.14%), while no infection was found in the experimental group. The hospitalization period of the experimental group was significantly shorter than that of the control group (p < 0.01), and the incidence of total adverse effects of antibiotics, especially nausea, was lower in the experimental group (p = 0.02). (4) Conclusions: The combined use of resorbable plates and antibiotic-impregnated collagen sheets allows effective orbital wall reconstruction without infection, with a shorter hospital stay, and with fewer antibiotic adverse effects.

Accessory extensor pollicis longus tendons are rare tendon anomalies. This report describes the case of a 54-year-old man who presented with pain and difficulty extending his thumb. Upon initial examination, despite a history of trauma, he could extend the interphalangeal joint, but with limited range. During the surgical exploration, an accessory extensor pollicis longus tendon was unexpectedly discovered. This tendon ran parallel to the extensor pollicis longus on the radial side and then attached to the distal phalanx of the thumb. Accessory extensor tendons are more commonly found on the ulnar side than on the radial side of the hand; therefore, this case is notable due to the unusual location of the tendon. After appropriate repair surgery, the patient successfully regained a normal range of motion. While previous classifications of extensor tendon anomalies have focused on the relationship between the extensor indicis proprius and extensor digitorum communis, this case suggests that it is also necessary to consider the relationship with the extensor pollicis brevis tendon. This case highlights the importance of recognizing tendon variations, especially in trauma situations. Detecting such variations preoperatively using imaging can significantly impact the treatment plan and surgical approach.
