The Efficacy of Hyaluronidase in Early Surgery of Nasal Bone Fracture.

A nasal bone fracture is one of the most common facial injuries and is often treated by closed reduction. Typically, 2 to 3 weeks are needed for patients to return to daily life because the operation is performed after swelling around the fracture site is reduced. This study aimed to investigate that hyaluronidase injection could reduce swelling, perform early operation and return to daily life accelerated.From January 2017 to December 2017, 181 patients with nasal bone fracture were analyzed. 60 patients underwent hyaluronidase injection and massage to reduce edema, then performed surgery within 2 to 4 days. The remaining patients were treated conservatively (massage alone); they then underwent surgery. Ultrasonography was used to measure changes in skin thickness, and the treatment duration, outcome, and patient satisfaction were compared.The duration from injury to surgery was short in the early operation group, and the period of recovery and return to ordinary life was significantly shorter than in the conventional group. The difference in skin thickness after hyaluronidase injection and massage was 0.8 mm in the early operation group; there was no significant difference in the conventional group. There was no statistically significant difference in satisfaction between the 2 groups, but the mean satisfaction was higher in the early operation group.In patients with nasal bone fracture after facial trauma, hyaluronidase injection, and massage led to reduced edema. This might improve patient satisfaction by allowing earlier operation and earlier return to daily life.

Comparison of Postoperative Outcomes Between Monitored Anesthesia Care and General Anesthesia in Closed Reduction of Nasal Fracture.

Fracture of nasal bone is among the most common facial bone fractures. Reduction of nasal bone fracture is able to be performed under local or general anesthesia. The aim of this study is to compare monitored anesthetic care (MAC) and general anesthesia (GA) based on intraoperative vital signs, and the adverse effects after closed reduction of nasal bone fractures.The authors performed a retrospective study of 45 patients who underwent a closed reduction of nasal bone fracture between January 1, 2016 and December 31, 2016. Patients are divided into an MAC group (n = 17) or GA group (n = 28). A sore throat, postoperative pain scores, nausea, vomiting, hospital stay, operation time, and the result of surgery are compared between the groups. All the patients have interviewed their satisfaction of aesthetic and functional outcome.The operation time and hospital stay were lower in the MAC group. There is no difference in a sore throat, postoperative pain score, and the result of surgery significantly. In the MAC and GA groups, there was no statistically significant difference in the postoperative cosmetic and functional satisfaction scores.Closed reduction of nasal bone fracture using MAC is as safe and efficient as GA. However, MAC anesthesia may not be feasible if airway discomfort due to bleeding is expected, or fracture is severe and multiple manipulations are required. Therefore, MAC is considered to be a good alternative when patients undergoing short-term or small operations do not prefer general anesthesia.
