The present study was undertaken to evaluate the efficacy of biodegradable plating system for fixation of maxillofacial fractures and to study the morbidity associated with the use of biodegradable plates and screws.
This prospective study consisted of 10 patients with maxillofacial fractures requiring open reduction and internal fixation. Fractures with infection, comminuted and pathological fractures were excluded. All were plated with biodegradable system (Inion CPS) using standard plating principles and observed for a total period of 24 weeks. Characteristics of the fractures, ease of use of bioresorbable plate/screw system and post operative complications were assessed.
Of total 10 patients, eight patients were of midface fracture and two pediatric patients with mandibular fracture, with nine male and one female. The mean age was 32.8 years. Out of 20 plates and 68 screws applied to the 10 fractures sites; there were three incidences of screw breakage with no other intraoperative difficulties. Paresthesia of the infraorbital nerve was present in two patients, and recovered completely in four weeks after surgery. Fracture reduction was considered to be satisfactory in all cases. One patient developed postsurgical infection and was managed with oral antibiotics and analgesics.
Favorable healing can be observed through the use of biodegradable plates and screws to stabilize selected midface fractures in patients of all ages, as well as mandible fractures in early childhood, however further studies with more sample size are required.
本研究旨在评估可生物降解接骨板系统固定颌面部骨折的疗效，并研究使用可生物降解接骨板和螺钉相关的发病率。
本前瞻性研究包括10例需要切开复位内固定的颌面部骨折患者。排除感染性骨折、粉碎性骨折和病理性骨折。所有患者均采用标准接骨板固定原则使用可生物降解系统（Inion CPS）进行接骨，并观察24周。评估骨折的特点、可生物吸收接骨板/螺钉系统的易用性及术后并发症。
10例患者中，8例为面中部骨折，2例为儿童下颌骨骨折，9例男性，1例女性。平均年龄为32.8岁。在应用于10个骨折部位的20块接骨板和68枚螺钉中，有3例螺钉断裂，术中无其他困难。2例患者出现眶下神经感觉异常，术后4周完全恢复。所有病例骨折复位均满意。1例患者发生术后感染，经口服抗生素和镇痛药治疗。
使用可生物降解接骨板和螺钉可使各年龄段患者的特定面中部骨折以及幼儿下颌骨骨折获得良好愈合，但需要更大样本量的进一步研究。
