Application of Key-hole Plate for Reduction of the facial bone fracture: a Preliminary Study
The Key-hole plate system (Seoul, Korea, Gssem Co.) is a new strategy for the treatment of facial bone fractures using new principles that screws inserted followed by applying plates on the fracture site. The aim of this study is to evaluate clinical outcomes of patients treated by Key-hole plate system and Stabilizations.
Materials and Methods
This study included 13 patients from the Department of Oral and Maxillofacial surgery at the Hallym University Sacred Heart Hospital at July 2013 to March 2014. All cases were treated by Key-hole plate system. Clinical evaluations were performed at 1 week, 2 weeks, 4 weeks, 6 weeks, and 4 months. Postoperative occlusal stability, complications were recorded and evaluated. Panoramic radiographs and cone-beam CT were used for post-operative assessment and at follow-up.
Result
The infection rate was 7.7 % and 1 patient was necessary to remove plate. There were no inferior alveolar nerve injuries after operatations. Minor complications included temporary hypoesthesia on lower lip in 3 cases and temporary occlusal changes in another 3 cases: this condition improved after 1to 3 weeks. Availability of new system was evaluated subjectively by operator.
Conclusion
The Key-hole plate system used in this study was stable for the treatment of facial bone fracture with low complications, easy handling, adjustment, reducing operation time and trauma. The Key-hole plate system was a good alternative for treatment of facial bone fracture.
