Objective:
The aim of this study was to investigate the incidence of plate removal in orthognathic surgery patients and the reasons for their removal and to potentially identify the factors that may contribute to it.
Methods:
A retrospective study included all patients who underwent orthognathic surgery at Selayang Hospital from January 2011 to December 2017. The variables of interest recorded included patient age, gender, the existing skeletal deformity, type of surgery undertaken and number and location of plates inserted and removed. In addition, the reasons for plate removal and duration between plate insertion and removal were also recorded.
Results:
Ninety-seven patients with a mean age of 21.33 were included in the study. Nine patients with total of 33 plates had their miniplate fixation removed. Three patients underwent bi-maxillary surgery, and six patients underwent BSSO. The average time from insertion to removal was 22.33 months. The reasons for removal included pain, palpable and exposed plates, infection and on patient request.
Conclusion:
We report a 9.28% incidence of plate removal in patients who undergo orthognathic surgery which is comparable to the existing literature.
