is mini-plate removal necessary for oral and maxillofacial surgery patients? a five-year case-control study

Objectives: the purpose of this study was to determine the mini-plate and screw removal rate and reasons in maxillofacial surgery patients under previous semi-rigid fixation treatment in the past five years at the main trauma center of mashhad. materials and methods: this was a census-based retrospective study. all the candidates who admitted to our department for maxillofacial plate removal due to symptomatic or infected mini-plates were included in this study. the patients’ age and gender, plate removal etiologies, and the time between plate insertion and removal were analyzed. results: mini-plates were inserted for 1026 patients. however, only 94 patients with a mean age of 29.4±11.1 years were candidates for plate removal. the plate removal rate was 9.16%. infection and exposure were the most common causes of plate removal. the most prevalent removal site was the mandible (angle and body). the interval between mini-plate insertion and removal was an average of 12.9±5.6 months. it is noteworthy that the shortest lasting duration was when plate removal was secondary to pain (6.67 months) and infection (11.45 months). conclusion: this research showed that the routine removal of plates does not appear to be generally indicated in healthy subjects unless there is an obvious and definitive clinical indication.
