Assessment of preoperative and postoperative quality of life of 24 patients with fibrous dysplasia of the mandible.

The aims of this study were to compare preoperative and postoperative quality of life (QoL) in 24 patients with fibrous dysplasia of the mandible, and evaluate the effects of two surgical techniques on their postoperative QoL. Their QoL was assessed using the University of Washington Quality of Life (UW-QoL) questionnaire. The patients was divided into two groups according to the two different surgical techniques used. The first group (n=11) were managed with focal bone modification, and their results compared with those of the other group (n=13) who were managed with total resection of the focal bone. Their total postoperative QoL score of patients was significantly higher than that of the preoperative period (p=0.035). The postoperative scores for activity (p=0.004), recreation (p<0.001), chewing (p=0.03), and speech (p=0.001) were significantly lower than those before operation, and those for pain (p<0.001), appearance (p<0.001), mood (p<0.001), and anxiety (p=0.001) were significantly higher. The change in scores for each patient (between before and after the operation) also differed. The UW-QOL can be used to evaluate the QoL of patients with fibrous dysplasia of the mandible, and operation can improve it. Different surgical techniques have a significant influence on patients' QoL.
