Assessment of changes in quality of life in patients with Dentofacial deformities after orthognathic surgery-A study in Nepalese population

Objective: To assess the changes in quality of life of Nepalese patients with Dentofacial deformities after orthognathic surgery using generic health related, short form oral health impact profile and condition specific quality of life questionnaires. Methods: Fourteen patients who underwent orthognathic surgery were assessed pre-operatively (P0) and eight to twelve months post-operatively. Short form health survey (SF-36), short form oral health impact profile (OHIP-14) and orthognathic quality of life questionnaires (OQLQ) was used to assess generic health related quality of life, generic oral health related quality of life and condition specific quality of life respectively. Results: There was significant (P < 0.05) improvement in role limitation due to physical health, role limitation due to emotional well being, energy/fatigue and social function after surgery. There was significant decrease (P < 0.05) in five out of seven domain score of OHIP-14 as well as overall OHIP-14 score. Similarly all domain scores of OQLQ also showed a significant (P < 0.05) decrease in their score suggesting improvement of quality of life post orthognathic surgery. Conclusion: Significant improvement in QOL occurs after orthognathic surgery when carried out in patients with dentofacial deformities. (c) 2017 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI.
