Assessment of quality of life in patients undergoing orthognathic surgery.

Clinical Question: Analysis to date on the impact of a pronounced skeletal dentofacial deformity on quality of life remains inadequate.

Objective: The objective of this study was to introduce a validated and internationally comparable questionnaire for the assessment of quality of life, and to use this questionnaire in a consecutively-selected patient cohort.

Material And Methods: The Orthognathic Quality of Life Questionnaire (OQLQ) used internationally was translated into German and adapted in accordance with EU guidelines (OQLQ-G).
