Evaluation of Quality of Life After Orthognathic Surgery in a Cleft Lip and Palate Context (ORTHOQOL)

May 13, 2026 updated by: University Hospital, Lille
The purpose of this study is to compare, prospectively, the quality of life of patients with cleft lip and palate before and after orthognathic surgery. This is done through two validated questionnaires: OHIP-14 (Oral Health Impact Profile) and OQLQ (Orthognathic Quality of Life Questionnaire) Improving the quality of life is the goal of any functional treatment. The demonstration of its improvement would validate the validity of this additional surgery for patients with cleft lip and palate.
