Abstract
Quality of life is a valid patient-reported parameter that provides an assessment of treatment need or outcomes complementary to standard clinical measures. Such patient-reported assessments are particularly salient when examining chronic conditions with prolonged treatment trajectories, such as cleft lip and palate. This critical review identifies key questions related to ongoing research on the oral health–related quality of life (OHRQoL) in children with cleft and caregiver well-being. Details of the design and results from 2 longitudinal multicenter studies are presented. This article also provides an update on recent published reports regarding OHRQoL in individuals with cleft. Methodological issues in OHRQoL research are discussed, including condition-specific versus generic instruments, incorporating positive items in OHRQoL instruments, calculating minimally important differences in OHRQoL, implementing mixed methods design, and utilizing validated short assessment forms in OHRQoL research. Finally, new directions for research in cleft as a chronic condition are identified and discussed.
