The impact of orthognathic surgery on quality of life in individuals with oral clefts.

Background/objectives: To evaluate the relationships between individual, environmental, clinical factors and oral health-related quality of life (OHRQoL) in patients with cleft lip and palate (CLP) following orthognathic surgery.

Materials And Methods: A follow-up study was conducted involving 69 adults with unilateral and bilateral CLP under orthodontic treatment. Interviews and oral examinations were conducted prior to orthognathic surgery (T0) to evaluate age, gender, psychological well-being, dental caries, malocclusion, social support, social networks, family income and education and OHRQoL. All participants were reviewed after 6 months (T1) to re-assess psychological well-being, malocclusion and OHRQoL. Structural equation modeling estimated the associations between the variables.

Results: OHRQoL total scores reduced following orthognathic surgery, from 11.7 to 6.9 (P < 0.01). Occlusal characteristics and psychological well-being improved between T0 and T1. In the structural equation modeling, reduction of malocclusion (β = 0.02) between T0 and T1 directly predicted poor OHRQoL at T1. Improvement of psychological well-being between T0 and T1 was associated with better OHRQoL at T1 (β = -0.07). Dental caries and malocclusion at T0 were indirectly linked to poor OHRQoL at T1 (β = 0.02).

Limitations: The short follow-up period of 6 months after orthognathic surgery.

Conclusions/implications: This represents the first prospective study examining the interrelationships of predictors of OHRQoL in patients with CLP after orthognathic surgery. OHRQoL and psychological well-being improved after orthognathic surgery. Clinical and psychological characteristics were important determinants of OHRQoL. These findings suggest the importance of the biopsychosocial model of health and the patient-centered approach in oral health care in individuals with CLP.
