Quality of life in early age Spanish children treated for cleft lip and/or palate: a case-control study approach

Objective The objectives of this study were to evaluate health-related quality of life (HRQoL) in 4-7-year-old children treated for cleft lip and/or palate (CL/P) compared to healthy controls and to estimate a possible association with cleft type, gender, age, and surgical re-interventions. Materials and methods A total of 171 children with CL/P (mean age 5.7 years) and 186 healthy controls (mean age 5.5 years) were included in the study. Sixty-four (37.4%) children experienced both cleft lip and palate, 56 (32.8%) cleft lip only, and 51 (29.8%) cleft palate only. HRQoL in children was assessed by Kiddy-KINDL and COHIP-14 questionnaires and in parents by KINDL-p. Total score and dimensions of each questionnaire were compared between cleft children, their parents, and controls. Results The total scores and dimension scores of Kiddy-KINDL showed similar values between CL/P and control groups, except for "self-esteem" dimension (p = 0.036). The comparison of Kiddy-KINDL and KINDL-p showed a statistically significant total score (82.11 vs. 80.44,p = 0.047). The CL/P group presented significantly worse values with respect to controls in total score of COHIP-14 (10.53 vs 5.01,p < 0.001) and in all its dimensions. Conclusions Children treated for CL/P had a negative impact on HRQoL at early age compared to controls. Significant differences were found in the psychological and functional dimensions related to lip and palatal affectation, respectively. Parents reported significantly worse scores than their children. HRQoL measurement provided valuable complementary information to better inform to parents and make clinical decisions in children with CL/P at early age.
