RESUMEN
OBJECTIVE: This study sought to evaluate long-term dental arch relationships in adults with a unilateral complete cleft lip and palate (UCLP) treated by the Utrecht protocol and to compare results with the centers from the Eurocleft study. MATERIALS AND METHODS: Retrospective analysis of UCLP patients age 17 or older, treated by two-stage palate closure at the Wilhelmina Children's Hospital, a tertiary center for cleft surgery in Utrecht, the Netherlands. Patients were invited to the clinic for a long-term evaluation. Casts were obtained on the day of follow-up and assessed by the modified Goslon Yardstick for permanent dentition. Dental casts were scored twice by 3 different examiners. RESULTS: Intra-rater agreement varied from 0.743 to 0.844, the inter-rater agreement from 0.552 to 0.718. The mean Goslon Yardstick score was 3.3. Thirty-three percent of the patients had a Goslon score of 1 or 2, 45% had a score of 4 or 5. CONCLUSIONS: The present study found unfavourable results regarding dental arch relationships after delayed hard palate closure at 3 years old. The mean Goslon Yardstick score was 3.3 (SD 1.4) and 45% of the casts were allocated to group 4 or 5 despite extensive orthodontic treatment. We observed a high number of secondary surgical interventions but no evident benefit regarding dental occlusion following the Utrecht treatment protocol, which includes a two-stage palatoplasty. Other factors than the timing of palate closure are likely of influence.

BACKGROUND: No consensus exists on the optimal treatment protocol for orofacial clefts or the optimal timing of cleft palate closure. This study investigated factors influencing speech outcomes after two-stage palate repair in adults with a non-syndromal complete unilateral cleft lip and palate (UCLP). METHODS: This was a retrospective analysis of adult patients with a UCLP who underwent two-stage palate closure and were treated at our tertiary cleft centre. Patients ≥17 years of age were invited for a final speech assessment. Their medical history was obtained from their medical files, and speech outcomes were assessed by a speech pathologist during the follow-up consultation. RESULTS: Forty-eight patients were included in the analysis, with a mean age of 21 years (standard deviation, 3.4 years). Their mean age at the time of hard and soft palate closure was 3 years and 8.0 months, respectively. In 40% of the patients, a pharyngoplasty was performed. On a 5-point intelligibility scale, 84.4% received a score of 1 or 2; meaning that their speech was intelligible. We observed a significant correlation between intelligibility scores and the incidence of articulation errors (P<0.001). In total, 36% showed mild to moderate hypernasality during the speech assessment, and 11%-17% of the patients exhibited increased nasalance scores, assessed through nasometry. CONCLUSIONS: The present study describes long-term speech outcomes after two-stage palatoplasty with hard palate closure at a mean age of 3 years old. We observed moderate long-term intelligibility scores, a relatively high incidence of persistent hypernasality, and a high pharyngoplasty incidence.
