Objective
To investigate long-term, longitudinal speech outcome in patients born with unilateral cleft lip and palate treated according to a two-stage primary palatal protocol with early veloplasty and delayed hard palate closure.
Design
Retrospective, longitudinal cohort study.
Setting
A university hospital in western Sweden.
Subjects
A consecutive series of 55 patients from the total cohort of 65 were included. All patients had surgical procedures at Sahlgrenska University Hospital, Gothenburg, Sweden.
Methods
Standardized audio recordings were blindly analyzed at 5, 7, 16, and 19 years of age and after at a clinical visit at 10 years of age. Typical cleft speech variables were rated independently on ordinal scales. Intelligibility and perceived velopharyngeal function were assessed also. Prevalences of speech characteristics were determined, and interrater and intrarater agreement were calculated.
Results
Prominent hypernasality, nasal air leakage, and retracted oral articulation at 5 years were markedly reduced throughout the years with low prevalences at ages 16 and 19 years. Perceived velopharyngeal competence was noted in 82% at age 16 and 87% at age 19 years along with normal intelligibility. Pharyngeal flap surgery was performed in 6 of the 55 patients (11%).
Conclusions
Long-term speech outcome in patients with two-stage palatoplasty with early soft palate repair was considered good and improved even before hard palate repair. The typical retracted oral articulation was quite frequent during the early ages; whereas, nonoral misarticulations were almost nonexistent, implying good velopharyngeal competence.
Delayed hard palate closure as practiced in Goteborg since 1979 has produced the best GOSLON Yardstick ratings in a consecutive series of patients ever recorded worldwide, since the Yardstick was first used in 1983. However, it is noteworthy that a new protocol has been introduced in Goteborg since 1994, in which hard palate closure is done at 3 years due to concerns regarding speech.
We wanted to find out if different timing of delayed repair of the hard palate in a two-stage procedure had an impact on the speech of 26 patients with unilateral cleft lip and palate (UCLP). The soft palate was closed at the age of 7 months and the hard palate between 38 and 89 months of age. Speech audio recordings at the age of 3 years (baseline, before any repair of the hard palate) and at the ages of 5, 7, and 10 years (the latter obtained at least one year after closure) were analysed. We used standardised speech assessments at routine follow-up and assessment by one external listener. The prevalence of speech errors caused by the cleft was similar to those described in previous reports from our centre in which hard palate repair was delayed. Unexpectedly, the results showed no difference in speech production related to timing of hard palate repair, except for nasal air leakage at the age of 7 years.
