Speech after repair of isolated cleft palate and cleft lip and palate

The speech of children with isolated cleft palate (CP) repaired by one surgeon has been compared with the speech of children with some form of unilateral cleft lip and palate (CLP) repaired by the same surgeon. All palate repairs included an intravelar veloplasty. We identified 57 children (5--12 years old) with cleft palates repaired in infancy, of which three patients with other medical problems were excluded. Of the 54 patients, 44 (81%) attended for review (27 CP, 17 CLP). Video recordings were analysed by two speech and language therapists, using the Cleft Audit Protocol for Speech. The CP patients had no evidence of permanent fistulas. Final speech outcomes were similar for CP and CLP patients. Intelligibility was normal in 10 (37%) CP and nine (53%) CLP patients. Mild consistent hypernasality was present in five (18.5%) CP and four (23.5%) CLP patients. No patients had moderate or severe hypernasality or nasal emission. Mild consistent hyponasality was present in five (18.5%) CP and five (29%) CLP patients. Moderate consistent hyponasality was present in one (4%) CP patient. Dysphonia was present in eight (30%) CP and seven (41%) CLP patients. Cleft-type characteristics were noted in 11 (41%) CP and nine (53%) CLP patients. No CLP patients but 10 (37%) CP patients had required a pharyngoplasty (P=0.004, Fisher's exact test). Possible reasons for this (age, cleft type, surgeon and surgery) are discussed.
