Abstract

Objective. Rhinophonia is often present in patients with cleft lip and palate (CLP) many years after palatoplasty. It may be caused either by organic deficits, functional disorders, or both. NasalView™ is known as an instrument for the objective assessment of nasalance in cases of velopharyngeal insufficiency or incompetence. However, normative values for the German language are not yet available. In order to overcome this problem, this study evaluated such norms using NasalView™. Methods. A total of 50 individuals with normal speech development were examined with NasalView™. The median age was 14 years (range 11-20 years). The tone material used comprised the vowels /a:/,/e:/,/i:/, /o:/,/u:/, the sentences S1:"Die Schokolade ist sehr lecker." ("This chocolate is very tasty.") and S2:"Nenne meine Mamma Mimmi."("Call my mummy Mimmi."), and the text passages of LT1:"Nordwind und Sonne" ("Northwind and sun"), LT2:"Kindergeburtstag" ("A child's birthday party") and LT3:"Der große Gesang" ("A famous song"). Results. The mean nasalance for the vowels was 35.9% (±8.4), for S1 (containing no nasal consonants) 24.9% (±5.3), and for S2 69.6% (±5.5) (with many nasal sounds). The results for the text passages were 42.1% (±4.2) for LT1, 36.9% (±4.3) for LT2 and 38.2% (±4.4) for LT3. Conclusion. The norms of nasalance for the German language presented here may be useful in measuring the long-term outcome of cleft lip and palate.
