OBJECTIVE: This study aims to investigate the immediate effect of straw phonation on the phonation of Persian-speaking children with repaired cleft palate.
STUDY DESIGN: Quasi-experimental preintervention and postintervention.
METHODS: Seventeen children with repaired cleft palate and velopharyngeal dysfunction were investigated. A control group was established comprising children without a cleft palate (control group), carefully matched in terms of age and gender. All participants underwent straw phonation and assessment. The assessments were made two times: at baseline and immediately after straw phonation. Each participant performs straw phonation (a short straw measuring 3 mm in inner diameter and 20 cm in length) once for 3 minutes. The acoustic analysis including parameters, such as jitter, shimmer, harmonics-to-noise ratio (HNR), cepstral peak prominence (CPP) parameters, as well as the electroglottography (closed quotient [CQ]) analysis were performed at pretreatment and immediately after treatment.
RESULTS: Compared with the pretreatment values, after-treatment observation demonstrated a significant reduction in Jitter % and Shimmer %, and a significant enhancement in HNR and CPP among children with repaired cleft palate. There is no significant difference in intragroup data in the CPP and CQ in pretreatment.
CONCLUSIONS: The proposed straw phonation technique results in an immediate positive change in the quality of voice in both groups. Moreover, assessments in the clinical group showed a significant decrease in shimmer and jitter perturbation, alongside elevated levels of HNR and CPP subsequent to straw phonation, irrespective of the phonatory task.
