RESUMEN
INTRODUCTION: This study investigated the effects of suspension pharyngeal flap surgery for velopharyngeal insufficiency (VPI) due to cleft palate. METHODS: Ten Filipino individuals (mean age = 20.63 years, range = 8.4 to 34.9 years) with a cleft palate who underwent suspension pharyngeal flap surgery for VPI were included in this study. Perceptual and instrumental speech assessments were conducted at two different time points: before surgery (data point 1) and after surgery (data point 2, range = 4 to 26 weeks post-operatively). Speech intelligibility in different contexts and satisfaction with speech were assessed by the participants themselves using a self-report questionnaire. Additionally, the risk for obstructive sleep apnea was assessed using the The Berlin Questionnaire. RESULTS: Velopharyngeal gap size significantly decreased after the surgery. Additionally, significant improvements in speech understandability and acceptability were observed following the suspension pharyngeal flap procedure. Besides, a significant reduction in hypernasality, nasal emission, and the occurrence of passive articulation errors was seen. No difference in the occurrence of active articulation errors was observed when comparing data pre- and post-surgery. The ten individuals reported to be significantly more intelligible in different contexts after surgery. CONCLUSION: Improved speech was observed in individuals who received the suspension pharyngeal flap procedure. This procedure also positively influences an individual's intelligibility in different contexts in daily life. In individuals with persisting active articulation errors, post-surgery speech therapy will still be necessary.
RESUMEN
INTRODUCTION: Children with malocclusion, combined with orofacial myofunctional disorders (OMDs), show increased risk of developing orthodontic problems and needs later in life. Speech-language therapists typically provide orofacial myofunctional therapy (OMT) after referral by dentists, orthodontists or ENT specialists. Interdisciplinary treatment is often advisable to prevent relapse after orthodontic treatment. OMDs and OMT are often found to be controversial topics by dentistry professionals. This study aimed to investigate self-reported knowledge and attitudes of Flemish dentists and orthodontists towards OMDs and OMT. METHODS: A survey containing 32 items on demographics, self-reported knowledge of OMDs and OMT, attitudes towards OMDs, OMT, and its use in clinical practice, and referral behaviour was filled out by 48 general dentists (48/79, 61%) and 31 orthodontists (31/79, 39%). The impact of specialization, degree of experience and educational programme was also evaluated. RESULTS: Fifty-six percent of all participants (44/79) reported insufficient to non-existent knowledge of OMT. Nevertheless, the general attitude towards the use of OMT was neutral (47%, 37/79) to (very) positive (48%, 38/79). Although they found correct, evidence-based knowledge on OMDs and OMT important, the majority indicated their formal training did not provide adequate information on OMDs (52%, 41/79) and OMT (62%, 49/79). Specialization showed significant effects, as orthodontists reported themselves knowledgeable on this topic significantly more often than general dentists (p < 0.001), and generally reported a more positive stance towards OMT (p = 0.022). CONCLUSION: Dentists and orthodontists indicated a general interest in the topic of OMDs and OMT, alongside an overall lack of information provided by formal education. Current findings suggest the necessity of re-evaluating current curricula on OMDs and OMT.
