[Measurement of nasal airflow and aerophonoscopy].

Diagnosis and treatment of rhinolalia are some of the most important elements in the follow-up of patients presenting with a cleft palate. In order to quantify the nasal airflow, speech therapists use either nasalance-measuring devices or devices related to aerophonoscopy. At the Maxillofacial Surgery Department in the Nantes University Hospital, we are currently trying to evaluate the inter- and intra-individual reproducibility of quantitative values provided by the aerophonoscope. We intend to use this device, originally designed in our department 25 years ago, as a reference tool for the measurement of nasal airflow after cleft surgery.
