Description of intervention(s) / exposure
Phase I Clinical Voice Assessment: the voice quality of 200 very preterm children with dysphonia will be clinically assessed at a single timepoint at school age. Clinical assessment will consist of an acoustic analysis of voice quality, perceptual ratings of voice quality, a quality-of-life questionnaire to be completed by a caregiver and a self-report questionnaire to be completed by the child. This assessment will take between 30 and 45 minutes, depending on the clinical presentation and discussion.

A number of medical variables will be determined via retrospective chart review. These include: birthweight, gestational age, frequency of intubation, duration of intubation and tube size to body weight ratio.

Phase II Fibreoptic Endoscopic Evaluation of Laryngeal Function: participants presenting with moderate to severe dysphonia will be offered a fibreoptic endoscopic evaluation of laryngeal function at a single time point. This evaluation will take approximately 30 minutes in total.
