“…These authors concluded that the accuracy of LUS increases by using quantitative measures. In turn, a study is currently underway to establish reference ranges for the sizes of individual structures of the larynx and trachea in the neonatal population (24). This study has limitations.…”

Objective: Vocal fold immobility (VFI) is a cause of significant morbidity and mortality in the paediatric population. Laryngoscopy is the current first-line investigation for patients with suspected VFI. Laryngeal ultrasound (LUS) has recently emerged as an alternative method of identifying VFI. Compared to laryngoscopy, LUS is less invasive, does not require anaesthesia, and can be performed by non-otolaryngologists. The primary objective of this study is to evaluate LUS as a diagnostic method for the identification of unilateral VFI in a cohort of paediatric patients in Aotearoa New Zealand (NZ). The secondary objective is to estimate the frequency of use of LUS in the paediatric population around the world. Methods: A retrospective, single-centre cohort study was performed on all paediatric patients who had undergone laryngoscopy and LUS at Starship Children’s Health between 2020 to 2023 in Auckland, NZ. An eight-question survey was also developed and distributed to better understand clinicians’ use of LUS to diagnose paediatric VFI globally. Results: Twenty-three paediatric patients met the inclusion criteria. LUS demonstrated high sensitivity (100%), specificity (63%), positive predictive value (83%), and negative predictive value (100%) for detecting unilateral VFI within our patient population. Out of the eighty-seven respondents to the survey, nearly half utilise LUS in their clinical practice in the paediatric population. The main barrier for those who do not is lack of expertise, equipment, and training. Conclusions: These findings support the use of LUS as a safe and accurate diagnostic tool for the detection of unilateral VFI. Further studies in non-surgical populations and standardised guidelines for LUS technique and reporting are required.

ObjectiveVocal fold immobility (VFI) is a cause of significant morbidity and mortality in the paediatric population. Laryngoscopy is the current first‐line investigation for patients with suspected VFI. Laryngeal ultrasound (LUS) has recently emerged as an alternative method of identifying VFI. Compared to laryngoscopy, LUS is less invasive, does not require anaesthesia, and can be performed by non‐otolaryngologists. The objectives of this study are to evaluate LUS as a diagnostic method for the identification of VFI in a cohort of paediatric patients in Aotearoa New Zealand (NZ) and to estimate the frequency of use of LUS in the paediatric population by clinicians around the world.MethodsA retrospective, single‐centre cohort study was performed on all paediatric patients who had undergone laryngoscopy and LUS at Starship Children's Health in Auckland, NZ, between 2020 and 2023. An eight‐question survey was also developed and distributed to better understand clinicians' use of LUS in their clinical practice to diagnose paediatric VFI globally.ResultsTwenty‐nine paediatric patients met the inclusion criteria. LUS demonstrated good sensitivity (80.95%) for detecting VFI and increased to 93.33% for the detection of unilateral VFI. Of the 87 respondents to the survey, 41.38% utilise LUS in their clinical practice in the paediatric population. The main barriers to implementation of LUS as identified by non‐users were lack of equipment, expertise, and training.ConclusionsThese findings support the use of LUS as an accurate diagnostic tool for the detection of unilateral VFI. Further studies in non‐surgical populations and in patients with bilateral VFI, as well as standardised guidelines for LUS technique and reporting, are required.
