Introduction: Sialendoscopy is a recent advancement in the treatment of paediatric obstructive salivary gland disease. We examined the variance of paediatric sialendoscopy by ethnicity, using data from our tertiary sialendoscopy service in Counties Manukau Health (CMH). There is evidence of a Māori predominance for paediatric salivary ranulas (1) and we sought to examine whether ethnicity is also a factor in other paediatric salivary disease.
Aims: To provide the descriptive epidemiology relating to paediatric sialendoscopy for recurrent sialadenitis in South Auckland.
Methods: A retrospective review of paediatric (age < 15 years) sialendoscopies performed at the Manukau Surgery Centre, CMH from April 2010 to April 2020 was conducted. The 2013 New Zealand Census was used for population demographics. CMH-domicile patients only were analysed separately for crude and age-specific annual incidence rates. Sub-analyses by ethnicity was performed to identify ethnic disparities.
Results: A total of 55 sialendoscopies were performed in 38 unique patients. The indication for sialendoscopy was juvenile recurrent parotitis (JRP) (76.3%) or sialolithiasis (23.7%). Sialolithiasis was found only in the NZ European/Other ethnicity children. The incidence rate (CMH residents) for JRP was 2.2 per 100,000 person-years (95% CI: 1.3, 3.1), and 0.4 per 100,000 person-years (95% CI: 0.0, 0.8) for sialolithiasis. The age-adjusted incidence rate for JRP was highest in Māori (4.4 per 100,000, 95% CI: 1.7, 7.1), followed by Pacific Island (2.1 per 100,000, 95% CI: 0.4, 3.8) and NZ European/Other (1.4 per 100,000, 95% CI 0.4, 2.4).
Conclusions: This study quantifies incidence rates of diseases requiring paediatric sialendoscopy. The most common indication was JRP, which affected Māori more than other ethnic groups. The results suggest an underlying predisposition for JRP in Māori, although the reasons are as yet unclear.
