Sublabial gland biopsy is the 'gold standard' in establishing the diagnosis of primary Sjögren's syndrome. Bleeding and nerve damage are complications. Our centre has adopted the use of the chalazion clamp to provide a dry surgical field to address these challenges. This study aimed to assess the accuracy of minor salivary gland harvest rate using this technique.
A retrospective review of all minor salivary gland biopsies was carried out in a single tertiary referral centre over a five-year period.
Forty-one biopsy patients were identified, with a mean age of 56.1 years. There was 100 per cent accuracy in harvest rate in our series. Twelve patients (29 per cent) were positive for primary Sjögren's syndrome. No patients had a complication immediately or at one month follow up.
Dry surgical field sublabial gland biopsy is a safe and highly effective technique in the diagnosis of primary Sjögren's syndrome. Initial results indicate it may provide a higher harvest rate with fewer complications than traditional non-ischaemic techniques.
