OBJECTIVES To measure the degree of tongue tie presenting to a dedicated clinic in a tertiary paediatric university hospital, to report the variety and severity of issues encountered by carers, to measure a single surgeons practice by pre and post carer survey and to report complications. METHODS All patients who underwent tongue tie release at a single surgeons’ practice over one year were included. Tongue tie was assessed and scored by a single operator on a 4 point scale. Carers filled in a questionnaire pre and post operatively at an interval of 1 month for comparison. Students paired t test was used to analyse the difference between groups. RESULTS Fifty four patients underwent tongue tie release. The mean age at procedure was 2 months. The most common type of tongue tie was type 3 (27), followed by type 2 (19). The mean score of overall problem pre procedure was 6.92 (SD 1.92) and post procedure was 2.52 (SD 2.45), the mean difference was 4.46 points (SD 3.10). The difference in pre and post procedure scores was significant (p<0.001, 95% CI, 3.56 – 5.36). Two patients experienced mild self limited bleeding post operatively that was managed conservatively. CONCLUSION Tongue tie release is a safe and effective procedure when performed in the correct setting with the appropriate experience. The greatest effect is seen in type 2 and 3 tongue tie groups. Improvements are noted on subjective feeding scales as well as visual analogue scales.
