Introduction: BiZactTM is a new ligasure device to perform a tonsillectomy efficiently with less intra-operative bleeding. It utilises bipolar to seal blood vessels followed by division of tissue. This technique markedly reduces operation time compared to traditional cold steel tonsillectomy. The Paediatric Throat Disorders Outcome Test (T-14) is a validated outcome measure used to assess the quality of life in children undergoing surgery. However, the T14 has never been used to assess the outcomes of BiZactTM tonsillectomy.

Aims: To assess the efficacy of BiZact tonsillectomy using the T-14 questionnaire.

Methods: A prospective cohort study of patients who underwent BiZactTM tonsillectomy in South Australia between 2017 and 2018 was conducted. Estimated intra-operative bleeding and operative time was measured. The parents were invited to complete the T-14 questionnaire pre-operatively and 6 weeks post BiZactTM tonsillectomy. A paired t-test was used for statistical analysis.

Results: One experienced consultant otorhinolaryngologist and two otorhinolaryngology registrars performed BiZactTM tonsillectomy on 70 patients. The median reduction in T-14 scores between the pre-operative and 6-week post-operative group is 22 - indicating a significant improvement in the parental perception of the child’s quality of life following BiZactTM tonsillectomy (p<0.0001). Mean operative time was 4.8 minutes. Mean estimated intra-operative blood loss was 2.7ml. The rate of secondary haemorrhage was 4.3%.

Conclusions: This study demonstrates that there is significant improvement in T-14 scores following BiZactTM tonsillectomy. It appears to be an effective technique of performing the most common surgical procedure in otorhinolaryngology.
