Does topical use of autologous serum help to reduce post tonsillectomy morbidity A prospective controlled preliminary study

OpenAlex English

BACKGROUND: To evaluate the effects of autologous serum usage on throat pain, haemorrhage and tonsillar fossa epithelisation in patients after tonsillectomy. METHODS: Thirty-two patients (aged 4-15 years) were included in the study. Tonsillectomy was performed and autologous serum was administered topically to the right tonsillar fossa during the operation, and at 8 and 24 hours post-operatively. The left side served as the control. A visual analogue scale was used to record the patient's pain every day. Each patient's oropharynx was observed on the 5th and 10th post-operative days to examine bleeding and epithelisation. RESULTS: The pain scores for the side administered autologous serum were significantly lower than those for the control side, on the night following the operation and on the 1st, 2nd, 5th and 6th post-operative days. Tonsillar fossa epithelisation was significantly accelerated on the study side compared with the control side on the 5th and 10th post-operative days. CONCLUSION: In tonsillectomy patients, topically administered autologous serum contributed to throat pain relief and tonsillar fossa epithelisation during the post-operative period.
