Role of Bleomycin Sclerotherapy as a Non-surgical Method for the Treatment of Cystic Hygroma of Head and Neck Region-an Institutional Study

Cystic hygroma is a benign congenital tumor of lymphatic origin. Most common location is head and neck region. Bleomycin is an antineoplastic glycopeptide antibiotic agent with sclerosing property. In our present study, we used bleomycin for intralesional sclerotherapy for cystic hygromas of head neck region, as an alternative to surgical excision. We also statistically analyzed the pattern of cystic hygroma in head and neck region. Our present study was a prospective observational study of 40 patients. The study period was 18 months. All patients were given intralesional bleomycin at the dose of 0.5 mg /kg body weight, not exceeding 10 units at a time. The injection was repeated if required, at an interval of 4 weeks up to 4–5 times. Each patient was followed up at regular interval up to 1 year. Most common age group was found to be between 0–7 years (55%). Mean age was 6.9 years. Posterior triangle of neck was the commonest site (35%). Excellent response was noted in 24 patients (60%) while good response was noticed in 11 patients (27.5%). Poor response in 5 patients (12.5%). No major side effects noted with bleomycin sclerotherapy. No recurrence was noticed in our study. Intralesional bleomycin is a safe, simple, relatively cheaper and effective nonsurgical treatment method for cystic hygroma of head and neck region. It can be used as a first line treatment modality. Still, a lot of research is needed to establish it as a gold standard treatment modality for cystic hygroma.
