    Abstract:
    OBJECTIVE: The basic objective of this study was to find out the efficacy of OK-432 for the conservative treatment of lymphangiomas of head and neck regions at the Department of ENT-Head & Neck Surgery of Tribhuvan University Teaching Hospital (TUTH), Kathmandu, Nepal. METHODS: It was a hospital based prospective, cross-sectional, case series, conducted among the patients suffering from different lymphangiomas of head and neck regions and treated with intra-lesional injection of OK-432, from March, 2005 to September 2006. Altogether eleven patients were enrolled in this modality of treatment out of which one patient was excluded from the study, which was treated surgically due to very ugly scar at the site of lesion resulting from previous surgery for the same. The data were analyzed by using simple mathematical tools like percentage and frequency. RESULTS: Out of ten patients treated with intralesional injection of OK-432, absolute response, i.e. total resolution of swelling was found in nine patients (90%) after the first dose. Remaining one patient also responded well on the treatment but some residual swelling was in situ for which second dose was given. After the second dose it was also totally resolved. In this way we achieved 100% response after the second dose of OK-432. CONCLUSION: The results of this study so far indicate that OK-432 is an effective and safe tool for the treatment of lymphangioma of head and neck region. As the procedure can be done in an out patient department, without hospitalization and has got minimal side effects, it can be proposed as the first line treatment of lymphangiomas of head and neck.
