Abstract
Surgery for lacrimal outflow obstruction may not be the best option in all patients especially in the elderly, medically frail patients and after excision of lacrimal apparatus for treatment of malignant lesions affecting the neighbouring anatomical structures.
Botulinium toxin has been successfully used to treat gustatory hyperlacrimation owing to an aberrant regeneration in proximal facial nerve injuries.
There is scarce evidence showing the usefulness of botulinium toxin in patients with functional epiphora and lacrimal outflow obstruction.
We report favorable outcomes for non-surgical botulinium toxin treatment of lacrimal outflow obstruction.
Epiphora completely resolved in 60%, partialy resolved in 25%, failed in 15%.
