Personal experience is discussed in the use of botulinum neurotoxin injections into both parotids, performed in order to transiently reduce salivation in patients undergoing major ablative and ablative-reconstructive oncologic surgery for head and neck tumours. Overall, 8 adult patients (2 female, 6 male) have been treated. Six cases were affected by pharyngocutaneous fistulas, one by severe sialorrhoea and one recurrent sialocele. After the injection, patients were regularly observed at follow-up and asked to give their subjective assessment of salivary flow. Investigations concerning possible complaints, including side-effects, as well as complete examination of the head and neck area were performed. Follow-up periods ranged from 12 to 24 weeks (mean 20 weeks). Following botulinum neurotoxin injection, the fistula was dry after a mean period of 4.5 days (min 3 days, max 8 days) and was closed 6.6 days (min 5 days, max 8 days) later. The patient affected by severe hypersalivation reported subjective improvement in sialorrhoea 4 days post-treatment. The patient affected by recurrent sialocele, required only one aspiration of fluid two days after the treatment, after which there were no further problems. Post-operative saliva-related complications significantly increase patient morbidity and hospital stay after major tumour surgery. The easy, safe and effective treatment with botulinum neurotoxin injection, observed in our experience, suggest its significant role as a useful option in the post-operative saliva-related complications.
