Trans-nasal injection of botulinum toxin

Abstract

AbstractIntroduction:Office-based laryngeal injection for the treatment of a variety of voice disorders is an established practice. Various methods of delivery to the vocal folds are in practice.Aim:We present a simple and repeatable method of injecting botulinum toxin into the larynx.Method:Botulinum toxin A (Botox®) was delivered into the larynx using a channelled fibre-optic laryngoscope under local anaesthetic, in an office setting.Results:Seven patients received regular botulinum toxin injections, via our preferred method. The treatment intervals and dosage regime varied depending on patient requirements. The procedure was carried out in an office setting, with minimal discomfort and inconvenience to the patient.Conclusion:We present a method of botulinum toxin delivery to the larynx which is simple, easily repeatable and simply learnt by the otolaryngologist familiar with fibre-optic laryngoscope usage. This method is also comfortable and convenient for the patient.
