[Application status and prospect of botulinum toxin A in otorhinolaryngological treatment]
Abstract:
Botulinum toxin A is a kind of neurotoxin produced by clostridium botulinum, and has been applied for nearly thirty years in China.The target of BTX-A is to selectively cleave the synaptosome-associated protein of 25 KD molecular mass, commonly abbreviated SNAP-25, thereby inhibiting neurotransmitter release and causing chemodenervation. The potential application of botulinum toxin A in treating the spasmodic dysphonia, hemifacial spasm, tinnitus, rhinitis has been confirmed both in clinical practice and previous studies. This paper is to review comprehensively the application status and the prospect of botulinum toxin A in otorhinolaryngological treatment.
