Evaluation of Nerve Innervation Distribution of Orbicularis Oculi Muscle for Botulinum Neurotoxin Application Using Sihler's Method

CONCLUSION: This study unveiled the nerve branches associated with the orbicularis oculi muscle. It pinpointed precise crossing points of these nerve branches, which can be targeted for applying BoNT in treating blepharospasm. Consequently, by utilizing minimal BoNT, it is anticipated that the quantity of toxin administered will decrease, leading to more efficient outcomes and reduced expenses. Furthermore, this approach can aid in averting potential undesired complications during BoNT administration.PMID:37804929 | DOI:10.1016/j.aanat.2023.152165
