The video demonstrates an ultrasound-guided injection technique for administering therapeutic drugs into the salivary glands of a human patient.
All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board.
1. Procedure
2. BoNT-A injection
NOTE: Use a 22 G needle for injections, with needle penetration at least 0.5 cm from the transducer. The transducer must be oriented longitudinally to the needle so that the needle is visible as a bright echoic line. In this way, the penetration of the needle into the soft tissues can be monitored during the procedure as the needle tip proceeds towards the target, preventing injuries to neurovascular structures.
