TMJ arthroscopy trocar/cannula set
Fine-gauge (~2mm) sharp trocar punctures the superior joint space via a preauricular approach; a matching cannula is left as the working/irrigation/endoscope channel, with a second cannula as the instrument/outflow portal.
How it is used
Diagnostic and operative TMJ arthroscopy (lysis and lavage, disc repositioning) for internal derangement or pain refractory to conservative treatment.
Clinical tip
Allows direct visualization and more extensive intra-articular procedures than blind double-needle arthrocentesis.
