PROGRAM DESCRIPTION: This surgical video features a procedure for the shaping of the tympanomastoidal cavity and dissection of an obliterated cochlea using the piezoelectric instrument. Given the intricate and complex topographic anatomy of the temporal bone, the piezoelectric bone surgery offers a higher safety profile and a more precise bone removal working in close proximity to soft tissue when compared to the conventional drill. The microoscillations of the instrument tip lead to microfractures of the sclerotic bone of the ossified cochlea, which, in combination with the simultaneous irrigation coming directly from the insert, prevents smearing of bone dust in the cochlear scalae and allows for an optimal surgical view. The application of piezoelectric instrument in temporal bone surgeries aids in creating safe and precise bone removal with angled inserts over the facial nerve and the sigmoid sinus without the complete exposure of these structures from compact bone, highlighting an advancement in facial nerve protection in temporal bone surgeries.
