Middle ear endoscopy and trans-tympanic drug delivery using an interventional sialendoscope: a feasibility study in human cadaveric temporal bones.

Objectives: The aim of our study was to assess feasibility of using a 1.3mm semi-rigid interventional salivary endoscope for middle ear endoscopy and as a route for trans-tympanic delivery of medication in human cadaveric temporal bones.

Methods: Five temporal bones harvested from human cadavers were examined.
