Endoscopically Assisted Drilling, Exposure of the Fundus through a Presigmoid Retrolabyrinthine Approach: A Cadaveric Feasibility Study.
The presigmoid retrolabyrinthine approach to the cerebellopontine angle is traditionally described to not provide access to the internal auditory canal (IAC). We aimed to evaluate the extent of the IAC that could be exposed with endoscopically assisted drilling and to measure the percentage of the IAC that could be visualized with the microscope and various endoscopes after drilling had been completed. Presigmoid retrolabyrinthine approaches were performed bilaterally on 4 fresh cadaveric heads. ⋯ The microscope afforded a mean view of 83% (n = 8) of the IAC. The 0°, 30°, 45°, and 70° endoscope each afforded a view of 100% of the IAC in 8 of 8 temporal bone specimens. In conclusion, endoscopic drilling of the IAC of can provide an extradural means of exposing the entire length of the IAC while preserving the labyrinth.

Case ReportsA Novel Approach to Oropharyngeal Foreign Body Removal.
Grill wire brush bristle foreign bodies most commonly embed in the oropharynx. Often these bristles can be removed in the clinic; however, on occasion, the patient requires general anesthesia for retrieval because of the gag reflex and difficulty with access and visualization. We report here on 2 cases of patients who underwent successful transoral robotic surgical retrieval of wire bristles from the base of tongue after unsuccessful direct laryngoscopy. Otolaryngologists should be aware of the use of robotic assistance for oropharyngeal foreign body retrieval.
