Transeustachian Middle Ear Endoscopy Using a Steerable Distal-Camera Tipped Endoscope.

ABSTRACT:

Objective

Demonstrate the ability of a novel steerable distal chip endoscope to traverse the Eustachian tube and provide diagnostic quality images of the human middle ear.

Patients

Three cadaveric temporal bone specimens were used in this work.

Intervention

Diagnostic transeustachian endoscopy of the middle ear was performed.

Main outcome measure

Diagnostic image quality.

Results

A novel 1.62 mm steerable endoscope successfully cannulated the Eustachian tube of three human cadaveric temporal bone specimens to reveal intact middle ear anatomy with high optical clarity.

Conclusions

A steerable endoscope can be designed to traverse the human Eustachian tube and provide diagnostic quality images of middle ear anatomy.
