Abstract

Objectives:

To describe the feasibility and assess the safety of using an ultrasonic bone aspirator in endoscopic ear surgery.

Methods:

Five temporal bones were dissected via endoscopic ear surgery using a Sonopet ultrasonic bone aspirator. Atticoantrostomy was undertaken. Another four bones were dissected using routine endoscopic equipment and standard bone curettes in a similar manner. Feasibility and safety were assessed in terms of: dissection time, atticoantrostomy adequacy, tympanomeatal flap damage, chorda tympani nerve injury, ossicular injury, ossicular chain disruption, facial nerve exposure and dural injury.

Results:

The time taken to perform atticoantrostomy was significantly less with the use of the ultrasonic bone aspirator as compared to conventional bone curettes.

Conclusion:

The ultrasonic bone aspirator is a feasible option in endoscopic ear surgery. It enables easy bone removal, with no additional complications and greater efficacy than traditional bone curettes. It should be a part of the armamentarium for transcanal endoscopic ear surgery.
