Removal of external ear canal exostoses by piezo surgery: a novel technique

  • P M Puttasiddaiah (a1) and S T Browning (a1)



External auditory canal exostoses are known to occur in patients who engage in cold-water sports. Although the majority of patients with exostosis remain asymptomatic, larger lesions can cause wax impaction, conductive hearing loss and predispose to recurrent otitis externa.


A novel technique is described of using a piezo saw to excise exostoses that are symptomatic. The piezo saw is used to perform various procedures, but its use in removing exostoses has not been described in the literature.


Excision of exostoses of the ear canal using a piezo saw is a safe technique and patients have a speedy recovery. This paper describes a new technique for removing exostoses.
