Care of the ear canal and mastoid.

Zinc sulfate has been used for therapy of granulations of the trachea and ear that have not responded to usual treatment. This paper will report on current indications for zinc sulfate and the resulting success in managing granulomata of the ear canal and mastoid bowl. Some mastoid bowls have been large and hard to clean, especially in the posterior and lateral parts. A method of cleaning using indirect otoscopy and curved aspirators in conjunction with adequate lubrication will be described. Treatment of otalgia in both the ear canal and mastoid bowl due to otitis externa sicca and results of proper lubrication and avoidance of patient instrumentation to restore the normal wax will also be discussed.
