Published on: May 23, 2021
[The technique of endaural drainage of the antrum]
Abstract:
Antrodrainage methods are reviewed. To easy endaural drainage, a special drill is proposed. It has been used for trephine puncture of the antrum in 60 patients (55 with otitis purulenta chronica and in 5 with exudative otitis media). Positive diagnostic and therapeutic significance of endaural drainage as well as necessity of its further perfection and wider usage in practice are emphasized.
