A practical technique for tympanocentesis for culturing aerobic and anaerobic bacteria.

Tympanocentesis is a method frequently used to aspirate middle ear fluid from infected ears. There are some medical indications to perform tympanocentesis in certain clinical settings.1 This procedure could be beneficial in some patients in which determination of the etiology of the acute otitis media and relieving the pain and acute symptoms is of importance. The instrument frequently used by otolaryngologists is the Senturia ear specimen collector (Storz Instrument Company, St Louis) which operates by controlled suctioning using an external negative pressure. A simplified method for performing myringotomy and tumpanocentesis2 that avoids the use of complicated equipment and prevents contamination of the specimen is presented here.
