Mastoid Antral Ventilation Tube
First Claim
1. The invention relates to a mastoid antral ventilation tube, which is used in the treatment of the diseases related with the insufficiencies of aeration in middle ear, helps eliminate the inequilibrium of the inner ear fluids, enables the drug treatment for the diseases of middle and inner ear, makes it possible to aerate and drain the middle ear cleft via mastoid mitral path without disrupting the integrity of the eardrum, increases the success of the middle ear operations and is developed for placement into mastoid antrum, and it is characterized in that it comprises an external cannula (1) made up of the tab (1.1), neck (1.3), bend (1.4) and shaft (1.5) sections, and an inner cannula (2) made up of a thin and narrow canal (2.1) with a syringe-adapted-tip for drug administrations and the drainage canal (2.2) that provides the drainage-aspiration of mastoid antrum (10) with one end capable of extending up to mastoid antrum (10) via external cannula (1).

Abstract
In its broadest form, this invention enables the ventilation and drainage of the middle ear cleft via mastoid antral route, without disrupting the integrity of the eardrum. For this purpose, this tube is placed between mastoid antrum and the external ear canal after mastoidotomy (antrotomy). The tube has two cannulas, which are placed one within the other. One of these is the external cannula and it comprises a head portion made of a circular tab, a neck portion in a vertical plane to the head portion, the bent section making a right angle of 90 degrees and a longer shaft portion. Other cannula is the internal cannula and it comprises a thin, narrow and syringe-adapted-tipped canal and the canal used for the aspiration and drainage of the rest of the lumen. The external tip of the inner cannula proceeds from the external ear canal and ends pre- or retroauricularly. Through the syringe-adapted-tip of the inner cannula, serum or drugs may be administered.
