Tympanotomy: exploratory "laparotomy" of the middle ear.

In some cases of conduction deafness or mixed deafness, direct inspection of the area believed to be involved is the only means by which diagnosis can be made with certainty. This can be done by a method of tympanotomy that is used for stapes mobilization. The necessary exposure is done with local anesthesia, is not painful, is well tolerated by the patient and requires only two days in hospital. Reparative procedures may be carried out as indicated.
