Ventilation of the middle ear cleft is essential for successful tympanoplastic surgery. In patients with tympanic membrane perforations, the preoperative evaluation of eustachian tubal function may be useful in identifying those subjects with nonfunctioning or blocked eustachian tubes. Additionally, the anatomic localization and identification of the structural abnormalities affecting tubal function may permit specific corrective therapy to be undertaken. The proposed approach for clinically evaluating eustachian tubal function combines the gross micro otoscopic examination of the middle ear mucosa, the evaluation of the eustachian tube's ability to equilibrate induced middle ear pressures and, in selected cases, the radiographic visualization of the eustachian tubes. Using these parameters, a systematic approach was designed which is useful in preoperatively evaluating the eustachian tube in patients with tympanic membrane perforations who are being considered for middle ear reconstructive surgery.
