Is pre-operative Evaluation of Eustachian Tube Function Using a Modified Pressure Equilibration Test Predictive of Good Postoperative Hearing and Middle Ear Aeration in Type 1 Tympanoplasty Patients?
ET function measured with a modified pressure equilibration test using an inflation-deflation manometric method is a good indicator of an aerated middle ear and is predictive of improved postoperative hearing.
After adjustment for baseline differences, calcium channel blockers were associated with significantly reduced mortality after cardiac surgery. This benefit also extends to the subgroup that underwent coronary artery bypass grafting. A large randomized controlled trial of perioperative calcium channel blockers is therefore warranted.
