Combined Access Closed Tympanomastoidectomy: Microsurgery Allied to

Status Active, not recruiting

Clinical Trial Summary

Chronic otitis media is a prevalent medical condition, leading to important impact in the lives of the individuals with this condition, and a great amount of patients may need surgical intervention. The main objectives of the surgery in these cases are to restore the anatomy of the middle ear, to improve hearing and to remove the infection to avoid further complications. Still, chronic otitis media with cholesteatoma presents high rates of recurrence and residual symptoms after surgery.

The standard technique used for treatment of chronic otitis media is microsurgery. Nonetheless, with the development of new technologies that use endoscopy, it is now possible to use endoscopic surgery to improve the visualization of the cholesteatoma and ear structures by combining both techniques.

This study will evaluate the efficacy of the combined access surgery technique, which is microsurgery combined with endoscopy, for closed tympanomastoidectomy in patients with cholesteatoma. Furthermore, the study aims to compare the results of the combined access technique and the standard technique by randomizing the patients in two groups: one group will receive tympanomastoidectomy by standard technique and the other group will receive combined technique.

Clinical Trial Description

Patients with cholesteatoma and medical indication of closed tympanomastoidectomy will be randomized into two groups. In the first group, microsurgical tympanomastoidectomy will be performed; while combined technique will be performed in the other group. The combined technique improves the visualization of the middle ear canal and the mastoid. Herewith, the best visualization of the surgical site facilitates the full removal of the cholesteatoma. In addition to that, the combined technique is less invasive than the standard one, since less bone debridement is required to access the surgical site.

The outcomes of the study will be evaluated through follow up medical appointments and exams. The patients will be followed by monthly medical appointments with otoscopic evaluations for diagnose of possible recurrence of the disease or residual cholesteatoma. Also, audiometry exams will be performed in the third, sixth and twelfth months. Image exams such as nuclear magnetic resonance may be performed at the end of this period to evaluate relapse of the disease if the otoscopic evaluation is inconclusive. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
