Almost any form of chronic suppurative otitis media (CSOM) can be surgically treated.
The aim of the sudy is to determine the advantages of using computer navigation in the surgical treatment of patients with CSOM.
Patients and Methods: 25 patients with CSOM were treated with the use of computer navigation in 2015—2017 in the otorhinolaryngology department of Clinical Medical Center of A. I. Yevdokimov Moscow State University of Medicine and Dentistry. All patients were treated by an open middle ear surgery with tympanoplasty or without it depending on the prevalence of the process.
Results: in all cases, navigation contributed to surgery, displaying residual affected air cells. It was especially useful when we worked with the cavities of previously operated mastoids. During our operations, the system assured a complete dissection of the mastoid cells affected by the pathological process, including the tegmental and synodural cells. In addition, this allowed us, when finding a labyrinth fistula and dural exposure, to remove the found plastic defect at once, avoiding damage to surrounding structures. There were no serious complications during the operations.
Conclusions: in our opinion, the greatest advantages of using computer navigation in CSOM surgery are: more careful removal of pathological contents, greater safety during complex manipulations, especially with the altered normal anatomy of the middle ear, a reduction in the number of complications due to avoidance of traumas of neurovascular structures, lower blood loss, lower costs due to a decrease in the number of complications and length of stay in a hospital, a decrease in the number of relapses and the need for repeated operations, and also improvement of functional results.

Key words: chronic suppurative otitis media, CSOM, computer navigation, navigation support, attic disease, epimesotympanitis, tympanoplasty.
