Complications of Chronic Suppurative Otitis Media AA Type-3 Years Experience at TUTH

Abstract

This retrospective study was carried out in the Department of ORL and Head &
Neck Surgery, Tribhuvan University Teaching Hospital, Maharajgunj, Kathmandu.
Three hundred patients having atticoantral type of chronic suppurative otitis media
underwent emergency or routine mastoid exploration from 14 April 1997 to 12
April 2000. Of the 300 patients, 64 (21.33%) had complications. Age of the patients
with complications ranged from 5-38 years. Thirty eight (59.38%) patients were male
while 26 (40.62%) were female. Forty eight (75%) had extracranial and 15 (23.44%)
had intracranial complications while 1 (2.08%) had both extra and intracranial
complications. Cholesteatoma was present in 233 (77.66%) patients and of these 48
(20.60%) had complications. Sixty seven (22.33%) patients had granulation tissue, of
these 16 (23.88%) had complications.In cholesteatomatous cases 34 (70.83%) had
extracranial complications. Intracranial complications were present in 14(29.17%)
cholesteatomatous cases. In patients with granulation tissue extracranial complication
was present in 14 (87.50%) patients and only one patient had intracranial
complication.Combination of extra and intracranial complications were found in 1
patient with granulation tissue. When compared with types of pathology extracranial
complications were higher in patients with granulation tissue (87.50% vs 70.83%)
and intracranial complications were found more in cholesteatomatous cases (29.17%
vs 6.26%). Both these findings were , however, statistically not significant. Reasons
behind these findings may be presence of granulation tissue beneath the epithelium
of choleateatoma, and association of both types of pathology with infection and
inflammatory process.
