Complications
In this study, there were 4 patients with recurrence and 3 patients with
recurrence. No complications related to facial nerve occurred in all
patients. Among 36 patients in the endoscopic technique group, a study
by Arindam et al. found that only one patient had residual lesions. In
another study, Marchioni et al. found that 0.4% of patients had bone
dislocation and 0.6% had persistent tympanic membrane perforation.9,10 Cochlear/auricle cartilage displacement and
subsequent retraction pocket formation are other important
complications. Minimization of other important complications can be
controlled by reducing excessive bone removal. Cholesteatoma can be
removed to ensure easier and more stable reconstruction when it extends
below the front buttress.
In our study, for similar diseases, the value of MESVI in the endoscopic
group was higher, which caused the bone defect to be lesser; therefore,
we concluded that it would result in fewer cartilage displacement and
retraction pocket formation. Because we followed up the patients for
only 1 year, there is no statistical difference between the two groups.
