Abstract:
Objective To summarized the experiences of endoscope used to cope with the tumor located at the dead angle during microsurgical treatment to increase the total removal rate of cholesteatoma in cerebellopontine angle (CPA). Methods We retrospectively analyzed the data of 34 patients with CPA. These patients underwent microsurgery from January 2007 to July 2009. All patients received CT and MRI on the head and brain, and were documented with cholesteatoma by surgery.Retrosigmoid approach was adopted; tumors and their capsules were separated and removed, and then the dead angles were inspected by 0-30 degree rigid neuroendoscopy to dissect the residual tumor. Another 36 patients with CAP, admitted to our hospital and performed surgery without neuroendoscopy from January 2004 to December 2006, were chosen as controls. Results Total removal was achieved in 31 patients (91.18%), and subtotal removal in 2 (5.88%). Temporal neurological damage was noted in 2 patients; no death was noted. All patients followed up for half a year to one and half a year returned to work and study. In control group, total removal was achieved in 25 patients (69.44%) and subtotal removal in 11 (30.56%); neural dysfunctions were present in 9 (25%); no patient died. Conclusion Endoscope-assisted microsurgery can decrease the tumor recurrence by exposing the remnant tumor in the death angle and increasing the total removal rate.
