Response to Letter to The Editor "Transcanal Transpromontorial Approach to Vestibular Schwannoma: Are We There Yet?"

6. The cerebrospinal fluid leak rates (7.4%) in what the authors call conservative or minimally invasive surgery are about 10 times more than the incidence of the same (0.85%) in our published series of 1,865 patients of which over 41% of the tumors were large tumors (> 20 mm) in the cerebellopontine angle. 7. The authors compare their facial nerve (FN) results with our series of VS removed via translabyrinthine approach and conclude that their postoperative FN results of House-Brackmann I and II were 95.9% in comparison with ours which was 59.87%. This comparison is unscientific and rather imprudent as the authors fail to draw to the attention of the readers the fact that in our large series of 1,865 patients, 1,542 (88.5%) of the tumors were grade I (extrameatal) tumors, and 561 (32.2%) of them were grade III to V tumors (> 20 mm in the cerebellopontine angle) (6). A meaningful comparison would be when the postoperative FN outcomes 200 of our patients in whom the tumor was intrameatal (grade 0) were to be compared with the authors series of intrameatal tumors. Here, it turns out that that our FN results (House-Brackmann I & II) after translabyrinthine approach in 200 intrameatal tumors turn out to be 92.5% which is comparable to the authors’ results of 95.9% in 49 patients. 8. Finally, the duration of follow-up of the current series is 14 months (the authors have included a follow-up of even 2 mo) which is too short a period to determine definitive postoperative results.
