Dear Editor,

We thank Dr. Nagm et al. [4] for their interest in our article [3] and for the comments they expressed in the letter published on Acta Neurochirurgica, entitled: Endoscopic Transpalpebral Transorbital Anterior Petrosectomy: Does Safer Surgical Freedoms Necessitates Modifications” [4]. The authors communicated several interesting points that we would like to address one by one.

Dr. Nagm and colleagues [4] questioned about ideal surgical space with safer exposure and good maneuverability when performing anterior petrosectomy via the endoscopic superior eyelid transorbital approach.

The authors proposed to perform the lamina papyracea removal, via an endoscopic endonasal route, in order to potentially reduce the orbit compression while reaching the petrous apex via the transorbital pathway [4]. We think that this technical adjunct is a very clever idea aimed to moderate orbit compression during the transorbital approach. However, we need to highlight that anatomic lab is not...
