Multicenter assessment of exclusive endoscopic endonasal approach for the treatment of 53 olfactory neuroblastomas.

Background: Given the particularities of olfactory neuroblastoma (ONB) and the lack of studies on the subject, a multicenter collaborative study was conducted to assess treatment strategy.

Methods: Fifty-three patients with ONB were included from the French Rare Head and Neck Cancer Expert Network (REFCOR) database: 16T1, 8T2, 19T3, and 10T4. All cases were treated endoscopically with skull base removal and repair in 26 cases (49%) and without external craniotomy.

Endovascular management of a carotid aneurysm into the sphenoid sinus presenting with epistaxis.

Non-traumatic cavernous internal carotid artery (ICA) aneurysms are rare, and favour the occurrence of massive recurrent epistaxis, which is associated with a high mortality rate. We report the case of a 67-year-old woman presenting a ruptured ICA aneurysm extending into the sphenoid sinus, revealed by epistaxis. Selective coil embolization of the aneurysm was performed.

Innovative endoscopic sino-nasal and anterior skull base robotics.

Purpose: Design a compact, ergonomic, and safe endoscope positioner dedicated to the sino-nasal tract, and the anterior and middle-stage skull base.

Methods: A motion and force analysis of the surgeon's movement was performed on cadaver heads to gather objective data for specification purposes. An experimental comparative study was then performed with three different kinematics, again on cadaver heads, in order to define the best architecture satisfying the motion and force requirements.

Robotic thyroid surgery: our experience with the infraclavicular approach.

Background: Robot-assisted endoscopic transaxillary thyroidectomy is an emerging surgical technique. Despite promising results it presents some limitations and remains controversial in terms of usefulness and validity. We developed an alternative robotic technique using a gasless infraclavicular approach.
