Endonasal surgery is a minimally invasive approach for the removal of pituitary tumors (sarcomas). In this type of procedure, the surgeon has to complete the surgical maneuvers for sarcoma resection with extreme precision, as there are many vital structures in this area. Therefore, the use of robots for this type of intervention could increase the success of the intervention by providing accurate movements. Research has focused on the development of teleoperated robots to handle a surgical instrument, including the use of virtual fixtures to delimit the working area. This paper aims to go a step further with a platform that includes a teleoperated robot and an autonomous robot dedicated to secondary tasks. In this way, the aim is to reduce the surgeon's workload so that he can concentrate on his main task. Thus, the article focuses on the description and implementation of a navigator that coordinates both robots via a force/position control. Finally, both the navigation and control scheme were validated by in-vitro tests.

Unlabelled: Intracranial complications in inflammatory diseases of the ear and nose are currently not frequent, but their lethality remains high. The choice of optimal, safe and effective access in surgical treatment of purulent-inflammatory intracranial complications remains a subject of discussions and is based on an individual approach, depends on the volume, localization and clinical condition of the patient.
Objective: To demonstrate a clinical case of successful drainage of the brain frontal lobe abscess using endoscopic transnasal access under the control of the navigation system.
Evaluating the quality and readability of ChatGPT-generated patient-facing medical information in rhinology.

Purpose: The artificial intelligence (AI) chatbot ChatGPT has become a major tool for generating responses in healthcare. This study assessed ChatGPT's ability to generate French preoperative patient-facing medical information (PFI) in rhinology at a comparable level to material provided by an academic source, the French Society of Otorhinolaryngology (Société Française d'Otorhinolaryngologie et Chirurgie Cervico-Faciale, SFORL).
Methods: ChatGPT and SFORL French preoperative PFI in rhinology were compared by analyzing responses to 16 questions regarding common rhinology procedures: ethmoidectomy, sphenoidotomy, septoplasty, and endonasal dacryocystorhinostomy.

Rapid diagnosis of cerebrospinal fluid (CSF) leaks is critical as endoscopic endonasal skull base surgery gains global prominence. Current clinical methods such as endoscopic examination with and without intrathecal injection of fluorescent dye are invasive and rely on subjective judgment by physicians, highlighting the clinical need for label-free point-of-care (POC). However, a viable solution remains undeveloped due to the molecular complexity of CSF rhinorrhea mixed with nasal discharge and the scarcity of specific biomarkers, delaying sensor development.
