Background: The Endonasal Endoscopic Transsphenoidal Surgery (EETS) is a minimally invasive procedure to approach and remove pituitary tumors and other sellar lesions. The process causes less pain, faster recovery, and provides further minimal invasive access in critical cases. However, a slight deviation of tools from the target area can be fatal to the patients. The aim of this study is to design and develop a prototype robot to demonstrate neurosurgical robot-assisted EET approach.
Methods: The effectiveness of a prototype robot in executing a minimally invasive EET surgery was studied in 6 cadavers. The robot was associated with a multi-information integrated technique for surgery including QR code tracking. The robot was controlled and driven by the neurosurgeon.
Results: The standard procedure of EET was followed and the robot carried out the first stage of EET under the supervision of neurosurgeon. Finally, the sellar was reached by the neurosurgeon. The result was determined by qualitative analysis and was confirmed by the neurosurgeon. The time for the entire EET surgical procedure showed marked reduction compared to the traditional EET approach.
Conclusion: The robot design was found to be technically feasible and hence can be used for assisting the EET procedure. The robot used was able to assist the neurosurgeon correctly to approach the sinus.

Endoscopic Orbital Clearance/Debridement: A Potential Substitute for Orbital Exenteration in Rhino-orbital Mucormycosis.

Mucormycosis is an aggressive, lethal fungal infection affecting the nasal and paranasal territory in immunocompromised patients. Orbital involvement is not uncommon and may require orbital exenteration. The management of orbital involvement in invasive fungal sinusitis is challenging, ranging from conservative retrobulbar amphotericin B injection in the early stages to orbital exenteration in late stages.

The sphenoidal sinus septum is one of the most important landmarks during endonasal endoscopic transsphe-noidal operations. During routine coronal sectioning of the face, we found a variant Y-shaped septum in the sphenoidal sinus of a female cadaver. This unusual septum was found between two sections (anterior and posterior sections) and located inferior to the pituitary gland.

Background: Chronic rhinosinusitis (CRS) is traditionally classified into CRS with or without nasal polyps and more recently into eosinophilic and non-eosinophilic endotypes. Limited research exists on the relationship between CRS subtype and mucociliary function. This study compares ciliary beat frequency (CBF) across CRS subtypes.

Background: Epidermoid cyst (EC) located completely within the pituitary infundibulum is a rare entity with only seven reported cases. In this study, we have described our experience with resection of intra-infundibular epidermoid cysts (IECs) and reviewed the existing literature highlighting its distinguishing features and operative nuances.
Methods: Three consecutive cases of IEC operated at our institute was retrospectively studied.

Background: Endoscopic techniques allow for improved visualization and tumor debulking of pituitary adenomas. More thorough tumor resection, however, can be associated with higher rates of CSF leaks. We set out to determine if CSF leaks influenced patient perceived quality of life outcomes.
