This article discusses the use of intraoperative ultrasound (IUS) as an adjunct to the endoscopic endonasal approach (EEA) for the surgical resection of skull base lesions. The authors present a case study where a novel small-probe IUS was used to assist in the resection of a recurrent Rathke's cleft cyst (RCC) located in an atypical retrosellar region. The small-probe IUS provided real-time imaging feedback and enhanced visualization, allowing for accurate localization of the cyst and surrounding neurovascular structures. The authors conclude that IUS is a promising surgical adjunct that can potentially increase the extent of resection and decrease operation times. [Extracted from the article]

This article compares two surgical approaches, the endoscopic endonasal approach (EEA) and the midline suboccipital subtonsillar approach (STA), for accessing the jugular tubercle (JT) in the treatment of JT meningiomas. The study conducted on human cadaveric specimens measured three morphological variables: angle of attack (AoA), surgical freedom, and angle of endoscopic exposure (AoEE). The results showed that while STA offered greater surgical freedom, EEA provided superior visualization and AoEE. The choice of surgical approach should also consider the position of the lower cranial nerves in relation to the lesion. [Extracted from the article]

This article compares two different approaches for accessing the petrous apex through endoscopic endonasal surgery. The traditional approach, called the sublabial contralateral transmaxillary (CTM) corridor, has limitations such as instrument interference and increased nasal morbidity. The study introduces a new approach, the precaruncular contralateral medial transorbital (cMTO) corridor, which offers advantages such as a shorter distance to the target, a wider visualization angle, and better maneuverability for surgical instruments. The study was conducted on cadaveric specimens and further clinical studies are needed to validate these findings in patients. [Extracted from the article]
