Measurement of the Superior and Inferior Limit through the Pure Endoscopic Endonasal Trans-choanal Approach to the Craniovertebral Junction: Cadaveric Anatomical Study.

This article, published in the Journal of Neurological Surgery, discusses the measurement of the superior and inferior limits of the endoscopic endonasal approach (EEA) to the craniovertebral junction. The EEA is a minimally invasive method for decompressing this area, with lower morbidity rates compared to traditional approaches. The study aimed to measure these limits purely through the endonasal trans-choanal approach, without the use of septostomy. The results showed that the rhinopalatine line (RPL) predicted the inferior limit more accurately than other reference lines, making it feasible to perform surgery on conditions such as basilar invagination or lower clival lesions without damaging the septum or other nasal structures.
