The management of petroclival and foramen magnum meningiomas has been revolutionized by the techniques of cranial base surgery. However, these tumors are still among the most difficult cranial base lesions to treat. In this report, we discuss the classification, presenting symptoms, preoperative investigation, treatment indications, operative approaches and technique, postoperative complications and care, and results of surgery of petroclival and foramen magnum meningiomas. Careful analysis of tumor- and patient-related factors has helped us to predict which features can lead to postoperative problems in patients allowing surgeons to appropriately modify their behavior. The application of cranial base techniques-combined with new knowledge about the limitations of microsurgical resection-can greatly reduce postoperative morbidity in these patients.

Sheep Head Cadaveric Model for the Transmeatal Extensions of the Retrosigmoid Approach.
Asian J Neurosurg
December 2024
Department of Neurosurgery, Federal University of Sao Paulo, Sao Paulo, Brazil.
The transmeatal extension of the retrosigmoid approach is an important procedure used in the treatment of various pathologies affecting the posterior fossa, petroclival region, and jugular foramen. Mastering this technique requires a high level of manual skill, particularly in temporal bone drilling. The objective of this study was to describe an easily accessible and cost-effective model of the transmeatal extension of the retrosigmoid approach using cadaveric sheep heads.

To explore the surgical techniques and clinical outcomes of endoscopic transnasal approaches in the treatment of skull base chondrosarcomas. Data from patients diagnosed with skull base chondrosarcomas and treated via endoscopic transnasal surgery at the Department of Otorhinolaryngology and Head and Neck Surgery, Xuanwu Hospital, Capital Medical University, from 2013 to 2022 were collected. This retrospective study analyzed the patients' clinical presentations, histopathological grading, involved sites and extents, and complications following the endoscopic transnasal surgery.

Objectives: To analyze the overall long-term outcome of surgically treated skull base and temporal bone chondrosarcomas.
Methods: The medical records of patients with surgically treated skull base and temporal bone chondrosarcomas between 1983 and 2024 were thoroughly evaluated.
Results: Out of a total of over 5000 skull base surgeries performed at our center, only 29 patients had histopathologically confirmed chondrosarcomas of the skull base and temporal bone.
Comparison of endoscopic multiport approaches to the petrous apex: contralateral transmaxillary versus contralateral medial transorbital corridor.

Article Synopsis
- The study explores the challenges of accessing the petrous apex (PA) using endoscopic techniques, comparing two methods: the traditional endoscopic endonasal approach (EEA) combined with the contralateral transmaxillary (CTM) corridor and a proposed new method called the contralateral medial transorbital (cMTO) corridor.
- An anatomical analysis was conducted using 14 cadaveric specimens to dissect and assess each approach, focusing on metrics like working distance, angle of attack, and surgical freedom.
- Results indicated that the cMTO corridor offers a significantly shorter working distance to the PA compared to the CTM and EEA methods, with similar visual angles
Endoscopic Endonasal Approach to the Ventral Petroclival Fissure: Anatomical Findings and Surgical Techniques.
J Neurol Surg B Skull Base
August 2024
Department of Neurosurgery, Stanford Hospital, Stanford, California, United States.
The endoscopic endonasal approach has emerged as an excellent option for the treatment of lesions involving the petroclival fissure (PCF). Here, we investigate the surgical anatomy of the ventral PCF and its application in endoscopic endonasal surgery. Sixteen head specimens were used to investigate the anatomical features of PCF and relevant technical nuances in translacerum, extreme medial, and contralateral transmaxillary (CTM) approaches.
