Correction to: Preservation of olfaction in anterior midline skull base meningiomas: a comprehensive approach

Clinical considerations for open versus endoscopic approaches in skull base surgery

PURPOSE OF REVIEW

We aim to distill the current body of evidence to consider when selecting an endoscopic versus open approach to address cranial base disease. We evaluate the evolution of modern surgical techniques and their respective limitations.

RECENT FINDINGS

Greater understanding of the role of tumor biology in relation to patient outcomes has led to increasingly sophisticated treatment algorithms. This combined with further development of advanced instrumentation and technique has led to the adoption of new surgical corridors previously unapproachable via traditional surgery.

SUMMARY

Endoscopic and open craniofacial approaches both remain important surgical techniques in the management of cranial base tumors. The modern skull base surgeon may employ a combination of approaches to optimize tumor extirpation while preserving functional outcomes. Patient history, anatomic tumor extent, histology, and functional goals should be considered thoroughly when planning any surgical intervention.

Modern endoscopic skull base neurosurgery

INTRODUCTION

Since the early use of the endoscopic view for treating simple intrasellar pituitary adenomas, the skull base surgery has experienced an unprecedented revolution elevating the treatment of skull base lesions to the next level in proficiency and excellence of care.

METHODS

We have reviewed the preclinical and clinical evidence supporting the use of the endoscope in the treatment of skull base lesions. In this article, we aim to discuss and provide a wide view of the current indications and future perspectives of the endoscopic endonasal approaches (EEA) and of the endoscopic transcranial approaches.

RESULTS

As in the development of any other technique, EEA have gone through a transformation process from theoretical anatomic models to a pragmatic clinical use. Along the way, EEA have required several modifications, as well as pushbacks in the application of this technique in some indications. This process has resulted in the provision of an additional tool to the current surgical armamentarium that allows the skull base surgeon to face most challenging lesions along the skull base.

CONCLUSIONS

The judicious combination of transcranial and endoscopic-transnasal approaches warrants highest chances of achieving satisfactory tumors resection with a reduced risk of complications.
