Background:
Meckel's cave dermoid cyst is an extremely rare and a technically challenging lesion. The objective of the study is to show that endoscopic endonasal approach (EEA) has recently emerged as a better alternative to transcranial approach for this formidable tumor, owing to minimal retraction-related morbidity.
Method:
A 52-year-old male presented with numbness over the right side of the face and temporal area for the last 3 years. On examination, there was decreased sensation to touch, pain, and temperature over the right V1, V2, and V3 areas with an absent right corneal reflex. Imaging revealed a heterogenous extra-axial lesion in the right Meckel's cave. The tumor was resected by an extended endonasal transpterygoid approach.
Results:
The patient had improvement in his symptoms with no endocrine complication.
Conclusion:
This case demonstrates the surgical techniquenof endoscopic endonasal transpterygoid resection of a Meckel's cave dermoid cyst.
