Expanded Endonasal Surgery
The Expanded Endonasal Approach (EEA) is an innovative type of minimally invasive brain surgery that allows surgeon to access the skull base and upper cervical spine to remove brain tumors and other lesions through nose and sinuses. It is a standard of care for accessing a wide variety of hard-to-reach tumors and other skull base lesions (as large as softballs) without disturbing the face or skull.
Indications for EEA
The Expanded Endonasal Approach can be performed in following brain and spine conditions:
Brain tumors like:
Olfactory neuroblastomas
Cancers of the sinus like
Squamous cell
Sphenoid sinus carcinomas
Adenocystic
Meningiomas of the skull base
Pituitary tumors like
Pituitary adenomas
Acromegaly
Prolactinoma
Pituitary apoplexy
Olfactory neuroblastomas
Rathke’s cleft cysts
Skull base tumors and cysts
Chordoma and chondrosarcomas
Orbital tumors and Graves’ disease
MEEA Procedure
The approach uses the nose and sinuses as natural corridors to access tumors and lesions in critical areas at the base of the skull or top of the spine (cervical). The procedure is performed using a specially designed endoscope that provides light and a lens for viewing and transmitting internal images. The surgeon enters the skull base through nose. The tumor is removed using highly crafted instruments, high-definition optics and an endoscope. Finally, the skull base is reconstructed to seal off the brain from the nose.
Benefits of EEA
Skull base tumors can be accessed without the complications of open skull base surgery
Detailed, high-resolution view of the operating field
Neurosurgeon can perform precise movements using the microsurgical instrument
No need of face incisions and brain retraction
No visible scar
Fewer side effects
Less hospitalization (only 1 to 2 days)
Shorter recovery time
Less pain during and after surgery
Less disruption of critical nerves
Decreased morbidity
