Transnasal endoscopic orbital surgery is advancing, enabling tumor excision in the medial orbit. This minimally invasive approach offers enhanced visualization and access for selected orbital lesions.
Area of Science:
- Neurosurgery
- Ophthalmology
- Otolaryngology
Background:
- The field of orbital surgery has evolved significantly over the past two decades.
- Surgical interventions have expanded beyond orbital decompression to include the excision of tumors located in the medial orbit.
- Advancements in surgical instrumentation have influenced the types, locations, and sizes of tumors amenable to excision.
Purpose of the Study:
- To discuss key surgical considerations for approaching orbital lesions using the transnasal endoscopic technique.
- To review existing literature on transnasal endoscopic orbital surgery.
Main Methods:
- Literature review of transnasal endoscopic orbital surgery.
- Discussion of surgical considerations for accessing orbital lesions via an endoscopic endonasal route.
Main Results:
- The endonasal approach provides a surgical corridor to the orbit.
- This technique potentially offers improved exposure, illumination, and magnification for specific orbital lesions, particularly those in medial and apical locations.
Conclusions:
- The transnasal endoscopic approach can be a valuable technique for orbital tumor excision.
- It may serve as a primary or supplementary surgical method in carefully selected cases.
