Treatment: Other Procedures & Management
Endoscopic endonasal odontoidectomy
Endoscopic endonasal odontoidectomy removes the odontoid through the nose, a less invasive alternative route to relieve front-side brainstem compression.
In short: Endoscopic endonasal odontoidectomy
- It removes the odontoid through the nose (endonasal route).
- It uses an endoscope for visualization.
- It is an alternative to the transoral approach.
- It is used in selected complex Chiari cases, often with fusion.
What it is
Endoscopic endonasal odontoidectomy is a surgery to remove the odontoid through the nose (the endonasal route), using an endoscope for visualization. It is a less invasive alternative to the transoral (through-the-mouth) approach for relieving front-side brainstem compression in complex Chiari.
Understanding Endoscopic endonasal odontoidectomy
Like the transoral approach, this procedure addresses front-side (ventral) compression of the brainstem by removing the odontoid, but it reaches the odontoid through the nasal passages rather than the mouth. Using an endoscope (a thin camera) for visualization, the surgeon removes the compressing bone. The endonasal route can offer advantages in some cases — for example, potentially avoiding some of the issues associated with the transoral route (such as effects on the mouth and swallowing during recovery). As with the transoral approach, it is usually combined with craniocervical fusion for stability. This is a specialized procedure used in selected complex cases. Understanding endoscopic endonasal odontoidectomy clarifies a less invasive front-side approach for relieving brainstem compression in complex Chiari.
Why it matters
Understanding endoscopic endonasal odontoidectomy helps families see a less invasive alternative route — through the nose — for relieving front-side brainstem compression in complex Chiari, often combined with fusion.
