How I do it: Optic nerve decompression in patient with osteopetrosis

Area of Science:

• Neurosurgery
• Ophthalmology
• Genetics

Background:

• Osteopetrosis is a rare genetic disorder characterized by excessive bone density, particularly affecting the skull base.
• This condition frequently results in optic canal stenosis, leading to optic nerve compression, atrophy, and potential vision loss.
• Prompt surgical intervention for optic nerve decompression is crucial for vision preservation.

Purpose of the Study:

• To describe a surgical technique for optic nerve decompression in osteopetrosis patients.
• To highlight the importance of precise surgical methods in managing vision loss associated with skull base abnormalities.

Main Methods:

• A pterional approach was employed, incorporating both extra- and intradural optic nerve decompression.
• Intradural identification of the optic nerve was utilized to ensure safe and adequate decompression, especially around the hypertrophic anterior clinoid process.

Main Results:

• The described pterional approach facilitated effective optic nerve decompression in the context of osteopetrosis.
• Intradural optic nerve identification proved to be a safe and valuable step in managing the complex anatomy.

Conclusions:

• Precise surgical techniques and thorough anatomical knowledge are paramount for successful optic nerve decompression in osteopetrosis.
• These factors are critical for minimizing surgical complications and promoting patient recovery and vision preservation.
