This case reports a bilateral asymmetrical posterior extension of the frontal sinuses into the orbital roof with an unusual expansion into the roof of the optic canal in a 55-year-old male cadaver. The posterior extensions of the sinus were lined by mucoperiosteum and were separated from the underlying orbital contents and optic nerve by a thin plate of bone. This knowledge of an unusual anatomic variation of the frontal sinus may help understand better the ocular and intracranial complications associated with frontal sinus pathologies.
本病例报告了一名55岁男性尸体中，额窦双侧不对称向后延伸至眶顶，并异常扩展至视神经管顶的情况。鼻窦的向后延伸部分内衬有黏膜骨膜，与下方的眶内容物和视神经之间由一薄层骨板分隔。对额窦这种不寻常解剖变异的了解，可能有助于更好地理解与额窦病变相关的眼部和颅内并发症。
