Hiatus for petrosal nerve
Hiatus for Petrosal Nerve
The Hiatus for Petrosal Nerve is a small opening in the temporal bone of the human skull that allows for the passage of the greater petrosal nerve.
Anatomy[edit | edit source]
The hiatus for the petrosal nerve is located in the petrous part of the temporal bone. It is situated near the carotid canal and the foramen lacerum. The greater petrosal nerve passes through this hiatus to reach the pterygopalatine ganglion.
Clinical Significance[edit | edit source]
Understanding the location and function of the hiatus for the petrosal nerve is important in neurosurgery and otolaryngology. Damage to the greater petrosal nerve during surgery can lead to a loss of lacrimation and salivation.
