Summary
The posterior petrosal approach evolved from early otolaryngology techniques. Modern variations enhance surgical exposure and hearing preservation for complex neurosurgical procedures.
Area of Science:
- Neurosurgery
- Otolaryngology
- Surgical Anatomy
Background:
- Early retrolabyrinthine lateral petrosectomy offered limited surgical exposure.
- Limitations included the tentorium superiorly and sigmoid sinus posteriorly.
- Historical approaches often involved complete labyrinthectomy.
