Final answer:
A transsphenoidal approach is a surgical craniotomy approach used in cases of craniosynostosis, brain tumors, and other instances where biopsy is not feasible. It involves accessing the surgical site through the sphenoid bone, providing a minimally invasive option for surgery.
Step-by-step explanation:
A transsphenoidal approach is a type of surgical craniotomy approach used in cases of craniosynostosis, brain tumors, and other instances where biopsy is not feasible.
This approach involves accessing the surgical site through the sphenoid bone, which is located at the base of the skull.
Overall, a transsphenoidal approach allows surgeons to perform minimally invasive surgeries with less disruption to surrounding brain structures.
