Pterional approach versus unilateral frontal approach on tuberculum sellae meningioma: Single centre experiences.
BACKGROUND
Tuberculum Sellae Meningioma is one of the most challenging surgeries among neurosurgeons. Many approaches have been established in the effort of removing the tumor and some of them are supported by an advanced neurosurgical technology. In this study, we aim to compare the efficacy of the two most common approaches, the pterional and the unilateral frontal.


METHODS
This was a restrospective study that aimed to observe the efficacy of the two most common approaches used in our center, the pterional and the unilateral frontal, in resecting the tuberculum sellae meningioma, which was held in Dr. Hasan Sadikin General Hospital, Bandung, from July 2007-July 2010. Twenty patients were enrolled with half of them operated by the pterional approach and the rest by unilateral frontal approach. We evaluated six parameters: tumor size, degree of tumor removal, surgery duration, post-operative cerebral edema, patients' outcome, and length of stay, which were evaluated to take measure of the efficacy of each procedure.


RESULTS
We found that the pterional approach gave more advantages than the unilateral frontal. Total tumor removal, especially in tumor size ≥ 3 cm was achieved in a greater number of subjects in the pterional (P<0.023). Other advantages of the pterional compared to the unilateral frontal were a shorter surgical duration (P=0.024), shorter length of stay (P=0.009) and less frequency of post-operative cerebral edema incidence (P=0.023).


CONCLUSIONS
According to our facilities and conditions, it seems that the pterional approach have more advantages than the unilateral frontal approach in tuberculum sellae meningioma surgery.
