Abstract:

Objective To compare the clinical results in terms of operative lesions among treatments via different approaches which include frontal transcortical(n=19), frontal intergyral(n=11), and frontal transcallosal(n=11) approaches respectively. Methods The removal extent of brain tissue, the removal degree of tumer and the incidence of postoperative morbility were analyzed with statistical method. Results No significant difference among the removal degree of lesions, but significant difference among the removal extent of brain tissue and the rate of postoperative morbility. The highest postoperative morbility rate occur with the patients operated via frontal transcortical approach (55.6%), but the lowest postoperative morbility rate occurs with the patients via frontal transcallosal approach (9.1%). The postoperative morbility rate of patients via frontal intergyral approach (18.2%) is less than that operated via frontal transcortial approach; but higher than that operated via frontal transcallosal approach. Conclusion Operational treatment of the septum pellucidum via transcallosal approach and intergyral approach accord with the microinvasive concept. It is appropriate to select transcallosal approach in frontal part as the first choice for septum pellucidum in terms of operative lesions.
