ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the efficacy of the surgery with lateral supraorbital approach for clipping anterior circulation aneurysms.</p><p><b>METHODS</b>The clinical data of 99 patients with anterior circulation aneurysms who underwent a clipping via lateral supraorbital approach from October 2012 to September 2014 and 75 patients, who underwent a clipping via pterional approach from January 2010 to December 2011 in the second Affiliated Hospital, Zhejiang University School of Medicine were reviewed. The operative duration, prognosis, residual rate and rupture rate during surgery were compared between two groups.</p><p><b>RESULTS</b>The patients by lateral supraorbital approach had a shorter operative duration, namely 37~61 min less than that in the patients by pterional approach. No difference were found in residual rate and rupture rate between two groups. The Glasgow Outcome Scale (GOS) at 3 months after surgery showed no significant difference between two groups.</p><p><b>CONCLUSION</b>The lateral supraorbital approach can be used safely and effectively with shorter operative duration and less tissue damage for treatment of patients with anterior circulation aneurysms.</p>
