Surgical Management and Outcomes of Cavernous Sinus Hemangiomas: A Single-Institution Series of 47 Patients

Abstract

The purpose of this study was to analyze the outcomes of cavernous sinus hemangiomas (CSHs) treated surgically, and to investigate factors that affect the gross total resection (GTR), newly developed or deteriorated cranial nerve injury (NDDCNI), and follow-up neurologic performance, and to further discuss the optimal treatment for CSHs. Clinical data of 47 patients with CSHs treated surgically at our institution between 2012-2018 were retrospectively reviewed. GTR was achieved in 26 (55.3%) patients. Significant relations were identified between the invasion of the sella turcica (odds ratio [OR]= 0.012; 95% confidence interval [CI], 0.001-0.213; P= 0.002), skull base ward (OR= 27.838; 95% CI, 2.995-258.748; P= 0.003), and GTR. The preoperative Karnofsky Performance Scale (KPS) score (OR= 2.966, per 10 score increase; 95% CI, 1.136-7.743; P= 0.026) and the invasion of the sella turcica (OR=7.137; 95% CI, 1.282-39.726; P= 0.025) were factors that significantly affected the incidence of NDDCNI. The average follow-up KPS score, which increased significantly compared with the pre (P < 0.001) and postoperative KPS scores (P < 0.001), was 89.1. Increased tumor size (OR= 0.044, per 1cm increase; 95% CI, 0.004-0.477; P= 0.010) was a risk factor for unfavorable follow-up KPS score. Being treated by an experienced skull base surgeon favors the total removal of CSHs, whereas the invasion of the sella turcica does just the opposite. Increased tumor size is a risk factor for unfavorable follow-up KPS score. The invasion of the sella turcica was related to NDDCNI and unfavorable follow-up KPS score.
