제안 방법
- The patients visited our clinic at 3 months, 6 months, and 12 months after surgery. All patients included in the study had clinical photographs and computed tomography (CT) studies at 12 months postoperatively.
- Grade 3 (severe hollowing) was used if the difference was more than 50% (Table 1). Patient satisfaction was assessed by the subjective assessment of temporal hollowing, which was evaluated on visual analogue scale (VAS) from 0 (no deformity) to 10 (severe temporal hollowing) at 12 months postoperatively.
- The 12-month postoperative CT imaging was used to evaluate the degree of temporal hollowing. To quantify the severity of temporal hollowing, we measured the distance of depression at the level of temporal fossa from the coronal CT image.
- The collected demographic information included patient age, sex, body mass index, and past medical/surgical histories. Intraoperative details, including the size of bony defect, the size of craniotomy bone segment, the size and thickness of calvarial onlay graft, and tumor pathology were documented.
- And, the other limitation of the study was a small sample size. The goal of this study was to complement these limitations by introducing a method of covering the temporal bony defect by using an autologous calvarial bone graft and, at the same time, augmenting the temporal fossa with a separate autologous bone graft. In addition, we present the outcomes between patients who underwent this procedure compared to those who did not.
- Radiologic studies were reviewed, and preoperative and postoperative photographs were analyzed for the subjective assessment of temporal hollowing. The patients visited our clinic at 3 months, 6 months, and 12 months after surgery. All patients included in the study had clinical photographs and computed tomography (CT) studies at 12 months postoperatively.
- One patient had prolapse of fixed temporalis muscle which was corrected by bihalving and refixation of the temporalis muscle. The second patient had hypertrophy of temporal fat pad, which was corrected by partial excision of the excessive fat tissue. No patients had infections or seroma accumulations (Table 6).
- We set the grade of temporal hollowing from 0 to 3: the difference less than 10% between the temporal thickness of operated side and non-operated side was designated to grade 0 (no hollowing); the difference of 10%–25% was designated to grade 1 (mild hollowing); the difference of 25%–50% was designated to grade 2 (moderate hollowing).
대상 데이터
- Surgical technique of temporal augmentation with calvarial onlay graft. A 48-year-old male with glioma on right temporal lobe underwent pterional craniotomy with temporal augmentation with calvarial onlay graft. (A)The cranial bone flap was separated.
- Patients who underwent pterional craniotomy at the time of intracranial tumor excision at the Bundang Jesaeng General Hospital from January 1, 2015 to December 31, 2016 were included in this retrospective study. Patients who had recurrence of the brain tumor, those who had preoperational temporal hollowing, or patients with less than 1-year follow-up were excluded from the study.
- Eighteen patients were excluded due to recurrence of the brain tumor (n=5) and insufficient follow-up period (n=13). Total 100 patients (38 males and 62 females) were included in this study. Forty-one patients underwent pterional craniotomy with temporal augmentation and 59 patients underwent pterional craniotomy without temporal augmentation.
데이터처리
- Continuous data between group 1 and group 2 were compared using two-sample t-tests or MannWhitney tests depending on the assumption of normality. Categorical variables were analyzed using chi-square tests. A p-value<0.
