In this study, we adopted the term of supraorbltal and m.dialfrontal incisura or foramen as well as major incisura. We observed 190 cases (118 males. 72females) or unearted modern Chinese adult crania in Xi'an region, and obtained 6 types. Their incisurae were round more than foramina, and the difference of side and sex was analysed. The frequencies or the supraorbital and medial frontal incisura or foramen, and the Percentage of the ratiobetween the number of foramina and incisurae were compared respectively with those of population inother regions. For the first time, the percentage which was also termed supraorbltal and medialfrontal foramen-incisura index was put forwaed. It is or a better statistical value for race and population studies.展开更多

Methods: This study was retrospectively conducted on twenty four patients, age ranging from 20 to 65 years old, with anterior cranial fossa lesions who were meeting the eligibility criteria for eyebrow craniotomy in the period from August 2019 to January 2023. These patients were operated through eyebrow supraorbital approach in which microscopic endoscopic assisted technique were used. Extent of resection, clinical and cosmetic outcomes and complication incidence were assessed. Results: We included the twenty four patients who met inclusion criteria (17 females and 7 males) their ages ranged from 20 to 65 years. The most common pathology was meningioma in 19 patients. Two patients experienced supraorbital loss of sensation and only one patient experienced palsy of frontalis branch of facial nerve. Frontal sinus was breached in 3 patients with no patient experienced postoperative CSF leak. Total excision was accomplished for 23 patients. Four patients who had preoperative visual compromise, improvement of visual acuity and field defects was observed in 3 patients. No major intraoperative complications occurred. All patients filled cosmetic satisfaction questionnaire during their outpatient visits. For the eyebrow supraorbital approach, no incision related intolerable pain, no craniotomy defects or irregularities, no cosmetic complaints nor limitation of jaw opening were reported, and only minor symptoms in the form of limited eyebrow elevation, swelling and numbness in the forehead. Conclusions: The eyebrow craniotomy could be used safely as a more cosmetic and minimally invasive approach for a variety of anterior cranial fossa lesions. Endoscopic assistance has been found very useful for deeply seated lesions and hidden residuals with minimal brain retraction which couldn’t be accessed easily through microscopic field solely. Endoscopic assisted eyebrow supraorbital keyhole approach could be performed on a wider scale with great results but requires good selection of cases and more practice to expertise the needed skills.展开更多

The classic surgical approaches are the Pterional approach and the Lateral Supraorbital (LSO) approach, but there are shortcomings. Methods:This study retrospectively analyzed clinical and imaging data from 181 patients with MCA aneurysm clipping in the Department of Neurosurgery, First Affiliated Hospital of Soochow University between 2011 and 2017. Statistical analysis using parametric and nonparametric tests showed that P values below 0.05 were considered statistically significant. Results: The preoperative GCS score (P=0.003), Hunt-Hess scale (P < 0.001) and the operating habits of the surgeon (P < 0.001) affected the surgeon to choose a surgical approach. The choice of two surgical methods on the operation time (P < 0.001), skin incision (P < 0.001), complications (P=0.026), tracheotomy (P=0.014), prognosis (P=0.002) were significantly different. Different surgical approaches (P=0.002), Hunt-Hess scale (P <0.001), GCS scale (P < 0.001), GCS sorse (P < 0.001), skin incision (P=0.031) and complications (P < 0.001) are closely related to the prognosis of patients. Conclusions: Modified LSO approach provides another surgical approach for MCA aneurysm clipping, while avoiding the drawbacks of the LSO approach in the clipping of MCA distal aneurysm.展开更多

The purpose of this study was to describe and evaluate the results of surgical treatment of lesions in the anterior fossa and sellar region via a supraorbital keyhole approach using eyebrow incisions. Methods Between April 1994 and July 2003, 54 patients with lesions in the anterior fossa and sellar region were operated on via the supraorbital keyhole approach. The surgical results were studied retrospectively and compared with that of patients with lesions at the same locations but treated via a conventional subfrontal approach.Results No significant difference in curative effect was found between the conventional subfrontal approach and the supraorbital keyhole approach. However, the supraorbital approach required a much smaller skin incision, causing less surgical trauma, while achieving excellent surgical exposure and good recovery. Conclusion The supraorbital keyhole approach using an eyebrow incision is safe, effective, and both suitable and convenient for treating lesions in the anterior fossa and sellar region, with almost no adverse consequences on the facial features of patients.展开更多

At present, a variety of surgical approaches are used for tumor resection. We have conducted a comparative analysis of the two approaches most used in our department. Methods: The study retrospectively analyzed the clinical data from 65 patients with craniopharyngioma surgically treated by the two approaches mentioned above. Among these patients, 24 were treated by lateral supraorbital (LSO) approach and 41 by standard pterional approach. Indicators including, but not limited to, length of incision, operation time, postoperative pituitary function, urine volume, visual function improvement, and hospitalization were used to compare these two groups of patients. Results: The data shows that there was no significant difference in total tumor resection rate (P=0.54), postoperative visual field improvement (P=0.68) and postoperative function of endocrine. However, the LSO approach significantly reduced the operative incision (P=0.001), shortened the operation time (P=0.001) and operative complexity, while reducing the incidence of postoperative complications (P=0.04). Conclusions: In surgical treatment of craniopharyngioma, LSO approach has similar surgical effect with standard pterional approach, but it can significantly shorten the operation time, reduce surgical trauma and the incidence of complications. Therefore, LSO provides another alternative to surgical approach for microsurgical removal of craniopharyngioma.展开更多
