To visualize the course of the tympanic segment of chorda tympani nerve (CTN) using ultra-high-resolution computed tomography. ⋯ The course of the tympanic segment of normal CTN was comprehensively visualized by ultra-high-resolution computed tomography. Preoperative evaluation of the tympanic segment of CTN might be helpful in avoiding iatrogenic injury during middle ear surgery.

To evaluate the prognostic value of the buffer coefficient, calculated as the ratio of the buffer volume (volume of intracranial cerebrospinal fluid) at the peak of brain edema to the baseline brain volume, and some other parameters in patients with massive cerebral infarction (MCI). ⋯ The buffer coefficient has potential benefits as a prognostic indicator for MCI that can be used to detect even subtle changes in brain edema.
-
To examine complication rates and radiographic outcomes in patients undergoing surgery for adult spinal deformity (ASD) by a junior surgeon. ⋯ Observed complication and revision rates in this cohort were consistent with rates reported in the literature. No preoperative patient risk factors significantly increased risk of complications or need for revision, suggesting that no patient population is at increased risk undergoing surgery by a junior surgeon. The relatively high rate of complications observed in this cohort may be a result of high baseline morbidity.
-
To assess the safety of foregoing invasive monitoring in a select group of patients undergoing awake craniotomy for supratentorial tumor resection. ⋯ Intraoperative physiologic control and surgical site complication avoidance do not warrant routine invasive blood pressure monitoring during awake craniotomy for tumor resection.

A 43-year-old man was admitted to the emergency department for motor vehicle collision. First clinical impression was traumatic injury of the right eye with bare light perception. A physical examination revealed multiple nodular skin lesions on the head and neck. ⋯ Mannitol was administered, and no neurosurgical intervention was needed for traumatic brain injury. Canthorrhaphy of the right eye was performed to preserve patient's right eyeball. At 1-month follow-up, patient's right eyeball was preserved, and vision improved as well.
