Spontaneous intrauterine depressed skull fractures (IDSFs) are rare fractures that often require neurosurgical evaluation and therapy. Most of the reported congenital depressions are secondary to maternal abdominal trauma or instrumentation during delivery. Spontaneous IDSFs occur in the setting of uneventful normal spontaneous vaginal delivery or cesarean section, without obvious predisposing risk factors. The etiology and optimal management of spontaneous IDSFs remain controversial. ⋯ Neurosurgery consultation is necessary for initial evaluation of spontaneous IDSF. Surgical intervention is indicated for larger defects and/or intracranial involvement. Expectant management and negative-pressure elevation have also been shown to be effective.

Complications of the internal carotid artery (ICA) in surgery are rare but severe. This study aimed to locate the ICA with 5 stationary bony structures in the sellar region: the anterior clinoid process, the tuberculum sellae, the bottom of the hypophyseal fossa, the posterior edge of the hypophyseal fossa, and the postclinoid process and to do measurements to determine their anatomic relationship with the ICA. ⋯ The 3D coordinate system used in this study is of value in preoperational assessment, and data we obtained indicate the safety ranges avoiding damage to the ICA in surgery.
