Accurate location of the skin incision is helpful to decrease the technical difficulty and save the operative time in anterior cervical spine surgery. Spine surgeons usually use the traditional neck anatomic structures (the hyoid bone, thyroid cartilage, and cricoid cartilage) as landmarks during the surgery. However, the reliability of these landmarks has not been validated in actual practice. ⋯ The angle of mandible was found to be the most accurate landmark for identifying the cervical level, which corresponded to C2 and C2-C3 disc space. The hyoid bone, thyroid cartilage, and cricoid cartilage were not reliable to predict the cervical levels.

Both ossification of the yellow ligament (OYL) and the ossification of the posterior longitudinal ligament are relatively rare clinical entities. We report a extremely rare case of the spinal canal stenosis because of OYL, OPLL and listhesis at the cervicothoracic junction. ⋯ Triple factors of OYL, OPLL and listhesis contributed the cervical canal stenosis limited at cervicothoracic junction. Early diagnosis and surgical therapy is recommended for the good prognosis of this pathologic condition, as well as careful long-term follow-up for the early detection of its recurrence.

A 30-year-old man was admitted for sudden loss of consciousness. On angio-CT, a ring-like vascular formation arising from the anterior communicating artery with a low-density center was visualized. This finding was consistent with a giant arterial aneurysm presenting with a central thrombus, also called "donut aneurysm".

Transoral penetrating injury from a blunt-tipped chopstick is unusual and should be promptly dealt with because it is associated with high morbidity and mortality. ⋯ Preoperative and postoperative imaging and extensive monitoring of the patient's condition are mandatory for evaluation of possible development of complications. An optimal result can be obtained by a tailored management and treatment approach for each specific patient.

Case Reports
Spontaneous Resolution of Cerebral Pial Arteriovenous Fistula following Angiography: Report of two cases.
Cerebral pial arteriovenous fistula (AVF) is a rare disorder, and its natural course is uncertain. The present article reports 2 rare cases of pial AVF that underwent spontaneous cure after diagnostic cerebral angiogram. ⋯ It is possible that pial AVF is a cause of headache and neurologic symptoms in association with focal hyperperfusion. Diagnostic cerebral angiography should be performed to make a definite diagnosis; after this, pial AVF sometimes disappears.
