Background: The occipital artery (OA) is an important donor artery for intracranial and extracranial bypass surgery, but its path is tortuous, making it difficult to harvest. Part of the traditional intermuscular OA is not covered by muscle and is easily damaged during surgery. Currently, there are few reports on how to protect this segment of the OA.

Objectives: To assess the use of occipital vessels for microvascular anastomosis in head and neck free tissue transfer reconstruction.
Methods: A literature search was undertaken to identify studies utilizing the occipital vessels for microvascular anastomosis in free tissue transfer. Following literature review, 30 anatomic cadaveric dissections on 15 fresh unfixed cadavers were performed to evaluate the occipital artery and identify a reliable vein within reasonable proximity.
Lower Cranial Nerves in the Neck: An Anatomical Study.

Objectives The aim of this anatomical study was to analyze distances and anatomical relations between the lower cranial nerves and important neck landmarks. Methods Anatomical study based on neck dissection in Thiel-embalmed cadavers. Anatomical relations and distances between the vagus (X), accessory (XI), and hypoglossal (XII) nerves and important neck landmarks were registered and compared.

The current paper describes the creation of a simultaneous trimodal neuroimaging protocol. The authors detail their methodological design for a subsequent large-scale study, demonstrate the ability to obtain the expected physiologically induced responses across cerebrovascular domains, and describe the pitfalls experienced when developing this approach. Approach: Electroencephalography (EEG), functional near-infrared spectroscopy (fNIRS), and transcranial Doppler ultrasound (TCD) were combined to provide an assessment of neuronal activity, microvascular oxygenation, and upstream artery velocity, respectively.
