Background: A surgical and anatomic approach to the skull base using the transmaxillary route is presented. This route is well-known and used for a long time for sinus conditions.
Method: This study was performed on injected cadavers. This study describes step by step this approach in microsurgical conditions following a vital lead: the infraorbital nerve.
Results: Anatomical landmarks are located in order to avoid complications. These complications are on one hand, hemorrhages by vascular lesions and on the other, definitive nerve palsy.
Conclusion: Several skull base approaches exist, transfacial routes produce cosmetic damages. This route preserves the functional anatomy of the nose because it preserves the integrity of the lateral wall of the nasal cavity.

A rare morphological variant: Bilateral accessory optic canal.
Morphologie

Department of Anatomy, Faculty of Medicine-Pharmacy, University of Rouen-Normandy, Rouen, France.
The optic canal (OC) transmits the optic nerve (ON) and ophthalmic artery (OA) from the skull base to the orbit. Its morphological variability is narrow, and most commonly its dimensions are being studied. We observed an unexpected variant during a routine investigation of our osteological collection.

Different phylogenies describing the evolutionary relationships of Ornithopoda are mostly based on cranial features, however there is a lack of well-preserved and complete skulls for the basal member of the clade, hampering our knowledge on the mode and tempo of these herbivorous dinosaurs. Here we describe YLSNHM 01942, a well-preserved skull of a juvenile neornithischian from the Liaoning Province of China.

Postoperative facial nerve (FN) dysfunction is associated with a significant impact on the quality of life of patients and can result in psychological stress and disorders such as depression and social isolation. Preoperative prediction of FN outcomes can play a critical role in vestibular schwannomas (VSs) patient care. Several studies have developed machine learning (ML)-based models in predicting FN outcomes following resection of VS.

Government Medical College, Bhadradri, Kothagudem, Telangana, India.
Background: Taylor and Palmer introduced an angiosome (vascular) concept in reconstructive plastic surgery in 1987. The angiosome is considered a segment of a nerve (cranial or peripheral nerve) supplied by a primary source of blood vessels.
Purpose: To observe the arteries supplying the vestibulocochlear nerves (VIII) from the brainstem till their termination.
Markedly T2-Hypointense Clival Plasmacytoma With Light Chain Deposition Disease: A Case Report.

Department of Medical Imaging, University of Arizona College of Medicine - Tucson, Tucson, USA.
Plasmacytomas are rare monoclonal neoplastic plasma cell proliferations in soft tissue or bone, with clival plasmacytomas being extremely rare and occasionally presenting with light chain deposition disease (LCDD). While imaging findings for clival plasmacytomas have shown variable T2 signal characteristics, complete T2 signal loss has not been previously reported. We present a case of a 61-year-old female found to have a 1.
