Background: The diagnosis and treatment of diseases at and around the sphenoid bone demands throughout understanding of its anatomy in 3-dimensional (3-D) space. However, despite the complex anatomic nature of the sphenoid bone, the current educational resources for its 3-D anatomy are insufficient for fast and long-term retention of the anatomic relationships.
Objective: To provide a simplified 3-D model of the sphenoid bone that anyone can easily learn and recall as an internal mental model.
Methods: Various studies on the anatomy of the sphenoid bone were analyzed. The collected data included the shape, foramina, canals, fissures, and minute details of the sphenoid bone. The gained detailed knowledge was subsequently used to create a 3-D model of the sphenoid bone with the help of 3-D computer software. A live lecture was given with this same software and simultaneously recorded with a microphone and a computer-screen recorder. A novel approach in lecturing, building the sphenoid bone from the scratch in a piecemeal fashion, was utilized.
Results: The sphenoid bone was recreated as an horizontally elongated box without a superior and posterior wall. All its foramina, canals, and fissures are visually easy to follow. Understanding its neuroanatomic terminologies based on their anatomic nature and relationships is enhanced.
Conclusions: This simplified 3-D model, along with the video lecture, will enhance the efficiency of studying sphenoid bone anatomy. The educational resources of this study can be obtained by medical students, radiologists, neurologists, neurosurgeons, neuroscientists, or anyone else seeking for fundamental understanding of sphenoid bone anatomy.

The Coexistence of Carotico-Clinoid Foramen and Interclinoidal Osseous Bridge: An Anatomo-Radiological Study With Surgical Implications.

Rhoton Neurosurgery and Otolaryngology Surgical Anatomy Program, Mayo Clinic, Rochester , Minnesota , USA.
Background And Objectives: The coexistence of complete carotico-clinoid bridge (CCB), an ossification between the anterior (ACP) and the middle clinoid (MCP), and an interclinoidal osseous bridge (ICB), between the ACP and the posterior clinoid (PCP), represents an uncommonly reported anatomic variant. If not adequately recognized, osseous bridges may complicate open or endoscopic surgery, along with the pneumatization of the ACP, especially when performing anterior or middle clinoidectomies.
Methods: According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews guidelines, a systematic scoping review was conducted up to June 5, 2023.
Cranial Base Changes After Trans-sutural Distraction Osteogenesis in Growing Patients With Cleft Lip/Palate and Midface Hypoplasia.
J Craniofac Surg

Department of Plastic Surgery, Peking University Third Hospital, Beijing, China.
Background: Transesutural distraction osteogenesis (TSDO) is a method of correcting midfacial hypoplasia (MH) secondary to cleft lip and palate (CLP) without osteotomy. However, there has been little research on how the morphology of the cranial base changes postoperatively or whether any correction of the cranial base occurs.
Materials And Methods: This retrospective study included 35 pediatric patients with MH secondary to CLP, who underwent TSDO treatment.
A Rare Pediatric Giant Cell Tumor of the Clivus Bone, H3.3 p.Gly35Trp-mutated: Case Report and Mini-review of the Literature.

Introduction: Giant cell tumor of bone (GCTB) is a rare, typically benign neoplasm that primarily affects long bones in adults, with clival involvement being extremely rare, particularly in pediatric cases: a mini-review shows a total of 28 described cases, of which only 5 were truly pediatric (within 14 years of age). Surgery is the treatment of choice, and Denosumab is reported to be the most effective drug therapy. To date, the GCTB's molecular hallmark is the somatic mutation p.

Gardner syndrome is characterized by multiple intestinal polyps and extraintestinal lesions. We describe FDG PET/CT findings of the extraintestinal lesions in a patient with Gardner syndrome. FDG PET/CT showed 2 hypermetabolic desmoid tumors in the abdominal wall, sclerotic areas with multifocal activity in the maxilla and mandible, multiple osteomas in the bilateral parietal, left frontal, sphenoid and ethmoid bones, an impacted tooth in the right maxilla, and bone islands in the T2 and T5 vertebral bodies.

The lateral pterygoid muscle (LPM), a critical component of the masticatory muscles, typically comprises upper (SLPM) and lower (ILPM) heads. However, it is essential to note that the LPM's structure is not a constant feature, as the number of bundles and their topography can vary. Moreover, additional heads, such as medial and middle heads, and unique-headed configurations of the LPM have been reported.
