Department of Oral and Maxillofacial Surgery, the First Affiliated Hospital of Bengbu Medical University, Bengbu Anhui, 233004, P. R. China.
Objective: To investigate the effectiveness of posterior lateral perforator flap in lower limb combined with free fibula for maxillary tissue defect repair.
Methods: Between December 2018 and December 2023, 16 patients with the maxillary malignant tumors were admitted. There were 10 males and 6 females, with an average age of 64.
Orbital and Ocular Venous Congestion: A Rare Manifestation of Hypervascular Paget Disease of the Bone.

Department of Ophthalmology, Massachusetts Eye and Ear, Harvard Medical School, Boston, Massachusetts.
A 73-year-old male with a history of incidentally diagnosed Paget disease of bone affecting the skull and left orbit 2 years prior presented with 3 months of vision loss, proptosis, and periorbital swelling of the OS. Examination showed best-corrected Snellen visual acuity of 20/150 in the affected eye, intact motility, 7 mm of relative proptosis, significant dilated and tortuous "corkscrew" conjunctival vessels, serous choroidal and retinal detachments, optic nerve hyperemia, and venous tortuosity and dilation. Although the bony lesions in the left orbit were stable from 1 year prior on imaging, the diagnostic angiogram demonstrated osseous blush and hypervascularity of the lesion.

Objective: This study aimed to predict long-term growth-related changes in skeletal and dental relationships within the craniofacial complex using machine learning (ML) models.
Materials And Methods: Cephalometric radiographs from 301 subjects, taken at pre-pubertal (T1, age 11) and post-pubertal stages (T2, age 18), were analysed. Three ML models-Lasso regression, Random Forest, and Support Vector Regression (SVR)-were trained on a subset of 240 subjects, while 61 subjects were used for testing.

December 2024
Department of Surgical Oncology, Division of Head and Neck Surgery, National Cancer Institute, Cairo University, Cairo, Egypt.
Background: The submental artery island flap (SIF) is a valid option for palatal reconstruction. However, the main limitation for its application for palatal defects is the arc of rotation. A novel modification for tunneling of the antegrade design of SIF that allows a compliant easy reach to the defect is described.
