Class I bimaxillary protrusion is characterized by proclined incisors, a convex facial profile, procumbent lips, and increased lip strain. Treatment includes the extraction of premolars and the mesial movement of the proclined anterior teeth in the extraction spaces to correct the inclination. This case report describes the treatment of an 18-year-old male patient who presented with class I bimaxillary protrusion and procumbent lips.

Background: Endoscopic endonasal techniques, initially developed for sinonasal tumor resection, have revolutionized the approach to orbital lesions. The emergence of endonasal orbital tumor surgery has prompted anatomical studies focusing on the medial orbit, yet there remains a lack of literature on maneuverability lateral to the optic nerve (ON), with current feasibility assessments relying primarily on the plane of resectability (POR).
Methods: Bilateral anatomical dissections were conducted on four latex-injected human cadaveric heads using an endoscopic medial and inferior orbitotomy and superomedial displacement of the inferior rectus muscle (IRM) to access the inferolateral intraconal quadrant.

Retractions serve a crucial role in maintaining the integrity and accuracy of scientific literature. There has been growing interest in understanding the patterns behind retractions. This bibliometric study analyzed retracted articles published between 2003 and 2022, indexed by the Science Citation Index Expanded of the Web of Science Core Collection database.

Background: Tear size and shape are known to prognosticate the efficacy of surgical rotator cuff (RC) repair however, current manual measurements on magnetic resonance images (MRI), exhibit high interobserver variabilities and exclude three-dimensional (3D) morphological information. This study aimed to develop algorithms for automatic 3D analyses of posterosuperior full-thickness RC tear to enable efficient and precise tear evaluation and 3D tear visualization.
Methods: - A deep-learning network for automatic segmentation of the tear region in coronal and sagittal multicenter MRI was trained with manually segmented (consensus of 3 experts) pd- and T2 weighted MRI of shoulders with full-thickness posterosuperior tears (n=200).
Objective: To compare the space closure, root resorption and canine angulation during en-masse retraction of the labial segment after extraction of first premolars with or without interseptal bone reduction distal to the maxillary canines.
Design: A single-centre, parallel randomised control trial included 16 participants with a mean age of 21.5 years.
