Coronoid process hyperplasia: an unusual cause of mandibular hypomobility [PDF]

Brazilian Dental Journal, 2012
A large number of disorders affecting the masticatory system can cause restriction of mouth opening. The most common conditions related to this problem are those involving the temporomandibular joint (TMJ) and the masticatory muscles, when facial pain also is an usual finding.

Minimally invasive surgery of hyperplasia of coronoid process of mandible: Endoscopically assisted intra oral coronoidectomy – Case report

Advances in Oral and Maxillofacial Surgery
Introduction: Coronoid process hyperplasia (CPH) is a rare developmental condition characterized by abnormal elongation of the coronoid process, resulting in progressive, painless limitation of mandibular opening due to mechanical impingement against the

Anatomical and Biomechanical Stability of Single/Double Screw‐Cancellous Bone Fixations of Regan–Morry Type III Ulnar Coronoid Fractures in Adults: CT Measurement and Finite Element Analysis

Orthopaedic Surgery, Volume 15, Issue 4, Page 1072-1084, April 2023., 2023
Biomechanics of 12 finite element (FE) models of fractured and surgical elbows were simulated. The pull‐out force and rotation torque of screw fixations were ranked by finite element model (FEM). Two new stability factors of screw fixations were determined by FEM sensitivity test.

Regulatory role of human fibrocartilage stem cells in condyle osteochondroma

Cell Proliferation, Volume 56, Issue 1, January 2023., 2023
This study reports that human fibrocartilage stem cells are the potential cell‐of‐origin of condylar osteochondroma. Activated PI3K/AKT signalling pathway regulates cell apoptosis of hFCSCs and further affects stem cell function, which leads to cartilage pathological disorder and hypertrophy.

Fgf8 dosage regulates jaw shape and symmetry through pharyngeal‐cardiac tissue relationships

Developmental Dynamics, Volume 251, Issue 10, Page 1711-1727, October 2022., 2022
Abstract Background Asymmetries in craniofacial anomalies are commonly observed. In the facial skeleton, the left side is more commonly and/or severely affected than the right. Such asymmetries complicate treatment options. Mechanisms underlying variation in disease severity between individuals as well as within individuals (asymmetries) are still ...

Temporomandibular joint ankylosis—“Knowing when not to operate”: Case report and qualitative systematic review of literature

Clinical Case Reports, Volume 10, Issue 3, March 2022., 2022
Fibrodysplasia ossificans progressive (FOP) is a rare cause of temporomandibular joint ankylosis (TMJA). Temporomandibular joint ankylosis in FOP is an absolute contraindication for surgery since surgery (including routine dental procedures) may lead to recurrence and exacerbation of the condition. Atraumatic dental treatment, preventive dentistry, and
