Study of the Diagnostic Accuracy Between the Position of the Articular Disc According to Magnetic Resonance Imaging and Arthroscopy Findings for Temporomandibular Disorders.

The aim of this study was to prospectively evaluate the diagnostic accuracy between the position of the disc in the temporomandibular joint (TMJ) according to findings on magnetic resonance (MRI) imaging and the position of the disc depending on the "roofing" in arthroscopic evaluation in patients who underwent arthroscopy for a temporomandibular disorder (TMD). This relationship was analyzed in 298 patients diagnosed with internal derangements. The concordance between the 2 methods was evaluated using the κ coefficient.

Consensus Report and Recommendations on the Management of Late-stage Internal Derangement of the Temporomandibular Joint.

This report investigates late-stage internal derangement (ID) of the temporomandibular joint (TMJ) with the aim of establishing a more effective and personalized treatment protocol to improve patients' quality of life (QoL). A consensus was reached among maxillofacial surgeons specializing in LSID, based on a literature research and collective expert experience following the Delphi method. Consensus was considered to be achieved when a response received at least 80% of votes.

Endoscopically Assisted Intraoral Coronoidectomy for Treatment of Coronoid Hyperplasia.

Hyperplasia of the coronoid process of the mandible is a rare condition defined as an abnormal and progressive elongation of the coronoid process (unilateral or bilateral). Jacob disease is the name given to a pseudo-joint formation between the coronoid process and the zygomatic bone. The main clinical finding is a progressive, painless difficulty in opening the mouth, due to contact of the coronoid process with the posterior surface of the zygomatic bone or the medial surface of the zygomatic arch.

Temporomandibular Joint Arthroscopic Surgical Techniques: Electrocoagulation and Myotomy Indications.

Temporomandibular joint (TMJ) surgical arthroscopy has become a usual operation to treat different pathologies such as internal derangements and degenerative joint diseases and osteoarthritis. Although many instruments such as palpators, forceps, scissors, scrapers, scalpels, and motorized terminals are needed to perform different arthroscopic surgical procedures, it is of paramount importance to have devices that allow the surgeon to cut and coagulate tissues safely. Coblation (cold ablation) is a process that using a radiofrequency electrical energy passing through saline solution and produces plasma that can be applied precisely to tissues to break molecular bonds within cells.

Surgical Ciliated Cysts in Orthognathic Surgery.

Surgical ciliated cysts (SCC) are rare entities that were first described in the Japanese literature after treatment for chronic maxillary sinusitis. Classically associated with surgery to the maxillary sinus, they have also been reported in association with orthognathic surgery, bone grafting, and trauma. These lesions can develop from a few months up to several years after the surgical procedure.

Management of a Penetrating Orbital Trauma from an Unusual Foreign Body with Associated Eye Injury.

The aim of this article is to describe the principles that should guide the management of an orbital trauma with ocular injury through an updated review of the literature and the study of a clinical case involving an 80-year-old woman who presented with a penetrating orbital wound due to a wooden foreign body with a closed ocular trauma. Satisfactory and stable results over time are determined by systematically analyzing and evaluating each aspect of the case following a surgical strategy based on the most current protocols.

Comparison of intra-articular injection of plasma rich in growth factors versus hyaluronic acid following arthroscopy in the treatment of temporomandibular dysfunction: A randomised prospective study.

Purpose: The main objective of our study was to evaluate the effectiveness of the injection of plasma rich in platelet-derived growth factors (PRGF) versus hyaluronic acid (HA) following arthroscopic surgery in patients diagnosed with internal derangement of the temporomandibular joint (TMJ) with osteoarthritis (OA).

Materials And Methods: A total of 100 patients were randomised into two study groups. Group A (n = 50) received an injection of PRGF, and Group B (n = 50) received an injection of HA.

Treatment of bilateral hyperplasia of the coronoid process of the mandible. Presentation of a case and review of the literature.

Bilateral hyperplasia of the coronoid process is infrequent. It consists of an elongation of the coronoid process of the mandible and is, accordingly, a mechanical problem, limiting mouth opening. This article looks at the case of a 28 year-old male with significant limitation on opening his mouth, secondary to bilateral hyperplasia of the coronoid process.

Surgical treatment of benign parapharyngeal space tumours. Presentation of two clinical cases and revision of the literature.

Parapharyngeal space (PPS) tumours, most of them benign, account for some 0.5% of tumours of the head and neck. The importance of these tumours lies mainly in two aspects: on the one hand, the difficulty of early diagnosis, due to the lack of symptoms in the initial stages and, on the other, the extreme complications of performing surgery in the parapharyngeal region.

Sporadic oral angiomyolipoma. Case report.

Angiomyolipoma (AML) is a rare, benign tumour composed of a variable proportion of lipocytes, smooth muscle and thick-walled blood vessels. AML is part of a family of tumours arising from perivascular epithelioid cells (PEComas), and many cases are associated with tuberous sclerosis, with the kidney being the most frequent site involved. We report a case of sporadic AML in the hard palate of a 52-year-old male, an extremely unusual location for this tumour.
