Red ear syndrome: Perspectives for the otolaryngologist.

Ear Nose Throat J 2018 Dec;97(12):E11-E14

Department of Otolaryngology, Lenox Hill Hospital/Northwell Health, 110-11 72nd Ave., Suite 1B, Forest Hills, NY 11375, USA.

Red ear syndrome (RES) is an unusual, often unrecognized condition that has rarely been reported in the otolaryngology literature despite the presence of symptoms and associated disorders of relevance to the otolaryngologist. When present, RES may have diagnostic value when uncertainties arise in cases of sinus headache and referred otalgia. Despite the appearance of a distinctive red ear, as well as symptoms and associated disorders relating to otolaryngology, discussion of RES is generally limited to neurology-based publications.

Considerations for translation of tissue engineered fibrocartilage from bench to bedside.

J Biomech Eng 2018 Dec 5. Epub 2018 Dec 5.

ASME Fellow, Distinguished Professor, Department of Biomedical Engineering, University of California, Irvine, Irvine, CA 92697.

Fibrocartilage is found in the knee meniscus, the temporomandibular joint (TMJ) disc, the pubic symphysis, the annulus fibrosus of intervertebral disc, tendons, and ligaments. These tissues are notoriously difficult to repair due to their avascularity, and limited clinical repair and replacement options exist. Tissue engineering has been proposed as a route to repair and replace fibrocartilages. Read More

Prevention of Injury-Induced Osteoarthritis in Rodent Temporomandibular Joint by Targeting Chondrocyte CaSR.

J Bone Miner Res 2018 Nov 29. Epub 2018 Nov 29.

State Key Laboratory of Military Stomatology, Department of Oral Anatomy and Physiology and TMD, School of Stomatology, the Fourth Military Medical University, 145 Changle West Road, Xi'an, China.

Traumatic joint injuries produce osteoarthritic cartilage manifesting accelerated chondrocyte terminal differentiation and matrix degradation via unknown cellular and molecular mechanisms. Here we report the ability of biomechanical stress to increase expression of the calcium-sensing receptor (CaSR), a pivotal driver of chondrocyte terminal differentiation, in cultured chondrogenic cells subjected to fluid flow shear stress (FFSS) and in chondrocytes of rodent temporomandibular joint (TMJ) cartilage subjected to unilateral anterior cross-bite (UAC). In cultured ATDC5 cells or TMJ chondrocytes, FFSS induced Ca -loading and CaSR localization in endoplasmic reticulum (ER), casually accelerating cell differentiation that could be abrogated by emptying ER Ca stores or CaSR knockdown.

Department of Ophthalmology, Otorhinolaryngology and Head and Neck Surgery School of Medicine of Ribeirão Preto, University of São Paulo - USP, Avenida Bandeirantes, 3900, Ribeirão Preto, SP, 14049-900, Brazil.

Objectives: To investigate whether chronic temporomandibular disorder (TMD) patients showed any changes in swallowing compared to a control group. Moreover, it was examined whether swallowing variables and a valid clinic measure of orofacial myofunctional status were associated.

Material And Methods: Twenty-three patients with chronic TMD, diagnosed with disc displacement with reduction (DDR) and pain, according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), and 27 healthy volunteers (control group) were compared. Read More

Oropharyngeal adenoid cystic carcinoma invading the mandibular bone through the mandibular foramen.

Oral Radiol 2018 Nov 15. Epub 2018 Nov 15.

Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, 2-5-1 Shikata-cho, Kita-ku, Okayama, 700-8558, Japan.

Adenoid cystic carcinoma (ACC) is a rare epithelial tumor of the head and neck region, and one of the most common malignant tumors of the salivary glands. ACC is a slow-growing tumor characterized by perineural invasion and often has a high-recurrence rate. We describe a case of oropharyngeal ACC invading the mandibular bone through the mandibular foramen that showed a rare pattern of origin and invasion. Read More

Evaluating the mandibular condyles of patients with osteoarthritis for bone marrow abnormalities using magnetic resonance T2 mapping.

Oral Radiol 2018 Oct 30. Epub 2018 Oct 30.

Department of Oral and Maxillofacial Surgery, Tokyo Dental College, 1-2-2 Masago, Mihama-ku, Chiba, 261-8502, Japan.

Objectives: This study investigated whether erosion and osteophyte correlates with condyle bone marrow abnormalities (BMA), as detected with quantitative T2 mapping.

Methods: Fifty-six joints (in 44 patients) that demonstrated evidence of bony erosion (ER) or osteophytes (OS) related to disc displacement without reduction were studied with MR images. A control group of 50 joints (in 50 patients) was included. Read More

Ultrasonographic evaluation of masseter muscle thickness in patients with disk displacement with reduction.

Oral Radiol 2018 Aug 29. Epub 2018 Aug 29.

Department of Oral and Maxillofacial Surgery, Faculty Of Dentistry, Karabuk University, Balıklar Kayası Street, 78050, Karabuk, Turkey.

Objectives: This study was performed to ultrasonographically assess the masseter muscle thicknesses of individuals with disk displacement with reduction.

Methods: The thickness of the masseter muscle in 100 patients (28 male, 72 female; average age 34 years) who presented with one-sided temporomandibular joint pain and a clicking sound and were diagnosed with disk displacement with reduction was measured in relaxation and at maximum contraction using ultrasonography.

Results: In the contracted position, the difference in the masseter muscle thickness between the healthy side and the side with disk displacement with reduction was statistically significant (p < 0. Read More

Incidental findings during head and neck MRI screening in 1717 patients with temporomandibular disorders.

Oral Radiol 2018 Apr 3. Epub 2018 Apr 3.

Department of Oral and Maxillofacial Surgery, Tokyo Dental College, 1-2-2 Masago, Mihama-ku, Chiba, 261-8502, Japan.

Objective: Magnetic resonance imaging (MRI) plays an important role in the evaluation of temporomandibular disorders (TMDs). At our institution, we perform additional head and neck screening using head coils when performing MRI screening of the temporomandibular joint (TMJ) to detect lesions in areas other than the TMJ (lesions discovered by chance, or incidental findings; IFs) and to conduct a diagnosis of exclusion. The objective of this study was to determine the number and frequency of IFs detected during head and neck screening, according to sites and diseases. Read More

Trabecular structural changes in the mandibular condyle caused by degenerative osteoarthritis: a comparative study by cone-beam computed tomography imaging.

Oral Radiol 2018 Mar 26. Epub 2018 Mar 26.

Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Karadeniz Technical University, Farabi Street No. 64, Ortahisar/Trabzon, 61080, Turkey.

Objectives: Temporomandibular osteoarthritis causes pain and loss of function. In advanced cases, it may also result in destruction of joint cartilage surfaces and bone structure.

Methods: This study was performed to examine the potential changes in the condylar trabecular bone structure in patients with temporomandibular osteoarthritis. Read More
