Correction of the protruding ear with a modified anterior scoring technique.
This article describes a modified anterior scoring technique to provide natural-looking results after correction of the protruding ear. The modified technique is described, and its advantages are compared with the conventional anterior scoring technique and with the other two basic techniques (Converse and Mustardé). ⋯ The conventional anterior scoring technique for otoplasty is one of the most useful and reliable techniques, applicable in all cases of prominent ears. However, in some cases, it is difficult to control the cartilage bending completely. By using three adjusting mattress sutures (4-0 vicryl) through the perichondrium on the posterior side, combined with shallower scoring incisions, it is possible to create symmetry with the opposite ear and prevent "telephone ear" complication.

A gross and microscopic study of cerebral injuries accompanying maxillofacial high-velocity projectile wounding in dogs.
This study investigated the pathologic characteristics and some related factors of cerebral damage associated with maxillofacial high-velocity missile wounds. ⋯ High-velocity projectile maxillofacial wounds can induce associated brain injury.

Comparative StudyGlycosaminoglycan components in temporomandibular joint synovial fluid as markers of joint pathology.
This study investigated the correlation between temporomandibular joint (TMJ) disease and the composition of glycosaminoglycans (GAGs) components in the synovial fluid (SF). ⋯ These results suggest that the delta di-6S:delta di-4S ratio in the synovial fluid of the TMJ reflects the proteoglycan metabolism of the joint tissues, particularly of the articular cartilage and synovial tissue. This ratio could be used to diagnose joint diseases and to predict articular cartilage destruction or synovial proliferation caused by these diseases.

Proteoglycans in the synovial fluid of the temporomandibular joint as an indicator of changes in cartilage metabolism during primary and secondary osteoarthritis.
The specific aim of this investigation was to assess differences between primary and secondary osteoarthritis (OA) of the temporomandibular joint (TMJ) using clinical evaluation and synovial fluid analysis for proteoglycans. ⋯ Secondary OA is a common disorder of the TMJ. However, there is no apparent difference in the metabolism of the joints with primary and secondary OA as assessed by proteoglycans in the synovial fluid. The apparent absence of the 3b3(-) epitope, in contrast to its presence in OA of other major synovial joints, suggests that there are some differences between the cartilage metabolism of the TMJ and these other joints during OA.
