OBJECTIVE To assess changes in hyoid, tongue, pharyngeal airway, and head posture in patients who had mandibular setback surgery by intraoral vertical ramus osteotomy (IVRO) and to investigate the influence of LeFort I osteotomy. MATERIALS AND METHODS Sixty patients with skeletal Class III malocclusion were evaluated. All patients had mandibular setback(More)
We report a case of oral stings by spermatophores of the squid Todarodes pacificus . A 63-yr-old Korean woman experienced severe pain in her oral cavity immediately after eating a portion of parboiled squid along with its internal organs. She did not swallow the portion, but spat it out immediately. She complained of a pricking and foreign-body sensation in(More)
OBJECTIVE The purpose of this study was to determine the features of synovial fluid, the shape of the disk, and the presence of disk displacement without reduction (DDsR) of the temporomandibular joint. STUDY DESIGN A total of 612 bilateral temporomandibular magnetic resonance images of 306 patients were reviewed. The status of the joint was categorized(More)
Synovial chondromatosis is a benign disease that rarely affects the temporomandibular joint (TMJ). It can be seen commonly in the superior joint space and presents with various signs and symptoms according to the stage of progression. Sometimes it presents as a large swelling in the preauricular area with or without cranial extension, and the clinical and(More)
OBJECTIVE To evaluate the volume and position of the temporomandibular joint structures, specifically the glenoid fossa and the condylar head, in patients with facial asymmetry. STUDY DESIGN Fifty-six adult patients were divided into two groups-asymmetry group and control group-based on the severity of the mandibular asymmetry, as seen on their(More)
Alloplastic total replacement of the temporomandibular joint (TMJ) was developed in recent decades. In some conditions, previous studies suggested the rationale behind alloplastic TMJ replacement rather than reconstruction with autogenous grafts. Currently, three prosthetic products are available and approved by the US Food and Drug Administration. Among(More)
This case report describes the successful treatment of an adult patient with skeletal Class II open-bite malocclusion secondary to idiopathic condylar resorption. Total alloplastic joint reconstruction and counterclockwise rotation of the maxillomandibular complex combined with orthodontic treatment provided a satisfying outcome with maximum functional and(More)
J Korean Assoc Oral Maxillofac Surg 2012;38:284-94) Objectives: The anterior open bite with temporomandibular disorders (TMD) is one of the most challenging cases both orthodontically and surgically. We introduce an intermaxillary traction treatment for patients with anterior open bite and TMD using a skeletal anchorage system (SAS). Materials and Methods:(More)
Though growth factors allow tissue regeneration, the trade-off between their effectiveness and adverse effects limits clinical application. The key issues in current growth factor therapy largely derive from initial burst pharmacokinetics, rapid clearance, and proteolytic cleavage resulting in clinical ineffectiveness and diverse complications. While a(More)
This case report describes the successful treatment of severely impacted mandibular second molars with severe apical root resorption of the mandibular first molars. The vertically impacted second molars were orthodontically moved (using orthodontic mini-implants) without additional root resorption of the first molars. The orthodontic treatment provided a(More)
