  • Patients with facial paralysis, in whom nerve damage is irreparable or in whom the innervation of the paralyzed musculature cannot be restored by nerve suture, grafting, or cross-face nerve transplantation, should be offered some form of reconstructive static and dynamic aid. Temporalis muscle-fascia unit used as a circumorbital sling and motor unit is a dynamic controlled reconstructive procedure, but it has several disadvantages such as wide surgical exposure, bulky-looking at lateral canthal area, insufficient voluntary control. This is a case report of facial palsy of posttraumatic lagophthalmos of 41-year-old male, which was corrected by temporalis muscle-tendon transfer with plantaris tendon transplantation.

  • The incidence of arthritis in the ankle is relatively low compared to other joints. On the other hand, it receives a lot of pressure per unit area, is vulnerable to damage, and arthritis can arise after trauma. Early ankle arthritis can be considered a case of osteophyte subchondral sclerosis without narrowing of the joint space. Conservative treatment, such as weight control, insole use, drug use, and injection therapy for early ankle arthritis, is effective and can be considered before surgical treatment. Nevertheless, if pain is persistent, surgical treatment to remove bony spurs is effective. Ensuring that there is no other cause of pain when deciding whether to perform an operation is very important.

  • Purpose It has been stated that patient satisfaction is the crucial factor for determining success in plastic surgery. The convergence of medical science and computer vision has made easier to satisfy patients who wants to have plastic surgery. In this paper, we try to apply 3D face modeling in plastic surgical area. Materials and Methods The author introduces a method for accurate 3D face modeling techniques using a statistical model-based 3D face modeling approach in a mirror system. Results We could successfully obtain highly accurate 3D face shape results. Conclusion The method suggested could be used for acquiring 3D face models from 2D face image and the result obtained from this could be effectively used for plastic surgical areas.

  • When a small gear rotates at a very high speed over 40,000 rpm, frictional heat is generated on the gear surfaces. Thermal deformations and stresses arising from frictional heat may lower the efficiency and fatigue life of the high-speed gear. Especially, such frictional heat has much stronger effects on the performance of millimeter-sized high-speed gears used for surgical and dental hand-pieces, due to a small surface area. An analytical equation was derived to calculate frictional temperature on a mating gear surface and conduction heat transfer analysis was performed. Thermal deformation and contact stresses were then calculated using FEM for gears used for medical hand-pieces. The contact stresses of the meshed gear and pinion increase by 19.4% and 16.4%, respectively, when the frictional thermal deformations are considered.

  • Local anesthesia is administered to control pain, but it may induce fear and anxiety. Root planing is a non-surgical periodontal therapy; however, when it is performed in an extensive manner, some tissue removal is inevitable. Notably, this removal may be so painful that local anesthesia is required to be administered to the area scheduled for the treatment. Although patients tend to accept root planing easily, they frequently express a fear of local anesthesia. Intraosseous anesthesia (IA) is an intraosseous injection technique, whereby local anesthetic is injected into the cancellous bone supporting the teeth. A computer-controlled IA system (CIAS) exhibits multiple benefits, such as less painful anesthesia, reduced soft tissue numbness, and the provision of palatal or lingual, as well as buccal, anesthesia via single needle penetration. In this report, we present two cases of root planing that were performed under local anesthesia, using a CIAS.

  • Many congenital and acquired defects occur in the maxillofacial area. The buccal fat pad flap (BFP) is a simple and reliable flap for the treatment of many of these defects because of its rich blood supply and location, which is close to the location of various intraoral defects. In this article, we have reviewed BFP and the associated anatomical background, surgical techniques, and clinical applications. The surgical procedure is simple and has shown a high success rate in various clinical applications (approximately 90%), including the closure of oroantral fistula, correction of congenital defect, treatment of jaw bone necrosis, and reconstruction of tumor defects. The control of etiologic factors, size of defect, anatomical location of defect, and general condition of patient could influence the prognosis after grafting. In conclusion, BFP is a reliable flap that can be applied to various clinical situations.

  • Maxillary sinus floor augmentation (MSFA) is an essential procedure for implant installation in the posterior maxillary area with vertical alveolar bone deficiency. For the past several decades, MSFA has been refined in terms of surgical methods along with technical progress, accumulation of clinical studies, and development of graft materials and surgical instruments. Although some complications in MSFA are inevitable in clinical situations, management of those complications in MSFA has been well established thanks to many clinicians and researchers. Nevertheless, some rare complications may arise and can result in fatal results. Therefore, clinicians should be well aware of such rare situations and complications associated with MSFA. In this review, the authors present several rare complications regarding MSFA, along with corresponding management strategies through a thorough review of the literature.

  • Kimura's disease is a chronic inflammatory disease which often presents as a tumor like swelling in the head and neck region. This lesion is benign but it may easily be mistaken for a malignant tumor. Kimura's disease has been confused with angiolymphoid hyperplasia with eosinophilia(ALHE). The cause is unknown, but theories include autoimmune, allergic, neoplastic, and infectious cause by insect bites and parasites. The treatment of choice is surgical removal. Recently we experienced a case of Kimura's disease occuring in the both side of posterior neck triangle area of a 37 year old male patient who was treated with surgical excision and systemic corticosteroid administration.

  • More than 120 surgical methods for the correction of hallux valgus deformities have been reported. For the correction of moderate to severe hallux valgus deformities with aesthetic demands, minimally invasive surgery at the proximal area can be considered. This paper reports a case of moderate hallux valgus deformity treated by a minimally invasive proximal transverse metatarsal osteotomy followed by intramedullary plate fixation.
