PURPOSE: This study was intended to evaluate the positional relationship between the hyoid bone and the mandible in patients with mandibular protrusion after mandibular set-back surgery by means of 3D-CT. MATERIALS AND METHODS: Preoperative(3 weeks before) and postoperative (6 weeks after) 3D-CT and cephalogram were taken on 32 patients(12 male, 20 female, mean age of 23.2) treated by bilateral sagittal split osteotomy with rigid fixation. The angular measurement on 3D-CT basilar view were deviation of Me and H, long axis angle of left and right cornu majus. The lineal measurement on 3D-CT basilar view were composed of intercondylar line and coordinates(x,y) of Me and H. The angular and lineal measurement of lateral cephalogram were composed of mandibular plane angle, SNA, SNB, ANB, FH-NA and FH-NB, and coordinates(x,y) of B, Pog, Me and H, PAS, Lpw, MPH and IAS. On the frontal cephalogram, deviation of Me were evaluated. RESULTS: The mean mandibular set-back was 8.0mm horizontally and mandibular plane angle was slightly increased. The hyoid bone was displaced postero-inferiorly, the distance between MP(mandibular plane) and H(hyoid bone) was increased and the posterior airway space values (PAS, Lpw, IAS) were decreased. The coordinates Me(x,y), H(x,y) and deviation angle Me' and H'were revealed the strong positive correlation. CONCLUSION: The results revealed that the horizontal, vertical and transverse relationship of the mandibular and the hyoid bone movements were significantly correlated in patients performed mandibular set-back surgery.

Three-dimensional solid model has not been widely used in surgical prediction of orthognathic surgery because freque from occlusal restorations or prosthesis limited the usefulness of simulated surgery involving occlusion. We prepared three-dimensional(3D) solid model from CT data and integrated the 3D solid model with dental cast using a face-bow transfer technique combined with skeletal reference measurement and confirmation with cephalometric radiographs. With this simple and easy method, it was possible to predict bony interference between the proximal and distal segment of the mandible so that we can prevent condylar displacement after sagittal split ramus osteotomy of the mandible with prominent asymmetry. The method error was within 2mm and it seemed to be useful in preoperative planning for maxillofacial surgery with maxillo-mandibular occlusal change

We report a case of myiasis on the left submandibular area after radiation therapy for squamous cell carcinoma. A 77-year-old man visited our hospital, 7 weeks after complicating a course of radiation therapy, had a 7cm diameter necrotic ulcer on the left submandible. The margin of the lesion were undermined by numerous interlinking passages containing 20 maggots. The maggots were removed by simple extraction and were identified as Calliphoridae Lucilia. The probable origin of the myiasis in this case was attributed to poor environmental condition and general weakness of the patient. Oppotunistic cutaneous myiasis can be prevented by protecting open wounds from flies, wound should not be left without a covering capable of excluding flies, especially in the summer month.

OBJECTIVES: This study evaluated bisphosphonate-related osteonecrosis of the jaws (BRONJ) in patients diagnosed with malignant bone tumors. Demographic findings, laboratory, and radiographic analyses were performed to characterize disease severity and progression. MATERIALS AND METHODS: Patients who had been diagnosed with BRONJ (2005-2010) at the authors' hospital according to the American Association of Oral and Maxillofacial Surgeons were investigated. Twenty-one patients (12 with multiple myelomas, 7 with breast cancer, and 2 with prostate cancer) who had been treated with bisphosphonates (BPs) for malignant bone tumors were included. Radiographic evaluations with a panorama, computed tomography, whole body bone scan, and laboratory findings were evaluated for erythrocyte sedimentation rate (ESR), c-reactive proteins (CRPs), and c-terminal cross-linked telopeptides (CTXs). RESULTS: The average age of the patients was 64.3 (range 51-80), and they were treated with BPs for an average of 35+/-19 months before BRONJ was diagnosed. Types of BPs were zolendronic acid (81%, intravenous [IV]), pamidronate (4.8%, IV), zoledronic acid+pamidronate (4.8%, IV), alendronate (4.8%, per os [PO]), and ibadronate (4.75%, PO). Extraction (67%) and persistent irritation of dentures (20%) were the most common triggering factors. BRONJ in the mandible was reported in 62% of the cases, in the maxilla 24%, and both 14%. BRONJ occurred more frequently in patients with multiple myelomas (n=12, 57.1%). Most of the patients revealed an advanced BRONJ stage; Stage I (n=2, 9%), Stage II (n=13, 62%), and Stage III (n=6, 29%). CONCLUSION: The differences of the ESR, CRP, and CTX values between the BRONJ-recurring and non-recurring patients after the treatment were not evident. Later stage BRONJ patients showed lower CTX levels. A drug holiday after the diagnosis of BRONJ did not remarkably influence the surgical outcomes. However, the limited number of patients in the study should be considered.

To evaluate the stability after orthognathic surgery in cleft lip and palate patients using rigid fixation, 20 patients underwent primary repair in childhood and later developed a jaw deformity and malocclusion that required orthognathic surgery were reviewed. Two groups, one of 10 patients performed Le Fort I osteotomy with sagittal split ramus osteotomy and one of 10 patients with sagittal split ramus osteotomy of the mandible, were evaluated. Each group had unilateral cleft only and all alveolar cleft sites had been grafted with autogeneous bone before the orthognathic surgery. The amount of surgical movement and relapse were compared in both horizontal and vertical dimensions. Two-jaw surgery group was more stable than mandibular surgery only group in mandibular position (p< 0.05). Statistically significant relapse was observed in mandibular skeletal point in mandibular surgery group (p<0.05). There was no statistically significant relapse in the skeletal point of two-jaw surgery group. However, the correlation between the horizontal surgical movement and relapse was detected (r = 0.88). This correlation indicates the need of overcorrection. The presence of scar tissues and relatively deficient maxillary bone could be attributed to this close relation between the surgical change and relapse.
