Purpose: This study was performed to survey the incidence and imaging characteristics of the antral exostoses in a Korean population. Materials and methods: The cone-beam computed tomographic images of 5,268 patients were reviewed for the presence of antral exostoses. Incidence, location, shape, structure and dimension were evaluated. Gender and side difference were analyzed by chi-squared test. Results: Ninety eight antral exostoses were found in 78 (1.5%) out of 5,268 patients. Gender and sides showed no statistically significant differences. Antral exostoses was often found in the lateral wall and floor of the maxillary sinus, accounting for 58.2% and 38.8% of the exostoses, respectively. Most exostoses had broad base and were composed of spongy bone surrounded by compact bone. The mean dimension was 9.1(W)*4.9(D)*5.3(H) mm. Conclusion: Antral exostoses is not uncommon in a Korean population. The identification of antral exostoses is clinically significant to avoid unnecessary examination and treatment. It also needs to be examined carefully in the implant planning or sinus lift procedure.

Bony exostosis, one of the osseous deformities, could act as a contributing factor of periodontal disease since it makes proper tooth brushing difficult and causes traumatic ulcer. The purpose of this case report is to show improvement of periodontal health by removal of bony exostoses and creation of physiologic osseous form. A 58 year-old female patient with recurrent ulcer and pain on bony exostoses located on left maxillary palatal area and both mandibular buccal areas was treated. Exostoses were removed and physiologically positive osseous form was created following vertical grooving, radicular blending, flattening interproximal bone and gradualizing marginal bone. The patient showed no further recurring traumatic ulcer and bone exposure. Moreover, periodontal pocket was eliminated and food impaction was decreased. In conclusion, periodontal health could be achieved through removal of multiple bony exostoses and development of ideal osseous form.

A black kite (Milvus migrans) was referred to the Gyeongnam Wild Animal Rescue Center, Jinju, Korea, with a clinical history of lethargy. On physical examination, three hard, variable sized, round shaped masses were found in the carpal and digit region of the right wing. On plain radiographs, three various sized, round to oval shaped, bony opacity masses with smooth margin were identified on the major digit, alular digit, carpometacarpus. The bird was euthanized due to poor prognosis. A full necropsy was performed, and the histopathologic findings in the bird were consistent with multiple exostoses.

Purpose: This study was aimed to analyze the incidence and the anatomical distributions of HME (Hereditary Multiple Exostoses) on upper limbs and its related change in alignment of the upper limbs in HME patients. Materials and Methods: Thirty eight patients who had been diagnosed HME between 2001 and 2009, were categorized into two groups; (1) group A (1-2 involvements); (2) group B (${\geq}$3 involvements). We checked the carrying angle, VAS (Visual Analogue Scale), limitations in daily activities, cosmetic satisfaction according to the number of exostoses invasion. Results: Among the 38 patients, 23 patients (43 cases) had exostoses in the upper limbs. The locations of exostoses in the upper limbs were proximal humerus in 33 cases (30%), distal ulna in 31 cases (28.2%), and distal radius in 24 cases (21.8%). The carrying angle of group A and B was $10.7^{\circ}$, $13.8^{\circ}$, VAS was 1.3, 3.5, and the limitations in daily activities was 7.3, 6.6 of 8 points. The cosmetic satisfactory cases were 13 and 10 cases, respectively. Conclusion: The deformity in upper limbs was observed in 65% of the HME patients. As the number of invasion increases, carrying angle and VAS were increased but limitations in daily activities and cosmetic satisfaction were decreased.

Osteochondroma is a common bone tumor but a rare tumor in the rib. It is often asymptomatic and observed incidentally. This is a case report of a 49-year-old woman with an osteochondroma mimicking a mediastinal mass in hereditary multiple exostoses. The chest X-ray and computed tomography (CT) scans revealed the bony density feature of the mass. Surgical excision confirmed that the lesion was an osteochondroma.

Based on pathological findings, 5 German shepherds, revealed a mean age of 7.6 years, showing no clinical signs were diagnosed as tracheopathia osteochondroplastica(TOC). Grossly, multiple small-sizecd nodules, appeared as cobble-stones, on the cartilage rings situated in the anterior trachea and the mucosal surface of the epiglottis were showed. Numerous tiny nodules were scattered on the pleural surface of the lung. The vascular walls of the heart were irregular and coarse apearance with calcification. Histopathologically, nodules in the trachea represented an irregular expansion of the underlying tracheal ring with protrusion into the submucosa and consisted of proliferated and calcified cartilage and bone with marrow spaces containing numbers of hematopoietic cells. Pulmonary calcinosis and calcification of the vascular walls of the heart were observed. Our observations suggested that TOC arises form eccondroses and exostoses of the tracheal cartilage rings.

Hereditary multiple exostosis (HME) is an autosomal dominant disorder manifested by the presence of multiple osteochondromas. Although the lesions are benign in nature, exostoses are often associated with characteristic progressive skeletal deformity and displaying clinical symptoms such as mechanical irritation or impingement. We present the successful arthroscopic resection in a 24-year-old HME male with impingement syndrome and long head tendon tear of the biceps caused by osteochondroma arising from the distal clavicle.

Osteomas of the external auditory canal are considered clinically to be discrete, pedunculated bone lesions arising along the tympanosquamous suture. They are benign lesions but often are slowly progressive growth in size which eventually resulted in obstruction of the external auditory canal when this occurs the patient will complain of deafness. Exostoses, similar to the osteoma, are broad based elevations of bone usually multiple and bilaterally symmetric, involving the tympanic bone. Recently, the authors have experienced a case of osteoma of the external auditory canal, and so report with some reviews of the literatures.

Purpose: Torus palatinus is a bony prominence at the middle of the hard palate. The size varies from barely discernible to very large, from flat to lobular. This oral exostosis is not a disease or a sign of disease, but if large, may be a problem. So, we present the clinical and histopathologic features and applied therapy and provide a comprehensive review of the rare case of the symptomatic exostoses. Methods: A 37-year-old woman had slowly growing exophytic nodular mass of the bone that arises the midline suture of the hard palate. The patient was concerned about discomfort associated with movement of her tongue and about frequent irritation of the palatal mucosa during mastification of the hard food. The patient had a large, unilobulated torus palatinus. It extended from the area adjacent to the canine to a point beyond the junction with the soft palate. The mass was oblong in shape, measuring about 3 cm long, 2 cm wide, and 0.8 cm in height. Results: Before surgical intervention a CT was obtained for the sake of estimating the thickness of the bone between the exostoses and the maxillary antrum and floor of the nose. The surgical procedure was performed with the patient under general anesthesia. Removal of the exostosis was performed after midline mucoperiosteal incision with osteotome and diamond burr. Histologic finding revealed decalcified dense bony tissue, the presence of lacunae, and normal osteocytes. Conclusion: Surgical removal is recommended when one or more of the following condition exist: interference with the construction of prosthesis, interference with oral function, irritation or pathology of the overlying tissue, inability of the patient to maintain proper oral hygiene, and fear of malignancy or other psychologic trauma. We report a rare case of the torus arising in hard palate with symptoms.

Although breast implants have been in clinical use for almost 6 decades and have undergone considerable development during this time, implant rupture is still a dreaded long-term complication. Some obvious external factors, such as trauma, can lead to implant rupture, but many studies have reported a high rate of "spontaneous" implant rupture. Herein, we present two cases with the aim of raising awareness of a new possible cause of "spontaneous" implant rupture: mechanical irritation by bony protrusions.
