Ectopic eruption of a tooth into the oral environment occurs commonly whereas ectopic eruption of a tooth into other sites is rare. Those that have been reported include the nasal cavity, chin, mandibular condyles, coronoid processes, orbits and maxillary sinus. The etiologic factors of ectopic eruption are developmental disturbances such as cleft palate and teeth displaced by trauma or cysts, maxillary infection, genetic factors, crowding and exceptionally dense bone. In many cases, however, the etiology cannot be identified. Eruption of the teeth into the maxillary sinus is uncommon, however the identification of such teeth can be important since they have the potential to cause considerable morbidity. The definitive treatment is surgical removal of the teeth. A 7 year-old-boy visited the Department of Pediatric Dentistry, College of Dentistry, Yonsei University for treatment of dental caries. The abnormal erupting paths of the left and right maxillary canines were found during routine panoramic radiographic investigations. A panoramic radiograph taken at 13 years old revealed that two maxillary canines were located into the sinus. The teeth were extracted by the Caldwell-Luc approach.

Supernumerary teeth are teeth which result from the continued budding of the enamel organ of the preceding tooth or from excessive proliferation of cells. They are most often found in the maxillary anterior region. And they can be responsible for a variey of irregularities in the primary and transitional dentition. There are two morphological types of supernumerary teeth, supplemental and rudimentary. Supplemental teeth have normal shape and size. In contrast, rudimental teeth have abnormal shape and smaller size. Supplemental supernumerary teeth are most common in permanent lateral incisor area. Its extraction must be decided more carefully with differential diagnosis between normal teeth, because it has normal shape and size. We reports 3 cases of the normal incisor shaped teeth in the maxillary anterior region. In all cases, we used the 3D Dental-CT as well as the conventional plain film such as periapical, occlusal, and panoramic radiograph. Consequently, 3B Dental-CT was valualble to figure out the exact position and morphology of supernumerary teeth, to do more conservative surgery and to reduce surgery stress and time.

The laryngeal carcinoma is the most frequent malignant tumor in the E.N.T. field. In the surgical treatment of laryngeal carcinoma, in 1873, Billroth performed the first total laryngectomy, and in 1863, H. B. Sands performed the first partial laryngectomy. Recently general advances (antibiotic therapy, blood trasfusion, and safer anesthesia) result in the improvement of postoperative prognosis. Because the laryngeal lymphatic system has the characteristic compartmentation, this serves the anatomic basis for performing the partial laryngectomy. Although the indications of partial laryngectomy are different from that of total laryngectomy, the partial laryngectomy has the advantage of not only removal of all malignant disease, but also maximum preservation of respiratory, phonatory, and sphincteric function of the larynx. In the latest, surgical treatment decreased the frequency of recurrence, and also increased the 5 year survival rate with combination of the chemotherapy and radiation therapy. The authors have experienced 8 cases of partial laryngectomy for laryngeal carcinoma at the department of otolaryngology, Korea University Hospital from 1980 to 1982. Among the total 8 cases, 2 cases were involved only in the epiglottis, 2 cases in the anterior 1/3 of both vocal cords with ant. comissure, 2 cases in the middle 1/3 of Lt. vocal cord, 1 case in the anterior 1/3 of Rt. vocal cord with ant. comissure, and another 1 case in the Rt. ventrical. So authors report these cases with review of the literature.

Background: Esophageal injury requires early and proper management. We want to determine the results of various esophageal injuries. Material and Method: We respectively analyzed 22 patients who were managed for esophageal injury between 1999 and 2009. Based on the medical records, we reviewed the causes of injury, the diagnoses, the treatment methods, the complications and the prognosis. Result: The main causes of esophageal injury were a foreign body in 9 cases (41%) and vomiting in 5 cases (23%). We treated the patients with esophageal primary repair in 12 cases (55%), abscess drainage in 4 cases (18%) and conservative management in 6 cases (27%). There was esophageal leakage in 7 cases (32%) and death occurred in 3 cases (14%). Conclusion: For minor esophageal injury, conservative management was sometimes possible to treat the esophagus, yet aggressive and urgent surgical treatment should be applied for cases of major esophageal injury, including mediastinal abscess.

Ameloblastic fibroma (AF) is a rare odontogenic ectomesenchymal tumor that is frequently seen in the first two decades of life, and occurs in the mandible. The most proper management of AF has been a recent topic of debate because of its recurrence and malignant transformation. This report describes AF in a 4-year-old male, which was a unilocular radiolucency on the maxillary right primary molar area with a scalloped border and corticated margin. The tumor was treated conservatively with enucleation and curettage, and the decision was made to preserve the right primary second molar. A biopsy confirmed it as AF. During the 43 months of follow-up, the patient had no evidence of recurrence or malignant transformation. Moreover, the radiographic examination revealed the generation of tooth germ to be a permanent second premolar. This report shows a case of AF in the posterior maxilla of a 4-year-old boy and discusses the conservative therapeutic approach to this tumor. Therefore, the age of the patients should be an important consideration when choosing conservative or radical surgery in a young AF patient.

With the increase of participation in the sport activities, there has been a commensurate rise in the number of sport injuries. A more commonly encountered injured region in the upper-extremity is the wrist. Sport injuries are often characterized as overuse and traumatic. Traumatic injuries include fractures, dislocations, and ligament tears often seen in contact or collision sports. Overuse injuries, represented damages by a level of repetitive microtrauma sufficient to overwhelm the tissues$^{\circ}{\O}$ ability to adapt, include inflammatory conditions such as De Quervain$^{\circ}{\O}s$ disease, extensor carpi ulnaris tendinitis, intersection syndrome. Also included is a traumatic problem such as stress fractures of the hook of the hamate, subluxation of the extensor carpi ulnaris tendon, chronic scapholunate instabilities, and degenerative triangular fibrocartilage tears. This review will focus on both overuse and traumatic injuries of the wrist in the athletes. A significant emphasis will be placed on the evaluation, pearls and pitfalls of conservative and operative treatments.

Osgood-Schlatter's disease is generally treated conservatively. However, surgical treatment is necessary for some patients with recurrent or persistent pain that does not respond to conservative treatment. Most authors recommend the excision of the loose ossicles present around the distal end of the patellar tendon. The authors report the technique of arthroscopic removal of the ossicles for Osgood-Schaltter's disease instead of the conventional technique through the incision at the tibial tuberosity. The advantages of this technique are less damage to the patellar tendon, early postoperative recovery, making no incisional scar in front of the tuberosity which causes the scar discomfort in kneeling, and more cosmetic result.

Traumatic pulmonary cysts are rare cavitary pulmonary lesions following nonpenetrating thoracic trauma. The pathogenesis of this lesion Is a tear in the pulmonary parenchyma with leakage of air and fluid into this tear. The diagnosis is one of exclusion, based on an awareness that lung cyst can develop after trauma. Once traumatic lung cyst is diagnosed, the principle of the treatment is in-hospital obser- vation with respirato y support. However, if a cyst is complicated by infection unresponsive to a trial of appropriate antibiotic therapy and does not progressively become smaller, surgical intervention is indicated. Authors recently experienced a case of traumatic lung cyst in a 19 year-old man. Case presentation and review of articles on traumatic pulmonary cyst follows.

Nerve compression is caused by external force or internal pathology, which symptom develops along nerve distribution. There are median, ulnar and radial nerve compression neuropathies below elbow. Carpal tunnel syndrome at the flexor retinaculum is most common among all the entrapment neuropathies. Other causes of median nerve neuropathy include Struther's ligament, biceps aponeurosis, pronator teres, FDS aponeurosis and aberrant muscles, which induce pronator syndrome or anterior interosseous nerve syndrome. Ulnar nerve can be compressed at the elbow by arcade of Struther, medial epicondylar groove, FCU two heads, which develops cubital tunnel syndrome, at the wrist by ganglion, fracture of hamate hook and vascular problem, which develops Guyon's canal syndrome. Radial tunnel syndrome is caused by supinator muscle, which compresses its deep branch. Treatment is conservative at initial stage like NSAID, night splint or steroid injection. If symptom persists, operative treatment should be considered after electrodiagnostic or imaging studies.
