Pilomatricoma(or calcifying epithelioma) is a not common benign solitary tumor originated from outer root sheath cell of hair follicle or hair follicle of sebaceous glands. The tumor usually presents as an asymptomatic, hard, superficial located, and skin colored to reddish blue cutaneous mass. Most of the tumors are less than 10mm in diameter and adherent to the skin. Recently, 48-year-old man presented with cheek mass. The tumor was 2.6cm sized and located at the subcutaneous layer of cheek on CT scan. The tumor was clearly removed via transoral approach with buccal incision leaving no wound on face. The mass was confirmed as pilomatricoma on pathologic examination. Herein, we report our experience with literature review.

The endoscopic assisted approach for the treatment of condylar fracture is a less invasive alternative treatment modality and is considered to be able to overcome the limited access to the operation field to obtain an accurate reduction and fixation. Six patients with condylar neck and subcondylar fracture underwent the endoscopic assisted open reduction and internal fixation through the transoral approach at the Department of Oral and Maxillofacial Surgery, Seoul National University Dental Hospital. The endoscope was inserted through an intraoral incision and the reduction of fracture fragment was performed via a transbuccal approach with two transcutaneous stab incisions. Five patients showed anatomic reduction without any complications. One patient, whose fracture site was fixed with a single plate, showed displacement of fractured condylar segment during the follow up period. No patient had any facial nerve damage.

The displacement of an entire tooth into the adjacent anatomical area is an uncommon complication of a tooth extraction. We encountered a 23-year-old woman who had previously undergone surgery under local anesthesia to remove the lower third molar about 12 weeks prior and the upper third molar was extracted 2 days prior to visiting this hospital. Upon admission, she complained of a swallowing discomfort and a mouth opening limitation. Panoramic radiograph and a CT scan revealed a displacement of the entire tooth into the lateral pharyngeal space. The tooth was retrieved via the transoral approach under general anesthesia. The removed tooth had an indentation formed by a dental bur. Therefore, it was concluded that the tooth displaced into the lateral pharyngeal space was the lower third molar. This report describes an unusual case of a third molar that was displaced into the lateral pharyngeal space with a review of the relevant literature.

The submandibular gland is the second largest major salivary gland, which secretes 40% of the total daily saliva. Owing to its anatomic characteristics as well as the high viscosity and basicity of the saliva, sialolithiasis is found most commonly in the submandibular gland. Sialolithiasis that cannot be treated by conservative treatment is conventionally removed by an excision of the submandibular gland. Generally, an excision of the submandibular gland is performed via an extra-oral approach but the disadvantages of this treatment include a risk of injuring the facial nerve and scar formation. Case reports have revealed an even less invasive intraoral surgical technique for the removal of sialolith that does not affect the submandibular gland function. The functional recovery of the gland, complications and recurrence rates after surgery with this conservative intraoral procedure were all successful. We report 5 patients from the department of Oral and Maxillofacial Surgery at Dental Hospital, Yonsei University, who had undergone a resection of the sialolith though the intraoral approach with successful results.

Eagle's syndrome is the term given to symtomatic elogation of the styloid process or mineralization of the stylohyoid or stylomandibular ligament. Since ossification of stylohyoid ligament at cadeva was fist described by De Manchetis in 1652 and Weinlecher described clinical symptom which produced by elongated styloid process and osteotomy of styloid process in 1872, Clinical symtom which include sensation of a foreign body on the pharynx, dysphagai, dysphonia, referred pain, and mouth opening disturbance was termed by Eagle as Eagle's syndrome. then, case reports of Eagle's syndrome are presented. in these cases, the patient's chief complaints included periauricular radiating pain, mouth opening disturbance, foreign body sensation, dysphagia, tenderness on the neck. Through vairous X-ray examination and palpation of tonsillar fossa, elongated styloid process were confirmed. Under the general anesthesia there were successfully removed out via transoral approach technique, described by Eagle. after resented styloid process, they were freed from the symptoms without further complication. Therefor we reported these cases treated by surgical resection of styloid process with good results.

Angioleiomyoma is benign smooth muscle tumor originating from the vascular wall. While they can occur in various anatomical locations, they are rarely reported in the vallecula region of the oropharynx. We present a case of a 58-year-old female patient with a five-year history of progressive dysphagia and throat discomfort. Laryngoscopy revealed a large, soft, mobile mass located on the right side of the vallecula. Radiological imaging further characterized the lesion as a well-circumscribed, heterogeneous mass. Surgical intervention in the form of Transoral Videolaryngoscopic Surgery (TOVS) was performed, leading to the successful removal of the mass. Histopathological analysis confirmed the diagnosis of angioleiomyoma.

Purpose: Anatomical reduction of the fractured condylar process is an important prerequisite for re-establishing function. The authors reported about effectiveness of transoral approach for mandibular subcondyle fracture using trochar device in cases that the fracture line is below the reference line, the perpendicular line of the longitudinal axis of condylar process passing the lowest point of sigmoid notch. As a serial study, we report the open reduction via preauricular approach for mandibular condyle fracture, in cases that the fracture line is above the reference line. Patients and Methods: Sixteen condylar fractures of 15 adult patients were divided two groups and treated by open reduction via preauricular approach (8 cases) or by closed reduction (8 cases). The degree of maximal mouth opening, occlusion, anatomical reduction, condylar resorption and complications were assessed and evaluated for the two groups. Results: The open reduction of condyle via preauricular approach leads to good results without permanent complications. Anatomical reduction of open reduction group and maximal mouth opening range of the closed reduction group is significantly better than the other group. No significant differences were found in the condylar resorption and the occlusion. Conclusion: The preauricular approach was useful to reduce and fix the condylar fragment, in cases that the fracture line is above the reference line.

Eagle's syndrome is the manifestation of elongated styloid process that is not a common entity in dental clinics. Without the knowledge of this syndrome misdiagnosis can be made and therefore differential diag-nosis with other diseases of oral and maxillofacial area is required. The symptoms of elongated styloid process are cervical pain, foreign body sensation, dysphagia and pharyngeal pain. A 27 years old male vis-ited our hospital. He had cervical pain with unilateral facial nerve palsy. Along with meticulous clinical examinations, 3D-CT, Plain radiographic studies were used to make the diagnosis. In computed tomogra-phy, Lt. styloid process was elongated and fractured. Patient have undergone surgical resection of elongat-ed styloid process and have been carefully observed. Characteristically, preoperative facial nerve palsy showed rapid postoperative recovery. The other clinical symptoms that were present in the initial visit were diminished. The purpose of this article is to report a case of Eagle's syndrome presenting unilateral facial nerve palsy that was treated with transoral surgical approach with literature review.

The zygoma is protruded on both sides of the midface and plays an important part in determining the impression of face. There are much different esthetic consideration of zygomatic prominence between the oriental and western. Because slight prominent zygoma is thought to be esthetic in the western, there has been done many augmentation therapy. But, in the oriental, prominent zygoma, especially in the female, is thought to be aggresive and manlike image, there has been done many zygoma reduction therapy. There are two methods to reduce the prominent zygoma, one is shaving method and the other is zygoma repositioning with ostectomy. The approach to zygoma and zygomatic arch without surgical morbidity is very difficult, so this problem has been difficult subject to oral & maxillofacial surgeon in a long period. We report the treatment case of facial asymmetry with the unilateral zygoma reduction & genioplasty using only intraoral approach with the retrospective study.
