The major causes of the facial bone fractures are fractures are automobile collision or other accident, and fights. Of the facial bone fractures, the nasal bone fractures are monst common. According to Schroeder et al., 50% of facial bone fractures are isolated fractures of the nasal pyramid. But the fractured nasal bone is not immediately treated as other facial bone fractures. And it is necessary to delay the treatment of the combined nasal bone fractures with other jaw bone fractures because of the difficult anesthetic techniques. Therefore there are many residual nasal deformities following a fracture; nasal hump, saddle nose and alar rim defect. Many authors have suggested the methods to correct the post-traumatic nasal deformities. We have treated several patients with several methods and this paper presents the operating methods and results.

Treacher Collins syndrome(TCS) is a rare, incurable condition occurring in approximately 1 of 25,000 to 50,000 births. It may occur as a spontaneous mutation out of genetically normal parents or it may be manifested as an autosomal dominant pattern. TCS is characterized by facial deformities such as, underdevelopment of the maxilla, mandible and zygoma, malocclusion, bilateral deformities of auricles, antimongoloid slant of the palpebral fissures. The syndrome is often associated with cleft lip and palate, ear malformations and hearing loss, short stature, and anomalies of the heart and skeleton. Respiratory difficulty associated with air way obstruction may also be observed, and there is considerable difficulty in airway management during general anesthesia. It is necessary that dentists provide safe dental treatments and guidelines to TCS patients by providing adequate understanding about the characteristics of the syndrome and proper ways of managements. The purpose of this study is to report the dental and medical characteristics of the patient who visited the Department of Pediatric Dentistry, Yonsei University for multiple dental caries treatment and to review the literatures of TCS.

The Poland`s syndrome is very rare anomaly, which consists of congenital unilateral absence of the sternocostal part of the pectoralis major muscle, with ipsilateral hand deformities. The clinical features are variable but all patients have absence of at least the sternal head of the pectoralis major muscle. The syndrome is not hereditary and is of unknown origin. Early recognition of Poland`s syndrome may give the provision of psychologic and genetic counseling for anxious parents. We have encountered two patients with this entity, and one of them underwent successful surgical correction.

Deviated nose deformities have always been a surgical challenge, and it is essential to achieve both functional and esthetic improvements. Various techniques have evolved over time to correct deviated noses but no one method applies in all cases. Successful correction requires a complete understanding of the various surgical techniques and concepts, including the three-dimensional nasal structure and the time-related changes to surgically-treated noses.

Le fort 1 osteotomy surgery is one of the most popular surgical methods for the treatment of patients with facial bone deformities. An intermediate wafer splint is used to fix the bone segment to the planned position, but there are many steps that can cause errors. To reduce these errors, we propose a method of using a surgical guide made with virtual surgical simulation.

Lip canting is associated with facial asymmetry, and is one of the most challenging problems in surgical correction of facial deformities. The author corrected lip canting using bioabsorbable devices during orthognathic surgery. Soft tissue suspension procedures were performed on four patients with facial asymmetry. Lip lines improved for all patients. Over an observation period of five years, no complications were noted, nor did any late relapse develop. Furthermore, as time past, the effect of the Endotine suspension procedure increased probably due to induction of fibrosis on surrounding soft tissues.
