PURPOSE: Among the various surgical methods used for the effective treatment of cystic lesion in the jaws historically, decompression procedure has some of superior prognosis compare to direct enucleation. In order to propose the efficacy of decompression we performed this retrospective study to compare decompression procedure with one-stage enucleation in clinical results and prognosis. PATIENTS AND METHODS: We reviewed 175 patients who had been histopathologically diagnosed cystic lesions from 1996 to 2000 in our department. Patients who had been received decompression alone or secondary enucleation after decompression were 31 cases, and enucleation alone were 144 cases. The age and sex of the patients, the area, size, and histological type of the lesions, and detailed operation and complications including recurrence were investigated. The minimal follow-up period was 2 years. RESULTS: In 31cases of decompression, male patients were 22cases(71%) similar to male predilection(62.3%) in total 175 cases. Cystic lesions were developed evenly in all age groups totally. Decompression was mainly performed in teenagers but enucleation was used in elder decades. In decompression cases the lesions were located in mandibular posterior, maxillary posterior, mandibular anterior, and maxillary anterior in order, which had some differences in total and enucleation cases. In enucleation cases, less than 3cm in size was 77.1% but larger than 3cm was 93.5% in decompression cases. Histopathologically, dentigerous cysts(54.8%), unicystic ameloblastomas(16.1%), and odontogenic keratocysts(12.9%) were seen in decompression cases and no recurrence or metaplasia and infection was observed. On the other hand, permanent tooth loss, numbness, recurrence, and so on were accompanied after enucleation. CONCLUSION: Although decompression procedure has disadvantages such as many of visiting times and slow recovery of the surgical defect, decompression is the best choice of treatment for large cystic lesions of the jaws, because it prevents functional and cosmetic defect, allows bone regeneration, and makes easy secondary enucleation.

Direct arterial pressure(DAP) and heart rate were observed in normal patients during and after intravenous injection of d-Tc at varying rates of administration. The injection of d-Tc was preceeded by antihistmine(hydroxysine) in group ll. The results were as follows: 1) Alteration of pulse rate was minimal following varied administration of d-Tc in all groups. 2) DAP showed maximal change following a bolus injection of d-Tc, and a minimal change at the end of 180 seconds of d-Tc administration. 3) DAP showed minimal change following the premediction with antihistamine in comparison to a bolus administration. 4) Manifestation of flushing and tachycardia due to histmine release were not observed in group l and group ll.

BACKGROUND AND OBJECTIVES: It has generally been accepted that closed reduction is the management of nasal fracture in children. But proper management is still confusing and clinical and radiological evaluation about long term results have yet to be determined. The purpose of this study is to determine which closed reduction method for nasal bone fractures in children is effective when considering clinical and radiological aspects. MATERIALS AND METHOD: We analysed the medical records of 35 children with nasal bone fractures up to the age of 15, who were operated by closed reduction between 2000 and 2002. We evaluated postoperative satisfaction of doctors and patients and postoperative CT scan score (Motomura et al 2001) of 14 children over more than at least 2 postoperative years. RESULTS: A peak incidence ages ranged from 13 to 15 years. The most frequent cause was sports injuries. The degree of postoperative satisfaction and postoperative CT scan score was favorable. CONCLUSION: In management of nasal fracture in children, closed reduction is effective and satisfactory when clinical and radiological aspects are considered.
