골내 표피낭종은 드문 양성 낭성 병변이다. 이는 선천적인 요인이나 외상의 결과로 사료되며, 골 주변의 연부 조직에서 발생하기 때문에 골 파괴를 유발할 수 있다. 골내 표피낭종의 단순방사선 소견은 피질골의 팽대를 동반한, 경계가 명확한 방사선 투과성 병변이다. 임상적, 방사선학적 소견이 유사하기 때문에 원위 지골에서 발생한 다른 질환들과 골내 표피낭종을 감별하는 것이 중요하다. 저자들은 원위 지골에서 발생한 골내 표피낭종의 2개의 드문 증례를 보고하고자 한다.

Aneurysmal bone cyst (ABC) is a rare non-neoplastic bone lesion that involves mostly the long bones and vertebrae and may occur very rarely in the craniofacial bones. ABCs may occur as secondary bony pathologies in association with various benign and malignant bone tumors and with fibrous dysplasia (FD). FD is a common non-neoplastic bony pathology mostly affecting craniofacial bones. Secondary ABC occurring in craniofacial FD is extremely rare, with only approximately 20 cases reported in the literature to date. Here, we report on a case of secondary ABC in a 25-year-old woman who has had a craniofacial deformity for over 10 years and who presented to us with a rapidly growing painful pulsatile mass in the right frontal region that began over 2 months prior to admission. On thorough examination of computed tomography and magnetic resonance imaging brain scans taken at two-month interval, an aggressive, rapidly enlarging ABC, arising from the right frontal FD, was diagnosed. The patient underwent preoperative embolization followed by gross total resection of the ABC and cranioplasty. The 6-month follow up showed no recurrence of the ABC, nor was any progression of the FD noticed.

Fibrous dysplasia (FD) is a rare skeletal disorder characterized by abnormal fibro-osseous connective tissue replacing normal bone. Despite its benign behavior, craniofacial FD can cause morphological disfigurement, headache, and even blindness as a result of the produced mass effect. Surgical resection is recommended when the patient shows apparent clinical symptoms or aggravating facial asymmetry. Postoperative complications have been reported, such as hematoma, surgical site infection, abscess formation, resorption of the bone graft used for reconstruction, and recurrence. An aneurysmal bone cyst (ABC) is a rare benign bony lesion that can occur secondary to preexisting bone tumor. Secondary ABCs in craniofacial FD are extremely rare in the literature, accounting for less than 30, all of which are either case reports or series. We report an extremely rare case of symptomatic secondary ABC arising from craniofacial FD that had been misdiagnosed with abscess formation or recurrence and was surgically removed. Notably, 17 years elapsed between the primary surgery and the complication of secondary ABC. The patient underwent total removal of secondary ABC. After surgery, symptoms were relieved, with no recurrence observed during a 6-month follow-up.

Frontotemporal dermoid cysts with a cutaneous sinus tract in the sphenoid bone are rarely found, and furthermore, the spreading of these cysts across the frontal branch of the facial nerve has not been reported. Herein, we present a 5-year-old case of a dermoid cyst successfully resected with preservation of this nerve using a combined extracranial and intracranial approach. This approach is recommended for a safe and radical resection of the lesion and for securing an aesthetic outcome.

The purpose of this study is to report on five cases treated with bone graft using recombinant human bone morphogenetic protein-2 (rhBMP-2) on jaw defects after cyst enucleation. We performed bone graft with BMP (rhBMP-2+${\beta}$-tricalcium phosphate/hydroxyapatite) wrapped with a collagen sponge on jaw defects after cyst enucleation. Postoperative panoramic radiographs were taken periodically. After 1 to 12 months, bone remodeling was observed in the jaw defect area. In our cases, there were few signs or symptoms of recurrence of the cyst during the follow-up period.

We treated 19 cases of unicameral bone cysts with methylprednisolone acetate (MPA) from January 1988 to December 1995. We evaluated the effect of MPA injections through simple follow-up radiographs according to Oppenheim's, classification and retrospectively reviewed the sites of cyst, age of the patients at diagnosis, the incidence of pathologic fracture, cystic nature, and cystic proximiy to the growth plate, We then analyzed the relationship between these variables with the results of MPA injections. According to Oppenheim's classification, the results with the use of MPA injections were as follows: healed in six cases, improved in seven cases, incomplete obliteration in five cases and recurred in one case, If healed and improved were considered satisfactory results, then 13 cases(68.4%) were satisfactory at the last follow-up. Sites of cyst, age of the patients at diagnosis, incidence of pathologic fracture, cystic nature and cystic proximiy to the growth plate appeared not to influence the results of MPA injections statistically. On these data, we thought that the treatment of unicameral bone cysts with MPA injection was the most effective first choice of treatment before operative options such as curettage and bone graft.

A dentigerous cyst is an epithelium-lined sac that surrounds the crown of an impacted, embedded, or unerupted tooth. Many surgical procedures have been described for the elimination of dentigerous cyst, but they can be devided into two basic group: enucleation and marsupialization. Marsupialization is a conservative technique which allows the reduction or elimination of a cystic lesion by making it an accessory compartment to the oral cavity and it is the best way to conserve a tooth affected by dentigerous cyst and to permit its eruption, especially in young patient. After using marsupialization to treat dentigerous cyst associated with the crown of unerupted premolar in young patient, the results were as follows: 1. Reduction of bony expansion and rapid bone regeneration without infection and recurrence were observed. 2. Normally spontaneous eruption of involved teeth were permitted, as well as loss of affected tooth was avoided. 3. Follow-up examinations revealed no complication and recurrence.

목적: 소아에 발생한 고립성 골낭종에 대해 경피적 자가 골수 및 이종골의 혼합 이식을 이용한 치료의 결과를 알아 보고자 하였다. 연구대상 및 방법: 1996년 1월부터 1999년 2월까지 경피적으로 자가 골수 및 이종골의 혼합 이식을 이용하여 치료한 고립성 골낭종 7예를 대상으로 하였다. 성별 분포는 남자가 4예, 여자가 3예였으며, 평균 연령은 10세(6~15), 평균 추시 기간은 35.6개월(20~52)이었다. 발생 부위별로 상완골 근위부 및 간부가 3예, 대퇴골 근위부가 3예, 장골(Ilium)이 1예였으며, 병소의 면적은 평균 14.7 $cm^2$(10~23)였다. 활성도는 활성형이 6예, 비활성형이 1예였으며, 과거력상 스테로이드 주입술을 시행받은 경우는 5명으로 평균 3.2회였다. 치료에 사용된 골수의 양은 평균 14.3 ml(10~20)였으며, 이종골로는 $Lubboc^{(R)}$(Transphyto S.A. Clermont Ferrand, France)을 사용하였으며 사용 갯수는 평균 6.4개(5~10)였다. 결과는 Neer의 분류법에 따라 판정하였다. 결과: 낭종의 전체가 신생골로 대체되어 완전한 치유를 보인 경우가 5예, 전체적으로 골 경화가 보이지만 부분적인 낭종이 관찰되는 경우가 2예로, 전예에서 만족스런 결과를 보였으며 수술중이나 술후에 합병증의 발생은 없었다. 결론: 고립성 골낭종의 치료를 위한 경피적 자가 골수 및 이종골의 혼합 이식술은 비교적 쉽고, 수술로 인한 합병증이 적으며, 치유율이 매우 높을 뿐만 아니라, 자가골 이식으로 인한 공여부의 문제점을 피할 수 있어 권장할 만한 좋은 치료법이라 생각된다.

Subchondral cysts are frequently encountered in patients with temporomandibular joint osteoarthritis (TMJ OA), particularly in advanced stage. Subchondral cysts within osteoarthritis are typically lying adjacent to the joint surface where initial load bearing occurs during activity and have been associated with greater pain and disease progression. Although the etiology of these cysts remains uncertain, recently studies report that the induction of the subchondral bone mechanical stress caused subchondral cysts. Repeated overloading leads to further deterioration of subchondral bone which render subchondral bone structure more fragile, increase the risk of osteoarthritis progress. The purpose of this study was to assess the effect of conservative treatment and longitudinal osseous changes of a large subchondral cyst in a mandibular condyle in a symptomatic TMJ OA patient.

Eosinophilic granuloma is a common expression of Langerhans cell histiocytosis and corresponds with typical bone lesions. The radiographic appearance of eosinophilic granuloma in the jaw is variable and not specific. It may resemble periodontitis, radicular cyst, or malignancies. The purpose of this report is to describe the characteristic radiographic features of eosinophilic granuloma of a 39-year-old male. The lesion in the anterior mandible was first diagnosed as radicular cyst because the radiographic findings were ovoid radiolucent lesion with well-defined border. However, careful interpretation revealed a non-corticated border and floating tooth appearance that were the characteristic radiographic features for the differential diagnosis. Early clinical signs of eosinophilic granuloma can occur in the jaw and a bony destructive lesion might be mistaken for periodontitis or an odontogenic cystic lesion; therefore, careful interpretation of radiographs should be emphasized.
