Decompression is considered an effective treatment for odontogenic cystic lesions in the jaw. A variety of decompression devices are successfully used for the treatment of keratocystic odontogenic tumors, radicular cysts, dentigerous cysts, and ameloblastoma. The purpose of these devices is to keep an opening between the cystic lesion and the oral environment during treatment. The aim of this report is to describe an effective decompression tube using a stainless steel tube and wire for treatment of jaw cystic lesions.

The basal cell nevus syndrome is a well recognized entity, the major symptoms of which are basal cell nevi, multiple jaw cysts, skeletal anomalies, and ectopic calcification. The syndrome follows a hereditary pattern, which is characterized by a highly penetrant, autosomal dominant gene with multiple and variable effects. The patient often has a characteristic face, with frontal and temporoparietal bossing, which results in an increased cranial circumference. The eyes may appear widely separated, and 40 percent of patients have true ocular hypertelorism. Jaw cysts are one of the most constant features of the syndrome and are present in at least 75 percent of the patients. The cysts are odontogenic keratocysts and frequently multiple. Radiographically, the cysts in patients with basal cell nevus syndrome do not differ significantly from isolated keratocysts. The cysts in patients with this syndrome are often associated with the crowns of unerupted teeth; on radiographs they may mimic dentigerous cysts. We report a case of multiple odontogenic keratocysts associated with basal cell nevus syndrome with the literature of review.

We present two cases of multiple jaw cysts not associated with basal cell nevus syndrome. Case 1: a nine year-old boy visited CNU Hospital for orthodontic treatment and his radiographs showed cystic lesions surrounding the crowns of teeth #13 and #17 respectively, which were diagnosed as dentigerous cysts. Subsequently, two more cysts were found on his follow-up radiographs in 12 and 15 months. The two cysts were determined to be odontogenic keratocysts. The boy had no skeletal abnormalities and no skin lesions associated with basal cell nevus syndrome. Case 2: a fifty-eight year old man had three impacted third molars with pericoronal radiolucencies, which were diagnosed as dentigerous cysts. He had no additional abnormalities associated with basal cell nevus syndrome. Multiple jaw cysts can occur at any age, and periodic radiographic surveillance may be needed for any cases of impacted tooth.

BACKGROUND: For normalization of displaced anatomical structure by large cyst, two-step procedure (decompression and enucleation afterward) has been recommended. However, the histological transformation after cystotomy for decompression was shown frequently in secondary enucleation. Therefore, analyses about effects and histological changes after decompression have been necessary. METHODS: 48 cases diagnosed as large odontogenic cyst in the jaw and treated by decompression and secondary enucleation were retrospectively analyzed in clinical, rediographical, and histological aspects. RESULTS: In dentigerous cyst, decompression was much useful. Impacted permanent teeth were erupted and reduction rate was higher than that of odontogenic keratocyst (OKC) and apical periodontal cyst. In OKC, among the 29 cases, 11 cases showed no-keratosis, proliferation and rete-ridge elongation after decompression. 4 cases showed no-keratosis, only. 7 cases showed orthokeratosis and rete-ridge elongation and 6 cases showed reteridge elongation, only. 1 case had no change. And the recurrence rate for OKCs was 10.3%. For all odontogenic cysts in this study, dysplasia was not found in cystic lining after decompression. CONCLUSIONS: This study implied that decompression for large odontogenic cyst was useful treatment modality because it was conservative treatment and recurrence rate was low although long treatment period was required.

jaw cysts which were diagnosed histopathologically in the Department of Oral and Maxillofacial Surgery, Wonkwang University Dental Hospital from Jan. 1, 1991 to Dec. 31, 1998. Medical records, radiographs, histopathological reports of 214 cases with jaw cysts were retrospectively reviewed. The results were as follows: 1. Among the total patient of 214 cases, male were 143 cases, and female are 71 cases, male predominated by the ratio of 2.04. 2. The periapical cysts and the dentigerous cyst are the most common cyst, irrespective of 116 cases(54.2%) and 58 cases(27.1%). 3. The periapical cyst has no gender prediction, male were 70 cases and female were 54 cases, the mean ages were 39.3 years(SD=18.4). The most common involving teeth were maxillary anterior teeth(59.7%). 4. The dentigerous cyst predominantly occurred in third decade (18 cases : 31%), and the mean ages were 31.9 years(SD=14.8). Dentigerous cysts predominantly occurred in male by the ratio of 7.29 (male : 51 cases, female : 7 cases). Maxillary anterior teeth(43.1%) and mandibular molars(32.8%) were most frequently involved. 5. The odontogenic keratocyst predominantly occurred in second and third decade and mean ages were 23.5 years(SD=17.2). The mandibular molars(60%) were most frequently involved. 6. All nasopalatine cyst occurred after fourth decade, mean ages were 49.5years(SD=10.4). In the gender incidence of nasopalatine cyst, 1 case occurred in female and 10 cases occurred in male. 7. In the surgical intervention of jaw cyst, cyst enucleation and marsupialization performed in 156 cases. Cyst enucleation with bone graft performed in 58 cases and iliac autogenous bone grafts most frequently performed in 29cases. 8. The diameter range of cyst enucleation with bone graft were from 15mm to 120mm with a cyst diameter of 33.3mm.(SD=15.2) The diameter range of cyst enucleation and marsupialization were from 7mm to 82mm with a cyst diameter of 20.4mm.(SD=9.0) The diameter of cyst enucleation with bone graft were significantly greater than diameter of cyst enucleation.(p<0.05) 9. Post-operative complications occurred in 9 cases(15.5%) in which cyst enucleation with bone grafts performed and occurred in 31 cases(19.9%) in which cyst enucleation.]]>

Dentigerous cysts are benign odontogenic cysts that are associated with the crowns of permanent teeth. They are developmental epithelial-lined lesions which are formed from fluid accumulation in the space between the reduced enamel epithelium and the surface of crown. This may occure due to the obstructin of venous return caused by tooth impaction. The most prevalent location of dentigerous cysts are the third molar of mandible. While the single dentigerous cysts are the second most common odontogenic cysts following the radicular cysts of jaw, multiple cysts are observed in patients with some conditions such as mucopolysaccharidosis type IV, basal cell nevus syndrome, and cleidocranial dysplasia. They occur in young patients in the second or third decades of life, but it is a rare occurrence for children. A sixteen-year-old girl with painful swelling in the right mandible visited to our department. All routine laboratory test results were within normal limits. However, we were able to diagnose that she had facial asymmetry. Computed tomography showed a well-defined soft tissue mass obliterating right mandible ramus with an impacted tooth. We performed total enucleation of cyst and molar tooth. The pathology revealed a non-keratinized squamous epithelial lined cyst associated with an undamaged tooth.

The basal cell nevus syndrome (BCNS) is an autosomal dominant disorder, characterized by basal cell carcinomas, odontogenic keratocysts and skeletal abnormalities. We experienced two cases that represented several characteristics of BCNS. Case 1: a thirty three year-old man visited CSU hospital. His radiographs showed four cystic lesions at both maxillary sinus and both mandibular angle, with bifid rib and ectopic calcification of falx cerebri. After marsupialization and enucleation, recurrent and newly developing tendency were found on his follow-up radiographs. Case 2: a seventeen year-old man had four large cystic lesions which were diagnosed as odontogenic keratocysts. He had craniofacial anomalies which included ectopic calcification and frontal bossing.

Dentigerous cysts are the most common type of developmental odontogenic cysts and the second most common odontogenic cyst of the jaw after radicular cysts. Dentigerous cysts are usually solitary, but can be multiple in patients with certain syndromes, such as mucopolysaccharidosis type IV. There are cases of multiple cysts occurring in non-syndromic patients as well. A fourteen-year-old girl presented to our department with painful swelling in the left cheek. Except for the bulging of the left nasal lateral wall, the physical examination was unremarkable and all routine laboratory test results were within normal limits. Computed tomography (CT) showed a well-defined soft tissue density obliterating both maxillary sinuses with a tooth in the medial wall. We removed the cyst and teeth with forceps via a large middle meatal antrostomy. The pathology revealed a non-keratinized squamous epithelial lined cyst associated with the teeth.

Dentigerous cysts are major pathologic entities found in dentistry, accounting for approximately 24% of all true cysts in the jaws. They are the most common type of developmental odontogenic cysts and the second most common odontogenic cyst of the jaw, after radicular cysts. They are associated with the crown of an unerupted or impacted tooth. About 95% of dentigerous cysts involve permanent dentition, and only 5% are associated with supernumerary teeth. To date, a dentigerous cyst containing multiple teeth has rarely been reported. Reported herein is a 51-year-old man who presented a history of painful palpable mass on the right cheek area, and who was found to have a maxillary dentigerous cyst containing multiple teeth. The cyst with multiple teeth was successfully removed via endoscopic endonasal and intraoral approaches.
