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.

This study was to analyze the changes of levels of alkaline phosphatase before and after enucleation of jaw cysts combined with bone grafting, and to evaluate biochemically the effectiveness of the early detection of bone healing and infection as a prognostic marker. Eighteen patients (13 males, 5 females) with cystic lesions of the jaws were divided into two groups. The bone graft group underwent enucleation and bone graft. The control group underwent only enucleation. Both groups were measured levels of ALP before surgery, and plus-minus 4 weeks postoperatively. The more discriminating results were obtained in the bone graft group. The results were as follows : 1. Levels of ALP after enucleation of jaw cysts were decreased in all patients with and without bone graft. 2. The bone graft group showed more marked decrease in variation of levels of ALP than the control group.(p=0.008) This should be considered as a result of increased osteoblastic activity and new bone formation. 3. Such variation could be used as a prognostic marker for bone healing after cyst operation. In the cost/benefit ratio, measurement of ALP activity could be useful as a convenient procedure in routine clinical practice.

PURPOSE: To evaluate the usefulness of a dental CT software program in the assessment of jaw cysts and in the differentiation of odontogenic keratocysts and other cysts. MATERIALS AND METHODS: Seventeen patients with proven jaw cysts (8 maxillae & 9 mandibles) were evaluated with a dental CT software program for location, locularity, the presence or absence of marginal scalloping, and height to length ratio. For the delineation of involvement or displacement of neurovascular bundles, cortical erosion, perforation or expansion, and tooth root resorption by the jaw cysts, images from this program were compared to conventional images. RESULTS: Seventeen lesions icomprised 15 odontogenic cysts (five odontogenic keratocysts, five radicular, three residual and two dentigerous cysts) and two non-odontogenic cysts (one nasopalatine duct cyst and one postoperative maxillary cyst). Images of jaw cysts obtained with the dental CT software program delineated much more clearly than conventional images the status of neurovascular bundle and cortical bone, but there was no clear difference between the two modalities in delineating tooth root erosion. Dental CT findings of five mandibular odontogenic keratocysts were scalloped margin in all, mandibular ramus involvement in four, height to length ratio below 60% in four, and multilocularity in two. The findings of the other 12 cysts (eight maxillae and four mandibles) were unilocularity in all, smooth inner margin in ten, height to length ratio below 60% in only two, and ramus involvement in none. CONCLUSION: Adental CT software program is an improved imaging modality for assessing jaw cysts ; and findings which tend to indicate odontogenic keratocysts are marginal scalloping, mandibular ramus involvement, prominent spread along the marrow space and multilocularity.

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.

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.

6.Comparison of clinico-histopathologic findings before and after decompression of odontogenic cyst in the jaw.
Journal of the Korean Association of Oral and Maxillofacial Surgeons 2005;31(2):150-160
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.

cyst which were managed in the Department of oral and maxillofacial sugery from March 1994 to February 1998 was done. An following results were obtained. 1. Male were involved more than females by cyst in a ratio of 1.95:1 and most of the cases occurred in the secondary decades. 2. The primary site of radicular cysts were the anterior incisor area, dentigerous cysts were anterior incisor area and canine area, incisive canal cysts were maxillary anterior area, odontogenic keratocyst were the mandibular ramus area. The common symptoms were swelling(65 cases), pain(12 cases) and the mean duration of syptomatic period was 10 days. 4. The rates of histopathologic classification were radicular cyst(58%), dentigerous cyst(22%), incisive canal cyst(9%), odontogenic keratocyst(11%). 5. Average of Alk. phosphatase was 235(IU/L) at pre-twenty age and 102(IU/L) at post-twenty age. 6. In treatment modalities, enucleation was most common, odontogenic keratocyst was treated by enucleation and curettage for prevention of recurrence.]]>

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.

bone grafts of the jaw. Autogenous particulated bone with osteogenesis and osteoinductive properties and xenogenic Bio-Oss(R) (Geistlich Pharma AG, Wolhusen, Switzerland) graft materials with osteoconductive propertes were grafted into cystic cavities that remained after multiple cystic enucleation in the right upper posterior maxilla and the left lower posterior mandible. Six months later, increased radiopacity in the grafted area was seen. Three-year follow-up results with clinical and panoramic radiography after autogenous and xenogenic bony mixtures in jaw are reviewed and discussed.]]>

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.]]>
