A cystic mass of the neck causing neonatal respiratory distress is usually cystic hygroma. A branchial cleft cyst, however, also can cause respiratory distress on rare cases. The fourth branchial cleft cyst is very rare entity and, until now, only 35 cases have been reported worldwide. There have been some controversial attempts to prove its anatomical route through embryological background. Some reports, however, even suggested that it might be impossible to prove its entity anatomically. Recently, reports are coming out on the diagnostic approaches using not only anatomical pathway but also pathological impression. Authors experienced in neonates two cases of lateral cystic neck mass which were pathologically presumed to be fourth branchial cleft cyst. We are reporting these two cases with their diagnostic basis and the related literature.

cyst (BOC) is considered a rare multilocular variant of the lateral periodontal cyst. In this report, a 67-year-old male visited with chief complaint of severe mobility on mandibular incisors. Multilocular radiolucent lesion was seen from the right premolar to the left premolar area, involving almost the whole mandible. Histologically, the botryoid odontogenic cyst showed focal nodular thickening of the lining epithelium. These thickening often showed swirling appearance of the cells. Cyst enucleation and bone graft on mandible anterior and both body area were performed under general anesthesia, and postoperative healing was favorable without recurrence.]]>

cyst. This report focuses on a case in which a solitary lateral neck mass was the sole initial presentation and clinically exhibited the usual appearance of brancheal cleft cyst. Accordingly, it is suggested that, in patients presenting with an asymptomatic solitary lateral cystic neck mass, the possibility of metastasis from an occult thyroid cancer should be considered and consent for definitive surgery should be obtained.]]>

PURPOSE: To assess the radiographic findings of odontogenic cysts showing displacement of the mandibular canal using computed tomographic (CT) and panoramic images. MATERIALS AND METHODS: CT and panoramic images of 63 odontogenic cysts (27 dentigerous, 16 odontogenic keratocysts, and 20 radicular cysts) were analyzed to evaluate the following parameters: the dimension and shape of the cysts, and the effect of the cysts on the mandibular canal and cortical plates. RESULTS: Of the 63 cysts examined in the study, 35 (55.6%) showed inferior displacement of the mandibular canal and 46 (73.0%) showed perforation of the canal. There were statistically significant differences between CT and panoramic images in depicting displacement and perforation of the mandibular canal. Cortical expansion was seen in 46 cases (73.0%) and cortical perforation in 23 cases (36.5%). The radicular cysts showed cortical expansion and perforation less frequently than the other cyst groups. CONCLUSION: Large cysts of mandible should be evaluated by multiplanar CT images in order to detect the mandibular canal and cortical bone involvement.

Radicular cyst is the most common odontogenic cyst occurring in the jaws. The cyst is commonly found in relation to the maxillary anterior teeth in the third and fifth decade of life. Although multiple radicular cysts are not uncommon in the jaws, bilaterally symmetrical representation of these cysts is rare. Radiographs prior to extraction help in diagnosis of these cysts and thereby prevent further morbidities. We report a case of 16-year-old male patient who presented bilateral radicular cysts symmetrically in the mandible.

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.

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.

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.]]>

radicular cyst and dentigerous cyst were most common cysts, irrespective of 73 cases(48.3%) and 35 cases(23.2%). 4. The frequently involved cystic regions were followed as mandibular molars(38.1%), and maxillary incisors(30.2%). 5. The frequent sequence of clinical symptoms was edema(29.9%), no symptom(18.9%), tenderness(13.9%), pain(11.5%) and abscess(9.4%). 6. The most prevalent treatment was the combination operation, such as cyst enucleation with extraction or endodontic treatment of the causative tooth(76.8%) 7. Among 155 cases, 2 cases that were treated using enucleation method were recurred(1.3%).]]>
