The dentigerous cysts originate through alteration of the reduced enamel epithelium after amelogenesis is completed, with accumulation of fluid between the layers of the enamel epithelium, or between this epithelium and the tooth crown. Next to the radicular cyst, they are the second most common type of odontogenic cyst. They occur over a wide age range with a peak frequency in the 2nd to 3rd decade. A substantial majority involve the mandibular third molars, followed in order of frequency by the maxillary permanent canines, mandibular second premolars, and maxillary third molars. With regard to the treatment of these cysts, the marsupialization procedure with obturator is recommended during the age when the eruptive force of the teeth is still strong. It can be effective when preservation of the displaced teeth is desirable. We treated the dentigerous cyst by marsupialization with obturator and guided the eruption of involved teeth to normal position. And we got the results as follows : 1. Severely dislocated teeth associated with dentigerous cyst erupted into proper position. 2. The enamel hypoplasia and the root deformity were observed some cases. 3. The bone expansion and defect were healed without infection and recurrence.

The present report describe the surgical therapy, clinical course, orthodontic treatment and morphological characteristics of an adenomatoid odontogenic tumor in the maxilla of an 11-year-old patient. The cystic tumor filled the maxillary sinus and involved a tooth. Marsupialization was accompanied by partial enucleation and applied traction to the affected tooth by a fixed orthodontic appliance. Healing was uneventful and no local recurrence was observed during a 1-year period of follow-up control.

Cystic lesion which is located in vallecular area is sometimes symptomatic and need surgey. But surgical route to this area is divided external approach into internal one. Internal approach via transoral route with suspension laryngoscope can avoid disadvantages of external approach but conventional laryngoscope is not suitable for this type of procedure. We used Steiner laryngopha-ryngoscope in surgery for vallecular cyst and we could excise cyst easily. Of 20 cases, complete excision was tried in 18 cases and marsupialization in 2 cases. Recurrence was 1 case. We suggest that surgery using laryngopharyngoscope is effective in treating cyst which is located in vallecular area.

A cyst is a pathologic lesion characterized by a cavity filled with fluid, celluar products, air, or a combination of these. Dentigerous cysts were formed around the crown of unerupted teeth. The reduced enamel epithelium persists around the crown after it has formed. Proliferation of the epithelium in a fluid-filled sac may be induced by osmotic pressure. In the first decade the most frequent location is the premolar site. In each subsequent decade the largest number of cysts are in the mandibular third molar site, with the second most frequent site being the maxillary canine. The treatment of odontogenic cyst can be mostly classified into three types of cyst enucleation, marsupialization and decompression. We should consider age of patient, anatomic structure, location and size for choosing a treatment method. Advantage of cyst enucleation is fast healing, but a injury of a surrounding structure is highly. Marsupialization is conservative treatment that can reduce the damage of a adjacent structure, but it is only limited at superficial lesion. Decompression also is conservative treatment, but it has the difficulty of the oral hygiene and the troublesome of the lavage. We present the possibility that reduces the defect of decompression and cures the lesion efficiently. We report a male patient with the dentigerous cyst developed at left mandibular third molar in this study. We used the decompression for a treatment and created special appliance to treat the lesion efficiently. We report a case of the cyst treatment that is association with efficiency of decompression appliance.

Odontogenic keratocysts are developmental odontogenic cysts which derived from rests of dental laminas and often found in posterior area of mandible. Because this lesion has tendency of frequent recurrence, treatment of choice is often radical removal of the lesion. Sometimes in case of large cysts, however, conservative therapy like marsupialization is often selected in treatment plan. A 39-years old woman referred to our department for evaluation of large radiolucent lesion that occupies the areas from mandible angle to upper part of ramus and condyle. In cytology, the lesion was identified as odontogenic keratocyst. Marsupialization was our treatment of choice, and the result was so favorable. 2 years later, there was small radiolucent lesion on upper part of mandibular ramus on panoramic view. It was suspected as recurred lesion, and excisional biopsy was done. On biopsy result, it was not a cystic lesion but fibrosis.

A cyst that develops in children's jaw occasionally disturbs the eruption of the succedaneous teeth. These teeth, however, usually have the potential of eruption. So, if the obstacles to eruption are eliminated, it is possible that the teeth erupt spontaneously to their normal position. In those cases, it usually requires the management of the cyst and the eruption guidance of the displaced teeth. Many surgical procedures have been described for the elimination of cysts. When the cyst is large and displaces the permanent teeth, marsupializaion is a surgical technique that may be preferred to enucleation in treatment of cysts. In marsupializaion, if the opening is maintained properly, it may be possible to manage the cyst and guide the displaced teeth into the normal position. In these cases, the cysts were managed with marsupialization in concomittent application of acrylic obturators, and as a result the displaced permanent teeth were guided into normal position. Even though the etiologic factors of the two cases are different, the treatment was the same. And both cases show that the potential for heal ing is remarkable with spontaneous relocation of displaced tooth, provided the opening is maintained during the eruption of the permanent tooth.

The keratocystic odontogenic tumor (KCOT) is a unique cyst because of its locally aggressive behavior, high recurrence rate and characteristic histological appearance. Various options are available for treatment. While some clinicians advocate aggressive forms of dental treatment, others prefer more conservative therapy. In this study, two types of conservative surgical procedures were performed to treat the tumor; marsupialization and cyst enucleation. The patients showed healing process on conservative surgical treatment and teeth erupted without recurrence. Conservative surgical treatment can be an effective treatment option for young children because of their efforts to preserve teeth and other anatomical structures.

Objectives: This study evaluated the clinical results of partial sublingual glandectomy accompanying the excision of ranula as new treatment modality. Materials and Methods: A total of 43 patients who were treated between 1999 and 2007 for oral or plunging ranula were reviewed. All patients were treated surgically by various methods with a total of 55 different procedures performed. Ten cases of partial sublingual glandectomy with excision of the ranula were conducted. All excised specimens were examined. We compared the clinical outcomes resulting from each treatment method. Results: The recurrence rates for marsupialization, excision of ranula, marsupialization with gauze packing, total excision of sublingual gland and ranula, and partial sublingual glandectomy with excision of ranula were 50%, 25%, 25%, 0% and 10%, respectively. Of the 10 patients treated by partial sublingual glandectomy with ranula excision, only one experienced recurrence (10%), i.e., plunging ranula. None of the ranulas contained an epithelial lining, and the excised portion of the feeding sublingual glands showed degenerative changes. Conclusion: In removal of ranulas, we found that excision of the attached sublingual gland, which removed the feeding portion and degenerative acinar cells, yielded good outcomes. Thus, as a new conservative method for treatment, we recommend partial sublingual glandectomy to accompany excision of the ranula.

In the ENT fields, epidermoid cysts occur infrequently in the oral region and often situated on the floor of the mouth or the submental region. Moreover, epidermoid cyst on the laryngeal surface of the epiglottis occurs rarely. Authors experienced a case of epiglottic epidermoid cyst and treated successfully by transhyoid pharyngotomy approach and marsupialization. It was 46 years old male patient who has been suffered from intermittent sorethroat for 2 years prior to admission, hoarseness for 2 months and dyspnea for 1 month. Indirect laryngoscopy revealed a pigeon egg-sized, round, smooth tumor mass on the laryngeal surface of the epiglottis which had soft consistency on digital examination. Biopsy proved epidermoid cyst. Marsupialization of the cyst by transhyoid pharyngotomy approach was performed and the postoperative course was uneventful.
