In children, large odontogenic cysts affect adjacent anatomical structures as well as displace developing permanent teeth. Odontogenic cysts are treated via enucleation or marsupialization. This case reports a 5-year-old boy and a 10-year-old boy who have not only displaced 3 or more permanent teeth but also elevated the maxillary sinus floor due to the large size of the cyst in the maxillary anterior region. In both cases, marsupialization was selected to minimize complications. After marsupialization, a customized acrylic obturator, window opening, and orthodontic traction for eruption guidance were gradually attempted, and it showed a good prognosis, so we report these cases.

Authors was experienced a case of mucocele in the left frontal sinus. A 24-years-old Korean male soldier was admitted to C.A.F.G.H. on 16th May 1980, with chief complaints of dull headache, exophthalmos, visual disturbance and intermittent epistaxis on the left side. On physical examination, left turbinates and septum were revealed hyperemic middle turbinate with blood tinged spots and deviated slightly to right side, and felt round, smooth, rubbery painless swelling within the orbit at the left inner canthus. The left orbital contents was displaced laterally producing proptosis with diplopia. On the radiological examination, Caldwell and Water's view showed hazy density in medial side of left orbital and left frontal sinus. Tomography of orbit showed hazy increased mass density with rather sharply defined outer margin of left bony orbit probably due to compressive erosion. The case was treated with surgical removal of the Lynch frontal approach, so present this case with a brief review of the literature.

Congenital epiglottic cyst is rare cause of stridor in neonate and if managed inadequately, disaster such as death can occur. Diagnosis of congenital epiglottic cyst includes imaging studies and endoscopy. Fiberoptic or rigid endoscopic examination excludes other causes of stridor in neonate. Complete excision of cyst is treatment of choice under suspension laryngoscopic guidance. Here, we report a case of congenital epiglottic cyst and concomitant laryngomalacia presenting with seizure and respiratory difficulty in neonate with a review of literature.

Esophageal duplication cysts are uncommon, benign lesions of the esophagus. They are rare congenital foregut anomalies. To be considered an esophageal duplication cyst, a lesion must meet the following criteria:1 the cyst in the esophageal wall 2 the cyst is covered with a muscularis propria,generally of two layers and 3 the cyst has an epithelial lining consistent with that of the 4 week embryo, which may be columnar or pseudostratified columnar, and may be ciliated. Herein we report a case of an esophageal cyst located within the thoracic cavity, which is, to the best of our knowledge, the first case reported in Korea. Surgery is generally the treatment of choice for esophageal cyst, and was indicated in this case for the diagnosis and management of symptoms attributable to the cyst.

Branchial cleft cysts are most common neck masses in adults. Most are second branchial cysts, which occur in the neck, anterior to sternocleidomastoid muscle at the mandibular angle. Rarely these cysts may be present in the parapharyngeal space. We report a case of a second branchial cleft cysts in the parapharyngeal space of 32-year-old female, which was misdiagnosed as peritonsillar abscess. It was excised via transoral and transcervical approach.

Cystic lesions of the neck are frequently encountered on clinical basis. The usual differential diagnosis includes branchial cleft, cystic hygroma, dermoid cyst, tuberculous lymphadenitis, benign detached goiterous thyroid cyst, and Cavitation epidermoid carcinoma. Most of cysts are benign and malignant cysts are rare. The most common form of cystic malignancy in the lateral neck is cystic degeneration of epidermoid carcinoma metastatic to cervical lymph nodes. Cystic neoplasia may result from malingnant changes occurring within the wall of a previously benign cyst Complete head and neck examination on the primary focus is important Especially, when palpation of thyroid is negative, thyroid carcinoma is easily overlooked. Recently, we experienced papillary carcinoma of the thyroid seen as lateral neck cyst. So we report this case with review of literatures.

Epiglottic cysts cause stridor mimicking asthma and hinder intubation in surgery. A huge cyst can obstruct the airway, making laryngeal examinations impossible. Before surgery, complete visualization of the larynx is necessary for the successful excision of a cyst. If laryngeal examination fails, computed tomography (CT) scanning can provide detailed information. Virtual endoscopy based on CT data reconstruction can yield a detailed three-dimensional image of the larynx. Here, we report two cases of epiglottic cysts along with virtual endoscopic findings and surgical photographs.

Epidermal cyst in the floor of mouth is relatively rare disease. Patients usually present soft and non-tender mass at the midline of mouth floor. Careful history taking and imaging study are needed for the diagnosis and surgical excision is the choice of treatment. We report a case of huge epidermal cyst located in the floor of mouth mimicking plunging ranula, which was successfully removed by transoral surgical excision without any complication. It was diagnosed as an epidermal cyst by pathologic examination.

Ectopic thyroid gland is a defined as thyroid tissue located in a site other than its usual pre-tracheal location. Ultrasound examination, CT scan, thyroid scan, and thyroid iodine uptake test are all valuable modalities for a differential diagnosis. Although most of cases are asymptomatic, treatment is indicated when there are symptoms related to progressive growth of mass. This article reports a ectopic thyroid cyst in the anterior neck that was similar to deep neck infection accompanied by acute airway obstruction.

Odontogenic keratocyst is a central destructive lesion of the jaws characterized by a thin, fragile layer of orthokeratinizing or parakeratinizing stratified squamous epithelium. Correlation between the histologic type and the recurrence ratio remains a subject of controversy, and multiple cysts are known to be associated with the nevoid basal cell syndrome. We experienced a case of multiple odontogenic keratocyst in a 25 year-old male patient involving bilateral mandible and maxilla. The cystic mass of the right maxilla was removed by Caldwell-Luc's approach and the right mandibular mass was removed by intraoral approach but the teeth that were impacted in the mandibular bone were remained in order to prevent an iatrogenic fracture.
