Background and Objectives : Based on histological findings, intracordal cysts are divided in two subtypes : retention cysts and epidermoid cysts. They are typically located in the superficial layer of the lamina propria and appeared as opaque ovoid buldging masses underlying the epithelium. They are characterized by unilateral diminished mucosal wave on stroboscopy. In this article, we report some cases of patients with an oval shaped-yellowish flat cyst. Materials and Method : At the clinic of the department of otorhinolaryngology in Gangnam Severance Hospital, with 3 female complained of hoarseness as subjects, using the stroboscopy we checked preoperative and postoperative vocal cord and operative findings. Surgery was performed under general anesthesia by the senior authors. All patients noted subjectively that their performing voice was improved. Results : During surgery, an oval shaped-yellowish flat cystic lesion was distinguished from normal epithelium. On palpation of this area with microforceps and cottons, the yellowish discharge was noted to move out from the opening of the cyst. In one case, the cyst was ruptured but remove the capsule completely. In other cases, sulcus was noted at the oppsite site. Conclusion : Because of the opening, the cyst was not easy to dissect and remove completely. After the debris was move out, fibrosis around the opening and invaginated epithelium extending into the deeper layers to the fold. The cyst was must removed carefully and completely for improvement of voice quality before evolving into a sulcus vocalis.

Some types of spinal dysraphism can be accompanied by extraspinal cysts, including myelomeningocele, myelocystocele, myelocele, meningocele, limited dorsal myeloschisis, lipomyelomeningocele, and terminal myelocystocele. Each disease is classified according to the developmental mechanism, embryologic process, site of occurrence, or internal structure of the extraspinal cyst. In most cystic spinal dysraphisms except meningocele, part of the spinal cord is attached to the cyst dome. Most open spinal dysraphisms pose a risk of infection and require urgent surgical intervention, but when the cyst is accompanied by closed spinal dysraphism, the timing of surgery may vary. However, if the extraspinal cyst grows, it aggravates tethering by pulling the tip of the cord, which is attached to the dome of the cyst. This causes neurological deficits, so urgent surgery is required to release the tethered cord.

Objectives : The study is to report cases of open/closed types of epidermal cyst removed by surgical method with Bufonis Venenum pharmacopuncture. Methods : 2 patients were diagnosed each open/closed epidermal cyst. Local anesthesia was achieved with Bufonis Venenum pharmacopuncture. Incision was made using 15^th blade and the CO₂ Hani-maehwa laser. After cyst was removed, simple interrupted suture was performed. Eunkyo-san and Yeonkyopaedok-san were administered respectively for 7 days for anti-inflammatory effects. Results : Local anesthesia was maintained until epidermal cysts were clearly removed. The suture was removed after confirmation of skin adhesion. Adverse reactions were not reported. Conclusions : Epidermal cysts were removed surgically after Bufonis Venenum pharmacopuncture anesthesia and the risk of infection can be prevented by administering herbal medicines that have anti-inflammatory properties. It is difficult to visually diagnose closed type of epidermal cyst and then suggests that imaging equipment such as ultrasound is required.

Recent studies suggest that most meniscal cysts can be treated surgically by arthroscopic management of the meniscal tear and arthroscopic cyst evacuation. But arthroscopic cyst decompression may sacrifice a substantial amount of meniscal tissue that is not torn in order to expose the "stalk" of the cyst. Nowadays, the trend is changing as preserving the involved meniscus to prevent from inevitable degenerative changes after meniscectomy. The purpose of this report is to describe a new surgical technique that minimizes loss of meniscal tissue in hopes of maximizing residual meniscal function. We experienced 10 patients with meniscal cysts that were consisted of four lateral cysts and six medial cysts. Menisci were torn in all cases. Arthroscopic partial meniscectomy and decompression of cysts were performed in 9 cases, and arthroscopic partial meniscectomy and open cystectomy in 1 case. The procedures were consisted of injection of the methylene blue into the cyst, partial meniscectomy of the meniscal tear until the dye was seen in orifice of the cyst, and decompression of cyst through cystic opening. This article serves to confirm the relationship between torn menisci and cysts, to re-evaluate the occurrence ratio of the meniscal cyst on the medial to lateral meniscus, and to assess the efficacy of arthroscopic partial meniscectomy and decompression of cyst as a potentially meniscal sparing procedure.

The purpose of this report is to describe a treatment method of dentigerous cyst associated with unerupted permanent teeth in mixed dentition patients. In our cases, extraction of infected primary teeth was followed by decompression of the cyst. At the same time, parts of the cystic walls were sent for histopathological examination. Decompression was performed by inserting a rubber tube into the cystic cavity through the extraction socket. The cystic cavity was kept open by means of vigorous use of a syringe by patient. Postoperative panoramic radiograph was taken bimonthly. After $5{\sim}12$ months, the impacted permanent teeth were erupted on the desired position. All cases presented favorable result. By extracting the infected primary teeth, and opening the cyst for continuous drainage, it was possible to achieve spontaneous eruption of the involved permanent teeth into the proper position. In all our cases, there was no sign or symptom of recurrence of the cyst up to postoperative 18 months.

We reported a unique case of posttraumatic giant infratentorial extradural intradiploic epidermoid cyst. A 54-year-old male, with a previous history of an open scalp injury and underlying linear skull fracture in the left occipital region in childhood, presented with a painful subcutaneous swelling, which had been developed gradually in the same region and moderate headache, nausea, vomiting and cerebellar ataxia. The duration of symptoms on admission was 3 months. Imaging studies revealed occipital bone destruction and giant extradural intradiploic lesion. The preoperative diagnosis was giant infratentorial extradural intradiploic epidermoid cyst. Surgery achieved total removal of the lesion, which was histologically confirmed and the postoperative course was uneventful. To our knowledge, this is the first case of giant infratentorial extradural intradiploic epidermoid cyst with a traumatic etiology described in the literature.

The dermoid cyst is the one of common space occupying orbital lesion. This lesion is regarded as a non-invasive tumor, but infrequently causes destruction of adjacent bony structure and displacement of adjacent tissue. We experienced a characteristic ovoid orbital dermoid cyst that occupied in the frontal sinus and causes displacement of the eyeball with well-defined lining. This 55-year-old male presented a mass in left orbit, which rapidly increased in size for past 12 months, and patient could not open left eyelid. We removed this tumor totally then reconstructed the orbital roof and frontal sinus with an iliac bone graft and polyethylene sheet(Medpor Newnan, USA). This patient was followed up for 12 months and patient obtained satisfactory result without any complication suck as recurrence or infection.

A 19-month-old boy suffered from stridor and dysphagia. He was taking asthma medication for a few months, but symptoms did not improve. After admission, a chest CT showed a posterior mediastinal mass, which compressed the trachea and esophagus. The removed mass via open thoracotomy was a bronchogenic cyst on histopathology. Postoperatively, stridor and dysphagia disappeared. In case of persistent and refractory stridor or dysphagia in children, congenital lesions including bronchogenic cyst need to be ruled out.

Although discal cysts are a rare cause of low back pain and radiculopathy. Currently, surgical excision is usually the first-line treatment for discal cysts. However, alternative treatment methods have been suggested, as in some cases symptoms have improved with interventional therapies. A 27-year-old man presented with an acute onset of severe pain, and was found to have a discal cyst after an open discectomy. The patient underwent cyst aspiration and steroid injection through the facet joint under C-arm guidance. After the procedure, the patient's pain improved to NRS 0-1. On outpatient physical examination 1 week, and 1 and 3 months later, no abnormal neurological symptoms were present, and pain did not persist; thus, follow-up observation was terminated. When a discal cyst is diagnosed, it is more appropriate to consider interventional management instead of surgery as a first-line treatment, while planning for surgical resection if the symptoms do not improve or accompanying neurologic deficits progress.
