Purpose: To evaluate the effectiveness of arthroscopic direct cystic removal of popliteal cyst using 70 degree arthroscopy and posteromedial portal. Materials and Methods: From January 2003 to January 2004, 21 patients(23 cases) with popliteal cyst have been treated by direct cystic decompression with arthroscopy. The average age of the 21 patients was 54 years(range 35 to 78 years). There were 5 males and 16 females. Of the 23 cases,8 cases were occured in right side and 11 cases were occured in left side. 4 cases were both sides. In all cases, preoperative MRI were performed to detect combined intraarticular pathology. At 6 months and 1 year postoperatively, follow-up ultrasonography were performed to detect recurrence of cyst. We used Rauschning and Lindgren criteria for clinical evaluation. Results: All cases had no recurrence and no complaints of pain, swelling, or functional impairment at 1 year after surgery. At ultrasonography, no recurrence were founded. One complication was occurred. Postoperatively, Rauschning and Lindgren criteria were more than grade 1. Conclusion: Arthroscopic direct cystic removal using arthroscopy and posteromedial portal is an effective method in popliteal cyst surgery.

Intraspinal neurenteric cyst is rare congenital lesion derived from disorder of notochord formation. Most of these are located ventral to the spinal cord and conventional posterior approach is considered to be effective method as initial treatment modality. This cyst can recur, but the risk of reccurence after partial removal through long term follow-up has not been determined. We experienced one case of cervical neurenteric cyst which recurred after partial removal through laminectomy. The magnetic resonance imaging and postmyelography computerized tomography revealed an intradural extramedullary cystic lesion anterior to the cervical cord at the fifth cervical vertebra level. We performed anterior cervical corpectomy and cyst was totally removed. The patient's neurological symptom was improved postoperatively. Neurenteric cyst located ventrally to the cervical spinal cord should be removed through anterior route for direct visualization of the relationship between the cyst wall and the spinal cord.

Lymphangioma is a benign, growth of lymphatic tissue that is present at birth or develops in early childhood, which may cause serious alterations in growth and developmemt. The problems with facial lymphangioma is usually releated directly to their size and to the area of the face which is involved. The lesions themselves may range from small, localized blemishes to huge facial masses involving both soft tissue and underlying bone and causing great distortion and asymmetry. The facial bones are seldom involved, but the natutal evolution of an individual lesion often cannot be accurately predicted when the child is first seen. Any changes in the underlying facial bone could be due either to a direct growth of the lesion into the bone, or secondary to pressure of the lesion growing outside the bone itself. A case of cystic lymphangioma extending from the neck to the tongue is reported. A six-year-old female was admitted because of swelling of the tongue. At that time, the tongue reportedly reached the extraoral size of 7x5x2.5cm and a soft, diffuse swelling of left anterior neck was revealed. The removal of cystic mass including left neck dissection and partial glossectomy were undertaken. The another case of lymphangioma is located on mandibular cheek. A twenty nine-year-old male was admitted because of palpable mass of the left mandibular area and fissure of palate. The radical excision of mass with mandibulectomy of body were undertuken. Thus we reported such a rare case and reviewed the lymphangioma.
