OBJECTIVE: The purpose of this study was to evaluate the clinical presentation and surgical outcome in patients with symptomatic discal cyst. METHODS: The authors reviewed consequent 9 patients in whom microscopic excision of the discal cyst with or without additional discectomy for discal cyst from 2005 to 2012. Diagnostic imagings including simple radiographs, computed tomography with discogram and magnetic resonance images were performed in each case. The patients were reviewed to evaluate the clinical presentation, surgical outcome and related complications. RESULTS: In all patients, discal cyst was located in the lumbar region and they presented with back pain and unilateral radiating pain. The preoperative magnetic resonance images (MRI) and computed tomography (CT) scan with discogram showed a connection between the cyst and the involved intervertebral disc. All patients obtained immediate relief of symptoms after microscopic excision of discal cyst. There were no recurrent lesions during follow-up period. The mean preoperative visual analogue scale (VAS) was 7.8 when compared with 2.6 in preoperative assessment. All patients obtained excellent or good outcome according to modified MacNab's criteria. CONCLUSION: Discal cysts are rare lesions that can lead to back pain and refractory sciatica. Microscopic excision of the cyst can achieve remarkable improvement of symptoms.

BACKGROUND: Classical guided bone regeneration (GBR) treatments can achieve favorable clinical results for ridge defects. However, extensive bone augmentation in the non-esthetic area in the posterior region for minor ridge defects is unnecessary. Therefore, this study used a collagen and Platelet-rich fibrin (PRF) mixture for bone augmentation on minor posterior ridge defects and evaluated the effects. METHODS: 22 Seibert Class I ridge defects were treated with BC and covered with a PRF membrane (simplified guided bone regeneration, simplified GBR) and other 22 were treated with Bio-Oss and covered with Bio-Gide (classical GBR). Cone-beam computed tomography imaging was conducted 6 months post-surgery to compare the ridge’s horizontal width (HW) and buccal ridge’s horizontal width to assess the osteogenic effect. In addition, the buccal ridge contour morphology was studied and classified. RESULTS: The buccal ridge contour of simplified GBR was Type A in 14 cases, Type B in 7 cases, and Type C in 1 case and it of classical GBR was Type A in 11 cases, Type B in 8 cases, and Type C in 3 cases. The mean HW significantly increased by 1.50 mm of simplified GBR treatment, while it increased by 1.83 mm in classical GBR treatment. CONCLUSION The combined use of BC and PRF had a significant effect on bone augmentation and this treatment exhibited promising clinical results for correcting posterior Seibert Class I ridge defects. The morphological classification of the reconstructive effect in this study can be utilized in future clinical work.
