After the failure of a composite graft in a patient with complete auricle amputation, we successfully reconstructed the severely gashed auricle using two-stage cartilage preservation surgery. We removed the skin of the amputee and buried the cartilage under the postauricular scalp. The end of the right ear was sutured to the postauricular scalp. A separation surgery was performed on the 14th day after the burying surgery. After removing the suture, the cartilage along with the postauricular scalp was carefully separated from the postauricular donor site under local anesthesia. Using two-stage cartilage preservation surgery, we successfully reconstructed the severely gashed auricle and achieved cosmetically and functionally satisfactory results.

Purpose:
This clinical study presented the effectiveness of 2-stage posterior maxillary segmental osteotomy (PMSO) under local anesthesia in gaining interarch space to restore the posterior mandibular segment with dental implants.
Materials and Methods:
Nine patients who received two-stage PMSO for mandibular implant placement from 2003 to 2011 were included in the study. Of the 9 patients, 7 were female and 2 were male. Ages ranged form 28 to 72 (mean 46.6). Potential complications were investigated such as sinus infection, survival of bone segment, inflammatory root resorption of adjacent teeth, relapse of bone segment and timing of implant placement, delivery of implant prosthesis and stability of bone segment.Result: None of the patients showed relapse or complication. Bone segments were stabilized by opposed implant prosthesis.
Conclusion
Office-based 2-stage PMSO under local anesthesia can be considered a stable and predictable procedure. Also pedicle damage can be avoided by allowing favor of blood supply to the bone segments. From these advantages, it can be concluded that this surgical procedure can decrease post-operative complications.
