High septal deformities exert pressure on upper lateral cartilages and nasal bones and cause external deviation of the nose. However, detection of high septal deformities causing deviated noses is very difficult if a detailed intranasal examination is not performed. As well, the high septal border is a difficult area to approach via the endonasal rhinoplasty and is the weakest portion in the septum resulting in much difficulty in correcting deformities and in frequent later recurrence of deviation secondary to the healing process. In order to solve the above problems in 33 cases of deviated nose associated with high septal deformities, the authors evaluated deformities in the high septal border after separation of the septum from upper lateral cartilages and nasal bones. The high septal border is centralized by scoring after resection of the mid or lower-septal portion. And spreader grafts were applied to the convex sides of deviated septal borders to stabilize the high septal border and to prevent long-term recurrence of deviation. Also, to balance the traction force of side walls, the length of both upper lateral cartilages and nasal bones were equalized by resection in the longer side and grafting in the shorter side. Clinical follow-up ranged from 3 to 31 months. There was no surgical or septal complication. Also, there was no incomplete correction, recurrence of deviation, or compromized nasal support. All patients except 2 were satisfied with the aesthetic and functional results. We found that separation of septum from side walls allows detection and correction of higher septal deformities and that spreader graft allows long-term support and prevents later recurrence of deviation.

The use of a cultured autologous keratinocyte sheet has become a recognized method for the coverage of extensive bums during recent years. The disadvantages of these sheet grafts are a long time-lag until keratinocyte sheets are available, the fragility and difficulty in handling of grafts, an unpredictable take rate and extremely high costs. In this study we investigated the transplantation of cultured keratinocytes as single cells suspended in autologous fibrin glue. In a rat model with standardized full thickness wounds, this new transplantation technique was evaluated and compared directly to the conventional keratinocyte sheet grafting technique. After transplantation, wounds were evaluated for the degree of epithelial coverage, and then microscopic structures were evaluated under light and electron microscopy. The results were as follows: 1) The fibrinogen solution prepared from autologous blood had 12 times more fibrinogen compared to the original blood. 2) After transplantation of cultured keratinocyt-es in fibrin glue, the degree of epithelial coverage was 79% at 2 weeks, which was comparable to 17% for cultured keratinocyte sheet graft 3) Typical basement membrane structures were consistently found at 2 weeks after transplantation of keratinocytes in fibrin glue. 4) Rete ridges were found at 4 weeks after transplantation of keratinocytes in fibrin glue. In conclusion, the transplantation technique of keratinocytes in fibrin glue is available earlier than sheet grafts, it transfers actively proliferating cells and it simplifies the grafting procedure. As well, this technique leads to an earlier epithelial covering and an earlier restoration of the dermo-epidermal junction than sheet grafting.
