Objective To explore a method for repairing moderate or severe full defect of lip. Methods One composite lip flap pedicled with lip artery was designed at one side of the defect. If the area of defect was too large, two flaps beside the defect should be designed, and one of two flaps could be extended to lower or upper lip at the angle of mouth to form the large composite lip flap which included the part of another lower or upper lip. The blood supply of this flap came from another...

Objective To explore a method for repairing moderate or severe full defect of lip. Methods One composite lip flap pedicled with lip artery was designed at one side of the defect. If the area of defect was too large, two flaps beside the defect should be designed, and one of two flaps could be extended to lower or upper lip at the angle of mouth to form the large composite lip flap which included the part of another lower or upper lip. The blood supply of this flap came from another side lower or upper lip artery, so it could not be necrotic. The flaps were cut along the design line and propelled to repair the defect. If one flap included the part of another lower or upper lip, the facial artery was ligated and cut at the branching point of upper and low lip artery, so as to increase the movement of the flap. First the oris orbicularis muscles were sutured, then the lip mucosa and skin were sutured separately. If the defect was located at vermilion, the flaps should be designed and cut along the vermilion boundary. Results This method was used in 67 cases, in which 38 cases were the upper lip defect and 29 cases were the lower lip defect. 20 cases were repaired by vermilion flaps and 47 cases by composite flaps which included vermilion and white lip. 10 cases were repaired by one flap and 57 cases by two flaps. The biggest width of the defect was 3.5 cm and the smallest was 1.2 cm. All the flaps survived. The repaired lip was plump and the postoperative appearance of the lip was satisfactory. Conclusions The lip artery is constant. The blood supply of the flap is reliable and anatomizing the flap is easy. The lip defect is repaired with the same tissue, so the lip's shape and functions can be recovered completely. This procedure can be widely used in repairing vermilion and white defect. It is an idea method for repairing moderate or severe full lip defect.

目的 探讨中、重度全层唇缺损的修复方法。方法 在缺损一侧或两侧(若缺损较大,一侧唇瓣不够用时)设计以唇动脉为蒂的唇瓣向缺损区推进转移修复全层唇缺损。若缺损较大,单纯用缺损两侧口唇组织仍不足以修复时,可将一侧唇瓣向外侧延伸绕过口角至另一侧上或下唇(根据缺损是在下唇或上唇),形成包括上下唇组织在内的大型唇瓣向缺损区推进修复缺损。若缺损为单纯的红唇缺损,唇瓣切口应沿唇弓设计。结果 临床应用于67 例,其中上唇 38 例,下唇 29 例。缺损最大水平宽度3.5 cm,最小1.6 cm。单纯红唇瓣20例,红白唇瓣47例。单侧唇瓣10例,双侧57例。所有唇瓣均全部存活,伤口Ⅰ期愈合,修复后的口唇丰满,外形满意。结论 唇动脉血管恒定,唇瓣血供可靠,本法不仅能用于单纯红唇缺损的修复,还可广泛用于红、白唇同时缺损的修复,因是用同类组织修复,且组织量丰富,故术后能完全恢复口唇所特有的红、白唇结构及功能,是修复中、重度全层唇缺损的理想方法。

In accordance with the characters of the well-regulated texture, a method of the label co-occurrence matrix (LCM) was proposed to depict the textural features and discriminate the defects from the normal texture.

In accordance with the characters of the well-regulated texture, a method of the label co-occurrence matrix (LCM) was proposed to depict the textural features and discriminate the defects from the normal texture. The traditional gray-level co-occurrence matrix (GLCM) was computationally intensive and discriminatively insufficient. The proposed method of LCM was ameliorated mainly from computational load and discriminability. In LCM algorithm, some basic textural features were acquired initially to fix some key parameters of LCM, such as the probability density distribution of the texture, dominant orientation and periodicity of the texture, classification regulations, and etc. LCMs were computed and some simple features such as white defect emphasis, black defect emphasis and consistency were extracted from those LCMs. The outlier detection for those features was applied to detect textural defects. Experiments proved that the method was characterized by less computation and better discriminability in comparison with the existing GLCM.

根据有规则纹理的特点,提出了基于类别的共生矩阵来描述纹理特征,从而很好地将正常纹理与疵点区分开.分析了传统的灰度共生矩阵在计算纹理特征时计算量大,且分辨能力差的缺点.为了克服灰度共生矩阵在计算量和分辨能力上的缺点,定义了类别共生矩阵.在类别共生矩阵的算法中,首先学习纹理的一些基本特征以确定类别共生矩阵的一些关键参数,如纹理的概率密度分布、纹理的主方向和周期,以及分类准则等重要参数,然后计算类别共生矩阵并提取白疵点增强、黑疵点增强和一致度等三个特征,最后采用异常点检测的方法即可很好地区分正常纹理和疵点.实验证明,该方法比已有的灰度共生矩阵计算量小,并具有更突出的分辨纹理和疵点的能力.
