Three-dimensional Quantitative Standards for Assessing Outcomes of Facial Lipotransfer: A Review.

Background: Reliable quantitative data are required to address the unpredictability of facial autologous fat grafting (AFG). Facial evaluation by 3D scanning technology is getting popular. However, this process lacks unified standards and the reliability assessments.

[Clinical study of chest contour deformity after harvesting of costal cartilage for total ear reconstruction].

Objective: To investigate the chest contour deformities after harvesting of costal cartilage for total ear reconstruction, so as to prevent donor site morbidity.

Methods: 107 cases of microtia who underwent ear reconstruction with costal cartilage during the period from 1994 to 2003, were retrospectively studied. Both the chest depression deformity and the costal arch deformity were evaluated.

[Biomechanical properties of the costal cartilage and its significance in the timing of ear reconstruction].

Objective: To investigate the age-related change in biomechanical properties of the costal cartilage and its relevance to the timing of ear reconstruction with costal cartilage framework.

Methods: The patients of 5 to 25 years old were divided into three groups according to their age. The biomechanical properties of costal cartilage harvested from these patients during ear reconstruction were tested, including stree-strain relationship, stress relaxation and creep, tensile strength.

[Application of residual ear in auricular reconstruction of microtia].

Objective: To summarize different treatments of the residual ear in auricular reconstruction, to investigate the reasonable applications of the residual ear.

Methods: From September 2005 to July 2006, 128 patients (79 males, 49 females; aging 5-21 years with an average of 11 years) with unilateral microtia underwent the staged repair. In the patients, there were 44 cases of left-unilaterally microtia and 84 cases of right-unilaterally microtia.

An investigation of psychological profiles and risk factors in congenital microtia patients.

Objectives: Among congenital deformities, microtia is often said to be one of the most difficult for the reconstructive surgeon. However, few reports have investigated patients' and their families' psychological profiles. This study sought to determine the prevalence of mood disorders among patients with microtia and to explore clinical features associated with mood disorders.

[Psychological status of congenital microtia patients and relative influential factors: analysis of 410 cases].

Objective: To investigate the psychologic status of congenital microtia patients and related influential factors.

Methods: In a cross-sectional survey for congenital microtia, 410 patients, 314 males and 96 females, aged 12 +/- 6 (5 - 37), underwent psychological survey with the symptom checklist-90 (SCL-90) or Achenbach child behavior checklist (CBCL), centering on the 3 main psychological problems: depression, interpersonal sensitivity or social difficulties, and hostility or aggression. A questionnaire was designed to investigate the influencing factors, such as the patients' own factors, and psychological factors of the patients' families Chi square test and logistic regression analysis were performed to find the factors contributing to those psychological problems.

[Classification and repairment of "butterfly ear" deformity].

Objective: To classify and repair "Butterfly Ear" deformity which presents characters of dysplasia of inferior auricle of ear and congenital bat ear.

Method: The repairment procedures include: type I: auricular cartilage flap inversion folding technique. type II: local ear skin flap.

[Case control study on risk factors of congenital microtia].

Objective: To identify the risk factors associated with congenital microtia.

Methods: A case-control, retrospective study was performed. A total of 207 cases of congenital microtia and 209 age-frequently-matched controls were interviewed individually according to the uniform questionnaire.

[Psychologic status and their influencing factors in congenital microtia patients and their families].

Objective: To study the psychologic status and their influencing factors in congenital microtia patients and their families.

Methods: Totally one hundred and two congenital microtia patients (79 men, 23 women, mean age 13.62 +/- 7.
