OBJECTIVETo evaluate the symmetry rate of nasal floor width and the influencing factor for the unilateral complete cleft lip (UCCL) after repair with Huaxi technique.

METHODS27 UCCL patients repaired with Huaxi technique were photographed before repair, 1 week and 1 year after surgery. The distance from columella point to facial midline, the nasal floor width and the fissure width were measured. The approach rate of the columella point, the symmetry rate and the change of the nasal floor width were calculated. The statistical analysis was completed by SPSS 13.0.

RESULTSThere was statistical difference of the approach rate for the columella point between 1 week and 1 year after surgery (54.06%, 63.96%; P < 0.05), no statistical difference was found of the symmetry rate for the nasal floor between 1 week and 1 year after surgery (69.12%, 75.93%; P > 0.05). There was statistical difference of the change for nasal floor width between the cleft side and the non-cleft side in a week (P = 0.000), but no statistical difference was found in a year (P = 0.262). The linear correlation was obtained between the distance from columella point to facial midline 1 week after surgery and the distance from columella point to facial midline (r = 0.465, P = -0.014) and the fissure width (r = 0.486, P = 0.010) before surgery. No linear correlation was obtained between other index after surgery and before surgery (P > 0.05).

CONCLUSIONThe symmetry rate of nasal floor width is stable after surgery with Huaxi technique, and the growth changes have not significant impact on the effect of the surgery in a short-term.

This 37 year-old male patient underwent high resolution CT imaging of the face including paranasal sinuses following trauma. Computed tomography (CT) has a well-established role in the assessment of the facial bones in the context of trauma, in particular for fractures involving the paranasal sinuses and orbit. High resolution imaging permits isotropic reconstruction in multiple planes. Its use in imaging the contents of orbit itself is more select, with both direct clinical examination and even orbital ultrasound used to assess the globe and lens of the eye.1 Traumatic dislocation of the lens of the eye may entail the partial or complete translocation of the lens from its normal position within the anterior aspect of the eye.2 The high attenuation lens ‘floats’, within the vitreous of the globe (Figures 1, 2 and 3). Following trauma to the face the injuries may be multiple and cross sub-speciality boundaries, but one should be alert to all injuries. In reviewing CT images one should be forensic in the review of all the anatomy covered, even it is not related to the original clinical query or not pertinent to one’s own clinical speciality. As an old mentor once told me, ‘Before you take the film down, have one last paranoid look.’ Learning Point: Always review the entirety of the imaging performed despite the focus of one’s clinical or speciality interest.

OBJECTIVETo investigate the facial aging analysis of 1200 Han adult people in Dalian with iris diameter, so as to provide reference for facial rejuvenation in Han people.

METHODS1200 facial digital photographs from the second-generation ID card of China were stratified randomly selected as the research sample, excluding facial deformity, tattooing eyebrow, tattooing lid margin, ptosis, lip grain and eyebrow deformity cases, as well as the cases whose join point of upper eyelid and lower eyelid not exposed at the nasal side. These photos were divided into six cohorts: female aged 18, 38, and 68 years old; and male aged 18, 38, and 68 years old, with 200 cases in each cohort. The individual iris diameter was divided into 20 equal parts in each photograph, with each part marked one unit as individual iris diameter ruler. Ten values were made from a horizontal plane between the medial canthus to ten points at one face ( the line between two medial canthus is used as the horizontal line, circumocular and facial soft tissue were measured with individual iris diameter ruler on the photographs), then the results were analyzed with Adobe Photoshop software.

RESULTSThere are statistically significant differences in eyebrow height (36.42 ± 4.22 unit in 18 years old male group, 40.22 ± 6.90 unit in 38 years old male group, 34.83 ± 9.39 unit in 68 years old male group; 37.59 ± 6.72 unit in 18 years old female group, 41.09 ± 5.15 unit in 38 years old female group, 36.84 ± 9.45 unit in 68 years old female group), palpebral fissure height, physiognomic external canthus height, palpebral fissure width, pupil height and other items (P < 0.05).

CONCLUSIONS(1) The brow position rises to the peak level at middle age (38 years old group), then drops down gradually with aging. (2) The physiognomic external canthus moves towards the nasal side and caudal side with aging. (3) Eyeball moves towards caudal side with aging. (4) The soft tissue around bilateral angle of mouth, nasal tip and submaxilla moves towards caudal side with aging. (5) The measurement of individual iris diameter ruler can apply to analyze the aging changes of facial soft tissue, and is more suitable for the case when facial photographs are taken at different distances.

OBJECTIVETo study the influence of nasolabial angle alteration on facial profile attractiveness and investigate the perception differences in profile attractiveness among laypeople.

METHODSA young Chinese female with normal hard and soft tissue cephalometric values was chosen as a research object. Profile photograph was taken in a natural head position. Photoshop software was chosen to rotate the nose tip and upper lip, thus changing the degree and direction of nasolabial angle. A total of 33 different profile pictures were achieved. Thirty-three professional orthodontists and 64 non-professionals were chosen to score these 33 pictures.

RESULTSWhen the upper lip position was fixed, the profile was considerably attractive because the angle of nasal tip was not changed or altered. When the nasal tip rotation angle was fixed, profiles with a retroclined upper lip were considered significantly attractive by the layperson and professional groups. Regardless of the direction of the nasal tip rotation, the respondents considered the profile with a retroclined upper lip highly attractive.

CONCLUSIONThe soft tissue profile with a retroclined upper lip looks considerably attractive in Chinese female populations. Therefore, during an orthodontic treatment, appropriate retraction of the incisor is recommended to improve soft tissue profile attractiveness.

OBJECTIVE: To study the visual sensitivity threshold of physician's naked eye to the difference of nasolabial angle in edentulous jaw patients, and to provide a reference value for the study of aesthetic evaluation of soft tissue profile for the difference of nasolabial angle that can be recognized by human eyes. METHODS: Three-dimensional facial images of three edentulous patients with different diagnostic dentures introoral were obtained. Lateral screenshots of each patient's three-dimensional facial image with the same scale were obtained by using reverse engineering software (Geomagic studio 2014).The screenshot of the patient's three-dimensional facial image with suitable lip support (The suitable lip support was confirmed by both patients and prosthodontists who had clinical experience for more than 20 years) was taken as the reference picture, and the remaining pictures were grouped with it respectively. All the pictures were observed in random order by the subjects. Fifteen dentists were asked to judge the difference of nasolabial angle between the two pictures of each group on the computer screen. The difference of nasolabial angle between the two pictures in each group was measured and calculated. The ROC curve was drawn, and the best cut-off value was calculated as the visual sensitivity threshold. RESULTS: The data of the 15 subjects were used to draw ROC curves separately. The maximum and minimum best cut-off values were 5.55 degrees and 3.12 degrees respectively. The ROC curve of the whole 15 subjects was drawn after data aggregation, and the best cut-off value was 5.36 degrees (AUC=0.84>0.5, P=0.000<0.05). When the difference of nasolabial angle was above 5.36 degrees, the subjects could recognize it effectively. CONCLUSION There is a visual limit in the observation of the nasolabial angle with the naked eye. In this study, a visual sensitivity threshold of 5.36 degrees for the difference of the nasolabial angle was obtained. The difference of nasolabial angle below this value can be regarded as no clinical significance. This result provides a reference value for human eyes to recognize the difference of nasolabial angle in soft tissue profile aesthetic evaluation. It can be applied to the aesthetic evaluation of soft tissue profile and can be used as the error level of related research with nasolabial angle as an index for accuracy evaluation.

To explore the proportion for facial aesthetics that may be recognized by the potential group who will do plastic surgery in the future. 
 Methods: We measured the celebrity photos, who were born before 1980 recognizable by the people over 40 years old or by high school students. The proportions for facial aesthetics recognizable by these two generations were obtained and compared. 
 Results: Compared the new generation of male celebrities with the older generation of male celebrities, the difference was statistically significant by the independent samples t test (t=-2.502, P<0.05), while other ratios were not statistically significant (P>0.05). Compared the new generation of female celebrities with the older generation of female celebrities, the difference was statistically significant by the independent samples t test. The ratios between inter-canthic diameter and eyeslit breadth, mouth breadth and eyeslit breadth, stirnhohe and 1/3 of the physiognomic facial height, nasal height and 1/3 of the physiognomic facial height were significantly different (P<0.05), while other ratios were not significantly different (P>0.05).
 Conclusion: The young new generation loves more larger eyeslit breadth for men, while a larger eyeslit breadth, smaller bizygomatic breadth and sharper chin for women.

A new method using the ideal mid-facial line as the navigating reference was introduced to improve the outcome of cleft lip repair. Using the verticle coordinate crossing the middle point of the intercanthus line, surgeons could observe and correct the distortion of the fine structures in labial-nasal area. This laser projecting mid-facial-line navigation was repeatable, while not interfere the operating. In conclusion, generalizing laser navigation is a valuable supplementary for cleft lip repair.

OBJECTIVE: To establish a series of three-dimensional measurement methods of nasolabial soft tissue for maxillary protrusion patients by using 3dMD camera, and to evaluate preoperative and postoperative changes of the nasolabial soft tissue. METHODS: Three-dimensional facial photos of 30 female patients with maxillary protrusion [average age, (27.33±2.54) years] were taken by 3dMD camera preoperatively and at the end of postoperative 6 months or more. Then, 3dMD patient software was used to locate the selected landmarks at nasolabial region on the three-dimensional photos. Ten measurements, including soft tissue line distance, angle, curve distance and postoperative three-dimensional volume changes were measured twice with one week interval by 3 investigators, respectively. A standard consistency test calculated by the correlation coefficients (ICC) was performed between two sets of data (including all of the 10 measurements) for each investigator and among the three investigators to verify the repeatability. RESULTS: The average maxillary incisor retraction distance of the 30 subjects was (5.13±0.99) mm, and the average follow-up time was (11.07±5.11) months. The standard consistency test was performed between the two sets of data for each investigator, and the correlation coefficients (ICC) of the 10 measurements were all over 0.8 for each investigator (P>0.05). The standard consistency test was performed among the three surveyors, with the result that the ICC of the width of the bilateral inner canthus, the height of the nose, the height of nasal tip, nasolabial angle, philtrum length, the curve height of upper vermilion and the height of upper lip were greater than 0.8 (P>0.05), and the ICC of the distance between SbalSbal, length of nasal dorsum and three-dimensional volume change of upper lip were 0.680, 0.627 and 0.528, respectively (P>0.05). CONCLUSION 3dMD camera and 3dMD patient software can be used to measure and analyze the three-dimensional morphology of the nasolabial soft tissue for patients with maxillary protrusion preoperatively and postoperatively, and it is relatively accurate and reliable. However, the repeatability of three-dimensional positioning of the nasal tip point and the Sbal is slightly worse resulting in the lower value of the ICC of the distance between SbalSbal and length of nasal dorsum, as well as the upper lip three-dimensional volume change after the operation.
