Application of an effective model in intraoral facial skeletal contour surgeries / 中华整形外科杂志

Intraoral facial contour surgery is one of the most popular craniofacial cosmetic surgeries in China, in spite of its challenging surgical technique and serious complication, such as fracture and bleeding. In addition, the key point, such as inadequate tissue exposure and high soft tissue tension cannot be simulated using traditional three-dimensional model. Consequently, craniomaxillofacial surgery requires a long learning curve for young surgeons. This article describes the establishment and application of a new model for intraoral facial contour surgery. Compared to young surgeons trained using traditional three-dimensional model, the authors confirmed this new surgical model is more reliable and effective. Therefore, it is worthy of being popularized.

"Comparison of mandibular angle morphometry between the ""beautiful face"" and ordinary face of young Han women" / 中华医学美学美容杂志

Objective To analyze the difference of soft and hard tissues between beautiful face and ordinary face in young Han women for providing data basis for modification of lower facial contour.Methods 38 cases of young Han women were selected with craniofacial spiral CT scanning,three-dimensional reconstruction and histomorphometry of the mandibular angle region (12 cases of beautiful face and 26 cases of ordinary face).Results The difference of bony bigonial breadth,lower face width,angle of mandibular angle,mandibular branch width and height,the distance between the mandibular angle point and pogonion in mandibular angle region had statistical significance (P ＜ 0.05);the difference of mandibular angle thickness had no statistical significance (P＞0.05);the difference of masseter muscle length,width and thickness had statistical significance (P ＜ 0.05).Conclusions In clinical lower facial contour modification practice,we can refer to the data of soft and hard tissue of mandibular angle region of beautiful face,combining with the specific circumstances of the pursuit of beautiful people and select the appropriate surgical approach for lower facial contour modification.

The study of prevention the gustatory sweating syndrome and facial contour deformity with sternocleidomastoid muscle flaps in the parotidectomy / 临床耳鼻咽喉头颈外科杂志

Objective:To assess the outcome for prevention the gustatory sweating syndrome and facial contour deformity with sternocleidomastoid muscle flaps in the parotidectomy. Method:It was a prospective study. Eighty-one patients who underwent parotidectomy were randomly divided into 2 groups, sternocleidomastoid muscle flaps group and control group. They were tested with the subjective and objective function testing in 3, 6, 9, 12 months after operation. We assessed the result. Result:All of the result of the sternocleidomastoid muscle flaps group was obviously better than the control group. There was significant difference between the 2 groups (P<0.05). Conclusion:It effectively prevented the gustatory sweating syndrome and facial contour deformity that we used the sternocleidomastoid muscle flaps to fill the cavity in the parotidectomy.

Esthetic perception towards different combinations of facial contours and upper incisor shape

Aim: The aim of this study was to assess the esthetic perception of adults with primary, secondary and higher education and recent dental graduates towards different combinations of facial contours and upper central incisor shapes. Methods: Photographs of 6 individuals with square, tapered and ovoid facial contours (2 per type) were modified to have the 3 different types of tooth shapes (square, tapered and ovoid) in each facial contour (total of 18 photographs). The 195 participants rated each photograph using visual analogue scales. Comparison between groups was performed using the Chi-square t-test ('alfa'=0.05). Results: No statistically significant differences (p>0.05) were found in the esthetic perception towards the frontal facial outline and upper incisor shape by participants’ educational level. In addition, the shapes of teeth perceived as the most esthetically pleasing were not always similar to the form of frontal facial outline evaluated. Conclusions: No general agreement was found in the esthetic perception towards the frontalfacial outline and upper incisor shape by educational level. Dentists tend to prefer ovoid shape tooth for almost all frontal facial outline.

Soft Tissue Facial Contouring Using Autologous Microfat Injection

Autologous fat injection had not gained an attention in aesthetic plastic surgery, because of high reabsorption. Recently, fatty tissue was obtained by the low-power technique and centrifuged, results of autologous fat injection was improved. The authors performed autologous microfat injections on 277 patients from March 1997 through December 2002 to correct soft tissue facial contour such as aging, depressed facial contour, thin and long faces as well as postoperative complications and scars. The fatty tissues remaining from the first injection were kept at -20 degrees C up to twelve months, and were used for repeated injections in the overly- absorbed or inadequate areas. Of those 277 patients, 59% received an injection once, 35% received an injection twice, 5% received an injection three times and 1% received an injection up to four times. Follow-ups and postoperative photo confirmations were possible only in 119 out of 277 cases. 81.5% showed satisfied results, and development of complications were insignificant occurring at 6.2%. Owing to advances in tissue engineering and frozen storage method, autologous microfat used for injection will be developed as a better filler, which may substitute soft tissues.
