ObjectiveTo study the effectiveness of facial meticulous fat grafting by fat granules injection asistor.
MethodsBetween January and August 2015, 46 patients received facial autologous fat grafting for rejuvenation. There were 7 males and 39 females, aged 21-65 years (mean, 34 years). Firstly, the faces were divided into 10 cosmetic zonations according to facial aesthetic criteria, then autologous fat grafting was carried out by fat granules injection asistor. The autologous fat was filled into 1, 2, 3, 4, 5, 6, 7, 8, and 9 cosmetic zonations in 3, 7, 5, 3, 8, 4, 2, 10, and 4 cases respectively; the injected fat amount was 2-110 mL (mean, 47 mL).
ResultsThe swelling period was from 5 to 15 days after operation (mean, 7 days), and there were no complications of infection, cyst, introvascular thrombogenesis, and so on. They were followed up 1-7 months (mean, 3 months). The effect of face rejuvenation was satisfactory.
ConclusionCosmetic zonation of face is helpful for preoperative evaluation of autologous fat grafting, and the fat granules injection asistor is beneficial to reach better effect of face rejuvenation.
ObjectiveTo three-dimensionally calculate the craniofacial parameters of midface of patients with Treacher Collins syndrome (TCS) in China, in order to understand the changes in the spatial position relationship between the various anatomical structures of the midface.MethodsCT imaging data of TCS patients and age- and gender-matched normal populations between January 2013 and July 2020 was retrospectively analyzed. A total of 33 cases met the selection criteria for inclusion in the study, including 14 cases in the TCS group and 19 cases in the control group. ProPlan CMF 3.0 software was used to perform three-dimensional digital reconstruction of the craniofacial bone, measure the anatomical parameters of the midface, and analyze its morphological structure; at the same time perform three-dimensional digital reconstruction of the upper airway for morphological analysis (measure upper airway volume).ResultsCT images analysis revealed that all 14 patients with TCS presented the typical features with downward slanting of the palpebral fissures and different degrees of zygomatico-orbital complex dysplasia. Cephalometric and morphological analysis of the midface revealed that, multiple transverse diameters of the midface of TCS patients were significantly decreased when compared with the control group (P<0.05), such as the width of the maxillary base, the length of the maxillary complex, and some distances related to the nasal morphology; but the distance between bilateral orbitales increased in TCS group (P<0.05). Several anteroposterior distances in TCS group were decreased significantly when compared to control group and the distance between the skull base point and the posterior nasal spine was the most shortened (P<0.05). But there was no significant difference of the distance between nasion and anterior nasal spine, which represented anterior midface height, between groups (P>0.05). The skull base angle and SNB angle (the angle between the sella point-nose root point-inferior alveolar seat point) of the TCS group both decreased when compared with the control group (P<0.05), but there was no significant difference in SNA angle (the angle between the sella point-nose root point-upper alveolar seat point) between the two groups (P>0.05). The total volume of the upper airway was (24 621.07±8 476.63) mm3 in the TCS group, which was significantly lower than that of the control group [(32 864.21±13 148.74) mm3] (t=2.185, P=0.037).ConclusionThe transverse distances, anteroposterior distances, and multiple craniofacial angles measurement of TCS patients were significantly decreased when compared to the control group, presented with different degrees of zygomatico-orbital complex dysplasia, nasal and maxillary dysplasia, but there was no obvious restriction in face height development. Reduced internal diameters of the upper airway maybe responsible for the decreased upper airway volume of patients with TCS.

Methods The clinical data of five elder patients with cutaneous angiosarcoma on the scalp and face from 1996 to 2008 were retrospectively analyzed. The patients underwent the light microscopy, pathomorphological examination, and immunohistochemistry. Four patients were followed up. Results Most clinical manifestation was dusky irregular erythematous plaques which were often ulcerated. The tumor was composed of asymmetric collection of angulated and irregular vascular spaces infiltrating between collagen bundles. Endothelial cells attaching to the vascular spaces had hyperchromatic irregular nuclei and prominent nucleoli. Hemorrhage was another histologic feature. Positive expression of CD34,CD31,Fli-1 and FⅧ were found in tumor cells, and expression of CD117 and CK8/18 was found in some of the patients. In the follow-up duration, three patients died in three years, and one failed to be followed up. Conclusion Cutaneous angiosarcoma of the scalp and face has various histomorphology and poor prognosis, which should be diagnosed and treated in time. It should be distinguished from benign cutaneous hemangioma, poorly differentiated carcinoma, malignant melanoma and malignant spindle cell tumor.
Objective To investigate the characteristics of the clinical application of ulnar artery flap in the repair of oral and maxillofacial soft tissue defects. Methods The clinical data of 12 patients with oral and maxillofacial defects repaired with ulnar artery flap between June 2021 and July 2023 was retrospectively analyzed. Among them, 11 cases were male and 1 case was female; their ages ranged from 28 to 76 years, with a mean age of 54.8 years. The lesions were located in the lateral margin of the tongue in 3 cases, the root of the tongue in 2 cases, the base of the tongue in 4 cases, and the buccal region, upper gingiva, and lower lip in 1 case each. The pathological types were squamous cell carcinoma in 11 cases and adenoid cystic carcinoma in 1 case; according to the TNM staging of the International Union Against Cancer (UICC), there were 5 cases of T3N0M0, 2 cases of T3N1M0, 1 case of T4aN0M0, 1 case of T4aN1M0, 1 case of T4aN2bM0, and 2 cases of T4aN2cM0. After complete resection of the lesion, the defect ranged from 6 cm×3 cm to 8 cm×5 cm. Preoperatively, colour Doppler ultrasound was used to detect the non-dominant forearm, measure the thickness of the subcutaneous fat in the donor area, confirm and mark the ulnar artery and reflux vein, and measure the diameter of the vessels, flow velocity, and the perforator position; intraoperatively, the flap was designed, prepared, anastomosed, and positioned according to the corresponding data. The vessels were all anastommosed with one artery and two veins to form a super-reflux. After complete hemostasis, the defects were repaired with sliding flap (2 cases), direct suture (4 cases), biomembrane (2 cases), or razor thin skin graft (4 cases). Results No vascular crisis occurred after operation, and all the flaps survived in 12 cases. Wounds in the donor site healed by first intention in 10 cases and by second intention in 2 cases. Wounds in the recipient site healed by first intention in all cases. All 12 patients were followed up 5-18 months, with an average of 11.4 months. The colour and texture of the flap were normal. The function of hand and upper limb was evaluated according to the trial standard of upper limb function assessment of the Chinese Society of Hand Surgery of the Chinese Medical Association, and the score was 65-81 (mean, 71.3), and achieved excellent in 1 case and good in 11 cases. The score of Oral Health Impact Scale (OHIP) was 9-18, with an average of 14.2, and the oral function was satisfactory. During the follow-up, 1 case had local recurrence and underwent extended resection again, while the other patients had no recurrence or metastasis. Conclusion For moderate soft tissue defects with complex oral and maxillofacial function, ulnar artery flap repair is effective.
OBJECTIVE To evaluate the effect of tissue flap pedicled with the superficial temporal artery in repairing deformity of the head and face in children. METHODS From October 1986 to December 1996, 13 children with deformity of the head and face were repaired by this tissue flap.

Among the flaps, 1 was temporal skin flap, 3 were temporal flap with hairbearing scalp, 1 was frontal skin flap, and 8 were posterio-uricular superficial fascia flap and skin flap. The area of tissue flap was ranged from 5.0 cm x 1.2 cm to 10.0 cm x 5.0 cm. The length of the pedicle was 5-8 cm. RESULTS All tissue flaps healed with first intention. Followed up for 6 months to 12 years, the appearance and function of tissue flaps were satisfactory. CONCLUSION The tissue flap pedicled with the superficial temporal artery is suitable to repair many kinds of deformities of the head and face in children. It has the advantages of good blood supply, closely acceptor area, easy operation and satisfactory appearance.
Objective
To review the research progress of midfacial fat compartments, and to thoroughly understand its current state of the anatomy and the aging morphologic characters of midfacial fat compartments, as well as the current status of clinical applications.
Methods
The recent literature concerning the midfacial fat compartments and related clinical applications were extensively reviewed and analyzed.
Results
Midfacial fat layer has been considered as a fusion and a continuous layer, experiencing a global atrophy when aging. As more anatomical researches have done, recent studies have shown that midfacial fat layer is broadly divided into superficial and deep layers, which are both divided into different fat compartments by fascia, ligaments, or muscles. Midfacial fat compartments tend to atrophy with age, specifically in the deep fat compartments while hypertrophy in the superficial fat compartments. Clinical applications show that fat volumetric restoration with deep medial cheek fat and Ristow’s space can restore the appearance of midface effectively.
Conclusion
In recent years, the researches of midfacial fat compartments have achieved obvious progress, which will provide new ideas and basis for fat volumetric restoration. Corresponding treatments are selected based on different sites and different layers with different aging changes, reshaping a more youthful midface.
