“…For patients with prominent mandibular angle and broad chin deformity, we adopted a single-stage en-bloc MABCCO technique instead of the standard MAO. [ 22 ] The operation of MABCCO procedure is more complicated than MAO, and has a higher risk of intraoperative bleeding due to increased osteotomy area. Concerning MABCCO procedure, no correlations was found between volume of i-BD and any of the 3 indicators of postoperative bleeding variables (24-DV, t-DV, and DT) in the study group ( P > .05).…”

“…Introduction of specific operation can be referred to in our previous work. [21][22][23][24] As one of the most important step of the surgery, the surgical area was thoroughly rinsed, and hemostatic gauze was placed on the MAO area after removal of bones. Details of this procedure are as follows: a piece of soluble hemostatic gauze (Fig.…”

Background: In facial contour surgery, due to the narrow field of vision in the oral approach and the abundant blood supply to the maxillofacial area, hemostasis is not easy. The purpose of this study was to evaluate the hemostatic effect of soluble hemostatic gauze. Methods: We organized a prospective randomized study of 282 patients receiving facial contouring surgery (4 types of procedures in total) during 2016.1.1 to 2018.12.30. For each type of procedure, patients were randomly divided into study group (received hemostatic gauze) and control group (received sterile gauze). Two groups were compared for each type of procedure regarding 5 major perioperative variables: intraoperative blood loss, operation time, 24-hour postoperative drainage volume, total postoperative drainage volume, and postoperative drainage time. Correlation between variables was analyzed. Results: Compared with control group, the study group had higher amount of intraoperative blood loss in mandibular angle ostectomy (MAO) ( P < .01) and mandibular angle-body-chin curved ostectomy procedures ( P < .05), less total postoperative drainage volume in MAO ( P < .01) but not in malarplasty with MAO and partial masseter muscle resection along with MAO procedures. No significant difference was observed between respective study and control groups regarding operation time, 24-hour postoperative drainage volume, and postoperative drainage time in any of the 4 types of surgery. In all 4 types of procedures, a strongly positive correlation was observed between total drainage volume and 24-hour drainage volume in both the study and control groups ( r : 0.88–0.97, P < .01). Conclusion: The effect of hydroxyethyl cellulose soluble hemostatic gauze on hemostasis in facial contouring surgery is associated with the type of surgery, which can reduce the risk of postoperative bleeding in MAO. However, for surgery with relatively large amount of intraoperative and postoperative bleeding, the hemostatic gauze had a limited postoperative hemostasis efficacy, which needs further evaluation.

“…Osteotomy is conducted before soft tissue correction to achieve facial bone symmetry. Based on the 3D images, mandibular outer cortex grinding, mandibular angles osteotomy and reduction malarplasty are conducted in the standard fashion 11,12 . Subapical osteotomy of mandibular anterior teeth and genioplasty is performed when necessary.…”

Background The refractory port‐wine stains are often associated with soft and hard tissue hypertrophy leading to facial asymmetry and psychological problems. Aims The authors describe and illustrate a surgical strategy for the treatment of both hard and soft tissue malformations in patients with port‐wine stains to restore facial symmetry. Methods The medical records, photographs of two patients with soft and hard tissue hypertrophy were reviewed. After physical examinations, 3‐dimensional computed tomography was conducted to evaluate bony asymmetry. The surgical strategy was designed according to individual malformation and requests. Results Both patients had congenital port‐wine stains that were resistant to laser therapy. As they grew up, they developed both soft and hard tissue hypertrophy. Zygoma, maxilla, nose, and lips are involved, causing facial asymmetry, deviated nose, increased dental show and malocclusion. To correct bony malformation, orthognathic surgery, and facial bone contouring including zygomatic reduction, mandibular angles osteotomy and genioplasty were performed. After the correction of the bony factor, soft tissue symmetry was improved via resection, autologous fat grafting, liposuction, and rhinoplasty. Both patients were satisfied with the surgical result. Conclusions To acquire facial symmetry, surgical correction is inevitable for patients with port‐wine stains associated with soft and hard tissue hypertrophy. The authors describe the successive correction of bony and soft tissue asymmetry to achieve harmonious surgical outcomes.
