ABSTRACT
Objective:To evaluate the clinical effect of remodeling the dense dermal fiber structure in the suprapical region on the correction of nasal hypertrophy.Methods:A retrospective analysis was carried out in beauty-seeking patients who underwent comprehensive costal cartilage rhinoplasty with nasal hypertrophy in our hospital from September 2016 to February 2018. The technique of horizontal scratch reconstruction and deep dermal suture fixation at the tip of the nose was used to fix the dense fibrous dermal fiber structure in the suprapical area. Photos were followed up 12 months after the operation to observe whether the suprapical area had arch and upward displacement of the nasal tip.Results:All patients healed primarily, and the patients were satisfied with the effects. Follow-up results showed that only one female patient showed upshift of nasal tip after surgery among the 57 patients with hypertrophy of nasal tip for beauty. The remaining 56 patients had no upward movement of the nose tip and arching of the upper turning area.Conclusions:By reshaping the dense dermal fiber structure of the suprapical area, the suprapical area of the patients who seek beauty after the operation will have a natural transition, beautiful shape and stable nasal structure.
ABSTRACT
Objective:To evaluate the advantages of cortical perichondrium retention of costal cartilage in tip plasty.Methods:A total of 618 female cases were retrospectively analyzed from July 2017 to July 2018 in Zhengzhou Meilai Medical Beauty Hospital that underwent comprehensive line of rib cartilage rhinoplasty for beauty, aged 18-52 years with mean 27±6 years. According to different modification graft used in plasty, the cases were divided into reserve costal perichondrium cortex group (experimental group) and simple rib cartilage cortex group (control group). Statistical analyses were carried out 1 month and 12 months after operation. The tip displacement visualization was compared between the two groups and the advantages and disadvantages were evaluated in both.Results:After the surgery of the 618 patients, the rate of displacement in the experimental group was 3.6%, and that in the control group was 7.9% (χ 2=4.95, P<0.05). The rate of the implant exposure in the experimental group was 4.7%, and that in the control group was 9.1% (χ 2=4.38, P<0.05). The reserve costal perichondrium cortex used in the nasoplasty kept the prominent and stable nasal tip after the operation, and longterm follow-up showed there were no displacement and deformation occured in the patients. Conclusions:The application of costal cartilaginous cortex retaining costal perichondrium in tip plasty can obtain good nasal tip protrusion and stable rotation. It is an ideal nasal tip shaping material and worthy of clinical application.
ABSTRACT
Objective To investigate the value of D-dimer in predicting the progression of lower extremity deep venous thrombosis (DVT) during perioperative period of gastrointestinal surgery.Methods Color Doppler ultrasound was used to dynamically monitor the formation and changes of perioperative deep venous thrombosis (DVT) in 239 patients receiving abdominal surgery in our department from Nov 2014 to Aug 2016.Changes of plasma D-dimer were measured,and clinical data of malignant tumor,infection,age,BMI were collected.The relationship between D-dimer elevation and DVT progression was analyzed.Results Lower extremity DVT after surgery developed in 97 patients,and thrombosis progression occurred in 16.6％ (16/97).Univariate logistic regression analysis showed that continuous increase of postoperative D-dimer was closely related to the progression of thrombosiss.Multivariate Logistic regression analysis showed that the continuous rise of D-dimer was an independent risk factor for thrombosis.ROC curve analysis showed significantly increased risk of thrombosis progression,when plasma D-dimer polymerization increased ＞0.87 mg/L on the 3rd day.Conclusion The continuous increase of D-dimer ＞ 0.87 mg/L predicts DVT progression of lower extremity DVT.
