0.05). Conclusions Ultrasonography is an objective, accurate, non-invasive and utility method to evaluate the saphenous artery of saphenous skin flap before operation.

ObjectiveTo evaluate the accuracy of the modalities in revealing the results by observing the radiofrequency ablated (RFA) lesions with contrast-enhanced ultrasonography (CEUS),magnetic resonance image (MRI) in comparison with histopathologic findings in normal rabbit kidney.Methods RFA was performed in the left kidneys of 10 rabbits.The ablated lesions were observed with conventional ultrasound(US),CEUS,MRI at 1 day,1 week after RFA.Then the rabbits subjected to postmortem and the kidney specimens were excised,stained and processed for conventional histologic study.The maximum lesion size as measured on US,CEUS and MRI was then correlated with the histopathologically determined lesion size.The utility of different imaging modalities were evaluated.ResultsIn a relatively short time (at 1 day and 1 week),CEUS and MRI may reveal the location,shape and extent of ablated lesion.And the lesion sizes with CEUS,MRI and kidney specimens were well correlated (P＞0.05).ConclusionsBoth CEUS and MRI are suitable for the accurate evaluation of the ablated lesions in the short time.CEUS can reveal the variation of flow perfusion in the ablated lesion dynamicly and in real time.

Objective To afford an new effective imaging technique for the morphological observation of the normal male pelvic floor by observing the normal male puborectalis with transrectal ultrasound and magnetic resonance imaging (MRI). Methods Thirty-six normal males were examined by transrectal ultrasound and MRI,data of puborectalis were recorded and compared including starting point, end point,appearance, structure, thickness and the relationship with peripheral organs. Results The results including the appearance,direction and internal echo of puborectalis and the relationship with peripheral organs can be clearly displayed by transrectal ultrasound compared with MRI. The thickness of right and left puborectalis at rest measured in ultrasound and in MRI were (6.22±0.57)mm, (6.19±0.59) mm, (6.20±0.61) mm and (6.17±0.53) mm, respectively. The thickness by two methods and two sides had no significant differences (P>0.05). The thickness of puborectalis measured by two methods did not correlate with age,height,body weight,the volume of prostate and interspinal diameter respectively. Conclusions Transrectal ultrasound is a new imaging method to observe male puborectalis. Identification for nomal puborectalis sonography is the foundation of diagnosis pelvic floor disease.

Objective:To explore the clinical effect of the V-Y plasty of musculocutaneous flap in repairing the excessive width of inner canthus deformity.Methods:Retrospective analysis was performed between July 2018 and June 2021 in patients treated with this method. V-Y design along the inner corner of the eye before operation. The key points of operation are the elevated under the orbicularis oculi muscle. The skin orbicularis oculi muscle flaps are formed on both sides of the incision. After the V-Y of the outside myocutaneous flap is advanced and formed at the new medial canthus point, the V-Y of the orbicularis oculi muscle and the skin are sutured in layers. The degree of reduction of the inner canthus width, epicanthal fold shape, incision scarring, and patient satisfaction was followed up. All patients were measured at the preoperative and postoperative review to record data of the intercanthal distance, and used paired t-test for statistical analysis. P<0.05 was statistically significant. Results:83 patients, including 81 female patients and 2 males, with an average age of 28 years (19 to 56 years) were followed up from 3 months to 2 years, with an average of 1 year. The overexposure of the tear caruncle was significantly reduced, the asymmetry of the bilateral inner corners has been improved, the shape of the epicanthal folds reverted to its natural appearance and the old scars became inconspicuous; patient satisfaction evaluation: very satisfied 34.94% (29/83), satisfied 54.22% (45/83), relatively dissatisfied 6.02% (5/83), dissatisfied 4.82% (4/83). Among the 4 cases of dissatisfaction, 2 cases were due to insufficient correction and were re-operated to obtain satisfactory result, 1 case was improved by reoperating due to excessive correction which led to the reduction of inner canthal distance, 1 case regrets surgery the next day after surgery and cannot accept the appearance and strongly requires removal and restoration. The distance between intercanthal distance of the patients was 28.8 mm to 38.0 mm, average (33.58±3.34) mm before the operation, and 32.2 mm to 41.5 mm, average (37.47±2.90) mm after the operation, an average increase of 3.89 mm ( t=-15.78, P<0.001) after the operation. Conclusions:The V-Y plasty of musculocutaneous flap is suitable for the repair of excessive width of inner canthus deformity after epicanthoplasty. The design idea is simple, the postoperative effect is reliable, and the postoperative satisfaction rate of patients is high.
