Scientific validation of clinical visual scales and Antera 3D™ consistency with derived measurements in the assessment of infantile haemangioma after laser therapy.

BACKGROUND: Laser therapy is a treatment for infantile haemangiomas. The efficacy of laser therapy for red lesions is determined by visual evaluation; however, this assessment is inaccurate and lacks objectivity. OBJECTIVE: To scientifically validate the consistency between pre- and post-treatment visual assessment grades for infantile haemangioma treated with pulsed dye laser (PDL) and the values calculated from images obtained with Antera 3D™. METHODS: This study involved 81 cases of infantile haemangiomas treated with PDL alone from 2012 to 2015 and with Antera 3D™ images of the lesions. Using images obtained before treatment and 4-6 weeks after the last treatment, the lesions were rated using a visual four-step scale. Ratings were categorised as Poor/Fair/Good/Excellent by the degree of improvement in the red colour tone. The red colour ratio was calculated using the haemoglobin distribution in the lesion and surrounding skin, and the improvement difference and improvement rate were then obtained. The correlation between the improvement difference and improvement rate, and visual evaluation was statistically analysed. RESULTS: No serious adverse effects were observed, with an average of 4.3 treatments per patient; 60.1% of the patients achieved Good/Excellent results. There were statistically significant differences in the post-treatment red colour ratio and improvement ratio in each category after visual evaluation classification. The improvement rate and the four visual grades were statistically correlated. CONCLUSION: This study confirmed the scientific validity of visual evaluation and the evaluation criteria calculated from Antera 3D™. This method could objectively determine treatment effectiveness.

Maxillary reconstruction using chimeric flaps of the subscapular artery system without vein grafts and the novel usage of chimeric flaps.

The purpose of this study was to overcome the disadvantages associated with the shortness of the vascular pedicle of subscapular system combined flaps when performing the maxillary reconstruction procedure. Combined flaps of the subscapular artery system were used for maxillary reconstruction. A latissimus dorsi myocutaneous flap, a scapular fasciocutaneous flap, and two kinds of scapular bone flaps were elevated as combined flaps. Next, the circumflex scapular artery (CS) and vein were cut off from the combined flaps and anastomosed to the serratus anterior branch, thereby establishing chimeric flaps. Then, maxillary reconstruction was performed using these flaps. We encountered two patients who underwent maxillectomy for maxillary cancer. Satisfactory improvements in facial shape were obtained in both cases. In cases in which combined flaps of the subscapular artery system are used for maxillary reconstruction, the biggest problem is that the vascular pedicle does not reach the recipient vessel in the neck due to the shortness of the CS. Therefore, vein grafts are generally performed to extend the flaps to the maxilla. Our novel procedure has the great advantages of long vascular pedicles and high flexibility in setting the flaps without the use of vein grafts.

Objective assessment of the efficacy of supermicrosurgical lymphaticovenous anastomosis and microsurgical lymphaticovenous implantation in a case of axillary lymphorrhea.

Supermicrosurgical lymphaticovenous anastomosis and microsurgical lymphaticovenous implantation are procedures currently used to treat lymphedema. However, because in most cases concomitant conservative treatments are included, it is difficult to objectively assess the direct effect of the procedures. The present report is a case in which supermicrosurgical lymphaticovenous anastomosis and microsurgical lymphaticovenous implantation were performed to treat axillary lymphorrhea that developed after the treatments for lymph node metastases of esophageal carcinoma. Prior to surgery, the volume of lymphorrhea was approximately 300 mL/d, but from postoperative day 1, this amount decreased by half, and healing was obtained by postoperative day 20. This result objectively indicates that creating new lymphatic routes with these two procedures is clearly effective.
