Aim Image-guided sclerotherapy is becoming the preferred treatment for low-flow vascular malformations in head and neck region. The authors review the management protocol for this condition and evaluate its clinical outcomes. Methods Children with low-flow vascular malformations in head and neck region undergoing sclerotherapy from 2010 to 2013 were reviewed. All patients were assessed by pediatric surgeons and interventional radiologists in the multidisciplinary vascular anomalies clinic. Ultrasonography and intravenous contrast enhanced magnetic resonance imaging were performed preoperatively. Under general anesthesia with endotracheal intubation, sclerotherapy were performed with ultrasonographic and fluoroscopic guidance. Sodium tetradecryl sulfate (STS) foam or ethanolamine was used for venous malformation and doxycycline for lymphatic malformations as primary sclerosants, whereas 98% ethanol was reserved as an adjuvant sclerosant in selected cases of repeated procedures. Perioperative dexamethasone 0.2 mg/kg thrice daily was administered to decrease postsclerotherapy swelling and single dose intravenous mannitol 0.5 g/kg was given to minimize thromboembolic complications. Postoperatively, patients were admitted to intensive care unit for mechanical ventilation under deep sedation for airway protection. Results Overall 13 children (8 male and 5 female) with a mean age of 25 months (range, 2 mo-11 y) underwent a total of 25 sessions of image-guided staged sclerotherapy. There were five venous and eight lymphatic malformations. Location wise there were eight cervical, one lingual, one parotid, one lip, one facial, and one palatal lesions. Six patients had obstructive airway symptoms. Five patients required staged sclerotherapies from two to six sessions. There were no airway and thromboembolic complications. One patient had bleeding while another had recurrent swelling following sclerotherapy for lymphatic malformations and they were treated by aspiration. Significant size reductions of more than 50% volume were achieved in all patients. All patients with obstructive symptoms showed improvement. Conclusion Sclerotherapy is a safe and effective treatment for head and neck vascular malformations in children. Routine perioperative protocol is essential to reduce airway

PurposeLaparoendoscopic single-site surgery has recently been described in children and regarded as an improved technology leading to less pain and better cosmetic outcome. Compared to the traditional three-port method, it is not known if the single-port method is less invasive. The aim of this study was thus to investigate the post-operative acute inflammatory response in order to evaluate surgical stress in the two surgical approaches in children.MethodsA prospective, single blinded, case-control study was carried out. Thirteen male patients who presented with unilateral varicocele were divided into two groups. Six children underwent single-port laparoscopic procedure, while the other seven children underwent three-port laparoscopic procedure. Pre-operative and post-operative blood samples were taken for the measurement of tumor necrosis factor-α (TNF-α) and interleukin 6 (IL-6) using ELISA. Demographics including the operation time, and complications were recorded. Data between the two groups were analyzed using unpaired t-test and a p value of <0.05 was taken as statistically significant.ResultsThe mean age of patients was 14.5 years (range 12–19 years). There was no significant difference between the two groups in terms of operative time, nor there was any complication recorded. The change in serum TNF-α and IL-6 concentrations pre- and post-operatively between the single-port group and three-port group was not statistically significant. Overall, patients in the two groups showed excellent satisfaction in terms of post-operative cosmesis.ConclusionSingle-port laparoscopic varicocelectomy is safe, effective and produces excellent cosmesis with minimal surgical stress.

With significant relapse of nasal deformity at 9 months after the primary rhinoplasty despite the use of presurgical naso-alveolar molding and postoperative nasal stenting, overcorrection of the nasal configuration at primary rhinoplasty should be considered for optimal long-term nasal symmetrical outcome.
