Use of Acellular Dermal Matrix in Treatment of Congenital Muscular Torticollis in Patients Over Eight Years of Age.

BACKGROUND: Treatment for neglected or recurred congenital muscular torticollis should be differentiated from primary patients due to the long-standing adjacent tissue contracture. The aim of this study was to evaluate the effect of acellular dermal matrix (ADM) on surgery of recurred and neglected patients of congenital muscular torticollis. METHODS: Forty-nine patients were included in the study. All patients underwent resection at the distal end of the sternocleidomastoid muscle. In the study group of 18 patients (ADM group), the defect caused by myectomy and scar tissue removal was covered with ADM. Passive range of neck motion, head tilt, cosmetic and functional satisfaction, and scar was evaluated and compared with the control group of 31 patients (non-ADM group) during follow-up. Logistic and linear regression analyses with adjustment by propensity score were performed to determine the association between ADM implantation and postoperative variables. RESULTS: The mean follow-up period was 18.8 months. No patient required further operation for recurrence during follow-up. The improvement of neck motion in ADM group was significantly superior to non-ADM group at the 1-year follow-up, and the overall assessment score was significantly higher in the ADM group. Acellular dermal matrix implantation was not associated with increased discharge of total drain. CONCLUSIONS: In patients over 8 years of age with recurred or neglected congenital muscular torticollis, use of dermal substitute to fill the defect caused by torticollis release is effective in achieving satisfactory neck motion. Surgical sectioning of the sternocleidomastoid muscle and ADM graft should be considered in recurred and neglected torticollis.

Computed tomography contrast media extravasation: treatment algorithm and immediate treatment by squeezing with multiple slit incisions.

In our hospital, an adverse event reporting system was initiated that alerts the plastic surgery department immediately after suspecting contrast media extravasation injury. This system is particularly important for a large volume of extravasation during power injector use. Between March 2011 and May 2015, a retrospective chart review was performed on all patients experiencing contrast media extravasation while being treated at our hospital. Immediate treatment by squeezing with multiple slit incisions was conducted for a portion of these patients. Eighty cases of extravasation were reported from approximately 218 000 computed tomography scans. The expected extravasation volume was larger than 50 ml, or severe pressure was felt on the affected limb in 23 patients. They were treated with multiple slit incisions followed by squeezing. Oedema of the affected limb disappeared after 1-2 hours after treatment, and the skin incisions healed within a week. We propose a set of guidelines for the initial management of contrast media extravasation injuries for a timely intervention. For large-volume extravasation cases, immediate management with multiple slit incisions is safe and effective in reducing the swelling quickly, preventing patient discomfort and decreasing skin and soft tissue problems.

Vascularized Free Lymph Node Flap Transfer in Advanced Lymphedema Patient after Axillary Lymph Node Dissection.

Lymphedema is a condition characterized by tissue swelling caused by localized fluid retention. Advanced lymphedema is characterized by irreversible skin fibrosis (stage IIIb) and nonpitting edema, with leather-like skin, skin crypts, and ulcers with or without involvement of the toes (stage IVa and IVb, respectively). Recently, surgical treatment of advanced lymphedema has been a challenging reconstructive modality. Microvascular techniques such as lymphaticovenous anastomosis and vascularized lymph node flap transfer are effective for early stage lymphedema. In this study, we performed a two-stage operation in an advanced lymphedema patient. First, a debulking procedure was performed using liposuction. A vascularized free lymph node flap transfer was then conducted 10 weeks after the first operation. In this case, good results were obtained, with reduced circumferences in various parts of the upper extremity noted immediately postoperation.
