Reverse Neurocutaneous Flap Based on the Dorsal Branch of the Ulnar Artery for Palm Coverage in Children: Long-Term Results.

PURPOSE: Although the palm is spared mostly in severe burn injuries, it often is affected in children and requires radical excision of contracting scar tissue to allow normal hand development. Since alternatives are limited for palmar coverage, we primarily use a reverse-perfused, neurocutaneous dorsal ulnar artery flap. We report here our long-term follow-up results. METHODS: We reviewed the long-term results of 10 postburn palmar contracture release and flap coverage procedures in 10 children. The applied flap was based distally on the dorsal branch of the ulnar artery and harvested along the ulnar aspect of the hand and wrist. The pivot point of the flap was located dorsally, close to the 4th and 5th metacarpal base. Patients were followed for a median period of 6 years (range, 4-20 years). RESULTS: Flap size ranged from 60-130 mm in length and 20-35 mm in width. This variation in flap dimensions resulted from different hand sizes, because of the various patient ages at surgery. All flaps survived, donor site healing was uneventful, and marginal flap necrosis occurred only once. Satisfactory restoration of range of motion without secondary contractures was observed. Moreover, we detected adequate progressive growth, adaptability and sensory recovery in all flaps. Over time, the flaps mostly become hairless and progressively flattened without debulking. CONCLUSIONS: The importance of this flap lies in the potential for considerable tissue mobilization to cover palmar defects without sacrificing any major vascular axis. The adequate progressive growth of the flap facilitates functional hand development in children. The predictable vascular anatomy, wide range, and durable, thin, and pliable skin make the reverse neurocutaneous dorsal ulnar artery flap an appealing option for soft tissue reconstruction of the palm in children. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic V.

Correction of Temporal Hollowing After Pterional Craniotomy by Autologous Fat Grafting. A Single-Center Experience.

OBJECTIVE: Aesthetic complications following neurosurgical procedures impact patient quality of life and self-perception. Postoperative temporal hollowing frequently is seen after temporal craniotomy, resulting mainly from atrophy of the temporal muscle. Autologous fat grafting is a tailorable method to correct such approach-related sequelae. We herein present our clinical patient series and discuss pearls and pitfalls of this method. METHODS: In this retrospective single-center study, correction of postoperative temporal hollowing using autologous fat grafting was performed in 16 patients. Temporal tissue thickness ratio was measured using magnetic resonance tomography images to visualize the graft. Patients, plastic surgeons, and neurosurgeons evaluated the results independently using the herein presented scale. RESULTS: The mean interval between the neurosurgical procedure and fat grafting was 62 months. A mean volume of 11.5 mL of autologous fat was injected in an average of 2.5 sessions after initial rigottomy. Temporal tissue thickness was significantly augmented at a mean of 2.2 years after the operation (mean 0.71 ± 0.25, range 0.43-1.1; P = 0.0214) as compared with the preoperative finding (mean 0.48 ± 0.1, range 0.32-0.6). Patients were more satisfied with the results than were surgeons, reflecting the significant impact of the deformity on patient self-esteem. CONCLUSIONS: Autologous fat grafting is a valuable method for correcting postoperative temporal hollowing that provides stable results, high patient and surgeon satisfaction, and can be tailored to the patient's individual needs. It should not be considered a merely aesthetic operation but an important rehabilitation step towards restoring the patient's quality of life.

Chronic caesarian section scar pain treated with fascial scar release techniques: A case series.

OBJECTIVE: To describe outcomes of two subjects with chronically painful Caesarian section (C-section) scars following an intervention of specific myofascial scar release techniques. STUDY DESIGN: Case series. BACKGROUND: Over 1.3 million C-sections are performed annually in the US. Anywhere from 7 to 18% of those will develop chronic scar pain. Although anecdotal evidence supporting the use of fascial release in reducing surgical scar pain exists, almost no research has been published. METHODS AND MEASURES: Two subjects who both underwent two C-sections resulting in chronic discomfort of 6-9 years duration participated in this study. Both reported premenstrual pain, pain upon pressure to the lower abdomen, and pain during bowel movements. Subject 1 also reported sharp pain with bed mobility. Four, 30-min treatment sessions over a period of two weeks consisted of stretching the scar until a release in tissue tension was felt by the treating therapist. Outcome measures included pain and pressure tolerance using a Pressure Algometer, measurements of scar flexibility using an Adheremeter, and the Numeric Pain Rating Scale (NPRS). These measures were collected at baseline, five days after the final treatment and at four weeks. RESULTS: Both subjects demonstrated improvements in all outcome measures. At four weeks, pressure tolerance at all point improved as much as 79% (p < 0.0001) and scar mobility increased in all directions at all points as much as 200% (p < 0.0001). Following treatment, both subjects rated their premenstrual pain for all previously painful activities at 0/10 for the first time since their surgeries. CONCLUSIONS: These results suggest that scar release techniques may help reduce chronic scar pain in women who have had C-section surgery.

Novel use of a flowable collagen-glycosaminoglycan matrix (Integra™ Flowable Wound Matrix) combined with percutaneous cannula scar tissue release in treatment of post-burn malfunction of the hand--A preliminary 6 month follow-up.

INTRODUCTION: Long-term function following severe burns to the hand may be poor secondary to scar adhesions to the underlying tendons, webspaces, and joints. In this pilot study, we report the feasibility of applying a pasty dermal matrix combined with percutaneous cannula teno- and adhesiolysis. PATIENTS AND METHODS: In this 6 month follow-up pilot study, we included eight hands in five patients with hand burns undergoing minimal-invasive, percutaneous cannula adhesiolysis and injection of INTEGRA™ Flowable Wound Matrix for a pilot study of this new concept. The flowable collagen-glycosaminoglycan wound matrix (FCGWM) was applied with a buttoned 2mm cannula to induce formation of a neo-gliding plane. Post treatment follow-up was performed to assess active range of motion (AROM), grip strength, Disabilities of the Arm, Shoulder and Hand (DASH) score, Vancouver Scar Scale (VSS) and quality of life Short-Form (SF)-36 questionnaire. RESULTS: No complications were detected associated with the treatment of FCGWM injection. The mean improvement (AROM) at 6 months was 30.6° for digits 2-5. The improvement in the DASH score was a mean of 9 points out of 100. The VSS improved by a mean of 2 points out of 14. DISCUSSION: The study demonstrates the feasibility and safety of percutaneous FCGWM for dermal augmentation after burn. Results from this pilot study show improvements in AROM for digits 2-5, functional scores from the patient's perspective (DASH) and scar quality (VSS). The flowable form of established INTEGRA™ wound matrix offers the advantage of minimal-invasive injection after scar release in the post-burned hand with a reduction in the risk of postsurgical re-scarring.
