RESUMO

SUMMARY: Alar contour grafts are an excellent adjunct in both primary and revision rhinoplasty for correction and prevention of alar rim irregularities. They are traditionally placed at the conclusion of a rhinoplasty through a vestibular incision along the underside of the alar rim. Alternatively, alar base resection provides an opportunity for precise retrograde placement of alar contour grafts. The purpose of this article is to describe an efficient, five-step technique for retrograde placement of alar contour grafts in the setting of concomitant alar base surgery.

RESUMO

BACKGROUND: Small joint reconstruction of the hand poses a significant challenge, especially in children where both functional motion and preservation of the epiphysis are desired. Auto-transplantation of whole joints is the only way to reconstruct a functional joint that maintains growth potential. Historically, nonvascularized toe-to-finger joint transfer has been criticized for high rates of avascular necrosis and joint dissolution, while vascularized transfers seemingly resulted in increased durability of the joint space and epiphysis. However, certain populations remain poor candidates for microvascular reconstruction, such as those with congenital deformities or sequelae from trauma or infection. In our case series, we demonstrate that a simplified nonvascularized surgical technique and careful patient selection can produce stable, functional joints. METHODS: Nonvascularized toe-to-finger joint transfer was performed in 3 children between the ages of 4 and 6. Reconstructed joints included 2 proximal interphalangeal (PIP) joints and 1 metacarpophalangeal (MCP) joint. Donor grafts consisted of second toe PIP joints harvested en bloc to include the epiphysis of the middle phalanx, collateral ligaments, volar plate, and a diamond-shaped island of extensor tendon with its central slip attachment. RESULTS: Follow-up ranged from 7 to 29 months. Each patient demonstrated functional improvements in joint motion and stability. Postoperative radiographs confirmed adequate joint alignment and persistence of the joint spaces. Epiphyseal closure was observed in 1 patient as early as 25 months postoperatively. CONCLUSIONS: Nonvascularized joint transfer should remain a practical consideration for small joint reconstruction of the hand in certain pediatric patients.

RESUMO

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Comprehend anatomy and biomechanics of the normal and arthritic trapeziometacarpal joint. 2. Evaluate best evidence for diagnosis and for operative and nonoperative treatment of thumb osteoarthritis. 3. Understand treatment pitfalls of basilar joint arthritis and complication avoidance. SUMMARY: Articular and ligamentous anatomy of the trapeziometacarpal joint enables complex motions. Disability from arthritis, common at the trapeziometacarpal joint, is debilitating. Furthering the understanding of how trapeziometacarpal arthritis develops can improve treatment. The authors provide current best evidence for diagnosis and treatment of basilar joint arthritis. Pitfalls in treatment are discussed.

RESUMO

Total ear reconstruction has been approached by several techniques involving autologous graft, prosthetic implant, and alloplastic implant options. Recent studies have shown the superiority of porous polyethylene (Medpor, Porex Surgical) reconstruction over autologous reconstruction based on improved aesthetic results, earlier age of intervention, shorter surgery times, fewer number of required procedures, and a simpler postoperative recovery process. A durable and permanent option for total ear reconstruction, like Medpor, can help alleviate the cosmetic concerns that patients with auricular deformities may be burdened with on a daily basis. In this article, the authors discuss the advantages of Medpor-based ear reconstruction and discuss recent advances in the surgical techniques involved, such as harvesting a temporoparietal fascia flap and full-thickness skin graft to adequately cover the Medpor framework and decrease extrusion rates.

RESUMO

Syndactyly is one of the most common congenital hand anomalies treated by pediatric plastic surgeons. Established principles of syndactyly separation dictate the timing and order of syndactyly release, with the goals of surgery being the creation of an anatomically normal webspace, tension-free closure of soft tissue, and return of function to the fingers. Numerous surgical methods have been described, many of which involve the use of local flaps to reconstruct the commissure and full-thickness skin grafts for coverage of raw areas. Recently, reconstructive techniques without the use of skin grafts have been devised, which work well for certain indications. Special considerations are described for complete, complex, and syndromic syndactylies. Outcomes for simple syndactyly release are typically good when surgical principles are followed, whereas complex syndactyly release tends to have less-favorable outcomes and more complications.

RESUMO

Preaxial polydactyly is a common, often sporadic, congenital anomaly that must be addressed surgically early in life. Ideally, the surgeon seeks to accomplish three goals: construction of a thumb that is adequate in size, preservation of pinch function, and reconstruction of all components in one procedure. Although each case is unique, several classification systems attempt to describe the various types. In this article, the authors discuss the various classification systems, procedures, and outcomes after surgery for pediatric thumb duplication.

RESUMO

BACKGROUND: Conjoined twins are a rare medical phenomenon that offers a unique challenge for medical professionals. The complex anatomy of conjoined twins dictates their survival and amenability to separation, making each case different in terms of medical management, surgical planning, and patient outcomes. Thoraco-omphalo-ischiopagus twins, joined from the thorax to the pelvis, are one of the rarest orientations recorded in the medical literature, and successful separation of this subset of conjoined twins has not been documented. This report presents a novel case of thoraco-omphalo-ischiopagus tetrapus twins who were successfully separated at 10 months of age. The preoperative planning, operative details, and postoperative course are discussed as they relate to the reconstructive effort. METHODS: Three-dimensional medical modeling was pursued early in the planning process and was used to estimate the soft-tissue requirements for reconstruction and to design custom tissue expanders. RESULTS: The reconstructive effort required postponement until respiratory status was optimized. Even with elaborate preoperative planning, primary closure of the abdomen was limited because of tissue edema and other less predictable patient factors. Delayed closure of the abdominal wall was made possible with negative-pressure wound therapy and secondary flap advancements. CONCLUSION: Preoperative coordination with necessary vendors, a multidisciplinary surgical effort, and optimal timing of the surgical intervention all contribute to the successful separation and long-term survival of thoraco-omphalo-ischiopagus conjoined twins. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

RESUMO

BACKGROUND: Long-term success in pediatric lung transplantation is limited by infection and bronchiolitis obliterans syndrome (BOS). The bilateral sequential lung transplantation (BSLT) technique may result in airway ischemia leading to bronchial stenosis, dehiscence, or loss of small airways. En bloc lung transplant (EBLT) with bronchial artery revascularization (BAR) minimizes airway ischemia, thus promoting superior airway healing. BAR also allows for safe tracheal anastomosis, circumventing the need for bilateral bronchial anastomoses in small children. METHODS: This was a retrospective review of bilateral transplantations from 2005 to 2014. Both techniques were used in parallel. Redo and multiorgan transplants were excluded. RESULTS: There were 119 recipients comprising 88 BSLTs and 31 EBLTs. Follow-up time was 3 years (interquartile range, 1-5 years). Donor ischemic and cardiopulmonary bypass times were not different between techniques (p = 0.48 and p = 0.18, respectively). Degree of graft dysfunction and cellular rejection scores were not different (p = 0.83 and p = 0.93, respectively). There were 3 hospital deaths after BSLT and 2 after EBLT (p = 0.60). Overall survival was 61% for the BSLT group and 77% for the EBLT group (p = 0.54). Freedom from BOS was 71% in the BSLT group and 94% in the EBLT group (p = 0.08). On routine bronchoscopy, 57% BSLT and 16% EBLT patients had 1 or more airway ischemic findings (p < 0.0001). Multivariate analysis showed BSLT was associated with higher ischemic injury (relative risk, 2.86; 95 confidence interval, 1.3-6.5; p = 0.01) and non-airway complications (relative risk, 4.62; 95% confidence interval, 1.1-20.2; p = 0.04) but not airway reinterventions (p = 0.07). Airway dehiscence occurred in 3 BSLT patients. CONCLUSIONS: Pediatric EBLT with BAR can be safely performed without increasing operative or graft ischemic times. Airway ischemia and non-airway complications were significantly reduced when BAR was combined with tracheal anastomosis, potentially diminishing morbidity caused by anastomotic healing complications.

RESUMO

BACKGROUND: Although surgical results for repair of coarctation of the aorta (CoA) have steadily improved, management of this condition remains controversial. The purposes of this study were to analyze the long-term outcomes of patients undergoing CoA repair through left thoracotomy and to define risk factors for reintervention. METHODS: All patients who were less than 18 years old and who underwent initial repair of CoA through left thoracotomy from 1995 to 2013 at Texas Children's Hospital (Houston, TX) were included. Patients were classified into 3 groups: 143 (42%) neonates (0 to 30 days old), 122 (36%) infants (31 days to 1 year old), and 78 (23%) older children (1 to 18 years old). Univariate and multivariate analyses were performed. RESULTS: A total of 343 patients (129 [38%] girls) with median age of 53 days (interquartile range [IQR],12 days to 9 months) and weight of 4.1 kg (IQR, 3.1 to 8.0) underwent repair with extended end-to-end anastomosis (291 patients [85%]), end-to-end anastomosis (44 patients [13%]), interposition graft (2 patients [0.6%]), or subclavian flap (6 patients [2%]). Concomitant diagnoses included genetic abnormalities (48 patients [14%]), isolated ventricular septal defects (58 patients [17%]), small left-sided structures (53 patients,16%), or other complex congenital heart disease (18 patients [5%]). Perioperative mortality was 1% (n = 4, all neonates). At a median follow-up of 6 years (7 days to 19 years), only 14 (4%) patients required reintervention (10 catheter-based procedures, 6 surgical repairs). A postoperative peak velocity of 2.5 m/s or greater was an independent risk factor for reintervention (odds ratio [OR], 4.0; 95% confidence interval [CI], 1.4 to 11.6). Within the cohort, 95 (33%) patients were hypertensive or remained on cardiac medications a median of 12 years (6 months to 19 years) after the surgical procedure. Development of perioperative hypertension was associated with higher risk of chronic hypertension or cardiac medication dependency (OR, 1.9; 95% CI, 1.1 to 3.3). CONCLUSIONS: CoA repair through left thoracotomy is associated with low rates of morbidity, mortality, and reintervention. Aortic arch obstruction should be completely relieved at the time of surgical intervention to minimize the risk of long-term recoarctation.
