Ear Abnormalities.

Congenital ear abnormalities present an aesthetic and psychosocial concern for pediatric patients and their parents. Diagnosis of external ear deformities is based on clinical examination and is facilitated by an understanding of normal ear anatomy. Ear anomalies can be categorized as malformations or deformations. Malformations are characterized by absent anatomical structures of the ear (or absence of the ear itself), as exemplified by microtia and anotia. Ear deformations are characterized by ear anatomical landmarks that are present but are distorted or abnormal, with Stahl ear, constricted ear, and prominent ear being common presentations. Ear malformations will not improve with growth of the patient and uniformly require surgical intervention to recreate an anatomically typical ear. Although a small percentage of ear deformations can self-resolve, most patients with ear deformations will require nonsurgical or surgical reconstruction to achieve a normal or more aesthetic ear. In recent decades the use of nonsurgical ear splinting or molding has been recognized as a highly effective method in correcting a variety of congenital ear deformations when treatment is initiated in the first 8 weeks of life. The urgency in initiating nonsurgical treatment of ear deformations at an early age makes prompt recognition of these ear deformations essential because surgical correction remains the only viable reconstructive option in older infants and children.

Role of CTA in Women with Abdominal Scars Undergoing DIEP Breast Reconstruction: Review of 1,187 Flaps.

BACKGROUND: This study examines the effect of prior abdominal surgery on flap, donor-site, and overall complications in women undergoing deep inferior epigastric artery perforator (DIEP) flap breast reconstruction and assesses whether preoperative computed tomography angiography (CTA) affects outcomes. METHODS: All DIEP flaps performed at our institution between 2004 and 2015 were identified retrospectively. Patients were stratified based on a history of prior abdominal surgery and whether or not they underwent a preoperative CTA. A subgroup analysis was performed to compare operative times and incidence of complications using adjusted odds ratios (ORs). RESULTS: Over a 12-year period, 425 patients (640 flaps) had prior abdominal surgery, and 393 patients (547 flaps) had no prior abdominal surgery. Of the patients with previous abdominal surgery, 67 (15.7%) underwent preoperative CTA and 333 (78.4%) did not. Patients with prior abdominal surgery were more likely to have donor-site wound complications (OR: 1.82, 95% confidence interval [CI]: 1.15-2.87, p = 0.01), fat necrosis ≥2cm of the transferred flap (OR: 1.39, 95% CI: 1.0-1.94, p = 0.05), and were more likely to have bilateral DIEP flap reconstruction (OR: 1.61, 95% CI: 1.22-2.12, p < 0.001). Preoperative CTA did not reduce the risk of complications and did not affect operative times. CONCLUSION: DIEP flap reconstruction can be safely performed in women with prior abdominal surgery. However, these patients should be counseled that they are at an increased risk for donor-site wound breakdown and fat necrosis of the reconstructed breast. Preoperative CTA does not reduce complication rate, overall operative time, or time needed to dissect perforators in women with abdominal scars.

Deep Inferior Epigastric Artery Perforator Flap Breast Reconstruction in Women With Previous Abdominal Incisions: A Comparison of Complication Rates.

BACKGROUND: The deep inferior epigastric artery perforator (DIEP) flap is currently the most widely used method for autologous microsurgical breast reconstruction. There are mixed data in the literature regarding the impact of previous abdominal surgery on DIEP flap success in breast reconstruction. With this study, we take a closer look at the effect of prior abdominal surgery on DIEP flap and donor-site complications, with a particular focus on the different types of incisions and their influence on surgical outcomes. METHODS: A retrospective cohort study was conducted over a 6-year period. Five hundred forty-four consecutive DIEP flaps were divided into a control group (321 flaps) without previous abdominal surgery and an incision group (223 flaps) with previous abdominal surgery. A comparison between both groups was made in terms of flap and donor-site complications followed by a subgroup analysis based on single types of abdominal incisions. RESULTS: There were no significant differences between both groups in terms of age, body mass index, flap weight, smoking history, prior radiotherapy, diabetes, and coagulopathy (P > 0.05). The most common incision was low transverse incision (n = 116) followed by laparoscopy port (n = 103) and midline (n = 46) incisions. We found no significant differences between the control group and incision group in terms of flap complications. Subgroup analysis revealed that none of the 3 types of incision increase the flap or donor-site complications. Smoking and flap weight were the only 2 independent predictors for donor-site complications. CONCLUSIONS: The results from this large series of consecutive DIEP flaps from our institution confirm that autologous breast reconstruction with DIEP flap can be safely performed in patients who have had previous abdominal surgeries; however, counseling patients about smoking is critical to avoid potential donor-site complications.

Chronic Scapholunate Interosseous Ligament Disruption: A Systematic Review and Meta-Analysis of Surgical Treatments.

Background: Although many techniques have been described, there is no clear optimal surgical treatment for chronic scapholunate interosseous ligament (SLIL) disruption. Methods: We identified 255 articles reporting outcomes of SLIL reconstruction. Of these, 40 studies (978 wrists) met eligibility requirements and reported sufficient data on radiographic outcomes to be included in the study. The mean and standard deviation of preoperative and follow-up assessments including scapholunate gap (SLG) and scapholunate angle (SLA) were used to calculate pooled standardized mean differences (SMD) with 95% confidence intervals (CIs). For other radiographic or clinical outcomes, there were not enough reported data to calculate a pooled effect size, and pooled nonstandardized comparisons were made. Results: The SMD between preoperative and postoperative SLA in tenodesis reconstruction was 0.7 (CI, 0.29 to 1.11, P = .001) and 0.04 (CI, -0.27 to 0.38, P = .8) for capsulodesis reconstruction. For SLG, tenodesis demonstrated an SMD of 1.1 (CI, 0.6 to 1.55, P < .001) compared with 0.1 (CI, -0.36 to 0.59, P = .6) for capsulodesis reconstruction. Tenodesis had a significant improvement compared with capsulodesis in SLA (P = .01) and SLG (P = .005). Tenodesis also showed improvement in grip strength and Disabilities of the Arm, Shoulder and Hand scores. Conclusions: Comparing preoperative and postoperative radiographic measurements, tenodesis reconstruction demonstrated significantly improved SLG and SLA relative to capsulodesis. Interpreted in the context of the limitations, existing data demonstrates some benefit of tenodesis reconstruction.

Reconstruction of Lumbar Spinal Defects: Case Series, Literature Review, and Treatment Algorithm.

BACKGROUND: Lumbar spinal defects present a distinct challenge for the reconstructive surgeon and are often complicated by previous spinal surgery, the presence of hardware, and prior radiation. There are a variety of reconstructive options described but no clear treatment algorithm for these challenging defects. METHODS: A literature search was performed to review the described treatment options for lumbar spinal soft-tissue defects. Treatments for myelomeningocele or pressure ulcers were excluded. In addition, a retrospective case review was performed for patients with lumbar defects treated with pedicled superior gluteal artery perforator (SGAP) flap reconstruction. RESULTS: A literature review revealed 2,022 articles pertaining to lumbar defect reconstruction, of which 56 met inclusion criteria. These articles described 13 individual reconstructive techniques for this anatomic area. The most commonly described techniques were evaluated and a treatment algorithm designed based on patient and wound characteristics. The clinical course of 5 patients with radiated lumbar spinal defects treated with SGAP flaps is presented. CONCLUSIONS: There are many treatment options for lumbar spinal defects and treatment should be tailored to the patient and the characteristics of the defect. For large or radiated lumbar wounds, the pedicled SGAP flap is an excellent reconstructive choice, as it has reliable anatomy that is outside the zone of injury, adequate bulk, and minimal donor-site deficits.
