Complications of tissue expansion in a public hospital [Case Report]

Youm T; Margiotta M; Kasabian A; Karp N
Avoidance of complications in tissue expansion requires careful outpatient observation and consistent follow-up-two factors that are difficult to manage in a city hospital-based population. To determine the complication rate of tissue expanders in a given population, the authors reviewed retrospectively 34 tissue expanders placed in 30 patients at a New York City public hospital over a 7-year period from 1989 to 1996. The mean age of the patients at the time of insertion was 25 years (range, 11 months-65 years). The most common conditions for treatment were nevi (N = 11), burn scars (N = 8), breast reconstructions (N = 8), and spina bifida (N = 4). Complications occurred in 22 of 34 expanders (65%). Complications included deep infection (N = 11), exposure (N = 7), breakdown of the surgical wound (N = 4), cellulitis (N = 3), drainage (N = 1), and deflation (N = 1). Major complications resulted in premature removal in 13 of 34 expanders (38%). Minor complications leading to successful completion of the expansion process occurred with 9 of 34 expanders (27%). No complications were recorded in the remaining 12 of 34 expanders (35%). Although tissue expansion is a potentially safe and effective method of reconstruction, this review should alert the surgeon to the distinct challenges that may be encountered in the public hospital

Risk factors for excess mortality in Harlem. Findings from the Harlem Household Survey

Fullilove, R E; Fullilove, M T; Northridge, M E; Ganz, M L; Bassett, M T; McLean, D E; Aidala, A A; Gemson, D H; McCord, C
INTRODUCTION: In 1980, age-adjusted mortality rates in Central Harlem were the highest among New York City's 30 health districts. This population-based study was designed to describe the self-reported frequency of selected health conditions, behavioral risk factors, preventive health practices, and drug use in the Harlem community. METHODS: From 1992 to 1994, in-person interviews were conducted among 695 adults aged 18 to 65 years who were randomly selected from dwelling-unit enumeration lists for the Central Harlem health district. Descriptive statistics were computed for men and women separately, and compared to other population-based surveys. RESULTS: Self-reported medical insurance coverage in Harlem was unexpectedly high (74% of men, 86% of women) as was lifetime use of preventive health practices, e.g., blood cholesterol screening (58% of men, 70% of women). However, lifetime rates of substance use, e.g. crack cocaine (14%) and self-reported history of traumatic events, e.g., witnessing someone seriously injured or violently killed (49% of men, 21% of women) were also high in Harlem, especially in comparison to other populations. CONCLUSIONS: This study has identified important patterns of similarities and differences in risk behaviors between Harlem and other populations. Potential solutions to the health problems of Harlem may lie in the creation of strategies that operate at the community, municipal, and regional level, as well as at the level of individual behavior and risk-taking.

Optimal time for distraction osteogenesis in limbs with nerve repairs: experimental study in the rat

Vekris, M D; Bates, M; Terzis, J K
The optimal period of time between peripheral-nerve repair and initiation of limb lengthening procedures has never been precisely determined. In the clinical setting, the surgeon must decide how long the repaired nerves should be allowed to heal before subjecting them to the forces created by the limb-lengthening process. The authors designed a study to quantify and qualify the effects of different recovery periods between initial nerve repair and subsequent limb-lengthening via distraction osteogenesis. Forty-two Sprague-Dawley male rats were randomized in two different categories of nerve repair: end-to-end and nerve grafts. At 4, 8 and 12 weeks after nerve reconstruction, the femur was submitted to limb-lengthening at a rate of 1 mm/day (0.25 mm every 6 hr). Sciatic Function Index (SFI) evaluation indicated that the impact of distraction was detrimental in the grafted nerves, although they maintained their electrical and morphologic properties at comparable levels to the non-distracted nerves. Nerves with direct coaptation presented an overall superior regeneration pattern. The findings in end-to-end repairs distracted at 8 weeks and those of grafted nerves at 12 weeks were comparable to those in distracted normal nerves. The morphology of the distracted nerves appeared to be more organized than that observed in the non-distracted nerves

Distraction osteogenesis of the mandible: a ten-year experience

McCarthy JG; Stelnicki EJ; Grayson BH
Mandibular distraction has been performed at the authors' institution for the past 10 years on a variety of craniofacial anomalies. This article reviews the experience with distraction and outlines the authors' treatment algorithms based on patient age and pathology. The roles of distraction versus conventional orthognathic surgery are reviewed. The need for preoperative surgical planning and postoperative orthodontic therapy is emphasized

Treatment planning and biomechanics of distraction osteogenesis from an orthodontic perspective [Case Report]

Grayson BH; Santiago PE
As in traditional combined surgical and orthodontic procedures, the orthodontist has a role in the planning and orthodontic support of patients undergoing distraction osteogenesis. This role includes predistraction assessment of the craniofacial skeleton and occlusal function in addition to planning both the predistraction and postdistraction orthodontic care. Based on careful clinical evaluation, dental study models, photographic analysis, cephalometric evaluation, and evaluation of three-dimensional computed tomographic scans, the orthodontist, in collaboration with the surgeon, plans distraction device placement and the predicted vectors of distraction. Both surgeon and orthodontist closely monitor the patient during the active distraction phase, using intermaxillary elastic traction, sometimes combined with guide planes, bite plates, and stabilization arches, to mold the newly formed bone (regenerate) while optimizing the developing occlusion. Postdistraction change caused by relapse is minimal. Growth after mandibular distraction is variable and appears to be dependent on the genetic program of the native bone and the surrounding soft tissue matrix. A significant advantage of distraction osteogenesis is the gradual lengthening of the soft tissues and surrounding functional spaces. Distraction osteogenesis can be applied at an earlier age than traditional orthognathic surgery because the technique is relatively simple and bone grafts are not required for augmentation of the hypoplastic craniofacial skeleton. In this new technique, the surgeon and the orthodontist have become collaborators in a process that gradually alters the magnitude and direction of craniofacial growth

Nasal expansion in the fetal lamb: a first step toward management of cleft nasal deformity in utero

Levine JP; Bradley JP; Shahinian HK; Longaker MT
The cleft nasal deformity, a combination of malpositioned cartilage and tissue and postrepair scarring, is a difficult problem to correct. To harness the potential of scarless fetal wound healing, in utero repair of cleft lip and palate deformities has been studied but the fetal cleft nose deformity has not been addressed. The purpose of this study was to manipulate the fetal nasal shape in utero as a first step toward restoration of normal nasal form in cleft nasal deformities. To do this, preformed hypertonic sponges were placed into the right nostril of eight fetal lambs during the second trimester (when scarless cutaneous wound repair is known to occur). Then, the size and shape of fetal nasal structures were analyzed after selected time periods (1, 2, and 6 weeks) with measurements, routine histologic examination, and three-dimensional computed tomographic scans of the experimentally expanded noses compared with the control nonexpanded noses of the birth twins or age-matched specimens. Results showed that experimentally expanded nasal structures had markedly increased in septal length measurement, in nostril area (doubled), and in intranasal volume (more than doubled). Histology showed normal cellular elements without scarring in the tissue sections from the expanded nasal areas. In conclusion, the shape of nasal tissue can be manipulated without scarring in second-trimester fetal lambs after placement of a nasal expansion device. This study is an experimental first step toward restoring normal nasal form by repositioning alar cartilages and soft tissue during fetal cleft repair
