The conchal butterfly graft in secondary reconstruction of the bilateral cleft lip nasal deformity.

OBJECTIVES: The bilateral cleft nasal deformity is characterized by a short columella and a broad, flattened nasal tip. Secondary correction is challenging and often complicated by skin envelope scarring and hypoplastic alar cartilages. Adequate and durable tip projection requires a procedure that adequately augments the nasal tip and maximizes tip support. We describe a novel technique for secondary correction of this deformity in the immature pediatric population. METHODS: The conchal butterfly graft technique utilizes a folded cartilage construct to simultaneously increase tip projection and provide tip support. A retrospective review of 19 consecutive patients with bilateral cleft lip who underwent secondary tip rhinoplasty utilizing our technique over a 7-year period was conducted. Charts were reviewed for age at operation, length of follow-up and secondary revision procedures. Pre- and post-operative photographs were compared using two different methods to assess the degree of change and overall aesthetic result. Three plastic surgeons who previously were unfamiliar with the technique independently rated seven nasal tip characteristics. Nasal tip projection (NTP) was then measured objectively by two widely utilized methods: the Goode method and the Baum method-modified by Powell. RESULTS: Long lasting correction of the bilateral cleft nasal deformity was achieved utilizing this technique in 19 patients over a 7-year period with a mean length of follow-up of 5.4 years. We demonstrate augmented nasal tip projection that approaches ideal relationships from both relative measurement and survey data. CONCLUSION: The conchal butterfly graft technique is effective for reconstruction of the bilateral cleft nasal deformity, and in our experience, has resulted in long lasting nasal projection and overall improved facial balance.

Effects of a Fibrin Sealant on Skin Graft Tissue Adhesion in a Rodent Model.

OBJECTIVE: To establish a rodent model for skin grafting with fibrin glue and examine the effects of fibrin glue on the adhesive strength of skin grafts without bolsters. STUDY DESIGN: Animal cohort. SETTING: Academic hospital laboratory. SUBJECTS AND METHODS: Three skin grafts were created using a pneumatic microtome on the dorsum of 12 rats. Rats were evenly divided into experimental (n = 6) and control (n = 6) groups. The experimental group received a thin layer of fibrin glue between the graft and wound bed, and the control group was secured with standard bolsters. Adherence strength of the skin graft was tested by measurement of force required to sheer the graft from the recipient wound. Adhesion strength measurements were taken on postoperative days (PODs) 1, 2, and 3. RESULTS: The experimental group required an average force of 719 g on POD1, 895 g on POD2, and 676 g on POD3, while the average force in the control group was 161 g on POD1, 257 g on POD2, and 267 g on POD3. On each of the 3 PODs, there was a significant difference in adherence strength between the experimental and control groups (P = .036, P = .029, P = .024). CONCLUSION: There is a significant difference in the adhesion strength of skin grafts to the wound bed in the early postoperative period of the 2 groups. In areas of high mobility, using the fibrin sealant can keep the graft immobile during the critical phases of early healing.

Predicting the need for muscle flap salvage after open groin vascular procedures: a clinical assessment tool.

Groin wound complications after open vascular surgery procedures are common, morbid, and costly. The purpose of this study was to generate a simple, validated, clinically usable risk assessment tool for predicting groin wound morbidity after infra-inguinal vascular surgery. A retrospective review of consecutive patients undergoing groin cutdowns for femoral access between 2005-2011 was performed. Patients necessitating salvage flaps were compared to those who did not, and a stepwise logistic regression was performed and validated using a bootstrap technique. Utilising this analysis, a simplified risk score was developed to predict the risk of developing a wound which would necessitate salvage. A total of 925 patients were included in the study. The salvage flap rate was 11.2% (n = 104). Predictors determined by logistic regression included prior groin surgery (OR = 4.0, p < 0.001), prosthetic graft (OR = 2.7, p < 0.001), coronary artery disease (OR = 1.8, p = 0.019), peripheral arterial disease (OR = 5.0, p < 0.001), and obesity (OR = 1.7, p = 0.039). Based upon the respective logistic coefficients, a simplified scoring system was developed to enable the preoperative risk stratification regarding the likelihood of a significant complication which would require a salvage muscle flap. The c-statistic for the regression demonstrated excellent discrimination at 0.89. This study presents a simple, internally validated risk assessment tool that accurately predicts wound morbidity requiring flap salvage in open groin vascular surgery patients. The preoperatively high-risk patient can be identified and selectively targeted as a candidate for a prophylactic muscle flap.

Timeliness and quality of surgical discharge summaries after the implementation of an electronic format.

BACKGROUND: As electronic discharge summaries (EDS) become more prevalent and health care systems increase their focus on transitions of care, analysis of EDS quality is important. The objective of this study was to assess the timeliness and quality of EDS compared with dictated summaries for surgical patients, which has not previously been evaluated. METHODS: A retrospective study was conducted of a sample of discharge summaries from surgical patients at an urban university teaching hospital before and after the implementation of an EDS program. Summaries were evaluated on several dimensions, including time to summary completion, summary length, and summary quality, which was measured on a 13-item scoring tool. RESULTS: After the exclusion of 5 patients who died, 195 discharge summaries were evaluated. Discharge summaries before and after EDS implementation were similar in admission types and discharge destinations of the patients. Compared with dictated summaries, EDS had equivalent overall quality (P = .11), with higher or equivalent scores on all specific quality aspects except readability. There was a highly significant statistical and clinical improvement in timeliness for electronic summaries (P < .01). Obvious use of copying and pasting was identified in 8% of discharge summaries and was associated with decreased readability (P = .02). CONCLUSIONS: The implementation of EDS can improve the timeliness of summary completion without sacrificing quality for surgical patients. Excessive copying and pasting can reduce the readability of discharge summaries, and strategies to discourage this practice without the use of appropriate editing should be used.

Using peers to assess handoffs: a pilot study.

BACKGROUND: Handoffs among post-graduate year 1 (PGY1) trainees occur with high frequency. Peer assessment of handoff competence would add a new perspective on how well the handoff information helped them to provide optimal patient care. OBJECTIVE: The goals of this study were to test the feasibility of the approach of an instrument for peer assessment of handoffs by meeting criteria of being able to use technology to capture evaluations in real time, exhibiting strong psychometric properties, and having high PGY1 satisfaction scores. DESIGN: An iPad® application was built for a seven-item handoff instrument. Over a two-month period, post-call PGY1s completed assessments of three co-PGY1s from whom they received handoffs the prior evening. PARTICIPANTS: Internal Medicine PGY1s at the University of Pennsylvania. MAIN MEASURES: ANOVA was used to explore interperson score differences (validity). Generalizability analyses provided estimates of score precision (reproducibility). PGY1s completed satisfaction surveys about the process. KEY RESULTS: Sixty-two PGY1s (100 %) participated in the study. 59 % of the targeted evaluations were completed. The major limitations were network connectivity and inability to find the post-call trainee. PGY1 scores on the single item of "overall competency" ranged from 4 to 9 with a mean of 7.31 (SD 1.09). Generalizability coefficients approached 0.60 for 10 evaluations per PGY1 for a single rotation and 12 evaluations per PGY1 across multiple rotations. The majority of PGY1s believed that they could adequately assess handoff competence and that the peer assessment process was valuable (70 and 77 %, respectively). CONCLUSION: Psychometric properties of an instrument for peer assessment of handoffs are encouraging. Obtaining 10 or 12 evaluations per PGY1 allowed for reliable assessment of handoff skills. Peer evaluations of handoffs using mobile technology were feasible, and were well received by PGY1s.

Effect of cataract surgery on the corneal endothelium: modern phacoemulsification compared with extracapsular cataract surgery.

PURPOSE: To investigate whether modern phacoemulsification surgery results in more damage to the corneal endothelium than extracapsular cataract extraction (ECCE), and to examine which preoperative, operative, and postoperative factors influence the effect of cataract surgery on the endothelium. DESIGN: Randomized controlled trial. PARTICIPANTS: Five hundred patients 40 years or older were randomized into 2 groups (ECCE, 249; phacoemulsification, 251). METHODS: Central corneal endothelial cell counts, coefficient of variation of cell size, and hexagonality were assessed before surgery and up to 1 year postoperatively. MAIN OUTCOME MEASURE: Endothelial cell count. RESULTS: Four hundred thirty-three patients completed the trial. The initial preoperative mean cell count for the entire sample was 2481 (standard error [SE]: 18.6), reduced at 1 year postoperatively to 2239 (SE: 23.5). An average 10% reduction in cell count was recorded by 1 year postoperatively. There was no such change in hexagonality or in the coefficient of variation. There was no significant difference in overall percentage cell loss between the 2 treatment groups. Factors associated with excessive cell loss (> or =15% by 1 year) were a hard cataract (odds ratio [OR]: 2.1, 95% confidence limits: 1.1-4.1; P = 0.036), age (OR: 1.04, P = 0.005), and capsule or vitreous loss at surgery (OR: 2.38, P = 0.106). Phacoemulsification carried a significantly higher risk (OR: 3.7, P = 0.045) of severe cell loss in the 45 patients with hard cataracts relative to ECCE (52.6% vs. 23.1%; chi-square test, P = 0.041), with both procedures achieving similar postoperative visual acuity outcomes. CONCLUSIONS: No significant difference in overall corneal endothelial cell loss was found between these 2 operative techniques. The increased risk of severe cell loss with phacoemulsification in patients with hard cataracts suggests that phacoemulsification may not be the optimal procedure in these cases, and that ECCE should be preferred.
