3D PED BURN app: A precise and easy-to-use pediatric 3D burn surface area calculation tool.

Background and aimsCalculating the precise total burn surface area is crucial when treating burn patients, particularly children. The Lund and Browder chart and Rule of Nines, 2-dimensional diagrams that are widely used, are subject to high interrater variance, and they can severely overestimate the burn area. Previously, the adult 3-dimensional burn area calculation mobile application was developed. Aiming to improve accuracy, a 3-dimensional pediatric burn surface area calculation mobile application ("3D PED BURN") was developed to overcome the limitations of the conventional methods.MethodFifteen 3-dimensional pediatric burn surface area models based on detailed anthropometric measurements collected from 85 patients were developed and categorized into four age groups: ResultA precise and easy-to-use application was developed based on these data. This application is a promising and more accurate calculation tool for burn surface area in pediatric patients. Its low inter-rater variance makes it reliable for use by various healthcare personnel.ConclusionThe 3D PED BURN app is a pediatric 3D burn surface area calculation tool that is both accurate and simple to use

Sternocleidomastoid muscle flap in preventing Frey's syndrome after parotidectomy: A systematic review

Background Parotidectomy is a common procedure and Frey's syndrome (gustatory sweating) is a common side effect. The current literature was assessed concerning the effectiveness of the sternocleidomastoid muscle (SCM) flap to prevent Frey's syndrome after parotidectomy. Methods A bibliography search was conducted for studies published between 1966 and 2010 and included randomized controlled trials (RCTs) or cohort studies with patients undergoing parotidectomy with facial nerve preservation. The outcome measures of particular interest were the incidence of Frey's syndrome and cosmetic impairment. Results In all, 12 studies were selected (1 meta‐analysis of all interventions to prevent Frey's syndrome, 2 RCTs, and 9 cohort studies). The trials were too heterogeneous to perform a meta‐analysis on the effect of the SCM flap. The results reported by the authors of each study suggest an objective decrease in Frey's syndrome when the SCM flap was used, but there was no difference in the patients' subjective reporting of symptoms. However, this conclusion is prone to the biases inherent in these studies, and thus overall it is impossible to make any recommendation. Conclusion Current reported evidence is inconclusive as to the use of SCM muscle flap as an intervention to prevent Frey's syndrome following parotid surgery. © 2011 Wiley Periodicals, Inc.

The masseteric nerve: An anatomical study in Thai population with an emphasis on its use in facial reanimation

Summary: Background: The use of the masseteric nerve has been escalated as a donor nerve for facial reanimation in facial palsy patient (Wang et al., 2014; Manktelow et al., 2006; Klebuc, 2011; Bianchi et al., 2012; Zuker et al., 2000; Bae et al., 2006; Terzis, Konofaos, 2013; Terzis, Olivares, 2009; Bianchi et al., 2014). Previous studies had been done in Euro-Caucasian cadavers (Kaya et al., 2014). However, difference in anatomical details does exist between Asian and Euro-Caucasian population (Tzou et al., 2005; Farkas et al., 2005). In this study, we have conducted a detailed anatomical study of masseteric nerve in adult Thai cadavers which might elaborate better details of masseteric nerve anatomy in Asian population. Methods: Twenty eight hemifaces from 14 adult Thai non-formaldehyde preserved soft cadavers were used in this study. The anatomical pathway of the masseteric nerve was defined relating to four surgical landmarks which are auricular tragus, zygomatic arch, posterior border of the temporomandibular joint, and alar base. Results: The suitable starting area for the masseteric nerve dissection is 3.7 ± 0.4 cm anterior to the auricular tragus at the level of 0.8 ± 0.2 cm inferior to the zygomatic arch. The nerve was found 1.1 ± 0.2 cm deep to the superficial surface of the masseteric fascia and 1.7 ± 0.2 cm anterior to the posterior border of the temporomandibular joint. The point where the nerve giving off its first branch as it courses distally is 7.3 ± 0.7 cm from the ipsilateral alar base. The mean diameter of this nerve is 1.59 ± 0.42 mm. Conclusion: The anatomy of the masseteric nerve during its course in the muscle is consistent. In our study, the details of its anatomy is slightly different from the previous works which were performed in the Euro-Caucasian cadavers.

Randomized Clinical Trial of the Innovative Bilayered Wound Dressing Made of Silk and Gelatin: Safety and Efficacy Tests Using a Split-Thickness Skin Graft Model

We developed the novel silk fibroin-based bilayered wound dressing for the treatment of partial thickness wounds. And it showed relevant characteristics and accelerated the healing of full-thickness wounds in a rat model. This study is the clinical evaluation of the bilayered wound dressing to confirm its safety and efficacy for the treatment of split-thickness skin donor sites. The safety test was performed using a patch model and no evidence of marked and severe cutaneous reactions was found. The efficacy test of the bilayered wound dressing was conducted on 23 patients with 30 split-thickness skin graft donor sites to evaluate healing time, pain score, skin barrier function, and systemic reaction in comparison to Bactigras. We found that the healing time of donor site wounds treated with the bilayered wound dressing (11 ± 6 days) was significantly faster than those treated with Bactigras (14 ± 6 days) (p=10-6). The wound sites treated with the bilayered wound dressing showed significantly less pain and more rapid skin functional barrier recovery than those treated with Bactigras (p=10-5). Therefore, these results confirmed the clinical safety and efficacy of the bilayered wound dressing for the treatment of split-thickness skin graft donor sites

The Role of Negative-Pressure Wound Therapy in Latissimus Dorsi Flap Donor Site Seroma Prevention: A Cohort Study

Background Donor site seroma is the most common complication after latissimus dorsi (LD) flap harvest. This study aimed to evaluate the efficacy of negative-pressure wound therapy (NPWT) in preventing donor site seroma formation after the harvest of an LD flap for breast reconstruction. Methods In this prospective matched-pair study, 40 patients in whom an LD flap was harvested for breast reconstruction were enrolled. NPWT was used in 20 patients, and in a control group composed of another 20 patients, the conventional donor site dressing technique was used. Information was collected regarding postoperative complications, the incidence of seroma, total drainage volume, the number of percutaneous seroma aspirations, and the volume aspirated. Results In the NPWT group, the incidence of seroma formation after drain removal was significantly lower than in the control group (15% vs. 70%; odds ratio=0.07; relative risk, 0.24). Both the mean percutaneous aspirated volume (P=0.004) and the number of percutaneous aspirations (P=0.001) were also significantly lower in the NPWT group. There were no significant differences in the total drainage volume or the duration of wound drainage between the NPWT dressing group and the control group (P>0.05). Conclusions This study showed that NPWT is a promising tool for reducing the incidence of seroma formation after removing the drain at the donor site after LD flap harvesting. It is a simple and safe technique
