OBJECTIVE In the last several decades, there has been much debate regarding the ideal treatment for sagittal synostosis. The purpose of this study was to compare perioperative, anthropometric, and subjective assessments of cosmetic outcomes between open and endoscopic management of isolated sagittal synostosis. METHODS At their routine postoperative follow-up, pediatric patients with sagittal craniosynostosis were recruited to undergo digital cranial measurement and standardized photography for objective and subjective assessments of perioperative outcomes. Age-normalized z-scores for cephalic index, head circumference, euryon-euryon diameter (Eu-Eu), and glabella-opisthocranion diameter (G-Op) were calculated for each patient. Faculty surgeons, surgical trainees, nurses, and laypersons were asked to rate the normalcy of craniofacial appearances using a 5-point Likert scale. Outcomes were compared between patients treated with endoscopic correction and those treated with open repair. RESULTS A total of 50 patients were included in the study. Thirty-one had undergone open surgical correction, and 19 had undergone endoscopic treatment. Endoscopic repair involved significantly lower operative time, blood loss, transfusion rate, and hospital length of stay than those with open repair (p < 0.001). There was no significant difference between groups in terms of z-scores for head circumference (p = 0.22), cephalic index (p = 0.25), or Eu-Eu (p = 0.38). Endoscopic treatment was associated with a significantly lower G-Op (p = 0.009). Additionally, the average subjective rating of head shape was higher for endoscopic treatment when corrected for age, gender, and ethnicity (p = 0.02). CONCLUSIONS The study findings suggest that patients who are treated endoscopically may have an overall more normal appearance in skull morphology and cosmesis, although these results are limited by poor reliability.

Evolution Of Microstructure

In all fields of microscopy there is an increasing interest in the quantification of microstructure. This interest may stem from a desire to establish quality control parameters or may have a more fundamental requirement involving the derivation of parameters which partially or completely define the three dimensional nature of the microstructure. This latter categorey of study may arise from an interest in the evolution of microstructure or from a desire to generate detailed property/microstructure relationships. In the more fundamental studies some convolution of two-dimensional data into the third dimension (stereological analysis) will be necessary.In some cases the two-dimensional data may be acquired relatively easily without recourse to automatic data collection and further, it may prove possible to perform the data reduction and analysis relatively easily. In such cases the only recourse to machines may well be in establishing the statistical confidence of the resultant data. Such relatively straightforward studies tend to result from acquiring data on the whole assemblage of features making up the microstructure. In this field data mode, when parameters such as phase volume fraction, mean size etc. are sought, the main case for resorting to automation is in order to perform repetitive analyses since each analysis is relatively easily performed.

Third Dimension

The aim of presented paper was to create and subsequently apply the Modified 3D Creditworthy Model (MCWM) of performance reflecting sectoral characteristics and financial specificities of the selected sample of Slovak tour operators over the years 2013 – 2017. The intention of this research study was to implement the key financial indicators and appropriate prediction models into both dimensions of the traditional 2D Creditworthy Model of performance and to supplement its third dimension applying the selected modern assessment methods – the Economic Value Added and the Return On Net Assets as we consider them to be one of the most important indicators of future success and company's financial growth. This modification will help to better identify the current financial position of tour operators and more accurately identify causes that hinder the development of financial performance of the selected sample of enterprises. However, after adjusting the upper and lower quartile averages of a particular industry, this methodology is applicable in the wider context of enterprises, not only those operating in the tourism sector.
