The few pathogens detected were mainly affected by the microbial source on the sampling day, regardless of pollution level. RDA (redundancy analysis) showed that the bacterial community was positively correlated with the concentration of particulate matter and that the wind speed in spring was positively correlated with NO3- levels, NH4+ levels, temperature, and relative humidity in summer and autumn, but there was no clear consistency among winter samples. This study comprehensively analyzed the variations in the characteristics of the airborne bacterial community in Beijing over one year and provided a reference for understanding the source, mechanism, and assessment of the health effects of different air qualities. Ear congenital deformities represent an aesthetical concern in adult patients and a social matter in children. An accurate assessment of ear defects should be made preoperatively in order to plan surgery adequately. In order to correctly assess the ear preoperatively the authors have considered four different subunits helical and scaphal region (A), antihelical region (B), conchal region (C) and lobule region (D). Surgical planning should start from sub-unit A evaluation, ending with sub-unit D, in a concentric fashion. When sub-unit A defects have to be corrected, an anterior approach is preferred. A correct evaluation of ear defects prior to surgery is of dramatic importance. Sub-unit A ear defects are often disregarded, and surgical techniques for their correction are rarely considered. Correcting helical and scaphal defects requires an anterior approach, influencing the technique employed for the correction of subunits B and C defects. Sub-unit B defects should be evaluated and corrected before sub-unit C defects in order to avoid overcorrection of ear protrusion. Several surgical techniques have been
