Objective@#To analyze growth changes in the ear by measuring the width and length of ears in a Chinese population and its application for auricular reconstruction.@*Methods@#A total of 480 participants were enrolled into 1 year, 3 years, 5 years, 7 years, 9 years, 12 years, 14 years and adult groups (half were boys and half were girls in each group). Ear length and width were measured and recorded. Ear index was calculated according to ear length and ear width. The growth of auricle and differences between genders were analyzed.@*Results@#Ear length and width increased with age. Ear length achieved its mature size in both 14-year-old males and females. Ear width reached its mature size in males of 7 years and in females of 5 years. Different trends of ear index were shown between males and females.@*Conclusions@#The data indicated that ear developed with age. There were gender and ethnic difference in the development of ear. Ear reconstruction should not be performed when the age of patient is less than 12 years old, if only the development of ear width is considered, the age of patient for surgery to be performed should not be less than 7 years old.
RÉSUMÉ
OBJECTIVE@#To explore the possible mechanism of brain damage and memory impairment in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) by detecting the memory, serum S100beta protein, neuron specific enolase( NSE) and analyzing the relationship among them.@*METHOD@#Thirty patients with moderate or severe OSAHS (AHI > 20/h) and twenty normal controls were included in this study. All subjects were detected by polysomnography in the sleep laboratory and the memory of them were evaluated before PSG examination. Memory tests including point memory, association learning, picture free recall, meaningless picture recognition, face characters associated memory have been conducted. The serum S100beta protein was detected by ELISA and the serum NSE was detected by immunoradiometric assay. The relationship between memory and serum S100beta as well as NSE were analyzed in both experiment group and control group.@*RESULT@#The score of point memory, association learning, meaningless picture recognition, face characters associated memory and memory quotient in patients with OSAHS was significantly lower than control group (P < 0.05). The serum S100beta and NSE level was significantly higher than control group (P < 0.05); and correlated positively with AHI as well as ODI; and correlated negatively with MSaO2. Memory quotient correlated negatively with AHI, ODI, serum S100beta and NSE level; and correlated positively with LSaO2, MSaO2.@*CONCLUSION@#Memory impairment were present in patients with OSAHS. The increased level of serum S100Beta and NSE may be one of the mechanisms of brain damage and memory impairment in with, OSAHS. And nocturnal hypoxia may contribute to the increased level of serum S100beta and NSE.
