Radiological research of maxillary sinus development of children and adolescent without sinusitis in Kunming of Yunnan / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the maxillary sinus development and provide data for sinus surgery on children.@*METHOD@#Two thousand two hundred and thirty-eight children were randomly selected among those who underwent skull and nasal sinus CT scanning because of certain symptoms and signs. Patients were divided into eighteen age cohorts based on their age at the time of the scan. Anterior-posterior, transverse diameters and vertical height of the maxillary sinus were measured and statistically analyzed.@*RESULT@#The maxillary sinus volume was enlarging even in adult, hut the growth of maxillary sinus was relatively stable in adolescent. The difference of transverse and anterior-posterior diameters of maxillary sinus had no statistical significance between female and male (P > 0.05), while there was statistically significant difference in the vertical height of maxillary sinus (P < 0.05).@*CONCLUSION@#The results will aid the physicians when correlating the clinical and radiographic findings of pediatric patients who are being evaluated for sinus disease and potential surgical intervention.

Comparison of the nasal sinus development of children with or without sinusitis in Yunnan province / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the nasal sinus development and discuss the relation between sinusitis and nasal development.@*METHOD@#One thousand seven hundred and five healthy children and 1424 children with sinusitis were selected randomly. All children underwent naso sinus computer tomography. Sagittal, coronal and transverse diameters of all sinuses were measured and statistically analyzed.@*RESULT@#The measured sinus diameters of children with sinusitis were longer than that of healthy children (P < 0.01). Pearson analyses revealed a low correlation of age and the history of sinusitis (P < 0.01), and no correlation of gender and the history of sinusitis. There was moderate to high consistency between clinical diagnosis and nasal CT results about sinusitis (P < 0.01).@*CONCLUSION@#These results demonstrated that the differences of sinus development exist between the healthy children and children with sinusitis, and the sinus development in children with sinusitis were better than that of healthy children.

Research of the nasal sinusitis incidence of children in Kunming of Yunnan Province / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#In order to make a basis for the treatment of nasal sinuses of children and the correlated disease, we investigate the incidence rate of nasal sinusitis of children and explore the correlation between nasal sinusitis of children and CT in Kunming.@*METHOD@#Two thousand one hundred and fourteen healthy children and 1535 children with sinusitis were selected randomly. Form whom were undergone nasal sinus computer tomography for different medical reasons. The incidence rates of nasal sinusitis in different age-groups were calculated and statistically analyzed.@*RESULT@#The incidence rate of sinusitis was highest in 4 to 8 years old. There was moderate to high consistency between clinical diagnosis and nasal CT results (P<0.01).@*CONCLUSION@#These results demonstrate that the key stage of children's sinusitis prevention would be school-age children, and nasal CT scanning is helpful to evaluate the clinical condition.

Analysis of respiration events of sleep disordered breathing in children / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To analyze the characteristics of respiration events of sleep disordered breathing in children.@*METHOD@#Thirty-two guide polysomnography was monitored in 203 snoring children. According to AHI and AI, they were divided into five groups and the results were analyzed by polysmith.@*RESULT@#The mean value of REM was higher than that of NREM. The mean value between apnea and hypopnea have significant differences (P or = 1 need research.

Relationship between otoacoustic emissions and blood-lead levels in school children / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the relationship between blood levels of lead and the function states of cochlear outer hair cells (OHC).@*METHOD@#Two hundred and fifty-six children lived in Pb-Zn mine area and Yiliang country, aged from 6 to 7 years were enrolled in this study. Blood lead (B-Pb) levels were measured. Otoacoustic emission (OAE) tests including transient evoked otoacoustic emissions (TEOAE) and distortion products otoacoustic emission (DPOAE) were also measured in these children.@*RESULT@#The difference in B-Pb levels between the school children who lived in mine area and children lived in country was significant (P < 0.01). There were negative correlations between the B-Pb levels and the signal to noise ratio (SNR) on DPOAE test in children who lived in country and those lived in mine area (P < 0.01). The difference in relative coefficients of B-Pb levels between the children lived in mine and children lived in country were significant (P < 0.01).@*CONCLUSION@#The B-Pb levels of children who lived in mine area were higher than that of those lived in country. SNR decreased in plumbism cases. Long-term Pb expose may influence the function of cochlear OHC and higher B-Pb levels may lead to worse function of OHC.

Analysis of Fundamental Frequency and Voice Parameter From 4 to 8 Years Old Children / 听力学及言语疾病杂志

Objective To study and analyse the parameter values of voice in normal healthy preschool children and school-age children. Methods In present paper, voice quality of 120 cases were collected and analyzed with Dr. Speech software. Results There were no differences between preschool and school-age children on parameters jitter, shimmer, SNR, HNR, NNE, F 0, F 1,F 2,F 3 of voice acoustic and so in difference gender. Conclusion All parameters in preschool children and school-age children showed no difference. The tested parameters were significantly different between normal children and children with vocal nodule.
