Objective: To study the characteristics of wideband tympanometry(WBT) and its application value in the diagnosis of otitis media with effusion(OME) in young children. Methods: We compared wideband acoustic energy absorbance(EA) under peak pressure in young children with OME(190 ears) and healthy control subjects(121 ears) from Ninth People's Hospital of Shanghai Jiaotong University School of Medicine between January 2018 and June 2020. Both groups were divided into three groups, 1-6 months, 7-36 months and 37-72 months. SPSS 20.0 statistical software was used to analyze and compare the EA parameters between OME children of different months and the control group. Receiver operating characteristic (ROC)curve was used to analyze the diagnostic value of WBT in young children with OME. Results: There were significant differences in EA among three OME groups from 500 Hz to 2 000 Hz(P<0.05).Compared with the control groups, EA of 1-6 m OME group decreased significantly below 4 000 Hz(P<0.05), EA of 7-36 m OME group decreased significantly at 545-1 600 Hz(P<0.05), EA of 37-72 m OME group decreased significantly above 545 Hz(P<0.05).ROC curve indicated that EA at 1 000 Hz had the greatest diagnostic value (AUC was 0.890), followed by 1 500 Hz and the range of 500-2 000 Hz (AUC was 0.883 and 0.881, respectively).EA at 1 000 Hz with a cutoff value of 0.55 had the best diagnostic sensitivity of 90.8%, which was higher than conventional tympanometry (85.8%). The maximum AUC (0.932) could be obtained by combining EA, peak pressure and admittance amplitude of 226 Hz tympanometry as predictors. Conclusions: EA is significantly decreased in young children with OME. Compared with the conventional single frequency tympanometry, WBT is more accurate in the diagnosis of OME in young children, and the prediction accuracy would be better if combined with 226 Hz tympanometry.

7.Management of Otitis Media in Children.
Journal of the Korean Medical Association 2004;47(3):239-244
Otitls media is one of the most common diseases during childhood with a peak incidence and prevalence from 6 to 20 months of age. It is the most frequent disease managed with antibiotics in children. The infection typically develops as a result of bacterial contamination through the Eustachian tube in the presence of preexisting inflammation in the middle ear. The optimal method of management remains open to question and is the subject of continuing controversy. Over-diagnosis of the disease and unnecessary prescription of antibiotics for this condition have contributed to the spread of antimicrobial resistance. Thus, the differential diagnosis between acute otitis media and otitis media with effusion is important to determine the management strategy; whether to use antibiotics and which antibiotics to use when necessary. Otitis media may be accompanied by a variable degree of conductive hearing loss. Both infectious and noninfectious complications of otitis media may result in significant morbidity and complications, including acute and chronic mastoiditis, petrositis, and intracranial infection.

OBJECTIVETo explore evaluation strategies for middle ear dysfunction in cleft palate patients, to optimize the diagnosis and treatment of this dysfunction, and ultimately to improve the comprehensive treatment of cleft palate.
METHODSThe relationship among abnormal tympanic types (B, C, and Anomaly), effusion rate, tympanic pressure, and hearing loss were analyzed. We collected relevant information on 469 ears of cleft palate patients and traced one-year longitudinal changes in the tympana of 124 ears from 62 patients with both cleft lip and cleft palate.
RESULTSThe effusion rates of cleft palate patients with type B, type C, and type Anomaly were 50.3% (97/193), 34.8% (8/23), and 20.9% (53/253), respectively. The tympanic pressure of the ears with and without effusion showed no significant difference (P>0.05). The hearing loss in type B cleft palate patients with middle ear effusion was worse than that in patients without effusion (P=0.001). However, the hearing loss in type Anomaly showed no difference (P>0.05). The constituent ratio of each tympanic type remained constant during the period between cheiloplasty and palatoplasty for cleft lip and palate patients (P>0.05).
CONCLUSIONCleft palate patients of all tympanic types may all suffer from middle ear effusion at different rates. Examination by centesis is suggested for ears with abnormal tympanic types. Early aggressive therapy is essential for type B cleft palate patients with middle ear effusion to avoid hearing loss. However, catheterization may be not necessary for type Anomaly patients, and conservative observation should be performed instead. Myringotomy with grommet insertion during palatoplasty does not delay treatment timing for patients with both cleft lip and cleft palateg.

OBJECTIVETo evaluate the fluid in middle ear of otitis media with effusion (OME) by tympanometry, hearing threshold and in order to an effective and promptly way for treatment.
METHODSForty Patients (75 ears) with OME were collected since January 2007 to June 2008. The history of hearing loss, hearing threshold, CT results and the final fluid in the middle ear during operation were analyzed.
RESULTSThere were 28 males and 12 females enrolled in this study. The average age of the patients was 78 months. All the 75 ears were with type "B" according to tympanometry test. For all the patients myringotomy was performed and the ventilation tubes were placed in 23 ears. Among all the ears, there were fluid in 62 ears (82.7%) and no fluid in 13 ears (17.3%). There was correlation between the levels of hearing loss, CT results and the fluid in middle ear (P < 0.05).
CONCLUSIONSTympanometry and hearing threshold results should have a better sensitivity and specificity rates for diagnosis of OME.
