Background & Objective: Efficacy of previous treatments on secretory otitis media ears with severely damaged eustachian tube function after radiotherapy is limited. Tympan perforation can avoid relapse of secretory otitis media. This study was to explore clinical value of incomplete tympanectomy for secretory otitis media in patients with nasopharyngeal carcinoma (NPC) after radiotherapy.
Methods: After confirmed severely damaged eustachian tube function through comprehensive examinations, 16 NPC patients (18 ears) with secretory otitis media after radiotherapy received incomplete tympanectomy. All patients were followed up for more than 6 months.
Results: After operation, 11 of 18 (61%) ears remained tympan perforation, audition was improved at large in these ears, the average air-bone conduction difference decreased from 30.1 dB to 16.0 dB, other symptoms, such as aural fullness, tinnitus, and headache, basically disappeared. After operation, tympans closed up in 7 (39%) ears,the average air-bone conduction difference decreased from 33.0 dB to 32.1 dB.
Conclusion: Incomplete tympanectomy may have a long and definite effect on secretory otitis media without any injury on audition after healing of tympan.

Objective: To investigate the effect of Mometasone furoate (Elocon Cream) Nasal Spray (MFNS) treatment on hearing secretory Otitis Media (SOM) in younger children.
Methods: Seventy-six children with SOM (ages 5 to 10 years-old) were selected as study subjects and divided into two groups of 38 cases each using a randomized numerical table. The control group was given conventional treatment, and the observation group was treated with MFNS based on the control group.

Objectives: In order to promote the use of AI technology as the auxiliary tool in pediatric otitis media diagnosis, we use the convolutional neural networks and deep learning for image classification and disease diagnosis. We also designed a Pediatric Otitis Media Classifier to analyze and classify the images for physicians.
Methods: A pediatric otitis media classifier was designed for junior physicians (doctors who have been engaged in clinical practice for a short time) as an auxiliary diagnostic tool.

Article Synopsis
- Allergic rhinitis (AR) is rising among children in Bayannur City, with a prevalence rate of 39.79%, highlighting a significant public health concern.
- A study surveyed 4,754 children and found various factors increasing AR risks, including being male, belonging to an ethnic minority, and having a history of allergies or frequent antibiotic use.
- Nearly half (48.78%) of the children affected reported that AR significantly impacted their studies or daily activities, and the condition is often associated with other allergic issues like asthma and dermatitis.

Congenital cholesteatoma is defined as a white mass behind an intact eardrum without a history of otitis media or previous otologic procedures. Congenital cholesteatoma is a relatively rare disease that accounts for about 2% to 5% of all cholesteatomas. However, the actual incidence rate of congenital cholesteatoma may be underestimated.

Background: The adenoids, primary sites of microbial colonization in the upper airways, can influence the development of various conditions, including otitis media with effusion (OME). Alterations in the adenoid microbiota have been implicated in the pathogenesis of such conditions.
Aim: This study aims to utilize 16S rRNA genetic sequencing to identify and compare the bacterial communities on the adenoid surfaces of children with OME and children with healthy middle ears.
