Background: Acute otitis media (AOM) causes inflammation and hearing loss. Ventilation tubes are key in treatment. 3D printing improves prostheses in otorhinolaryngology, offering precision and greater adaptability.
Materials And Methods: An experimental study was conducted with Wistar rats from July to December 2020. 3D tympanostomy tube models were designed, with technical specifications and tests performed on inexpensive 3D printers. The tympanostomy tube was inserted endoscopically.
Results: Procedures were performed on five rats with implants in both ears. Pre-intervention pathologies, such as atical retraction and glue ear, were found. The PLA-printed tympanostomy tube showed improvement after adjustments. Histopathological results revealed significant middle and inner ear damage.
Conclusion: In our study, the design and 3D printing of implants fulfilled the desired functions when modified, with a height of 5 mm. Complications included PLA degradation and ear damage. There were no adverse events during observation, highlighting the need for further research on 3D-printed implants.

Objective: Assess the long-term outcome of pediatric myringoplasty.
Methods: Tympanoplasty type I, myringoplasty, was performed on 85 children (91 consecutive operations, 74 primary and 17 revisions) under 16 years of age. The perforations were sequela either to acute or chronic inflammatory middle ear disease.

Objective: Aim: To improve the effectiveness of surgical treatment for patients with post-traumatic tympanic membrane perforations and concurrent Eustachian tube dysfunction through simultaneous combined surgical methods.
Patients And Methods: Materials and Methods: We analyzed clinical and functional outcomes of 35 patients (mean age: 34 ± 10,5 years) with tympanic membrane perforations caused by acoustic and blast injuries. The patients were divided into two groups: the first group (n=17) underwent only tympanoplasty type 1, while the second group (n=18) underwent simultaneous septoplasty, inferior turbinectomy, and tympanoplasty with prolonged middle ear ventilation using a subanular Silverstein tube.

Background: Achondroplasia, the most prevalent form of skeletal dysplasia involving short stature, necessitates a multidisciplinary approach that includes otology and auditory rehabilitation. Despite this, the clinical characteristics of hearing loss and otologic manifestations in achondroplasia patients remain poorly defined. This study aimed to explore the prevalence and treatment outcomes of otologic disease in individuals with achondroplasia.

Objective: To assess the efficacy of combined tympanostomy tube insertion (TTI) and adenoidectomy (Ad) Ad alone in the treatment of otitis media with effusion (OME) in children.
Methods: Clinical data of 145 children with OME who underwent surgical treatment in Jiaxing University Affiliated TCM Hospital from January 2022 to November 2023, were retrospectively analyzed. Patients were grouped based on whether or not Ad was performed with TTI: children who underwent Ad alone were grouped as Ad group (n=71), and children who underwent a combined TTI and Ad were grouped as TTI+Ad group (n=74).
