More and more studies have shown that relevant cell proliferation and inflammation progression pathways play a role in the development of otitis media, such as the Jun amino-terminal protein kinase (JNK) mitogen-activated protein kinase (MAPK) signaling pathway, the NF-κB signaling pathway, and the PI3K/AKT/PTEN pathway, which are involved in the proliferation of the middle ear mucosa during otitis media, which affects the mucosal cilia, motor function, Eustachian tube function, and the mucosal ciliary function. These studies provide new ideas for the treatment of otitis media and further explore the feasibility of immunotherapy in the future treatment of otitis media. In this paper, we present a review of the latest research progress on the expression of various cytokines in otitis media.展开更多

Methods This reasarch measures for the Eustachian tube opening pressure by injection of surface active substance into middle ear space, studying the effect of surfactant on Eustachian tube opening function. Results It has been showed that the injection of killed streptococcus pneumoneac bacteria by the transtympanic route, successfully developed a secretory otitis media model. Eustachian tube opening pressure in ears with SOM was significantly greater than those without effusion ( P <0.01). Irrigation the middle ear space with surfactant resulted in a dramatic decrease in eustachian tube passive opening pressure in both normal and patients ( P <0.01). Conclusion The results indicate that flushing with exogenous surfactant by the transtympanic rote reduce of eustachian tube surface tension, and it benefits the Eustachian tube opening.展开更多

Materials and Methods: A prospective study of the cases of tubotympanic type of chronic suppurative otitis media was undertaken. Patients were subjected to clinical examination followed by audiometry tests and impedence audiometry to determine eustachian tube functions. Patients were then subjected to myringoplasty and eustachian tube function were then reassessed post operatively. Results: In our study, out of 30 cases who underwent myringoplasty, 21 cases had successful surgical outcome and 9 cases were failed. Out of 24 cases of good Eustachian tube function, 21 cases had successful surgical outcome intends of taking up graft, absence of otorrhea and improvement in hearing. In remaining 3 cases, there was recurrence of otorrhea with central perforation. All the 6 cases with poor Eustachian tube function had surgical failure. Conclusion: The prognosis of the middle ear reconstructive surgery has direct correlation with Eustachian tube functions and Eustachian tube function tests should be a routine investigation in all the cases planned for surgical reconstruction of the middle ear.展开更多
Objective: To report outcomes of balloon dilation Eustachian tuboplasty combined with tympanostomy tube insertion and middle ear pressure equalization therapy in treatment of recurrent secretory otitis media. Methods:...Objective: To report outcomes of balloon dilation Eustachian tuboplasty combined with tympanostomy tube insertion and middle ear pressure equalization therapy in treatment of recurrent secretory otitis media. Methods: Fifty one patients with recurrent secretory otitis media (62 ears) underwent balloon dilation of Eustachian tube and tympanic tube insertion under general anesthesia, followed by long term middle ear pressure equalization therapies. The Eustachian tube score (ETS) and Eustachian tube function questionnaire (ETDQ-7) were used for pre- and postoperative (up to 12 months) evaluation of Eustachian tube functions. Results: The mean ETS score was 2.34 ± 0.97 preoperatively, and 6.17 ± 1.54, 7.23 ± 1.62, 8.24 ± 1.97, and 7.63 ± 1.86 at 1, 3, 6 and 12 months postoperatively, respectively (P < 0.05). The ETDQ-7 score was 4.82 ± 1.07 preoperatively, and 2.20 ± 0.54, 2.32 ± 0.68, 2.53 ± 0.79, and 2.67 ± 0.76 at 1, 3, 6 and 12 months postoperatively, respectively (P < 0.05). Conclusion: Balloon dilation of Eustachian tube combined with tympanostomy and catheterization resulted in significant improvement of subjective symptoms and objective evaluation of Eustachian tube functions in most patients with recurrent secretory otitis media, as indicated by the ETS and ETDQ-7 scores, demonstrating high levels of efficacy and patient satisfaction.展开更多
