Otitis media with effusion (OME) was first described by Austrian otologist POLITZERZAI in 1867. The main feature is ear effusion and conductive hearing loss. However the etiology and pathogenesis of OME has not been clear up to now. It is thought that OME can be induced by upper respiratory infection,also can arise after radiotherapy of head and neck cancer. Presently the dysfunction of eustachian tube,infection of middle ear and allergic reaction are considered to be the major causes of OME. In recent years, more and more researches have concerned in immune response and otitis media with effusion.

Objective To explore the factors related to tympanic membrane perforation in children with acute suppurative otitis media,and to provide reference for clinical practice. Methods We reviewed the clinical data of 1274 children with acute suppurative otitis media from February 2017 to May 2020,and analyzed the factors related to tympanic membrane perforation. Results Tympanic membrane perforation occurred in 67 out of the 1274 children with acute suppurative otitis media,with the incidence of 5.27%.The univariate analysis showed that 11 factors including the duration of onset(

Tympanosclerosis is the middle ear tissue hyalinization and calcification caused by chronic middle ear inflammation, which mainly results in conductive deafness with unobvious clinical symptom. Etiology is unclear. The treatment is given priority to surgical treatment at present, while long-term effect reported mostly poor. This article analyzed etiology and treatment of the tympanic cavity sclerosis.

OBJECTIVE: The aim of this study is to investigate the incidence and natural history of secretory otitis media(SOM) and hearing loss in newborns and infants with cleft palate, consequently, define its audiological criteria and to predict SOM early. METHOD: Seventy-three newborns and infants with a cleft palate (146 ears) were monthly estimated by tympanogram, static compliance, acoustic stapedius reflex and auditory brainstem response (ABR) under natural sleep within one year of age. RESULT: Au the infants with cleft palate had the suspected SOM in the first 6 months of life. Among children with cleft palate, the suspected SOM were most prevalent in the 3-month-age. 78. 8% infants with cleft palate had the confirmed SOM in the first 12 months of life. SOM were most prevalent in the 6-month-age. The SOM prodromal period was averagely 3. 8 months from suspected SOM to confirmed SOM. 56. 2% infants with cleft palate had a conductive hearing loss in the first 12 months of life. The conduction hearing thresholds of ABR (2-4 Hz) were averagely 48. 6 dBnHL. CONCLUSION The highest incidence of SOM and hearing loss in children with cleft palate appear in infants in the first 1 year of life. The process of SOM and hearing loss onset is progressive process. The infants with cleft palate should be estimated by ABR and acoustic immittance audiometry in each period of 2 or 3 months after birth.

OBJECTIVE: The analyze the relationship between secretory otitis media (SOM) and injury of tensor veli palatini (TVP) muscle injury after radiotherapy, then to explore the pathogenesis of SOM in patients with nasopharyngeal carcinoma (NPC) after radiotherapy. METHOD: The cross section area (CSA) of TVP and medial pterygoid (MP) muscle were measured in MRI of 32 patients with NPC before and after radiotherapy, meanwhile the incidence of SOM were surveyed after radiotherapy, then to analyze the relationship between the change of TVP and the incidence of SOM after radiotherapy. RESULT: Of 48 ears without SOM before radiotherapy, 27 ears developed post-irradiation SOM, including 24 ears with TVP atrophy and 3 ears without TVP atrophy, and 21 ears had no post-irradiation SOM, including 8 ears with TVP atrophy and 13 ears without TVP atrophy. chi2 test showed significant difference (P < 0.01). It indicated that post-irradiation SOM have correlation with TVP atrophy. The more possibility of TVP atrophy occurred after long time radiotherapy. CONCLUSION The atrophy of TVP in patients with NPC usually occurs 6 months after radiotherapy, and this may result in the post-irradiation SOM. The pathogenesis of post-irradiation SOM need further study functionally.

OBJECTIVE: To propose the concept of rhinogenic otitis media and explore its pathomechanism through analyzing the diagnosis and treatment on secretory otitis media caused by unhealthy nasal cavity structure. METHOD: Conservative treatment and correlative operation under nasoscope were undertaken in 176 otitis media patients with unhealthy nasal cavity structure. RESULT: Of 176 cases, 156 cases recovered completely (88.64%), 18 cases got effective treatment (10.23%), and 2 cases got ineffective treatment (1.14%). CONCLUSION One important cause of the secretory otitis media is unhealthy nasal cavity structure, so correcting the unhealthy nasal cavity structure is the main ways to treat rhinogenic otitis media.
