OBJECTIVETo discuss the treatment characteristics of secretory otitis media (SOM) in cleft palate children.

METHODSA total of 319 patients (524 ears) with SOM and cleft palate (3-14 years old) who accepted treatment were divided into experiment group A, group B, and group C according to effusion characteristics in the middle ear and tympanic pressure. Group A included 112 patients with serous effusion (198 ears). Group B included 162 patients with mucinous effusion (248 ears). Group C included 45 patients (78 ears) with negative pressure in the middle ear without effusion and an acoustic immittance. A total of 208 patients (246 ears) with SOM and tonsil and adenoid hypertrophy were divided into control group Al, group B1, and group Cl matched with the same effusion characteristics in the middle ear and tympanic pressure. Group A and Al accepted puncture in the tympanic cavity, group B and B1 accepted tympanostomy tubes, and group C and Cl accepted puncture in the tympanic cavity after palatoplasty, adenoidectomy, and tonsillectomy. All groups were treated with antibiotics and ear drops. Cure rate and recurrence rate between the experiment group and the control group were compared.

RESULTSThe control group had a better cure rate [93.09% (229/246)] than the experiment group [77.29% (405/524)] 12 months after treatment. The experiment group had a higher recurrence rate [14.57% (59/405)] than the control group [3.93% (9/229)]. Statistical differences were observed between the two groups (P<0.05). SOM with cleft palate initially had a low cure rate, and thus it was treated repeatedly for many times.

CONCLUSIONSOM with cleft palate is different from normal otitis media in terms of clinical manifestation, treatment, outcome, and prognosis. This case should be considered a special otitis media to be treated with special examination and therapy to obtain better results. Repeated puncture in the tympanic cavity and tympanostomy tubes for six months according to effusion characteristics are better treatment options for patients with SOM and cleft palate.

Based on the characteristics of clinical symptoms of secretory otitis media in traditional Chinese and Western medicine,by reference to clinical diagnostic criteria,efforts were made to analyze and establish the Western medical diagnostic criteria and traditional Chinese medicine( TCM) syndrome differentiation criteria for secretory otitis media,and summarize the modeling methods and model characteristics of secretory otitis media animal models. According to the clinical diagnostic criteria and symptom characteristics,the coincidence degree between the existing animal models and clinical symptoms was evaluated,and its advantages and disadvantages were defined. On the basis of the statistical results,there were fewer methods for modeling secretory otitis media animal models,and only a specific relevant pathogenic mechanism could be revealed. Among them,the model with a higher coincidence degree was genetic engineering technology modeling and injection into the middle ear vesicles. The two modeling methods of bacterial factors highly coincided with the clinical symptoms of Western medicine,but both failed to reflect the TCM syndrome type. Therefore,establishing an animal model that simultaneously reflects the characteristics of clinical symptoms of secretory otitis media in traditional Chinese and Western medicine,and improving the evaluation criteria of secretory otitis media based on animal models are the main tasks of future studies on secretory otitis media.

OBJECTIVE: To investigate the curative effect of corticosteroid on acute otitis media (AOM) with middle ear effusion. METHOD: Forty-three children (43 ears) with AOM and abnormal tympanogram were enrolled in a prospective, randomized trial. Twenty-three cases (23 ears) were treated with Dexamethasone and Cefuroxime Sodium, while the other 20 cases (20 ears) were only treated with Cefuroxime Sodium. RESULT: The period of normalization of tympanometric findings in Dexamethasone treatment group was (54.6+/-6.2) days, which was much longer than that in the group without Dexamethasone treatment (38.5+/-6.1). Three months after treatment, the curative rate of Dexamethasone treatment group was higher than that of the group without Dexamethasone treatment. CONCLUSION Corticosteroid can obviously improve middle ear effusion and shorten the duration of middle ear effusion of AOM in the first 2 weeks. To some extent, corticosteroid can also improve middle ear effusion in long term. It indicates that corticosteroid be used as an effective adjunctive drug in treating AOM with middle ear effusion.

Objective: To study the effect of the inhibitor of Notch signaling pathway-γ-secretase inhibitor DAPT on the ultrastructures of middle ear in the ovalbumin (OVA)-mediated allergic OME in vivo. Methods: Male Sprague-Dawley (SD) rats, weighing 250-300 g, were completely and randomly divided into three groups (5 rats, 10 ears in each group):(1)Control group(2)OME group(3)OME+DAPT group. Rats in the OME group underwent systemic and local sensitization by intraperitoneal and intratympanic injection of ovalbumin to make the model of OVA-induced OME. Rats in the control group were sensitized with PBS. On the basis of establishing the OME model, OME+DAPT group were intraperitoneal injected with DAPT (10 mg/kg) for seven consecutive days and were administered before intratympanic injection of ovalbumin. After the model was successfully established, endoscopy,H&E staining and scanning electron microscopy were used to study the histology and mucous-ciliary ultrastructures of the non-ciliated and ciliated mucosa in the middle ear of each group. One-way ANOVA and Tukey methods were used for statistical analysis. Results: H&E staining showed that the three groups had statistically significant differences in submucosal thickness both in non-ciliated and ciliated regions (non-ciliated area:(6.83±1.47)μm, (38.58±9.57)μm, (32.17±11.89)μm, respectively. F=107.9;cilia area:(26.69±3.22)μm, (30.41±6.75)μm, (26.76±4.06)μm, respectively. F=5.62,both P<0.01). The thickness of the submucosa in the non-ciliated area and the cilia area of the OME group were significantly thicker than that of control group (F=42.08 and 4.40,both P<0.05); the thickness of the non-ciliated area and the ciliated area in OME+DAPT group were reduced compared to OME group(F=1.55 and 2.77,both P<0.05). Scanning electron microscopy showed that the array of cilia on the middle ear mucosa was disorderly arranged and inversed, this phenomenon was relieved in the OME+DAPT group. The number of goblet cells in the control group, OME group, and OME+DAPT group were 9.87±1.92; 15.67±5.77; 10.33±1.99 respectively and the difference between them was statistically significant (F=11.43, P<0.01). The number of goblet cells in the OME group were significantly higher than those in the control group (F=9.00,P<0.01) and the number of goblet cells in the OME+DAPT group were decreased compared to those of OME group (F=8.41, P<0.01). Conclusions: The study demonstrates the pathological changes of the ultrastructure in middle ear in OVA-induced OME and the effect of the γ-secretase inhibitor on it. In OME group, the cilia are disorderly arranged and inversed, the number of goblet cell is increased and they are swelled which suggest the hypersecretion of the mucus. DAPT can regulate OVA-induced allergic inflammation and relieve pathological changes of ultrastructure in middle ear mucociliary transport system through alleviating submucosal inflammation, reducing the hypersecretion of goblet cell and the morphological damage of cilia through the Notch signaling pathway.

BACKGROUND AND OBJECTIVE: Hunter syndrome(mucopolysaccharidosis (MPS) type II) is a genetic, metabolic disease of excessive mucopolysaccharide storage leading to mental and skeletal abnormalities, distinctive facial features, hearing loss, and airway problems. Its eventual lethal outcome results from cardiac failure and progressive obstruction of the airway. We tried to outline the otolaryngologic manifestations and management of patients based on the results of our study and review of the relevant literature. MATERIALS AND METHODS: Nine patients with Hunter syndrome were included in this study. Every patient was interviewed for the evaluation of any abnormality in the head and neck region, intelligence and language. Audio tests, temporal bone CT, and plain films of cervical spine were also performed. RESULTS: Upper airway obstruction occurred in most of patients, and necessitated tonsillectomy and adenoidectomy in 4 patients. Tracheal narrowing occurred in 3 patients. Otitis media with effusion, hearing loss and thickening of the external auditory canal and tympanic membrane were commonly observed in patients, and ventilation tubes were inserted in 4 patients. Mental retardation was more profound in the severe type Hunter syndrome, but speech function was disordered in both severe and mild type. CONCLUSION: Accurate evaluation and management of airway obstruction is needed to prevent lethal airway problems. Aggressive audio and otological managements, including the management of otitis media, hearing aids and speech therapy are required to enhance communicative development and improve their quality of life.
