That condition where the tympanic membrane is displaced toward the promontory is termed atelectasis. Thirty-seven patients (61 ears) showing various degrees of atelectasis graded from stage 1 to stage 4 were studied. Atelectatic drums are an inflammatory phenomenon occurring in underventilated ears. This conclusion is reached by considering the reversibility of the atelectasis upon ventilation; while the inflammatory factor can be deduced from the history and histopathology of the atelectatic drum, as well as the histology of the necrosed incus, the latter occurs in over a third of our cases. Also pneumatization of the mastoid is almost never present. Twelve (21%) of the ears treated did indeed develop a perforation at one time or another (two had cholesteatomas). Chronic granulating external otitis with specific features occurred in 15% of cases. The characteristics of these ears and their case histories lead us to view atelectatic ears as part of the otitis media syndrome, where their place is somehow transitional between secretory otitis media on the one hand and chronic otitis media on the other.

Intact Tympanic Membrane

Primary ectopic meningioma of the middle ear is relatively rare in clinical practice. It is often difficult to distinguish it from chronic otitis media or otitis media with effusion due to its similar and atypical clinical symptoms. We report a case of epithelial tympanic ectopic meningioma with the main complaints of otalgia, aural fullness, and hearing loss. It was accidentally discovered during tympanotomy due to the symptoms of recurring refractory secretory otitis media. This article briefly reviews the relevant literature in recent years, summarizes the characteristics of primary ectopic tympanic meningioma with intact tympanic membrane, and emphasizes the diagnosis and treatment strategy of the middle ear mass.

Abstract Extraction of causal relations between biomedical entities in the form of Biological Expression Language (BEL) poses a new challenge to the community of biomedical text mining due to the complexity of BEL statements. We propose a simplified form of BEL statements [Simplified Biological Expression Language (SBEL)] to facilitate BEL extraction and employ BERT (Bidirectional Encoder Representation from Transformers) to improve the performance of causal relation extraction (RE). On the one hand, BEL statement extraction is transformed into the extraction of an intermediate form—SBEL statement, which is then further decomposed into two subtasks: entity RE and entity function detection. On the other hand, we use a powerful pretrained BERT model to both extract entity relations and detect entity functions, aiming to improve the performance of two subtasks. Entity relations and functions are then combined into SBEL statements and finally merged into BEL statements. Experimental results on the BioCreative-V Track 4 corpus demonstrate that our method achieves the state-of-the-art performance in BEL statement extraction with F1 scores of 54.8% in Stage 2 evaluation and of 30.1% in Stage 1 evaluation, respectively.

The Relationship

The Vanhuyse, Creten, and Van Camp (1975) model for analyzing high frequency tympanograms predicts the shapes of conductance, susceptance, and admittance tympanograms from the relationship between resistance and reactance tympanograms at the tympanic membrane. This model has been applied primarily to low impedance middle-ear pathologies but has not been applied extensively to the more commonly occurring high impedance pathologies. The purpose of this study was to extend the Vanhuyse et al. (1975) model to high impedance pathologies and to identify tympanometric parameters associated with otosclerosis, secretory otitis media, and lateral ossicular fixation. Data from previous experiments on the shape and absolute values of resistance and reactance tympanograms were used to calculate 678-Hz admittance tympanograms that were unique to each of the three high impedance pathologies. Guidelines for differentiating among the middle-ear pathologies on the basis of high frequency tympanometric shapes are presented.

<p class="abstract"><strong><span lang="EN-US">Background:</span></strong>Secretory Otitis Media (SOM) is a common otological condition in children presenting most commonly with hearing loss. If untreated for long time, it can affect the language development of child. Its causes are multifactorial and treatment depends on the etiology. Various treatment modalities (medical and surgical) are available and they are administered in isolation or in combination. The objectives of the study were the present study was conducted with the objectives of knowing the most common age group affected by SOM, the common etiological factors of SOM and the outcome of various modalities of treatment of SOM.</p><p class="abstract"><strong><span lang="EN-US">Methods:</span></strong>This prospective study was conducted at a tertiary care teaching hospital of North Gujarat. IEC approval and consent from the patients were taken. 40 patients diagnosed with SOM were included in the study and their clinical and demographic details and treatment outcomes were studied.  </p><p class="abstract"><strong><span lang="EN-US">Results:</span></strong>Of the 40 patients, 65% were males. SOM was common in young children. Most of the cases (55%) were below 10 years of age. In 80% of cases SOM was bilateral. Deafness was the most common symptom (95%) with which patients presented with, followed by URTI and pain. All patients had impaired tympanic membrane mobility. Retraction of tympanic membrane was the next common otoscopic finding (85%). Initial management was medical and 18 patients required surgical intervention.</p><p class="abstract"><strong><span lang="EN-US">Conclusions:</span></strong>SOM is a common ear disorder in children. Initial medical treatment has a definitive role and should be tried in all cases before surgical intervention is contemplated. A variety of surgical procedures are available which can be used depending on the indication. Complete recovery is expected to occur in most of the cases by a period of 3-6 months.</p>

Otorrhea is the most frequent complication of the use of tympanostomy tubes. When it occurs after the immediate postoperative period, otorrhea is probably the result of external contamination of the middle ear or acute otitis media. We analyzed data from 627 operations upon 1248 ears of 491 children with chronic secretory otitis media and found that delayed onset (longer than 7 weeks) postoperative otorrhea occurred after 26.4 percent of the 382 operations in which tympanostomy tubes were used. The average number of episodes of otorrhea per case was 1.46 and ranged from 1 to 9. The rate of otorrhea occurrence in patients with tubes in place was significantly higher in the summer months. Otorrhea also occurred after 9.0 percent of 245 myringotomy procedures. The average number of episodes was 1.32 and ranged from 1 to 3. Treatment of postoperative otorrhea increases the health care costs of surgical treatment of chronic otitis media with effusion; this problem should be included in the calculation of cost-effectiveness.
