Introduction: Subacute thyroiditis (SAT) and acute suppurative thyroiditis (AST) are two distinct inflammatory conditions but share many overlapping clinical and biochemical features, which may pose a diagnostic challenge. We report a case of SAT mimicking AST. Case: A 39-year-old female presented with a 3-week history of painful neck swelling and symptoms of thyrotoxicosis, including palpitations, heat intolerance, and diaphoresis. She had no family history of thyroid disease. On examination, she was febrile and had a smooth and tender goiter. Her blood tests showed leukocytosis with elevated erythrocyte sedimentation rate and C-reactive protein. Her thyroid function test (TFT) showed thyroid-stimulating hormone of 0.023 mIU/L and free thyroxine 4 of 32.15 pmol/L. An urgent ultrasound revealed a large, ill-defined heterogeneously hypoechoic lesion predominantly at the left lobe of the thyroid gland with mild intralesional vascularity. These were reported as features of thyroiditis with infective or early suppurative changes. Fine needle aspiration (FNA) of the lesion was attempted by the radiologist but was unsuccessful. She was treated with intravenous antibiotics and nonsteroidal anti-inflammatory drugs (NSAIDs), but symptoms persisted. Repeated ultrasound and computed tomography scans about 1 week later confirmed an enlarged thyroid gland with no obvious lesion or collection within the gland. The diagnosis was revised to SAT, and prednisolone 15 mg OD was started. This resulted in rapid improvement in her symptoms and inflammatory markers. Four weeks later, she remained asymptomatic, and prednisolone was gradually tapered off. Serial TFT monitoring showed a classic triphasic pattern with an initial hyperthyroid phase, followed by hypothyroidism before returning to euthyroidism. Conclusion SAT can present with a focal lesion on the ultrasound during the early stage of the disease, making it difficult to distinguish from a thyroid abscess due to overlapping features. Good clinical judgement guided by FNA and appropriate follow-up imaging may be helpful in differentiating between the two conditions.

Objective:The objective of this study is to analyze the detection rate, the pathogenic fungus distribution, risk factors and drug sensitivity of fungal infection of external auditory canal in patients diagnosed with chronic otitis media. Methods:The data of a total of 419 patients with chronic suppurative otitis media or middle ear cholesteatoma who were admitted from January 2019 to February 2023 were retrospectively analyzed. Results:A total of 419 patients were included, and 71 patients（16.9%） were positive for fungal culture. The disease mostly occurred in subjects aged 51-60 years old, and patients over 60 years old（47 cases, 66.2%）. From the fungal culture of external auditory canal secretions, 48 cases（11.4%） of Aspergillus and 14 cases（3.3%） of Candida were identified. The prevalence of fungal cultures in patients with chronic suppurative otitis media（20.8%） was significantly higher than that in patients with middle ear cholectestoma（4.9%）. The detection rate of Fungal was significantly increased after topical treatment with antibiotic ear drops（47.0% vs 13.6%）. Most of the isolated fungal strains are wild-type, and they are the sensitivity to voriconazole and fluconazole was the highest（97.2%）. For patients with positive fungal culture, iodoform gauze with triamcinolone acetonide and econazole cream was used to fill the external auditory canal during surgery. There was no significant difference in the tympanic membrane healing rate between patients with positive fungal culture and patients with negative fungal culture at 3 weeks after surgery（98.6% vs 97.7%）. Conclusion:Fungal infections of external auditory canal in patients with chronic otitis media tend to occur in older patients, which is more common in patients with chronic suppurative otitis media. Long-term topical treatment with antibiotic ear drops is an independent risk factor for fungal infection of external auditory canal in patients with chronic otitis media. The isolated fungal strains were highly sensitive to antifungal drugs. Therefore, it is advisable to refrain from employing topical antibiotic treatment for elderly patients with chronic suppurative otitis media/middle ear cholesteatoma, abuse of local antibiotic therapy should be avoided, and Fungal-related pathogenic examinations should be actively performed and anti-fungal drugs should be added if necessary.

Objective:To compare the differences in postoperative healing rates, hearing improvement, and complication rates between endoscopic butterfly inlay cartilage tympanoplasty and underlay cartilage tympanoplasty in Small-to-Medium-Sized Tympanic Membrane Perforations, and to provide clinical basis for indication of the butterfly inlay cartilage tympanoplasty. Methods:This study enrolled patients with chronic suppurative otitis media or traumatic tympanic membrane perforations who were treated at the Department of Otorhinolaryngology Head and Neck Surgery, the First Affiliated Hospital of Chongqing Medical University, between January 2022 and May 2023. Inclusion criteria comprised a dry ear period exceeding 3 months, absence of middle ear or mastoid pathology confirmed by temporal bone CT, and an air-bone gap of less than 40 dB. All surgeries were performed by the same surgeon using tympanoplasty techniques. Based on the surgical approach and perforation size, patients were categorized into four groups: Group A（butterfly cartilage tympanoplasty, perforation ≤3 mm）: 23 cases. Group B（butterfly cartilage tympanoplasty, perforation 3-5 mm）: 17 cases. Group C（full-thickness cartilage underlay tympanoplasty, perforation ≤3 mm）: 12 cases. Group D（full-thickness cartilage underlay tympanoplasty, perforation 3-5 mm）: 22 cases. Data collected included perforation duration, preoperative Eustachian Tube Score（ETS）, pure-tone audiometry, otoscopic findings, and postoperative follow-up data on pure-tone thresholds, otoscopic outcomes, and complications such as graft infection and otorrhea. Results: The mean postoperative follow-up period was 4 months （range: 3-12 months）. A total of 74 patients were enrolled, including 40 undergoing butterfly cartilage tympanoplasty and 34 receiving full-thickness cartilage inlay tympanoplasty. In the <3 mm perforation subgroup, the patients receiving butterfly technique （23 cases） exhibited a postoperative air-bone gap （ABG） improvement of （2.33±8.21） dB, and those receiving the inlay technique （12 cases） showed an ABG improvement of （2.49±7.9） dB, with no statistically significant difference between the two groups （P>0.05）. In the 3-5 mm perforation subgroup, the patients receiving butterfly technique （17 cases） demonstrated an ABG improvement of （8.16±5.69） dB, and those receiving the inlay technique （22 cases） achieved an ABG improvement of （8.08±10.42） dB, which were not significantly different （P>0.05）. Tympanic membrane healing rates across the four subgroups were 95.65%, 94.12%, 100%, and 95.45%, respectively, with no statistically significant differences （P>0.05）. Conclusion:In patients with tympanic membrane perforations ≤3 mm and 3-5 mm, butterfly cartilage tympanoplasty achieves comparable audiological outcomes to full-thickness cartilage underlay tympanoplasty. Compared with the underlay technique, the butterfly method is less invasive, preserves the normal anatomical structure of the tympanic membrane, requires a shorter dry ear period, and yields higher patient satisfaction. Therefore, it can be safely recommended for perforations ≤5 mm that do not require tympanotomy exploration.

Objective:To investigate the distribution of pathogenic bacteria in the ear canal secretions of patients with chronic suppurative otitis media（CSOM）, the changes in the levels of interleukin-8（IL-8） and Toll like receptor 4（TLR4） in the ear canal secretions, and their clinical significance. Methods:This study selected 128 CSOM patients who visited our hospital from January 2022 to February 2024 as the study subjects and recorded them as the CSOM group. Additionally, 135 volunteers who underwent physical examinations at our hospital during the same period were regarded as the control group. Video otoscopy was used to collect and cultivate ear canal secretions, and a fully automated microbial identification instrument was used to identify the bacterial species. ELISA was applied to detect levels of IL-8, TLR4. Multivariate logistic regression was employed to examine the factors that affect the occurrence of CSOM. Pearson correlation was applied to analyze the correlation between IL-8, TLR4 levels and various influencing factors. ROC curve was applied to analyze the diagnostic value of IL-8 and TLR4 levels for the occurrence of CSOM. Z-test was applied to compare the differences in AUC. Results:Among 128 patients, the detection rate was 89.06%, and a total of 181 strains of pathogenic bacteria were cultured, among them, Gram positive bacteria accounted for the highest proportion of 54.14%, followed by Gram negative bacteria, accounting for 34.25%, and finally fungi, accounting for 11.60%. The common bacteria were Staphylococcus aureus （20.44%）, Pseudomonas aeruginosa （13.26%）, and Staphylococcus epidermidis （8.29%）. The resistance of Gram-positive bacteria to penicillin, clindamycin, erythromycin, and amoxicillin is high. Gram-negative bacteria are highly resistant to penicillin, ampicillin and erythromycin. Fungi are resistant to ketoconazole and fluconazole. The levels of IL-8 and TLR4 in CSOM group were higher than those in the control group, and gradually increased with the increase of hearing impairment. （P<0.05）. Elevated levels of IL-8, TLR4 were independent risk factors for the occurrence of CSOM（P<0.05）. The AUC of CSOM diagnosed by IL-8 and TLR4 alone was 0.790 and 0.777, respectively, while the AUC of combined diagnosis was 0.898, which was better than their respective individual diagnoses（both P<0.05）. Conclusion:The distribution of pathogenic bacteria in the ear canal secretions of CSOM patients is mainly Gram positive, with common ones being Staphylococcus aureus and Pseudomonas aeruginosa. The levels of IL-8 and TLR4 in CSOM patients are higher than those in the control group. The higher the levels, the higher the degree of hearing loss, which can be used for clinical diagnosis.

Objectives: To determine the initial clinical diagnoses of patients with tuberculous otitis media (TBOM), to determine the value of PCR test, biopsy, and ancillary diagnostic procedures in detecting middle ear TB infection, and to establish the differences in treatment outcomes. Methods: The clinical records of twenty-eight patients identified with middle ear TB infection by PCR test and biopsy, from January 2010 to December 2016, were reviewed to determine their initial clinical diagnoses. The positivity rates of PCR test and biopsy were compared. The records of 12 patients included in a previous publication were revisited and included in the present study population. The combined cases were classified according to clinical diagnosis to constitute a summary of demographic characteristics, clinical diagnoses, laboratory tests, and treatment outcomes. Results of diagnostic and surgical procedures were reviewed and analyzed. Clinical findings and hearing test results before and after treatment were compared. Results: Of the 28 patients, eight different clinical diagnoses of patients confirmed with middle ear TB were determined. PCR test diagnosed most cases belonging to the early and chronic stages of the disease process. Biopsy diagnosed mostly the chronic cases but failed to diagnose acute cases and late cases with diagnosis of chronic suppurative otitis media with cholesteatoma. By including the twelve cases that were published in 2011, the range of clinical diagnoses was expanded and an outcome of eleven clinical diagnoses confirmed with TB infection was established. Analysis of treatment outcomes showed that the clinical and hearing outcomes were better for patients managed at the early stage of the disease than for those presenting at the late stages of the disease process who underwent more complicated surgical procedures. Conclusion Our study supports the concept of tuberculous otitis media (TBOM) clinical spectrum, implying a paradigm shift in the established thinking that TBOM presents only as a chronic disease. The combined use of PCR and biopsy is a potential diagnostic tool to improve case detection rate, further broaden the scope of the clinical spectrum, and develop better control and preventive strategies for TBOM.

Mouret abscess is a rare extracranial complication of suppurative otitis media. It is generally believed to be a deep neck abscess caused by inflammation leading to the rupture of the bony tip of the mastoid tip. The location of Mouret abscess is deep. The symptoms are insidious at the onset, but may eventually spread to the surrounding tissue, and even lead to mediastinal abscess, cavernous sinus thrombosis, meningitis, dyspnea and other serious complications. At present, with the popularization of antibiotics, the occurrence rate of Mouret abscess is very low, and only sporadic cases have been reported.In this paper, a case of Mouret abscess caused by cholesteatoma was analyzed to explore Mouret abscess in terms of the route of infection, clinical manifestations, imaging features, diagnosis and treatment.
