Objective:To investigate the clinical features, imaging characteristics, surgical strategies, and therapeutic outcomes of otitis media complicated with inflammatory response of local meninges.Methods:A retrospective analysis was conducted on the clinical data of 8 patients with chronic suppurative otitis media complicated with inflammatory response of local meninges, treated by the Department of Otolaryngology, Head and Neck Surgery, PLA General Hospital from 2019 to 2023. Appropriate surgical strategies were selected based on the patient′s clinical manifestations, imaging characteristics, extent of lesions, and facial nerve function. Follow-up was performed postoperatively to assess the therapeutic outcomes.Results:Among the eight patients, there were six males and two females, with an average age of (55.9±12.6) years old. The primary clinical manifestations included otorrhea, hearing loss, facial paralysis, earache, headache, and fever. All patients had a history of chronic suppurative otitis media and tympanic membrane perforation, with varying degrees and types of hearing loss. Seven patients presented with peripheral facial palsy preoperatively, with the House-Brackmann (H-B) grading scale as follows: 4 cases (4/7) in grade Ⅳ, 1 case (1/7) in grade Ⅴ, and 2 cases (2/7) in grade Ⅵ. The mean duration of otorrhea and/or hearing loss was (24.68±12.18) years, while, the average duration of severe headache, aggravated otorrhea and facial paralysis was (2.73±3.92) months. Preoperative high-resolution CT scan of the temporal bone revealed soft tissue shadow in the middle ear and mastoid process, with partial defects in the mastoid cortex. Cranial MRI T1WI showed high signal in the meninges on the affected side, with contrast-enhanced MRI indicating localized meningeal thickening. Four patients (4/8) had diabetes mellitus, and 2 patients (2/8) had a history of middle ear/mastoid surgery. All patients underwent surgical treatment, including thorough removal of lesions, adequate drainage, and facial nerve decompression. Tympanoplasty and hearing reconstruction were performed when conditions permitted. Specifically, 5 patients underwent intact canal wall radical mastoidectomy with facial nerve decompression and tympanoplasty, 2 patients underwent canal wall down mastoidectomy with facial nerve exploration decompression, and 1 patient underwent modified radical mastoidectomy. Postoperatively, patients experienced significant relief and gradual disappearance of ear and head pain. The postoperative H-B grading scale of facial nerve function was as follows: 4 cases in grade Ⅰ (4/8, including 1 case without preoperatively facial palsy), 2 cases (2/8) in grade Ⅱ, and 2 cases (2/8) in grade Ⅲ. Postoperative cranial MRI showed a significant reduction in localized meningeal thickening on the affected side.Conclusions:Patients with long-term chronic suppurative otitis media and/or cholesteatoma who suddenly presented with headache, fever, aggravated otorrhea, and facial paralysis should be suspected of having inflammatory response of local meninges. High-resolution CT of temporal bone and cranial MRI provide crucial diagnostic information. Early surgical exploration and thorough lesion removal are effective treatment methods.

Objective:To explore the perioperative precautions, rehabilitation effect, and affecting factors in cochlear implantation (CI) among patients with hereditary syndromic hearing loss.Methods:This was a retrospective cohort study. 47 patients diagnosed as hereditary syndromic deafness were treated in the Department of Otolaryngology-Head and Neck Surgery of the Chinese PLA General Hospital from 2010 to 2021, including 26 males and 21 females, aged 0.9-25 years. All patients received unilateral or bilateral CI. Clinical manifestation combined with genetic testing was used to diagnose syndromic hearing loss. The risks and precautions of CI in these patients were summarized from preoperative imaging, intraoperative observations, and postoperative complications. Single factor linear regression and multiple linear regression models in SPSS 26.0 software were used to evaluate the effects of various factors on auditory and speech rehabilitation after CI for syndromic hearing loss. The postoperative outcomes were analyzed through aided hearing thresholds, categories of auditory performance (CAP) scale, and speech intelligibility rate (SIR) scale.Results:Thirteen kinds of syndromes, totally 47 cases, including CHARGE (20 cases), Waardenburg (9 cases), Autosomal dominant deafness-onychodystrophy (DDOD, 4 cases), Pendred (3 cases), Noonan Syndrome with Multiple Lentigines (NSML, 2 cases), Branchio-Oto-Renal (BOR, 2 cases), Bart-Pumphery (1 case), Perrault (1 case), Kabuki (1 case), Frontometaphyseal dysplasia type 2 (FMD 2, 1 case), Mandibulofacial dysostosis Guion-Almeida type (MFDGA, 1 case), Coffin-Siris (1 case), and 10q26.12-q26.3 del (1 case), were enrolled. The perioperative special management included the following measures. For patients with cardiac and/or cartilage development issues, preoperative assessments of cardiac function and/or laryngeal cartilage development were performed to minimize anesthetic risks. For patients with mild intellectual disability and/or an auditory neuropathy phenotype, preoperative communication with the patients′ families was conducted to explain the limitations of CI and assist in setting reasonable expectations. For syndromic hearing loss patients who commonly present with inner ear malformations, facial nerve anomalies, and/or intraoperative cerebrospinal fluid leakage, appropriate electrodes were selected prior to surgery, intraoperative facial nerve monitoring and careful cerebrospinal fluid leak repair were conducted, respectively. For patients with NSML accompanied by coagulation issues, the postoperative compression bandaging duration was extended to reduce the risk of hematoma formation. The daily duration of cochlear implant use, the presence of cochlear malformation, and developmental delay were independent factors influencing postoperative CAP scores. The daily duration of cochlear implant use, developmental delay, and unilateral or bilateral CI were independent factors influencing postoperative SIR scores.Conclusions:Hereditary syndrome deafness is a rare disease that affects multiple organs and causes extensive functional impairment. Before CI, a comprehensive evaluation of major affected organ functions is required to assess anesthetic and surgical risks. Genetic diagnosis not only identifies the molecular etiology of patients with syndromic hearing loss and reveals rare phenotypes, but also aids in prognostic evaluation. The main factors affecting CI outcomes in patients with syndromic hearing loss include the presence of cochlear malformations, developmental delays, daily duration of cochlear implant use, and bilateral implantation status.

Objective:To investigate the role of a modified positioning device in improving image quality and diagnostic efficacy for thyroid cancer in contrast-enhanced neck CT imaging.Methods:This prospective cross-sectional study included 137 patients with pathologically confirmed thyroid lesions who underwent contrast-enhanced neck CT at Zhangzhou Affiliated Hospital of Fujian Medical University from January to April 2024. Patients scanned in January and February (modified positioning group, n=62) underwent scanning using the modified positioning device, whereas those scanned in March and April (traditional positioning group, n=75) underwent scanning with conventional positioning. The estimated volume CT dose index (CTDI vol) in the thyroid region was recorded. Subjective image quality for thyroid and neck regions was evaluated using a 5-point Likert scale. Diagnostic assessments for thyroid cancer, capsule invasion, and lymph node metastasis were independently conducted by one junior radiologist and one senior radiologist using a 5-point scoring system, with scores≥3 considered positive diagnoses. The differences of CTDI vol and image quality scores between the 2 groups were compared using Mann-Whitney U test. The diagnostic performance was evaluated by the receiver operating characteristic curve analysis. Results:The estimated CTDI vol values for the thyroid region were significantly lower in the modified positioning group compared to the traditional positioning group [11.20 (8.37, 13.56) vs. 12.46 (10.10, 19.43) mGy, Z=1.99, P=0.026]. Subjective image quality scores for thyroid and neck regions were significantly higher in the modified positioning group than in the traditional positioning group (all P<0.001). For thyroid cancer diagnosis by the senior radiologist, the modified positioning group had a significantly higher area under the curve (AUC) of 0.842 (95% CI 0.728-0.956) compared to the traditional positioning group (AUC=0.666,95% CI 0.554-0.777, Z=2.17, P=0.031). No significant differences were observed in diagnostic performance between the junior and senior radiologists for thyroid cancer, capsule invasion, and lymph node metastasis in other subgroup comparisons (all P>0.05). Conclusion:The modified positioning device using in contrast-enhanced neck CT imaging can improve image quality and diagnostic efficacy for thyroid cancer while reducing radiation exposure to the thyroid gland.

Objective:To develop a vasectomy intention scale (VIS) and evaluate its reliability and validity for assessing men's intentions toward vasectomy.Methods:Based on the Theory of Planned Behavior, the VIS was developed through a process that included literature review, panel discussions, expert consultations, and a pilot survey. A total of 264 men seeking vasectomy consultation at the Andrology Center, Department of Urology, the Third Xiangya Hospital of Central South University between December 2023 and December 2024 were recruited to assess reliability and validity of the VIS.Results:The VIS comprises 11 items across three dimensions: "background" factors, "stance and behavior" factors and "information" factors. The scale demonstrated satisfactory internal consistency (Cronbach's α=0.739). Correlations between each dimension and the total scale ("background" factors r=0.849, "stance and behavior" factors r=0.744, "information" factors r=0.440) exceeded inter-dimension correlations (ranging from 0.145 to 0.312), confirming robust construct validity. The vasectomy rates among men with different intention levels were 65.7% (92/140) in the high-intention group, 28.9% (33/114) in the moderate-intention group, and 0% (0/11) in the low-intention group, with a statistically significant difference (χ2=43.42, P<0.001). Conclusion:The VIS exhibits strong reliability and validity, serving as a validated instrument for measuring the strength of men's vasectomy intentions.
