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 investigate the occurrence and managements of poor recovery after total endoscopic middle ear surgery. Methods:A total of 302 cases（315 ears） who underwent endoscopic middle ear surgery in our hospital from June 2020 to June 2021 were collected. Follow up by means of endoscopy, pure tone hearing threshold, tympanogram was conducted at 1 month, 3 months, 6 months and 1 year after surgery to analyze the incidence, possible causes, treatment strategies and effects of poor results tympanic membrane healing and hearing recovery. Results:Among 302 patients（315 ears） followed up, there were 28 cases with poor recovery. There were fourteen cases of poor eardrum healing, of which 10 cases achieved healing of eardrum after tympanic membrane patching in the outpatient department, with a success rate of about 71.4%. TM recurrence adhesion occurred in 4 cases after surgeries of cholesteatoma and adhesive otitis media. One case completely recovered after self eustachian tube insufflation, while 2 cases maintained the degree of eardrum subsidence, and one ineffective patient chose resurgical treatment, with an effective rate was 75.0%. Failure in hearing improvement occurred in 8 cases, all of which underwent second surgical exploration, and seven cases were improved after the second surgery, with an effective rate of 87.5%. Among the 8 patients with no improvement or aggravation of hearing loss after surgery, four cases had postoperative B-type or C-type of tympanogram, and the hearing could not improve after self eustachian tube insufflation for secondary surgical exploration. and the hearing improved after the secondary surgery. Incorrect orientation of ossicular prosthesis was accounted for another 2 cases, the hearing was improved after the ossicular orientation adjustment. One patient with lateral healing of TM and failed hearing recovery was corrected by a second operation. One case of tympanosclerosis underwent stapes release surgery, but hearing recovery still failed. One patient had recurrent postoperative cicatricial atresia of external auditory canal, and the patient was reluctant to undergo reoperation. Postoperative delayed facial paralysis occurred in 1 case, and the facial paralysis recovered recovered after conservative treatments. Conclusion:Eardrum patch and eustachian tube autoflation are simple and effective early outpatient treatment for patient with poor recovery. For those who failed with conservative treatments such as eardrum patch or eustachian tube and poor hearing recovery, the second surgical exploration is safe and effective. Regular follow up after endoscopic middle ear surgery is necessary for the managements of poor recovery.

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 explore the clinical characteristics and treatment methods of middle ear cholesteatoma with intracranial and extracranial complications as the first diagnosis. Methods:A total of 244 patients were initially diagnosed with intracranial and/or extracranial complications associated with middle ear cholesteatoma at the First Affiliated Hospital of Zhengzhou University from January 2015 to January 2022, and medical records were collected and retrospectively analyzed. Results:Among 244 patients with intracranial and extracranial complications of middle ear cholesteatoma, 203 cases had one complication, 34 cases had 2 complications, and 7 cases had 3 or more complications. One hundred and eighty-six cases presented labyrinthitis, 41 cases had peripheral facial paralysis, 27 cases had periauricular abscess, 12 cases had meningitis, 10 cases had brain abscess, 7 cases had sigmoid sinus lesions, 6 cases had epidural abscess, and 4 cases demonstrated hydrocephalus. Conclusion:The destructive nature of middle ear cholesteatoma can lead to intracranial and extracranial complications. The incidence rate of extracranial complications is highest for labyrinthitis. Patients with otitis media who complained dizziness should raise clinical suspicion for potential labyrinthitis. The second most prevalent extracranial complication is peripheral facial paralysis, and early facial nerve decompression surgery is critical for better recovery of facial paralysis symptoms. Brain abscess is the most common intracranial complications, which has the highest fatality rate. Clinicians should be alert to otogenic brain abscess. Otolaryngology and neurosurgery teams should cooperate and evaluate patients' middle ear lesions and brain abscess, and jointly develop personalized treatment plans.

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.

Otitis media is an infection of the middle ear mainly caused by bacteria, and current treatments rely heavily on antibiotics. However, the emergence of antibiotic-resistant bacterial strains seriously affects their efficacy. In our study, we found that extracellular vesicles (EVs) derived from human natural killer cells (NKs) inhibit the proliferation of both standard and levofloxacin (LVX)-resistant strains of Staphylococcus aureus in a dose-dependent manner. Moreover, compared to LVX, EVs were more effective at reducing effusion and rescuing hearing thresholds in animal models. For LVX-sensitive strains, EVs were significantly more effective in terms of curative time but not curative rate. For LVX-resistant strains, EVs were significantly more effective in terms of both curative rate and curative time when applied alone or applied jointly with LVX. In summary, we found that NK EVs are highly effective in treating otitis media, providing an alternative approach for treating this common disease.

Objective:To observe the position and morphology of tubular cell in lateral facial recess by CT scanning and surgical finding, and its clinical significance. Methods:Thirty patients（32 ears） with cholesteatoma and/or adhesive otitis media requiring radical mastoidectomy and tympanoplasty were included in this study. To observe the morphology of the tubular cell in the lateral facial recess cavity through temporal bone HRCT and surgery, and to analyze its relationship with the facial nerve. Results:Tubular cell were found in 59.4%（19/32） ears by temporal bone HRCT and through surgeon. The length ranged from 1.5-6.5 mm, with median length of 2.5 mm. All of them opened in the facial recess, ran on the posterior wall of the facial recess, and even reached the bottom of the inferior tympanic cavity or the level of the inferior wall of the external auditory canal（sagittal view and surgical findings）. Probing from the inside out, the tubular cell located between the second genu of the facial nerve and the chorda tympani, which was a part of the lateral wall of the facial nerve（facial crest）. When the tubular cell is occupied by granulation tissue, it is easy to be regarded as the facial nerve. Fully drilling out the tubular cell is helpful to cut down the facial nerve crest. In the study, the follow-up and/or postoperative no facial paralysis happens during the operation and in the follow up. Conclusion:Preoperative temporal bone HRCT can clearly show the tubular cell in the lateral facial recess cavity. Comprehensive and accurate identification of these structures is helpful to fully cut down the facial nerve crest and remove the hidden lesions in the posterior tympanic cavity.
