Objective:To describe the radiologic dimensions of the Eustachian tube (pre-tympanic diameter, tubo-tympanic angle, and Eustachian tube angle) among normal ears, ears with chronic otitis media (COM) with and without cholesteatoma, in a sample of Filipino adults with COM; and to compare the dimensions of the three variables.

Methods:
Design:Retrospective Review of Records
Setting:Tertiary Government Training Hospital
Participants:The study included 69 CT scans of adults with COM, with images of 23 ears for each variable (normal ears, COM with and without cholesteatoma formation).

Results:In normal ears, the average pre-tympanic diameter was 3.976 ± 0.78 mm, the average tubo-tympanic angle was 41.529 ± 5.85 degrees, and the average Eustachian tube Angle (Reid Plane) was 27.077 ± 4.62 degrees. In patients with COM without cholesteatoma, the mean pre tympanic diameter was 4.002 ± 1.13 mm, the mean tubo-tympanic angle was 141.994 ± 6.30 degrees, and the mean measurement of the Reid plane was 24.649 ± 3.10 degrees. In ears with COM with cholesteatoma, the mean pre-tympanic diameter was 4.1993 ± 0.50mm, the mean tubo-tympanic angle was 138.789 ± 7.13 degrees, and the mean Reid plane was 26.483 ± 3.86 degrees. P-values for the pre-tympanic diameter, tubo-tympanic angle, and ET angle were .617, .198, and .098 respectively, indicating that there were no statistically significant differences in the ET dimensions of the ears with COM with cholesteatoma, without cholesteatoma and normal ears.

Conclusion:In our investigation, we found no statistically significant differences in Eustachian tube dimensions among individuals with normal ears and COM with or without cholesteatoma. This suggests that the Eustachian tube dimensions may not serve as a primary etiological factor for COM among our patients.

OBJECTIVES: Verrucous epidermal nevus (VEN), seborrheic keratosis (SK), verruca plana (VP), verruca vulgaris (VV), and nevus sebaceous (NS) are common verrucous proliferative skin diseases with similar clinical appearances, often posing diagnostic challenges. Dermoscopy and reflectance confocal microscopy (RCM) can aid in their differentiation, yet their specific features under these tools have not been systematically described. This study aims to summarize and analyze the dermoscopic and RCM features of VEN, SK, VP, VV, and NS. METHODS: A total of 121 patients with histopathologically confirmed verrucous proliferative skin diseases were enrolled. Dermoscopy and RCM imaging was used to observe and analyze the microscopic features of these conditions. RESULTS: Under dermoscopy, the 5 diseases displayed distinct characteristics: VEN typically showed gyriform structures; SK was characterized by gyriform structures, comedo-like openings, and milia-like cysts; VP and VV featured dotted vessels and frogspawn-like structures; NS presented as brownish-yellow globules. RCM revealed shared features such as hyperkeratosis and acanthosis across all 5 diseases. Specific features included gyriform structures and elongated rete ridges in VEN; pseudocysts and gyriform structures in SK; evenly distributed ring-like structures in VP; vacuolated cells and papillomatous proliferation in VV; and frogspawn-like structures in NS. CONCLUSIONS These 5 verrucous proliferative skin conditions exhibit distinguishable features under both dermoscopy and RCM. The combination of these 2 noninvasive imaging modalities holds significant clinical value for the differential diagnosis of verrucous proliferative skin diseases.

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 retrospectively analyze the clinical features and surgical efficacy of congenital cholesteatoma （CC） and acquired cholesteatoma （AC） in children. Methods:Clinical data of 169 children with middle ear cholesteatoma were reviewed in the Department of Otorhinolaryngology Head and Neck Surgery, Beijing Children's Hospital, Capital Medical University from January 2010 to July 2020. The clinical characteristics, stages, surgical methods, and postoperative recurrence rates were analyzed and summarized. Results:The age distribution of enrolled children ranged from 2 to 14 years. The mean age of the CC group was （5.60±2.48） years compared with （6.45±2.48） years in the AC group, and the difference was statistically significant （P<0.05）. Preoperative hearing in the CC group was （40.06±13.52） dB HL, which was better than in the AC group at （48.40±13.84） dB HL （P<0.05）. The proportion of stage Ⅰ in the CC group was lower than that in the AC group according to EAONO/JOS staging （P<0.05）. The recurrence rate after primary surgery was 19.23% （10/52） in the CC group compared with 36.29% （45/124） in the AC group （P<0.05）. The mastoid retention rates after all operations were 28.85% （15/52） in the CC group and 5.65% （7/124） in the AC group （P<0.05）. Conclusion:Compared with congenital cholesteatoma, acquired cholesteatoma in children is more aggressive and has more complications, higher postoperative recurrence rate, and less possibility of mastoid retention. Early clinical detection and treatment are required, and canal wall-down tympanoplasty should be considered in surgery.

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 evaluate surgical strategies and clinical outcomes in supra-labyrinthine cholesteatoma management, providing evidence-based guidance for therapeutic decision-making. Methods:Seven patients with supra-labyrinthine cholesteatoma in our hospital from 2021 to 2023 were enrolled in this study. The clinical manifestations, imaging findings, and surgical outcomes of patients were retrospectively analyzed. A systematic literature review focused on surgical anatomy correlations and imaging-based approach selection. Results:All seven cases of supra-labyrinthine cholesteatoma were unilateral. Preoperative otoendoscopy, CT, and intraoperative findings confirmed that they were classified as supral-abyrinthine cholesteatoma according to Sanna's classification. Two cases were operated entirely with otoendoscopy, three cases used a postauricular approach with microscopic assistance, and two cases involved a combined approach with endoscopy and microscopy. Hearing reconstruction with ossicular prosthesis was performed in five cases, while two cases did not undergo hearing reconstruction due to preoperative anacusis confirmed by both subjective and objective hearing tests. In all seven cases, various segments of the facial nerve were exposed during surgery, but postoperative facial nerve function remained intact, hearing was preserved, no cerebrospinal fluid leakage occurred, and no recurrences have been observed to date（as of June 2024）. Conclusion:With the advancement of imaging techniques and microsurgical technology, early diagnosis and surgical methods for supral-abyrinthine cholesteatoma have significantly improved. Compared to traditional approaches, the newer methods reduce unnecessary complications and offer advantages such as minimal surgical trauma, superior hearing preservation rates, and shorter recovery times with better postoperative neural function. This study reviews recent literature on petroclival cholesteatomas, combined with our own cases, to analyze the classification of supral-abyrinthine cholesteatoma and surgical approach selection. The findings aim to optimize treatment strategies and guide appropriate surgical methods, ultimately improving patient prognosis and quality of life.

Objective:To compare the preoperative presentation, intraoperative findings, and postoperative outcomes between middle ear cholesteatoma with tympanosclerosis （MECwTS） and middle ear cholesteatoma without tympanosclerosis （MECw/oTS）, thereby investigating the clinical characteristics of MECwTS. Methods:A retrospective analysis was conducted on the clinical data of 120 patients with middle ear cholesteatoma. Patients were divided into two groups based on the presence or absence of concomitant tympanosclerosis: the MECwTS group （n=49） and the MECw/oTS group （n=71）. All patients underwent preoperative evaluations including temporal bone CT, otoscopic examination, pure-tone audiometry, tympanometry, and assessment using the Zurich Chronic Middle Ear Inventory （ZCMEI-21） quality of life scale. All patients underwent canal wall down mastoidectomy with tympanoplasty. Concurrent ossicular chain reconstruction was performed: partial ossicular replacement prosthesis （PORP） in 83 cases and total ossicular replacement prosthesis （TORP） in 37 cases. Intraoperative disease severity was assessed using the Cholesteatoma Comprehensive Score Scale （CCSS）. Postoperative follow-up lasted at least one year and included pure-tone audiometry, otoscopic examination, and the ZCMEI-21 scale administered at ≥1 year post-surgery. Preoperative and postoperative air-bone gap （ABG） and ZCMEI-21 scores were compared between the MECwTS and MECw/oTS groups. Additionally, surgical efficacy was defined as a postoperative ABG ≤20 dB; the hearing improvement efficacy of PORP versus TORP was compared based on this criterion. Results: ①Preoperative ABG showed no significant difference between the MECw/oTS and MECwTS groups（P>0.05）. Postoperative ABG was （18.65±10.21） dB in the MECw/oTS group versus （22.55±9.53） dB in the MECwTS group, demonstrating a statistically significant intergroup difference （P<0.05）. ②Intraoperative CCSS scores were significantly higher in the MECwTS group （8.04±2.18） compared to the MECw/oTS group （5.93±1.44） （P<0.05）. ③Preoperative ZCMEI-21 scores showed no significant difference between groups （P>0.05）. Postoperative ZCMEI-21 scores were （22.24±8.11） in the MECw/oTS group versus （27.02±7.21） in the MECwTS group, indicating a statistically significant difference （P<0.05）. ④Postoperative ABG ≤20 dB was achieved in 54 patients （65.06%, 54/83） in the PORP group and 16 patients （43.24%, 16/37） in the TORP group. This difference in efficacy rates was statistically significant （P<0.05）. The overall efficacy rate for ossiculoplasty was 58.33% （70/120）. Conclusion: Patients with MECwTS exhibit more severe middle ear and mastoid pathology compared to those with MECw/oTS, resulting in poorer postoperative hearing levels and quality of life outcomes. Both PORP and TORP implantation can improve postoperative hearing to some extent; however, PORP appears to offer superior hearing improvement efficacy compared to TORP.

Objective:This study aims to investigate the therapeutic efficacy of staged endoscopic surgery for Shin-Ⅲ stage external auditory canal cholesteatoma. Methods:A retrospective analysis was conducted on the clinical data of 25 patients diagnosed with Shin-Ⅲ cholesteatoma of the external auditory canal, who were admitted to the Otology Center of the First People's Hospital of Foshan City from May 2020 to October 2024. All patients initially underwent endoscopic cholesteatoma removal. Based on the outcomes of the first-stage postoperative follow-up, patients were categorized into two groups: the repair type and the non-repair type. The non-repair type was further subdivided into simple and complex types. Of the total cases, 10 patients were of the repair type, with 9 requiring no further surgical intervention. The non-repair type comprised 15 patients, of which 8 were classified as simple type and underwent either tympanoplasty type Ⅰ or external auditory canal wall reconstruction during the second stage. The remaining 7 patients, identified as complex type, received open mastoidectomy or tympanotomy in the second stage, with or without ossicular chain reconstruction. Results:All patients were monitored for a minimum of six months postoperatively. The incidence of dry ear was observed in 22 patients, corresponding to a dry ear rate of 88.0%. Four cases experienced primary complications. Conclusion:Endoscopic phased operation for managing Shin-Ⅲ stage cholesteatoma of the external auditory canal can ensure that the surgical options match the severity of the lesions, reducing unnecessary surgical trauma and achieving good efficacy.

Objective:To explore the application value of high-resolution temporal bone CT and DW-MRI fusion technology in achieving precise diagnosis and anatomical localization of middle ear cholesteatoma during endoscopic surgery. Methods:Eighteen patients initially diagnosed with middle ear cholesteatoma in the Department of Otolaryngology Head and Neck Surgery, Shaanxi Provincial People's Hospital, from January to June 2024 were enrolled.Preoperative high-resolution temporal bone CT and DW-MRI were performed, and rtStation software was used for image fusion to construct CT-MRI fused images. The involvement of cholesteatoma in six anatomical subregions of the temporal bone was evaluated. Using surgical pathology as the gold standard, and combining surgical videos and anatomical records, the sensitivity, specificity, and accuracy of pure CT, pure DW-MRI, and CT-MRI fused images in evaluating middle ear cholesteatoma lesions were compared. Results:A total of 18 patients were included, and 17 cases were pathologically confirmed as middle ear cholesteatoma postoperatively. The sensitivity of the preoperative of preoperative CT was 100%, but the specificity was only 44.44%, with an overall accuracy of 72.22%; the sensitivity and specificity of DW-MRI evaluation were 81.46% and 85.19%, the accuracy was 83.33%, respectively. In contrast, the sensitivity and specificity of CT-MRI fusion image to the spatial localization of cholesteatoma were higher than that of DW-MRI alone（92.59% vs 81.46%; 98.15% vs 85.19%）, and the diagnostic accuracy was also significantly improved（95.37% vs 83.33%）. The Kappa values for the agreement between HRCT, DW-MRI, and CT-MRI segmentation localization and pathological results were 0.444, 0.667, and 0.907 respectively. The chi-square paired t-test confirmed statistically significant diagnostic differences between groups（P<0.001）. Results demonstrated that CT-MRI significantly outperformed HRCT and DW-MRI in diagnostic efficacy for segmental localization of primary posterior congenital middle ear cholesteatoma. Conclusion:High-resolution temporal bone CT combined with DW-MRI fusion technology demonstrates higher sensitivity, specificity, and accuracy in the diagnosis and spatial localization of middle ear cholesteatoma than single imaging modalities. It can provide more precise evaluation of lesion scope for endoscopic surgery, showing important clinical application value.
