The study was performed to investigate the effect of bromelain as an antioxidant and anti-inflammatory on myringotomized rats. Methods: The myringotomy operations of 15 Wistar Albino rats were performed under an otomicroscope. Three groups were formed by randomly separating these animals. The day after unilateral myringotomy, the control group was injected with 0.9% NaCl (saline) intraperitoneally (i.p.). The rats of the second group were injected 15 mg/kg/day of bromelain i.p. The third group received 30 mg/kg/day of bromelain i.p. On the 22nd day, the myringotomized ears of the animals were investigated via otomicroscope to determine myringosclerosis. After euthanasia of the animals, tympanic membrane (TM) thickness and inflammation of middle ear mucosa were investigated histopathologically. Results: The control group had higher myringosclerosis scores than the bromelain curative groups (P=.048). The median TM thickness of the control group (64.75 µm) was higher than the bromelain 15 mg/kg group (34.95 µm) (P=.009) and the bromelain 30 mg/kg group (27.84 µm) (P=.008). The inflammation scores were higher in the control group compared to the bromelain curative groups (P=.039). There were no statistically significant differences according to myringosclerosis scores (P=.117), TM thickness (P=.079), and inflammation scores (P=.490) between the bromelain low and high dose groups. Conclusion: Bromelain treatment prevented the formation of myringosclerosis, reduced TM thickness, and supressed inflammation in myringotomized rats.","PeriodicalId":94238,"journal":{"name":"The journal of international advanced otology","volume":"21 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11843273/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If the physiological functions of the eustachian tube are impaired, ear diseases may occur. There are many test methods used to evaluate the functions of the eustachian tube. However, none of these methods are accepted as the gold standard due to both the application difficulties of these methods and the reliability of their results. We aim to use tubomanometry for the detection of eustachian tube dysfunction (ETD) and so to increase the success rates of ear surgeries in patients diagnosed with tubal dysfunction with easily applicable methods. Methods: In this prospective study, the tubomanometry results of 34 patients diagnosed with chronic otitis media who underwent tympanoplasty were compared with 34 healthy controls. The tubomanometry measurements of patients diagnosed with chronic middle ear disease (affected ear side) and the control group (healthy ears) were compared. Results: A statistically significant increase in mean rising time was found between the control group and the patient group at first month postoperative, sixth month postoperative (P < .01). In the control group, eustachian function was found to be normal (R < 1) compared with that of the all patient groups (P < .01, first month postoperative comparison P < .05). Conclusion: In the application of surgical methods used in the treatment of ETD, the ETD must first be determined with an objective test tool. According to the results of our study, one of the most objective tests that can be used in this regard is tubomanometry.","PeriodicalId":94238,"journal":{"name":"The journal of international advanced otology","volume":"21 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11843269/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, timely access to healthcare guidance can be challenging, especially in rural or underserved areas. ChatGPT-4, an artificial intelligence (AI) tool, offers a potential solution for continuous postoperative support and patient education. This study assesses the feasibility and effectiveness of using ChatGPT-4 as a supplementary information resource for tympanoplasty patients, focusing on its ability to provide accurate, precise, and relevant postoperative guidance in situations where access to healthcare professionals is limited. Methods: Ten commonly asked postoperative questions related to tympanoplasty were posed to ChatGPT-4, including queries on infection signs, activity restrictions, and wound care. Ten medical professionals evaluated the responses based on accuracy, response time, clarity, and relevance. Results: ChatGPT-4 provided responses that aligned well with current medical guidelines, achieving an accuracy rating between 80% and 100% across different questions. Response time was consistently fast, with 100% of responses delivered immediately. Clarity and relevance ratings were also high, with 90% or more responses rated as easy to understand and directly addressing patient concerns. Conclusion: ChatGPT-4 shows considerable promise as an adjunctive tool in postoperative tympanoplasty care, offering timely, understandable information that supports patients following aftercare instructions. While not a replacement for professional medical advice, ChatGPT-4's capability to deliver accurate and relevant information enhances accessibility to postoperative guidance, particularly in remote or resourcelimited settings, underscoring AI's growing role in otolaryngology patient support.","PeriodicalId":94238,"journal":{"name":"The journal of international advanced otology","volume":"21 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11843261/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluates the utility of this imaging technique in the first 100 patients scanned at our tertiary center. Methods: A retrospective study was conducted in the Department of Otology and Neuro-otology at University College London Hospitals between October 2020 and May 2022. Patients were classified into 4 groups: \"definite MD,\" \"probable MD,\" isolated cochlear symptoms, and MD-vestibular migraine (VM) overlap syndrome. The local imaging protocol consisted of an intravenous gadolinium (IV-Gd) injection followed by T2 SPACE and 3D-real inversion recovery magnetic resonance imaging (MRI) of the inner ears after 4 hours. Results: The first 100 patients scanned were included. All patients with \"definite MD\" and MD-VM overlap syndrome had evidence of radiological EH on MRI. About 38% of patients in the \"probable MD\" group and 25% of patients in the isolated cochlear hydrops group had radiological EH. For the \"definite MD\" group, 98% of positive scans correlated with disease laterality; this was 87% in the \"probable MD\" group. Duration of disease >4 years and more severe hearing loss were found to be statistically significant factors for the detection of EH. Conclusion: Our study demonstrates that EH is much more likely to be detected in patients with a clinical diagnosis of \"definite MD\" or MD-VM overlap syndrome, and also correlates with the increasing duration and severity of symptoms. Further studies using standardized imaging protocols would be helpful in comparing outcomes.","PeriodicalId":94238,"journal":{"name":"The journal of international advanced otology","volume":"21 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11843304/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ICSs are particularly rare in the pediatric population. Putative diagnosis is made on the basis of magnetic resonance findings with signal characteristics that should remain the same at follow-up imaging.Methods: A retrospective review was performed searching for pediatric patients affected by ICS treated at the Otolaryngology Department, Ospedale Ramazzini, Carpi (Italy), and Otolaryngology and Otoneurosurgery Department, Azienda Ospedaliero-Universitaria di Parma, (Italy). A scoping literature review of the period January 2000 - June 2024 was performed.Results: Two cases of ICS in pediatric patients are described. Neither family history nor genetic signs of neurofibromatosis type II were found. A single report was identified in the literature review. Data analysis resumes the pooled data of the latter case and the authors' patients. The most common symptom at presentation was progressive sensorineural hearing loss (66%). Mean pure tone average at diagnosis was 74.2 dB. Intracochlear location was in the basal turn in 2 cases and in the apical and middle turns in the third patient. All cases initially underwent a \"wait and scan\" strategy. The mean follow-up time was 23.3 months.Conclusion: Management planning of pediatric ICSs should be accurate as surgical removal may require partial or total cochlear demolition, resulting in vestibular dysfunction and precluding future positioning of a cochlear implant. Close clinical and radiological follow-up with serial MRI scans allows to evaluate both symptom progression and rate of growth, in order to provide patients with the best therapeutic option.","PeriodicalId":94238,"journal":{"name":"The journal of international advanced otology","volume":"20 6","pages":"484-488"},"PeriodicalIF":0.0,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11639579/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142809043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They often cause no symptoms for a long period of time. Due to the improved availability and quality of magnetic resonance imaging diagnostics, even small tumors can be diagnosed at an early stage. The fact that the diagnosis of a VS might negatively affect a patient's quality of life (QoL) should be taken into consideration when informing patients about various treatment options. However, little is known about the level of QoL in patients with small VS prior to scheduled surgery.Methods: One hundred forty- one patients with a T1 or T2 VS that had been scheduled for microsurgery via the middle cranial fossa (MCF) approach between 01/2013 and 12/2018 were included. Quality of life was evaluated using the Short-Form-36 (SF-36) survey. Eighty-one patients completed the questionnaire. Additionally, audiological and clinical data were collected.Results: When compared to the German normative QoL data, VS patients showed a significant deterioration in quality of life in 6 of the 8 SF-36 subscales, whereas only 4 of 8 subscales were affected when compared to the normative group of patients with hearing loss. The analysis of predictors did not show any significant relationship between tumor volume, facial nerve function, and QoL. Only preoperative hearing status and sex had a slight impact on one subscale each (emotional health and physical health, respectively).Conclusion: This study shows that patients with small VS have an impairment in QoL before surgical treatment.

Therefore, we investigated factors that worsen speech discrimination when the speech sound level increases.Methods: Speech discrimination was measured in patients aged >20 years who had average hearing thresholds <90 dB on pure-tone audiometry. An insufficient benefit was defined as speech discrimination being better at 65 dB sound pressure level (SPL) with HAs than without HAs and worse at 80 dB SPL.Results: Of the 251 participants (296 ears), 229 and 25 had sufficient benefit and insufficient benefit, respectively. Functional gains (FGs) of sufficient benefit were approximately 1/3 gain (1/3 G) at 500 and 4000 Hz and slightly larger at 1000 and 2000 Hz. Functional gains of insufficient benefit were approximately 1/2 G at 1000 and 2000 Hz, smaller at 500 and 4000 Hz, and approximately 1/3 G at 250 Hz. Moreover, the difference between 1/2 G and FG was significantly larger in the sufficient benefit group at 250 500, and 4000 Hz than in the insufficient benefit group. Additionally, the average compression ratio at 50-80 dB SPL in the insufficient benefit group was approximately 1.1 to 1.2, slightly lower than the standard values.Conclusion: Adjusting the compression ratio and lowering the FG to approximately 1.5 and 1/3 G, respectively, may help improve speech discrimination if it worsens with increasing sound levels during HA fitting.","PeriodicalId":94238,"journal":{"name":"The journal of international advanced otology","volume":"20 6","pages":"502-506"},"PeriodicalIF":0.0,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11648699/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142809041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
