Auris Nasus Larynx最新文献

Objective

There is no consensus on the optimal surgical technique for allergic rhinitis (AR). Furthermore, the appropriateness of surgical intervention in children and older individuals remains debatable. This study aimed to analyze trends and patterns in the surgical management of AR in Japan, focusing on parasympathetic neurectomy.

Methods

Using the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB), we conducted a comprehensive review of procedures performed between April 2014 and March 2022. In addition, a cross-sectional survey targeting otolaryngologists across Japan was conducted to gather insights into surgical preferences and practices.

Results

The NDB data showed an increasing trend in neurectomies, with the most frequent age group being 25–29 years; the procedure was also performed in pediatric and older patients. The survey among otolaryngologists indicated that 58.2 % of surgeons preferred peripheral branch neurectomy of the posterior nasal nerve. The findings of this study also indicated a cautious approach toward conducting these procedures in children, with 51.2 % of surgeons considering patients less than 18 years of age unsuitable for the procedure.

Conclusion

This study highlighted a shift toward simple and minimally invasive surgical methods, such as peripheral branch neurectomy, in Japan. However, further research is needed to understand the long-term outcomes and refine the surgical techniques. The findings of this study also emphasized the need for age-specific considerations when treating pediatric and older patients with AR.

Pulmonary tumor thrombotic microangiopathy (PTTM) is a rapidly progressive cancer-related disease with a dismal clinical course. The patient in this report was a 43-year-old man with metastatic salivary duct carcinoma arising from the parotid gland. Combined androgen blockade therapy was administered started as first-line treatment, but failed after 5 months, followed by docetaxel plus carboplatin therapy as second-line treatment, which failed after 3 months. Genomic profiling revealed a BRAF V600E mutation, and combined BRAF and MEK inhibitor therapy was started as third-line treatment. The cancer remained stable during the first 10 months of third-line treatment, but treatment was subsequently discontinued due to the onset of symptoms of fatigue, myalgia and arthritis. Twenty days after the onset of these symptoms and interruption of third-line treatment, the patient was urgently admitted to hospital with respiratory distress and severe thrombocytopenia. CT images at the time of admission led our radiologist to the possibility of PTTM, but the patient died the day after admission and autopsy findings indicated that PTTM was the cause of death. This report describes a very informative case of PTTM with sequential imaging and detailed autopsy findings were available and provides a literature review.

Objective

The hearing aid adoption rate among older adults in Japan is lower than that in other developed countries. Herein, a survey was conducted to identify this bottleneck and develop countermeasures. This study aimed to examine whether raising awareness of the relationship between hearing loss and dementia is significant for hearing tests and adopting hearing aids.

Methods

A questionnaire was administered to participants aged 65 or older who visited a general hospital to determine the background factors (1) for a recent history of hearing tests, (2) for the desire to visit an otolaryngologist and have a hearing test, (3) for recognizing the hearing loss–dementia relationship, and (4) for adopting hearing aids.

Results

A total of 517 patients (mean age, 78.06; SD 6.97), representing 2.4% of the region's older-adult population, participated in the survey. A history of hearing tests within five years was significantly associated with recognizing the hearing loss–dementia relationship (adjusted OR 2.36, 95% CI 1.49–3.72). The desire to visit an otolaryngologist or have a hearing test was significantly associated with recognizing the hearing loss–dementia relationship (adjusted OR 1.70, 95% CI 1.02–2.85). Moreover, 39.3% were aware of the hearing loss–dementia relationship. The significant associated factors were being female (OR 2.50, 95% CI 1.64–3.81) and having interpersonal hobbies (OR 1.66, 95% CI 1.11–2.49). The significant background factors for adopting hearing aids were older age (OR 6.95, 95% CI 1.90–25.40), self-reported severe hearing impairment (OR 5.49, 95% CI 2.55–11.80), and living alone (OR 2.63, 95% CI 1.18–5.89). Recognizing the hearing loss–dementia relationship was not a significant factor.

Conclusion

Raising awareness of the hearing loss–dementia relationship was not associated with adopting hearing aids for self-reported hearing impairments. However, it may be associated with otolaryngology visits and hearing tests. Thus, steps like hearing screening for older adults are also essential.

Objective

Acute sensorineural hearing loss represents a spectrum of conditions characterized by sudden onset hearing loss. The “Clinical Practice Guidelines for the Diagnosis and Management of Acute Sensorineural Hearing Loss” were issued as the first clinical practice guidelines in Japan outlining the standard diagnosis and treatment. The purpose of this article is to strengthen the guidelines by adding the scientific evidence including a systematic review of the latest publications, and to widely introduce the current treatment options based on the scientific evidence.

Methods

The clinical practice guidelines were completed by 1) retrospective data analysis (using nationwide survey data), 2) systematic literature review, and 3) selected clinical questions (CQs). Additional systematic review of each disease was performed to strengthen the scientific evidence of the diagnosis and treatment in the guidelines.

Results

Based on the nationwide survey results and the systematic literature review summary, the standard diagnosis flowchart and treatment options, including the CQs and recommendations, were determined.

Conclusion

The guidelines present a summary of the standard approaches for the diagnosis and treatment of acute sensorineural hearing loss. We hope that these guidelines will be used in medical practice and that they will initiate further research.

Objective

The Hounsfield unit density value (HUDV) is a relative quantitative measurement of radio density used by radiologists in the interpretation of computed tomography (CT) images. Our aim is to investigate the role of HUDV in evaluating pre-epiglottic space (PES) involvement of laryngeal carcinoma.

Methods

Seventy-four patients treated for laryngeal carcinoma in our clinic between 2014 and 2019 were included in the study. The invasion status of PES was determined radiologically and pathologically. HUDV was measured with a circular selected region of interest, with a constant size of 10 mm² for PES. The relationship between patological PES invasion, radiological PES invasion, and HUDV was evaluated.

Results

Measuring HUDV to determine PES invasion (74.3 %) was significantly higher than​​ conventional CT evaluation (59.5 %) (p = 0.001). The agreement coefficient (kappa value) of the conventional CT evaluation and the HUDV regarding PES involvement was 0.673, which was interpreted as ‘good’.

Conclusion

HUDV could be used as an additional tool in diagnosing pre-epiglottic space invasion in laryngeal cancer.

Objective

This study aimed to determine which comorbidities were associated with intractable epistaxis requiring electrocauterization or embolization, and to identify the location where intractable epistaxis frequently occurred.

Methods

The patients were divided into two groups: patients with epistaxis successfully controlled in outpatient department (OPD) and those with intractable epistaxis in OPD which was controlled by surgical exploration or arterial embolization (OP/EM). Evaluations of the bleeding locations, related vessels, and patient's comorbidities were conducted.

Results

A total of 41 patients from the OP/EM group and 725 patients from the OPD group were enrolled. The following comorbidities showed elevated risks of the intractable epistaxis (p< 0.05) in multivariate analysis; hypertension (OR 1.089, 95% CI 1.049 - 1.132), dyslipidemia (1.132, 1.041 - 1.232), liver cirrhosis (1.272, 1.152 - 1.406), chronic obstructive pulmonary disease (1.234, 1.078 - 1.412) and asthma (1.205, 1.053 - 1.379). Inferior and middle turbinate were equally the most common location of the intractable bleeding.

Conclusion

In patients with epistaxis requiring hemostatic treatments, comorbidities such as hypertension, dyslipidemia, liver diseases, COPD, and asthma were associated with intractable epistaxis. The main bleeding sites of intractable epistaxis were the middle and inferior turbinate.

Objective

Laryngeal preservation and a radical cure are the treatment goals for laryngeal carcinoma, and larynx-preserving therapy is generally preferred for early-stage laryngeal carcinoma. When laryngeal carcinoma recurs locally, patients are often forced to undergo total laryngectomy, resulting in loss of vocal function. However, many patients with laryngeal carcinoma who have residual or recurrent disease after radiotherapy wish to preserve their voice. The purpose of this study was to investigate the possibility of using BNCT as a larynx-preserving treatment for residual or recurrent laryngeal carcinomas following radical irradiation.

Patients and Methods

This study included 15 patients who underwent BNCT for residual or recurrent laryngeal carcinoma after radical laryngeal carcinoma irradiation. The number of treatment sessions for all patients was one irradiation. Before BNCT, the recurrent laryngeal carcinoma stage was rT1aN0, rT2N0, rT2N1, rT3N0, rT3N1, and rT4aN0 in one, six, one, three, one, and three patients, respectively. The median maximum tumor diameter before BNCT was 15 mm (8–22 mm). All patients underwent a tracheostomy before BNCT to mitigate the risk of upper airway stenosis due to laryngeal edema after BNCT. Treatment efficacy was evaluated retrospectively using monthly laryngoscopy after BNCT and contrast-enhanced CT scans at 3 months. The safety of treatment was evaluated based on examination findings and interviews with patients.

Results

The median hospital stay after BNCT was 2 days (1–6). The response rate at three months after BNCT in 15 patients with locally recurrent laryngeal carcinoma was 93.3 %, and the CR rate was 73.3 %. The most frequent adverse event associated with BNCT was laryngeal edema, which occurred in nine patients the day after BNCT. The average course of laryngeal edema peaked on the second day after BNCT and almost recovered after 1 week in all patients. One patient had bilateral vocal fold movement disorders. None had dyspnea because of prophylactic tracheostomy. No grade four or higher adverse events occurred. Other grade 2 adverse events included pharyngeal mucositis, diarrhea, and sore throat. Three months after BNCT, tracheostomy tubes were removed in nine patients, retinal cannulas were placed in three patients, and voice cannulas were placed in three patients.

Conclusions

BNCT for locally recurrent laryngeal carcinoma can safely deliver radical irradiation to tumor tissues, even in patients undergoing radical irradiation. BNCT has shown antitumor effects against recurrent laryngeal carcinoma. However, further long-term observations of the treatment outcomes are required.

Objective

This study aims to evaluate the presence of residual Plus Moist HS-W (PM), a novel calcium alginate packing material, during the initial postoperative visit following endoscopic sinus surgery. The research aims to identify factors that influence the quantity of remaining PM.

Methods

A retrospective review of medical records was conducted for patients who underwent middle meatus packing with PM.

Results

A total of fifty-two patients (representing 92 sides of paranasal sinuses) were included in the analysis. The remaining PM was classified as follows: absent (0) in 41 out of 92 cases, minimal (1) in 22 out of 92 cases, moderate (2) in 15 out of 92 cases, and substantial (3) in 14 out of 92 cases. Notably, all three patients who underwent Draf III surgery exhibited a significant amount of PM during their initial visit, with two patients classified as grade 2 and one patient as grade 3. Other factors investigated were found to be unrelated to the persistence of PM. Removal of all PM was achieved effortlessly using suction under flexible endoscopy.

Conclusion

This study highlights the efficacy of PM in post-endoscopic sinus surgery care. It is important to limit an amount of PM, particularly in Draf III procedures.

Objective

Knowledge about voice prosthesis microbial colonization is vital in laryngectomized patients’ quality of life (QoL). Herein, we aimed to explore the relationship between oral microbial patterns, demographic variables and voice prosthesis performance.

Methods

Thirty laryngectomy patients were assessed for microbial colonization in their voice prostheses and oral cavities. Factors like age, proton pump inhibitor (PPI) usage, and alcohol consumption were considered.

Results

Participants' average age was 74.20 ± 7.31 years, with a majority on PPIs. Staphylococcus aureus was the most common bacterium in prostheses (53 %), followed by Pseudomonas aeruginosa (27 %). Candida albicans was the primary fungal colonizer (67 %). A statistically significant moderate correlation was found between fungal species before and after oral rinsing (p = 0.035, Phi=0.588, Cramer's V = 0.416). Voice prosthesis and oral cavity microbiota profiles showed significant concordance (kappa=0.315, p < 0.004). Among subgroup analyses, bacterial patterns of colonization did not significantly influence VHI (p = 0.9555), VrQoL (p = 0.6610), or SF-36 (p = 0.509) scores. Conversely, fungal patterns of VP colonization significantly impacted subjective voice scores, with Candida krusei demonstrating better VHI (35.25 ± 3.63 vs. 44.54 ± 6.33; p = 0.008), VrQoL (7.13 ± 1.69 vs. 10.73 ± 2.00; p = 0.001), and SF-36 (69.36 ± 7.09 vs. 76.50 ± 7.73; p = 0.051) scores compared to C. albicans.

Conclusions

There was a significant correlation between the oral microbiota and voice prosthesis colonization. These insights can inform improved care strategies for voice prostheses, enhancing patient outcomes.

Tonsillar focal diseases (TFDs) are defined as “diseases caused by organic and/or functional damage in organs distant from tonsil, and the disease outcome is improved by tonsillectomy.” Although several reports and reviews have shown the efficacy of tonsillectomy for TFDs, no guidelines for the clinical management of the diagnosis and treatment of TFDs have been reported. Therefore, the Society of Stomato-pharyngology established a committee to guide the clinical management of patients with TFDs, and the original guide was published in May 2023. This article summarizes the English version of the manuscript. We hope that the concept of TFDs will spread worldwide, and that one as many patients with TFDs will benefit from tonsillectomy.
