Background and Objectives Central compartment atopic disease (CCAD) has been studied with increasingly more importance as a distinct subtype of chronic rhinosinusitis with nasal polyp (CRSwNP). Studies have shown that CCAD in Western populations show a strong association with allergy and typical features of medial nasal structure and sinus involvement. The purpose of this study was to evaluate the clinical characteristics of CCAD and compare them to those of other subtypes of CRS in Korea.Subjects and Method A chart review was performed retrospectively at two tertiary rhinologic centers for patients who were treated with bilateral endoscopic sinus surgery for CRS with or without nasal polyp from January 2019 to December 2021. Patients were divided into three groups, namely CCAD, CRSwNP, and CRS without nasal polyps (CRSsNP), and demographics, clinical characteristics, and imaging data were compared among the three groups.Results A total of 150 patients were included in this study (50 patients in each group). CCAD showed similar nasal symptoms with CRSwNP, but higher rates of olfactory impairment than CRSsNP did. Allergy prevalence, serum total immunoglobulin E, and serum eosinophil were significantly higher in CCAD than in CRSwNP or CRSsNP. In CT scans of paranasal sinuses, CCAD showed significantly less haziness of maxillary sinus and higher ethmoid/maxillary score ratio than the other two groups. In addition, CT scans showed mucosal involvements of central compartment in CCAD.Conclusion CCAD has characteristic endoscopic and imaging findings, showing a high prevalence of allergy and a strong association with the markers of type 2 inflammation. Therefore, CCAD is a distinct disease of CRSwNP and its allergic etiology should be considered in the management of patients with CCAD phenotype.

Beta blockers are used for various indications, particularly cardiac arrhythmias, cardioprotection after myocardial infarction, hypertension, migraine, tremor, and anxiety disorders, by inhibiting the sympathetic actions of catecholamine hormones (i.e., epinephrine and norepinephrine). This sympathetic mechanism occurs via beta-adrenergic receptors. Recently, experimental evidence showed that malignant cell lines express beta-adrenergic receptors and that sympathomimetic neurotransmitters may affect carcinogenesis through these receptors. These neurotransmitters are suggested to have a major impact on secondary tumor growth and to contribute to metastasis, induction of angiogenesis, and tissue invasion. Given that beta-blockers are considered safe, cheap, and effective, the potential beneficial effects of their use for cancer would be of interest. However, evidence from epidemiological and clinical studies has been inconclusive. Especially the effect of beta-blockers on head and neck cancer has rarely been investigated.

Background and Objectives This study focused on predicting voice outcomes following hemithyroidectomy using skin electrode intraoperative neuromonitoring (IONM).Subjects and Method The study involved 82 patients who underwent hemithyroidectomy. During the surgery, the researchers recorded skin IONM values for the vagus nerve and recurrent laryngeal nerve. Voice quality evaluations were conducted before the surgery and at various intervals after the surgery (one week, one month, three months, six months, and one year) using the multidimensional voice program (MDVP), voice handicap index (VHI), and the grade, roughness, breathiness, asthenia, strain (GRBAS) scale. The study aimed to correlate perioperative skin IONM values with subjective and objective voice outcomes.Results The VHI scores increased up to three months post-surgery, with statistically significant changes observed at one week post-surgery. The GRBAS scale scores also increased significantly at one month post-surgery. Similar trends were observed in the MDVP data, including a decrease in the maximum pitch between one week and three months post-surgery. Additionally, the study found that lower delta-V values (difference between the preoperative and postoperative signal amplitude of vagus nerve stimulation) were associated with higher F0 values at one week and three months post-surgery, while jitter and noise-to-harmonic ratio were higher in the group with higher delta-V values at three months post-surgery.Conclusion Greater differences between the preoperative and postoperative signal amplitude of vagus nerve stimulation during surgery were linked to worse postoperative voice outcomes. Voice parameters worsened for up to 3 months after hemithyroidectomy but showed signs of recovery afterwards. These findings offer insights into predicting and managing voice outcomes after hemithyroidectomy.

The majority of tympanoplasty procedures have been performed using the retroauricular approach to improve visualisation of the anterior tympanic membrane. The classic retroauricular approach requires elevation of the Körner flap and tympano-meatal flap through the ear canal skin incision. This step can lead to the exposure of the bones in the ear canal, resulting in delayed wound healing and pain, especially in elderly or immunocompromised patients. Endoscopic ear surgery is a minimally invasive procedure that offers a wider field of view, but has the disadvantage of being a one-handed operation and cannot avoid skin incisions in the ear canal for tympanoplasty. Here we present a hybrid retroauricular approach without skin incision of the ear canal, using both microscope and endoscope. This method provides very fast wound healing and significantly less pain.

Tinnitus, defined as the perception of sound in the absence of any external stimuli, is a condition which affects a significant number of people worldwide. Although the pathophysiology of tinnitus is not fully understood, hearing loss is known to be a major contributor. To date, many studies have investigated the relationship between hearing loss and cognitive function, and hearing loss is now considered a modifiable risk factor for cognitive decline. In this context, recent studies have investigated whether tinnitus, which is closely associated with hearing loss, is also a risk factor for cognitive decline. However, conflicting results have been reported regarding the relationship between these two conditions. Several studies have reported cognitive decline in tinnitus patients, particularly in areas related to working memory and attention. The consideration of patient age is crucial, as older people seem to be more affected by tinnitus-related cognitive issues. In contrast, some studies have indicated no direct association between tinnitus and cognitive decline, with some even indicating potential cognitive improvement in tinnitus patients. In this article, we review the current research on the relationship between tinnitus and cognitive function and discuss the potential association between these two conditions.

The olfaction is not a degraded sense, but it plays an important function not only in survival but also in human senses, emotions, memories, and social functions. It is a complex and difficult characteristic of the olfaction that has only recently been scientific development. Although interest has increased recently, the characteristics and functions of human olfactory function are not well known, and medical research are also focused on disease. In fact, interest in medical aspects such as the cause of olfactory diseases, olfactory function tests, treatments, and olfactory rehabilitation has only recently grown, and other odors, olfactory characteristics, functions, and humanities have little interest. Therefore, beyond the medical perspective on human olfaction and smell, we intend to increase our understanding and interest in the olfaction, which has been underestimated in importance, through humanistic considerations. The olfaction is also a sense of a person, and its value should be paid attention again. It’s never an inferior sense. Understanding the functions of the underrated human olfaction and re-discovering the lost olfaction and smell culture will enrich life.

An implantable bone conduction hearing aid is a device that assists hearing by transmitting sound vibration through the bone. It is suitable not only for patients with conductive hearing loss and congenital external aural atresia but also for those with unilateral hearing loss, chronic otitis media, or patients whose normal structure has been destroyed due to previous surgery. In this paper, we introduce a novel surgical technique for an implantable bone conduction hearing aid (BAHA® Attract) that can be performed through minimal incision in a short time under local anesthesia based on accurate anatomical characteristics. We believe this novel technique could provide convenience for patients and surgeons. Additionally, through this technique, we can expect that various types of implantable bone conduction hearing aids that function effectively and safely can be provided for patients.

Congenital cholesteatoma is rare, and especially so for a benign mass to grow from the squamous epithelium and the petrous apex as a location for this cancer. Surgery of the petrous apex cholesteatoma is challenging due to the location of the lesion and the need to preserve adjacent structures such as the dura mater, internal carotid artery, and internal auditory canal. Imaging studies, including CT and MRI, were crucial in guiding the surgical approach. This report describes a 40-year-old male patient with a large congenital cholesteatoma involving the petrous apex and temporal bone. The patient presented with a headache, hearing loss that persisted despite prior medical treatment. The cholesteatoma was surgically marsupialized through translabyrinthine approach, and the patient has remained stable for over 20 years. This report underscores the importance of considering the anatomical location and relationships of the lesion and adjacent structures when determining the surgical approach for congenital cholesteatoma involving the petrous apex and temporal bone.

Background and Objectives The hearing in noise test (HINT) or sound localization test (SLT) is used as the standardized assessment for contralateral routing of signals (CROS) and bilateral microphones with contralateral routing of signals (BiCROS) hearing aids (HAs). However, implementing HINT or SLT can be challenging in most ENT clinics. In this study, we propose a new feasible method specifically designed for conducting a sound field hearing test for CROS and BiCROS HA users.Subjects and Method CROS/BiCROS HA users who visited Seoul St. Mary’s hospital between 2019 and 2021 were enrolled for the study. SLT was conducted in a sound-proof room equipped with two speakers positioned at a 45° angle from the patient on each side: noise stimuli were presented to the better ear the headphone patient was wearing while signals were presented to the worse ear via the speakers in the room. To validate the sound field test, a correlation analysis was conducted using the Bern benefit in single-sided deafness and the Korean version of the International Outcome Inventory for Hearing Aids (K-IOI-HA) Questionnaires.Results The aided speech discrimination score was significantly higher in the signal 60 dB HL/masking 50 dB HL condition than 50 dB HL/masking 50 dB HL condition (p<0.05). A significant correlation was found between the gain of sound field speech audiometry and the K-IOI-HA questionnaire (p<0.05).Conclusion Our novel sound field hearing test for CROS/BiCROS HA users, which presents appropriate noise stimuli via headphones to the better ear, appears to be a feasible approach for CROS/BiCROS HA users.
背景与目的采用噪声听力测试(HINT)或声音定位测试(SLT)作为对侧信号走线(CROS)和双侧麦克风配对侧信号走线(BiCROS)助听器(HAs)的标准化评估。然而，在大多数耳鼻喉科诊所实施HINT或SLT可能具有挑战性。在这项研究中，我们提出了一种新的可行的方法，专门设计用于进行声场听力测试的CROS和BiCROS HA用户。在2019年至2021年期间访问首尔圣玛丽医院的CROS/BiCROS HA用户被纳入研究。SLT是在一个隔音的房间里进行的，房间两边各有两个扬声器，与患者成45°角。噪音刺激被呈现给患者戴耳机的较好的耳朵，而信号通过房间里的扬声器呈现给较差的耳朵。为了验证声场测试，使用单侧耳聋的Bern效益和韩国版助听器国际结果清单(K-IOI-HA)问卷进行了相关分析。结果在信号60 dB HL/屏蔽50 dB HL条件下，辅助语音识别得分显著高于50 dB HL/屏蔽50 dB HL条件(<i>p</i><0.05)。声场语音测听增益与K-IOI-HA问卷存在显著相关(<i>p</i><0.05)。结论本文提出的新型CROS/BiCROS HA使用者声场听力测试方法，通过耳机向右耳提供适当的噪声刺激，对于CROS/BiCROS HA使用者是一种可行的方法。

However, implementing HINT or SLT can be challenging in most ENT clinics. In this study, we propose a new feasible method specifically designed for conducting a sound field hearing test for CROS and BiCROS HA users.Subjects and Method CROS/BiCROS HA users who visited Seoul St. Mary’s hospital between 2019 and 2021 were enrolled for the study. SLT was conducted in a sound-proof room equipped with two speakers positioned at a 45° angle from the patient on each side: noise stimuli were presented to the better ear the headphone patient was wearing while signals were presented to the worse ear via the speakers in the room. To validate the sound field test, a correlation analysis was conducted using the Bern benefit in single-sided deafness and the Korean version of the International Outcome Inventory for Hearing Aids (K-IOI-HA) Questionnaires.Results The aided speech discrimination score was significantly higher in the signal 60 dB HL/masking 50 dB HL condition than 50 dB HL/masking 50 dB HL condition (<i>p</i><0.05).
