Abstract Objective: To evaluate the therapeutic efficacy of intratympanic dexamethasone (ITD) injections added to systemic steroids in patients with idiopathic sudden sensorineural hearing loss (HL). Materials and Methods: A total 120 diagnosed HL were treated ITD (0.3 mL on days 1, 3, 5) plus 48 mg methylprednisolone (ITD group) or alone (control group). Results: The recovery rate after treatment was 73.3% group 70.0% control group. Although improvements pure‐tone average same two groups,...
BackgroundAlthough previous studies have suggested that linezolid may be effective for treating multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB), the optimal dose of intractable MDR/XDR-TB is not clear.
Vestibular migraine (VM) is one of the most common causes episodic vertigo. We reviewed results multiple vestibular function tests in a cohort VM patients who were diagnosed with according to diagnostic criteria Barany Society and International Headache assessed efficacy each for predicting prognosis patients. A retrospective chart analysis was performed on 81 at tertiary care center from June 2014 July 2015. Patients by video head impulse test (vHIT), caloric test, vestibular-evoked...
Abstract Given our aging society and the prevalence of age-related hearing loss that often develops during adulthood, is a common public health issue affecting almost all older adults. Moderate-to-moderately severe can usually be corrected with aids; however, severe-to-profound requires cochlear implant (CI). However, post-operative CI results vary, performance previous prediction models limited, indicating new approach needed. For postlingually deaf adults (n de120) who received full...
The antrochoanal polyp (ACP) is defined as a maxillary sinus that originates in the sinus, passes through ostia, and extends into choana. aim of this study was to compare histologic findings 40 cases ACP with those allergic non-allergic nasal polyps, so possibly elucidate pathogenesis ACP. No allergy could be verified any patients. Inflammatory cell infiltration significantly more severe group than group. Eosinophilic less Edema not different between ACP, allergic, groups. In group, presence...
Precise evaluation of the tympanic membrane (TM) is required for accurate diagnosis middle ear diseases. However, making an assessment sometimes difficult. Artificial intelligence often employed image processing, especially performing high level analysis such as classification, segmentation and matching. In particular, convolutional neural networks (CNNs) are increasingly used in medical recognition. This study demonstrates usefulness reliability CNNs recognizing side perforation TMs images....
More than half of post-operative complications can be prevented, and operation performances improved based on the feedback gathered from operations or notifications risks during in real time. However, existing surgical analysis methods are limited, because they involve time-consuming processes subjective opinions. Therefore, detection instruments is necessary for (a) conducting objective analyses, (b) providing risk associated with a procedure We propose new real-time algorithm using...
This study aimed to investigate prognostic factors in patients with idiopathic sudden sensorineural hearing loss (ISSNHL).From January 2007 December 2011, a retrospective chart review identified 494 consecutive ISSNHL. Demographic, audiometric, and clinical data were analyzed using logistic regression test.Hearing recovery from ISSNHL was significantly associated such as age, duration onset of symptoms commencement treatment, severity the initial pure tone threshold, treatment method....
This manuscript explores the integration of electronic drawings into surgical operative notes, highlighting their importance in improving quality and utility documentation. Operative as essential components practice, serve various purposes: they detail procedures, provide critical information to healthcare providers, guide treatment planning, function legal records. The transition from traditional hand-drawn illustrations drawings, enabled by growing adoption medical record systems, has...
Coronavirus disease 2019 (COVID-19) changed the practice of medicine, and various anti-contagion restrictions were implemented worldwide. This study aimed to evaluate annual trend in incidence otologic diseases during COVID-19 pandemic determine influence social on these diseases. We retrospectively reviewed number patients treated for diseases, particularly those associated with infectious pathophysiology, total otolaryngology departments at three tertiary referral centers South Korea. The...
Balloon eustachian tuboplasty (BET) is an emerging treatment for dilatory tube (ET) dysfunction. However, its efficacy in patients with both chronic suppurative otitis media (COM) and ET dysfunction remains unclear. The objective of the trial was to assess safety BET versus medical management (MM) alone adult COM dysfunction, which defined by a failed Valsalva maneuver. In this prospective, multicenter, randomized controlled trial, total 116 participants (121 ears) treated between January...
The purpose of this study was to evaluate the efficacy our canalith repositioning procedure (CRP) for benign paroxysmal positional vertigo (BPPV) anterior semicircular canal (ASC). We conducted a prospective 30 ASC BPPV patients analyze modified CRP. When patient diagnosed as having by specific provocative positioning test, CRP performed. response treatment categorized grade I–IV. Of patients, 6 were male and 24 female with highest incidence when in their 50s. nystagmus 29 fully resolved...
Objective To compare pure‐tone audiometry and auditory steady state response (ASSR) to measure hearing loss based on the severity of in frequencies. Study Design Setting A total 105 subjects (168 ears, 64 male 41 female) were enrolled this study. We determined level by measurement ASSR same day for each subject. Results Pure‐tone highly correlated (r = 0.96). The relationship is described equation PTA 1.05 × mean − 7.6. When analyzed according frequencies, correlation coefficients 0.94,...
The Eustachian tube (ET) plays an important role in maintaining a normally aerated middle ear. Inflammation ear disease is related to ET dysfunction, and postoperative restoration of integrity hearing are closely function chronic patients. After successful tympanoplasty, well-aerated with good can permit better compliance the tympanic membrane. In this study, we evaluated predictive validity preoperative measurements.We reviewed 137 patients who underwent type 1 tympanoplasty. All had...
Objectives We investigated changes in video head impulse test (vHIT) gains and corrective saccades (CSs) at the acute follow-up stages of vestibular neuritis to assess diagnostic value vHIT. Study Design Case series with chart review. Setting Tertiary medical center. Subjects Methods Sixty-three patients who underwent vHIT an initial presentation approximately 1-month were included. gains, gain asymmetry (GA), peak velocities CS, interaural difference CS (CSD) analyzed. Results Mean...
Conclusion. Intratympanic dexamethasone (ITD) within 1 month after initial treatment failure should be utilized as salvage for refractory sudden sensorineural hearing loss (SSNHL). Objective. To investigate the therapeutic efficacy over time of ITD in SSNHL. Materials and methods. We retrospectively reviewed medical records audiograms 99 SSNHL patients who were to 2 weeks oral steroid treatment, from August 2003 October 2006. Patients divided into those receiving no further (control group)...
Background: The putative goal of sac surgery in Ménière's syndrome is to promote the flow endolymph from labyrinth endolymphatic and thereby relieving hydrops. There are scant published histopathologic data whether actually accomplishes this goal. Objective: To determine relieves hydrops by examining changes temporal bones obtained individuals who had undergone during life for syndrome. Methods: Temporal were examined 15 patients surgery. Data on presence severity hydrops, histology sac,...
