Objectives. Clinical presentation is critical to identify suspected perilymphatic fistula (PLF). To explain characteristic of PLF, it was hypothesized that a third window lesion might be involved in the pathomechanism. The purpose of this study is to investigate clinical features in PLF and figure out the relationship of third window effect and PLF. Methods. Sixty patients underwent surgical exploration under suspicion of PLF and reinforecmenet of oval window and round window was performed. Clinical features including demographics, pure tone audiometry (PTA), and videonystagmography (VNG) were evaluated preoperatively and 1 month after operation. Surgical outcomes were analyzed according to the improvement of hearing and vestibular symptoms and signs. The conductive components of PTA (air-bone gap (ABG)) were measured, and the relationship between ABG closure after surgery and hearing improvement was analyzed. In addition, the postoperative subjective dizziness was assessed by interview in clinic. The change of positional nystagmus was analyzed according to ABG closure and hearing improvement.Results. ABG at lower frequencies (LFABG, 250 Hz, 500 Hz, 1,000 Hz) was present in 27 patients (45%). Postoperatively, the PTA was significantly improved after surgical repair. Among the patients with preoperative LFABG (n=27), 15 (55.5%) showed postoperative ABG closure and significant improvement in PTA at all frequencies compared with the patients without ABG closure (P=0.012). The subjective dizziness improved in 56 patients (91.8%). Positional nystagmus was found in 45 of 49 patients. Multiple canal involvement was more common than single canal (67% vs. 33%). The horizontal semicircular canal was most commonly involved, followed by the posterior and anterior canals. Postoperatively, the positional nystagmus disappeared, or the number of involved canals decreased in 22 of 34 (64.7%) patients. Conclusions. Pseudo-conductive hearing loss at the lower frequencies and positional nystagmus originating from multiple semicircular canals were common findings in PLF. Surgical reinforcement of the RW and OW improved hearing threshold accompanied by closure of ABG. The third window lesion might explain these clinical features that indicate PLF.

Background: Otomycosis affects about 9% of patients with otitis externa. One of the predisposing factor is impacted cerumen.  Earphone usage causes cerumen impaction. In the light of the recent COVID-19 pandemic, people are housebound due to prolonged lockdown. Hence people are more technology dependent as working from home and studying online has become the norm. Therefore, usage of earphones has proportionately increased, and the impacted cerumen cases have increased. Methods: This cross-sectional study aimed to analyze data from questionnaire to assess the prevalence of otomycosis among patients with impacted cerumen due to excessive earphone usage, establish associations between otomycosis and symptoms such as pain and hearing loss as well as the correlation between fungal growth and the long hours of earphones usage. The relationship between the age of participants and the usage of earphones during the pandemic was also explored. The data was collected from 100 individuals aged 14 to 51 years who sought treatment for symptomatic impacted wax at an ENT clinic in Malaysia. Results: The mean age of participants was 25.9 years. There was a 31% prevalence of otomycosis among these patients. Otalgia was present in 60% of patients with otomycosis (t value 2.94, coefficient 0.27). Approximately 37% of patients had a large air-bone gap indicating conductive hearing loss. There was an insignificant correlation between otomycosis and the longer hours of earphones usage (t value 1.51, coefficient 0.00015). No correlation was found between age of participants and the total hours of earphone usage (t value 0.63, coefficient 0.0012). Conclusion: This study offers initial evidence that earphone usage could be a predisposing factor in developing otomycosis. However, there was no evidence of longer hours of earphones usage increasing the chances of developing otomycosis. Additionally, symptoms like otalgia and conductive hearing loss could be present in both earwax impaction and otomycosis.

The goal of this temporal bone study was to quantify the relationship between specific histologic changes at the stapes footplate and the magnitude of the air-bone gap in otosclerosis. The study material comprised 26 specimens with otosclerosis and 37 age-matched controls. Detailed anatomic measurements were made on each histologic section through the stapes footplate in each bone, resulting in 30 different measurement parameters for each bone. For frequencies 250 to 2,000 Hz, the conductive hearing loss correlated highly with (p <.01) and appeared to be caused primarily by narrowing and loss of the annular ligament, especially at the posterior stapediovestibular joint space. The size of the air-bone gap appeared to be determined by the extent and degree of this pathologic change. Schuknecht's hypothesis that bony ankylosis of the footplate would be associated with an air-bone gap of >30 dB was supported by our data. However, the degree and extent of bony footplate ankylosis could not be reliably predicted by the size of the air-bone gap.

AbstractObjective:To evaluate the relationship between conductive hearing loss and maxillary constriction.Method:A total of 120 people, aged from 7 to 40 years, who were referred to an audiologist when taking out health insurance or for school pre-registration check-up, were selected for this study. A total of 60 participants who had hearing threshold levels greater than 15 dB in both ears were chosen as the conductive hearing loss group. The remaining 60, with normal hearing thresholds of less than 15 dB, were used as the control group. All participants were referred to an orthodontic clinic. Participants who had a posterior crossbite and high palatal vault were considered to suffer from maxillary constriction.Results:There were no significant differences between the sex ratios and mean ages of the groups. However, participants with conductive hearing loss were 3.5 times more likely than controls to suffer from maxillary constriction.Conclusion:Patients who suffer from conductive hearing loss are likely to show a maxillary abnormality when examined by an orthodontist.

Background: Osteogenesis imperfecta (OI) is an inherited bone and connective tissue disorder associated with the lifelong occurrence of frequent fractures following even mild trauma. Hearing loss is frequently reported in patients with OI. Purpose: This investigation is a retrospective study of measurements of tympanometry, acoustic reflexes, and transient evoked otoacoustic emissions in a sample of patients with OI grouped according to age. The purpose of the study was to examine the relationship between the type of OI, age, and audiological findings in a sample of individuals with OI. Research Design: The study examined the correlation between audiometric measures, hearing loss of all types, and type of OI. Study Sample: Forty-one patients with OI were included in the study. The patients were divided into two groups for analysis: one group less than 20 years of age (n = 21) and the other group aged 20 and over (n = 20). Results: Hearing loss of all etiologies was observed in 62% of ears. Sensorineural or mixed hearing loss was observed in 41% and conductive hearing loss in 21% of ears. Results indicate that the younger patients with OI were subject to a greater risk of middle ear dysfunction associated with otitis media than is typical for children of comparable age. Tympanometric abnormalities associated with ossicular dysfunction were more often found in the older age group of patients. Hearing loss of all types was more prevalent in the older group of patients (88%) than in the younger patient group (38%). Conclusions: Hearing loss was not uncommon regardless of age. Therefore, close audiological monitoring of patients with OI is recommended across the age spectrum.
