“…Subjective tinnitus refers to a phantom perception, whereas objective tinnitus refers to perceived sounds generated from an acoustic source located within the body. Pathologies causing objective tinnitus are rather heterogeneous and research to understand and treat this form of tinnitus is ongoing (Liu et al, 2019;Choi et al, 2020). It is, however, far less common than subjective tinnitus and its underlying mechanisms are usually clearer (Tunkel et al, 2014).…”

Tinnitus can be a burdensome condition on both individual and societal levels. Many aspects of this condition remain elusive, including its underlying mechanisms, ultimately hindering the development of a cure. Interdisciplinary approaches are required to overcome long-established research challenges. This review summarizes current knowledge in various tinnitus-relevant research fields including tinnitus generating mechanisms, heterogeneity, epidemiology, assessment, and treatment development, in an effort to highlight the main challenges and provide suggestions for future research to overcome them. Four common themes across different areas were identified as future research direction: (1) Further establishment of multicenter and multidisciplinary collaborations; (2) Systematic reviews and syntheses of existing knowledge; (3) Standardization of research methods including tinnitus assessment, data acquisition, and data analysis protocols; (4) The design of studies with large sample sizes and the creation of large tinnitus-specific databases that would allow in-depth exploration of tinnitus heterogeneity.

“…Although there is a paucity of data in the natural history of asymptomatic persistent FH, the authors do not feel that observation in asymptomatic patients would increase the risk of complications in the future. 5,6,[8][9][10]13,15,17 Further work is warranted to better understand both the natural history of this pathology as well as the prevalence of symptomatic disease among patients with radiographically confirmed dehiscences.…”

“…Although incidental persistent FH is diagnosed in 11.5%-20% of individuals undergoing temporal bone imaging, few studies have described the clinical nature of this pathology. [2][3][4] Available literature reports on single cases [5][6][7][8][9][10][11][12][13][14] or small case series 15,16 that highlight the presentation and management variability associated with this pathology. Understanding of this pathology from the lone review examining temporomandibular joint herniation into the EAC is limited given the wide variance in literature and the presentation of all EAC fistula patients, including spontaneous and non-spontaneous fistulae, as a single group in this study; therefore, conclusions are restricted when looking specifically at persistent FH.…”

Objective: Describe the presentation and management strategy for patients with symptomatic foramen of Huschke (FH).Patients: Adults with persistent FH confirmed on imaging.Interventions: Diagnosis and management of symptomatic persistent FH.Main outcome measure: Resolution of otologic symptoms.Results: A total of four patients with symptomatic, radiographically-confirmed persistent FH were included. The majority of patients endorsed otalgia (n = 4) and otorrhea (n = 3), and only one patient was noted to have a conductive hearing loss. All patients were noted to have dynamic movement of an external auditory canal mass with mandible manipulation on examination, and all patients had an identifiable fistula on imaging. Patients underwent surgical intervention, including both preauricular (n = 2) and transcanal (n = 2) approaches, and all endorsed symptomatic resolution after convalescence.Conclusions: Persistent FH remains an uncommon and potentially underrecognized cause of otologic symptoms. Diagnosis requires a high index of suspicion, and one must rely on both key examination findings and imaging to confirm this diagnosis. In appropriately selected patients, surgical intervention can provide durable symptomatic resolution.

“…Choi et al and Lim et al reported cases of clicking tinnitus with clenching teeth, while there was no history of trauma or surgery in the TMJ region. The CT scan of the temporal bone indicated a bony defect in the posteromedial wall of glenoid fossa, and the otoscopic examination indicated TMJ herniation through FH into EAC [ 28 , 36 ].…”

Background Foramen of Huschke has been presented as an unusual developmental defect in anteroinferior aspect of external auditory canal. It can be associated with significant otologic complications. The purpose of this study was to determine the association between existence of foramen of Huschke and temporomandibular joint disorders in Cone Beam Computed Tomography (CBCT) images. Methods Of an initial sample of 465 patients, we retrospectively evaluated the CBCT images of 118 individuals with clinical signs and symptoms of temporomandibular joint disorders as case group and 256 individuals as control group. The presence, size and localization of foramen of Huschke were assessed in the axial and corrected sagittal images. The sex and age distribution were determined. Fisher’s exact test, T-test and Pearson’s Chi-square were applied to assess the relationship between foramen of Huschke and temporomandibular joint disorders in the case and control groups considering age and sex. Results The foramen of Huschke prevalence was slightly higher in patients with temporomandibular joint disorders (3.4%) than patients without temporomandibular joint disorders (0.8%). However, the difference was not statistically significant (P = 0.082). foramen of Huschke was found in five females and one male. There was no significant difference between case and control groups considering the age of patients with foramen of Huschke (P = 0.683). There was no significant difference between the case and control groups, considering the right and left ears in distribution of foramen of Huschke (P = 0.099) (P = 0.183). Conclusions Higher prevalence of foramen of Huschke in patients with temporomandibular joint disorders may suggest possible mechanism for temporomandibular joint disorders development that can be affected by presence of foramen of Huschke.
