“…12,16 The use of video-pneumatic otoscopy may address the difficulty in identifying a retracted tympanic membrane while being appropriate for use within a hearing telehealth clinic. 26,27 Using video-pneumatic otoscopy and quantitative analysis of the degree of movement of the umbo of the malleus, Cho et al 27 reported correlation between tympanograms and, among other middle ear pathologies, negative middle ear pressure. Although otitis media with effusion may occur spontaneously because of negative middle ear pressure, 28 the identification of a retracted tympanic membrane may not be highly significant within a primary healthcare environment in a rural or underserved area.…”

Objective: The study investigated whether video-otoscopic images taken by a telehealth clinic facilitator are sufficient for accurate asynchronous diagnosis by an otolaryngologist within a heterogeneous population. Subjects and Methods: A within-subject comparative design was used with 61 adults recruited from patients of a primary healthcare clinic. The telehealth clinic facilitator had no formal healthcare training. On-site otoscopic examination performed by the otolaryngologist was considered the gold standard diagnosis. A single video-otoscopic image was recorded by the otolaryngologist and facilitator from each ear, and the images were uploaded to a secure server. Images were assigned random numbers by another investigator, and 6 weeks later the otolaryngologist accessed the server, rated each image, and made a diagnosis without participant demographic or medical history. Results: A greater percentage of images acquired by the otolaryngologist (83.6%) were graded as acceptable and excellent, compared with images recorded by the facilitator (75.4%). Diagnosis could not be made from 10.0% of the video-otoscopic images recorded by the facilitator compared with 4.2% taken by the otolaryngologist. A moderate concordance was measured between asynchronous diagnosis made from videootoscopic images acquired by the otolaryngologist and facilitator (j = 0.596). The sensitivity for video-otoscopic images acquired by the otolaryngologist and the facilitator was 0.80 and 0.91, respectively. Specificity for images acquired by the otolaryngologist and the facilitator was 0.85 and 0.89, respectively, with a diagnostic odds ratio of 41.0 using images acquired by the otolaryngologist and 46.0 using images acquired by the facilitator. Conclusions: A trained telehealth facilitator can provide a platform for asynchronous diagnosis of otological status using video-otoscopy in underserved primary healthcare settings.

“…Among patients with CHL, the differential diagnosis in cases with intact tympanic membrane (TM) can be challenging to clinicians, as no absolute diagnostic test is available for these patients [1,2]. To improve the preoperative diagnosis in CHL cases with intact TM, a variety of approaches have been evaluated, such as multi-frequency tympanometry [3], sweep frequency tympanometry [4], the liquid and acoustic reflex test [5], and pneumatic otoscopy [6]. Several approaches have revealed positive results in predicting the diagnosis of CHL; however, the results have been unsatisfactory for application to clinical practice.…”

“…In this study, the pneumatic‐induced motions of the human TM were quantitatively assessed in vivo using a custom‐developed OCT system that resembles a pneumatic otoscope, the guideline recommended diagnostic tool for OM. Previous efforts to quantify the pneumatic movements of the TM involved tracking the positions of the TM structures (the umbo and the handle of malleus) during video pneumatic otoscopy [30, 31] and estimating the movements in pixels during video pneumatic otoscopy combined with a motion magnification algorithm [32]. However, quantification of standard pneumatic otoscopy still suffers from insufficient information about the axial movements and the structural variability of the human TM.…”

Decreased mobility of the human eardrum, the tympanic membrane (TM), is an essential indicator of a prevalent middle ear infection. The current diagnostic method to assess TM mobility is via pneumatic otoscopy, which provides subjective and qualitative information of subtle motion. In this study, a handheld spectral‐domain pneumatic optical coherence tomography system was developed to simultaneously measure the displacement of the TM, air pressure inputs applied to a sealed ear canal, and to perform digital pneumatic otoscopy. A novel approach based on quantitative parameters is presented to characterize spatial and temporal variations of the dynamic TM motion. Furthermore, the TM motions of normal middle ears are compared with those of ears with middle ear infections. The capability of noninvasively measuring the rapid motion of the TM is beneficial to understand the complex dynamics of the human TM, and can ultimately lead to improved diagnosis and management of middle ear infections.
