Article Synopsis
  • The pilot study evaluated how effective portable otoendoscopes are for at-home ear examinations during the COVID-19 pandemic and whether training improves image quality.
  • After participants received training, otolaryngologists found that more of the tympanic membrane was visible in the images, boosting their confidence in diagnosing ear conditions, but most still preferred in-person exams.
  • Participants found the otoendoscope easy to use and were willing to pay for it, although the images alone were generally insufficient for a definitive diagnosis.

SARS-CoV-2, the novel coronavirus resulting in the present COVID-19 pandemic, has increased the otolaryngologist's reliance on telemedicine to manage outpatient pathology. The nature of telemedicine, however, limits a provider's ability to obtain a comprehensive physical examination, specifically of the tympanic membrane. Various smartphone-based otoscopic attachments are now available that facilitate patient-obtained otoscopic image capture of the tympanic membrane.

Poor language development in patients with sensorineural hearing loss (SNHL) may be related to an auditory deficit and/or other neurologic condition that influences the ability to communicate. A retrospective chart review of children (mean age = 4.0 years) with congenital, bilateral SNHL was performed to assess for linguistic and nonlinguistic neurodevelopmental differences between those who were language-impaired (LI) versus non-language-impaired (NLI).

Clinical registries have proven beneficial by providing a resource to address research questions, monitor care, and identify suitable subjects for clinical studies. Despite a well-organized registry, population is often low because of the human capital required. The increasing prevalence of electronic medical health records provides the opportunity to integrate registry compilation into routine patient encounters.

Objectives: This was a pilot study to establish a protein difference between thyroglossal duct cyst fluid relative to oral saliva, in order to differentiate patients with residual thyroglossal cyst from those with salivary fistula in the case of post-Sistrunk procedure incisional drainage. Past immunohistochemistry studies on archived tissue blocks from post-Sistrunk procedure patients have shown MUC5AC to have elevated concentrations in thyroglossal duct relative to salivary tissue; secretory immunoglobulin A (IgA) was also chosen as a candidate protein based on previously published reports of its increased concentration in saliva relative to respiratory secretions.

Design: Diagnostic tests were assessed.

Development of the craniofacial and upper airway structures is a complex choreography of mesenchymal and epithelial tissues responding to soluble growth factors and transcription factors in a tightly regulated sequence. Interruption of the development process or mutation of required transcription or growth factors leads to congenital anomalies of the facial and airway structures. Oftentimes, these patients suffer life-long consequences, require multiple medical and surgical interventions, and have significant associated morbidity and mortality.

Objective: Luminal expansion of the cricoid cartilage appears to be stunted by loss of luminal epithelium (LE) and can be enhanced by transforming growth factor-beta3 (TGF-beta3). When both the LE and perichondrium are disrupted, matrix metalloproteinase (MMP) levels within adjacent chondrocytes are diminished but can be restored by exogenous TGF-beta3. Cricoid growth stunting and luminal expansion that occur in the absence and presence of MMP activity, respectively, suggest that MMPs play an important role in normal subglottal development.

The upper airway serves three important functions: respiration, swallowing, and speech. During development it undergoes significant structural and functional changes that affect its size, shape, and mechanical properties. Abnormalities of the upper airway require prompt attention, because these often alter ventilatory patterns and gas exchange, particularly during sleep when upper airway motor tone and ventilatory drive are diminished.

Objectives: We performed a pilot study to determine whether there is an age-related change in inflammatory expression in the subglottic mucosa of rabbits in response to a one-time injury.

Methods: Twenty-seven rabbits of 3 different ages meant to represent infant, adolescent, and adult stages underwent a unilateral, subglottic soft tissue injury. The animal groups were allowed to heal for 3 different durations to reflect the early, middle, and late stages of inflammation.

Objectives: We determined the location of matrix metalloproteinases (MMP) 2 and 9, and whether the luminal perichondrium or transforming growth factor (TGF) beta3 influences the presence of MMP-2 and/or -9 within the chondrocytes of the cricoid cartilage.

Methods: Subglottises from 15 neonatal mice were divided into group A (N = 5; luminal epithelium intact, grown in basic medium), group B (N = 5; epithelium-free, with sections of luminal perichondrium removed, grown in basic medium), and group C (N = 5; epithelium-free, with sections of luminal perichondrium removed, grown in basic medium with supplemental TGF-beta3). Immunohistochemical analysis was done to identify MMP-2 and -9 distributions.
