Outcomes of Tympanic Membrane Regenerative Surgery Using Gelatin Sponge, Recombinant Basic Fibroblast Growth Factor, and Fibrin Glue.

Objective We evaluated the outcomes of tympanic membrane regenerative treatment using gelatin sponge, recombinant basic fibroblast growth factor (bFGF), and fibrin glue at Yokosuka Kyosai Hospital. Methodology We enrolled a total of 42 patients with tympanic membrane perforations (TMPs) (44 ears; right:left = 21:23) that were treated using gelatin sponge, recombinant bFGF, and fibrin glue between July 2020 and December 2023 at Yokosuka Kyosai Hospital. TMP closure rates, improvement of hearing level, and complications were retrospectively included in the evaluation items.

Identification of immune-related candidate biomarkers in plasma of patients with sporadic vestibular schwannoma.

Vestibular schwannoma (VS) is an intracranial tumor arising from neoplastic Schwann cells and typically presenting with hearing loss. The traditional belief that hearing deficit is caused by physical expansion of the VS, compressing the auditory nerve, does not explain the common clinical finding that patients with small tumors can have profound hearing loss, suggesting that tumor-secreted factors could influence hearing ability in VS patients. We conducted profiling of patients' plasma for 66 immune-related factors in patients with sporadic VS ( > 170) and identified and validated candidate biomarkers associated with tumor size (S100B) and hearing (MCP-3).

Pediatric internal auditory canal cavernous hemangioma with rapid progression of sensorineural hearing loss: illustrative case.

Background: Cavernous hemangioma of the internal auditory canal is extremely rare and is characterized by symptoms such as vertigo, sensorineural hearing loss, and facial nerve dysfunction.

Observations: A health examination on an 11-year-old female in the fifth grade revealed hearing loss in the left ear. She also had dizziness that had persisted for approximately 1 year.

Identification of Immune-Related Candidate Biomarkers in Plasma of Patients with Sporadic Vestibular Schwannoma: Candidate Plasma Biomarkers in Vestibular Schwannoma.

Vestibular schwannoma (VS) is intracranial tumor arising from neoplastic Schwann cells, causing hearing loss in about 95% of patients. The traditional belief that hearing deficit is caused by physical expansion of the VS, compressing the auditory nerve, does not explain the common clinical finding that patients with small tumors can have profound hearing loss, suggesting that tumor-secreted factors could influence hearing ability in VS patients. Here, we conducted profiling of patients' plasma for 67 immune-related factors on a large cohort of VS patients (N>120) and identified candidate biomarkers associated with tumor growth (IL-16 and S100B) and hearing (MDC).

Petrous internal carotid artery aneurysm rupture induced by Eustachian tube catheterisation: case report.

Background: Petrous internal carotid artery aneurysms are very rare vascular lesions, which may present with otalgia and life-threatening massive otorrhoea.

Case Report: An 84-year-old woman presented at a local otolaryngology clinic with progressive otalgia due to an acute exacerbation of chronic otitis media. She was referred with left-sided massive otorrhoea following Eustachian tube catheterisation.
