Perforation of the tympanic membrane (TM) is a common condition that often requires a scaffold as a support for surgery. However, because of the external environment of the auditory canal, the scaffold could become bacterially infected and prevent the TM from healing. As a result, the perfect scaffold should have both antibacterial and biomimetic qualities. In this study, the biodegradable biomaterial poly(1,4-butylene carbonate) (PBC) films containing levofloxacin (LEV) was successfully prepared for the first time. The results showed that the hydrophilicity of the LEV/PBC film was improved after the addition of LEV, and the tensile strength was also complied with the requirements of the standard. The created antibacterial film demonstrated excellent antibacterial properties. In vitro hemolysis experiments revealed no risk of hemolysis for the new material, and the cytotoxicity study further confirmed its non-cytotoxic nature. Overall, LEV was a good component of PBC/LEV film, which is expected to be used for TM repair in the future.

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.

Objective: Chronic otitis media (COM) is characterized by chronic, intermittent, or persistent discharge through a perforated tympanic membrane. In this study, we aimed to evaluate the postoperative audiological outcomes in middle-aged patients compared to younger patients who underwent tympanoplasty with mastoidectomy via post-auricular approach for the treatment of COM.
Methods: This prospective interventional study included patients admitted in wards from August 2017 to January 2019 at the Department of Otorhinolaryngology, Jawaharlal Nehru Medical College and Hospital, Aligarh, India.

Background: To prospectively determine whether tympanoplasty for tympanic membrane perforation (TMP) in wet ears impacts recovery.
Methods: We prospectively enrolled 32 TMP patients (2021-2023) and divided them into the wet-ear (14 patients) and dry-ear groups (18 patients), according to the presence of middle-ear secretions/edema. All patients underwent high-resolution thin-slice computed tomography, ear endoscopy, and pure tone audiometry.

Objectives: To assess the prevalence and associated factors of hearing loss in Ethiopia, considering socioeconomic conditions, regional variations and age-related impacts.
Design: Nationwide cross-sectional survey.
Setting: Data were collected from 2 February to 10 June 2023, covering all regions of Ethiopia except Tigray (due to security concerns).
