Abstract
Eustachian tube dysfunction (ETD) is a condition where the Eustachian tube (ET) fails to function normally, resulting in symptoms such as aural fullness, tinnitus, autophony, and hearing loss. ETD can further lead to middle ear diseases such as otitis media effusion and adhesive otitis media, which is becoming more common in the field of otology. Although the pathogenesis of ETD remains unclear, recent animal studies and clinical experiments have found allergic reactions and allergic diseases are closely related to the occurrence of ETD. As the mucosa of the ET is continuous with that of the nasopharynx and tympanic cavity, it is reasonable to assume that the immunological basis of the ET itself is similar to that of respiratory allergic diseases. However, due to the special anatomical location and complex pathogenesis of the ET, there is still no unified diagnostic gold standard. Additionally, there is an ongoing debate regarding whether ETD can be classified as a distinct disease or even an allergic disease. Furthermore, the effectiveness of anti-allergic therapy in patients with ETD is yet to be fully understood. Therefore, this review elaborates on the possible mechanisms of allergic reactions in the occurrence and development of ETD, and explores the potential role of anti-allergic therapy in managing this condition, in order to provide new insights into the pathogenesis and prevention of ETD.

ISOM 2023 Research Panel 5: Interventions- Vaccines and prevention, medical and surgical treatment, and impact of COVID-19 pandemic. Int J Pediatr Otorhinolaryngol 2024; 176:111782. [PMID: 38000342 PMCID: PMC10842145 DOI: 10.1016/j.ijporl.2023.111782] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 10/05/2023] [Accepted: 11/05/2023] [Indexed: 11/26/2023]
Abstract
OBJECTIVES To identify and synthesize key research advances from the literature published between 2019 and 2023 on the advances in preventative measures, and medical and surgical treatment of uncomplicated otitis media (OM) including the impact of the COVID-19 pandemic on OM management. DATA SOURCES Medline (PubMed), Embase, and the Cochrane Library. REVIEW METHODS All relevant original articles published in English between June 2019 and February 2023 were identified. Studies related to guideline adherence, impact of treatment on immune response and/or microbiology, tympanoplasty, Eustachian tube balloon dilatation, mastoidectomy procedures, and those focusing on children with Down's syndrome or cleft palate were excluded. MAIN FINDINGS Of the 9280 unique records screened, 64 were eligible for inclusion; 23 studies related to medical treatment, 20 to vaccines, 13 to surgical treatment, 6 to prevention (excl. vaccines) and 2 to the impact of COVID-19 on OM management. The level of evidence was judged 2 in 11 studies (17.2 %) and 3 or 4 in the remaining 53 studies (82.8 %) mainly due to the observational design, study limitations or low sample sizes. Some important advances in OM management have been made in recent years. Video discharge instructions detailing the identification and management of pain and fever for parents of children with acute otitis media (AOM) was more effective than paper instructions in reducing symptomatology; compared to placebo, levofloxacin solution was more effective for treating chronic suppurative otitis media, whereas AOM recurrences during two years of follow-up did not differ between children with recurrent AOM who received tympanostomy tube (TT) insertion or medical management. Further, novel pneumococcal conjugate vaccines (PCV) schedules for preventing OM in Aboriginal children appeared ineffective, and a protein-based pneumococcal vaccine had no added value over PCV13 for preventing AOM in native American infants. During the COVID-19 pandemic, a decline in OM and TT case volumes and complications was observed. IMPLICATION FOR PRACTICE AND FUTURE RESEARCH Whether the observed impact of the COVID-19 pandemic on OM management extends to the post-pandemic era is uncertain. Furthermore, the impact of the pandemic on the conduct of urgently needed prospective methodologically rigorous interventional studies aimed at improving OM prevention and treatment remains to be elucidated since the current report consisted of studies predominantly conducted in the pre-pandemic era.
