Congenital aural stenosis surgery offers a reliable path to long-term hearing restoration for patients with narrowed ear canals. Recent clinical findings underscore the effectiveness of the endaural approach combined with canaloplasty and tympanoplasty. This surgical strategy aims to widen the ear canal and improve conductive hearing. Researchers recently evaluated these outcomes over a decade-long period. Their results provide valuable insights into the stability of hearing gains and potential risks of deterioration.
The retrospective cohort study included 77 patients who underwent modified meatoplasty between 2014 and 2025. Initially, these patients presented with a significant mean air-bone gap (ABG) of 52.1 dB. Following the intervention, the average improvement reached 23.8 dB. Most importantly, nearly 67% of patients achieved an ABG of 30 dB or less within the first year. These statistics highlight the immediate functional benefits of congenital aural stenosis surgery. Furthermore, adjusted analysis showed that these improvements remained stable across various follow-up intervals, spanning up to 60 months.
While most patients experience lasting benefits, some may face hearing deterioration. Notably, the study found that such changes typically occur within the first postoperative year. After this period, audiological thresholds generally stabilize. Researchers identified the preoperative air-conduction (AC) threshold as a critical predictor for this risk. Patients with an initial AC threshold higher than 61.7 dB HL showed a significantly greater likelihood of hearing loss after surgery. Therefore, clinicians should use these preoperative metrics to identify high-risk individuals. Consequently, personalized follow-up schedules during the first year can help manage these patients more effectively.
Yes, most patients maintain their hearing gains for five years or more. While minor fluctuations can occur, long-term audiological outcomes remain significantly better than preoperative levels.
The risk of hearing deterioration is mostly confined to the first postoperative year. If hearing remains stable during these twelve months, long-term stability is highly likely.
Doctors use preoperative air-conduction (AC) thresholds as a primary indicator. Patients with an initial AC threshold exceeding 61.7 dB HL typically face a higher risk and require closer monitoring.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
