Objective: The Jahn ventilating tube (JVT) is an osseointegrated middle ear ventilating tube that is used internationally in the treatment of Eustachian tube dysfunction (ETD). Little long‐term data exists quantifying the functions and complications of this device. This study aims to assess the long‐term outcomes with use of the JVT. Method: Retrospective chart review of 22 patients (24 ears) with ETD managed with JVT (1994‐2008) with at least 3 years of follow‐up, or documented JVT failure at any time point. Main outcome measures were duration of patency, time to extrusion, middle ear aeration, audiogram, Sade score, and complication rate. Results: Twelve out of 24 JVTs were patent at last follow‐up. Mean duration of retention of a patent tube was 6 years. Aeration of the middle ear with a patent JVT was excellent, with mean Sade score at last visit of 1.08. Mean improvement in air bone gap between the preoperative and last visit was 3 dB. Twelve out of 24 JVTs extruded during the study period. The mean time to extrusion was 21 months. There was no difference in age at insertion between the 2 groups (P =. 113). Two complications were identified, which were persistent tympanic membrane perforations. Conclusion: JVTs are a safe alternative to traditional pressure equalization tubes. When successful, they can establish a well‐aerated middle ear for extended periods of time. However, early extrusion undermines reliability. [ABSTRACT FROM AUTHOR] |
