RESUMO
BACKGROUND: Stapedotomy is a common treatment for conductive hearing loss in otosclerosis patients. AIMS/OBJECTIVES: Results of stapedotomy were assessed in terms of hearing improvement and risk of complications. Potential prognostic factors affecting outcomes were identified. MATERIAL AND METHODS: Retrospectively, 93 stapedotomies were evaluated. The primary outcome was hearing improvement based on postoperative ABG ≤10 dB, Belfast rule of thumb, and AC gain ≥20 dB. Secondary outcomes were postoperative complications. Additionally, prognostic factors potentially affecting outcomes were analyzed (age, gender, comorbidity, preoperative audiometry, tinnitus, or vertigo). RESULTS: A mean ABG of ≤10 dB was achieved in 59%. According to the Belfast rule of thumb, 75% achieved interaural symmetry within ≤15 dB and/or a mean AC4 of ≤30 dB. A gain in AC4 of ≥20 dB was achieved in 57% of primary surgeries. The larger the preoperative ABG, the better hearing after surgery. There was no significant difference in hearing improvement at early and late follow-ups. Transient vertigo was the most common complaint (37%). Taste disturbances were the most frequent permanent complication (14%). CONCLUSION AND SIGNIFICANCE: Stapedotomy gave good audible improvement with a low risk of complications. Preoperative ABG was the only prognostic factor affecting the hearing outcome. Only one follow-up 6-12 months seems relevant.

There is no unanimous consensus for indications of eustachian tube balloon dilation (ETBD). Nordic countries have relatively similar hospital organizations and treatment guidelines. Therefore, it was logical to organize a consensus meeting of ETBD. The symposium: Nordic Experiences on Eustachian Tube Balloon Dilation, in Copenhagen, 30-31 March, 2017. The panellists from Denmark, Finland, Norway and Sweden and the attendees of the meeting agreed a consensus on the following issues: Candidates, Definition of Eustachian Tube Dysfunction, Diagnostic Work up, Differential Diagnosis, Contraindications, ETBD Procedure, Complications, Follow-up, and Outcomes. The article also presents the status for ETBD in each of these countries. Thereafter the consensus statement has been discussed in the national societies and meetings for ear surgeons in each of these countries. It can be assumed that surgeons in the hospitals of these Nordic countries generally follow the recommendations from the consensus meeting.
