BONE CONDUCTION HEARING IMPLANT: INDICATIONS, OUTCOMES, COMPLICATIONS, AND MANAGEMENT – A LITERATURE REVIEW
Nội dung chính của bài viết
Tóm tắt
Background: Bone conduction hearing implants (BCHI) have become an important solution for patients with conductive, mixed hearing loss, or single-sided deafness who are unsuitable for conventional air-conduction hearing aids. Recent technological advances, including percutaneous and transcutaneous active systems, have improved auditory outcomes while reducing soft-tissue complications.
Objective: To synthesize current evidence on indications, auditory outcomes, complications, and management strategies of BCHI over the past five years.
Methods: A descriptive review was conducted using PubMed, Scopus, Cochrane Library, Google Scholar, and relevant Vietnamese ENT journals. Studies published between 2019 and 2024 reporting indications, clinical outcomes, complications, or management of BCHI were included. Data were extracted independently by two researchers and summarized into four categories: indications, auditory outcomes, complications, and management of complications.
Results: Analysis of recent literature shows that BCHI is highly effective in improving functional hearing thresholds and speech understanding, particularly in patients with conductive/mixed hearing loss and single-sided deafness. The most common complications involve soft-tissue reactions, including skin irritation, peri-implant granulation, and minor infections, with lower rates in transcutaneous active systems (e.g., Osia®, Bonebridge) compared to percutaneous devices. Management strategies include conservative care (hygiene, topical antibiotics/steroids, adjustment of magnet force) and surgical interventions in severe or recurrent cases. Early selection of suitable candidates and careful surgical technique are critical to minimizing complications and optimizing outcomes.
Conclusion: BCHI provides a safe and effective method for hearing rehabilitation, with a favorable complication profile, particularly for transcutaneous active systems. Proper patient selection, standardized surgical procedures, and evidence-based management of complications are essential for maximizing functional gains and patient satisfaction.
