Controlled Clinical Trial on Bone-anchored Hearing Implants and a Surgical Technique With Soft-tissue Preservation

Abstract

Tissue preservation compared with tissue reduction leads to a generally favorable clinical outcome, comparable audiology results, and significantly shorter surgery time. Longer follow-up is warranted to conclude on the increased adverse soft-tissue reactions after 6 months.

Short‐term results from seventy‐six patients receiving a bone‐anchored hearing implant installed with a novel minimally invasive surgery technique

“…12 Overall, the medium-to-long-term results of tissue preservation surgery are promising with skin reactions at least similar to control groups, and benefits including less numbness and more cosmetically pleasing outcomes being commonly reported. 1,3,9,10 This multicentre evaluation reported here demonstrates, short-term, similar positive outcomes for MIPS.…”

“…1,3,8 Due to instrumentation and pre-defined steps, MIPS requires short surgical time, and naturally lends itself to be performed under local anaesthesia. This technique is conducive to fast healing due to minimal soft tissue trauma.…”

“…Nevertheless, the outcomes regarding sensibility were good with few reports of numbness and pain, comparable with short-term data reported previously. 3,[8][9][10] Moreover, no sutures are required and the early cosmetic outcome is promising.…”

“…[1][2][3] Some surgeons are also performing the surgery and installation, using the classical drilling system, through a single punch entry. [4][5][6] The minimally invasive Ponto surgery (MIPS) was suggested as a refinement of the tissue preservation techniques.…”

“…The Holgers index is routinely used as one of the major endpoints in BAHS studies 5, 30. It captures external signs of inflammation, such as moistness or redness.…”
