Abstract

Background: Percutaneous bone anchored hearing systems have been used effectively for over forty years with low rates of complications. Minimally Invasive Ponto Surgery (MIPS) is a surgical technique performed through a puncture hole that has been reported to minimize soft tissue trauma and decrease operative time. Due to it being a relatively new procedure there remains a paucity of pediatric outcomes data. Methods: Pediatric patients from two tertiary pediatric otolaryngology centers between 2016 and 2019 who underwent MIPS were included in this study. Charts were retrospectively reviewed for indications for surgery, implant and abutment type, overlying skin thickness, skin-to-skin time, Holgers score at three, six and twelve months, revision surgery and time to abutment fitting. Results: Fourteen patients, two with bilateral procedures met inclusion criteria (mean age = 8.07 ± 2.87years). The mean overlying skin thickness was 5.13 ± 3.18mm. 9.44% of visits had an adverse skin reactionOne patient required surgery forskin overgrowth. One implant loss (6.3%) was reported, following trauma to the abutment. Mean MIPS skin to skin times were 12.4 ± 2.6 min, markedly different that the Baha® Attract and Connect which were 56 and 53 min, respectively. Conclusion: This study represents the largest pediatric MIPS cohort to date, and our results are similar to published adult studies.
