“…While using the ultrasonic serrated knife, we protected the EAC skin with the use of foil, similar to what has been described in other series where drilling is performed. 19,22,23 Overall, all of the patients in our series demonstrated well healed EACs postoperatively with the transcanal use of Sonopet with an average healing time of 3.3 weeks.…”

Objective To describe a novel approach for excision of exostoses and evaluate the outcomes of transcanal excision of exostoses using ultrasonic serrated knife-assistance vs. micro-osteotomes only. Study Design Retrospective analysis Setting Academic Tertiary Care Center Patients/Interventions Patients receiving a transcanal excision of exostoses between 2007 and 2016. Main outcome measures The outcomes and post-operative complications of 138 patients who received transcanal micro-osteotome only technique were compared to 10 patients who received transcanal excision of exostoses using ultrasonic serrated knife-assistance (Stryker Corporation, Kalamazoo, MI). Results A total of 175 ears in 128 patients underwent a transcanal micro-osteotome only technique. Of these, 11 (6.3%) developed an intra-operative tympanic membrane perforation. One developed anterior canal mobilization requiring prolonged (3 weeks) packing. One hundred and thirty five ears (77%) were well healed by the three week post-operative visit. All but one ear was well healed by the six week visit. In comparison, 11 ears in 10 patients were treated for exostoses using a transcanal approach with the use of ultrasonic serrated knife and micro-osteotomes. One ear canal (the first in the series) was not well healed by the three week post-operative visit due to suspected thermal injury. All patients had well healed ear canals by six weeks, and there were no complications. Conclusions This is the first series to report the use of an ultrasonic serrated knife in the transcanal excision of exostoses. When compared to a transcanal micro-osteotome only excision of exostoses, the addition of the Sonopet appears to result in a similarly low complication rate. Sonopet can allow for more controlled transcanal excision of broad based exostoses in patients with severe obstruction.

“…The anterior canal skin flap is sutured to the lateral skin to achieve more secure coverage of the underlying bone. 4,8 Additionally, we have been able to avoid restenosis and the need for revision surgery of any kind in all cases within our follow-up period. 4,9 Our use of temporoparietal fascia grafting in these instances provides comparable soft tissue coverage while avoiding potential morbidity at the skin graft harvest site, and is believed to facilitate the regrowth of native ear canal skin.…”

“…Thus, a huge variety of flaps has been reported: superiorly based preauricular 22 or conchal bowl; 23 posteriorly based; 24 both anteriorly and posteriorly based; 25 superiorly based conchal skin; 26 inferiorly based posterior meatal; 27 and flaps based on the middle temporal artery. 28 Others have suggested preservation of a skin bridge in the canal to promote healing by epithelial migration. 29,30 Allowing the canal to heal by secondary intention 31 is no longer considered acceptable in terms of patient morbidity and long-term results.…”
