The treatment of external auditory canal (EAC) stenoses often requires the prolonged use of a stent or splint. Traditional stents often occlude the EAC, resulting in a temporary conductive hearing loss. This case report describes a custom canal earmold with a large bore used as a stent in a patient with EAC stenosis. The customized earmold stent successfully prevented restenosis, while the large bore provided ventilation and improved hearing subjectively during the stenting phase.
外耳道狭窄的治疗通常需要长期使用支架或夹板。传统支架常常会堵塞外耳道,导致暂时性传导性听力损失。本病例报告描述了一例将定制的大孔径耳道耳模用作外耳道狭窄患者支架的情况。定制的耳模支架成功预防了再狭窄,同时大孔径在支架置入阶段提供了通气功能并主观上改善了听力。
