Langerhans cell histiocytosis (LCH) is commonly characterized by abnormal function and differentiation or proliferation of monocytes. In LCH, granulomatous lesions, including langerine-positive histocytes and inflammatory infiltrates, can occur to all tissues, particularly well in the bones, skin, lungs, and pituitary gland. In case of external auditory canal LCH, conductive hearing loss may occur, and the most common symptom is otorrhea. Here we present a case that 49-year-old male with external auditory canal mass. Since no invasive findings were seen in radiologic study, endoscopic transcanal excision was performed and LCH was proven by pathologic report. We present this case of external auditory canal LCH with the review of literature.

Conductive Hearing

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. El tratamiento de la estenosis del conducto auditivo externo (EAC) a menudo requiere del uso prolongado de un stent o una férula. Los stents tradicionales a menudo ocluyen el EAC, provocando una hipoacusia conductiva temporal. Este reporte describe un caso un molde auditivo hecho a la medida con un agujero grande utilizado como stent en un paciente con estenosis del EAC. El stent de molde auditivo a la medida fue exitoso en prevenir la re-estenosis, mientras que el gran agujero aportó ventilación y mejoró subjetivamente la audición durante la fase de mantenimiento del stent.

Conductive Hearing

Cholesteatomas are found almost exclusively in the middle ear and mastoid. Occasionally this disease is seen in the external auditory canal. Cholesteatoma of the external auditory canal is a rare condition. Severe pain and profuse discharge associated with a normal eardrum and normal hearing are essential clinical features. In addition, we found facial paresis and conductive hearing loss in our case. Smaller cholesteatomas can be managed by frequent debridement in the office; larger lesions require surgical intervention. Surgery is successful in resolving otorrhea and relieving pain. In addition, our own experience has shown that surgery is successful in relieving facial paresis.
