Abstract:
The term fibro-osseous lesion encompasses a spectrum of disorders ranging from inflammatory
to neoplastic that microscopically exhibit a connective tissue matrix containing formless
trabeculae of compact bone. Characteristically, they are located over healthy bone, from which
they are abruptly differentiated. The majority of the lesions arise from the maxillofacial
region; the occurrence of a lesion in the external auditory canal (EAC) being extremely rare as is
in our case. The lesions present with a range of symptoms ranging from conductive hearing
loss, Eustachian tube obstruction to bone erosion that develop due to the mass effect. We
report a case of a 35-year-old male patient who presented with insidious onset left aural
fullness, decreased hearing followed by intermittent mucopurulent discharge from the ear, who
was eventually diagnosed with a benign fibro-osseous lesion of the external auditory canal.
