EAC osteomas are rare, benign, unilateral, solitary tumour, which are slow growing. usually asymptomatic and are found incidentally. But they rarely present with conductive hearing loss, otalgia, mass, aural fullness, tinnitus in large lesion completely occluding the EAC. Diagnosis is based on clinical examination, radiographic imaging, and histopathology. They are often confused with EAC exostosis and must be differentiated from EAC osteomas.

After examination and imaging, it was diagnosed as right EAC osteoma. surgical excision via post auricular approach was done
