Osteoma of mastoid process obstructing external auditory canal: A case report

Abstract

Objective: To discuss the surgical treatment of recurrent osteoma of the mastoid process of the temporal bone, that obstructed external auditory canal causing unilateral conductive hearing loss. Setting: The study was carried out in ENT Clinic, University Clinical Center of Kosovo, Prishtina, Kosovo. Design: Retrospective review of a clinical case. Patient, Intervention and Result: We treated surgically with success a 14-year-old boy with osteoma of mastoid process, obstructing the external auditory canal of the left ear and causing conductive hearing loss. Axial and coronal computed tomography scans revealed an compact bone lesion that obstructed the canal. Complete removal of the lesion was achieved by a retroauricular approach. Conclusion: In order to achieve complete removal of the osteoma, drilling of the lesion must be performed not through the tumor, but around the osteoma, in the surrounding bone tissue

Stylomastoid Foramen Osteoma: Unique Challenges for Appropriate Management

“…It is reported that in cases of osteomas extending into the fallopian canal, complete excision is not indicated since there is risk of damage to the facial nerve [14]. However, it is reported also that partial surgical excision by drilling on the tumor tissue may result in recurrence of tumor that may grow medially to encroach on vital structures making potential future revision excision challenging [14]. The definitive treatment of osteoma remains of complete resection by drilling around the osteoma and avoiding damage to vital structures [15].…”
