High-resolution CT is well suited for the evaluation of the temporal bone, which has a complex anatomy with multiple small structures. Congenital, inflammatory, neoplastic, and traumatic lesions can affect the EAC. It should be considered early in the management protocol to avoid lengthy symptomatic periods, the symptoms of which ultimately may not heal with medical therapy alone. The external auditory canal is an S- shaped osseo-cartilaginous structure that extends from the auricle to the tympanic membrane. Conclusion: Symptomatic benign idiopathic osteonecrosis of the tympanic bone is well treated by provision of vascularized tissue to maximize the chance of bone healing and subsequent cure. The most common causes of external auditory canal masses are due to otitis mediasquamous and mucosal types, tubercular otitis media, malignant otitis externa, and benign tumors like osteomas, exostosis, pleomorphic adenoma, tumors from the ceruminous and sebaceous glands and malignant tumors like squamous cell carcinoma and rhabdomyosarcoma. Follow-up data (median 22 months) suggests that the technique provides a robust and long-lasting therapy. The adult external auditory canal (EAC) is divided into an outer one-third cartilaginous portion and an inner two-thirds bony portion. Patients with EACC typically present with otorrhea and a chronic, dull pain due to the local invasion of squamous tissue into the bony EAC ( 2 ). Introduction Human beings can hear sounds in the dynamic amplitude sensitivity range of almost 0 to 120 dB and in the frequency sensitivity bandwidth of approximately 0.02 kHz to 20 kHz ( 1 ).

All 5 patients achieved a healed external auditory canal, with no ongoing skin ulceration or bony sequestration. External auditory canal (EAC) cholesteatoma (EACC) is a rare entity with an estimated occurrence of one in 1000 new patients at otolaryngology clinics ( 1 ). EAC overhangs are problematic since they obstruct the view of the tympanic membrane (TM) and middle ear, possibly creating diagnostic and surgical difficulties. Results: The described technique was performed on 5 patients following prolonged periods of failed medical therapy (minimum 8 months). Abstract Objectives: To characterize anatomic variants of the external ear canal (EAC), specifically canal wall overhangs. The ear canal is a narrow, tube-like structure that extends from the outer ear to the eardrum.

Methods: Success with this technique is described in a retrospective case series format in addition to a review of the existing literature on surgical techniques for the treatment of this condition. The inner ear includes the cochlea and semicircular canals. A 55-year-old female patient was referred to our institution as a potential candidate for an ongoing clinical study.

The technique of bony sequestrectomy, followed by rotation of a vascularized fascial flap and then a free full-thickness skin graft is presented.
Key Words: External Auditory Canal, Exostosis, Osteoma. Background/Aims: Benign idiopathic osteonecrosis of the external ear canal remains a challenging management problem, with many patients experiencing a prolonged chronic course requiring frequent debridement. present a case report of 22 year old female with External auditory canal osteoma in left ear.
