Some patients with autoimmune disease will experience otologic symptoms, such as pain and hearing loss. We present a patient ANCA-associated vasculitis who required surgery for suspicious mastoid lesion associated her disease.

Cochlear implantation in canal wall down mastoid (CWD) cavities is fraught with the issue of how best to manage the mastoid cavity. Decision points include whether the external auditory meatus should be overclosed, whether the implantation should be staged, or even if the eustachian tube should be plugged. Given these options, we sought to describe our experience of cochlear implantation in CWD...

BACKGROUND AND AIM Dorsal augmentation of the nose is needed after trauma, rhinoplasty or for ethnic reasons. Alloplastic or autogenous materials may be used. In this paper, postauricular mastoid fascia was used for dorsal nasal augmentation. METHODS This study included ten patients who underwent dorsal nasal augmentation. Fascia over mastoid area was taken in all cases and was fixed with Ste...

Results: Cephaloauricular angle measurements of patients before the operation ranged from 46 to 57-degree. The median cephaloauricular angle was 51-degree. The recorded upper pole-to-mastoid distance ranged from 15 to 27 mm. The median upper pole-to-mastoid distance was 20 mm. After the operation, the median upper pole-to-mastoid distance was 12 mm. The postoperative median cephaloauricular ang...

Dermoid cysts of the head and neck are rare lesions. An unusual dermoid cyst in the subcutaneous tissue of the mastoid region is easily confused with lymph node abnormalities; therefore, diagnosis and treatment are often challenging. We describe a 22-year-old male with an unusual dermoid cyst in the subcutaneous tissue of the mastoid region whose only complaint was a retroauricular lump, which ...

IMPORTANCE Heterotopic glial tissue is a rare, benign congenital anomaly that can present as a fibrous mass with or without overt signs of neural tissue origin, such as overlying alopecia, pigmentation, or a "hair collar" sign. These lesions are typically found in the midline area, though they have been found laterally involving the mastoid and middle ear regions. As demonstrated by this case r...

OBJECTIVES Mastoid obliteration is used to obliterate the mastoid cavity following a mastoidectomy or to prevent the formation of a retraction pocket. This study evaluated the effectiveness of β-tricalcium phosphate and polyphosphate (β-TPP) for mastoid obliteration in middle ear surgeries in prospective human and animal studies. METHODS Twenty patients with chronic otitis media underwent mas...

Objectives: Mastoid obliterations are performed for a variety of indications, including chronic otitis media with cholesteatoma. One risk is of masking cholesteatomatous debris, which can subsequently proceed medially and cause suppurative complications. This study hypothesizes that autologous cranial bone graft used as bone pate (BP) in mastoid obliteration is of a lower density than surroundi...

OBJECTIVES To evaluate the usefulness of silicone blocks as graft material for mastoid cavity obliteration in the prevention of problematic mastoid cavities after canal wall down mastoidectomies. METHODS Retrospective evaluation of 20 patients who underwent mastoid obliteration with silicone blocks between 2002 and 2009 at the Chonnam National University Hospital. The cases consisted of 17 pa...
