The difference of transepidermal water loss(TEWL) between normal persons and patients with eczematous external otitis was identified by statistical analysis. In this study, 20 healthy volunteers without history of atopic dermatitis and 20 patients with eczematous external otitis were participated. Measurements were performed at ear lobes and other various anatomical sites(proximal forearm, mid forearm, distal forearm, palm, upper back, lower back, leg(shin), leg(calf), and sole) by Tewameter TM 210(Courage;Rhazaka, Koln, Germany). Prior to the procedure, subjects stayed still for 30 minutes in the room where the temperature was controlled(18-23degreesC) with a relative humidity of 35-45%. The results are summarized as follows:1) TEWL values at ear lobes were higher in patients with eczematous external otitis than in normal persons(p<0.05). 2) TEWL values at other various anatomical sites except upper back were higher in patients with eczematous external otitis than in normal persons(p<0.05).

Skull base osteomyelitis is originated from inappropriately treated chronic infections near the skull base. If diagnosis and treatment are delayed, it occasionally causes multiple cranial nerve palsy, with the mortality rate being as high as 60%. Skull base osteomyelitis typically evolves as a complication of external otitis in diabetic patients, so it has been thought as a synonym for malignant external otitis. However, the routes of infection are diverse. We experienced two patients of atypical skull base osteomyelitis after mastoidectomy. It is an unusual complication of mastoidectomy, so we report about these cases.

Malignant otitis externa (MOE) originates as inflammation of the epidermis in the external auditory canal, and spreads to the surrounding structures and neck, leading to abscess formation. MOE is associated with an immunosuppressive condition and diabetes. Patients with MOE suffer from otalgia, otorrhea and hearing loss. According to the literature, surgery to the temporomandibular joint is controversial as the treatment of choice.

Otitis externa and otitis media spreading to the temporomandibular joint (TMJ) is rare, and infection to the TMJ may result as well from direct spreading from the adjacent structures or from hematogenous spreading. But, apparent pathomechanism is not identified clearly and more specific studies are required. We experienced 2 cases of otits media and otitis externa which involved dehiscence of the bony canal wall that communicates with TMJ and the glenoid cavity. We report this cases with literature.

BACKGROUND AND OBJECTIVES: The change of pH in the external auditory canal (EAC) is an important factor in the pathogenesis of otitis externa. However, there is a lack of study focused in this area. Thus, we investigated the differences in the pH in the EAC between several different patient groups of otitis externa and the control group. SUBJECTS AND METHOD: There were 100 patients with otitis externa and 150 normal controls participated in this study. Patients with otitis externa were divided into 3 groups; acute or subacute infective otitis externa, chronic infective otitis externa and chronic allergic otitis externa. The pH of the EAC was measured in otitis externa patients and control subjects on their first visit. RESULTS: The mean EAC pH of the normal control subjects was significantly higher than that of the skin of other parts of the body. The pH difference among the 3 patient groups was statistically significant (the pH of acute or subacute infective otitis externa=6.83+/-0.64; the pH of chronic infective otitis externa=6.16+/-0.67 and the pH of chronic allergic otitis externa=5.78+/-0.59). CONCLUSION: The change in the pH of EAC can be considered as a predisposing factor of otitis externa. We quantified the level of pH at the EAC among three groups of otitis externa patients, and the results showed that the pH difference among the three patient groups was statistically significant. This study warrants a further investigation focusing on the proper choice of eardrops for otitis externa patients according to their pH at the EAC.

There are many underlying diseases which cause chronic otitis externa, including contact dermatitis, seborrheic dermatitis, dermatophytosis and so on. Allergic contact dermatitis caused by a hearing aid is a rare condition, but it is important because the patient would have difficulties in hearing without use the of a hearing aid. We herein report a case of allergic contact dermatitis caused by a hearing aid, which has been diagnosed by patch tests, along with the review of the literature.
