    Purpose: We evaluated the clinical utility of cartilage palisade tympanoplasty (CPT) in adhesive otitis media, a condition known to recur frequently with poor success in hearing gain.
    Objective: Specimens were 9 ears having adhesive otitis media and undergoing CPT in January 2006 and December 2007. Cases of pars tensa cholesteatoma were excluded. Mean subject age was 35.2 years. Seven had total drum adhesion and 2 posterior half-adhesion. Preoperative pure-tone hearing averaged 20-102 dB (mean: 56 dB).
    Methods: A small piece of cartilage harvested from the cymba was obliquely sectioned to yield wide, thin cartilage strips. Strips were overlapped slightly anteriorly to posteriorly parallel to the malleus handle when present. Tympanoplasty type 1 was conducted in 2 cases, type 3c in 6, and type 4c in 1.
    Results: No ears undergoing CPT produced recurrent adhesion or perforation although 2 suffered transient partial erosion healed easily in topical management. An air-bone gap of<15 dB was achieved in 3 ears, a hearing gain exceeding 15 dB in 5, and a hearing level of less than 30 dB in 3. Conditions falling in at least 1 of the above categories are considered successful based on Japan Otological Society criteria. Seven of the 9 (78%) were regarded as audiologically successful.
    Conclusion: CPT conducted for adhesive otitis media appears worthwhile, given the present better-than-expected results in our cases, although further study is needed to confirm this conclusion.

    Noise-induced hearing loss due to long-term work in extremely noisy places cannot currently be treated effectively, making it especially important to prevent such loss through occupational health management. We studied problems identified in a survey on occupational health management implementation given in Guidelines for Preventing Noise-Induced Disorders, together with possible corrective measures. Questionnaires mailed in 2005 to 1,000 Saitama Prefecture business sites were returned by 346 (response: 34.6%). We analyzed 140 noise-producing business operations. We found that (1) among sites having operating hazards, noise-inducing operations occurred most often in the manufacturing industry; (2) the companies analyzed lagged furthest behind in managing auditory occupational health; and (3) the smaller the site, the less occupational health management was implemented. Organizations such as occupational health centers and labor bureaus must work togather to implement auditory management at medium and small sites. It is also important to support auditory management through the aid of specialists in noise-induced hearing loss authorized by the Oto-Rhino-Laryngological Society of Japan.

    A 56-year-old man with bilateral hearing impairment who had taken betamethasone combined with dexchlorpheniramine maleate for 7 years to treat chronic sinusitis developed a dry cough after discontinuing this medication and was diagnosed with asthma, and after which he sensed impaired bilateral hearing. Based on the presence of numerous eosinophilic leukocytes in otorrehea, we made a diagnosis of eosinophilic otitis media, and he was prescribed predonisolone to control the asthma, but discontinued it on his own. He then developed fever, maniphalanx stiffness, testicular pain, and facial hyperesthesia, eruptions, and the lower-limb numbness. The detection of a positive serum reaction for MPO-ANCA and evaluated of eosinophilic leukocyte levels yielded a definitive diagnosis of CSS, for which the man was treated with predonisolone and cyclophosphamide. His symptoms were relieved, even though the onset of neutropenia, necessitated the discontinuation of cyclophosphamade administration.
