    We retrospectively analyzed 26 ears of 21 subjects having auditory ossicular malformation and who had undergone auditory reconstruction between April 2004 and December 2010 at our clinic. We checked preoperative condition, pathological classification, surgical procedure, and hearing improvement. We could predict pathological conditions precisely from preoperative computed tomography (CT), including incudostapedial disconnection (9/12, 75%) and malleus and/or incus fixation (7/12, 58%), which tended to be present in external ear malformation, and stapes footplate fixation (0/12, 0%). We could not, however, predict complex malformation (0/8, 0%). Overall success was 90% (18/20) in the 20 ears observed for at least 1 year. In the 2 ears without improved hearing, the first had congenital cholesteatoma and no stapes superstructure, was treated with type IV tympanoplasty. The second had malleus, incus, and stapes fixation and discontinuity between the incus and stapes, and was treated with type III tympanoplasty and stapes mobilization. Preoperative diagnosis is difficult in mixed congenital auditory ossicular malformation, especially stapes footplate fixation, possibly requiring unexpected procedures, with a poor hearing outcome. Preoperative status must thus be evaluated precisely using hearing, tympanometry, acoustic reflex test, and CT. Temporal bone CT and external ear findings are useful in diagnosing middle-ear malformation. Subjects' informed consent should also be obtained due to the possible need for changing procedure based on findings during surgery.

  • Consultation Patterns among Japanese Cedar Pollinosis Subjects at an Urban Clinic Report 2: a 20-Year Experience (1990-2009) in Chiyoda Ward, Tokyo

    To determine the consultation patterns of Japanese cedar pollinosis subjects during the pollen dispersal season, we surveyed those treated at a private clinic in Chiyoda Ward, Tokyo, from 1990 to 2009. We also studied the relationship between subject numbers and pollen count.
    The above relationship correlated highly with linear regression equation y=0.0897x+627.47 with R2=0.7851 (p< 0.001). The relationship from 1994 to 2009, when the study began in early January, correlated highly with logarithmic regression equation y=257.43Ln(x)-1014.8 with R2=0.9542 (p<0.001). Based on these results, we concluded that estimated pollen count helps predict the year's Japanese cedar pollinosis subject numbers very highly accurately.
    Numbers of subjects returning did not correlate well with pollen count, and continued to decrease each year. Return visits averaging 2.6 in 1990 gradually decreased to 0.73 in 2006 -a reduction we attributed to long-term medication and the increased self-payment proportion in medical expenditures.

  • A Case of Cervical Progressive Transformation of Germinal Center

    Progressive transformation of the germinal center is an unexplained borderline disease that presents as lymphadenopathy. The histological feature is an abnormally enlarged germinal center. Reports of this disease in otolaryngology are rare. A case of progressive transformation of the germinal center occurring in the bilateral multiple submandibular lymph nodes with swelling is presented. A 41-year-old man complained of bilateral painless cervical lymphadenopathy. Because fine needle cytology of the lymph nodes did not reveal any atypical cells, medical observation was performed. However, as the patient suffered from hoarseness, he consulted our hospital again. An otolaryngeal examination revealed mild enlarged bilateral lymphadenopathy. Removal of these lymph nodes to obtain a definitive diagnosis was performed. The pathological diagnosis was progressive transformation of the germinal center (PTGC). Immunostaining of the lymph nodes showed increased IgG4+cells (IgG4/IgG ratio=50%). To date, no significant changes in the cervical lymph nodes have been noted on follow-up. Because PTGC is apt to be misdiagnosed as Hodgkin's lymphoma, otolaryngologists should have full knowledge of PTGC.
