Younger patients may require secondary obliteration because of continued craniofacial maturation several years following canal-wall-down surgery. Mastoid obliteration may be valuable in the management of the well-developed and chronically wet mastoid cavity, particularly when the drainage emanates from mucosal disease or cell tracts in a deep sinodural angle. Multivariable-mixed effects analysis demonstrated a reduction in 0.1 visits per 6-month period following surgery overtime (p < 0.001). The secondary obliteration population was also significantly younger than the primary group (22.1 versus 43.5 years, p = 0.002). Eleven of the 13 secondary cases experienced cessation of otorrhea, achieving dry ears at rates similar to that of the primary and nonobliterated cases. In more than 80% of the cases, a dry ear was achieved, with no significant difference between the obliterated and nonobliterated cases (p = 0.786). Thirteen underwent secondary obliteration of existing mastoid bowls with chronic drainage, whereas 32 underwent primary obliteration at the original canal-wall-down procedure.Īchievement of a dry healed mastoid cavity and frequency of outpatient visits. We find Seofon and Eahta being greeted by the assembled leaders, although there is some grumbling in the corners about Evolve Sword getting all the support while the rest of Swordcraft withers away, though when pressed all go silent.
Eighteen mastoids were nonobliterated and 45 were obliterated. In the Eternal Castle of Swordcraft where Parades can last for days and the knights are endless in number. There were 63 canal-wall-down mastoidectomies for chronic otitis media with or without cholesteatoma between 20 with follow-up of at least 6 months. To evaluate the impact of mastoid obliteration on the achievement of a dry mastoid bowl and frequency of maintenance care.
