초록

There have been heated controversies over the choice of the canal wall down mastoidectomy
(CWD) and canal wall up mastoidectomy (CWU), which are operational methods used to eliminate the lesion of cholesteatoma.
Combining the advantages of both methods, we reconstructed the posterior canal wall with conchal cartilage plate and
obliterated mastoid cavity with bone chips (group I), or hydroxyapatite mixed with bone chips (group II) since 2001. This
study was designed to evaluate the surgical outcomes of posterior canal wall reconstruction with mastoid obliteration in the
treatment of cholesteatoma. Subjects and Method：From January of 2001 to March of 2007, the posterior canal wall
reconstruction with mastoid obliteration was conducted on 66 patients. There were 30 cases of cholesteatoma and 36 cases of old
radical cavity. The postoperative observation period ranged from 5 to 74 months, with the average period of 34.7 months. We
analyzed the postoperative complications, and hearing results of the 33 ossicular reconstruction cases. Results：There was 1
case of residual cholesteatoma in the middle ear cavity, but no recurrent cholesteatoma. In most cases, reconstructed canal wall
was maintained well, but partial canal wall resorption and postauricular dimpling occurred in 5 cases of group I. On the other
hand, the epithelization of posterior canal wall was incomplete in 4 cases of group II. After surgery, no patients complained any
cavity problems at all. Conclusion：The present study suggests that this procedure can prevent cavity problems and reduce the
recurrence of cholesteatoma with destructed canal wall. (Korean J Otorhinolaryngol-Head Neck Surg 2008;51:33-40)
