Abstract

OBJECTIVES:

In order to evaluate the results of tympanoplasty in one stage middle ear cholesteatoma surgery, a retrospective study of 180 consecutive cholesteatomas operated on was undertaken.

METHODS:

150 single procedures and 30 revision surgeries realized between 1992 and 1997 were analysed by studying anatomical and functional results with a mean follow-up of 24 months.

RESULTS:

Among the 150 adult patients, 85 (57%) were previously operated on in other centres and presented a recurrence of cholesteatoma. Closed technique was performed in 110 cases (61%) and opened one in the remaining cases (41%). Ossiculoplasty was made in 101 cases (56%) with different materials (15 incus autografts, 14 teflon prosthesis, 35 hydroxyapatite (HA) composite prosthesis and 37 all in HA prosthesis): 91 cases in a one-stage procedure but 10 worse functional results required a closed revision procedure. Twenty cases were also revised after one year of follow up at least: six recurrences of cholesteatoma were operated on by using canal down mastoidectomy (4%), 14 limited residual cholesteatomas (9.3%) had a revision closed technique procedure. CT Scan followed up all the patients operated on by a closed technique. Postoperative air-bone gap (ABG) was 20 +/- 11.3 dB and 27 +/- 10.1 dB in closed and opened techniques, respectively (p < 0.05). ABG was 20 +/- 9.2 dB and 26 +/- 13 dB in type II and type III tympanoplasty, respectively (p < 0.05).

CONCLUSION:

If the tympanic and posterior cavities are reasonably safe, middle ear cholesteatoma in adults can be well cured by a one-stage procedure including ossicular chain reconstruction with hydroxylapatite prosthesis covered with cartilage graft who achieved a valuable hearing restoration.
