AbstractTo obtain the best possible results of treatment of acquired cholesteatoma, we made a subdivision of cholesteatoma types into attic and pars tensa cholesteatomas, and subdivided the latter further into tensa retraction cholesteatoma and sinus cholesteatomas. Tensa retraction cholesteatoma is defined as arising from a retraction or perforation of the whole pars tensa, whereas sinus cholesteatoma is defined as arising from a retraction or perforation of the postero-superior part of the tensa. We present the long-term results obtained in tensa retraction cholesteatomas treated with one stage surgery from 1964 to 1980. Median observation time was 9 years, range 2 to 19 years. Sixty-one ears were treated without mastoidectomy, whereas 71 ears had canal wall-up mastoidectomy and 64 ears had canal wall-down mastoidectomy. The total recurrence rate was 13.3 per cent; 17 ears had residual cholesteatoma, and nine ears had recurrent cholesteatoma. The best results were obtained in ears with an intact ossicular chain where mastoidectomy was not performed. In 49 per cent of the cases, the cholesteatoma was confined to the tympanic cavity without reaching the aditus, antrum or mastoid process. About one-third to one-quarter of the ears had tympanoplasty only, with removal of the cholesteatoma through the ear canal.

Long Term Recurrence Rate

AbstractDuring the years 1979–81, three different surgical techniques were used in the treatment of 87 ears with extensive cholesteatoma. All procedures were performed in one stage by the same surgeon. Ten to 13 years after the operations about 70 per cent of ears operated on by the canal wall up technique had developed a new cholesteatoma, which in most cases was recurrent, or a deep retraction pocket. A modification of this technique with mastoid obliteration resulted in a similar failure rate. In contrast, ears operated on by the canal wall down technique (in most cases with mastoid obliteration) had acceptable stability with a long-term recurrence rate of about 15 per cent. Most patients in the canal wall down group had a dry ear without significant cavity problems. Hearing in these patients was as least as good as hearing in patients with a preserved canal wall. We conclude that a meticulous one-stage canal wall down technique in ears with extensive cholesteatoma results in a high percentage of unproblematic, stable ears with satisfactory function. In contrast, if the posteriorcanal wall is preserved, recurrent cholesteatoma is the rule more than the exception.

Canal Wall Down Mastoidectomy

AbstractBackgroundRetraction pocket theory is the most acceptable theory for cholesteatoma formation. Canal wall down mastoidectomy is widely performed for cholesteatoma removal. Post-operatively, each patient with canal wall down mastoidectomy has an exteriorised mastoid cavity, exteriorised attic, neo-tympanic membrane and shallow neo-middle ear.ObjectiveThis study aimed to clinically assess the status of the neo-tympanic membrane and the exteriorised attic following canal wall down mastoidectomy.MethodsAll post canal wall down mastoidectomy patients were recruited and otoendoscopy was performed to assess the neo-tympanic membrane. A clinical classification of the overall status of middle-ear aeration following canal wall down mastoidectomy was formulated.ResultsTwenty-five ears were included in the study. Ninety-two per cent of cases showed some degree of neo-tympanic membrane retraction, ranging from mild to very severe.ConclusionAfter more than six months following canal wall down mastoidectomy, the degree of retracted neo-tympanic membranes and exteriorised attics was significant. Eustachian tube dysfunction leading to negative middle-ear aeration was present even after the canal wall down procedure. However, there was no development of cholesteatoma, despite persistent retraction.

Introduction: Radical mastoidectomy and tympanomastoid obliteration with fat tissue, also called the Rambo operation, is proposed to those patients suffering chronic middle-ear disease, with or without cholesteatoma, who have no useful hearing in an ear which cannot be kept dry despite all conservative treatment.Methods: We analysed retrospectively a series of 46 patients operated upon in our department. Information recorded included the surgical indications, surgical observations, post-operative care and complications. All patients were invited to comment on their long term anatomical and functional results and to express their degree of satisfaction with the procedure.Results: Recurrent infectious episodes were observed in seven cases. Residual cholesteatoma were observed in three cases. After treatment, these patients did not present with further complications. One case presented with multiple episodes of infection with recurrences of cholesteatoma and finally had the obliterated cavity transformed into an open cavity again. For most of the patients, in the long term (i.e. one to 23 years post-operatively (mean eight years)), the operation resulted in a dry ear, ending the need for frequent consultations to clean and disinfect diseased ears or open cavities.Conclusion: Obliteration of the tympanomastoid cavity, as proposed by Tom Rambo, shortens considerably the post-operative care period, in comparison with canal wall down mastoidectomy, and is therefore indicated if no serviceable hearing can be expected. In the long term, the rate of complications is low and patients are satisfied.
