#Mastoid obliteration series

Four (7%) ears exhibited wound infection. Given the low probability of recurrence of cholesteatoma in an obliterated CWD cavity, the low rate of harmless complications (1032), and the more favorable results of mastoid obliteration compared to revision excision surgery, the future of otosurgery appears to be simultaneous surgery with lesion excision and reconstruction. Seven (12.5%) ears had residual cholesteatoma pearl in the middle ear at second-look surgery. Seven (13%) ears had occasional otorrhea, and three (5%) ears had small granulation tissue. Forty-six (82%) ears maintained a very small, dry and healthy mastoid cavity. Results: All patients underwent second-look surgery. If it is not possible to remove all cholesteatoma from the mastoid air cell tracts obliteration of the mastoid with bone pate is contraindicated. Data included mastoid cavity status, results at second-look surgery with ossiculoplasty, and postoperative complications. Mastoidectomy is performed to remove infected air cells within the mastoid bone caused by mastoiditis, ear infection, or an inflammatory disease of the. Seventeen (30%) ears were managed via revision surgery, with the reminder via primary surgery. Objective: To describe a technique for mastoid obliteration following canal wall down (CWD) mastoidectomy for chronic otitis media with cholesteatoma, and review its early results in producing a dry, safe ear, and a small mastoid cavity.

#Mastoid obliteration series

Materials and Methods : In a prospective longitudinal study with a mean follow-up of 28 months conducted between 2008–2012, a series of 56 ears in 48 patients with chronic otitis media due to a cholesteatoma underwent canal wall down mastoidectomy that their mastoid cavity obliterated with combined bone pâté and Palva flap. In this study, the lowest recurrent and residual rates were reported when combining the CWU tympanoplasty with mastoid obliteration, on average 0.28 and 4.2%, respectively.Introduction : This study was designed to evaluate the usefulness of mastoid cavity obliteration with combined bone pâté and Palva flap in the prevention of problematic mastoid cavities after canal wall down mastoidectomy. In CWU tympanoplasty with mastoid obliteration, these rates were 0.28% and 4.2%, respectively and in CWD tympanoplasty with mastoid obliteration, 5.9% and 5.8%, respectively.Ĭonclusions and Relevance We show the recurrent and residual disease rates after either CWU or CWD tympanoplasty with mastoid obliteration to be qualitatively similar to, if not better than, previously reported rates of for nonobliterative techniques. Of the 1534 patients who underwent CWD or CWU tympanoplasty with mastoid obliteration, the rate of recurrent disease was 4.6%, and the rate of residual disease was 5.4%. Modified radical mastoidectomy is the ideal surgical option in these cases but it results in open mastoid cavity formation with certain common cavity problems.

After assessing these remaining articles for methodological quality and relevance to the current topic, another 8 studies were excluded, and a total of 13 studies (1534 patients) were included. The full-text articles of the remaining 146 citations were assessed for eligibility, resulting in 22 articles. The methodological quality was determined using the methodological index for nonrandomized studies (MINORS) scale, and the relevance to the current topic was determined using a 4-criterion checklist.įindings The searches identified a total of 336 potentially relevant publications 190 articles were excluded based on title and abstract. Each study was reviewed by 2 independent reviewers on predetermined eligibility criteria.

The initial search was conducted in December 2016 and was updated in July 2017. Objective To systematically review the literature on recurrent and residual cholesteatoma rates after single-stage CWU and CWD tympanoplasty with mastoid obliteration.Įvidence Review A systematic search of literature was performed to identify relevant publications in multiple electronic databases. A more recently propagated surgical approach, to combine the CWD or CWU tympanoplasty technique with obliteration of the mastoid and epitympanum, is showing promising results. Conclusion: Canal wall down mastoidectomy and mastoid cavity obliteration with combined bone pt and Palva flap is a. Importance The ideal surgical treatment of cholesteatoma has been subject to discussion for years because both traditional surgical techniques (canal wall down and canal wall up tympanoplasty) have their own advantages and disadvantages.
