ABSTRACT
OBJECTIVE:
For successful canal wall up tympanoplasty (CWUT) for the treatment of cholesteatoma, the restoration of stable middle ear aeration is also important; however, little is known about the dynamics of such aeration or the optimal surgical procedure. In this study, alternative additional surgical procedure was selected based on the grade of middle ear aeration during the second-stage operation. SUBJECTS ANDMETHODS:
Patients included in this study underwent staged CWUT surgeries with mastoid cortex plasty (MCP) for well-aerated ears (grade 3) and bony mastoid obliteration (BMO) for poorly aerated ears (grade 2-0). Of the 115 ears included in this study, 62 were followed for more than 5 years. Recurrence rates with deep retraction pocket formation were assessed using the Kaplan-Meier survival analysis. The aeration was graded as 0, no aeration; 1, aeration of only the mesotympanum; 2, aeration of the entire tympanic cavity; and 3, aeration of both the tympanic and mastoid cavities.RESULTS:
No recurrence was observed in ears associated with grade 3 aeration that underwent MCP or in ears with grade 2 aeration that underwent BMO during second-stage surgery. For grades 0 and 1 aeration ears, the recurrence rates were 8.1% after 5 years and 12.5% after 10 years (p < 0.05), and the aeration of recurrent ears deteriorated to grade 0.CONCLUSION:
Aeration during second-stage surgery predicts the final outcome.Palabras clave
