Introduction: The cholesteotoma is largely responsible for inducing the bones erosion. It commonly erodes the ossicular chain and infrequently the skull bones, including the labyrinth, which is the hardest bone in the body. Several scholars have remarked the aggressive character of the disease in children.
The main objective of the present study is the comparative research of bone lesions due to middle ear cholesteotoma in adult and in children, upon the post- surgery characteristics of the tympanic membrane.
Methods: A retrospective clinical study was performed on a number of 350 patients operated for cholesteatoma within the ENT Clinic of Cluj-Napoca during 2003–2005. The patients were divided in several groups upon the following criteria: age (over 16 years old, under 16 years old), the type of tympanic membrane perforation (type-1 Shrapnell perforation, type-2 post superior perforation of the tympanic membrane), location of the cholesteotoma, the ossicular lesions identified intrasurgery, the presence of complications. The Salleh and Mills classification was employed within the last three criteria. A non parametrical statistical data analysis, the Sperman R (p<0,050) test was applied.
Results: The cholesteotoma associated with type 1 perforation habitually connected with S2, o3, while the cholesteotoma associated with type-2 perforation most frequently connected with S3, o2 (p<0,050). Complications of the disease occurred regularly with type-2 perforation (11,4%) when compared to type-1 perforation (7,43%). No significant statistical differentiations were observed regarding bone lesions and complications in adults when compared to children.
