[Current aspects of paediatric cholesteatomas]

Area of Science:

• Otolaryngology
• Pathology
• Molecular Biology

Context:

• Cholesteatomas are classified as genuine or acquired.
• Theories for acquired cholesteatoma development include metaplasia, immigration, proliferation, and retraction pockets.
• Paediatric cholesteatomas present with more extensive and aggressive growth compared to adult forms.

Purpose:

• To explore the clinical and molecular differences between paediatric and adult cholesteatomas.
• To discuss the surgical management of paediatric cholesteatomas.

Summary:

• Molecular differences, including angiogenesis, cytokine expression, and heightened inflammatory responses in the perimatrix, may explain the aggressive nature of paediatric cholesteatomas.
• Surgical therapy for paediatric cholesteatomas requires adaptation to individual pathological findings.
• The canal wall up procedure is preferred for initial surgery when feasible.
• The "inside-out" mastoidectomy technique offers advantages in surgical overview and postoperative auditory canal function.

Impact:

• Provides insights into the aggressive nature of paediatric cholesteatomas.
• Informs surgical decision-making for paediatric cholesteatoma treatment.
• Highlights the potential benefits of specific surgical techniques for improved patient outcomes.
