Radiological evaluation of the postsurgical middle ear

Area of Science:

• Radiology
• Otolaryngology
• Surgical Anatomy

Background:

• Postsurgical middle ear evaluation is challenging due to complex anatomy and diverse surgical techniques.
• Accurate interpretation requires knowledge of surgical procedures and expected radiological findings.
• Differentiating normal healing from complications is crucial for patient management.

Purpose of the Study:

• To describe common middle ear surgical procedures and their normal postsurgical radiological appearances.
• To review common causes of surgical failure in stapes surgery, chronic otitis media, and cholesteatoma surgery.
• To recommend the optimal imaging modality for assessing various middle ear pathologies post-surgery.

Main Methods:

• Review of common middle ear surgical procedures and their indications.
• Description of normal radiological findings following these procedures.
• Analysis of failure modes in specific middle ear surgeries and corresponding imaging strategies.

Main Results:

• Detailed description of surgical techniques and their typical postoperative imaging characteristics.
• Identification of frequent complications and their radiological signs.
• Guidance on selecting appropriate imaging techniques (CT, MRI) based on clinical scenarios.

Conclusions:

• Computed tomography (CT) is effective for evaluating middle ear prostheses and cavity aeration.
• Magnetic resonance imaging (MRI) excels at characterizing soft tissue occupation within middle ear cavities.
• MRI is the preferred method for monitoring cholesteatoma after closed mastoidectomy.
