Unilateral isolated incus agenesis: detection by virtual endoscopy

Area of Science:

• Otolaryngology
• Medical Imaging
• Surgical Innovation

Background:

• Incus agenesis, a rare congenital condition, presents diagnostic challenges.
• Accurate preoperative assessment is crucial for effective surgical planning in middle ear malformations.

Observation:

• A unique case of unilateral incus agenesis was identified.
• Virtual endoscopy provided significant preoperative diagnostic value.
• Thin-section temporal bone CT scans and 3D reconstructions correlated with intraoperative findings.

Findings:

• The study presents the first documented instance of unilateral incus agenesis.
• Virtual endoscopy proved effective for diagnosing this rare condition.
• Surgical intervention involved successful ossicular prosthesis replacement.

Implications:

• This case highlights the utility of advanced imaging techniques like virtual endoscopy in diagnosing rare ear malformations.
• The successful prosthetic replacement offers a viable treatment option for patients with incus agenesis.
• Further research into imaging modalities for middle ear anomalies is warranted.
