Multiple Osteomas of Eustachian Tube Causing Ipsilateral Otitis Media

Area of Science:

• Otolaryngology
• Radiology
• Pathology

Background:

• The eustachian tube (ET) is crucial for middle ear ventilation and secretion drainage.
• Dysfunction of the ET, including obstruction, can lead to otitis media.
• Osseous obliteration of the ET is an uncommon condition.

Observation:

• A 53-year-old woman presented with otalgia and otorrhea.
• Temporal bone CT revealed middle ear opacification and near-complete blockage of the left ET lumen.
• Multiple osseous lesions, likely osteomas, were identified within the ET wall.

Findings:

• The case describes multiple osseous lesions consistent with osteomas within the eustachian tube.
• These lesions caused significant obstruction of the ET lumen.
• The obstruction led to ipsilateral otitis media, confirmed by CT findings.

Implications:

• Radiological features of ET osteomas are not well-documented due to rarity.
• Osseous lesions in the ET should be considered in cases of unilateral chronic otitis media.
• This case underscores the need to evaluate the eustachian tube in specific otological conditions.
