Tracheal stenosis caused by unnoticed foreign bodies

Area of Science:

• Pulmonology
• Otolaryngology
• Pathology

Background:

• Tracheal stenosis is a serious condition that can compromise airway patency.
• Microscopic foreign bodies are an unusual cause of tracheal stenosis.
• Intratracheal intubation is a common medical procedure with potential complications.

Purpose of the Study:

• To report an extremely rare case of tracheal stenosis caused by unnoticed microscopic fiber-like foreign bodies.
• To investigate the potential link between intratracheal intubations and the development of this condition.
• To describe the diagnostic and therapeutic approach.

Main Methods:

• A 66-year-old woman presented with dyspnea and inspiratory stridor.
• Diagnostic tools included magnifying electroendoscopy and computed tomography.
• Tracheotomy and biopsy were performed for histological examination.
• Treatment involved semiconductor laser photoresection.

Main Results:

• Magnifying electroendoscopy and CT revealed circumferential tracheal stenosis.
• Histological examination showed chronic inflammation and deposition of fiber-like foreign bodies.
• The patient had a history of four intratracheal intubations.
• Laser photoresection resulted in a good postoperative course.

Conclusions:

• This case represents the first report in English literature of tracheal stenosis caused by unnoticed foreign bodies.
• The fiber-like foreign bodies may be related to chronic inflammation secondary to repeated intratracheal intubations.
• Early diagnosis and appropriate intervention are crucial for managing such rare conditions.
