Paratracheal air cyst (PTAC) as a rare complication after surgical closure of a tracheostoma: a case report.
Authors
Introduction Prelaryngeal tumors can be caused by various entities. Patient history and ultrasound can often determine the correct diagnosis.
Case There was a 50-year old patient presenting with a persistent prelaryngeal swelling. He stated that he had noticed a progressive lump on his neck for a couple of months. Furthermore, he had had a permanent tracheotomy about 20 years ago after a neurosurgical removal of a benigne brain tumor. The surgical closure oft the tracheostoma was performed about three months after the initial surgery.
Results An approximately 4 cm pretracheal protrusion was found at the time of investigation. Endoscopically no pathological findings were found on the larynx. Ultrasound showed an air cyst with near complete reflection of the ultrasound beam. Additionally, a CT-scan was performed which showed a cyst like tumor identified as a paratracheal cyst. An Endoscopy with tracheoscopy in general anaesthesia was performed showing a tissue draw-in on the ventral tracheal wall resulting in a valve mechanism of the tracheal cyst. After the cervical incision during the same procedure a large cyst was identified and removed in toto without damaging the cyst wall. The mucous tissue oft he trachea was closed using an inverting suture. The former Björk-flap was readapted to the ventral tracheal wall followed by a layer of infrahyoid muscles. The pathological results of the cyst showed no signs of respiratory tissue.
Conclusion Tracheotomy is a common surgical procedure. A pretracheal cyst is a rare complication after surgical closure of a tracheostoma. Both congenital and acquired tracheal cysts are rare. In addition to endoscopy, diagnostics include ultrasound and CT-scans. Exstirpation and multi-layered wound closure achieves good results.
