Chronic Pyriform Sinus-Pleural-Mediastinal Fistula Secondary to an Internal Penetrating Trauma by a Toothbrush

Abstract

Objective: To report an unusual case of pyriform sinus-pleural-mediastinal fistula secondary to internal penetrating trauma by a toothbrush, with emphasis on management options. Case report: A 26-year-old woman swallowed a toothbrush in a violent manner 8 months ago in an attempt of self-mutilation. She immediately complained of neck pain and dysphagia. She was diagnosed with pyriform sinus-pleural-mediastinal fistula. The fistula was repaired. Primary closure was performed and covered with the sternocleidomastoid muscle flap, and reinforced with thyroid tissue and surrounding tissues. The patient did not present any complications or recurrence, and she gained weight after the operation. Conclusion: Early recognition of hypopharyngeal perforation is important, and in selected cases, immediate repair of the perforation can lead to a good prognosis.
