RESUMEN
Transnasal swab testing for the detection of SARS-CoV-2 is well established. The Centers for Disease Control and Prevention advocates swabbing either of the anterior nares, middle turbinate, or nasopharynx for specimen collection depending on available local resources. The purpose of this review is to investigate complications related to transnasal SARS-CoV-2 testing with specific attention to specimen collection site and swab approach. The literature demonstrates that while nasopharyngeal swabbing is associated with an increased risk of complications, it should remain the gold-standard test due to greater diagnostic accuracy relative to anterior nasal and middle turbinate swabs.

We present an unusual case of hypopharyngeal stenosis, secondary to radiation therapy for laryngeal squamous cell carcinoma, complicated by repeated inadvertent passage of a Maloney dilator through the larynx into the right mainstem bronchus during self-dilation. A brief review of esophageal/hypopharyngeal stenosis and management alternatives is presented. Self-dilation is presented as a therapeutic method for recurrent stenosis of the hypopharynx and esophagus. Recognition and avoidance of this complication is discussed.
