Critical Stenosis Because of Vocal Cord Synechiae in a Child

Stridor is a clinical sign of an underlying disease and a common reason for pediatric emergency department (PED) consultation. Patients presenting with stridor must be evaluated to determine the origin of this abnormality. We present the case of a 7-year-old female patient who presented to our Pediatric Emergency Department with a history of recurrent episodes of stridor with increasing frequency over the previous 4 years, for this reason she was previously admitted to the pediatric intensive care unit. Findings from the otorhinolaryngologic assessment with flexible fiber-optic endoscopy led to a diagnosis of congenital synechia of the vocal cords. The cervical CT scan evidenced critical stenosis of the airway. An initial cordectomy and placement of a silicone device for fixation were performed. Subsequently, the patient required 6 additional interventions for progressive dilation of the glottic space at the level of the vocal cords and injections of mitomycin C injections (an antineoplastic that inhibits collagen proliferation). This case highlights the importance of additional studies (especially examination of the upper airway) when atypical or recurrent findings are revealed by the clinical history, physical examination, or disease course in patients with croup to prioritize cases severe enough to require pediatric intensive care unit admission.
