We present the case of a 2-year-old male with a complex left cervical venolymphatic malformation who underwent doxycycline sclerotherapy at 12 months of age complicated by new onset pulmonary aspiration. A review of the literature reveals this to be a rare complication of sclerotherapy and only the second reported case. Methods: Procedural details with associated imaging including endoscopic airway and swallowing evaluation are included. A literature review of cervical and laryngeal sclerotherapy complications was performed and discussed. Results: A 12-month-old male underwent sclerotherapy with doxycycline for a complex parapharyngeal and paralaryngeal venolymphatic malformation. The postoperative course was complicated by new onset dysphagia, aspiration, and decreased laryngeal sensation. Gastric feeding and swallowing therapy were necessary due to prolonged difficulty. The sclerotherapy treatment resulted in near elimination of the cervical components of the lesion at 12 months follow up. The child progressed to total oral feeding by 17 months post-treatment with no evidence of decreased laryngeal sensation. An extensive literature review identified only one reported case of new onset dysphagia and decreased laryngeal sensation after doxycycline sclerotherapy. Conclusions: Doxycycline sclerotherapy for cervical venolymphatic malformations rarely can cause adjacent neural injury resulting in laryngeal complications. Our case report and literature review suggest that symptom management and appropriate aspiration precautions are necessary in infants or children with presumed vagus or laryngeal nerve injury, and injury is likely only temporary.
