Abstract: Cystic hygroma is benign tumor usually present in the neonate or in early infancy. Swelling usually occurs in neck and may involve the parotid, submandibular area, tongue and floor of mouth. It is a common condition in pediatric age group. But very rare in adult patients [1]. Cystic hygroma is a real challenge to the anesthetic in regard to airway management when presents in cervical region because tumor can extent from mouth to thoracic region[2]. Huge neck swelling revealed a dilemma of difficult intubation, but all neck swelling are not always difficult to intubate. In our both the cases the swelling was huge but we have intubated under general anesthesia with the help of mackintosh laryngoscope.
