Stridor caused by duplication cyst in a female infant and temporary vocal cord paralysis. A case report.

ABSTRACT

INTRODUCTION AND IMPORTANCE Congenital hypopharynx duplication cysts are a medical rarity; nevertheless, they offer an important differential diagnosis in neonatal dyspnea or feeding problems. CASE REPORT Herein, we describe a case of delayed diagnosis but successful surgical removal of a large congenital hypopharynx cyst in a 4-month-old infant presenting with stridor. CLINICAL DISCUSSION: Early and proper diagnosis and surgical handling of hypopharynx cyst can help to achieve the best prognosis and outcome. CONCLUSION: We present the successful management of a newborn with a pharyngeal duplication cyst. In our case, the temporary postoperative laryngeal nerve palsy resolved within four weeks. Overstretching of recurrent laryngeal nerve might have caused this complication.
