[Treatment of nasopharyngeal atresia with dual U-shaped mucosal flap repair and local dilatation].
OBJECTIVE
The aim of current work was to investigate the methodology and effect of dual U-shaped mucosal flap repair plus local dilatation for the treatment of nasopharyngeal atresia.


METHODS
Nine patients with nasopharyngeal stenosis were treated with dual U-shaped flap to repair the wound of retropharyngeal and soft palate mucosa. and then dilated by implanting a silicone tube.


RESULTS
The silicone tube was removed 6 months after the operation. The transverse diameter of nasopharynx maintained at about 2.0 - 2.5 cm, and anteroposterior diameter at about 1.0 cm. All cases had good nasal patency except velopharyngeal insufficiency and nasal regurgitation of food. After a 2 years follow-up, all cases had a good result except one still had the nasal regurgitation of food.


CONCLUSIONS
U-shaped mucosal flap repair with local dilatation is an effective method for treatment of nasopharyngeal atresia.
