title: Long-term results after using dynamic presurgical nasoalveolar remodeling technique in patients with unilateral and bilateral cleft lips and palates.
abstract: OBJECTIVE
  To evaluate the effects and durability of results after using dynamic presurgical nasoalveolar remodeling in patients with unilateral and bilateral cleft lips and palates.
  
  
  METHODS
  Dynamic presurgical nasoalveolar remodeling technique does not rely on the relatively static force exerted by the orthopedic plate held in place by means of tape or adhesives. The principle behind this procedure is the use of the force generated during suction and swallowing to produce the remodeling effects on the nasal structures. The nasal component acts not only on the nasal structures but also in the lip function by stimulating labial muscle contraction. Direct anthropometry performed before primary reconstruction of the lip and nose and 1 year later posterior to surgery suggests that results are permanent.
  
  
  CONCLUSIONS
  When the dynamic presurgical nasoalveolar remodeling protocol is instituted early, it can avoid memory cartilage fixation. Changes incorporated to the nasal extension allowed us to obtain better results, elevating the nasal tip, remodeling the depressed cleft side alar cartilages in unilateral cases, and repositioning and correcting the positional alteration of the nasal cartilages building a new columella in bilateral cases. In addition, comfort and tolerance of patients has been improved, and adjustments needed during follow-up have been simplified, significantly reducing the consultation time and increasing the interval between appointments. The obtained outcome facilitates primary surgical cleft lip and nose reconstruction and improves surgical results.
