Cleft lip and palate is a common congenital malformation of the oral and maxillofacial region, and its incidence is 1.82 ‰ in China, of which the incidence of unilateral cleft lip accounts for 70 ∼ 80% of the incidence of cleft lip.
1.Pre-surgical nasoglossus correction; 2.Simultaneous repair of cleft lip and nasal deformity in about 3~6 months; 3.Post-surgical nasal mold shaping for at least 6 months.
Pre-surgical nasoglossal orthoplasty is a pre-surgical orthodontic method to correct the nasoglossal deformity and restore the normal position of soft tissues by applying continuous force to the nasoglossal bone on the cleft side of the infant through an orthosis. Preoperative orthodontic treatment for cleft lip and palate patients can be started as early as two weeks after birth. Receiving preoperative orthodontic treatment before about 75 days after birth has good orthodontic efficacy and facilitates the implementation of surgery; at the same time, it reduces the scope and difficulty of surgery, thus ensuring the stability of postoperative efficacy and its long-term results.
The nasal deformity often recurs some time after surgery, both the skin and the cartilage have a tendency to revert, and they all need to be maintained for a certain period of time after surgery to heal in their new position, and postoperative nasal mold shaping is an important method to reduce this elastic retraction and stabilize the surgical results.
Nose molds are clear silicone home care products that are based on the normal shape of the nasal vestibule and are used to improve and ensure the results of post-operative nasal morphology after cleft lip surgery. Numerous cases and studies have found that the use of nasal molds is very effective in preventing nasal collapse and maintaining the symmetry of the nostrils. Wearing them after cleft lip nasal deformity surgery can induce the normal development of the external shape of the nasal vestibule and effectively prevent the deformity of the nostrils caused by scar contracture, which plays a very important role in the aesthetics of the nose. .
To sum up, the treatment of nasal deformity should follow the principle of comprehensive sequential treatment, and the most suitable treatment method should be adopted at the appropriate time to achieve the best results, which is conducive to the normal growth and development of the nose and eliminates psychological barriers for the majority of cleft lip and palate patients.
