Secondary correction of nasal deformities in cleft lip patients using acellular dermal matrix grafting on the nasal tip with open rhinoplasty

Abstract

Secondary nasal deformities in patients with unilateral cleft lip represent surgical challenges. Open rhinoplasty involving repositioning of the lower lateral cartilage has been shown to be a suitable technique for patients with cleft lip and nose deformities. This study aimed to explore a particular method of rhinoplasty and to assess the aesthetic outcomes for secondary unilateral cleft lip and nose deformities following its use. Fifty-seven patients treated for secondary unilateral cleft lip nasal deformities from January 2012 to December 2018 were enrolled in the study. Open rhinoplasty combined with a reverse-U incision and acellular dermal matrix grafting on the nasal tip was performed in all patients by the same surgeon. In our follow-up study we evaluated the results by measuring angles on photographs and scoring the appearance before and after operation. Data were statistically analysed using the t test. Appearances were improved in all patients. Both the alar base-nasal tip-columellar base angle and the nostril axis angles were smaller postoperatively (p < 0.001). According to the outcome scores, most patients (53/57) agreed that there was an obvious improvement in the appearance of their noses following surgery, and overall they were satisfied with the results of the revision procedure. A distinct improvement in nasal appearance can be achieved with this rhinoplasty. Our surgical method is effective and reliable in patients with secondary unilateral cleft lip and nose deformities, and is worth promoting in the clinic.
