ObjectiveTo observe the effect of natal cleft dermis slice transplantation combined with silicone prosthesis implantation applied to nasal tip rhinoplasty. MethodsTwenty-eight patients who had lower nasal dorsum and bulbous nose tip, and 5 patients who reported nose tip skin thinning due to prior augmentation rhinoplasty with silicone prosthesis were involved in the surgery. A combination of natal cleft dermis slice and nasal prosthesis, developed by suturing the natal cleft dermis slice to the tip of prefabricated nasal prosthesis, served as one implantable unit under nasal dorsal fascia for augmentation rhinoplasty to thicken nasal tip skin and achieve perfect appearance of nosal tip. ResultsAll patients were followed up for 6-12 months with a favorable efficacy, presenting a natural, harmonious and elegant appearance of nose tip , no nasal tip skin thinning due to obvious absorption in nasal tip was noted, neither skin ulceration in nasal tip nor prosthesis exsertion was observed. ConclusionThe application of natal cleft dermis slice transplantation combined with silicone prosthesis to augmentation rhinoplasty can increase the thickness of nasal tip, remodel nasal tip, effectively prevent complications such as nasal tip skin thinning, prosthesis downslide and exsertion caused by the direct action of prosthesis on nasal tip skin after augmentation rhinoplasty, and has the advantages of concealed donor area, convenient material collection, and natural appearance and texture after nasal tip rhinoplasty.
