One of the problems in secondary revision of the nose is the relapse of nasal morphology after surgery. We attempted to clarify the relapse of nasal morphology after secondary revision of the nose in unilateral cleft lip (UCL) patients. The subjects were 23 UCL patients who underwent secondary revision of the nose in our clinic. The average relapse ratio of naso-labial angle (NLA), height of nasal tip (Prn (x)), and alinasal width (Width) was 29.2%,29.2%, and 25.4% respectively. The amount of relapse from 1 month to 3 months postoperatively was largest, and then the degree of relapse from months to 6 months postoperatively decreased. After 9 months postoperatively, nose morphology was almost stable. According to the degree of morphological change of nose by operation, subjects were divided into two groups; large group, and small group. No significant differences were found between relapse of the large group and small group in measured NLA, Prn (x), and width at 1 year postoperatively. These results suggest that the relapse of nose morphology after secondary revision of the nose was about 30% whether morphological change of nose by operation is large or small.
