[A nasal congenital malformation not published in the literature: About 5 cases].

AIM OF STUDY: Five cases of the same congenital malformation of the nose, affecting the nasal dorsum and the supra-tip, were supported in our university plastic surgery center. This malformation has not been described in the literature known to the authors. The aim of this study is to analyze this nasal deformity.

PATIENTS AND

METHODS

Five children presented this congenital deformity between 1994 and 2014. The patients were examined and the malformation precisely described. Genetic and histological examinations were carried on. The diagnosis and treatment of this pathology were discussed.

RESULTS

This malformation associated 4 anomalies: hypertrophy of soft tissue of the dorsum located in the middle third of the nasal bridge, deformed alar cartilages turned back downward and outside, advanced support default and median skin brand similar to a scar. These patients showed no other abnormalities of the midline or respiratory disorders. No genetic disorder was found for these five patients, and no histological arguments were found. Three patients were operated, one until adulthood with a satisfying cosmetic result.

CONCLUSION

Bibliographic research has not allowed us to make an accurate diagnosis of this malformation that appears to be non-syndromic and to have a genetic origin. Our therapeutic approach became more clear and it now seems legitimate to propose early excision of fat mass to prevent alar deformations, associated with a cortico-cancellous graft, which in our experience grows with age, to support the tip.
