title: [Surgical treatment of congenital ring constriction: standard Z-plasty flaps versus microsurgical excision (author's transl)].
abstract: The author discusses the advantages and drawbacks of two procedures for surgical treatment of congenital ring constriction: the standard Z-plasty flaps and microsurgical excision. In the general opinion merely excising the tissues of the annular groove and suturing the skin borders together fails because the circular scar contracts, reproducing the constriction. In 6 infants, microsurgical excision of the annular groove, using a Zeiss operating microscope OPMI 7 and microsurgical instruments, with suturing of the skin borders proved to be a reliable technique giving excellent cosmetic results. Provided that all fibrous tissue is excised there is no risk of secondary contraction.
