Let Λ be a domain in ℂ and let ... be meromorphic in We assume that is holomorphic in for fixed z.

The main theorem states: Let Λ 0 be a subdomain of Λ such that f λ is univalent in for . If has a quasiconformal extension to the closure of for one then f λ has a quasiconformal extension for all .

This result is related to a theorem of Mañé, Sad and Sullivan (1983) where the assumptions are however different. The main tool of our proof is the Grunsky inequality for univalent functions.

Palabras clave : Univalent function; quasiconformal extension; analytic parameter; Grunsky inequality.
