We use the work of Pfaltzgraff on subordination chains in C-n to recov
er a growth theorem for starlike mappings of the unit ball established
recently by Barnard, FitzGerald and Gong. We also introduce a class o
f strongly starlike maps for which we construct, aided by the aforemen
tioned technique, an explicit quasiconformal extension to C-n. Several
examples are discussed at the end.
