Analysis of Dental Arch Relationships in Swedish Unilateral Cleft Lip and Palate Subjects: 20-Year Longitudinal Consecutive Series Treated with Delayed Hard Palate Closure

Abstract

Delayed hard palate closure as practiced in Goteborg since 1979 has produced the best GOSLON Yardstick ratings in a consecutive series of patients ever recorded worldwide, since the Yardstick was first used in 1983. However, it is noteworthy that a new protocol has been introduced in Goteborg since 1994, in which hard palate closure is done at 3 years due to concerns regarding speech.
