Pharyngeal malformation was found in a boy aged 12, who complained of marked abnor-mality of speech voice. As an infant the child had difficulty in sucking and also in brea-thing. In the right side of oropharynx the anterior pillar as well as the tonsillar fossa were completely absent and the right tonsil was closely adherent to a portion of the tin-gue root.
