An articulation after operation in a case of hemiglossectomy -Investigation by a dynamic paratography- The authors examined articulation after operation in a hemiglossectomy case and reconstitution by a skin flap with dynamic paratography and clarity of pronounciation. Results 1) The clarity of pronounciation in this case was assumed to be due to three causes. First was considered that the grafted skin flap was upper convex and the reconstituted tongue had a same height as the remaining tongue. Second, that the remaining muscle in tongue could elevate the reconstituted tongue. Third that the remaining tongue had a freely movable tip of 1.5 cm, so that the reconstituted tongue could elevate that tip of the reconstitued tonge. 2) In this case, disordered articulation was found in r, t, fi, tri, ni, kin, no. 3) In a line, (sa) was mistaken as (a) and (m) as (sa). 4)(i) line had a tendency to listed as most abnormal articulation, and (o), (u), (a) and (e) line as more abnormal articulation. 5) In this case, the time to articulate a plosive of a consonant was somewhat longer after the operation and the plosive of a consonant had a tendency to become a friction. 6) The grafted skin flap not only covered the wound but also had an important complementary function that elevated the intraoral pressure and form the route of the expiratory outflow in the articulation. This case demonstrated that the form of the grafted skin flap in the reconstituted tongue had an important function in articulation.
