上顎骨切除患者における構音の臨床評価法

The influence of maxillectomy on speech sound articulation and intelligibility were　studied by ten cases. These cases were anatomically classified into Type I (unilateral),　II (unilateral), and III (bilateral) in maxillectomy type. Pressure consonants, such as　plosives [p, b, t, d, k, g], fricatives [s, ç] and affricates [ts, dz, tʃ, dʒ], were defective　in maxillectomized patients. Vowels [i, u] were inclined to be hypernasal. Nasal　consonants [m, n] and fricatives [F, h; j, w] were rarely misarticulated. Dental　obtulator, denture or maxillo-dental prosthesis for unilateral maxillectomy produced　effective recovery of speech in most of cases, but did not so much for bilateral maxillectomy.　When patients with unilateral maxillectomy (Type I or II) obtained intraoral　pressure ratio of 0.8 or more with the use of such prosthesis, their speech became　intelligible. The patients with bilateral maxillectomy (Type III), however, could not　attain to such acceptable speech level. Articulation test composed of eight consonants　[p, b, t, d, k, g, s, ç] and five vowels [a, o, e, u, i] is recommended for such patients　conclusively in consideration of this experimental result

Multiple Congenital Epulides in A Newborn : With Special Reference to Reported Cases in Japan

This report describes a case of multiple epulides which simultaneously occurred on the maxilla and the mandible of a 6-day-old female baby. The clinical findings, diagnostic procedure, surgical treatment, histopathology, and 2-year follow-up of this case are presented. Based on the clinicostatistical and histopathologic investigations with special reference to the pertinent Japanese literature, a possible histogenetic etiology of this entity is discussed. Any odontogenic component might play an important role in the developoment of this tumor. This case of multiple epulides is considered to be very rare
