Opitz (BBB/G) syndrome: oral manifestations.

We studied a new case of the G (Opitz BBB/G) syndrome in a 12-year-old boy. Several relatives had partial manifestations of the disorder. A comprehensive dental evaluation of the propositus was conducted; included is, to our knowledge, the first published cephalometric analysis of a G syndrome patient.

The Rieger anomaly concomitant with multiple dental, craniofacial, and somatic midline anomalies and short stature.

An unusual, isolated case of the Rieger anomaly coincident with a multitude of dental, craniofacial, and systemic anomalies is described. Significant dental findings were severe enamel hypoplasia, conical and misshapen teeth, hypodontia, and impactions. Craniofacial disorders were underdevelopment of the maxilla, mandible, and anterior and posterior cranial bases, low-set ears, and a wide nasal bridge.

Dental development and the pharyngeal lymphoid tissue.

Because the teeth are housed and develop within the jaws, skeletal development of the maxilla and mandible is a primary factor in the consideration of any problems pertaining to the developing dentition. Growth of the posterior nasal choanae, the maxilla, and the nasopharynx should be evaluated as a unit in assessing the favorable or unfavorable character of the nasopharyngeal region. Both large and small adenoidal tissues should be examined in light of the morphologic character of the nasopharynx (be it small, large, narrow, or wide) and related to the developing maxilla.

Resection of a giant ossifying fibroma through an intraoral approach in a 9-year-old child: immediate reconstruction and 6-year cephalometric follow-up.

An unusual opportunity was afforded to study the growth and development of the facial structures of a 9-year-old child who underwent major mandibular reconstruction. The longitudinal studies confirmed the present concepts of the factors responsible for mandibular growth as well as their repercussions on other facial structures. An intraoral subperiosteal resection of a major portion of the right hemimandible sparing the upper part of the mandibular ramus was required to eradicate a large ossifying fibroma.

Early and late surgery in craniofacial dysostosis: a longitudinal cephalometric study.

Longitudinal clinical and cephalometric case studies are presented for two groups of patients with craniofacial dysostosis. The first sample includes two infants who underwent an extensive stripping procedure that was extended inferiorly to involve not only the coronal, but also the sphenozygomatic suture. The second sample includes two adolescents with midfacial hypoplasia who underwent a fronto-orbital-maxillary advancement.
