摘要:

&NA;Distinct osseous structural differences exist between patients with unilateral coronal synostosis and those with “deformational plagiocephaly.” Patients with unilateral coronal synostosis exhibit significant anterior displacement of the infraorbital rim relative to the ipsilateral frontal bone and contralateral infraorbital rim (p < 0.005). Patients with deformational plagiocephaly are noted to have retrusion of the frontal bone and infraorbital rim on the involved side. The observed differences, documented utilizing computerized tomography, are easily appreciated on clinical examination, facilitating rapid distinction between these two entities.

摘要:

&NA;Craniofacial structures, the aortic arch, thymus, and parathyroid glands all arise from the embryologic pharyngeal pouches, and DiGeorge and Job craniofacial malformation syndromes have defined immunologic deficiencies. The question addressed by this study is whether patients with other pharyngeal pouch malformations could also have immunologic abnormalities. Twelve patients, 4 female and 8 male, were selected at random from the Tampa Bay Craniofacial Center. Their diagnoses included: cleft lip/cleft palate, hemifacial microsomia/Goldenhar syndrome, Treacher‐Collins syndrome, craniofacial hemangiomata, craniosynostosis syndromes, and Tessier 13 cleft. Fresh blood samples were analyzed against age‐matched controls for immunoglobin number, using immunoelectrophoresis, T‐cell, B‐cell, and natural killer cell quantity via Coulter counter and monoclonal antibody labeling, as well as lymphocyte stimulation and response functions with phytohemagglutinin, concanavalin A, pokeweed mitogen, andStaphylococcus aureusmitogens. All patients studied had some abnormality of their immune systems. Seven had specific T‐cell abnormalities and three patients had abnormalities in all three categories studied. This indicates that patients with any pharyngeal pouch malformation may have an abnormality of the immune system.

摘要:

&NA;The subcranial approach for the osteotomy of the skull base and orbital roof in cases with hypertelorism is described. Advancement of the fronto‐orbital segments is performed, avoiding the transfrontal procedure, thus making frontal lobe retraction unnecessary. The advantages of this method are pointed out.

摘要:

&NA;Mandibular and dentoalveolar deformities associated with cystic hygroma of the head and neck have previously been described. This small series has identified changes involving the entire craniofacial skeleton, attributable to both the local and distant effects of massive facial lymphangiomas, without evidence of any actual soft tissue ingrowth into bone.In view of the inability to excise such lesions and normalize the soft tissue anatomy, the surgical approach to the craniofacial skeletal abnormality should be to reserve the required osteotomies or ostectomies until the completion of facial growth.

摘要:

&NA;Tissue expanders, which are used to enlarge the soft tissue of the scalp, eroded the outer table of the skull as well as a portion of the inner table. The patient in this case study is documented with photographs, and the entity of pressure due to skin expanders is discussed. A growing list of complications makes it important to be aware of the possible pitfalls of expanders and to discuss them with patients and/or their families, particularly when tissue expanders are used in children.

摘要:

&NA;Advantages and possible complications of combined surgical and interventional radiologic approach to vascular lesions involving the cranial base are presented in three case examples. The methodology and technology of endovascular embolization and occlusion techniques, selection of embolic materials, functional testing to prevent neurologic injury and surgical implications of these treatment modalities are discussed. Emphasis is placed on individualization of each combined approach relative to the aforementioned factors.

摘要:

&NA;The mandibular corpus height, the width measured at the height of the foramina mentale and at a distance of 3 mm from the base, the mandibular corpus length and the mandibular angle were examined in 368 (185 male, 167 female, and 34 uncertain) intact, European anthropologic skulls. The differences between the left and right sides and the two sexes were evaluated. No significant difference was found between the two sides. The differences between males and females did prove statistically significant, but was considered unimportant with regard to the aim of planning a series of mandibular prostheses. The experimental data were broken down into five classes, and the class medians were taken to be the dimensions for the replacements. For a five‐piece series, the relative percentage distribution of the class medians suggests the following proportions for production (&OV0335;—2SD and &OV0335;+2SD 6%, &OV0335;‐SD and &OV0335;+SD 25% and &OV0335;38%). Mandibles with these average dimensions can be chosen from the anthropologic collection, wax models of which may facilitate the planning of a series of mandibular corpus prostheses.
