Maternal discourse features used with language-normal preschoolers with facial deformities.

Discourse features of 10 mothers of language-normal preschool children with repaired cleft palates were examined. Mothers had been provided training in infant stimulation. Fifty-six percent of the communication initiations within the mother-child dyads were made by the mothers. That level of responsibility for continuity of communication resembles the percentage of discourse initiation reported for mothers of language-normal children without orofacial clefts. All categories of utterance types were used by the subjects; a predominance was found among attention-getters and indirect directives. Distribution of discourse features appears to differ from that reported for mothers of both language-normal and language-impaired children who do not have orofacial clefts.

A quick technique for harvesting cranial bone grafts.

A simple technique is presented for quick harvesting of cranial bone in patients who require limited amounts of bone to cover defects in the craniofacial area. The major principle involved is to stay within the same anatomical region. For bigger defects, larger incisions and different techniques are usually used.

Reconstruction of a large congenital cranioorbital defect with a species-specific demineralized bone implant.

Bone grafting is one of the most common operative procedures in craniofacial surgery today. Almost all surgical defects have to be closed with a graft, and all stabilized segments require bone grafts for stabilization prior to fixation. In certain circumstances, however, lack of availability of large grafts necessitates the use of bone substitutes. In the patient presented, a large defect--which is larger than a critical size defect--did not close on its own, even though neonates have a very high potential for forming bone around the dura. The defect was closed with demineralized bone implantation and showed complete filling of the defect through the bone induction principle.

Congenital lipofibromatosis associated with macrodactyly of the foot.

Congenital lipofibromatosis of the foot, a type of paracrine growth disorder, is a distinct clinical entity that must be differentiated from other causes of macrodactyly, with specific diagnostic and therapeutic considerations. Eleven skeletally immature patients with congenital lipofibromatosis and macrodactyly of the foot were studied. Diagnostic histopathologic criteria were documented. The most specific pathologic finding of congenital lipofibromatosis is an overabundance of fibrofatty tissue on the plantar aspect of the foot and involved toes. Surgical defatting or debulking procedures, ray resection, and phalangeal epiphysiodesis produced significant cosmetic improvement. Syndactylization and phalangeal resection were not as beneficial.

Effect of Ringer's lactate irrigation on the formation of postoperative abdominal adhesions.

Intraabdominal adhesions continue to pose a potentially serious postoperative clinical problem. Reported here is an experiment designed to study any effect that balanced Ringer's lactate (RL) solution may have on intraabdominal adhesion formation. Surgical trauma was induced in mice by controlled gauze abrasion of one side of the abdominal wall; the opposite side was used as a control. RL irrigation was compared with no irrigation. Adhesions were scored on the basis of incidence (%) and severity (on a 0-10 scale). The abraded right peritoneum exhibited 100% adhesions for both the RL group and the nonirrigated group. However, on the side that was not abraded, the nonirrigated group showed only 30% incidence of adhesions and 1.7 +/- 3.3 severity as compared with 100% adhesions and 7.7 +/- 2.2 severity for the RL group. These results suggest the need for further studies to establish the extent to which irrigation with solutions such as Ringer's lactate or saline may enhance formation of postoperative adhesions.

Psychological aspects of parents of children with craniofacial anomalies.

Parents of 27 children with pure craniosynostosis seen at a craniofacial clinic were surveyed to measure variables associated with family psychological stress. Each parent was asked to complete the Questionnaire on Resources and Stress and to provide information on various family and demographic characteristics. The level of psychological stress was positively associated with the number of older children in the home, not having one's own car, and not having prior experience caring for a handicapped person. Having someone to help care for one's child was also positively associated with family stress level. The level of family stress was negatively associated with the respondent's current health and degree of satisfaction with the amount of time clinic staff spent with one's child. These findings suggest a means of identifying families at high risk for stress associated with having a child with a craniofacial disorder who may need supportive services.

Aesthetics of feminizing the male face by craniofacial contouring of the facial bones.

The "forceful" and macho look of a prototypical man may not be unduly appealing to others whom he meets. This "forceful" look might not even appeal to the individual himself. In order to soften this appearance, a series of operative procedures has been devised for use on the craniofacial skeleton. These surgical steps can be done in a single operation or as a series of multiple operative procedures. Moreover, the needs of some patients may require that only special segments of these procedures be performed. This article presents these operative procedures and describes the feasibility with which they can be performed. Complications and unfavorable outcomes, when they occur, are usually related to unrealistic expectations on the part of the patient. The surgical steps routinely performed are those that contour the forehead, orbits, malar eminence, cheeks, chin, angle of the mandible, and larynx. Three categories of patients are described: the female with a male face; the male with a "forceful look"; and the patient requesting a gender identity change. The psychosocial, psychological, and behavioral problems leading to the decision for surgery will be the basis of final patient selection.

Involvement of the thymus and cellular immune system in craniofacial malformation syndromes.

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, cranio-synostosis 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, and Staphylococcus aureus mitogens. 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.

Bone grafting for cranial reconstruction.

Precise reconstruction of defects of facial bones including the neurocranium is now possible with the use of CAD/CAM technology and biomaterials, such as OsteoMesh, combined with bone grafting.
