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.

The management of inadvertent subcutaneous adriamycin infiltration.

Once the inadvertent infiltration of Adriamycin occurs, it is recommended to immediately treat the problem. This has been accomplished by wide excision and meshed split thickness skin grafting for resurfacing of the defect. Obtaining a healed wound alleviates the stiffness from lack of motion or ruptured tendons. Pain from the open ulcer, which is prone to infection in the immunosuppressed patient, is lessened. An analogy between pit viper envenomization and Adriamycin infiltration is discussed.

Mandibular reconstruction and craniofacial fairing.

A method of restoring bony contour defects in the craniofacial regions employing a combination graft of autogenous bone and an alloplastic mesh is presented. Osteoinduction occurs within the confines of the alloplastic mesh from the cancellous bone and the resultant new bone conforms to the outline imposed by the alloplastic device. The advantages of this method include those of alloplastic materials combined with those of bone grafting. There is immediate restoration of an aesthetic contour with adequate strength and sound fixation.

Cranio-orbital correction for massive enlargement of the cranial vault.

A case is reported in which an immense cranial vault was reduced as part of the rehabilitation of a patient with severe hydrocephalus who had preservation of the intellect. This patient was selected carefully, and we do not advocate such procedures on every hydrocephalic. This patient was recumbent and bedridden prior to the procedure because of the size and weight of his head, but he was able to move freely in a wheelchair and attend a special school after the reduction of the skull.

Evaluation of speech after correction of rhinophonia with pushback palatoplasty combined with pharyngeal flap.

A comparison is made of the preoperative and postoperative speech evaluations of 15 selected subjects who had pharyngeal flap operations combined with palatal pushback. Postoperatively, 13 of the 15 patients (86 percent) showed no abnormal nasal emission and no evidence of significant hypernasality during word production. Gross substitution errors were also corrected by the surgical repair. While the number of patients is small, this study indicates equal effectiveness of the surgical technique described--regardless of the sex, the medical diagnosis, whether the procedure was primary or secondary, or the amount of postoperative time--providing there is good function of the muscles of the soft palate.

Current status of biomaterial's clinical applications in plastic and reconstructive surgery.

The use of biomaterials as replacement parts is not new. The concept has fascinated physicians for thousands of years. Using gold plates to reconstruct defects in the skull over 3000 years ago constituted the early record in the literature of use of biomaterials in implantology. The recent advances in space age technology and in clinical biocompatibility has been a major contributing factor in introducing new materials for use as implantology polymers. However, the ideal implant is still not there, and whenever a major reconstruction is required consideration should be given first to the use of autogenous substitutes; when that is not available, then we should resort to inorganic substitutes.

Implantology for correction of cranio-facial defects with an elastomer composite and bone.

The correction of cranio-facial disfigurement in the upper part of the face is the most difficult to achieve. Various materials have been utilized and are still in use. Each has advantages and disadvantages. Autogenous bone has been used with good results, except for the unacceptable irregularities of the forehead and upper orbital region. The combination graft offers the advantages of both: the bone graft will be in contact with the dura, the periorbita and the contaminated sinuses. The polyrane implant produces a smooth and contoured forehead and immediately protects the vital structures during osteoneogenesis. Twenty-six selected patients had this technique used to correct their deformity without any incidence of major complication.

The rejuvenation of the anal sphincteroplasty.

Anal incontinence, as a result of traumatic lesions upon the anal sphincter, is a devastating problem. Direct approximation by appropriate repair may not produce the appropriate animation of the anal sphincter and return of function. The transfer of the gracilis muscle for anal sphincteroplasty, which was initially described for neurogenic dysfunction, is recommended for repair and reconstruction of traumatic and dysfunction. The use of this technique in two patients with anal incontinence following trauma proved to be helpful in alleviating the problems of the patients. A diverting colostomy is used prior to the repair of the anal sphincter. Physical therapy regimens of the reconstructed anal sphincter by the muscle transfer is done prior to closing of the colonic stoma and restoring normal continuity and function of the lower part of the alimentary tract.
