Pediatric Fronto-Orbital Skull Reconstruction.

Craniofacial surgery in children is a highly challenging discipline that requires extensive knowledge of craniofacial anatomy and pathology. Insults to the fronto-orbital skeleton have the potential to inflict significant morbidity and even mortality in patients due to its proximity to the central nervous system. In addition, significant aesthetic and ophthalmologic disturbances frequently accompany these insults. Craniosynostosis, facial trauma, and craniofacial tumors are all pathologies that frequently affect the fronto-orbital region of the craniofacial skeleton in children. While the mechanisms of these pathologies vary greatly, the underlying principles of reconstruction remain the same. Despite the limited data in certain areas of fronto-orbital reconstruction in children, significant innovations have greatly improved its safety and efficacy. It is imperative that further investigations of fronto-orbital reconstruction are undertaken so that craniofacial surgeons may provide optimal care for these patients.

Biodegradable fixation systems in pediatric craniofacial surgery: 10-year experience with 324 patients

Over the past 15 years, resorbable materials have been successfully used for osteosynthesis, but their high cost prevents widespread application. However, the use of resorbable systems could be a method of choice, especially in treatment of children in the active growth period. Obviously, biodegradable materials not only are highly competitive with known metal constructs in terms of fixation rigidity, biocompatibility, and a low risk of infection but also have an undeniable advantage, such as gradual resorption allowing quick return of damaged bones to the physiological conditions of functioning. A special feature of bioresorbable systems is that they can be assembled using ultrasonic welding, which greatly facilitates the fixation process and also provides necessary rigidity, even in cases of joining very thin bones when reliable fixation with screws is impossible. Over the past 10 years, we have used biodegradable systems in 324 patients. In 244 of them, we used traditional (plate/screw) systems; in 80 cases, an ultrasonic welding system was chosen for osteosynthesis. In the present work, we discuss, based on clinical evidence, the advantages and disadvantages of both fixation systems for reconstructive craniofacial surgery in children.

Outcome of craniofacial surgery in children and adolescents with malignant tumors involving the skull base: An international collaborative study

The aim of the study was to characterize the distribution of anterior skull base (ASB) cancers in the pediatric population and to identify predictors of outcome. This was an international study of 1307 patients undergoing craniofacial surgery for malignant tumors; 6.4% (n = 84) among these were <or=21 years old. The most common histologic type was sarcoma (40%), followed by squamous cell carcinoma (14%). Higher incidence of tumors was found in older children (7.5-21 years) compared to younger children. The 5-year disease-specific and overall survival rates were 61% and 55%, respectively (median follow-up of 30 months). The best prognosis was associated with low-grade sarcomas and the worst with salivary and squamous cell carcinomas. High-grade sarcoma represented an intermediate risk group. On multivariate analysis, prior radiotherapy and histology were independent predictors of survival. Surgery for malignant tumors involving the ASB is feasible and safe in children. Histology is significant determinant of poor outcome in this population.

Prospective comparison of methods of closure of the coronal flap after craniofacial surgery in children

The coronal flap in children may be closed with clips or sutures. The results of closure with clips in patients treated during 1 year at the paediatric craniofacial unit, Liverpool, UK, were audited. Eight of 43 required a further general anaesthetic for removal of clips. A prospective audit the following year of patients whose wounds were closed with a rapidly-absorbed polyglactin suture (Vicryl rapide™) showed that 3 out of 39 required re-suture of the wound in theatre (two following trauma from falls). There was one infection in each group. Neither of these patients required formal debridement of the wound in theatre. Rapidly-absorbed polyglactin is a safe alternative to clips for wound closure after craniofacial surgery in children and the morbidity is less because fewer patients have to return to theatre than closure with surgical clips.

Le périoste temporal : étude anatomique et intérêt chirurgical

The periosteum of the temporal area is mentioned at different places in the literature: either against the osseous plane like everywhere in the human body, or between the deep and the superficial temporal fascia. The subperiosteal subtemporal approach in craniofacial surgery in children is in favour of a juxta-osseous localization of the periosteum. Ten premature still-born neonates and two adults cadavers have been dissected for this study and, permit anatomical and histological (with HES coloration) studies. With every specimen, the authors concluded that the temporal periosteum is against the outer table of the calvarium. It became thinner in adults because of direct insertions of the temporalis muscle in the calvaria. An anatomical description of the layers of the temporal area is realised and discussed with an extensive review of the literature. The authors have proposed a subperiosteal subtemporal approach in craniostenosis surgery.

Resorbable osteosynthesis material in craniosynostosis

The results of using resorbable plates and screws (82% polylactic acid and 18% polyglycolic acid) in craniofacial surgery for the correction of craniosynostosis after more than 4 years of experience are presented. Special attention is focussed on the degree of stability and the clinical tissue response to the material employed to answer the question of whether the material is an adequate alternative to titanium. Thirty patients who had been treated with this method for craniosynostoses were examined at regular intervals regarding the shape and stability of the forehead region, visibility and palpability of the plates, and tissue reactions. The technical handling of the osteosynthesis material proved to be simple and reliable. In one case the bone was not strong enough for the screw pitch. After an observation period of a maximum of 4 years and 1 month, the fixations were stable with no signs of adverse reactions. If the long-term results remain favorable, we consider the use of resorbable material a promising method for the stabilization of segments in craniofacial surgery in children.

Infectious Complications of Craniofacial Surgery in Children

During the 10-year period 1975 through 1984, 219 children with congenital anomalies underwent oromaxillary or craniofacial surgery at Children's Medical Center, Dallas. There were no infectious complications following 56 oromaxillary procedures. The overall rate of infection following craniofacial surgery was 14.7% (24 of 163). Infection rates were significantly increased when a combined (monoblock) repair was performed (45% [15 of 33]), compared with either intracranial (8% [six of 72]) or extracranial (5% [three of 58]) procedures alone (P less than .001). The variables identified by multivariate discriminant analysis as useful independent predictors of postoperative infection were, in order of decreasing importance: length of operation, type of procedure (intracranial, extracranial, or combined), and age. Staged procedures are recommended for craniofacial surgery whenever possible because of the significant increase in rate of infection associated with the monoblock repair.

Psychosocial outcome of craniofacial surgery in children.

Thirty-four children between the ages of 7 and 15 years with congenital craniofacial anomalies underwent psychosocial evaluation before and 12 to 18 months after surgery. Also evaluated were healthy children matched to the craniofacial subjects by sex, age, intelligence, and economic background. Preoperative assessment revealed the craniofacial group to have multiple but not severe psychosocial limitations. At follow-up, only a measure of social functioning still differentiated the groups, with the craniofacial subjects experiencing more negative social encounters. Comparison of initial and follow-up scores for the craniofacial group revealed a significant reduction in trait anxiety and trends toward reduction in parent-reported inhibited and hyperactive behavior. Scores on measures of extraversion and social functioning tended to be positively correlated with age for the comparison subjects only. Results suggest a modest improvement in psychological adjustment following surgery with a residual, possibly increasing, deficit in social functioning.

Craniofacial Surgery in Children: Concepts and Questions

Craniofacial surgery is an exciting new subspecialty of medicine. It is strictly a team project that will function well only in a tertiary medical center. Particular coordination is needed among the plastic surgeon, neurosurgeon, anesthesiologist, and pediatrician. This article considers many of the potential advantages and some of the disadvantages of performing craniofacial surgery on infants. It is difficult or impossible, based on current knowledge, to predict the ultimate limits of such new techniques. The history of surgical evolution, however, continues to demonstrate that what "at first observation" was thought to be impossible or undesirable often evolves, with more understanding, to be the desired course of action. It was entirely appropriate that the initial craniofacial surgical efforts be generally confined to adult-type patients, but the currently available technical refinements have developed such procedures to the point where they now have a definite place in infant surgery as well. Continued clinical investigative research will provide further information regarding the eventual benefits and perhaps will lead to surgical techniques in neonates that will actually prevent the development of certain predictable deformities.
