Post-operative re-construction of dentoalveolar tissue and the mandible and maxillae using prosthetic therapy.

OBJECTIVE: To determine the range of ablative surgery and rehabilitative procedures performed on maxillofacial structures. DESIGN: A retrospective descriptive study. SETTING: University of Nairobi Dental Teaching Hospital. SUBJECTS: Patients operated on at the institutions theatre, and followed up at the University of Nairobi Dental Teaching Hospital Oral Surgery Outpatient Clinic during the period February 1996, August 1998. RESULTS: Forty four patients underwent ablative surgery during the study period. Complete records were available for 38 patients, 27 females and 11 males aged 10 to 79 years (mean 32.6 years). Surgical procedures performed included: partial mandibulectomy, marginal mandibular resection, subtotal maxillectomy, sequestrectomy and enucleation. Six (15.8%) patients who underwent mandibular resection had rigid bone plating. Five (13.2%) patients who had maxillary involvement were given surgical obturators post-operatively with one receiving a complete denture after full recovery. A total of 22 (57.9%) patients who would have reaped benefits from prostheses therapy received none. Individual patient follow-up periods ranged from seven days for two patients who had cyst enucleation to two years for three cases with ameloblastoma, and two cases with squamous cell carcinoma. CONCLUSION: It is concluded that prosthetic rehabilitation of patients undergoing extensive surgery at the University of Nairobi Dental Teaching Hospital is largely inadequate.

[Synthesis and evaluation of the clinical approach to growth].

A critical reflection based on literature is presented to the lectures given at the symposium "A clinical approach to growth" at the 73rd Réunion Scientifique of the Société Française d'Orthopédie Dento-Faciale in Deauville, France, on may 13th, 2000. Uncertainty is expressed about the long-term effects on the growth pattern after early surgery in children. It is apparent that conventional dentofacial orthopedics have a limited long-term effect on the growth pattern. Surgical as well as non-surgical (orthopedic) approaches are plagued by complications and relapse. The need for unbiased clinical research and standardized, complete documentation and analysis--also on how/why clinical decisions were taken--seems of utmost importance for a balanced future development of conventional and newly introduced techniques.

[Early orthodontic treatment, a diagnostic challenge].

This article investigates which growth anomalies require early orthodontic interception, that is before the age of 9 years. The diagnosis should be established at three levels: the skeletal jaw relationship including the facial profile, dental space problems determined by the apical base area, and function. Rather than to advise on mechanotherapy emphasis is placed on improvement of diagnostic skills because, contrary to therapy, making a diagnosis cannot be delegated. The analysis at the three diagnostic levels shows that only a limited number of situations demand early treatment. Among these are a negative overjet, a cross-bite, open mouth posture, and sometimes a space maintainer after extraction of deciduous molars. Special precautions are required when front teeth become ankylosed at an early age after trauma. In case of doubt the general practitioner is advised to seek orthodontic counseling from a specialist.

An 8-year assessment of maxillofacial prosthetic patients treated in a Department of Prosthetic Dentistry.

The Department of Prosthetic Dentistry at the University of the Witwatersrand, Johannesburg, serves as a referral centre for maxillofacial prosthetic patients from the surrounding general hospitals and local private clinics. This places a time and financial constraint on the department. The aim of this study was to establish the number of new patients seen annually, the causative factors associated with the various types of defects, the treatment provided and the cost per patient in terms of clinical hours and prosthesis fees. The data were taken from the records of patients treated in the maxillofacial prosthetics clinic during an 8-year period, from January 1991 to December 1998. The total number of new patients was calculated and the data were collated according to the year in which treatment commenced. Results were tabulated according to the number of new cases in each group, the aetiology of the defects, prosthetic treatment provided and the costs in terms of clinical hours and prostheses. The results of this study indicate that there is a need for a specialised Maxillofacial Prosthetic Unit. Although the present fee schedule needs to be revised, there is still a need for a substantial amount of state subsidy.

[Oligodontia. A case report].

"Oligodontia" is the absence of 6 or more teeth, except the third molars. Genetic factors are important in determining hypodontia: in fact, this is an autosomal dominant trait relatively common in population. In particular, the agenesis of lateral incisors is fairly common, with autosomal dominant and variable expression inheritance. The incidence of hypodontia in primary dentition is 0.1-0.7% and there is no difference between females and males; instead, hypodontia in permanent dentition is most common in females compared with males and the incidence is 6-10% in general population. Oligodontia can interfere with the maxillofacial skeleton growth in children and adolescents. This problem must be tackled by paying attention to the physical and psychological development of the patient. A case of oligodontia in an 8-year-old-boy without 17 permanent teeth likely related to a variable expression genetic disorder is reported. The medical examination of the boy was completely negative, with the exception of the dentition. The child will be followed to value any possible maxillofacial abnormalities that might need an early therapy. The definitive therapeutic approach will be carried out, as soon as possible, using oral endo-osseous systems to allow normal masticatory and phonetic function.

[Surgical orthodontic technique for the treatment of maxillofacial deformities and dysfunction of occlusion after maxillofacial fractures].

OBJECTIVE: To evaluate a new technique to treat severe maxillofacial deformity and dysfunction of occlusion after the maxillofacial fractures. METHODS: Thirty-four consecutive patients, with delayed maxillofacial deformities and dysfunction of occlusion after the maxillofacial fractures, were treated by the use of x-ray cephalometric analysis, model surgery, open reduction and rigid internal fixation. RESULTS: Thirty-three patients were successfully corrected the maxillofacial deformities, facilitated normal occlusal relationship. Only one patient with severe damage of the brain was presented a mild occlusion dysfunction one year after the operation. CONCLUSIONS: The above-mentioned technique may be a viable and effective option for the management of the deformities of the face and dentition after the maxillofacial fractures.

[Retention and rehabilitation of complex maxillofacial defects based on bar-clip and stud attachment].

PURPOSE: To evaluate the application of precise attachment in restoration of complicated maxillofacial defect. METHODS: A framework with bar-clip and stud attachment was designed and fabricated. Maxillofacial prosthesis with this framework was applied to treat a patient with defects of nose, entire upper lip and the corresponding maxillofacial areas. The retention force was tested with Universal Testing Device. RESULTS: After treatment, the patient got a better appearance, normal function of mastication and clear pronunciation. The dislodgement test showed the retention force was 40N. CONCLUSION: Application of precise attachment in complicated maxillofacial defects can get satisfactory result.

[Diagnostic value of multi-slice spiral CT three dimensional reconstruction in maxillofacial diseases].

OBJECTIVE: To evaluate the diagnostic value of multi-slice spiral CT (MSCT) three dimensional (3D) reconstruction for maxillofacial diseases. METHODS: Sixty patients with maxillofacial diseases underwent the scanning of MSCT with 3D reconstruction. Among them, 34 patients with maxillofacial fracture, 10 patients with maxillofacial tumors and tumor-like diseases, and 16 patients with congenital deformities. The MSCT scanned with slice thickness of 2 mm. The methods of 3D reconstruction included multi-planar reconstruction (MPR), shaded surface display (SSD), and volume rendering (VR). The results were compared with what was observed during operations. RESULTS: Totally 36 cases of maxillofacial fracture were shown by 2D or 3D imaging and were validated by the observations during operation. The MSCT with 3D reconstruction imaging was significantly superior to 2D axial imaging in maxillofacial fracture. Three dimensional imaging could clearly show the spacial anatomy of facial, fragment displacement, and tracing fracture lines. However, 2D imaging had better effectiveness than 3D imaging in observing deep structure and fine fracture. In maxillofacial tumors and tumor-like diseases, 3D imaging was significantly superior to 2D axial imaging in showing the tumor shape and spacial relationships between tumors and surrounding structures. Two dimensional imaging and MPR imaging were excellent to reveal internal structure and pathological changes of tumors. 2D imaging and MPR imaging also achieved better results in showing tumors extended to soft tissues. In maxillofacial congenital deformities, 3D imaging were superior than 2D imaging. CONCLUSION: 3D imaging has an important value in the diagnosis and clinical assessment of maxillofacial fracture, tumor-like diseases, and congenital deformities.

[Transtracheal jet pulmonary ventilation as a measure for preventing hypoxia during reconstructive maxillofacial operations].

Anesthesia including high- or low-frequency transtracheal jet ventilation of the lungs was used in 52 patients with maxillofacial abnormalities subjected to repair surgery. The number of respiratory cycles was 20 per min in 1 group and 120 per min in the other. Intubation of the trachea was started 20 min after ventilation was started. Transtracheal jet ventilation of the lungs prevented hypoxia during intubation of the trachea in such patients. High-frequency jet ventilation of the lungs may be a method of choice in such cases.

[Maxillofacial and dental abnormalities in some multiple abnormality syndromes. "Cri du chat" syndrome, Wilms' tumor-aniridia syndrome; Sotos syndrome; Goldenhar syndrome].

The paper describes the maxillo-facial and dental anomalies observed in some chromosome and non-chromosome poly-malformative syndromes ("Cri du chat" syndrome; Wilms' tumour; Sotos' syndrome; Goldenhar's syndrome). The Authors emphasise the possibility of diagnosing these multiple deformity syndromes from maxillo-facial alterations in early infancy; anomalous tooth position and structure cal also be successfully treated immediately after the first appearance of teeth. This is a particularly promising field of pediatrics and preventive pediatric medicine.

Morphologic characteristics of masseter muscle in cleidocranial dysplasia: a report of 3 cases.

Cleidocranial dysplasia (CCD) is a rare autosomal dominant skeletal dysplasia. In order to define the morphologic characteristics of the masseter muscle incidental to bone abnormalities, we present 3 cases of CCD with the masseter muscle thickness and maxillofacial bone abnormalities, using computed tomography (CT) and panoramic radiographs. In CCD patients (a) the masseter muscles were less thick than in age- and sex-matched control subjects, (b) the zygomatic arch was discontinuous with the hypoplastic zygomatic bone, (c) the ascending ramus of the mandible had parallel-sided borders, and (d) the coronoid process pointed upwards and/or posteriorly. We have concluded the masseter muscles are less thick than normal, alongside the maxillofacial bone abnormalities in CCD patients.

[Facial developmental irregularities of the face- in children with Binder's syndrome with regard to indirect angular measurements].

UNLABELLED: Binder's syndrome is a disorder characterised by the underdevelopment of maxilla and nose. PURPOSE: The paper presents an attempt to analyse the developmental irregularities, described by angular features in patients with the syndrome. PATIENTS AND METHODS: The research was performed on 4 children aged 5-12 with maxillonasal dysplasia. Before orthodontic and surgical treatment standardised photographs of the head -- anterior and lateral (right and left) were taken. Seven angular measurements were taken on the standardised lateral photographs. The same measurements were made in the group of 30 girls and 60 boys aged 5-12 years. THE RESULTS of measurements were normalized into means and standard deviation of analogous features for normal persons in groups of sex and age, then every angle of the face was counted. From all angular features, three (fronto-nasal angle, inclination of upper lip angle and inclination of chin angle) were characterised by higher means in children with maxillonasal dysplasia. The most favourable mean of normalised value referred to the fronto-nasal angle and was 2.9. CONCLUSIONS: On the basis of this analysis it was affirmed that people with Binder's syndrome are characterised by a flat nose and strong inclination of upper lip and chin, resulting in characteristic concave facial profile. The most visible malformations of the face concern the inclination of the nose. The smallest deviation is localised in the area of the nose and lips.
