Motivation for starting treatment and satisfaction with treatment results were evaluated on the basis of replies to a 14-item questionnaire and clinical examination of 28 orthognathic patients from 6 months to 2 years after treatment. The most common reasons for seeking professional help were problems in biting and chewing (68 per cent). Another major reason was dissatisfaction with facial appearance (36 per cent). Many patients also complained of temporomandibular joint symptoms (32 per cent) and headache (32 per cent). Women (8/19) were more often dissatisfied with their facial appearance than men (2/9), but the difference was not statistically significant. In agreement with earlier studies, the results of orthognathic treatment fulfilled the expectations of almost every patient. Nearly 100 per cent of the patients (27/28) were satisfied with treatment results, although 40 per cent experienced some degree of numbness in the lips and/or jaw 1 year post-operatively. The most satisfied patients were those who stated temporomandibular disorders as the main reason for seeking treatment and whose PAR-index had improved greatly. The majority of the patients experienced the orthodontic treatment as painful and as the most unpleasant part of the whole treatment, but all the patients were satisfied with the pre-treatment information they were given on orthodontics. Orthodontic-surgical therapy should be of a high professional standard technically, but the psychological aspects are equally important in the treatment protocol. The professionals should make efforts to understand the patient's motivations for and expectations of treatment. Patients should be well prepared for surgery and supported for a long time after to help them to adjust to post-surgical changes. 相似文献

This retrospective epidemiological study was undertaken to assess factors related to adult orthodontic treatment and to identify any associated trends. Case records of all patients (676) aged 18 years or over at the start of active orthodontic treatment at the Eastman Dental Hospital, London were examined. Variables associated with patients and their treatment (age, sex, source of referral, malocclusion, type of appliance, and interdisciplinary treatment including orthognathic surgery) were studied and the data analysed statistically. Findings revealed that the number of adult patients undergoing orthodontic treatment has increased significantly, especially since 1985. The age of the patients treated was also found to increase in recent years. The percentage of female patients (72 per cent) Class III malocclusions (21.6 per cent) and Class III skeletal bases (26.2 per cent) was higher than found in studies on children. Most of the treatments required fixed appliances and over half involved interdisciplinary treatment, with an increase in the percentage of orthognathic surgical cases. Surgery was significantly more common in males (P less than 0.01) and highly significantly associated with Class III malocclusions and skeletal III bases (P less than 0.001). Twenty-five per cent of adult patients were found to have had a previous course of orthodontic treatment though these patients were not significantly different from adult patients presenting for the first course of treatment. 相似文献

This study was conducted in Turkish female patients to investigate their preoperative concerns, motivation, expectations, preoperative preparation for surgery and perception of outcomes concerning orthognathic surgery. Thirty women, with an age range of 18 to 31 years (mean age 21.8+/-3.8 years), participated in the study. The expectations and the results of orthognathic treatment were assessed based on the patients' subjective appraisal. Patients completed questionnaires before and after the operations, designed to investigate the preoperative and postoperative psychological impact of the surgery, the perception of problems with physical and psychological functioning, self-image, body image and satisfaction with surgical outcome. The questionnaires were evaluated statistically with SPSS 11.5 for Windows. The patients' perception of their psychological improvement, faith in the surgical team, physical functioning, self-esteem, social confidence, body image and satisfaction after dentofacial correction were higher than the preoperative levels. The conclusions of the study support the theory that enhancement of facial appearance by orthognathic surgery improves the psychological status of females with growth disturbances of the jaw. 相似文献

Temporomandibular dysfunction in patients treated with orthodontics in combination with orthognathic surgery 总被引:3,自引:0,他引:3
Fifty-two patients with malocclusions underwent orthodontic treatment in combination with orthognathic surgery involving a Le Fort I and/or sagittal split osteotomy. Approximately 5 years after surgery, the patients were examined for signs and symptoms of temporomandibular disorders (TMD). The frequencies were found to be low in comparison with epidemiological studies in this field. The aesthetic outcome and chewing ability were improved in most patients (about 80 per cent). Some of the patients had reported recurrent and daily headaches before treatment. At examination, only two patients had reported having a headache once or twice a week, while all the others suffered from headaches less often or had no headache at all. Eighty-three per cent of the patients reported that they would be prepared to undergo the orthodontic/surgical treatment again with their present knowledge of the procedure. This study shows that orthodontic/surgical treatment of malocclusions not only has a beneficial effect on the aesthetic appearance and chewing ability, but also results in an improvement in signs and symptoms of TMD, including headaches. 相似文献

Objective:To examine the current trends in surgical-orthodontic treatment for patients with Class III malocclusion using time-series analysis.Materials and Methods:The records of 2994 consecutive patients who underwent orthognathic surgery from January 1, 2004, through December 31, 2015, at Seoul National University Dental Hospital, Seoul, Korea, were reviewed. Clinical data from each surgical and orthodontic treatment record included patient''s sex, age at the time of surgery, malocclusion classification, type of orthognathic surgical procedure, place where the orthodontic treatment was performed, orthodontic treatment modality, and time elapsed for pre- and postoperative orthodontic treatment.Results:Out of the orthognathic surgery patients, 86% had Class III malocclusion. Among them, two-jaw surgeries have become by far the most common orthognathic surgical treatment these days. The age at the time of surgery and the number of new patients had seasonal variations, which demonstrated opposing patterns. There was neither positive nor negative correlation between pre- and postoperative orthodontic treatment time. Elapsed orthodontic treatment time for both before and after Class III orthognathic surgeries has been decreasing over the years.Conclusion:Results of the time series analysis might provide clinicians with some insights into current surgical and orthodontic management. 相似文献

This paper reviews the literature about the most relevant complications in daily orthognathic surgery. Although orthognathic surgery has proven to be relatively safe, patients who undergo such maxillofacial orthopaedic surgery must be aware of the side effects of this combined treatment. Immediate life-threatening complications are very rare. They can in most cases be avoided by good anaesthetic and surgical techniques and adequate postoperative care. The most frequently encountered perioperative problem in maxillary surgery is excessive blood loss, whilst subjective neurosensory disturbance is the most frequent complication in mandibular surgery. Good co-operation between orthodontist and surgeon is essential to prevent most immediate and late postoperative problems and nearly all unsatisfactory results. 相似文献

PURPOSE: Steroid hormones are therapeutic for motor and/or sensory dysfunctions caused by nerve injury. However, the timing for giving such medicine is unclear. This study aimed to estimate the efficacy of steroid treatment and determine an appropriate start time after sensory impairment. PATIENTS AND METHODS: Twenty-seven patients with sensory impairment who received orthognathic surgery were classified into groups called 1W (n = 6), 3W (n = 6), or 6W (n = 8) group on the basis of start time for steroid treatment, being 1 week, 3 weeks, or 6 weeks after surgery, respectively, and a no steroid treatment (NST) group (a control group) (n = 6) that did not receive treatment for 10 to 12 weeks after surgery. Sensory impairment was diagnosed if postoperative first week mechanical-touch threshold was over 4.0 as measured by Semmes aesthesiometer. Prednisolone treatment was administered orally to patients at 30 mg for 7 days, 15 mg for 4 days, and 5 mg for 3 days. Mechanical-touch threshold and thermal perceptions were compared before and after treatment. RESULTS: At 1 week postoperatively, there were no significant differences in mechanical-touch threshold among the 4 groups (analysis of variance, P >.05). Changes in mechanical-touch threshold in the 1W group showed no significant improvement (analysis of variance, P >.05), but in the 3W and 6W groups, there were significant differences compared with the NST group (Dunns methods, P <.05). CONCLUSIONS: Steroid treatment for sensory impairment after orthognathic surgery has the potential to accelerate recovery and it appears desirable to start treatment later than 1 week postoperatively. 相似文献

This multicentre, retrospective, study assessed the cost, and factors influencing the cost, of combined orthodontic and surgical treatment for dentofacial deformity. The sample, from a single region in England, comprised 352 subjects treated in 11 hospital orthodontic units who underwent orthognathic surgery between 1 January 1995 and 31 March 2000. Statistical analysis of the data was undertaken using non-parametric tests (Spearman and Wilcoxon signed rank). The average total treatment cost for the tax year from 6 April 2000 to 5 April 2001 was euro6360.19, with costs ranging from euro3835.90 to euro12 150.55. The average operating theatre cost was euro2189.54 and the average inpatient care (including the cost of the intensive care unit and ward stay) was euro1455.20. Joint clinic costs comprised, on average, 10 per cent of the total cost, whereas appointments in other specialities, apart from orthodontics, comprised 2 per cent of the total costs. Differences in the observed costings between the units were unexplained but may reflect surgical difficulties, differences in clinical practice, or efficiency of patient care. These indicators need to be considered in future outcome studies for orthognathic patients. 相似文献

AbstractObjective: To collect information on the current consent practices of consultant orthodontists for orthodontic and joint orthognathic treatment.Design: Postal questionnaire.Subjects and Methods: The questionnaire was sent to all 222 consultant orthodontists held on the database of the British Orthodontic Society. The questionnaire consisted of five multi-part questions requiring tick-box responses.Outcome: A total of 199 questionnaires were returned.Results: Written information on orthodontic treatment was provided by 56 per cent of respondents whilst 41 per cent obtained written consent. Written information on joint orthognathic treatment was provided by 47.5 per cent of respondents, whilst 20 per cent obtained joint written consent. Most who obtained written consent for orthodontics and joint orthognathic treatment used 16 years as an appropriate age for patients to provide their own consent.Conclusions: Consent practice amongst consultant orthodontists varies, with 35 per cent providing neither written information nor seeking written consent prior to orthodontic or joint orthognathic treatment. 相似文献

The aim of this study was to determine which of two occlusal indices were the most appropriate for use in the assessment of orthognathic outcome. The indices used were the Peer Assessment Rating (PAR) Index and the Index of Treatment Complexity, Outcome, and Need (ICON). These indices were validated against the subjective assessments of treatment outcome and treatment improvement obtained from a panel of experienced orthodontic consultants. For the subjective assessment, intraexaminer agreement for ranking treatment outcome, from patient study models (30 models), was good. Interexaminer agreement for ranking treatment outcome, in the same way, was good or moderate. Intraexaminer agreement for ranking treatment improvement (30 start and finish pairs of models) was very good or good. Interexaminer agreement for ranking treatment improvement ranged from good to fair. All the patient study models were scored using PAR and ICON. The level of correlation between PAR and ICON scores of treatment outcome and the subjective ranking of treatment outcome was significant (P < 0.001). The level of correlation between PAR and ICON scores of treatment improvement and the subjective ranking of treatment improvement was also significant (P < 0.001). It is concluded that both PAR and ICON are suitable indices for assessing the clinical outcome of combined orthodontic treatment and orthognathic surgery. 相似文献

Tongue-lip adhesion can be effective in relieving tongue-based airway obstruction in the neonatal period. However, longitudinal evaluation of these patients demonstrates they require additional procedures for ultimate control of their airway, feeding, and orthognathic relationship. Charts of patients with Pierre Robin sequence who underwent unsuccessful nonoperative treatment and tongue-lip adhesion procedures by the senior author between 1989 to 1999 were reviewed. In particular, secondary interventions were quantified and qualified to determine if tongue-lip adhesion was a definitive treatment of the pathology caused by this sequence. Eleven patients with ages ranging from 2 to 6 weeks underwent initial tongue-lip adhesion. Seven patients were syndromic (3 Stickler's, 1 Goldenhar's, 1 Fragile X, 1 Miller's, 1 chromosome 15 rearrangement), and four had isolated Pierre Robin sequence. Two patients had dehiscence of their initial repair within 2 weeks, for a primary surgical success rate of 82%, consistent with other published reports. A detailed follow-up of these patients revealed that 10 of 11 (91%) required additional intervention for airway or feeding issues. Of those requiring secondary intervention, an additional 1.9 secondary procedures were performed per patient to achieve control of the airway, feeding, and orthognathic problems. More than half of the patients needed gastrostomy tubes to overcome feeding difficulties. Five patients necessitated secondary surgery for recurrent airway obstruction within 4 months of the initial surgical treatment (four distractions and one repeat tongue-lip adhesion). Four others required distraction at an older age for orthognathic indications. Two patients were successfully treated with tongue-lip adhesion only. Tongue-lip adhesion has a high initial success rate for correction of neonatal airway obstruction. However, long-term follow-up indicates a high incidence of secondary intervention requirements. In retrospect, perhaps tongue-lip adhesion should be considered a temporizing procedure for most patients with Pierre Robin sequence. 相似文献

The purpose of this study was to compare the treatment outcome and long-term stability of 2 groups of young adult patients diagnosed with active condylar hyperplasia and treated with 2 different surgical methods. Thirty-seven patients (19 females and 18 males) met the criteria for inclusion in the study. Group 1 (n = 12; average age at surgery, 17.5 years) was treated with orthognathic surgery only, while group 2 (n = 25; average age at surgery, 16.7 years) had high condylectomy, articular disc repositioning, and orthognathic surgery. All patients underwent standardized clinical and radiographic examination at initial consultation, immediately before surgery, immediately after surgery, and at longest follow-up. Objective evaluation of temporomandibular joint (TMJ) function included maximum incisal opening and lateral excursions. Subjective evaluations were performed in group 2 for TMJ pain, jaw function, and diet. Lateral cephalometric radiographs were evaluated for presurgical and postsurgical mandibular growth. There were no statistically significant differences (P >.05) between the 2 groups for maximal incisal opening, lateral excursions, or subjective jaw function before surgery. Presurgical growth differed significantly (P <.05), with group 2 showing more active growth. At the long-term follow-up, no differences were found in lateral excursions or subjective jaw function. There was a statistically significant difference in maximum incisal opening (P <.01), with a greater increase in group 2, as well as a statistically significant difference (P <.05) in cephalometric stability, with group 2 being much more stable at long-term follow-up. All patients in group 1 grew back into skeletal and occlusal Class III relationships and required secondary intervention. Only 1 patient in group 2 required secondary surgery, involving maxillary surgery to correct postsurgical transverse maxillary relapse; the mandible was stable at long-term follow-up. The results of this study showed that patients with active condylar hyperplasia treated with high condylectomy, articular disc repositioning, and orthognathic surgery have stable, predictable outcomes compared with those treated with orthognathic surgery alone. 相似文献

The aim of this multi-centre retrospective study was to assess the cost, and factors influencing the cost, of combined orthodontic and surgical treatment for dentofacial deformity. The sample, from the south-west of England, comprised 352 subjects (109 males and 243 females) with an age range of 14 to 57 years treated in 11 hospital orthodontic units. Treatment costs were calculated for each subject by combining consumable costs with staff overhead and capital costs. The median total treatment cost was euro 6075.25 (interquartile range: euro 5139.41-euro 7069.68). Out-patient costs comprised 43 per cent. The median orthodontic treatment costs were euro 1456.23 (interquartile range: euro 1283.73-euro 1638.75). Orthodontic costs on average comprised 25 per cent of the total treatment cost. The cost of orthodontics for orthognathic patients in a hospital setting appears to represent excellent value for the state funded National Health Service in the United Kingdom. 相似文献

A longitudinal study was conducted of the psychologic characteristics of 74 persons undergoing orthognathic surgery. The effects of neuroticism, locus of control, and expectations upon post-surgical outcomes were examined. The majority of patients scored in the normal range of most personality variables. The findings suggest a generally intact ego and accurate self-concept among orthognathic surgery patients. Expectations of pain and parasthesia were the best predictors of postsurgical outcomes, while neuroticism and locus of control scores predicted some outcomes in the early post-operative stages. The results indicate the importance of preparing orthognathic surgery patients against unrealistic expectations before surgery is undertaken, and of counseling certain patients during the early postoperative period. 相似文献

The purpose of this prospective, randomized, double blind study was to assess the effect of tranexamic acid on blood loss, quality of surgical field and duration of surgery in adolescent orthognathic surgery patients. 50 consecutive patients, scheduled for orthognathic surgery were included. The study group (n=25) received tranexamic acid 10mg/kg as a bolus preoperatively followed by 1mg/kg as a maintenance dose intra operatively; the control group (n=25) received placebo (normal saline). All patients received moderate hypotensive anaesthesia with nitroglycerin and had surgery according to a standard protocol. Intra operative blood loss, duration of surgery, quality of surgical field, blood transfusion and complications, if any, were recorded. The mean total blood loss was 166.1±65.49ml in the study group and 256.4±77.80ml in the control group. The results showed statistically significant reduction in blood loss (p<0.001) and improved quality of surgical field (p<0.001) in the study group. There was no significant difference in duration of surgery and transfusion requirements between the two groups. In conclusion, preoperative and intra operative administration of the antifibrinolytic agent, tranexamic acid, is effective in controlling blood loss and improving the quality of the surgical field. 相似文献

Human jaw dysmorphologies are frequent and often affect young patients, resulting in malocclusion of teeth and inappropriate jaw relationships. Treatment is performed by means of orthodontics with orthognathic surgery as required. Mandibular asymmetry is one of the most frequent dysmorphologies, but in many cases, the specific cause is unknown.In healthy patients who were undergoing orthognathic surgery for correction of malocclusion, we tested the hypothesis that masseter muscle phenotype composition, which determines contractile properties, was different between sides in patients with mandibular asymmetry but not in those without mandibular asymmetry. After cephalometric analysis, 50 patients from whom we obtained samples of both right and left masseter muscles were separated into 2 groups: with or without mandibular lateral deviation. Samples were immunostained with myosin-isoform-specific antibodies to identify 4 skeletal muscle fiber types, and their fiber areas and proportions were measured. Two-tailed Wilcoxon test for paired samples was used to compare the 4 fiber-type compositions by means of percent occupancy and mean fiber area on both sides. Patients with mandibular asymmetry were associated with a significant increase of type II fiber occupancy (P = 0.0035) on the same side as the deviation. This finding that masseter muscle phenotype is significantly linked to mandibular asymmetry is of relevance to physiotherapeutic and surgical managements of jaw discrepancies and merits further investigation in the light of its possible role in the etiology of this condition. 相似文献

Severe midface hypoplasia in patients with various craniofacial anomalies can be corrected with Le Fort III or monobloc advancement. Often additional corrective orthognathic surgery is indicated to achieve Class I occlusion and a normal inter-jaw relationship. This study evaluated the incidence of, and the surgical indications for, secondary orthognathic surgery following Le Fort III/monobloc advancement. The total study group consisted of 41 patients: 36 patients with Le Fort III advancement and 5 patients with monobloc advancement. Seven patients underwent additional orthognathic surgery. Of the resulting 18 non-operated patients older than 18 years at the end of follow-up, Class I occlusion was observed in 11 patients. In the remaining patients malocclusions were dentally compensated with orthodontic treatment. None of the patients was scheduled for additional orthognathic surgery due to the absence of functional complaints and/or resistance to additional surgery. Le Fort III and monobloc advancement aim to correct skeletal deformities on the level of zygoma, orbits, nasal area and forehead, but Class I occlusion is frequently not achieved. Additional orthognathic surgery is often indicated in patients undergoing Le Fort III or monobloc advancement. Naso-endoscopic analysis of the upper airway and the outcomes of sleep studies may influence the orthognathic treatment plan. 相似文献

In a retrospective multicentre study, the success rate and efficiency of activator treatment were analysed. All patients from two University clinics (Giessen, Germany and Berne, Switzerland) that fulfilled the selection criteria (Class II division 1 malocclusion, activator treatment, no aplasia, no extraction of permanent teeth, no syndromes, no previous orthodontic treatment except transverse maxillary expansion, full available records) were included in the study. The subject material amounted to 222 patients with a mean age of 10.6 years. Patient records, lateral head films, and dental casts were evaluated. Treatment was classified as successful if the molar relationship improved by at least half to three-fourths cusp width depending on whether or not the leeway space was used during treatment. Group comparisons were carried out using Wilcoxon two-sample and Kruskal-Wallis tests. For discrete data, chi-square analysis was used and Fisher's exact test when the sample size was small. Stepwise logistic regression was also employed. The success rate was 64 per cent in Giessen and 66 per cent in Berne. The only factor that significantly (P < 0.001) influenced treatment success was the level of co-operation. In approximately 27 per cent of the patients at both centres, the post-treatment occlusion was an 'ideal' Class I. In an additional 38 per cent of the patients, marked improvements in occlusal relationships were found. In subjects with Class II division 1 malocclusions, in which orthodontic treatment is performed by means of activators, a marked improvement of the Class II dental arch relationships can be expected in approximately 65 per cent of subjects. Activator treatment is more efficient in the late than in the early mixed dentition. 相似文献
