The online attention analysis on orthognathic surgery research.

OBJECTIVES: Altmetrics is one of the fields of bibliometrics that seeks to assess the impact and interest of a given subject through Internet users. The aim of this study is to make an altmetric analysis of the orthognathic surgery literature. METHODS: A literature search was conducted using Dimensions app up to December 2023. A list of the 100 most mentioned articles on the topic was compiled. A Google Trends search was performed with same strategy to visualize important data regarding internet search. Charts and tables were created using Microsoft Excel and VOSviewer software to allow bibliometric visualization. RESULTS: There was a very poor correlation between the number of mentions and the number of citations (r = 0.0202). Most articles discussed on technical innovations associated to orthognathic surgery, majority related to virtual planning (n = 26). Other topics considered interesting to internet readers were complications (n = 18), surgical technique (n = 14), and psychological aspects/quality of life (n = 13). CONCLUSION: Online interest in orthognathic surgery closely aligns with the level of academic interest but is also influenced by factors such as location and economic status. The internet is a powerful tool for disseminating scientific research to a broad audience, making it more accessible and engaging than traditional academic channels.

Pioneers in Modern Craniofacial Surgery: Assessing the Academic Impact of Drs. Joseph Gruss and Paul Manson.

BACKGROUND: The authors conducted this study to assess the impact that Drs. Joseph Gruss and Paul Manson have had on craniofacial surgery through their individual contributions and through their trainees. METHODS: This was a retrospective analysis of fellows trained by either Dr. Gruss or Dr. Manson. Demographic and bibliometric measures were recorded for each fellow. Demographic factors included years since completion of fellowship training, current practice of craniomaxillofacial surgery, academic practice, and academic leadership roles. Bibliometric measures included number of publications, number of citations, and h-index. To adjust for scholarly activity before fellowship training, only contributions published after fellowship training were included. RESULTS: Over a 39-year period, a total of 86 surgeons completed fellowship training with either of the two principal surgeons. The mean time since completion of training was 18.7 ± 11.4 years. Seventy-nine percent of surgeons had active practices in craniomaxillofacial surgery; 54 percent had academic practices. The mean number of publications was 26.4 ± 69.3, the mean number of citations was 582 ± 2406, and the average h-index was 6.7 ± 10.6. Among academic surgeons, the average h-index was 10.7 ± 13.1, 89 percent practiced in North America, 89 percent had active practices in craniomaxillofacial surgery, and nearly 50 percent had achieved a leadership role. CONCLUSIONS: Modern craniofacial reconstruction has evolved from principles used in trauma and correction of congenital differences. The extensive impact that Drs. Paul Manson and Joseph Gruss have had on the field, and plastic surgery at large, is evident through their primary contributions and the immense impact their trainees have had on the field.

An assessment of the compliance of systematic review articles published in craniofacial surgery with the PRISMA statement guidelines: A systematic review.

CONTEXT: Systematic review evidence is increasing within craniofacial surgery. Compliance with recognised reporting guidelines for systematic review evidence has not been assessed. OBJECTIVE: To assess the compliance of systematic reviews published in craniofacial journals with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting criteria. DATA SOURCES, SEARCH TERMS AND STUDY SELECTION: Thomson Reuters impact factor was used to identify three top craniofacial journals. A search for all systematic review articles published in these journals from 1st May 2010 to 30th April 2015 was conducted using MEDLINE PubMed. DATA EXTRACTION: Two independent researchers assessed each study for inclusion and performed the data extraction. Data included the article reference information; the pathology and interventions examined and compliance of each review article with the PRISMA checklist. DATA SYNTHESIS AND RESULTS: 97 studies were returned by the search. 62 studies proceeded to data extraction. The mean percentage of applicable PRISMA items that were met across all studies was 72.5% (range 28.6-96.2%). The area of poorest compliance was with the declaration of a study protocol (19.4% of studies). Only 37.1% of studies declared their source of funding. CONCLUSIONS: Compliance of systematic review articles within craniofacial surgery with areas of the PRISMA checklist could be improved.

Condylar resorption after orthognathic surgery: A systematic review.

INTRODUCTION: Condylar resorption after orthognathic surgery (CROS) represents a progressive alteration of shape and volume of the mandibular condyle. It is a known factor of surgical relapse. The aim of this systematic review was to discuss the physiopathology, mechanisms, risk factors, diagnosis and treatment of this disease. MATERIALS AND METHODS: A systematic review of the literature was performed on the Pubmed database from 1970 to 2014, using following terms: ("orthognathic surgery") AND ("condylar resorption" OR "progressive condylar resorption" OR "idiopathic condylar resorption" OR "condylar atrophy" OR "condylolysis"). Papers were included according inclusion and exclusion criterias. RESULTS: The search leaded to 32 articles. Seventeen were included. CROS was a condylar remodeling secondary to an imbalance between mechanical stress applied to the temporomandibular joints (TMJ) and the host adaptive capacities. It mainly occurred in 14 to 50years old women with pre-existing TMJ dysfunction, estrogen deficiency, class II malocclusion with a high mandibular plane angle, a diminished posterior facial height and a posteriorly inclined condylar neck. Mandibular advancement superior to 10mm, counterclockwise rotation of the mandible and posteriorly condylar repositioning were associated with an increased risk of CROS. DISCUSSION: Treatment consists in re-operation in case of degradation of the occlusal result after an inactivity period of at least 6 months. Condylectomy with allogenic or autologous reconstruction is an alternative. Prevention is crucial and requires at-risk patient information.

[Implant-borne prosthetic rehabilitation in patients with cleft lip and palate: A retrospective study on 43 patients]. / Réhabilitation implanto-portée des patients porteurs de fentes labio-alvéolo-palatines : étude rétrospective sur 43 patients.

INTRODUCTION: Implant-borne rehabilitation in cleft lip and palate patient are aimed to allow for good orofacial functions, stable occlusion, and adequate support for the naso-labial region. The goal of our study was to evaluate the functional and esthetic results of the implant-born dental rehabilitation of the cleft lip and palate patients in our department. MATERIAL AND METHODS: Our retrospective study concerned patients operated between 1995 and 2010 in our department. All included patients suffered from a cleft alveolus and lip, with or without cleft palate. Dental implants were placed in the bone-grafted alveolus and the end of growth and at distance from the bone graft procedure. Criteria of implant survival and implant-borne rehabilitation success were defined. RESULTS: A total of 78 implants were placed in 43 patients between 1995 and 2010. Two implants were lost (implant survival rate: 97.4%). Despite this loss, all the patients could be rehabilitated with good functional and esthetic results. DISCUSSION: Implant-borne rehabilitation is a reliable solution for prosthetic rehabilitation in patients with cleft lip and palate. This solution allows for avoiding removable prosthesis and dental mutilation.

Survey of Australasian oral and maxillofacial surgeons 2011--scope and workforce issues.

This study examined the qualifications, training, and practice patterns of oral and maxillofacial surgeons in Australia in 2011. This information was compared to similar studies performed in 1986 and 1995. It was found that dentoalveolar surgery comprised the greatest proportion of practice. There had been major growth in dental implantology, orthognathic surgery, and management of pathology. These increases were directly related to the standardization and increase in qualifications and training. The workforce had increased at the highest rate predicted, but was only just keeping up with the increases in population and the number of general health practitioners.

Evaluation of the scope and practice of oral and maxillofacial surgery in Nigeria.

BACKGROUND: Oral and maxillofacial surgery is still evolving, with the scope of practice in Nigeria inadequately determined. AIMS AND OBJECTIVES: This study aims to ascertain the level of practice in various parts of the country vis-a-vis the global trend and factors influencing the scope in Nigeria. DESIGN OF THE STUDY: Cross-sectional. SETTING: The study was carried out at the University of Ibadan. Participants included all the maxillofacial surgeons on the mailing list of the Nigerian Association of Oral and Maxillofacial Surgeons and Practicing in Nigeria as at December, 2012. MATERIALS AND METHODS: Structured questionnaires were delivered to all on the mailing list of the Nigerian Association of Oral and Maxillofacial Surgeons. Respondents were asked to provide information about their demographics, years of practice, areas of practice and factors influencing the choice of practice among others. Nonresponders were reminded a month after initial contact. Data were entered into a personal computer and variables analyzed using descriptive statistical analysis. RESULTS: Thirty-two (56%) of the 57 questionnaires were returned. Most respondents were aged 41-45 years ( n = 11, 34.4%). Twenty-six (81.3%) were males, whereas 6 (18.8%) were females. Twenty respondents (62.5%) practiced in the teaching hospitals. Eighteen respondents (56.3%) practiced in the south-west geopolitical region. Twelve respondents (37.5%) were the only maxillofacial surgeons in their centers. 81.3% routinely practiced traumatology against 15.6% for implantology. Seventy-eight percent ( n = 25) had satisfactory facilities for traumatology, dentoalveolar surgery, and cleft repair surgery, while facilities were least satisfactory in implantology and orthognathic surgery (15.6% and 12.5%, respectively). The highest single factor influencing choice/area of practice was financial reward (100% of respondents). Fifty percent ( n = 16) claimed not to have had adequate training in their area of interest. Most respondents (93.8%) believe the greatest challenge facing oncological maxillofacial surgery in Nigeria was late presentation of patients. CONCLUSION: The scope of practice of oral and maxillofacial surgery is largely limited in the country relative to what obtains globally.

[Psychological effects of orthognatic surgery and postoperative dissatisfaction: presentation of a research protocol]. / Effets psychologiques de la chirurgie orthognatique et insatisfaction postopératoire : présentation d'un protocole de recherche.

INTRODUCTION: The causes of postoperative dissatisfaction in orthognathic surgery are difficult to grasp. The aims of our study are to analyze the effects of orthognathic surgery on self-esteem, body image, psychological morbidity, and quality of life. We also want to assess the combined effects of these factors on postoperative dissatisfaction, and to study the interest of personality assessment (especially neuroticism) as a predictive factor of dissatisfaction. METHOD: Three hundred patients candidates for maxillo-mandibular osteotomy will be included in the study. They will answer a questionnaire assessing self-esteem, body image, psychological morbidity, quality of life, and personality. The evaluation will be conducted preoperatively and postoperatively at 3 months and at 1 year. The degree of satisfaction will be measured postoperatively. EXPECTED RESULTS: The results should help evaluate the psychological effects of orthognathic surgery and identify predictors of postoperative dissatisfaction, and especially the role of neuroticism.

Reconstruction of oral mucosal defects using the nasolabial flap: clinical experience with 22 patients.

BACKGROUND: Various surgical options are available for reconstruction of intraoral soft tissue defects. For smaller defects of the oral mucosa in different anatomic locations of the oral cavity the nasolabial flap is a very useful and simple alternative to other pedicled flaps and free flaps. METHODS: The results of reconstruction of oral mucosal defects or facial skin defects using 29 nasolabial flaps in 22 patients were reviewed retrospectively. RESULTS: The patient group consisted of 16 patients (70%) with squamous cell carcinoma of the oral cavity, 2 patients (10%) with cystic lesions of the maxilla, 3 patients (15%) with osteonecrosis of the jaw, and 1 patient with an oral metastasis of a lung carcinoma. Healing was uneventful in 93%, partial or complete flap loss was observed in 7%. CONCLUSIONS: The nasolabial flap is a valuable alternative for reconstruction of smaller defects of the oral cavity in particular in older and medically compromised patients.

Reconstruction of mandibular defects - clinical retrospective research over a 10-year period -.

BACKGROUND: Functional and cosmetic defects in the maxillofacial region are caused by various ailments and these defects are addressed according to their need. Simplicity of procedure, intact facial function and esthetic outcome with the least possible donor site morbidity are the minimum requirements of a good reconstruction. Oro-mandibular reconstruction, although a challenge for the head and neck reconstructive surgeon, is now reliable and highly successful with excellent long-term functional and aesthetic outcomes with the use of autogenous bone grafts. Reconstruction of trauma- or mandibular oncologic defects with bony free flaps is considered the gold standard. However the the optimal reconstruction of mandibular defects is still controversial in regards to reconstructive options which include the donor site selection and the timing of surgery. The purpose of this study was to determine the outcome of different osseous reconstruction options using autogenous bone grafts for mandibular reconstructions. METHODS: This study was carried out on 178 patients with mandibular bone defects. They were reconstructed with autogenous bone grafts from different donor sites. At post operative visits they were evaluated for functional and cosmetic results. RESULTS: The success rate found in this study was around 90%. Only 7.6% of the cases showed poor results regarding facial contours and mouth opening. All other patients were satisfied with their cosmesis and mouth opening at the recipient sites was in the normal range during last follow-up visits. Donor sites were primarily closed in all cases and there was no hypertrophic scar. CONCLUSION: Based on this study, autogenous bone grafts are a reliable treatment modality for the reconstruction of mandibular bone defects with predictable aesthetic and functional outcomes. As the free vascularized fibular flap has the least resorption and failure rate, it should be the first choice for most cases of mandiblular reconstruction.

Regression models for patient-reported measures having ordered categories recorded on multiple occasions.

OBJECTIVES: The article reviews proportional and partial proportional odds regression for ordered categorical outcomes, such as patient-reported measures, that are frequently used in clinical research in dentistry. METHODS: The proportional odds regression model for ordinal data is a generalization of ordinary logistic regression for dichotomous responses. When the proportional odds assumption holds for some but not all of the covariates, the lesser known partial proportional odds model is shown to provide a useful extension. RESULTS: The ordinal data models are illustrated for the analysis of repeated ordinal outcomes to determine whether the burden associated with sensory alteration following a bilateral sagittal split osteotomy procedure differed for those patients who were given opening exercises only following surgery and those who received sensory retraining exercises in conjunction with standard opening exercises. CONCLUSIONS: Proportional and partial proportional odds models are broadly applicable to the analysis of cross-sectional and longitudinal ordinal data in dental research.

IRMER regulations: compliance rate of radiograph reporting by non-radiology clinicians.

AIM: To assess compliance with regulation 7(8) of Ionizing Radiation Medical Exposure Regulations (IRMER) 2000 legislation amongst non-radiologists reporting radiographs in a large district general hospital. MATERIALS AND METHODS: A prospective review of 100 consecutive radiography request cards from five different departments undertaking their specialty radiograph reporting were collected over 4 weeks. The requests were then traced to their respective case notes to assess documentation of radiographs. The five departments included chest, maxillo-facial, rheumatology, orthopaedics, and inpatients. Twenty-two case notes were gathered from chest clinics, 21 from maxillo-facial, 15 from rheumatology, 23 from orthopaedics fracture clinics, and 19 were taken from inpatients. RESULTS: Only 53% of radiographs undertaken by non-radiologists had a documented report. The specialty most compliant with IRMER was orthopaedics 17/23 (74%) and the specialty least compliant was maxilla-facial 8/21 (38%). Of the documented radiographs, the consultant grade was the largest group of doctors [36% (19/53)] that undertook documentation, and for the undocumented radiographs, they were also the largest group of clinicians that did not document radiographs [77% (36/47)]. All radiographs that were documented in the notes also had documented interpretation of the radiograph. CONCLUSION: Only 53% of plain radiographs were documented and reported by non-radiology clinicians even though IRMER legislation applies to all clinicians undertaking radiograph interpretation. All clinicians undertaking interpretation of radiographs should be made aware of this legislation and the responsibility to document their findings.

Facial soft tissue response to anterior segmental osteotomies: a systematic review.

Bimaxillary protrusion is prevalent among Asians and anterior segmental osteotomies are commonly used for its surgical correction. The objective of this study was to evaluate the soft tissue changes resulting from anterior segmental osteotomies. The electronic databases PubMed, Scopus and ISI Web of knowledge were searched for potentially eligible studies using a set of predetermined keywords. Full texts meeting the inclusion criteria were retrieved and their references were manually searched for additional relevant articles. The study details and outcome data of these reports were extracted using spreadsheets for comparison. The methodological quality of each study was assessed. Eleven studies met the inclusion criteria. Lateral cephalometry was used in all studies. A reduction of the labial prominence with an increase in the nasolabial angle was noted subsequent to anterior segmental osteotomies. The magnitude of the reported soft tissue changes and their ratios corresponding to the osseous movements varied among studies. Long-term, prospective, methodologically sound clinical trials with larger samples and three-dimensional quantification are required to provide sufficient information for predicting the soft tissue response to anterior segmental osteotomies.
