RESUMO
PURPOSE: Residency programs in oral maxillofacial surgery (OMS) have the lowest percentage (2020: 18.4%) of female graduates among all dental specialty programs. When considering this underrepresentation of female OMS residents, prior studies have not examined how OMS role models might shape dental students' interest in OMS careers. The objectives were to assess female versus male students' OMS-related career motivation, their experiences/attitudes toward three groups of OMS role models (i.e., OMS residents, faculty, and practitioners), and relationships between role model-related experiences/attitudes and career motivation. METHODS: 363 female and 335 male students from 14 United States and two Canadian dental schools participated in this cross-sectional study by responding to an online survey. RESULTS: 13.8% of female and 26% of male respondents (p < 0.001) were much/very much interested in OMS careers. More male than female students had shadowed an OMS in an office setting (43.4% vs. 35.1%; p < 0.05). The groups did not differ in their motivation to learn more and earlier about OMS nor in the quantity of OMS-related experiences prior to and during dental school. However, male students were more satisfied with the quality of these experiences (5-point scale with 5 = most positive: Means: 3.76 vs. 3.53; p < 0.05), were more comfortable approaching/working with OMS instructors (3.51 vs. 3.19; p < 0.01) and reported to have learned more from residents (3.52 vs. 3.31; p < 0.05) and faculty (3.75 vs. 3.45; p < 0.01) than female students. Female students agreed less that OMS residents, faculty, and practitioners encouraged students to pursue OMS (3.27 vs. 3.44; p < 0.01 / 3.46 vs. 3.63; p < 0.01 / 3.45 vs. 3.61; p < 0.01). Role model-related experiences and attitudes correlated with an interest in an OMS career. CONCLUSIONS: The two groups do not differ in the quantity of most OMS experiences before and during dental school and their motivation to learn more and earlier about OMS. However, female students' less positive OMS-related educational experiences and less positive attitudes toward role models correlate with a lower interest in OMS careers.

PURPOSE: Optimal correction of the cleft nasal deformity remains challenging. The purpose of this study was to examine the practice patterns and postoperative course of patients undergoing cleft lip repair with rhinoplasty compared to those who have primary lip repair without rhinoplasty. METHODS AND MATERIALS: A retrospective cohort study was conducted based on the Kids' Inpatient Database. Data were collected from January 2000 to December 2011 and included infants aged 12 months and younger who underwent cleft lip repair. The predictor variable was the addition of rhinoplasty at primary cleft lip repair. Primary outcome variables included hospital setting, year, and admission cost, while secondary outcome variables included length of stay and postoperative complication rate. Independent t-tests and chi-squared tests were performed. Continuous variables were analyzed by multiple linear regression models. RESULTS: The study sample included 4559 infants with 1422 (31.2%) who underwent primary cleft rhinoplasty. Over time, there was a significant increase in the proportion of cleft lip repairs accompanied by a rhinoplasty (p < .01). A greater proportion of patients with unilateral cleft lips received simultaneous rhinoplasty with their lip repairs (33.8 vs 26.0%, p < .01). This cohort had a significantly shorter length of stay (1.6 vs 2.8 days, p < .01) when compared to children that underwent cleft lip repair alone. CONCLUSIONS: Performing primary cleft rhinoplasty is becoming more common among cleft surgeons. Considering comparable costs and complication rates, a rhinoplasty should be considered during the surgical treatment planning of patients with cleft nasal deformities.

INTRODUCTION: Children with cleft are at high risk for sleep-disordered breathing (SDB). However, little is known about the impact of SDB in this pediatric population. The aim of this study was to investigate whether SDB play a role in behavior and quality of life (QoL) in young children with cleft. METHODS: Cross-sectional study of 95 children aged 2.0-7.9 years with cleft palate. Parents completed a sleep (Pediatric Sleep questionnaire), a behavior (Conners' Early Childhood scale), and a generic health-related QoL (KINDL questionnaire) assessment. Symptomatic children were referred for a polysomnography (PSG). RESULTS: Overall, 14.7% of children (49.5% boys) screened positive for SDB and 27.4% had a PSG, which identified 84.6% with sleep apnea (apnea-hypopnea index [AHI] ≥1) and 27.2% with AHI ≥5. Positive screening for SDB was associated with elevated T-scores for anxiety and physical symptoms, significant differences in mean T-scores for inattention/hyperactivity (64.2 ± 15.7 vs. 53.9 ± 11.4, p = .02), social functioning/atypical behaviour, social functioning (60.6 ± 11.7 vs. 51.9 ± 7.3, p = .004 and 59.5 ± 10.9 vs. 51.2 ± 8.0, p = .01) and mood (57.5 ± 8.2 vs. 50.7 ± 8.2, p = .03). Lower QoL scores for emotional and family well-being were also reported in children with SDB (80.7 ± 13.4 vs. 90.0 ± 8.7, p = .01, 66.7 ± 15.8 vs. 76.9 ± 11.9, p = .04). Children with AHI ≥5 compared to those with AHI ≥1 and <5 showed significant differences in mean T-score for aggressive behaviour (65.2 ± 12.1 vs. 52.3 ± 11.3, p = .04), defiant temper (62.8 ± 9.2 vs. 51.6 ± 10.2, p = .03) and lower family QoL scores (59.4 ± 15.2 vs. 77.1 ± 9.6, p = .006). CONCLUSIONS: In children with cleft palate the presence of SDB symptoms and moderate/severe sleep apnea was associated with behavioral (internalizing/externalizing) problems and lower family well-being.

PURPOSE: The purpose of this study was to describe 3 cases of tongue cancer in patients less than 21 years of age. Secondarily, a literature review was performed to examine disease presentation, risk factors, prognosis, and treatment strategies for young persons with tongue cancer. METHODS: The authors presented 3 cases of childhood tongue cancer between 2009 and 2020 at the University of Michigan Department of Oral and Maxillofacial Surgery (Ann Arbor, MI). An electronic literature review was conducted via PubMed, Embase, Web of Science, and MLibrary. RESULTS: Including the present case series, 64 studies reporting 108 cases were identified. Age at presentation ranged from newborn to 20 years, with a mean age of 14.5 years. The majority of patients were female (52.2%); 68.1% of patients presented with T1 or T2 disease. Nodal metastases were seen in 56.1% of patients. The most commonly identified predisposing factors included Fanconi anemia (13.9%), bone marrow transplant (9.3%), tobacco use (6.5%), and xeroderma pigmentosum (4.6%). Most patients received surgery alone (37.5%), followed by surgery with adjuvant radiation (33.8%); 60.6% underwent neck dissection. Overall survival was 60.3% at 1 year and 43.6% at 5 years. CONCLUSIONS: Oral tongue cancer in the young is a rare disease with poorly understood etiology. There is a need for oncologists and maxillofacial surgeons to collaborate in the study of genetic, social, environmental, and medical risk factors contributing to the disease. All patients should undergo high-throughput genetic sequencing to expand our understanding of the disease process and allow for targeted treatment strategies.

PURPOSE: While the numbers of oral maxillofacial surgery (OMFS) residents increased over time, women and residents from underrepresented minority backgrounds are still underrepresented. The objectives were to assess dental students' OMFS-related personal and educational experiences and attitudes and explore which factors correlate with their interest in future OMFS careers. METHODS: Data were collected from 493 dental students in 1 dental school and 206 students from 15 other US and Canadian dental schools. RESULTS: The students in the national sample were more likely to have experienced an OMFS procedure themselves (64.6% vs. 50.7%; P = 0.001), have shadowed an OMFS in an operating room (23.2% vs. 14.9%; P = 0.009) prior to coming to dental school and to be much/very much interested in an OMFS career (36.4% vs. 12%; P < 0.001) than the students at the home school. While the majority of both groups rated their experiences with rotations in the OMFS department in the dental school (68% vs. 62.5%) and in the hospital (80.3% vs. 85.7%) as very interesting, the students in the national sample were more likely to agree/strongly agree that they were satisfied with their OMFS experiences (68.1% vs. 36.3%; P < 0.001) and had learned a lot from the OMFS faculty (57.9% vs. 30.8%) than the students in the home school. For both groups, the degree of interest in an OMFS career correlated with having had more personal OMFS experiences (home: r = 0.28; P < 0.001/other: r = 0.39; P < 0.001), more interesting OMFS experiences in the dental school (r = 0.23; P < 0.05/r = 0.40; P < 0.001) and the hospital (0.33; P < 0.05/r = 0.50; P < 0.001) and more positive attitudes toward OMFS faculty (r = 0.26; P < 0.001/r = 0.37; P < 0.001). CONCLUSIONS: Positive personal and educational OMFS experiences and positive attitudes toward OMFS faculty were associated with an interest in OMFS careers. These findings provide a basis for developing educational interventions aimed at increasing the percentage of women and residents from URM backgrounds in OMFS programs.

Fabricating an immediate complete denture can be very challenging in some clinical situations. This clinical report describes a digital workflow to fabricate a printed maxillary immediate complete denture for a patient with a severely compromised maxilla. Digital data obtained by using an intraoral scanner was utilized to reconstruct the three-dimensional (3D) image of the jaws at the desirable vertical dimension of occlusion. After performing the virtual teeth extraction and alveoloplasty, the denture base and teeth were designed. The resulting data were exported to a 3D printer for denture fabrication and the 3D printed (additively manufactured) denture was successfully inserted immediately after the surgery. After initial healing and confirmation of good retention and function, a new printed denture was fabricated by digitally duplicating the relined denture maintaining the same teeth positions but adjusting the base to a new intraoral scan of the healed ridge.

Preparation and planning for orthognathic surgery in late adolescence depends on the complexity of unresolved problems with which the patient presents. Different strategies are presented to address these unresolved problems in the adult patient with cleft lip and palate. Different surgical and orthodontic treatments are presented to correct the class III malocclusion in patients with cleft lip and palate in ranges that are analogous to the envelope of discrepancy. For complex cases, the principles of achievability, stability, and esthetics should guide the decision-making process for planning the preparation for orthognathic surgery.

OBJECTIVES: The aim of this study was to compare three-dimensional airway changes resulting from mandibular advancement surgery and mandibular advancement surgery with constriction. SETTING AND SAMPLE POPULATION: The University of Michigan School of Dentistry and Medical Center. A total of 42 patients undergoing mandibular advancement with or without simultaneous constriction. MATERIALS AND METHODS: A retrospective airway evaluation of patients undergoing mandibular advancement with or without simultaneous mandibular constriction was performed. Cross-sectional evaluation at standardized locations, minimum cross section and volumetric analysis were performed using Dolphin Imaging TM Version 11.7. RESULTS: Patients undergoing mandibular advancement with or without constriction experienced significant airway increases (P < 0.05). Patients who underwent mandibular advancement only gained nearly twice as much airway volume as mandibular advancement with simultaneous constriction (8.69 mm3 vs 4.3 mm3 ). The largest increase for both groups was observed in the minimum axial area in the oropharynx segment (119.5 mm2 ) and the axial area of the retroglossal region (137.2 mm2 ). CONCLUSIONS: The findings demonstrate mandibular advancement with constriction results in airway enlargement following surgery.

Class III open bite malocclusion can be among the most difficult case types to obtain an excellent occlusal, skeletal, and facial outcome. Treatment options include growth modification, extraction for orthodontic camouflage, and orthognathic surgery. For the most severely affected and non-growing patients, orthognathic surgery is often the most predictable and, in some situations, the only viable way of achieving an optimal result. The risks and benefits of surgical treatment options can occasionally be difficult to assess particularly for providers with limited experience. Two-dimensional surgical predictions can assist but do not permit the third dimension to be visualized. New techniques of computer-aided surgical simulation can enable the surgeon, orthodontist, and patient to better visualize and understand the treatment approach and enable them to make the most effective and efficient treatment related decisions. This case merges knowledge of the full spectrum of historical surgical techniques with the new approach of computer-aided surgical simulation (CASS) to perform complex segmental maxillary and mandibular surgery to obtain an excellent functional and esthetic result.

BACKGROUND AND OVERVIEW: A 9-year-old girl underwent comprehensive resection and rehabilitation of a central giant cell granuloma that required phased interprofessional collaborative care to optimize treatment decisions and outcome. CASE DESCRIPTION: The interprofessional treatment team included an oral and maxillofacial surgeon, maxillofacial prosthodontist, dentist, orthodontist, and speech-language pathologist, and treatment spanned 9 years. Treatment included surgical resection of a central giant cell granuloma and obturation with a removable interim prosthesis. After adequate growth and development, the patient then underwent a surgical free-tissue transfer reconstruction by using virtual surgical planning, followed by dental implant placement and a transitional restoration, subsequent orthodontic therapy, and eventual definitive rehabilitation with an implant-retained fixed hybrid prosthesis. CONCLUSIONS AND PRACTICAL IMPLICATIONS: The interprofessional phased and collaborative treatment facilitated an optimal functional and esthetic process in a young patient with transitional and definitive treatments that considered long-term quality-of-life implications.

Microvascular reconstruction of ablative defects has become a mainstay of contemporary management of head and neck cancer patients. These techniques offer myriad tissue options that vary in character, volume, and components and have vastly improved the esthetic and functional outcomes achieved in this patient population. Although consensus exists regarding the reliability and functional and esthetic benefits of free tissue transfer, the same cannot be said for oncologic outcomes. The increase in resources required for the routine use of free tissue transfer has led to asking this question-Do vascularized free flaps allow for increased surgical margins and improvements in oncologic outcomes?

BACKGROUND: Stem cell therapy with bone marrow-derived mesenchymal stem cells is a promising tissue engineering strategy to promote regeneration of craniofacial bone. PURPOSE: To determine whether cell therapy with ex vivo expanded stem cell populations would be safe and efficacious in the regeneration of large alveolar defects in patients with a history of cleft palate or craniofacial trauma. MATERIALS AND METHODS: Eighteen patients (10 patients with traumatic injury and 8 patients with cleft palate) presenting with missing teeth associated with horizontal alveolar bone deficiencies were included in this randomized controlled clinical trial. Patients were randomized to receive either conventional autogenous block grafts or stem cell therapy. After a healing period of 4 months the treated sites were re-entered and the bone width re-assessed prior to implant placement. Implant stability was evaluated through torque testing of the implant upon insertion and at 6 months postloading. RESULTS: The mean gain in bone width was 1.5 ± 1.5 mm in the stem cell therapy group and 3.3 ± 1.4 mm in the control group. Overall, bone gain was higher in trauma patients as compared to patients with cleft palate, for both the control and the stem cell therapy groups. Most postoperative complications were wound dehiscences and incision line openings. Implants were placed successfully in 5 out of 10 patients in the stem cell therapy group and in all 8 patients in the control group. One implant from the control/cleft palate group failed before loading, while the rest of the implants were loaded successfully and remained stable at 6 months. The patients who did not receive implants were re-treated with autogenous block bone graft. CONCLUSION: The ability of stem cells to treat large alveolar defects is safe, yet, their ability to completely reconstitute large alveolar defects is limited. This approach requires further optimization to meet the outcomes seen using current methods to treat large defects, particularly those resultant of cleft palate.

We investigated the change in the natural head position and its relation to the change in the mandibular position in patients with mandibular hypoplasia. Forty-one patients treated by orthognathic surgery were divided into three groups: bilateral sagittal split osteotomy (BSSO) advancement (n=8); BSSO advancement with genioplasty (n=12), and Le Fort I osteotomy with BSSO advancement (n=21). Cone-beam computed tomographic (CT) datasets were collected preoperatively and six weeks postoperatively. The natural head position was measured using the craniocervical angle and the distance from the second vertebra to the frontal plane, and the mandibular position was measured using the craniomandibular angle and the distance from the mandible to the frontal plane. Repeated measures two way ANOVA was used to assess the significance of differences between the angular and linear measurements, and Pearson's correlation coefficient to assess those between the change in the mandibular position and the natural head position. The craniomandibular angle increased and the mandible to frontal plane distance decreased, as planned; the craniocervical angle increased, and the distance from the second vertebra to the frontal plane decreased in all three groups. ANOVA showed a significant difference in the time factor (preoperative compared with postoperative) but no significant differences between the groups or interaction (time multiplied by group) factors. There was a significant correlation between the change in mandibular position and the change in the natural head position. Changes in the natural head position after correction of mandibular hypoplasia are correlated with the change in the mandibular position, regardless of whether a genioplasty or Le Fort I osteotomy was done.

The aims of this study were to determine whether male vs. female oral and maxillofacial surgery (OMS) residents, academic surgeons (i.e., faculty members), and private practitioners in the U.S. differed in their general career satisfaction and job/professional satisfaction. Survey data were collected in 2011-12 from 267 OMS residents (response rate 55%), 271 OMS academic surgeons (response rate 31%), and 417 OMS private practitioners (response rates 13% web-based survey and 29% postal mail survey). The results showed that while the male vs. female OMS private practitioners and academic surgeons did not differ in their career satisfaction, the female residents had a lower career satisfaction than the male residents (on four-point scale with 4=most satisfied: 3.03 vs. 3.65; p<0.01). The male vs. female OMS private practitioners and academic surgeons also did not differ in their job satisfaction. However, the female residents agreed on average less that they were able to practice OMS in the way they want, felt less proud to be an oral and maxillofacial surgeon, were less satisfied with their career, and were more likely to consider a career change in the next five years than the male residents. While these male and female oral and maxillofacial surgeons in private practice and academia did not differ in their career and job satisfaction, the male and female residents differed significantly, with female residents reporting a significantly poorer career and job satisfaction than male residents. Future research needs to explore ways to improve career and professional satisfaction of female OMS residents.

Epidemiologic data have shown changes in the demographic profile of patients presenting with oral cavity squamous cell carcinoma (SCC) during the past 4 decades. In particular, there has been a marked increase in the number of young women without a history of smoking presenting with SCC of the tongue. A Surveillance, Epidemiology, and End Results review of patients with head and neck cancer identified 5.3% younger than 40 years. After comparing cohorts from 1973 to 1984 with 1985 to 1997, a 60% increase in tongue cancer in patients younger 40 years was noted. Epidemiologic data also have shown that women are tending to delay childbearing to an older age. These 2 factors have resulted in an increasing prevalence of cancer diagnosed during pregnancy. If current trends continue, oral surgeons and maternal fetal medicine obstetric specialists will see an increasing number of pregnant patients presenting with malignancies. This in turn will lead to a number of complex surgical and adjuvant treatment considerations resulting in ethical and moral decisions for which limited data exist to guide best practice. The treatment chosen will affect not only the health of the patient, but also the health of the fetus and ongoing pregnancy. This report describes the case of a woman who was diagnosed with SCC of the tongue at 14 weeks' gestational age. This report presents her treatment course and a review of the literature to support her decisions related to the care given.

BACKGROUND: Limited outcome data exist regarding the survival of microvascular free flaps for head and neck reconstruction in children. The objectives of this study were to perform a systematic review of the literature and meta-analysis comparing the survival of the most commonly used free flaps used for head and neck reconstruction in children. METHODS: A systematic search of PubMed, Embase, and Scopus was conducted using various keywords up to January 1, 2015. Meta-analysis was used to compare the survival of the most commonly used free flaps. The primary predictor variable was free flap type. The primary outcome variable was flap failure. The pooled relative risk (RR) with 95% confidence intervals (CIs) was estimated using a Mantel-Haenszel, fixed-effects model. RESULTS: The authors reviewed 25,303 abstracts. Five studies met inclusion criteria. A total of 646 children received a total of 694 free flaps. The pooled survival rate among all free flaps was 96.4%. The fibula free flap (fibula) and subscapular system free flaps (scapula) were the most commonly used flaps. There was no difference in survival when comparing the scapula (RRâ=â0.59, 95% CI: 0.26, 1.56, Pâ=â0.29), or fibula (RRâ=â1.91, 95% CI: 0.55, 6.65, Pâ=â0.31) to other free flaps, or when comparing the scapula to the fibula (RRâ=â2.29; 95% CI: 0.40, 13.08, Pâ=â0.35). CONCLUSIONS: Free tissue transfer is highly successful in children. Although data are limited, there appears to be no difference in survival among various free flaps used for head and neck reconstruction in children.
