RESUMO
PURPOSE: Upper Airway Stimulation (UAS) of the hypoglossal nerve is a rapidly growing management option for patients with obstructive sleep apnea (OSA). Our study compares the treatment efficacy of UAS between those who were initially ineligible for UAS but subsequently met eligibility after multilevel surgery versus those who underwent isolated UAS for the treatment of moderate to severe OSA. METHODS: The investigators implemented a retrospective single-center cohort study of patients aged 18+ years who presented for surgical evaluation of OSA from 2016-2019 and underwent UAS implantation. The predictor variable was eligibility status for UAS. Initially ineligible subjects were defined as having an apnea-hypopnea (AHI) > 65 events/hr, body mass index (BMI) > 32 kg/m2, or complete concentric collapse (CCC) on drug-induced sleep endoscopy. Eligible subjects were defined as having an AHI between 15 and 65, with no CCC on drug-induced sleep endoscopy. The primary outcome was change in AHI which was measured preoperatively and 6 months post UAS implantation. Secondary outcomes were change in Epworth sleepiness scale and Fatigue severity scale. Covariates were age, sex, and BMI. Data analysis involved descriptive statistics and multivariable statistical models; P < .05 was considered significant. RESULTS: Thirty six patients underwent UAS implantation from 2016-2019. Eighteen patients who were initially ineligible for UAS underwent multilevel surgery, including uvulopalatopharyngoplasty, distraction osteogenesis maxillary expansion, or maxillomandibular advancement. Mean age was 62.4 ± 9 years and BMI of 29.1 ± 4 kg/m2 with 5 female patients. The cohort of 17 patients who met criteria for UAS from the start had a mean age of 62.9 ± 14 years and mean BMI of 26.7 ± 4 kg/m2 with 2 female patients. Mean AHI reduction for the multilevel group was 37.6 ± 21.2 events per hour (P < .001). Mean AHI reduction for the UAS-only group was 31.5 ± 13 events per hour (P < .001). When adjusted for age, BMI, and sex, the multilevel group had a more significant reduction (18 AHI events) compared to the isolated group (P < .001). CONCLUSIONS: For patients who are ineligible for UAS due to severity of OSA or CCC of the velum, multilevel surgery including maxillomandibular advancement followed by UAS confers effective post-treatment results, which was superior to the UAS-only group.

ABSTRACT: Temporomandibular joint (TMJ) ankylosis in children can alter facial development and affect oral hygiene and function. Surgical release of the ankylosis is the mainstay of treatment. The authors hypothesize that preoperative arterial coil embolization is safe and effective in preventing major blood loss during TMJ surgery (loss prompting blood transfusion or hemodynamic instability requiring vasoactive medication administration) in children with TMJ ankylosis. Patients < 16 years who were diagnosed with TMJ ankylosis (<15 maximal interincisal opening) and had embolization before surgery in the last 5 years were included. Out of 9 initial search results, 3 patients were excluded (age > 16). Information gathered were patient demographics, diagnostic imaging, procedural details, complications, and clinical outcomes. Six patients, mean age 11.14 years (range 7-15 years) year and a mean weight of 40.8 ± 19 kg were included. Underlying etiologies for TMJ ankylosis: Pierre Robin Syndrome (n = 2), juvenile rheumatoid arthritis (n = 1), Goldenhar's syndrome (n = 1), trauma (n = 1), and micrognathia (n = 1). Neck computed tomography angiogram before embolization demonstrated an intimate approximation between the internal maxillary artery (IMAX) and/or external carotid artery and ankylotic mass in all patients. Eight successful embolizations were performed without procedural complication. In 1 patient with angiographic evidence of surgical internal maxillary artery ligation, embolization was performed via collaterals. Surgery was performed within 48 hours of embolization. Airway access during surgery was via nasal intubation (n = 4), oral intubation (n = 3). The estimated blood loss (EBL) during surgery was 78.33 ± 47.08 ml. Three patients had subsequent TMJ surgery with a mean estimated blood loss of 73.33 ± 46.18 ml. After a mean follow-up of 17 ± 15 months, patients showed a 13.8mm mean increment of maximal interincisal opening with 95% CI (5.74-21.9), P < 0.007.

PURPOSE: The apnea-hypopnea index (AHI) is the parameter on which the severity of obstructive sleep apnea (OSA) is based and is also the determinant for both clinicians and third-party payers for surgical procedures. The purpose of this retrospective cross-sectional chart review is to examine differences in symptoms and AHI between men and women with OSA and whether this may impact timing and selection of surgical care. METHODS: Retrospective cross-sectional study of patients aged 18 years and older who presented at a single center for surgical evaluation of OSA from January 2017 to 2020. AHI, oxygen desaturation index, respiratory disturbance index, and lowest oxygen saturation were obtained from polysomnography. The predictor variable was gender, and the outcome variable was AHI. Unadjusted and multivariate adjusted linear regression models were used to compare differences in AHI between gender, controlling for age, body mass index (BMI), Epworth sleepiness scale, and fatigue severity scale. Poisson regression analysis with robust error was used to assess the relative risks of antidepressant and anxiolytic medication use between genders. RESULTS: A total of 408 consecutive new patients seen for surgical evaluation to treat OSA (248 men and 160 women) were included. Median patient age was 40 years for men and 41 years for women. Median AHI for men was 22.1 events per hour and 13.7 for women (P < .001). When adjusted for age and BMI, men have 33.2% higher AHI than women, with age contributing to 2% and BMI contributing to 6% of the difference. When controlling for age, BMI, Epworth sleepiness scale, and fatigue severity scale, women have a 2.2 increased relative risk of taking anxiolytic or antidepressant medications. CONCLUSIONS: Women with OSA seeking surgery in a dedicated sleep practice have 33% lower AHI than men when controlling for age, BMI, and symptoms. Based on our findings, non-gender-specific AHI may handicap the surgeon from offering the full range of available procedures to women with OSA.

PURPOSE: Becoming an oral-maxillofacial surgeon is often challenging for young trainees. The purpose of this manuscript is to explore how a student-led group, which emphasizes networking, mentorship, and academic opportunities, may impact one's journey to becoming an oral-maxillofacial surgeon. PATIENTS AND METHODS: This was a cross-sectional descriptive study where a 5-question Likert-type survey was administered to students who matriculated into residency and participated in a student-led group called Passing The Scalpel (PTS). This survey evaluated the value of PTS in providing exposure, career decision-making, networking/mentorship, and camaraderie. The results were analyzed, and statistical outcomes were evaluated. RESULTS: There was an 80.5% response rate (n = 29). Question 1 regarding first exposure to oral-maxillofacial surgery had a mean score of 2.55 (standard deviation [SD] = 1.35; χ2 = 15.39; P < .05). Question 2 regarding choosing oral-maxillofacial surgery as a career had a mean score of 3.66 (SD = 1.11; χ2 = 10.84; P < .05). Question 3 regarding offering mentorship and networking had a mean score of 4.14 (SD = 0.92; χ2 = 27.81; P < .05). Question 4 regarding increasing applicant camaraderie had a mean score of 4.21 (SD = 0.77; χ2 = 36.71; P < .05). Question 5 regarding the importance of PTS within a dental curriculum had a score of 4.48 (SD = 0.68; χ2 = 41.89; P < .05). CONCLUSION: PTS is an effective student-led initiative that emphasizes early exposure, networking, and mentorship opportunities and encourages students in choosing oral-maxillofacial surgery as a specialty. PTS demonstrates that student-led initiatives can fulfill unmet needs in the dental curriculum.

BACKGROUND: Evaluation and interpretation of the literature on obstructive sleep apnea (OSA) allows for consolidation and determination of the key factors important for clinical management of the adult OSA patient. Toward this goal, an international collaborative of multidisciplinary experts in sleep apnea evaluation and treatment have produced the International Consensus statement on Obstructive Sleep Apnea (ICS:OSA). METHODS: Using previously defined methodology, focal topics in OSA were assigned as literature review (LR), evidence-based review (EBR), or evidence-based review with recommendations (EBR-R) formats. Each topic incorporated the available and relevant evidence which was summarized and graded on study quality. Each topic and section underwent iterative review and the ICS:OSA was created and reviewed by all authors for consensus. RESULTS: The ICS:OSA addresses OSA syndrome definitions, pathophysiology, epidemiology, risk factors for disease, screening methods, diagnostic testing types, multiple treatment modalities, and effects of OSA treatment on multiple OSA-associated comorbidities. Specific focus on outcomes with positive airway pressure (PAP) and surgical treatments were evaluated. CONCLUSION: This review of the literature consolidates the available knowledge and identifies the limitations of the current evidence on OSA. This effort aims to create a resource for OSA evidence-based practice and identify future research needs. Knowledge gaps and research opportunities include improving the metrics of OSA disease, determining the optimal OSA screening paradigms, developing strategies for PAP adherence and longitudinal care, enhancing selection of PAP alternatives and surgery, understanding health risk outcomes, and translating evidence into individualized approaches to therapy.

OBJECTIVE: To determine if a modified tissue-preserving palatopharyngoplasty could convert retropalatal concentric collapse to anteroposterior or lateral patterns of collapse on drug-induced sleep endoscopy (DISE) in patients who are not candidates for upper airway stimulation due to complete circumferential collapse at the velum. METHODS: A prospective, nonconsecutive, single-blinded cohort study was performed by two sleep surgeons at a tertiary care center from 2015 to 2018. Inclusion criteria included adults > 18 years of age with a diagnosis of obstructive sleep apnea with an Apnea-Hypopnea Index (AHI) > 15, a body mass index (BMI) < 32, and < 25% central apneas on polysomnography. Twelve patients with complete circumferential collapse underwent a modified palatopharyngoplasty. Postoperatively, a repeat sleep study was performed. A repeat DISE was recommended for those with incomplete surgical response (clinically and/or AHI). RESULTS: Twelve patients with complete circumferential collapse were eligible for the study. Mean BMI was 30.5. Mean preoperative AHI was 54.0 events per hour. Following a modified palatopharyngoplasty, the mean AHI was reduced to 33.1 events per hour, and 100% (12 of 12) of the patients converted from a pattern of complete circumferential collapse to either no collapse at the level of the velum (3) or an anteroposterior pattern of collapse (9). CONCLUSION: We demonstrate that a modified palatopharyngoplasty can successfully convert collapse patterns in patients with complete circumferential collapse. Further studies are required to determine the outcome of these patients following upper airway stimulation implantation. LEVEL OF EVIDENCE: 1B Laryngoscope, 2020.

PURPOSE: This study's purpose was to explore how content and format of children's oral health instruction in the dental clinic is perceived by parents and might affect parents' knowledge and behaviors. METHODS: Thirty low-income Mexican immigrant parents of children age five years and under were recruited from dental clinics in 2015 to 2016. In-person qualitative interviews in Spanish about their children's and their own experiences of dental care and home oral hygiene practices were conducted, digitally recorded, translated, and transcribed. Data analysis involved iteratively reading text data and developing and refining codes to find common themes. RESULTS: Twenty-five of 30 parents recalled receiving oral hygiene instruction, and 18 recalled receiving nutrition instruction and were included in analyses. The format and effectiveness of instruction varied. More engaging educational approaches were recalled and described in more detail than less engaging educational approaches. As a result of oral hygiene and nutritional instruction, most parents reported changing their oral hygiene home behaviors for their children; half aimed to reduce purchasing sugary foods and drinks. CONCLUSIONS: Most parents recalled receiving oral hygiene and nutrition instruction as part of their child's dental visit and reported incorporating the instruction and recommendations they received into their children's home routine.
