RESUMEN
Background: Maxillofacial trauma (MFT) caused by falls, interpersonal violence or traffic accidents leading to fractures of different facial regions, including the midface and the mandible, are common clinical conditions requiring open reduction and internal fixation. The aim of this study was to analyze the incidence and time trends in MFT-associated surgeries regarding different facial regions in the German healthcare system over time. Materials and methods: Nationwide data regarding the national diagnosis-related group (DRG) inpatient billing system was received from the German Federal Statistical Office for the years 2005-2022. We estimated the age-gender standardized incidence of MFT-associated procedures classified by the Operation and Procedure Classification System (OPS) and evaluated age- and gender-adjusted time trends using Poisson regression analysis. Results: The total standardized incidence rate of MFT-associated procedures in the observational period 2005-2022 was 25.1 (â13.3; â37.5) per 100,000 person-years within a slight significant annual decrease of 0.5%. A significant increase in the incidence of MFT-related procedures within the observational period was found in older adults from 60 to 79 years (+55.1%; â+54.8%; â+56.3%) and elderly patients over 80 years (+66.7%; â+59.1%; â+85.1%). Other significant trends are decreases in MFT-related procedures performed in children from 0-14 years (-28.1%; â-30.3%; â-27.3%) and young adults between 15 and 35 years (-20.4%; â-7.3%; â-22.5%). Conclusions: MFT-associated surgery is a persisting challenge in the German healthcare system. There is an ongoing transition in MFT-associated surgeries from younger to older patients beyond the scope of demographic change, highlighting the increasing importance of interdisciplinary treatment of patients with pre-existing conditions in maxillofacial surgery. Implementation of injury prevention measures might be beneficial in this population.
RESUMEN
Background: Arthroscopy of the temporomandibular joint (TMJ) plays a long-established role in the diagnostics and therapy of patients suffering from arthrogenic temporomandibular disorders (TMDs), which do not respond adequately to conservative/non-invasive therapy. However, the interpretation of arthroscopic findings remains challenging. This study investigates the reliability and variability of assessing arthroscopic views of pathologies in patients with TMDs by non-specialists in arthroscopy and whether a standardized assessment tool may improve correctness. Methods: Following a comprehensive one-semester lecture, dental students in the clinical stage of education were asked to rate 25 arthroscopic views (freeze images and corresponding video clips) regarding the severity of synovitis, adhesions, and degenerative changes on a scale of 0-10 (T1). The results were compared to ratings stated by two European-board-qualified academic OMF surgeons. In a second round (T2), the students were asked to repeat the ratings using a 10-point rating scheme. Results: With regard to all three subcategories, congruency with the surgeons' results at T1 was at a low level (p < 0.05 in 19/75 cases) and even decreased at T2 after the implementation of the TMDs-SevS (p < 0.05 in 38/75 cases). For both T1 and T2, therefore, the inter-rater agreement was at a low level, showing only a slight agreement for all three subcategories (Fleiss' Kappa (κ) between 0.014 and 0.099). Conclusions: The judgement of the arthroscopic pathologies of the TMJ remains an area of temporomandibular surgery that requires wide experience and training in TMDs to achieve expertise in TMJ arthroscopic assessments, which cannot be transferred by theoretical instruction alone.
RESUMEN
Background: Assessing the morphology of the superior airway space is a crucial diagnostic step in the treatment planning of patients with obstructive sleep apnea syndrome (OSAS) or prior to orthognathic surgery. The aim of this study is to evaluate the necessary scope of a two-dimensional cephalometric assessment and the necessity of three-dimensional imaging in the identification of superior airway space narrowing (SASN). Methods: The computed tomography studies of 100 non-obese, non-OSAS patients were evaluated and analyzed retrospectively. Multiplanar reconstructions were created and underwent cephalometric evaluation. The three-dimensional superior airway morphology was segmented and measured for the minimal cross-sectional area (Amin) and volume (V0). Patients were grouped according to Amin < 80 mm2 and V0 < 12 cm3. Cephalometric parameters (CPs) were analyzed according to Amin and V0 with an unpaired t-test, Pearson correlation, and ROC-curve analysis. Results: The CPs regarding sagittal airway space dimensions (IPAS, MPAS, SPAS) and mandibular body length (GoGn) show the strongest correlation to the three-dimensional minimal cross-sectional area (Amin). The ROC-curve analysis classifying for SASN led to an AUC of 0.86 for IPAS, 0.87 for MPAS, 0.88 for SPAS, and 0.63 for GoGn. Three-dimensional imaging may further improve the diagnostic accuracy in the identification of SASN for IPAS below 13.5 mm, MPAS below 10.2 mm, SPAS below 12.5 mm, and GoGn below 90.2 mm. Conclusions: Two-dimensional cephalometric sagittal airway space diameters and mandibular body length are useful initial screening parameters in the identification of superior airway space narrowing. Nevertheless, as the correlation of two-dimensional cephalometric parameters with three-dimensional upper airway space narrowing is varying and highly dependent on acquisition circumstances, indications for three-dimensional imaging, if possible, in the supine position to evaluate upper airway space morphology should be provided generously, especially in patients with low but normal airway space parameters in two-dimensional cephalometry.
RESUMEN
BACKGROUND: Temporomandibular joint (TMJ) replacement may be indicated for various pathological conditions, and the type of condition can affect the surgical procedure and outcomes. The causes of limited range of motion after alloplastic TMJ replacement have not been extensively studied. OBJECTIVES: The present study aimed to evaluate the impact of preoperative jaw anatomy and functional status on the immediate and long-term outcomes of total TMJ replacement using a two-component patient-specific TMJ endoprosthesis. MATERIAL AND METHODS: This retrospective study included 31 patients who underwent total TMJ replacement surgery between 2016 and 2020. The main outcome variable was the maximal incisal opening (MIO) after treatment. Secondary outcome variables included MIO improvement and the presence and type of postoperative complications. The primary predictive variable was the preoperative initial MIO. Secondary predictive variables included sex, age, indications for TMJ replacement, preoperative occlusion, condition of the glenoid fossa and/or condyle, shortening of the mandibular ramus, sagittal mandible position, lateral chin deviation, shape of the coronoid process, and type of surgery. RESULTS: The mean preoperative MIO was 13.0 ±8.0 mm, while the mean MIO 1 month after surgery was 20.6 ±5.5 mm, which was not statistically significant. However, at a later follow-up, functional parameters showed a significant improvement (p = 0.003), with a mean MIO of 32.5 ±5.0 mm 3 years after surgery. Statistical analysis indicated that the initial mouth opening is the strongest predictor of long-term functional recovery after TMJ replacement. Postoperative complications occurred in 4 cases (12.9%) following patient-specific endoprosthesis (PSE) placement. CONCLUSIONS: The use of PSEs for TMJ replacement has enabled the restoration of anatomical relationships in complex clinical cases and an improvement in mouth opening. The preoperative MIO was the only factor that significantly influenced long-term functional outcomes.
RESUMEN
OBJECTIVES: Severe maxillofacial space infection (MSI) as an end stage of dentoalveolar diseases or complication of sialadenitis is a potentially life-threatening disease accompanied by complications including airway obstruction, jugular vein thrombosis, descending mediastinitis, sepsis and acute respiratory distress syndrome. The aim of this study was to analyze the incidence and time trends of severe MSI and potentially influencing factors in the German healthcare system over time. MATERIALS AND METHODS: Nationwide data regarding the national diagnosis-related-group (DRG) inpatient billing system was received from the German Federal Statistical Office. A retrospective analysis of incidence and time trends of MSI-associated procedures classified with the Operation and Procedure Classification System (OPS), were statistically evaluated using Poisson regression analysis between 2005 and 2022 and were associated with different epidemiological factors. RESULTS: The total standardized incidence rate of MSI-associated procedures in the observational period 2005-2022 was 9.8 (â8.2; â11.4) per 100,000 person years. For all age groups a significant increase of 46.1% in severe MSI - related surgical interventions was registered within the observational period. The largest increase (120.5%) was found in elderly patients over 80 years. There were significant differences of the incidences of MSI-associated surgeries between the different federal states in Germany. CONCLUSIONS: Severe MSI are a growing challenge in German health care especially among elderly patients over 80 years. CLINICAL RELEVANCE: Severe MSI is a promising target for prevention. There should be more focus in primary dental and medical care especially in groups depending on social support.

PURPOSE: The COVID-19 pandemic has affected the personal and social lives of millions of people and also impacted the etiological factors of midfacial trauma such as falls, interpersonal violence or traffic accidents. The aim of this study was to analyze the influence of the COVID-19 pandemic on maxillofacial trauma surgery in the German healthcare system. METHODS: Nationwide data regarding the national diagnosis-related-group (DRG) inpatient billing system used in all German hospitals was received from the German Federal Statistical Office. Various trauma-associated procedures of the Operation and Procedure Classification System (OPS), a German modification of the International Classification of Medical Procedures (ICPM), were statistically associated with different epidemiological factors between 2012 and 2021. RESULTS: A statistically significant decrease (p < 0.05) in surgeries regarding maxillofacial fractures was registered during the years 2020 and 2021. Young male patients had the largest decline in maxillofacial trauma surgeries during this period (p < 0.05). In contrast. elderly patients 80 years and older showed a dramatic increase in the frequency of fractures in both the midface and the mandible (p < 0.05). CONCLUSIONS: During the COVID 19 pandemic there has been a shift in the number, composition and etiology of maxillofacial fracture surgeries. Measures of social distancing and personal risk avoidance had a societal positive effect on the frequency of facial injuries. This stands in contrast to the drastic increase in fractures of elderly people who should be protected primarily by the measures taken. These results can help to understand these influences better in future pandemics. TRIAL REGISTRATION: German Clinical Trials Register No: DRKS00032778.

OBJECTIVES: Oral potentially malignant disorders (OPMDs) are the most clinically relevant precursor lesions of the oral squamous cell carcinoma (OSCC). OSCC is one of the 15 most common cancers worldwide. OSCC is with its high rate of mortality an important cause of death worldwide. The diagnosis and therapy of clinically relevant precursor lesions of the OSCC is one of the main parts of prevention of this malignant disease. Targeted therapy is one of the main challenges concerning an oncologically safe tissue removal without overwhelming functional and aesthetic impairment. MATERIALS AND METHODS: In this randomized controlled trial, a newly introduced intraoral 445-nm semiconductor laser (2W; cw-mode; SIROLaser Blue, Dentsply Sirona, Bensheim, Germany) was used in the therapy of OPMDs. Duration and course of wound healing, pain, and scar tissue formation were compared to classical cold blade removal with primary suture by measuring remaining wound area, tissue colorimetry, and visual analogue scale. The study includes 40 patients randomized using a random spreadsheet sequence in two groups (n1 = 20; n2 = 20). RESULTS: This comparative analysis revealed a significantly reduced remaining wound area after 1, 2, and 4 weeks in the laser group compared to the cold blade group (p < 0.05). In the laser group, a significantly reduced postoperative pain after 1 week was measured (p < 0.05). CONCLUSION: Laser coagulation of OPMDs with the investigated 445-nm semiconductor laser is a safe, gentle, and predictable surgical procedure with beneficial wound healing and reduced postoperative discomfort. CLINICAL RELEVANCE: Compared to the more invasive and bloody cold blade removal with scalpel, the 445-nm semiconductor laser could be a new functional less traumatic tool in the therapy of OPMDs. The method should be further investigated with regard to the identification of further possible indications. TRAIL REGISTRATION: German Clinical Trials Register No: DRKS00032626.

Prolonged operation times should be avoided due to the associated complications and negative effects on the efficiency of the use of operating room resources. Surgical treatment of mandibular condylar head fractures is a well-established routine procedure at our department, nevertheless, we recognized fluctuating operating times. This study aims to pinpoint the influencing factors, in particular the hypothesis whether the efficiency of intraoperative muscle relaxation may decisively affect the duration of surgery. It analyses 168 mandibular condylar head fractures that were surgically treated in the period from 2007 to 2022 regarding the duration of the surgery and potential factors affecting it. The potential predictors' influence on the dependent variable operation time was mainly calculated as a bivariate analysis or linear regression. Efficiency of relaxation (p ≤ 0.001), fragmentation type (p = 0.031), and fracture age (p = 0.003) could be identified as decisive factors affecting the duration of surgery, as the first surgeon was a constant. In conclusion, surgical intervention should start as soon as possible after a traumatic incident. In addition, a dosage regimen to optimize the efficiency of relaxation should be established in future studies. Fragmentation type and concomitant fractures should also be considered for a more accurate estimation of the operating time.
RESUMEN
PURPOSE: The objective of this study was to demonstrate the suitability of cone-beam computed tomography (CBCT) for in vivo research in periodontology, with implications for oral implantology, facial traumatology, and all disciplines involved in treating patients with bisphosphonate-related osteonecrosis of the jaw (BRONJ). METHODS: Halves of the jaws of 9 Swiss mountain sheep, assigned to a control group (n=3), an osteoporosis group (n=3) and a zoledronate-exposed group (n=3), were examined. Clinical and radiological evaluations were conducted using CBCT imaging to assess whether periodontitis and bone defects were observed to a significant extent after surgical tooth extraction. RESULTS: In contrast to the control and osteoporosis groups, the zoledronate group exhibited significant residual bone defects following tooth extraction (P<0.05). CBCT more objectively revealed these effects and enabled a numerical evaluation (in mm3). CONCLUSIONS: Evaluating residual defects in bone blocks from sheep using CBCT analysis was found to be as effective as a clinical examination conducted by specialists in oral and maxillofacial surgery. The strong correlation between radiological findings and clinical conditions suggests that CBCT may become increasingly important in the future, particularly in periodontological research related to BRONJ.
RESUMEN
Idiopathic condylar resorption (ICR), though a rare event, is associated with severe detrimental sequelae for the patient. To date, the etiology remains unknown, and treatment strategies are highly controversial. Therefore, the aim of this study is to present an analysis of the consensus- and evidence-based approach to ICR by a German interdisciplinary guideline project of the AWMF (Association of the Scientific Medical Societies in Germany). Following a systematic literature search, including 56 (out of an initial 97) publications, with a predominantly low level of evidence (LoE), two independent working groups (oral and maxillofacial surgery and interdisciplinary, respectively) voted on a draft comprising 25 recommendations in a standardized anonymized and blinded Delphi procedure. While the results of the votes were relatively homogeneous, the interdisciplinary phase required a significantly higher number of rounds (p < 0.001). Most of the controversial recommendations were related to initial imaging (with consensus on CT/CBCT as the current diagnostic standard for imaging), pharmacotherapy (no recommendation due to lack of evidence), discopexy (no recommendation possible due to low LoE) and timing of orthognathic surgery (with consensus on two-staged procedures after invasive TMJ surgery, except for single-stage procedures if combined with total joint reconstruction). Overall, the Delphi procedure resulted in an interdisciplinary guideline offering the best possible evidence- and consensus-based expertise to date in the diagnosis and treatment of ICR.
RESUMEN
PURPOSE: Using network meta-analyses (NMA) has become increasingly valuable as it enables the comparison of interventions that have not been directly compared in a clinical trial. To date, there has not been a NMA of randomized clinical trials (RCT) that compares all types of treatments for mandibular condylar process fractures (MCPFs). The aim of this NMA was to compare and rank all the available methods used in the treatment of MCPFs. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic search was conducted in 3 major databases up to January 2023 to retrieve RCTs that compared various closed and open treatment methods for MCPFs. The predictor variable is treatment techniques: arch bars (ABs) + wire maxillomandibular fixation (MMF), rigid MMF with intermaxillary fixation screws, AB + functional therapy with elastic guidance (AB functional treatment), AB rigid MMF/functional treatment, single miniplate, double miniplate, lambda miniplate, rhomboid plate, and trapezoidal miniplate. Postoperative complications were the outcome variables and included occlusion, mobility, and pain, among other things. Risk ratio (RR) and standardized mean difference were calculated. Version 2 of the Cochrane risk-of-bias tool and Grading of Recommendations, Assessment, Development, and Evaluations system were used to determine the certainty of the results. RESULTS: The NMA included a total of 10,259 patients from 29 RCTs. At ≤6 months, the NMA revealed that the use of 2-miniplates significantly reduced malocclusion compared to rigid MMF (RR = 2.93; confidence interval [CI]: 1.79 to 4.81; very low quality) and functional treatment (RR = 2.36; CI: 1.07 to 5.23; low quality).Further, at ≥6 months, 2-miniplates resulted in significantly lower malocclusion compared to rigid MMF with functional treatment (RR = 3.67; CI: 1.93 to 6.99; very low quality).Trapezoidal plate and AB functional treatment were ranked as the best options in 3-dimensional (3D) plates and closed groups, respectively.3D-miniplates (very low-quality evidence) were ranked as the most effective treatment for reducing postoperative malocclusion and improving mandibular functions after MCPFs, followed closely by double miniplates (moderate quality evidence). CONCLUSIONS: This NMA found no substantial difference in functional outcomes between using 2-miniplates versus 3D-miniplates to treat MCPFs (low evidence).However, 2-miniplates led to better outcomes than closed treatment (moderate evidence).Additionally, 3D-miniplates produced better outcomes for lateral excursions, protrusive movements, and occlusion than closed treatment at ≤6 months (very low evidence).

Objectives: To examine outcomes of the coronal scalp approach to craniomaxillofacial (CMF) fractures performed by oral-maxillofacial or craniofacial plastic surgery residents (OMFS/CFPS-Rs) vs. trauma surgery residents (TS-Rs), and to determine differences in treatment outcomes between both operator groups. Methods: This retrospective cohort study enrolled a sample of CMF fracture adult patients treated via the coronal approach in a German level one trauma center during a two-year interval. The predictor variable was training background (OMFS/CFPS-Rs vs. TS-Rs; each n = 5). All trainees must assist in ≥ two surgeries before self-performance. The main outcomes were length of hospital stay (LHS) and coronal flap-related complications (CFRCs). Appropriate statistics were computed at α = 95%. Results: Of the 97 patients identified during the study period; 71 of whom (19.7% females; mean age, 40.2 ± 15.2 years; 46.5% operated by TS-Rs; 38% combined upper and midfacial fractures) met the inclusion criteria. Operative time, LHS, CFRCs, readmission rates, and post-discharge emergency room visits were not significantly different between the trainee groups. 60% of CFRCs were visible/unfavorable or hypertrophic scar with/without alopecia. The number needed to treat of short LHS was 44 (95% confidence interval [CI], 3.9 to 4.8), the number needed to harm of CFRCs was 14 (95% CI, 3.6 to 7.4), i.e., the likelihood to be helped or harmed was 0.32. Conclusions: Coronal flap raising by OMFS/CFPS-Rs does not appear beneficial over that by TS-Rs in terms of LHS and CFRCs evaluated until postoperative month six. Trainees from any surgical specialties could gain partial independence from skilled surgeons in CMF trauma "sub-steps" and favorable clinical outcomes. Further studies in a larger sample cohort are required to confirm this pilot data.
RESUMEN
(1) Background: Evaluation of impact of adjuvant radiation therapy (RT) in patients with oral squamous cell carcinoma of the oral cavity/oropharynx (OSCC) of up to 4 cm (pT1/pT2) and solitary ipsilateral lymph node metastasis (pN1). A non-irradiated group with clinical follow-up was chosen for control, and survival and quality of life (QL) were compared; (2) Methods: This prospective multicentric comprehensive cohort study included patients with resected OSCC (pT1/pT2, pN1, and cM0) who were allocated into adjuvant radiation therapy (RT) or observation. The primary endpoint was overall survival. Secondary endpoints were progression-free survival and QL after surgery; (3) Results: Out of 27 centers, 209 patients were enrolled with a median follow-up of 3.4 years. An amount of 137 patients were in the observation arm, and 72 received adjuvant irradiation. Overall survival did not differ between groups (hazard ratio (HR) 0.98 [0.55-1.73], p = 0.94). There were fewer neck metastases (HR 0.34 [0.15-0.77]; p = 0.01), as well as fewer local recurrences (HR 0.41 [0.19-0.89]; p = 0.02) under adjuvant RT. For QL, irradiated patients showed higher values for the symptom scale pain after 0.5, two, and three years (all p < 0.05). After six months and three years, irradiated patients reported higher symptom burdens (impaired swallowing, speech, as well as teeth-related problems (all p < 0.05)). Patients in the RT group had significantly more problems with mouth opening after six months, one, and two years (p < 0.05); (4) Conclusions: Adjuvant RT in patients with early SCC of the oral cavity and oropharynx does not seem to influence overall survival, but it positively affects progression-free survival. However, irradiated patients report a significantly decreased QL up to three years after therapy compared to the observation group.
RESUMEN
PURPOSE: To measure the association between drainage use and postoperative complications (POCs) after posttraumatic ear reconstruction (PTER) with Dieffenbach's postauricular flap (DPF) in patients with antithrombotic therapy (ATT). METHODS: This was a retrospective double-cohort study of patients undergoing posttraumatic DRF with vs. without drainage in 4 maxillofacial units during a 7-year interval. The primary predictor variable was drainage use, and the main outcome was POCs (i.e., auricular haematoma and infection). Descriptive, bi- and multivariate statistics were computed with P ≤ 0.05 defined as statistically significant. RESULTS: The sample was composed of 365 unilateral PTER patients (14% POCs, 15.6% ATT, 34.5% females) aged 58.1 ± 19.7 years (range, 18-101). Among subjects with ATT, drainage use significantly reduced POCs (OR, 0.5; 95% CI, 0.3 to 0.8; P = 0.009; absolute risk reduction [ASR], 34.04%; NNT, 3), especially when delayed surgery > 5 h after trauma was evident (forward stepwise logistic modelling: OR, 20.6; 95% CI, 2 to 215.9; P = 0.012). Drainage placement under DPF in ATT patients with smoking habit, concomitant diseases (e.g. diabetes mellitus), ear cartilage loss, or wound contamination almost halved POC rates (ASR, 34.5 ± 12.1%; range, 22.1% to 49%). Patient's age, gender, American Society of Anesthesiologists (ASA) class, alcohol misuse, ATT and antibiotic type, and international normalised ratio (INR) before surgery had no meaningful effect on POCs. CONCLUSIONS: Drainage should be placed under DPF in patients with ATT, regardless of age, gender, ATT and antibiotic type, and preoperative INR.

PURPOSE: For nearly four decades, submental intubation (SI) has been introduced and employed to avoid tracheostomy in facial trauma cases where nasal/oral intubation is infeasible or associated with possible risks. The purposes of this study were to estimate the frequency and to identify variables associated with complications of SI (CSI). METHODS: The authors organised a retrospective cohort study and enrolled a group of patients with facial trauma and SI during a seven-year interval at two German level one trauma centres where SI has routinely been used in complex facial trauma cases. The predictor variables included demographic, medical, dental, fracture-related, operative, and postoperative parameters. The outcome variable was CSI. We used descriptive, bivariate, and multivariate analyses at the 0.05 significant level. RESULTS: The sample included 339 patients (24.5% females, 9.4% had complications) with an average age of 58.2 ± 12.0 years (range, 17-89). Bivariate analyses revealed nine significant variables. However, forward stepwise multiple logistic regression modelling identified three variables statistically associated with CSI: smoking (OR, 691.8; 95% CI, 75.9 to 6303.9; P < 0.0001; number needed to harm [NNH], 6), moderate to high gingival inflammation (OR, 786.7; 95% CI, 66 to 9378.9; P = 0.002; NNH, 12), and postoperative use of chlorhexidine mouthwash (OR, 0.03; 95% CI, 0.001 to 0.77; P = 0.0003; number needed to treat [NNT], 2). CONCLUSIONS: smokers and subjects with gingivitis were more likely to experience CSI. Postoperative chlorhexidine rinsing was the potentially modifiable, albeit low-OR, factor. These findings could help to draw an effective guideline against the CSI.

OBJECTIVES: To assess the relationship between orbital wall fractures connecting to paranasal sinuses (OWF-PNS) and SARS-CoV-2 ocular surface contamination (SARS-CoV-2-OSC) in asymptomatic COVID-19 patients. METHODS: This was a prospective case-control study enrolling two asymptomatic COVID-19 patient cohorts with vs. without OWF-PNS in the case-control ratio of 1:4. All subjects were treated in a German level 1 trauma center during a one-year interval. The main predictor variable was the presence of OWF-PNS (case/control); cases with preoperative conjunctival positivity of SARS-CoV-2 were excluded to rule out the possibility of viral dissemination via the lacrimal gland and/or the nasolacrimal system. The main outcome variable was laboratory-confirmed SARS-CoV-2-OSC (yes/no). Descriptive and bivariate statistics were computed with a statistically significant P ≤ 0.05. RESULTS: The samples comprised 11 cases and 44 controls (overall: 27.3% females; mean age, 52.7 ± 20.3 years [range, 19-85]). There was a significant association between OWF-PNS and SARS-CoV-2-OSC (P = 0.0001; odds ratio = 20.8; 95% confidence interval = 4.11-105.2; R-squared = 0.38; accuracy = 85.5%), regardless of orbital fracture location (orbital floor vs. medial wall versus both; P = 1.0). CONCLUSIONS: Asymptomatic COVID-19 patients with OWF-PNS are associated with a considerable and almost 21-fold increase in the risk of SARS-CoV-2-OSC, in comparison with those without facial fracture. This could suggest that OWF-PNS is the viral source, requiring particular attention during manipulation of ocular/orbital tissue to prevent viral transmission.

PURPOSES: To evaluate clinical usefulness of endoscope-assisted medial orbital wall fracture repair via the retrocaruncular approach (rc-EAMOWFR) vs. no surgery (NS), and to perform a narrative review of relevant literature. METHODS: This was a retrospective cohort study enrolling isolated medial orbital wall fracture (IMOWF) eyes presented to two German level 1 trauma centers during a 7-year interval. The predictor variable was treatment type (rc-EAMOWFR vs. NS), and the main outcomes were late enophthalmos (LE) and retrobulbar hemorrhage (RH) assessed at 9-15 posttraumatic months. Descriptive and bivariate statistics were computed at α = 95%. Binary adjustments enabled calculation of number needed to treat (NNT), to harm (NNH), and likelihood to be helped or harmed (LHH) for demonstrating benefit-risk tradeoffs. Moreover, a narrative review was also performed. RESULTS: The sample comprised 502 patients (28.3% females; mean age, 46.5±19.2 years) with 541 IMOWF eyes (5.9% NS; 7.2% LE; 1.3% RH). Operated eyes had significantly lower LE events than NS eyes (symptomatic IMOWF: P < .0001; 95% confidence interval [CI], .03 to .16; NNT = 2 [95% CI, 1.1 to 6.1]; asymptomatic IMOWF: P < .0001; 95% CI, .01 to .07; NNT = 2 [95% CI, 1.1 to 1.8]). There were 7 (1.5%) RH events following rc-EAMOWFR (P = .99; 95% CI, .06 to 17.4; NNH = 68 [95% CI, 38.3 to 254.2]). LHH calculations posited that rc-EAMOWFR was 34 times more likely to prevent LE than to cause RH, regardless of fracture symptoms. Our results conformed to those of other 15 studies. CONCLUSIONS: The results of this study suggest that all IMOWFs be treated. rc-EAMOWFR performed in every 68 IMOWFs would be at risk of one RH event, but prevent 34 eyes from LE due to untreated fractures. Nearly 72% of untreated IMOWFs develop LE after 9 months.

Patients with angiotensin-converting enzyme inhibitor (ACEI)-induced angioedema (ACEIIA) may visit family physicians. The aim of this article was to describe a case of delayed-onset ACEIIA and to present a concise scoping review. Using a case report and a scoping review study design, we report a case of ACEIIA, with clinically confirmed diagnosis. The symptoms resolved after replacing the offending ACEI with another antihypertensive agent. After excluding other causes of perioral swelling and discontinuation of ACEI, the patient was symptom-free within a few days thereafter. Based on this case presentation, we performed a meta-narrative scoping review including up-todate diagnosis and management of ACEIIA, based on published data in English, French, and German from inception to April 1, 2021. Patients with angioedema of unknown origin should be cautiously examined to rule out oral diseases, including allergy to dental materials and drug-induced angioedema. Clinicopathological aspects and current treatment guidelines for ACEI-associated angioedema are also presented.
RESUMEN
PURPOSE: To answer the following clinical research question: "Among patients with multiple basal cell carcinomas (mBCCs), can panoramic radiograph (PaR) facilitate the diagnosis of Gorlin-Goltz syndrome (GGS)?" METHODS: This retrospective study enrolled mBCCs subjects who presented to a German tertiary care center between 1 January 2015 and 31 December 2021. The primary predictor was presence of syndromic mBCCs, and the main outcomes were jaw cysts and odontogenic keratocysts (OKCs). Descriptive, bi- and multivariate statistics, diagnostic test evaluation, and number needed to screen (NNS) were computed at α = 95%. RESULTS: The sample comprised 527 mBCCs patients (36.1% females; 6.8% GGS; 5.5% OKCs; mean age, 74.5 ± 15.8 years [range, 15-102]). There was a significant association between syndromic mBCCs and jaw cysts (P < .0001; NNS = 2 [95% CI, CI, 1.1 to 1.4]). In the adjusted logistic model, PaR identified GGS via radiographic diagnosis of jaw cysts in case of 1) age ≤ 35 years, 2) ≥ 5 BCCs, and 3) ≥ 1 high-risk BCCs. Nearly every jaw cyst identified by PaR was OKCs (P = .01; 95% CI, 3.1 to 3,101.4; NNS = 1.3 [95% CI, .9 to 2]). The post hoc power was 100%. CONCLUSIONS: Dental screening with the use of PaR for mBCCs patients, especially those aged ≤35 years, or with ≥5 BCCs, or ≥1 high-risk BCCs, may be helpful in detection and identification of GGS through recognition of OKCs.
