Outcomes of Radial Forearm Free Flap Closure With Split-Thickness Skin Graft Versus Primary Closure.

BACKGROUND: This study compares patient-reported functional and aesthetic outcomes of split-thickness skin graft (STSG) versus hatchet flap closure of radial forearm free flap (RFFF) donor site. METHODS: Patients with RFFF (2015-2020) were retrospectively identified. Those willing to participate in patient-reported outcomes (PRO) filled out Patient-Observer Scar Assessment Scale (POSAS) and Michigan Hand Outcome Questionnaire (MHOQ). RESULTS: 198 patients met our inclusion criteria and 81 participated in PRO. There was a higher rate of tendon exposure in STSG versus hatchet flap (11 vs. 1, p = 0.0019), but a lower rate of skin necrosis (5 vs. 16, p = 0.0190) and epidermolysis (1 vs. 12, p = 0.0028). Scar quality in STSG was superior to hatchet flap in all domains of POSAS. MHOQ scores were similar between both groups with no statistical difference in overall scores (p = 0.2165). CONCLUSIONS: STSG appeared to have less compromise in activities of daily living, better satisfaction and improved scar quality than hatchet flap, but a higher rate of tendon exposure.

Designing a muon scattering scanner for nuclear debris measurement.

Removal of fuel debris is planned to start at Unit 2 of the Fukushima Daiichi Nuclear Power Plant. During the removal, it is desirable to distinguish fuel debris from radioactive wastes and to sort the fuel debris accordingly to the amounts of nuclear material contained. Muon scattering tomography invented at Los Alamos in the early 2000s is highly sensitivity to high-atomic-number materials such as uranium. A muon scanner to sort the debris is designed and currently in production. One of the challenges is to operate the muon scanner in the presence of high γ-ray radiations from the debris: muon-event-identification electronics and a muon-tracking algorithm in the presence of high γ-ray radiations were developed.

Barriers to Accessing Primary Dental Care in Adults with Alcohol Dependence: A Qualitative Study.

BACKGROUND: People with alcohol dependence (AD) frequently experience oral health problems, but their dental attendance is poor, with limited evidence to the reasons why from their perspective. OBJECTIVE: To explore perceived barriers, motivators, and facilitators to accessing primary dental care in people with AD. METHODS: Qualitative study consisting of remote one-to-one and group semistructured interviews with a convenience sample of adults with lived experience of AD in northern England. Data were audio-recorded, transcribed, and coded. A reflexive thematic analysis method was used; use of COM-B model informed data interpretation. RESULTS: Twenty adults with lived experience of AD participated in 18 one-to-one interviews and 1 group interview (of 3 participants). Barriers to access were fear and physical, social, and environmental factors (physical effects of AD, financial barriers, nonprioritization of oral health). Motivators to access were pain and prioritization of oral health. Facilitators to access were patterns of alcohol use (i.e., sobriety) and dental service provision within recovery services. CONCLUSIONS: Fear of "the dentist" is a major barrier to accessing dental care, and pain is the primary motivator, among people with AD, although neither are unique to this population. Fear and physical, social, and environmental barriers to access contribute to problem-oriented attendance, which negatively affect oral health outcomes. Opportunity to facilitate attendance increases when a person is in remission from AD through their physical capabilities improving. Increasing capability and opportunity can influence attendance beyond the automatic motivation of pain. Provision of dental care within recovery services could facilitate access to care. Understanding the "web of causation" is key to developing any intervention to improve dental access in people with AD. Further research is needed from the perspective of other adult populations with lived experience of AD, as well as of dental professionals, to gain deeper insight into barriers, facilitators, and possible solutions. KNOWLEDGE TRANSFER STATEMENT: The results of this study can help dental professionals understand factors affecting access to primary care in people with alcohol dependence to provide knowledge that may reduce stigma surrounding the disease. Results also demonstrate areas for intervention development for public policy.

Filling in the Gaps. Making Sense of Living with Temporomandibular Disorders: A Reflexive Thematic Analysis.

INTRODUCTION: Persistent, painful temporomandibular disorders (TMDs) are challenging to manage and usually require the active engagement of patients. To achieve this, it is necessary to understand the complex and multifactorial nature of persistent pain. Many dental professionals have little education about persistent pain and may prefer to offer structural management and advice. This research aims to explore how people understand their persistent TMD and how this understanding has been influenced by their treatment providers. METHODS: Twenty-one people were recruited to represent a diversity of experience with persistent TMD. Interviews followed a semistructured topic guide. Themes were constructed through reflexive thematic analysis to represent how people made sense of their symptoms and the messages that they had picked up through their treatment journey. RESULTS: Participants described examples of conflicting opinions and inconsistent management recommendations. They rarely recalled collaborative discussions about the nature and complexity of their symptoms and different options for treatment. This experience is represented by a single theme, "a medical merry-go-round." Subthemes of "a medical journey to nowhere-participants' frustrated attempts to find medical management that will end their pain" and "is it me?-participants' questioning their role in persisting pain" kept participants on the merry-go-round, while symptom resolution and participants' emerging development of a holistic understanding of their TMD pain provided exit points. Understanding pain holistically tended to be helpful and typically occurred despite rather than because of the advice given in routine treatment settings. CONCLUSION: Participants in this study had not typically found their pain management within dental and medical settings to have helped them to construct meaning and understand their experiences of painful TMD. However, understanding symptoms holistically was experienced as beneficial. This study suggests that improved communication and signposting within services for persistent TMD may be beneficial to patients with TMD pain. KNOWLEDGE TRANSFER STATEMENT: Results of this study confirm that being offered a series of anatomically based, singular-cause explanations for persisting pain symptoms had been experienced as unhelpful by the participants who had sought help for their TMD. Participants highlighted the importance of accurate and collaborative communication and of dental professionals explicitly adopting and communicating a biopsychosocial understanding of pain to their patients who have TMD. Results highlight that some people can struggle to manage persisting pain with minimal support. Signposting patients to appropriate services and resources may help them to understand more about the nature of persistent pain and methods of managing it.

Simulation and validation studies of a large drift tube muon tracker.

Cosmic ray muons are massive, charged particles created from high energy cosmic rays colliding with atomic nuclei in Earth's atmosphere. Because of their high momenta and weak interaction, these muons can penetrate through large thicknesses of dense material before being absorbed, making them ideal for nondestructive imaging of objects composed of high-Z elements. A Giant Muon Tracker with two horizontal 8 × 6 in.2 and two vertical 6 × 6 in.2 modules of drift tubes was used to measure muon tracks passing through samples placed inside the detector volume. The experimental results were used to validate a Monte Carlo simulation of the Giant Muon Tracker. The imaging results of simulated samples were reconstructed and compared with those from the experiment, which showed excellent agreement.

The Longitudinal Relationship between Jaw Catching/Locking and Pain.

Orofacial pain and joint-related dysfunction can negatively affect daily jaw function. A common cause for limitations in jaw movements is joint-related dysfunction such as various forms of catching and locking. However, knowledge is limited regarding the development and natural course of joint-related jaw dysfunction and its relationship to the onset and course of orofacial pain. Therefore, the aim was to evaluate the incidence, prevalence, and gender differences in jaw catching/locking over time and in relation to orofacial pain in the general population. Data from 3 validated screening questions on orofacial pain and jaw catching/locking were collected from all routine dental checkups in the Public Dental Health Services in Västerbotten, Sweden, from 2010 to 2017. Logistic generalized estimating equation was used to account for repeated observations and Poisson regression for incidence analysis. In total, 180,308 individuals (aged 5-104 y) were screened in 525,707 dental checkups. In 2010, based on 37,647 individuals, the prevalence of self-reported catching/locking was higher in women than in men (3.2% vs. 1.5%; odds ratio, 2.11; 95% confidence interval [CI], 1.83-2.43), and this relationship and magnitude remained similar throughout the study period. The annual incidence rate was 1.1% in women and 0.5% in men. Women were at a higher risk than men for reporting both first onset (incidence rate ratio [IRR], 2.29; 95% CI, 2.11-2.49) and persistent (IRR, 2.31; 95% CI, 2.04-2.63) catching/locking. For the onset subcohort (n = 135,801), an independent onset of orofacial pain or jaw catching/locking exclusively was reported by 84.1%, whereas a concurrent onset was reported by 13.4%. Our findings of higher incidence, prevalence, and persistence in women than in men indicate that the gender differences seen for orofacial pain are evident also for jaw catching/locking. The findings also suggest independent onset of self-reported catching/locking and orofacial pain, which reinforces the pathophysiological differences between these conditions.

Persistent Orofacial Pain Attendances at General Medical Practitioners.

Patients with persistent orofacial pain (POFP) can go through complex care pathways to receive a diagnosis and management, which can negatively affect their pain. This study aimed to describe 44-y trends in attendances at Welsh medical practices for POFP and establish the number of attendances per patient and referrals associated with orofacial pain and factors that may predict whether a patient is referred. A retrospective observational study was completed using the nationwide Secure Anonymised Information Linkage Databank of visits to general medical practices in Wales (UK). Data were extracted using diagnostic codes ("Read codes"). Orofacial and migraine Read codes were extracted between 1974 and 2017. Data were analyzed using descriptive statistics and univariate and multivariable logistic regression. Over the 44-y period, there were 468,827 POFP and migraine diagnostic codes, accounting for 468,137 patient attendances, or 301,832 patients. The overall attendance rate was 4.22 attendances per 1,000 patient-years (95% confidence interval [CI], 4.21-4.23). The attendance rate increased over the study period. Almost one-third of patients (n = 92,192, 30.54%) attended more than once over the study period, and 15.83% attended more than once within a 12-mo period. There were 20,103 referral codes that were associated with 8,183 patients, with over half these patients being referred more than once. Odds of receiving a referral were highest in females (odds ratio [OR], 1.23; 95% CI, 1.17-1.29), in those living in rural locations (OR, 1.17; 95% CI, 1.12-1.22), and in the least deprived quintile (OR, 1.39; 95% CI, 1.29-1.48). Odds also increased with increasing age (OR, 1.03; 95% CI, 1.03-1.03). The increasing attendance may be explained by the increasing incidence of POFP within the population. These patients can attend on a repeated basis, and very few are referred, but when they are, this may occur multiple times; therefore, current care pathways could be improved.

Patient-reported outcomes and morbidity after head and neck reconstructions: An evaluation of fibular and scapular free flaps.

BACKGROUND: Fibular (FFF) and scapular free flaps (SFF) are versatile tissue transfers for head and neck reconstruction. However, their relative morbidity has been sparsely studied. The primary goal of this study was to evaluate the morbidity and patient-reported outcome measures of these two reconstructive options. MATERIALS AND METHODS: Case series of patients from 2017 to 2020 who underwent a FFF or SFF for head and neck ablation. Demographic and surgical outcome measures, such as Charlson Comorbidity Index (CCI), anesthetic time, donor site morbidity, and perioperative morbidity score (POMs) were extracted. Patients were contacted to complete the Decision Regret Scale (DRS), University of Washington Quality of Life (UW-QoL), Oral Health Impact-14, and limb specific functional outcome measures. Statistical analyses included a linear regression. RESULTS: In total, 97 FFF (mean age 58.5, 62.9% male) and 55 SFF (mean age 64.8, 63.6% male) were included. Total surgical time was higher in the SFF group (p < 0.05) and they had more comorbidities (p < 0.01). SFF patients had lower POM scores on post-operative day three (p < 0.05) while FFF patients scored better on the UW-QoL Physical Domain (p < 0.01). The DRS for both groups (FFF mean DRS 22.7, SFF mean DRS 19.2) was similar. When adjusted for patient morbidity, however, the SFF group had less decisional regret (p < 0.05). CONCLUSION: This is the largest comprehensive evaluation of patient-reported outcome measures for FFF and SFFs. SFFs required longer surgical times but had less early morbidity than FFFs. Patients who underwent either reconstructions reported mild decisional regret, proving these are generally well tolerated procedures.

Waterline Disinfectants Reduce Dental Bioaerosols: A Multitracer Validation.

Oral microbes are dispersed during dental treatment and reduction methods have been proposed, but dental unit waterline (DUWL) disinfectants have received little attention; specifically, the effect on viruses has not been studied. This study aims to 1) investigate the effect of DUWL disinfectants on viral dispersion in dental bioaerosols and 2) establish a dual-tracer system using live bacteriophage and fluorescein supported by optical particle measurement. Bacteriophage MS2 was used as a viral tracer and fluorescein as a fluorescent tracer. Validation experiments were conducted to exclude interference of one tracer with the other or of DUWL disinfectants on detection methods. Simulated "saliva" containing the tracers was infused into the mouth of a dental mannequin during 10-min dental procedures with an air turbine handpiece (n = 3 replicates). Aerosols and droplets were sampled in an enclosed dental operatory using air samplers and settlement onto sterile filter papers. Bacteriophage was quantified using plaque assays and reverse transcription quantitative polymerase chain reaction (RT-qPCR). Fluorescein was quantified fluorometrically. The effect of DUWL disinfectants on total aerosol concentration was assessed in separate experiments using an optical particle counter. DUWL disinfectants reduced bacteriophage viability, and interference between tracers was not observed. In simulated clinical procedures, the disinfectant ICX reduced bacteriophage detection substantially (P < 0.001; 2-way analysis of variance). MS2 RNA was detected in all experimental samples but not negative controls. Samples positive on RT-qPCR but not plaque assays may indicate that virions at distant sites are nonviable. Fluorescein tracer showed good agreement with the bacteriophage tracer. DUWL disinfectants designed for continuous presence in irrigants reduce the dispersion of viable virus in dental bioaerosols during simulated procedures. Their use may therefore be important for routine infection control and as a mitigation factor during infectious disease outbreaks. Future studies should explore this using a range of viruses and other microbes.

Dental Attendances to General Medical Practitioners in Wales: A 44 Year-Analysis.

One-third of the UK population is composed of problem-oriented dental attenders, seeking dental care only when they have acute dental pain or problems. Patients seek urgent dental care from a range of health care professionals, including general medical practitioners. This study aimed to identify trends in dental attendance at Welsh medical practices over a 44-y period, specifically in relation to dental policy change and factors associated with repeat attendance. A retrospective observational study was completed via the nationwide Secure Anonymised Information Linkage (SAIL) Databank of visits to general medical practice in Wales. Read codes associated with dental diagnoses were extracted for patients attending their general medical practitioner between 1974 and 2017. Data were analyzed with descriptive statistics and univariate and multivariable logistic regression. Over the 44-y period, there were 439,361 dental Read codes, accounting for 288,147 patient attendances. The overall attendance rate was 2.60 attendances per 1,000 patient-years (95% CI, 2.59 to 2.61). The attendance rate was negligible through 1987 but increased sharply to 5.0 per 1,000 patient-years in 2006 (95% CI, 4.94 to 5.09) before almost halving to 2.6 per 1,000 in 2017 (95% CI, 2.53 to 2.63) to a pattern that coincided with changes to National Health Service policies. Overall 26,312 patients were repeat attenders and were associated with living in an area classified as urban and deprived (odds ratio [OR], 1.22; 95% CI, 1.19 to 1.25; P < 0.0001) or rural (OR, 0.84; 95% CI, 0.83 to 0.85; P < 0.0001). Repeat attendance was associated with greater odds of having received an antibiotic prescription (OR, 2.53; 95% CI, 2.50 to 2.56; P < 0.0001) but lower odds of having been referred to another service (OR, 0.75; 95% CI, 0.70 to 0.81; P < 0.0001). Welsh patients' reliance on medical care for dental problems was influenced by social deprivation and health policy. This indicates that future interventions to discourage dental attendance at medical practitioners should be targeted at those in the most deprived urban areas or rural areas. In addition, health policy may influence attendance rates positively and negatively and should be considered in the future when decisions related to policy change are made.

Local Exhaust Ventilation to Control Dental Aerosols and Droplets.

Dental procedures produce aerosols that may remain suspended and travel significant distances from the source. Dental aerosols and droplets contain oral microbes, and there is potential for infectious disease transmission and major disruption to dental services during infectious disease outbreaks. One method to control hazardous aerosols often used in industry is local exhaust ventilation (LEV). The aim of this study was to investigate the effect of LEV on aerosols and droplets produced during dental procedures. Experiments were conducted on dental mannequins in an 825.4-m3 open-plan clinic and a 49.3-m3 single surgery. Ten-minute crown preparations were performed with an air-turbine handpiece in the open-plan clinic and 10-min full-mouth ultrasonic scaling in the single surgery. Fluorescein was added to instrument irrigation reservoirs as a tracer. In both settings, optical particle counters (OPCs) were used to measure aerosol particles between 0.3 and 10.0 µm, and liquid cyclone air samplers were used to capture aerosolized fluorescein tracer. In addition, in the open-plan setting, fluorescein tracer was captured by passive settling onto filter papers in the environment. Tracer was quantified fluorometrically. An LEV device with high-efficiency particulate air filtration and a flow rate of 5,000 L/min was used. LEV reduced aerosol production from the air-turbine handpiece by 90% within 0.5 m, and this was 99% for the ultrasonic scaler. OPC particle counts were substantially reduced for both procedures and air-turbine settled droplet detection reduced by 95% within 0.5 m. The effect of LEV was substantially greater than suction alone for the air-turbine and was similar to the effect of suction for the ultrasonic scaler. LEV reduces aerosol and droplet contamination from dental procedures by at least 90% in the breathing zone of the operator, and it is therefore a valuable tool to reduce the dispersion of dental aerosols.

Dyskeratosis Congenita and Squamous Cell Cancer of the Head and Neck: A Case Report and Systematic Review.

OBJECTIVES: Dyskeratosis congenita (DC) is a progressive congenital disorder that predisposes patients to squamous cell cancers (SCC) of the head and neck. We report a case of a patient who underwent primary osteocutaneous free flap for mandibular SCC followed by additional treatments for positive margins and discuss a systematic review on therapeutic management for this patient population. METHODS: Case report of a 39-year-old male with DC who underwent resection and reconstruction with a fibular free flap for mandible SCC, followed by revision surgery and adjuvant radiotherapy for positive margins. A systematic review was completed afterward with the following terms: "dyskeratosis congenita" AND "oral cancer" OR "head and neck" OR "otolaryngology" on Medline and Web of Science for articles between 1980 and 2021. In total, 12 articles were included that reported on DC and SCC in the head and neck. RESULTS: Of the case reports that were included in this review, half the patients had recurrence within 1 year of primary treatments. Only 2 patients did not require revision surgery, adjuvant, or salvage therapy. Half of patients that received radiation therapy had severe side effects. CONCLUSIONS: This is the largest review of DC and SCC in the head and neck. Based off our case report and review, these patients have aggressive disease that often requires multi-modality treatment. Consideration should be taken in regards to reports of side effects with radiation therapy.

DEEP Study: Modeling Outcomes and Costs of Persistent Orofacial Pain.

KNOWLEDGE OF TRANSFER STATEMENT: Despite a substantial number of consultations, individuals experiencing the care pathways in this study continued to have far from perfect health over their life course. The modeling suggests they would only experience 18 y in "perfect health." There is considerable scope to improve current care/outcomes and patient experience.

Effect of Fluorescence Visualization-Guided Surgery on Local Recurrence of Oral Squamous Cell Carcinoma: A Randomized Clinical Trial.

Importance: High local recurrence rates with aggressive disease remain the main concern in oral cancer survival. Use of a translational device using fluorescence visualization (FV) approved by the US Food and Drug Administration and Health Canada, has shown a marked reduction in the 3-year local recurrence rate of high-grade oral lesions in a single-center observational study. Objective: To determine whether FV- guided surgery can improve local control rates in the treatment of in situ or T1 to T2 category oral squamous cell carcinoma (OSCC). Design, Setting, and Participants: A multicenter randomized clinical trial was conducted in a surgical setting. A total of 457 patients were enrolled between January 18, 2010, and April 30, 2015. Data analysis of the intention-to-treat population was performed from April 3, 2019, to March 20, 2020. Patients with histologically confirmed high-grade dysplasia/carcinoma in situ or T1 to T2 category OSCC were randomized to receive traditional peroral surgery or FV-guided surgery. Intervention: Fluorescence visualization during surgery. Main Outcomes and Measures: The primary outcome was local recurrence of OSCC. Secondary outcomes were failure of the first-pass margin, defined as a histologically confirmed positive margin for severe dysplasia or greater histologic change of the main specimen (ie, not the margins taken from the resection bed), regional or distant metastasis, and death due to disease. Results: Of the 457 patients enrolled in the study, 443 patients (264 [59.6%] men; mean [SD] age, 61.5 [13.3] years) completed the randomized treatment: 227 FV-guided and 216 non-FV guided surgery. The median follow-up was 52 (range, 0.29-90.8) months. In total, 45 patients (10.2%) experienced local recurrence. The 3-year local recurrence rate was 9.4% in the FV-guided group and 7.2% in the non-FV group (difference, 2.2%; 95% CI, -3.2% to 7.4%). Other similarities between the FV vs non-FV groups included failure of first-pass margin (68/227 [30.0%]) vs 65/216 [30.1%]), regional failure (39/227 [17.2%] vs 37/216 [17.1%]), disease-specific survival (23/227 [10.1%] vs 19/26 [8.8%]), and overall survival (41/227 [18.1%] vs 38/216 [17.6%]) were also similar between groups. No adverse events were judged to be related to the intervention. Conclusions and Relevance: In this randomized clinical trial, FV-guided surgery did not improve local control rates in the treatment of patients with in situ or T1 to T2 category oral cancer. Under a controlled environment, FV-guided surgery did not have an evident effect in reduction of local recurrence for localized OSCC. This result suggests that attention be directed to strategies other than improving definitions of nonapparent disease at clinical margins to identify the sources of local recurrence.

Clinical evaluation of an automated virtual surgical planning platform for mandibular reconstruction.

BACKGROUND: Virtual surgical planning (VSP), via commercial services or developed in-house, has been applied to facilitate head and neck reconstruction. We evaluate a custom, automated planning software. METHODS: Prospectively, VSP of 25 consecutive patients undergoing segmental mandibular reconstruction was performed. Postoperative CT was used to assess structural accuracy of VSP. Operative time, length of stay, and complication rate of the prospective cohort were compared with those of 25 consecutive retrospective historical cases. RESULTS: The deviations between the plan and execution in mandibular width, projection, and volumetric overlap were 2.32 ± 3.91, 2.39 ± 1.72, and 0.59 ± 0.51 mm respectively. Compared with historical data, there was a significant reduction in operative time and length of stay, and no significant difference in complication rates. CONCLUSION: This is the largest prospective series evaluating an in-house VSP workflow for mandibular reconstruction and the first clinical evaluation of an automated planning platform.

Tumor microRNA profile and prognostic value for lymph node metastasis in oral squamous cell carcinoma patients.

Neck lymph node metastasis (LN+) is one of the most significant prognostic factors affecting 1-in-2 patients diagnosed with oral squamous cell carcinoma (OSCC). The different LN outcomes between clinico-pathologically similar primary tumors suggest underlying molecular signatures that could be associated with the risk of nodal disease development. MicroRNAs (miRNAs)are short non-coding molecules that regulate the expression of their target genes to maintain the balance of cellular processes. A plethora of evidence has indicated that aberrantly expressed miRNAs are involved in cancers with either an antitumor or oncogenic role. In this study, we characterized miRNA expression among OSCC fresh-frozen tumors with known outcomes of nodal disease (82 LN+, 76 LN0). We identified 49 differentially expressed miRNAs in tumors of the LN+ group. Using penalized lasso Cox regression, we identified a group of 10 miRNAs of which expression levels were highly associated with nodal-disease free survival. We further reported a 4-miRNA panel (miR-21-5p, miR-107, miR-1247-3p, and miR-181b-3p) with high accuracy in discriminating LN status, suggesting their potential application as prognostic biomarkers for nodal disease.

Predicting the Number of Fibular Segments to Reconstruct Mandibular Defects.

OBJECTIVES: Several classification schemes have been proposed to categorize mandibular defects following surgical resection; however, there is a paucity of data to guide an optimal reconstruction. This study examines the feasibility of using a geometric algorithm to simplify and determine the optimal reconstruction for a given mandibular defect. This algorithm is then applied to three different mandible defect classification schemes to correlate the defect type and number of bony segments required for reconstruction. METHODS: Computed tomography (CT) scans of 48 mandibles were decomposed into curvilinear representations and analyzed using the Ramer-Douglas-Peucker algorithm. In total, 720 mandibular defects were created and subsequently analyzed utilizing three commonly referenced classification systems. For each defect, the number of bony segments required to reconstruct each defect was computed. RESULTS: A wide variance in the number of segments needed for optimal reconstruction was observed across existing classifications. A six-segment total mandible reconstruction best reconstituted mandibular form in all 48 mandibles. CONCLUSION: Defect classification schemes are not adaptable to predicting the number of fibula segments required for a given defect. Additionally, cephalometric templates may not be applicable in all clinical settings. The Ramer-Douglas-Peucker algorithm is well suited for providing case-specific predictions of reconstruction plans in a reproducible manner. LEVEL OF EVIDENCE: IV Laryngoscope, 130:E619-E624, 2020.
