The 'International Society for the Study of Vascular Anomalies' (ISSVA) is the most widely accepted classification in the literature and is mainly based on the radiologic and clinical presentation. The aim of this article is to review the clinical practice of diagnosis and treatment of vascular anomalies in the head and neck region in a university hospital, with special focus on the nomenclature. All patients with a vascular anomaly presenting to the department of oral and maxillofacial surgery were reviewed in a retrospective manner. Nomenclature, diagnostic process, lesion characteristics, treatment and outcome were examined. The lesions were (re)classified according to the ISSVA classification. A total of 185 patients were identified, of which 12.4% (n = 23) had a congenital anomaly. After reclassification, the most common lesions were venous malformations (n = 47, 25.4%), followed by lobular capillary hemangiomas (n = 17, 9.2%). A group of 39 anomalies could not be further specified. One hundred and one patients (54,6%) received treatment, of which 93 were treated surgically (92,1% of treated patients). Endovascular treatment was considered in 41 patients but applied in only eight. This strict selection led to a low a complication rate. We provide an overview of the clinical practice in the management of vascular anomalies in a university hospital. The histology report is a source of miscommunication because clinicians use the ISSVA classification, while pathologists use the WHO classification. Every professional involved should be aware of the differences in classification and nomenclature.</p>","PeriodicalId":12994,"journal":{"name":"Head & Face Medicine","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10391867/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9935304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to a shortage of speech language pathologists (SLPs), automated detection tools could help improve access to care in underserved areas. The study compares the characteristics and accuracy of different types of machine learning algorithms. Methods: On August 18, 2021, searches were conducted across 8 databases: PubMed, SCOPUS, Cochrane, IEEE, ACM, L&LB, PsychInfo, and CINAHL. Search terms used were: (Artificial Intelligence OR Machine Learning OR Neural networks AND Cleft lip OR Cleft palate OR Hypernasality OR Velopharyngeal Insufficiency). To be included, papers needed to describe ML algorithms for CP speech detection and report concordance to human professional speech clinicians. Results: Database searches yielded 135 unique articles. Five articles met full inclusion criteria and 3 additional articles were identified by hand searching references of articles that passed initial screening. These algorithms were categorized as either Feature Dependent non-Deep learning (n = 5) or Feature Dependent deep learning (n = 2) algorithms or Feature Independent deep learning (n = 3) algorithms. Their pooled average concordance were 0.85, 0.93, and 0.91 respectively. Their average training database sizes were 3587, 3921, and 6306 speech samples respectively. Conclusion: Machine learning algorithms have been shown to be an effective tool for the evaluation of hypernasal speech. This systematic review has shown that ML algorithms are able to detect hypernasality with high concordance, consistent with professional speech language clinicians in a rapid, and autonomous manner. ML algorithms can extend the reach of speech language pathologists and complement their gold standard, this long-term outcome monitoring has great potential to improve treatment outcomes.","PeriodicalId":12994,"journal":{"name":"Head & Face Medicine","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88954961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No studies have reported a relationship between dental appliances in the setting of cleft palate management and oral cancer. This study characterizes the correlation between dental appliances and oral cancer and includes a case report of a patient with a history of cleft palate repair who later developed oral squamous cell carcinoma (OSCC). Methods: We performed a systematic review for studies from 1980 to 2022 of patients who had dental prostheses and who were subsequently diagnosed with OSCC. Variables included the percentage of OSCC cases wearing dental appliances, intraoral cancer location, and noted associations between reported risk factors and OSCC. Results: Of the 6323 patients from the 31 articles analyzed, the most common specified locations for the neoplastic lesion were at the gingiva and lateral border of the tongue. Seventeen studies found an association between OSCC and denture use (54.8%), while 9 studies (29.0%) specifically found a positive association between oral sores and OSCC. Our case patient had complete dental extraction at the age of 12 with subsequent life-long dentures. At age 69, he presented with invasive OSCC. Conclusions: Chronic irritation from ill-fitted dental appliances are associated with oral sores and cancer. This study reports a cleft palate repair patient with lifelong use of dentures who presented with OSCC despite having no known risk factors for oral cancer.","PeriodicalId":12994,"journal":{"name":"Head & Face Medicine","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78427445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: This preliminary 5-question cross-sectional study was conducted via a “quick poll” distributed by the National Dental Practice-Based Research Network (PBRN). Results: The final sample size was 280 general dentists and dental specialists. The majority of respondents agreed that orthognathic surgery could correct malocclusions affecting a patient’s speech, function, and long-term dental health. However, few respondents agreed that orthognathic surgery is an evidence-based treatment for obstructive sleep apnea or positively affects upper airway size.

Taub","doi":"10.1177/27325016231186304","DOIUrl":"https://doi.org/10.1177/27325016231186304","url":null,"abstract":"Introduction: Cannabis is the third most used recreational substance in the United States. Each year, more and more states pass legislation to legalize it for both medical and recreation use. As the prevalence of cannabis use increases, it is important to study the implications for patient care, not simply the potential interactions with wound healing, and perioperative analgesia. Facial fractures are among the most common traumatic presentations for the plastic surgeon. As such, the present study aims to characterize the operative facial fracture patterns in cannabis users. Methods: The IBM MarketScan Research Databases were queried from the years 2017 to 2021. Cohorts were identified in the inpatient dataset using International Classification for Disease, 10th Revision Procedure Coding System (ICD-10-PCS) codes for facial fracture repair procedures. The cannabis cohort was separated based on presence of ICD-10 codes pertaining to cannabis use diagnoses. The cohorts were propensity-score matched using an approximate 4:1 matching ratio. Baseline cohort demographics were reported and compared including age, gender, geographic region, employment status, insurance plan type, and fracture repair type. Multivariate regression analysis was used to determine the relationship between cannabis use and fracture repair patterns. Results: There were 104 patients in the cannabis cohort and 480 in the control cohort after propensity score matching. The cannabis group had a higher proportion of male patients (80.8%vs 69.0%, P = .016) and a lower proportion of the age range from 18 to 34 years (4.8%vs 15.8%, P = .035). Employment types were different between the 2 cohorts, with more patients in the control cohort working full time (82.3%vs 69.2%, P = .045). Cannabis users had significantly less maxillary fracture repairs (1.9%vs 19.4%, P < .001). Cannabis users also had significantly more frontal fracture repairs (1.9%vs 0.2%, P = .027) and mandibular fracture repairs (76.9%vs 63.8%, P = .010). Multivariate regression revealed that cannabis users have 1.8 times greater odds of undergoing mandibular fracture repair (P = .020) and significantly lower odds of undergoing maxillary (OR 0.07, P = .001). Conclusion: There are significant differences in the fracture patterns for cannabis users undergoing operative management and those who do not use cannabis. While mandibular fractures were the most common fracture repair type overall, cannabis users had significantly higher odds of undergoing mandibular fracture repair. This may indicate that cannabis users are more likely to sustain injuries that require operative intervention. Further study is needed to identify the relative incidences of facial fractures among cannabis users and its implications on operative considerations.","PeriodicalId":12994,"journal":{"name":"Head & Face Medicine","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81478371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study sought to conduct a comprehensive analysis of mandibular fracture malpractice cases. Specifically, the aim was to focus on the reasons a suit is brought, the outcomes, and the compensatory damages of litigation. The information is valuable to physicians as it may serve to minimize the risk of malpractice suits. Methods: The Westlaw and Lexis Nexis databases were searched for jury verdicts and settlements related to mandibular fracture malpractice lawsuits. Cases that did not meet the inclusion criteria, duplicate cases, and those for which enough information was not available were excluded. The data included reasons, outcomes, and monetary outcomes of litigations, as well as defendant specialty, location, year, and plaintiff demographics. Results: A total of 55 included cases spanned between 1970 and 2019. Of these, the most common reason a suit was brought included the defendant’s failure to make the diagnosis, which was noted in 27%. In 71% of the cases, the defendant was a surgeon; with 25% of these cases involving a plastic surgeon. Cases were resolved in favor of the defendant 51% of the time. Regarding outcome, 53% had a monetary outcome of $0. Conclusions: Although a slight majority of cases (51%) resulted in an outcome favoring the defendant, significant monetary consequences against the defendant were possible in cases when the plaintiff prevailed. Since failure to diagnose was the most common reason for a plaintiff to pursue litigation, physicians should thoroughly evaluate patients with suspected mandibular fractures to avoid litigation.","PeriodicalId":12994,"journal":{"name":"Head & Face Medicine","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73924636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
