It is important to evaluate the accuracy of CBCT-based implant size prediction. This study aims to correlate projected implant sizes from CBCT alveolar ridge measurements with the actual sizes of placed implants, to determine the accuracy of the prediction.Materials and methods: CBCTs taken for implant placement were included. The heights and widths of edentulous ridges were measured with Anatomage in vivo dental three-dimensional software, and actual implant size data were retrieved from treatment notes. Central incisor, canine, first premolar and first molar locations were analysed. One-way analysis of variance (ANOVA) was run to determine the average sizes for edentulous ridges and implants and Pearson correlation was conducted to determine the accuracy of CBCT-based implant size prediction.Results: Of 544 cases analysed, the average implant diameter was 4.17 mm (standard deviation [SD] =0.38) and the length was 10.05 mm (SD =1.17). Alveolar width and height were 3.74 mm and 4.31 mm larger than the implant diameters and lengths, respectively providing approximately 1.5-2 mm of extra space on either side of the implant in relation to adjacent anatomical structures. Implants placed at mandibular canine and first molar and maxillary first premolar demonstrated significant correlations with the sizes of the edentulous ridges (P < 0.05).Discussion: CBCT-based alveolar ridge measurements have been demonstrated as reliable parameters to predict implant sizes. However, its accuracy may be limited by the factors such as edentulous ridge morphology and proximity to vital anatomic landmarks.","PeriodicalId":7972,"journal":{"name":"Annals of Maxillofacial Surgery","volume":"14 2","pages":"187-191"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11828063/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can also occur in the craniofacial region such as mandibular condyle and coronoid region. We describe the clinical presentation, diagnostic process, surgical management and post-operative outcomes in a 34-year-old male patient. Only few cases are reported in literature till now and often are mistaken as bony exostosis.Patient concerns: The patient sought medical attention due to the cosmetic concerns.Diagnosis: Through clinical palpation and radiological interpretation. Provisional diagnosis of bony exostosis was made, which was later confirmed as osteochondroma on histopathological examination.Treatment: Surgical removal of the bony growth was performed.Outcomes: Follow-up was uneventful with no evidence of recurrence.Take-away lessons: The report aims to raise awareness about this manifestation and to encourage further research to better understand aetiology, management and outcomes of osteochondroma in unusual locations.","PeriodicalId":7972,"journal":{"name":"Annals of Maxillofacial Surgery","volume":"14 2","pages":"232-235"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11828045/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143432304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is the most common site of primary intraoral cancer. A fasciocutaneous free flap is the first reconstructive option after surgery.Materials and methods: The aim of this study was to investigate the functional outcomes in patients treated with hemiglossectomy. We evaluated the objective tests and subjective assessments of swallowing, speech and sleep at 30 days after the surgery (T0) and at least 6 months after the end of the treatment (T1). We have implemented a battery of validated tools that comprehensively evaluate functional outcomes after resection of oral cancer, including speech, swallowing and head-and-neck-specific quality of life: MD Anderson Dysphagia Inventory (MDADI), Performance Status Scale-Head and Neck (PSS-HN) and Lazarus Tongue Range of Motion (ROM) Scale. Patients underwent objective tests such as videonasal endoscopic evaluation and magnetic resonance imaging. All patients were subjectively assessed with the Epworth Sleepiness Scale and underwent nocturnal polygraphy.Results: We treated six patients with advanced squamous cell carcinoma of the tongue; three received radial forearm flap and three received anterolateral thigh flap. Our study found that ROM, flap volume and defect volume are the most important characteristics for better MDADI, PSS-HN, Epworth score and respiratory disturbance index (RDI) on polygraphy.Discussion: Reconstruction of tongue cancer defects is challenging as the surgeon must consider adequate control of the tumour while also optimising residual functional capacity. The volume of the flap and ROM would seem to be the most important characteristics for improving the functional outcome.","PeriodicalId":7972,"journal":{"name":"Annals of Maxillofacial Surgery","volume":"14 2","pages":"200-205"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11828057/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143432362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have previously reported on ethnic and age groups disproportionately affected by these injuries and the impact of the COVID-19 lockdowns. This study provides an analysis of the aetiologies contributing to maxillofacial fractures over a period of 11 years.Materials and methods: Patients who were referred with a maxillofacial fracture to the Wellington Regional Plastic, Maxillofacial and Burns Unit from January 1, 2013 to December 31, 2023, were identified from our maxillofacial fracture database. The aetiology of injury was classified as interpersonal violence (IPV), fall, sport, road traffic accident (RTA), other or unknown. The number caused by each aetiology was correlated with year of injury to produce a trend over time.Results: A total of 2651 cases were identified during the study period. IPV was the most common aetiology, followed by fall, sport, RTA, other and unknown. The total number of injuries per year did not change significantly, nor did the number of injuries caused by sport, other or unknown aetiology. The number of injuries from IPV decreased by 3.9% per year, fall increased by 4.4% per year and RTA increased by 7.2% per year.Discussion: IPV remains the leading cause of maxillofacial fractures, although this is decreasing. The number of maxillofacial fractures caused by RTA is increasing. There is a sustained increase of maxillofacial fracture caused by falls, which especially affect the elderly, warranting further study of possible causes and preventative strategies.","PeriodicalId":7972,"journal":{"name":"Annals of Maxillofacial Surgery","volume":"14 2","pages":"192-195"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11828073/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143432232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, two different routes of administration of dexamethasone 8 mg (intravenous [IV] vs. submucosally infiltrated) were used to evaluate the role of dexamethasone in reducing the post-operative inflammatory sequelae following lower third molar removal.Materials and methods: Sixty patients who had to undergo surgical removal of mandibular third molars were randomly divided into two groups, each group consisting of 30 patients. One group of patients was administered 8 mg dexamethasone submucosally five min before the surgery. Another group of patients received 8 mg dexamethasone intravenously five min before the surgery. Facial swelling and pain were measured on the 2nd, 4th and 7th post-operative days.Results: The results of this study revealed that both the routes were effective in controlling post-operative pain and swelling. IV route of dexamethasone showed higher efficacy compared to submucosal (SM) route of dexamethasone in reducing the post-operative inflammatory sequelae in the surgical removal of impacted lower third molar teeth.Discussion: It was seen that IV dexamethasone (8 mg) and submucosal dexamethasone (8 mg) had equivalent ratings in terms of reduction of swelling and pain. Although the results of this study showed both the routes are effective in controlling post-operative swelling and pain after third molar surgery, the study concluded that certain benefits of submucosal route make the sm route to be a valuable alternative to iv dexamethasone.","PeriodicalId":7972,"journal":{"name":"Annals of Maxillofacial Surgery","volume":"14 2","pages":"141-146"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11828056/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143432370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
