Diagnostic accuracy of magnetic resonance imaging in detecting depth of invasion of tongue cancers.

The recent eighth edition of the American Joint Committee on Cancer (AJCC) staging system has introduced depth of invasion (DOI) as one of its important components. DOI is also important for deciding neck management in superficial tongue cancers. Magnetic resonance imaging (MRI) is mainly used to assess DOI, and in this study we have evaluated the efficacy of MRI to detect it. This is a retrospective study consisting of 60 treatment-naïve tongue cancer patients operated on between July 2017 and June 2019. Patients underwent MR imaging on an Optima MR450W 1.5T unit, and MRI was reported by two experienced head and neck radiologists. Postoperative histological DOI was considered the gold standard. The correlation coefficient was derived for postoperative DOI and MRI-detected DOI. A subgroup analysis of superficial tongue cancer was also done. The mean MRI DOI was 13.7 mm and the mean histological DOI 12.45 mm. The shrinkage factor was 0.6 mm. Pearson's correlation coefficient was 0.80 (p=<0.001) for Radiologist 1 and 0.85 (p=<0.001) for Radiologist 2. The interobserver variation was low, with a correlation coefficient between the two radiologists of 0.965 (p=<0.001). For superficial tongue cancers there was moderate correlation for MRI and histologically-detected DOI with a kappa value of 0.681 (p=0.03). As per the ROC curve, the cut-off value for MRI DOI to predict nodal metastasis was 4.6 mm. MRI has high reliability to predict the DOI of tongue cancers. The interobserver variation was low. The diagnostic accuracy in cases of superficial tongue cancer was moderate.

Are patients satisfied with the head and neck skin cancer service? An evaluation of outpatient services with a review of published reports.

Scientific publications place much emphasis on postoperative outcomes such as recurrence, but little attention to patients' satisfaction. The purpose of this evaluation was to find out patients' reported outcomes after their initial consultation, treatment, and follow-up appointments for non-melanoma skin cancer of the head and neck. We used an adapted version of the European Organisation for Research and Treatment of Cancer (EORTC) validated questionnaire for patients' satisfaction to collect data prospectively from consenting patients between September and December 2015. A total of 179 questionnaires were completed (initial consultation n=51, treatment n=74, and follow up n=54). Patients were most satisfied with the appointments for treatment (Kruskal-Wallis p<0.001, mean (SD) score 4.86/5 (0.15)), and 87% regarding the service as excellent. Patients were least satisfied with services and organisation of care compared with nurses and doctors (Kruskal-Wallis p<0.001). There seemed to be most satisfaction after the appointment for treatment. A possible explanation could simply be the relief of having finally had their cancer removed. Patients are also likely to show greater satisfaction with the clinical team because of the personal nature of the interaction that they experience during this aspect of their care.

Predictive factors of hospital stay in patients with odontogenic maxillofacial infections: the role of C-reactive protein.

To investigate whether clinical or laboratory variables on admission of patients with odontogenic infections are associated with a severe clinical course and a prolonged hospital stay, we hypothesised that specific factors such as the serum concentration of C-reactive protein (CRP) may act as predictors of the duration of stay. We designed a prospective patient-oriented study that included all those treated for maxillofacial infections of odontogenic origin in the Oral and Maxillofacial Surgery Department of Northampton General Hospital between November 2013 and December 2014. A total of 71 were enrolled. We found that the concentration of CRP was a significant predictor of hospital stay (p=0.01). Its measurement on admission can predict the likely duration of stay of these patients and enable beds to be managed more efficiently.

Effect of peripheral vascular disease on the blood supply of the anterolateral thigh free flap: a radiographic study.

BACKGROUND: The anterolateral thigh flap has gained popularity over the last few decades for the reconstruction of various surgical defects. The anatomy of the main perforating vessel of the anterolateral flap, the descending branch of the lateral circumflex femoral artery (dbLCFA), has been well described in the literature, however only one study has investigated its patency in patients with significant comorbidities. The aim of this study is to assess the degree of vascular stenosis of the dbLCFA in patients with multiple comorbidities. PATIENTS AND METHODS: A total of 128 sets of angiographic data were collected from 93 patients retrospectively over a 12-month period. The percentage stenosis of superficial femoral artery (SFA), LCFA, and dbLCFA was measured and converted into an established scoring system. RESULTS: The rate of dbLCFA stenosis was 12.5%. Interestingly, 24.0% of patients without peripheral vascular disease (PVD) showed some degree of stenotic changes in the dbLCFA, whereas only 10.7% of those with PVD had some degree of stenosis. There was no correlation between dbLCFA stenosis and patient comorbidity. The SFA was significantly affected by smoking, hypercholesterolemia (p < 0.05), and diabetes mellitus (p < 0.01) CONCLUSIONS: This study shows that the dbLCFA is not affected by patient comorbidity including PVD when compared with medically fit controls. Even in individuals with severe disease of the superficial vascular system; there is often sparing of the deep system. Surgical reconstruction using the anterolateral thigh flap is a safe procedure for patients even with multiple comorbidities including significant PVD and no additional preoperative investigations are required.

Patients' expectations and online presence of Oral and Maxillofacial Surgery in the United Kingdom.

In patient-centred medical practice, consideration of the patients' expectations is vital to the planning and delivery of service. Modern medicine must use the continuing advances in information technology to disseminate knowledge and raise awareness among patients and the public. People increasingly use the Internet to search for information on health, and the online presence of an organisation or a profession is known to bring a wide range of benefits. We aimed to find out what patients expect from the website of an Oral and Maxillofacial Surgery (OMFS) unit and to assess the online presence of OMFS units in the United Kingdom. Results from 100 self-administered questionnaires showed that there were 18 common domains that patients would like to see on OMFS websites. When ranked according to the number of times they were mentioned, a map of the department was mentioned most and the complaints policy least. Of the 156 OMFS units in the UK, only 51% have websites and of these, 80% are in London. There were none in Wales and Northern Ireland. Only half of the websites contained information that related to patients' expectations. Strategies to improve the content of websites for OMFS units and to improve their online presence are urgently needed.

A randomized controlled trial on cross-infection control in maxillofacial trauma surgery: a comparison of intermaxillary fixation techniques.

Glove perforations and percutaneous injuries occur commonly during the treatment of facial fractures and reveal the need for safer techniques, especially in intermaxillary fixation. The Rapid IMF device does not use any wires and may provide better cross-infection control than wiring methods. The aim of this study was to test the hypothesis that Rapid IMF is associated with fewer glove perforations/ percutaneous injuries than traditional wiring techniques. The authors carried out a randomized controlled trial which included 120 patients with fractures of the mandible requiring open reduction and fixation. The participants were allocated either to the study group and treated with intraoperative Rapid IMF or to the control group and managed with intraoperative eyelet wire ties. Analysis of the results showed that the Rapid IMF group had significantly fewer glove perforations than the traditional method (0.67 per operation compared with 1.5), (P<0.0001). The incidence of skin-penetrating injuries was the same in both groups (rate 0.02/ procedure). The application of Rapid IMF was significantly faster than wiring (P<0.0001). Minor intraoperative complications were noted in both groups, but more in the Rapid IMF group. Most concerned loosening or fracture of the anchorage ties but the surgical outcome was not affected. Rapid IMF is a safer alternative to wiring methods with significant reduction in glove perforation rates and is quicker to apply than conventional wiring techniques.

'The interpreter' in the maxillofacial outpatient clinic.

The role of an interpreter is crucial in an ethnically diverse city such as Leicester. Four hundred and seventy-three patients attending the outpatient department were studied. The majority could speak English to some degree. Thirty-one (7%) patients required an interpreter. This was most frequently a family member (70%) or multilingual clinician (27%). The latter are a valuable resource in the health service.

Partial avulsion of the inferior rectus: an unusual cause of diplopia after blunt orbital trauma.

A 14-year-old boy had a severe blow to the right orbit, which caused a blow-out fracture of the orbital floor and damage to the inferior rectus with resultant diplopia. After two operations his vision is still not perfect.

Infection of surgical wounds in the maxillofacial region and free flap donor sites with methicillin-resistant Staphylococcus aureus.

We studied the acquisition of methicillin-resistant Staphylococcus aureus (MRSA) in two groups of patients who had free flap reconstructions of defects after excision of lesions in the head and neck. The first group (n=31) was given a 5-day perioperative course of antibiotic prophylaxis (long-term) and the second (n=33) a 24-h course (short-term). MRSA was the main infecting organism. Seventeen of the 64 patients (27%) developed an infection with MRSA, including seven at donor sites of free flaps. All infections were acquired after operation, and delayed healing or discharge in five patients with MRSA and four with infections with other organisms. The median length of hospital admission was greater for patients that acquired MRSA (p=0.005). There were significantly fewer patients with wounds infected by MRSA in the short-term group (4/33 compared with 13/31, p=0.01). We recommend the short-term use of an antibiotic for surgical prophylaxis and the application of cross-infection control measures on the ward.

Use of an external fixator to stabilise the proximal mandibular segments during reconstruction.

The main aims of mandibular reconstruction are to reproduce the three dimensional position of the patients' mandible with the condyles in the glenoid fossae. We describe a simple technique using an external fixator to stabilise the proximal mandibular segments during resection to aid reconstruction.

Synovial sarcoma of the hard palate.

Synovial sarcoma is a rare soft tissue tumour of uncertain histogenesis and intraorally they occur mainly in young adults. We present a case of synovial sarcoma of the hard palate in a 68-year-old woman. To our knowledge, there is no previously reported instance of this tumour at this site.

Serum sialic acid, a reputed cardiovascular risk factor, is related to serum leptin concentrations in Fijians.

BACKGROUND: Serum sialic acid (TSA) has been shown to be a cardiovascular risk factor and an acute phase reactant, with elevated concentrations associated with increased cardiovascular mortality and to precede the onset of type 2 diabetes. AIM: The purpose of this present study was to test the hypothesis that serum TSA may be related to serum leptin concentrations in healthy individuals. METHODS: Thirty Fijian individuals were studied (8 males and 22 females). They were urban Melanesians living in Raiwaga, a suburb of Suva in Fiji. RESULTS: Serum TSA significantly correlated with subject body mass index (BMI, rho 0.39, P<0.05) and serum leptin concentration (rho 0.44, P<0.05). In stepwise multiple regression analysis serum TSA independently correlated with subject waist/hip ratio (r(2)=0.167, P<0.02) and diastolic blood pressure (r(2)=0.300, P<0.01) but not with age, BMI, serum insulin-like growth factor binding protein (IGFBP-1), fasting plasma glucose or systolic or diastolic blood pressure. CONCLUSIONS: Serum TSA is related to markers of obesity and adipose tissue metabolism which may help to explain why it is a reputed cardiovascular risk factor and why elevated serum TSA concentrations precede the development of type 2 diabetes mellitus.

Serum sialic acid, a possible cardiovascular risk factor is not increased in Fijian Melanesians with impaired glucose tolerance or impaired fasting glucose.

BACKGROUND: Serum total sialic acid (TSA) has been shown to be a strong cardiovascular risk factor with increased concentrations being associated with increased mortality. Serum TSA is also elevated in patients with type 2 diabetes including those with micro- and macrovascular complications. We wished, therefore, to test the hypothesis that serum TSA may be abnormal in individuals with impaired glucose tolerance (IGT) and impaired fasting glucose (IFG), in Fijian Melanesians. METHOD: Twenty-one subjects with IGT (17 women and four men) were recruited along with 20 subjects with IFG (14 women and six men) and 22 normal subjects (12 women and 10 men). Serum TSA was 2.18 +/- 0.027 mmol//L, 2.19 +/- 0.033 mmol/L and 2.24 +/- 0-042 mmol/L in the three groups, respectively, which was not statistically different. Both systolic and diastolic blood pressure were, however, higher in the IGT group compared with the IFG and normal groups (P<0.04). CONCLUSION: Serum TSA is not elevated in Fijian Melanesians with IGT and IFG although it is reported to be elevated in type 2 diabetes mellitus in other populations. Further research is needed to establish why serum TSA is a potent independent cardiovascular risk factor and is elevated in type 2 diabetes mellitus in some populations.

Atypical ameloblastoma: report of 3 cases and a review of the literature.

This paper presents 3 atypical ameloblastomas which had a fatal outcome. One had histological features indicative of malignancy but without metastasis, another developed pulmonary metastasis and the third died of extensive infiltration of the skull base. The features of malignant ameloblastoma are discussed and reported cases of malignant ameloblastoma between 1966 and 1993 are reviewed.

So you think they know what we do? The public and professional perception of oral and maxillofacial surgery.

In order to assess knowledge about the specialty of oral and maxillofacial surgery amongst the public and both general medical and dental practitioners, a questionnaire was devised. 200 members of the public were selected at random in one district, 50 local dentists and general medical practitioners were selected and all were telephoned to obtain their answers. The results reveal that the majority of the public need more information about the benefits that our specialty can offer them or their patients. Medical practitioners are better informed but lack information about where our major activity lies. Even dental practitioners have not been kept up to date with recent developments in our specialty and may refer to other specialties, patients with conditions which members of our Association routinely manage. If patients are to receive the best treatment available, it is essential that we educate the public (and especially the Purchasers) about our clinical interests and activities.
