Introduction
ElaTION is a large multi-centre pragmatic randomised controlled trial, performed in 18 secondary/tertiary hospitals across England, comparing elastography ultrasound-guided fine needle aspiration cytology (EUS-FNAC) with ultrasound-guided FNAC (US-FNAC) alone in the diagnostic assessment of thyroid nodules. Secondary trial outcomes, re...
Background There is variable evidence and no randomized trials on the benefit of US elastography-guided fine-needle aspiration cytology (FNAC) over conventional US-guided FNAC alone for thyroid nodules. Purpose To compare the efficacy of US elastography-guided FNAC versus US-guided FNAC in reducing nondiagnostic rates for thyroid nodules. Materials...
Objectives
The clinical activity score (CAS) and European severity scale (ESS) are established clinical tools to assess thyroid eye disease (TED) but are limited in terms of subjectivity and their reliability in non-Caucasian individuals, and can underestimate significant disease in the posterior orbit. Preliminary data from pilot studies have show...
Background
Strain and shear wave elastography which is commonly used with concurrent real-time imaging known as real-time ultrasound shear/strain wave elastography is a new diagnostic technique that has been reported to be useful in the diagnosis of nodules in several organs. There is conflicting evidence regarding its benefit over ultrasound-guide...

With the widespread use of 18F‐fluorodeoxyglucose positron emission tomography (FDG PET/CT) in the investigation and staging of cancers, incidental discovery of FDG‐avid thyroid nodules is becoming increasingly common, with a reported incidence in the range 1‐4% of FDG PET/CT scans. The risk of malignancy in an incidentally discovered FDG avid thyr...
Although anterior skull base tumours are rare, with a wide range of pathologies that demonstrate a range of prognoses, due to their rarity, the literature to date often combines cases with different pathologies into the same case series, so as to evaluate treatment outcomes. Curative management is predominantly with surgery (craniofacial resection...
Recent advances in image-guided techniques allow endoscopic surgery to extend beyond the sinonasal cavity to the pterygopalatine fossa, orbit, anterior skull base and petrous apex. These techniques reduce complication rates compared with traditional open surgery (craniotomy or trans-facial) and require a multidisciplinary team review of imaging and...
• ● A functioning facial nerve is a critical structure that limits the margin of resection in parotid malignancies. There was no difference in disease-free survival with close or negative resection margins.
• ● Microscopic positive (R1) resection margins were associated with poorer disease free survival, but this was not statistically significant,...
Laryngeal trauma is a life‐threatening injury in contact sports. Due to its potentially devastating consequences, the prevention, diagnosis, and management of neck trauma both pitch side and at the hospital are essential for athletes.
The energy needed to drive airflow through the trachea normally constitutes a minor component of the work of breathing. However, with progressive tracheal compression, patient subjective symptoms can include severe breathing difficulties. Many patients suffer multiple respiratory co-morbidities and so it is important to assess compression effects w...
CT scan images of the larynx are formatted in an oblique axial plane at the level of the paralysed vocal cord.
