The international expert consensus on management of external auditory canal carcinoma.

Purpose: The objective of this consensus is to provide otolaryngologists with appropriate strategies in the management of external auditory canal (EAC) carcinoma.

Methods: In the absence of randomized controlled trials, the consensus is based on expert opinions utilizing the Rand/UCLA appropriateness method [Fitch and Aguilar in The RAND/UCLA appropriateness method user's manual, RAND Corporation, Santa Monica, CA, 2001], drawing from existing literature and clinical experience.

Results: The management recommendations are structured around 12 key areas, including: definition and pathology, pathogenesis, clinical manifestations, work-up, tumor staging system, surgical management of primary tumor, surgical management of the parotid gland and the temporomandibular joint, lymph node metastasis, radiotherapy, chemotherapy, reconstruction, and follow-up.

Otolaryngology contribution to the care of patients following non-fatal strangulation in the settings of alleged sexual assault.

Background: Non-fatal strangulation as a consequence of a sexual assault attack or domestic violence represents serious bodily harm. Otolaryngologists have an important role in documenting physical findings and managing airway symptoms. This study aimed to describe our otolaryngology department's experience managing patients referred from the sexual assault referral centre who suffered non-fatal strangulation.

Management of a recurrent right juvenile nasopharyngeal angiofibroma using direct tumorous puncture embolisation and a subtemporal-preauricular infratemporal fossa surgical approach.

A juvenile nasopharyngeal angiofibroma (JNA) is a benign vascular tumour that arises from the pterygopalatine fossa. It is seen near exclusively in young males though female cases have been reported. Symptoms are due to their high vascularity and mass effect.

A case report of anaplastic thyroid cancer and papillary thyroid cancer lymph node metastasis: an unusual presentation as an invasive hypopharyngeal mass.

Anaplastic thyroid carcinoma is a rare undifferentiated tumour of the thyroid follicular epithelium. It almost always develops from a pre-existing well-differentiated thyroid cancer with a co-existent thyroid malignancy varying from 5 to 17% . The co-existence of papillary thyroid cancer (PTC) with anaplastic thyroid cancer is a rare occurrence in metastases outside the primary thyroid lesion.

Skull base chondroblastoma presenting as a deep lobe parotid tumour.

Chondroblastomas are rare, benign cartilage-producing primary bone tumours that account for 1% of all primary bone tumours. They are usually seen in young adult males and affect long tubulous bones such as the femur or humerus. Occurrences in non-tubular flat bones such as the craniofacial skeleton do occur but are seen in older adults.

Squamous Cell Carcinoma and Its Variants.

Squamous cell carcinoma (SCC) is one of the most common malignant neoplasms involving the anterior skull base, resulting from local invasion from an adjacent anatomical region. The primary sites of origin are most frequently the nasal cavity and paranasal sinuses, and less often the skin and orbit. Treatment strategies for these tumors have evolved, although management remains challenging due to the proximity to critical structures and their location at the intracranial-extracranial interface.

Recurrence of a complex anterior skull base tumour managed with an uncommon surgical approach.

A well 74 -year-old woman presented to routine ophthalmology clinic instituted following treatment of a frontoethmoidal sarcoma initially excised in 1989 and diagnosed then as a sinus mucosal melanoma. At review in ophthalmology clinic, a reduction in right visual fields was noted. CT scan showed recurrence of a mass now involving the frontoethmoidal region, frontal sinus and abutting the cribiform plate.

Macrodissection prior to closed system RT-qPCR is not necessary for estrogen receptor and HER2 concordance with IHC/FISH in breast cancer.

An on-demand, closed RT-qPCR, the GeneXpert (GX) system, has the potential to provide biomarker information in low-resourced settings and elsewhere. We used this system with a research use only version of the Breast Cancer STRAT4 cartridge that measures the mRNA expression levels of ERBB2, ESR1, PGR, and MKi67. Here we evaluated the impact of non-macrodissected (non m-d) versus macrodissected (m-d) samples using STRAT4 on formalin-fixed, paraffin-embedded (FFPE) core needle biopsies.

Role of 18-Fludeoxyglucose positron emission tomography-computed tomography and subsequent panendoscopy in head and neck squamous cell carcinoma of unknown primary.

Objectives/hypothesis: Head and neck squamous cell carcinomas of unknown primary (HNSCCUP) accounts for up to 10% of presenting head and neck squamous cell carcinomas. Identification of the primary site allows for directed therapy. Where initial investigations have failed to locate the primary site, 18-fludeoxyglucose positron emission tomography-computed tomography (PET/CT) has emerged as a useful tool with improved sensitivity over positron emission tomography alone.

Management of the compromised airway and role of tracheotomy in anaplastic thyroid carcinoma.

Background: Anaplastic thyroid carcinoma (ATC) is an uncommon thyroid malignancy with a poor prognosis. American Thyroid Association (ATA) guidelines acknowledge the complexity of airway management in these patients. We studied our local experience with the aim of providing guidance in airway management in ATC.

A 26-gene hypoxia signature predicts benefit from hypoxia-modifying therapy in laryngeal cancer but not bladder cancer.

Purpose: Tumor hypoxia is associated with a poor prognosis, hypoxia modification improves outcome, and hypoxic status predicts benefit from treatment. Yet, there is no universal measure of clinical hypoxia. The aim of this study was to investigate whether a 26-gene hypoxia signature predicted benefit from hypoxia-modifying treatment in both cancer types.

Investigating the value of fine needle aspiration cytology in thyroid cancer.

Background: Current guidance recommends the use of fine needle aspiration cytology (FNAC) as an essential investigation in patients presenting with a thyroid lump. Current literature suggests that the sensitivity of FNAC in thyroid nodules ranges between 80-90%. However, only very few studies have looked specifically at the sensitivity of FNAC in solely thyroid cancer patients.

The Lester-Jones tube and scuba diving.

Insertion of a Lester-Jones tube remains the standard treatment for epiphora secondary to canalicular obstruction. We report on a patient requiring removal of his correctly working Lester-Jones tube to allow him to continue his hobby of scuba diving. This particular complication of the Lester-Jones tube has never previously been reported in the literature.

Removal of inhaled foreign bodies--middle of the night or the next morning?

Objective: Foreign body inhalation is a potentially life-threatening emergency and is the commonest cause of accidental death in children under one year old. There is varying opinion regarding the urgency for removal of inhaled foreign bodies; most centres in the United Kingdom will take the patient to theatre as soon as can be arranged, regardless of the time of day. At Great Ormond Street Hospital for children it has been standard practice to perform rigid bronchoscopy and removal of an inhaled foreign body on the next available daytime operating list, providing the patient is clinically stable, even if this incurs a delay until the following day.

A novel use of photo messaging in the assessment of nasal fractures.

We evaluated a new method of assessing patients referred to the otolaryngology department with nasal injury. Patients possessing a mobile phone with built-in camera took an image of their face and sent it to the department for assessment. A decision was then made as to whether the patient needed further consultation or treatment.

Spontaneous parapharyngeal haematoma caused by a leaking vertebral artery pseudoaneurysm.

We describe an unusual case of spontaneous parapharyngeal haematoma, in a patient with haemophilia. The cause was a leaking extracranial vertebral artery pseudoaneurysm eroding through the atlas at the level of the skull base. The leaking pseudoaneurysm was successfully controlled with embolisation of the vertebral artery.

Usefulness of CT scans in malignant external otitis: effective tool for the diagnosis, but of limited value in predicting outcome.

Computerized tomography (CT) scanning is a well recognised tool for the diagnosis of malignant external otitis. To investigate the degree of correlation between CT findings scan and the patients clinical status focusing on a subgroup of patients with cranial nerve palsies. Diagnosis of malignant external otitis was confirmed in 23 patients (average age 71 years, age range 39-87) based on criteria of severe pain, otitis externa refractory to conventional treatments and possibly diabetes mellitus and pseudomonas detection.

Cranial nerve involvement in malignant external otitis: implications for clinical outcome.

Background: Malignant external otitis is an uncommon, potentially lethal infection of the temporal bone primarily affecting elderly diabetic patients.

Objective: To determine whether cranial nerve involvement in malignant external otitis affects or predicts the clinical outcome in terms of morbidity and mortality.

Methods: Diagnosis of malignant external otitis was established in 23 patients (average age, 71 yr; range, 39-87) based on inclusion criteria of severe pain, otitis externa refractory to conventional treatments, diabetes mellitus, and Pseudomonas aeruginosa detection.
