The management of epistaxis is reviewed from ancient times onwards. Many curious methods have been employed and indeed epistaxis has been encouraged at times. Although current management is based on sound principles folklore remedies still predominate amongst some of our patients. The basis of contemporary treatments was known and practised by our ancient forebears.

The case notes of 185 patients who had bismuth-iodoform-paraffin paste (BIPP) impregnated ribbon gauze used for packing following ear surgery were analysed retrospectively. The incidence of hypersensitive allergic reactions to BIPP was 5.9 per cent and a five-fold increase risk of developing allergic reactions was found in those with previous exposure to BIPP. Where temporalis fascia was used to repair tympanic membrane defects, the incidence of tympanic membrane graft perforations was higher when allergic reactions to BIPP developed post-operatively, compared to non-allergic cases.

During setting and hardening, the hybrid bone substitute ionomeric cement (lonocem®) achieves a stable and durable bond with the apatite of the adjacent bone without interpository soft tissue. Fluid contact during setting results in the release of aluminium ions which may reach critical levels as high as 3000 μg/l. On epidural application it is, therefore, essential to prevent cement constituents from gaining access to the intradural space. After the cement has hardened, the presence of aluminium is demonstrable in the adjacent bone to a maximum depth of 20 μm (EDX microanalysis). In rabbits, epiduralplacement of freshly mixed cement causes slight thickening of the dura. There is reason to believe that human dura, with a thickness 10 times greater, is impermeableto components of the cement. After epidural application of the freshly mixed cement in the frontobasal and laterobasal regions and at the skull cap and petrous apex, 76 patients in all have been followed for up to 6.5 years. During this period no complications have arisen and functional (and cosmetic) results are promising. The availability of preformed implants (lonoroc®, lonocast®) permitted the peridural placement of minimal quantities of freshly mixed cement. These implants were fixed to localized sites on the adjacent calvarial bone by use of lonocem®. Notwithstanding the stringent manufacturer guidelines, there have been reports in the literature that during the vulnerable stage of setting neurotoxic aluminium ions were released into the dural space with a fatal outcome intwo cases. In view of potential intradural complications, such as may occur in case of dural leaks, it was considered that further application of the material adjacent to the dura was no longer warranted. The production of lonocem® was discontinued in May 1995.

An increasing number of surgical procedures are being performed on a day-case basis. In the UK otolaryngologists have been reluctant to introduce same day discharge in microlaryngeal surgery (MLS). The reason for this is the perceived risk to the airway from bleeding and oedema after MLS. The aim of this study was to investigate the feasibility of establishing a same day discharge service for MLS patients. One hundred consecutive patients under the care of one consultant otolaryngologist were recruited. A clinical street-fit assessment and objective measures of peak expiratory flow rate (PEFR) and oxygen saturation (SaO2) were recorded pre- and post-operatively. Results indicate that the PEFR and SaO2 did not change significantly during the course of the study. The street-fit criteria for discharge were satisfied in 80 per cent of patients following surgery. By combining the ASA score (American Society of Anaesthesiologists) with street-fitness 63 per cent of our patients were eligible for same day discharge.

Surgery is the first therapeutic option in extensive oropharyngeal carcinomas. An operation to treat these tumours is described, based on the hemiglossopelvectomy without mandibulectomy technique. Tumours located in the oropharynx are resected downwards by a modified pull-through approach, performing the resection of the oropharyngeal tumour in monoblock with the ipsilateral neck dissection, avoiding any action upon the mandible. The operation has been performed in 14 consecutive patients. By avoiding either mandibulotomy or mandibulectomy, morbidity and post-operative recovery are improved.

The usefulness of computed tomography (CT) in the diagnosis of fish bone impaction in the oesophagus was evaluated. Thirty-two patients were examined by plain X-ray followed by direct oesophagoscopy for suspected fish bone impaction. Among 25 cases in which fish bones were actually removed, foreign bodies were not clearly demonstrated by plain X-ray in 14 cases (56 per cent). Eleven cases underwent CT prior to the oesophagoscopic examination. Fish bones were clearly demonstrated by CT in all patients. CT also clearly visualized secondarily-induced inflammatory changes in the neighbouring structures. In order to confirm this result, we made a simulation model of oesophageal fish bone impaction, using fish bones of three different species surrounded by a water bag. In comparison with plain X-ray, CT depicted a superior image of fine fish bones and provides extremely useful information for the management of impacted fish bones in the oesophagus.

A case of bilateral progressive stenosis of both external auditory canals with resultant conductive hearing loss is presented. The stenosis revealed multifocal erosive and synechiant lichen planus. To our knowledge, this is the first reported case of lichen planus involvement of the external ear.

A case of mucormycosis involving the nose and paranasalsinuses in a 55-year-old man with recently diagnosed acute promyelocytic leukaemia is reported. It was successfully treated with a combination of aggressive surgical debridement and systemic amphotericin B. In addition, local nebulized amphotericin B was used as an adjunct totherapy. We believe this is only the second documented use of nebulized amphotericin in the management of sinonasal mucormycosis. The needfor a high index of suspicion and early aggressive management is emphasized.

Necrotizing fasciitis is a rare condition which usuallyaffects the trunk, perineum and limbs. Head and neck involvement is very uncommon and in most cases it is secondary to orbital or dental infection. We report a case of craniofacial necrotizing fasciitis (CNF) secondary to a maxillary sinusitis. The patient was treated intensively with antibiotics, surgical procedures and life-support measures.Despite all efforts, the patient died one week after admission. This case highlights early diagnosis and aggressive management as decisivefactors for the outcome of the patient.

Granular cell tumour (GCT) is a benign tumour with abundant eosinophilic cytoplasm filled with granules of varying sizes. These granules are the defining characteristic of the GCT and are believed to represent lysosomes in varying stages of fragmentation. The commonly used term granular cell myoblastoma, found in the older literature, is a misnomer because the tumour is clearly not of muscle origin. Among the major theories of origin, some support the tumour's derivation from neuronal tissue, histiocytes, fibroblast or Schwann cells. In the larynx, pseudoepitheliomatous hyperplasia may predispose to confuse the GCT with squamous cell carcinoma.

The most common region of GCT is in the head and neck, accounting for approximately 30 to 50 per cent of all lesions. The larynx is relatively an uncommon location for these tumours, accounting for approximately three to 10 per cent of the reported cases.

Affected patients typically present with persistent hoarseness, stridor, haemoptysis, dysphagia, and otalgia, but the tumour may be asymptomatic and be discovered only incidentally during a routine examination.

Complete excision with an attempt to maintain normal stuctures generally results in cure.

We present the case of a patient with typical features of a GCT of the larynx. The gross appearance, histopathology and brief discussion of the current literature are also presented.

Hoarseness of voice due to paralysis of the left recurrent laryngeal nerve caused by a dilated left atrium in mitral stenosis as discussed by Ortner, is a subject of controversy. Different authors have cited different mechanisms as explanation. A variety of cardiac problems such as primary pulmonary hypertension, ischaemic heart disease, various congenital heart disorders can all lead to paralysis of the left recurrent laryngeal nerve. Most authors believe that pressure in the pulmonary artery causes the nerve compression. In Papua New Guinea cor pulmonale and rheumatic heart disease are the commonest cardiac disorders seen. Ortner's syndrome is a rarity and has never been reported from here before. Here three different case reports are presented with mitral stenosis, primary pulmonary hypertension and combined mitral stenosis and regurgitation and the pathogenesis of hoarseness is discussed.

Hunter's syndrome is due to recessively inherited mucopolysaccharide storage diseases. The anaesthetic complications in this syndrome are related to the organs involved in the disease, but pertain especially to upper airway obstruction problems. We report a patient with Hunter's syndrome who, while under general anaesthesia for a simple procedure (the introduction of bilateral grommets), suffered a fatal outcome.

We report an unusual case of internal jugular vein thrombosis in a 57-year-old female, with the recently discovered factor V Leiden (FVR506Q) mutation. The molecular basis of this mutation is described, and the importance of screening for hereditary venous thrombotic states is emphasized.

A 20-year-old male presented with a small stab wound to the neck and with haemodynamic signs of significant haemorrhage, but no signs of local bleeding. On exploration, an intact vagus nerve and internal jugular vein were found, but the common carotid artery was not immediately apparent. Careful dissection confirmed a completely transected common carotid artery with the two ends contracted and retracted. A primary repair was performed and post-operatively the patient recovered completely and had no neurological deficit.

Oncogenic osteomalacia is an uncommon syndrome characterized by mineral metabolism abnormalities that disappear after the resection of an associated tumour. Head and neck is the second most frequent location of these tumours. We describe a case with an ethmoido-frontal phosphaturic mesenchymal tumour and review oncogenic osteomalacia-associated tumours. Among 21 cases found, 57 per cent affected the sinonasal area and 20 per cent the mandible. The diagnosis of the tumour lasted a mean of 4.7 years from the onset of osteomalacia, and most of them showed a significant vascular component. An aggressive surgical approach is recommended.

Ectopic thyroid is an uncommon embryological aberrationcharacterized by the presence of thyroid tissue at a site other than in its usual pretracheal region. Usually it occurs along the path of descent of the developing thyroid primodium from the foramen caecum, commonest being lingual followed by sublingual and in the anterior midline of neck at, or below, the level of the hyoid bone. It is unusual for lingual thyroid to present simultaneously with another ectopic thyroid; reported here are two such cases.

Recurrent epistaxes after head injury may rarely be dueto a traumatic intracavernous carotid artery pseudoaneurysm. The headinjury is usually associated with fracture of the skull base and the epistaxes are severe with the first episode generally occurring one to three months after the initial trauma. We present a case which illustrates the role of high resolution computed tomography (CT) scanningand also magnetic resonance angiography (MRA) in achieving the diagnosis.

Verrucous carcinoma is a distinct variant of well differentiated squamous cell carcinoma. Its occurrence in the maxillary antrum is rare. Only three cases have previously been documented. We present a case report of verrucous carcinoma in the maxillary antrum and a review of the literature.
