Desmoid tumours are histologically benign fibrous neoplasms arising from the musculoaponeurotic structures throughout the body. They are characterized as infiltrative, usually well-differentiated firm overgrowths of fibrous tissue and are locally aggressive. An aggressive clinical behaviour with tendency for recurrence makes the treatment of these relatively rare fibrous tumours difficult. Local recurrence rates are reported as high as 70 per cent of cases, the recurrence of desmoid fibromatosis in the head and neck is difficult to ascertain because of the different classification schemes used by different authors. A review of cases of desmoid tumours of the head and neck presented in the last 10 years is reported in this paper. Complete surgical excision of desmoid tumours is considered to be the only effective method of cure by most authorities.

Sensorineural hearing loss is a common symptom in patients with myoclonic epilepsy associated with ragged-red fibres (MERRF), one of the mitochondrial encephalomyopathies, although the lesion causing hearing loss in such cases remains unknown. Here we describe the audiological features in three MERRF patients, all of whom exhibited a point mutation in their mitochondrial DNA at nucleotide 8344. Pure-tone threshold audiometry revealed bilateral, sloping-type, sensorineural hearing loss in all three patients. Distortion product otoacoustic emissions, electrocochleography, and auditory brainstem responses were variable, even differing between the right and left ears of the same patient. Taken together, our findings suggest that the primary lesion underlying hearing loss in MERRF patients is in the cochlea, although a retrocochlear lesion may be involved in some patients.

This paper attempts to define and categorize the vertigo associated with migraine. A retrospective chart review of 344 cases of vertigo identified 19 cases with headaches characteristic of migraine as per strictly defined criteria (International Headache Society, 1988).Four distinct types of vertiginous syndromes were noted. The commonest syndrome (Group I) manifested transient episodes of imbalance with additional momentary subjective rotary vertigo worsened by movement. The attacks lasted a few hours and evaluation in the inter-episode interval demonstrated no vestibular deficit. Group II manifested transient objective rotatory vertigo of from 10 minutes to a few hours but no demonstrable permanent vestibular deficit. Group III displayed symptoms and signs characteristic of benign paroxysmal positional vertigo (BPPV) and Group IV manifested a permanent unilateral labyrinthine weakness. Causation of vertigo by migraine was implied in 10 of 19 cases where the headache and vertigo occurred simultaneously and in two other cases where the vertigo improved with anti-migraine prophylactic treatment.

Four distinct and characteristic vertigo syndromes have been noted with migraine. Their spectrum ranges from a transient reversible dysfunction to a more permanent destruction, and includes involvement of both the peripheral and the central vestibular systems.

Alar (external valve) collapse may be iatrogenic or can occur as a consequence of ageing or trauma. We have utilized an autogenous cartilage graft inserted as an underlay graft to the alar rim to treat 17 patients who have presented with nasal obstruction due to alar collapse. We report the short- and medium-term functional results and the cosmetic sequelae of our approach and conclude that this procedure offers an improvement in nasal airway performance in patients with external valve collapse without producing serious adverse cosmetic sequelae.

Frequently, the clinical picture in the oropharynx alone does not lend itself to a reliable differentiation between acute pharyngotonsillitis in infectious mononucleosis and a streptococcal inflammation. Such a differentiation, however, is essential for the indication of antibiotic therapy. Therefore, it was the aim of the present study to investigate whether or not endoscopic verification of larger-than-normal lymphatic tissue with fibrinous membranes in the nasopharynx would enhance the reliability of diagnosis.

Fifty hospitalized patients exhibiting the clinical picture of acute pharyngotonsillitis were examined for the following parameters: nasopharyngeal endoscopy, determination of glutamine-oxaloacetic transaminase (GOT), glutamine-pyruvic transaminase (GPT), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), leucocytes and haemogram, antibodies to viral capsid antigen (VCA)-IgM, Epstein-Barr virus nuclear antigen (EBNA), and cytomegalovirus (CMV).

In 24 patients with acute tonsillitis/peritonsillar abscess, and in 26 patients with infectious mononucleosis, the total leucocyte count in the blood and the blood/erythrocyte sedimentation rate were comparable. Atypical lymphocytes or absolute lymphocytosis were not seen in acute tonsillitis, but were found in 88.5 per cent of patients with infectious mononucleosis. Elevated transaminase levels were noted in 77 (GOT) and 88.5 per cent (GPT) of patients with infectious mononucleosis, and in acute tonsillitis in 4.2 (GOT) and 12.5 per cent (GPT) of patients. The CRP was higher than normal in 91.7 per cent of patients with acute tonsillitis, and in 57.7 of patients with infectious mononucleosis. In none of the patients with acute tonsillitis was lymphatic tissue with fibrinous membranes seen in the nasopharyngeal cavity. In contrast, nasopharyngeal endoscopy in infectious mononucleosis was positive in 24 out of 26 patients. Hence, the sensitivity was 92.3 per cent, the specificity 100 per cent, and the prediction value for a positive test turned out to be 1.

Endoscopy of the nasopharngeal cavity employed as a simple and supplementary procedure adds to the reliability of diagnosis of infectious mononucleosis.

Irrigation with isotonic saline is one of the most frequently used solutions after nasal surgery. However, the effect of saline solutions on mucociliary clearance is not well known. In a previous study, it was found that isotonic saline solution had a negative effect on ciliary beat frequency but Ringer-Locke solution had no effect in vitro. In this study we compared the effects of Ringer-Lactate solution and isotonic saline solution on mucociliary transport time before, and after, nasal septal surgery in patients with nasal septal deviation. We found that patients who used Ringer-Lactate solution as irrigation after surgery had a significantly better mucociliary transport time than the patients using isotonic saline solution (p < 0.05). In conclusion, it is better to use Ringer-Lactate solution instead of 0.9 per cent saline solution for nasal irrigation.

The objective of this study was to determine the presence of oestrogen and/or progesterone receptors in laryngeal pyogenic granulomas and the impact of these receptors on recurrence of pyogenic granulomas.

Twenty-two consecutive patients who underwent microlaryngoscopy and removal of pyogenic granulomas were studied retrospectively. The indications for surgery were airway compromise, failure of medical therapy and suspicion of malignancy. Twelve of these patients’ granulomas were analysed for oestrogen and progesterone receptors.

Charts were analysed for age, sex, location of the lesion, history of trauma, intubation or gastroesophageal reflux disease (GORD), airway symptoms and recurrence. Oestrogen/progesterone receptors were analysed following deparaffinization of specimens and immunostaining with prediluted anti-oestrogen receptor monoclonal antibody and anti-progesterone receptor monoclonal antibody.

No sample expressed oestrogen or progesterone receptors. There were too few recurrences to detect if lack of these receptors played any role in determining outcome in this group. Most of the patients had a history of GORD, intubation or laryngeal surgery. There were 12 recurrences in four patients. All of the recurrences improved on prolonged courses of omeprazole.

Pyogenic granulomas do not possess oestrogen or progesterone receptors and are unlikely to respond to hormonal therapy. Patients who have, or are being operated on for, laryngeal pyogenic granulomas should be placed on proton pump inhibitors to decrease the likelihood of recurrence.

The anti-tumour effect of the angiogenic inhibitor TNP470, σ-(chloro-acetyl-carbamoyl) fumagillol, a synthetic analogue of fumagillin, was studied in vitro and in vivo using KB cells, one of the human head and neck carcinoma cell lines that produce interleukin(IL)-8. In the in vitro study, the combination treatment of TNP470 and anti-IL-8 antibody significantly reduced the proliferation of KB cells. In the in vivo studies, TNP470 administration by any route (intratumoral: it, intraperitoneal: ip, intravenous: iv) reduced the tumour volume significantly, compared to the control group. Among the groups administered TNP470, the anti-tumour effect was strongest in the it group. Furthermore, the concurrent treatment of anti-IL-8 antibody and TNP470 also maximally reduced the tumour volume. The combination therapy of TNP470 and anti-IL-8 antibody was very effective. These results suggest that combination therapy of TNP470 and anti-IL-8 antibody could be beneficial for solid tumours, such as head and neck cancer.

Cervical lymphadenectomy of level II encompasses lymph nodes associated with the upper internal jugular vein and the spinal accessory nerve (SAN). Removal of tissue superior to the SAN (submuscular recess-(SMR)) was recently shown to be unwarranted in selected cases of squamous-cell cancer. Thirtyfive patients with non-squamous-cell cancer (SCC) of the head and neck treated with cervical lymphadenectomy were prospectively evaluated. Thirty-seven neck dissection specimens were histologically analysed for the number of lymph nodes involved with cancer. At the time of surgery, level II was separated into the supraspinal accessory nerve component (IIa) and the component anterior to the SAN (IIb).

Neck dissections were most commonly performed for cancer of the thyroid gland (19) followed in frequency by the parotid gland (seven), skin: melanoma (five), basal-cell cancer (two), and other sites (four). Twenty-five neck dissections were modified-selective procedures and 12 were either radical or modified radical neck dissection. Twenty-nine necks were clinically N+ and eight N0. Histological staging was pathologically N+ in 32 neck dissection specimens. Level IIb contained an average of 12 nodes and the IIa component contained a mean of 5.0 nodes. Level II contained metastatic disease in 28 of 32 histologically node-positive specimens (87 per cent). Level IIa was involved with cancer in six cases (16 per cent), five of which were pre-operatively staged as clinically N+. All cases (100 per cent) with level IIa involvement had level IIb positive nodes. Three of the level IIa positive cases were cancer of the parotid gland comprising 43 per cent of this sub-group of patients.

Incidence of involvement of SMR in non-SCC cases is not uncommon. The additional time required and morbidity associated with dissection of the supraspinal accessory nerve component of level II are probably justified when performing neck dissection in cancer of the thyroid gland. The SMR should be excised in cancer of the parotid gland. Large-scale prospective controlled studies with long-term follow-up periods are necessary to support resection of level IIb only.

A minimum dataset for recording of findings during myringotomy and ventilation tube insertion for cases of otitis media with effusion is presented. With increasing pressures on surgeons to audit existing practices and hence improve standards of health care, it is appropriate to produce such a set of guidelines for a surgery that is frequently performed world-wide. We believe that the data presented is not too exhaustive and can be readily incorporated into the operative notes.

Only eight cases of bilateral middle-ear squamous cell carcinoma (SCC) have been reported to date. We present the case of a 75-year-old male with bilateral middle-ear SCC and review the previously reported cases. The patient was diagnosed as having moderately-differentiated SCC in the left middle ear in February 1995 and well-differentiated SCC in the right middle ear in September 1997. He initially received radiation therapy with 60Co pendulum (64 Gy) in the left ear and was subsequently treated by Liniac irradiation (50 Gy) in the right ear. He has now been followed up at our ENT clinic for 29 months without vertigo or facial nerve palsy since the second radiation therapy. Although he has a residual tumour in the right middle ear invading the middle cranial fossa dura, no sign of recurrence has been detected in the left ear.

The incidence of acute epiglottitis in children has declined with the introduction of the Haemophilus influenzae b vaccine in 1992. We report a case of acute epiglottitis in a child secondary to an immunocompromised state. We suggest that when acute epiglottitis is diagnosed in a child we should ensure there is no underlying predisposing condition.

Laryngeal cleft anomalies are rare congenital defects of the posterior laryngotracheal wall that usually present with a history of recurrent respiratory tract infections during the early neonatal period. Presentation of type I clefts can be subtle and subsequently can result in late diagnosis or indeed failure to present. We report on the case of a type I laryngeal cleft presenting with a history of recurrent lower respiratory tract infections and severe gastro-oesphageal reflux disease, at 19 years of age. This is the oldest documented initial presentation of a congenital laryngeal cleft, and emphasizes the importance of maintaining a suspicion of the diagnosis into early adulthood. We further highlight the role of gastro-oesophageal reflux disease in the presentation of laryngeal clefts.

Acute post-operative pulmonary embolism is a serious potentially life-threatening complication which is not anticipated in young patients undergoing non-major surgery. We report a case in which a 32-year-old previously healthy woman developed a major pulmonary embolism following tonsillectomy. Subsequent investigations revealed the presence of an occult malignancy. This case highlights the role of paraneoplastic hypercoagulable states in the aetiology of venous thromboembolism and the importance of thromboprophylaxis in the presence of confirmed or suspected malignancy. To our knowlege no case of major pulmonary embolism occurring after tonsillectomy has been previously reported.

Cat-scratch disease (CSD) is a relatively common entity, particularly in children. The most common sites of involvement are the axillary lymph nodes, followed by cervical, pre-auricular and submandibular lymph nodes. We present a case of cat-scratch disease in which the initial clinical features were indistinguishable from those of acute bacterial tonsillitis with jugulodigastric lymphadenopathy. This previously unreported apparent mode of presentation is discussed with reference to the current understanding of the disease.

The majority of salivary gland tumours present as a single mass in one gland. Sometimes multiple primary neoplasms can be seen in more than one salivary gland. The most common tumour is Warthin’s tumour. Multiple primary pleomorphic adenomas are extremely rare. Most of them are in the major salivary glands. The author reports the first case of simultaneous pleomorphic adenomas in the parotid gland and minor salivary gland at the parapharyngeal space.

Solitary fibrous tumours are rare tumours originally described in the pleura. More recently there have been reports of these tumours arising at other sites including the parotid region. They are characterized histologically by a variety of growth patterns that can be confused by the unwary with other benign or malignant tumours particularly sarcomas. We present a case occurring in the pre-auricular region which presented diagnostic difficulties.

Granular cell tumour is a rare neoplasm that can occur in various sites. This report describes a 48-year-old female with a malignant granular cell tumour originating from the cervical sympathetic nerve trunk, who presented with hyperaesthesia of the left shoulder. The tumour had a maximum diameter of 86 mm and involved adjacent tissues directly.

Histopathologically, it showed considerable variation in the size and shape of nuclei, with occasional mitosis and an abundant granular cytoplasm. Immunohistochemically, the tumour reacted positively for S-100 protein and neuron-specific enolase, indicating its neural origin. Following total local excision of the lesion, the patient has been well without recurrence.
