Until recently the practice of otological procedures on cadaver temporal bones was a common occurrence in otolaryngology departments. The difficulty in acquiring specimens has led to alternative techniques which involve artificial and computer-aided models. This article looks at the present situation in these rapidly developing areas and describes an artificial model developed by the senior author for training in middle-ear procedures.

Snoring is a significant problem with both social and medical manifestations. This article addresses the current management of the simple snorer from initial out-patient assessment to definitive treatment.

Little is known of the aetiology, serotypes or susceptibility of the pathogens causing non-resolving otitis media in children receiving care from specialists in private practice in developed or in developing countries. Increased access to antibiotics in the community amongst children receiving such private care in South Africa may be anticipated to lead to levels of resistance similar to those found in countries with similar models of private practice, such as the United States. This study was conducted to determine the aetiology of non-resolving otitis media in South African children receiving private care and to determine the antimicrobial resistance patterns and serotypes of the bacterial isolates.

Middle-ear fluid was cultured from 173 children aged two months to seven years with non-resolving acute otitis media accompanied by persistent pain or fever who were referred to otorhinolaryngologists for drainage of middle-ear fluid within 14 days of the start of symptoms. While 92 per cent of the children had recently received antibiotics and 54 per cent were currently receiving them, bacteria were isolated from 47 children (27 per cent). Streptococcus pneumoniae was the most common pathogen (35), followed by Haemophilus influenzae (nine), Staphylococcus aureus (six), Moraxella catarrhalis (two), Streptococcus pyogenes (two) and Pseudomonas aeruginosa (one). Two isolates were identified in each of eight children. Antimicrobial resistance to one or more antibiotics was found in 33/35 (94 per cent) of the pneumococci isolated, with resistance to penicillin in 86 per cent, resistance to trimethoprim-sulfamethoxazole in 54 per cent and to erythromycin and clindamycin in 69 per cent and 57 per cent, respectively. The pneumococcal serotypes found were 19F (28 per cent), 14 (26 per cent), 23F (23 per cent), 6B (nine per cent), 19A (87 per cent), and four (three per cent). Children with a bacterial pathogen isolated were younger (mean age of 17 months) than children from whom no bacteria were isolated (mean age of 23 months; p = 0.03). Isolation of a pneumococcus was also significantly associated with younger age (mean = 16 months versus 22 months, p = 0.03), the presence of fever (OR = 2.15, p = 0.049), and having one or more prior episodes of otitis media within the six months before tympanocentesis (OR = 7.72, p = 0.03). Almost all pneumococci isolated from non-resolving acute otitis media in this community are antibiotic-resistant and should be considered especially in young children who have failed previous therapy and who have non-resolving pain or fever.

The aim of this retrospective study was to determine the possible causes of failure of antibiotic therapy in children with acute otitis media (AOM). Thirty-nine samples of middle-ear fluid were obtained by myringotomy from 31 children suffering from AOM, unrelieved by antibiotic therapy administered for over 48 hours. The samples were analysed by the usual microbiological techniques, including cultures, tests for beta-lactamase producing strains and the determination of the minimal inhibitory concentration of penicillin for Streptococcus pneumoniae. In 14 samples, no bacterial strains were detected in the cultures of middle-ear fluid; and in two samples the cultures revealed two strains of bacteria. The bacteria most frequently identified were Haemophilus influenzae, found in 11 samples, and Streptococcus pneumoniae, found in seven samples, of which four produced strains with reduced susceptibility to penicillin. The failure of antibiotic therapy in AOM appears to be related to the increased resistance of Haemophilus influenzae and to the reduced susceptibility of Streptococcus pneumoniae to penicillin. Other factors contributing to the failure of antibiotic therapy in AOM may be the viruses or the bacteria that produce multiple pathogens in the middle ear.

Fifty-two children with mastoiditis were treated at the Federal Government Services Hospital over a period of 15 years (from 1986 to 2000). The salient feature in these cases was the presence of a post-auricular swelling and mastoid abscess. Extensive cholesteatoma was seen in 80.7 per cent of cases and 19.3 per cent had granulations in the mastoid cavity. Significantly, all patients had a history of chronic ear discharge prior to abscess formation. These children belonged to poor communities, were malnourished and attended hospital in a state of emergency.

The presentation and course of the disease confirms the aggressive and potentially serious nature of the pathology requiring early medical attention in order to avert impending complications. It appears that in our environment acute mastoiditis with abscess formation develops from chronic otitis media and the cholesteatoma. The surgical procedures conducted in these cases were radical and modified radical mastoidectomy.

Myringostapediopexy may occur as a result of incus erosion with medialization of the tympanic membrane and is recognized as often producing serviceable hearing. The technique may be used as part of tympanoplasty following either canal wall up or canal wall down surgery for chronic otitis media. The use of this type of reconstruction is influenced by the anatomy of the ear after disease excision. This review of the hearing levels associated with myringostapediopexy shows that there is a similar range of hearing level both for naturally formed as well as surgically fashioned myringostapediopexy. For both ’naturally formed’ and following canal wall up surgery about 80 per cent of patients will have an air-bone gap of 20 dB or less compared to 60 per cent of those who undergo canal wall down surgery.

Informed consent is becoming an increasingly important issue in patient care. Inherent in this is the ability to accurately inform patients of the risks and complications involved in surgery. Nasal septal surgery is commonly performed by otolaryngologists and although often considered routine has a number of recognized complications that can have a significant effect on life quality. We carried out a review of the literature over the last 25 years and reviewed studies quoting rates of complications after septoplasty and submucous resection (SMR) using strictly applied criteria for study inclusion. There was a paucity of prospective data, especially for the cosmetic effects of septal surgery. Rates of septal perforation were two to eight per cent for SMR and 1.6–5.4 per cent for septoplasty. The incidence of cosmetic deformity was low for both procedures zero to one per cent. More well-designed studies are required to augment the current evidence base. While this does not replace the need for surgeons to audit their own results it provides evidence-based information to assist in the process of informed consent.

This paper attempts to evaluate the clinical usefulness of CYFRA 21-1 as a serum tumour marker in patients with head and neck squamous cell carcinoma (HNSCC).

The serum concentration of CYFRA 21-1 was measured utilizing a new electrochemiluminescent immunoassay (ECLIA) in 142 patients with HNSCC before and after treatment, 68 patients with benign tumours of the head and neck, and 50 healthy controls.

Serum levels of CYFRA 21-1 in patients with HNSCC were significantly higher than those of benign tumours and healthy controls (p < 0.001). The diagnostic sensitivity and specificity of CYFRA 21-1 for HNSCC were 62 per cent and 100 per cent, respectively. The positive rates of CYFRA 21-1 increased with progression of HNSCC, serum CYFRA 21-1 levels were related to the tumour stage expressed by primary tumour (T) and nodal status (N) (p < 0.001), but not related to patient age, gender, smoking and drinking habit, or histopathological grade (p > 0.05). Post-treatment levels of CYFRA 21-1 in HNSCC decreased significantly (p < 0.001). Among 38 patients with clinical or radiological evidence of a recurrence during follow-up, 78.9 per cent (30 of 38) showed an increase in CYFRA 21-1.

The analytical ECLIA performance for serum CYFRA 21-1 provides a new means of clinical assessment for HNSCC. The results of ECLIA suggest that the serum marker CYFRA 21-1 is valuable not only for diagnosis but also for close monitoring of patients with HNSCC.

We describe an endaural technique for soft tissue and bony meatoplasty and canalplasty in the surgical management of chronic otitis externa unresponsive to medical treatment and out-patient microsuction. Following analysis of the surgical outcome via a retrospective review of patient records, we would recommend this surgical treatment in this patient group.

Bleeding is a dangerous complication of thyroid surgery. We describe a new technique of vessel and tissue sealing and bleeding control using an electrothermal sealer. The technique has some potential advantages over the current methods used for this purpose.

We report a case of mucoepidermoid carcinoma (MEC) originating from the eustachian tube and middle ear. A 31-year-old male who presented with otorrhoea and methicillin-resistant Staphylococcus aureus (MRSA) in the right ear was admitted to hospital due to cerebral infarction and deep vein thrombosis. After recovery, biopsies from a granulomatous mass found in the middle ear during operation for chro ic otitis media revealed intermediate-grade MEC and a nasopharyngeal mass identified after surgery also revealed the same result. He received combined radiation therapy and chemotherapy and no residual or recurrent tumour was detected after two years of follow-up.

The case of a five year old boy who presented with a lower motor neurone facial nerve palsy secondary to primary non-Hodgkin’s lymphoma (NHL) of the middle ear is discussed. Any child who presents with a facial nerve palsy and conductive hearing loss requires thorough evaluation to exclude the possibility of temporal bone malignancy.

A case of Wegener’s granulomatosis (WG) presenting with hearing loss and right facial nerve palsy is reported. The definitive diagnosis was based upon clinical data and serum cANCA and AECA detection. Early assessment of WG prevented surgical facial nerve decompression to treat a chronic otitis media complication. Immunosuppressive therapy with steroids, cyclophosphamide and methotrexate was required for relief of clinical symptoms and cANCA negativity as an expression of disease remission. The effectiveness of co-trimoxazole for preventing relapses of WG is discussed.

Inner ear involvement with sensorineural hearing loss (SNHL) has been reported in many autoimmune disorders including ulcerative colitis. The pathogenetic mechanism of hearing loss in ulcerative colitis is thought to be immune mediated. Diagnostic tests are being developed to identify inner ear autoantibodies, that may be the cause of such hearing loss. The only test that is currently available for clinical use is the Otoblot test. This, however, tests only for antibodies against bovine heat shock protein 70 which is only one of the many cross-reacting proteins against the inner ear in suspected immune-mediated hearing loss. The clinical response to steroid therapy is thus the mainstay in the diagnosis of immune-mediated hearing loss. This paper presents a series of patients with clinically suspected autoimmune hearing loss. Diagnostic assays for this condition are discussed along with a review of the recent advances in the pathogenesis and laboratory diagnosis of immune-mediated sensorineural hearing loss.

A rare case of incomplete tracheal duplication with severe unilateral lung hypoplasia is presented. Photo-documentation of the gross post-mortem specimens is presented so that the anatomical aspects of this unusual anomaly can be recognized and appreciated. Clinical information is presented in the hope that successful premorbid identification of potential complications of this anomaly could be made by future physicians. To our knowledge, this is the first reported case of pathologically-confirmed duplication of the trachea.

Two rare cases of benign submucosal pharyngo-oesophageal mesenchymoma are presented in this paper. One patient was treated by tumour removal via a combined thoracic and laterocervical approach and the other by resection through a laterocervical approach. The paper discusses the pathology and diagnosis of benign mesenchymomas. The authors suggest that for large tumours located in the pharynx and extending down the oesophagus without adhesion to the oesophageal wall, the laterocervical approach can avoid complications associated with the thoracic approach. The new technique caused less tissue damage and provided a quicker recovery and shorter hospitalization.

Superovulation therapy with in vitro fertilization (IVF) treatment may result in ovarian hyperstimulation syndrome and a hypercoaguable state. The site of thrombus formation is commonly in the upper venous extremities. One case of bilateral internal jugular vein thrombosis following ovarian hyperstimulation is described. The clinical presentation, investigations and management are discussed.

With an incidence of less than 0.3 per cent, post-radiation sarcomas are rare malignant neoplasms with a very poor prognosis. On average, they occur after a latency period of at least 15 years following radiation therapy with doses ranging from 24 to 80 Gy. We present the case of a post-irradiation malignant fibrous histiocytoma (MFH) on the floor of the mouth in a 79-year-old male patient arising only five and a half years after radiation therapy. The primary tumour was classified as a well differentiated squamous cell carcinoma of the right rim of the tongue. Primary therapy was surgical resection of the tumour and post-operative radiation with 50 Gy. Five and a half years later, the patient developed a rapidly progressing MFH within the field of radiation.
