Frederick III (Crown Prince of Prussia, and Emperor of Germany) died of cancer of the larynx in 1888. In Drame Imperial (1888) journalist Jean de Bonnefon asserted that the disease was not cancer but syphilis which the Crown Prince acquired in 1869 in Suez. What de Bonnefon wrote about the prince does not coincide with the prince's itinerary published in the London Times. This discrepancy is examined and the reason for de Bonefon's claim is considered. The report that Crown Prince Frederick of Prussia caught syphilis in Suez is a canard.

Following laryngectomy patients are usually advised that swimming is no longer possible. Under supervised conditions and using a swimming aid, such as described, a laryngectomee may return to an activity previously considered unavailable, rehabilitation thus being more complete. However, for a laryngectomee to proceed a safe supervised environment is required, and the path to this goal is often long and arduous, but with persistent dedication the Laryngectomy Swimming Club may become a reality bringing rich reward.

Research on the eustachian tube (ET) and related paratubal structures was carried out by serial section of the temporal bone-ET specimens. In the cadaveric studies, the mid-cartilaginous section of the ET presented a curved slit-like lumen. It is believed that this section functions principally as a valve mechanism and acts like an active sphincter of the ET. This report illustrates the dynamic movement of the valve section in a living ET which can be observed by using a superfine fibreoptic videomicroendoscope. Disorders of the open-close mechanism of the valve section in a diseased ET due to different aetiologies are also discussed. This study indicated that transtympanic ET microendoscopy had considerable potential for exploring fascinating new aspects of the physiology, pathophysiology and anatomy dynamics of the ET.

Mast cells are a rich source of potent biologically active mediators and are found in connective tissue, associated with blood vessels in many varied inflammatory conditions. Mast cells have been described in nasal polyps and turbinates and in adenoidal tissue in the upper aerodigestive tract. As the middle ear lining is contiguous with the nose and the nasopharynx, the presence of mast cells in aural polyps is interesting.

This preliminary study investigated the presence of mast cells in inflammatory aural polyps using light microscopy. All patients presenting to the department in one year were included. Patients with previous ear disease or surgery and in whom cholesteatoma was suspected were excluded. Except for one patient mast cells were seen in all aural polyps. The implications of these findings is discussed. Further work is needed using electron microscopy.

A prospective study on the dynamics of tympanic membrane atelectasis during the treatment for glue ear was performed in a sample of 115 ears of 83 children aged between one and 11 years. The progression in the degree of pars tensa atelectasis was analysed in relation to six potentially relevant factors. Multivariate analysis showed that the factor with the most predictive value on the progression of the pars tensa retraction was the grade of atelectasis at initial detection (p<0.0001). The use of grommets did not have any significant influence on the outcome grade of atelectasis. There was an association between previous grommet insertion and localized retractions in the inferior segment of the pars tensa (P<0.0001). However, localized retractions in the postero-superior quadrant were not associated with previous grommet insertion (P<0.02). Although the hearing thresholds of atelectatic ears were significantly worse than normal ears especially at 4 kHz (p<0.006), the difference was less than 5 dB.

The aetiology of Menière's disease (MD) remains obscure, but is likely to be multifactorial, one of the factors being a genetic predisposition. Forty-one families with more than one living member with MD were ascertained and affected and normal relations examined. Blood was collected and DNA extracted and stored. In these families the mode of inheritance is autosomal dominant, the penetrance of the mutation being about 60 per cent. Some of the family members exhibit a partial syndrome, vestibular symptoms predominating. Sporadic and familial cases exhibit the same clinical features. The striking finding is the phenomenon of anticipation, whereby with successive generations there is an earlier age of onset and a tendency to more severe manifestation. The inference, considering that the cells which regulate endolymph are of neuroectodermal origin, is that, like other neurodegenerative disorders which show anticipation, MD manifestation is likely to be related to trinucloetide expansion within a gene.

Simple rhinohygrometry and passive rhinomanometry studies have suggested that the ‘nasal cycle’ in children is often different in pattern of that of adults and experimental animals. We aimed to establish whether this assertion was correct, using a reliable and sensitive method, acoustic rhinometry (AR), and to compare results with those of simple rhinohygrometry (RH). Healthy children with no evidence of nasal disease were examined (n = 15; age range three to 10 years; mean age six years). Simultaneous recordings using AR and RH were made on each child every 10–15 minutes over two to four hour periods. Six children underwent nine additional AR studies on separate occasions. ‘Classical’ reciprocal alternating patterns were evident in 80 per cent (12/15) AR and 53 per cent (8/15) RH studies, ‘in concert’ patterns in seven per cent (1/15) AR and 20 per cent (3/15) RH studies and ‘irregular’ patterns in 13 per cent (2/15) AR and 27 per cent (4/15) RH studies. The agreement between the two methods was 47 per cent, with a kappa (K) value of −0.17 (poor agreement compared to chance). Agreements between the acoustic rhinometry parameters were ‘fair’ for all data (K = 0.34) and excellent (K = 1.0) if irregular patterns were ignored. Repeated studies showed that the pattern of fluctuation varies within any particular individual. The nasal cycle is similar in pattern in children and adults, and acoustic rhinometry is currently the method of choice to further investigate and clarify this phenomenon.

Acute and chronic infections cause morphological changes in the respiratory mucosa. The ultrastructure of human respiratory mucosa was studied by scanning electron microscopy from the maxillary sinuses of 28 patients, with chronic sinusitis, from middle turbinates of 60 patients, with recurrent respiratory infections, and from healthy sphenoidal sinuses of 31 patients. A loss of ciliated cells and an increasing number of nonciliated columnar cells with microvilli were seen in 62 per cent of the maxillary sinus mucosa. Ciliary disorientation was seen in 81 per cent of the chronically infected sinus mucosa and eight per cent in the healthy sphenoidal sinuses. Also metaplasia and extrusion of epithelial cells were prominent in chronic infections. Compound cilia were seen in 52 per cent of the samples from patients with chronic sinusitis and in 31 per cent of the healthy sphenoidal sinuses. Short cilia were often seen in infected mucosa indicating ciliogenesis.

We report the results of a prospective pilot study of 54 adult patients undergoing tonsillectomy using the KTP-532 laser, designed to assess whether the technique would facilitate day-case adult tonsillectomy. Subjective and objective assessment at six hours post-operatively showed that only 43 per cent could, in our judgement, have been discharged at this interval. Furthermore, the overall complication rate was 31 per cent with a secondary haemorrhage rate of 19 per cent. We conclude that KTP-532 laser tonsillectomy as performed in this pilot study compares unfavourably with dissection tonsillectomy and we discuss possible reasons for this.

Two patients presenting to the Central Military Hospital of Beirut with symptomatic lingual thyroid are reported. I131 thyroid scanning revealed the lingual thyroid to be the only functional thyroid tissue present in each patient. Subsequent CT scanning demonstrated the large size of these ectopic thyroids causing significant mechanical obstruction. These were excised transorally using a posterior midline tonguesplitting incision and reimplanted in the rectus abdominis muscles.

Details of this modified tongue-splitting surgical approach are described. A brief review of the literature concerning lingual thyroid and its surgical treatment is also presented as well as three patients operated on for lingual thyroid at the American University of Beirut Medical Centre between 1975 and 1994 using an external neck incision.

Non-tuberculous mycobacterial (NTM) infections in children commonly present as cervicofacial masses. The importance of early diagnosis is in the exclusion of infection requiring treatment, particularly tuberculosis and the rare case of malignancy. Five children with NTM presenting with salivary gland masses illustrate the value of skin testing with new tuberculins and the place of fine-needle aspiration cytology in the investigation of these infections.

Four children who were skin tested reacted specifically to one of the new tuberculins, two indicating infection with Mycobacterium malmoense, confirmed by culture, the others responding to tuberculins from M. scrofulaceum and M. avium-intracellulare, neither having a positive culture. The one case not skin tested produced M. avium-intracellulare on culture.

All five patients were managed conservatively. The place for conservative management when the facial nerve is at risk and extensive skin excision is indicated are discussed.

We became aware that a range of antibiotics were being used in our unit to treat patients suffering from tonsillitis or peritonsillar abscess (quinsy). There appeared to be no rationale to determine which antibiotics were used, and we felt that we were possibly using expensive antibiotics when cheaper equally effective ones were available. An audit project was therefore devised to establish the current practice in the ENT Unit at the City Hospital at Edinburgh. Following a six-month prospective pilot study, a protocol for the treatment of tonsillar and peritonsillar sepsis was drawn up and subsequent practice and outcome was then audited, thus completing the audit cycle. As a result substantial savings in the cost of prescribed antibiotics have been made without compromising patient care.

Impaction of a fish bone at the base of tongue or the vallecula is a very common problem. Removal of the bone from these sites without a general anaesthesia can be challenging to surgeons and patients alike. Various manoeuvres to facilitate this procedure have been described, some are very successful but may require specialized instruments, while others may cause excessive discomfort to the patients and even inadvertent dislodgement of the bone. We describe a method using a flexible fibreoptic nasendoscope to provide a visual guide in order to facilitate peroral removal of the bone with a pair of forceps. This method is well tolerated by patients and avoids the need for a general anaesthesia in many cases.

Control and recording of the position of the acoustic rhinometer in relation to the nostrils is important for serial measurements. Several technical factors must be controlled, including the angle of the incident acoustic wave. We describe a simple, newly-designed, rhinometer stand which allows control of height and angle, and hence improves the reliability of serial measurements in clinical and physiological work.

We report a case of giant cell tumour of the temporal bone arising in a 31-year-old man. The presenting symptoms were unusual, being rotational vertigo, unilateral tinnitus, and hearing loss. A computed tomography (CT) scan showed a large mass within the right temporal bone and the infratemporal fossa. The radiological appearance was suggestive of an aggressive primary neoplasm arising within bone. Biopsy and subsequent resection showed a giant cell tumour of bone. The tumour was histological grade 1. At two-year follow-up, there was no evidence of tumour recurrence or metastasis.

We present a cochlear implant failure previously unidentified and unreported. Following successful implantation and activation of a Cochlear Mini 22 system, a distressing barrage of crackling noises was heard by the patient despite repeated programming with threshold and comfort level adjustment. The implant soon became nonfunctional and integrity testing showed deficient electrical responses and abnormal surface measured wave forms. Investigation of the explant, following reimplantation with an identical system, showed a defective trim capacitor, an electric component of the internal circuit in the stimulator. Paired Student's t-test showed a marginally significant increase (p = 0.047) in effective threshold level and a highly significant decrease (p = 0.0002) in maximum comfort level for the second implant compared to the first implant.

We report on a patient with an intramedullary lesion who showed only symptoms of so-called vestibular neuronitis. From the neurological aspects and MRI findings, the lesion was thought to be localized to the vestibular nerve in the pons. Cerebrospinal fluid testing and MRI findings suggested a diagnosis of multiple sclerosis (MS), although the clinical features were not compatible with MS. This case may shed some light on the aetiology of vestibular neuronitis.

We present a case of superficial siderosis (SS) of the central nervous system (CNS) with an unruptured intracranial aneurysm to illustrate that the commonly encountered unexplainable progressive sensorineural hearing loss (SNHL) can be an important sign for the early awareness of this rare disorder. The literature on SS is reviewed and the pathogenesis of SS is discussed.

The aetiology of antrochonal polyps is unknown. We report one case where treatment with topical intranasal cortico-steroids was successful. We are not aware of any previous reports of medical treatment.

Giant cell reparative granuloma is a benign lesion occurring most commonly in the bones of the jaw and rarely in the paranasal sinuses. We present an unusual case of giant cell reparative granuloma arising within a concha bullosa. Complete excision was achieved using an endoscopic transnasal approach.
