KTP-532 laser tonsillectomy--a potential day-case procedure?

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.

Giant cell reparative granuloma of the concha bullosa.

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.

Skin tethering after dilatational percutaneous tracheostomy.

Percutaneous tracheostomy is increasingly preferred for patients in the Intensive Care Unit. It is a convenient method with a low incidence of complications. Skin tethering has not previously been emphasized as a complication of this technique and, although primarily cosmetic, may result in significant morbidity.

Technical note: computed tomographic dacryocystography.

The technique of computed tomographic dacryocystography is described. It was developed in response to the pre-operative imaging requirements for transnasal endoscopic dacryocystorhinostomy, a new minimally invasive operation performed as a primary procedure to relieve epiphora. However, it is also helpful in the assessment of patients after failed conventional external dacryocystorhinostomy when the information provided will help to determine the subsequent surgical approach. In addition the technique will assist surgical planning in cases of epiphora associated with sinus surgery, facial trauma and maxillofacial tumours by determining the site and extent of pathology.

Infraorbital nerve dehiscence: the anatomic cause of maxillary sinus "vacuum headache"?

Vacuum disorders of the paranasal sinuses are well described. Patients with facial pain in the distribution of the infraorbital nerve are often labelled as suffering from a "vacuum maxillary sinusitis" and empirically treated by intranasal antrostomy. A variety of mechanisms have been postulated for the production of symptoms in this condition, but all ignore the fact that the maxillary sinus is a relatively insensitive structure. This article introduces a dehiscence of the bony infraorbital nerve canal within the antrum as an anatomic variant and suggests that it may provide the anatomic basis for vacuum sinusitis in the presence of a small natural ostium. Definitive diagnosis is made by outpatient antroscopy, and surgical treatment takes the form of a middle or inferior meatal antrostomy. Persistent symptoms may benefit from an infraorbital neuropexy to provide added protection to the exposed nerve.

Styloid apparatus anomaly causing dysphagia.

An unusual case of dysphagia due to anomalous styloid apparatus anatomy is presented. Clinical and radiological findings are documented. Variations in anatomy and clinical syndromes are discussed together with management.

Serum cotinine as an objective marker for smoking habit in head and neck malignancy.

Cigarette-smoking is a well-established aetiological factor in squamous cell carcinoma of the larynx. In Great Britain the majority of patients with laryngeal cancer are treated by radiotherapy with salvage surgery if necessary. A troublesome side effect of radiotherapy is mucositis which may exacerbate hoarseness, dysphagia, airway obstruction or pain. Although it is a common belief that continued smoking and alcohol consumption during radiotherapy may increase the frequency and severity of these side effects this has not been demonstrated objectively. This study confirms and illustrates the relationship between such radiotherapy reactions to continued smoke exposure by using an objective biochemical marker of smoking status.

Polytomographic radiology in the diagnosis and management of maxillary antral disease as determined by antroscopy.

Plain radiology of the maxillary sinus correlates poorly with pathological conditions affecting it as shown by subsequent endoscopic assessment. Tomographic radiology provides a much higher diagnostic yield and in particular is of great value in assessing the 'opaque antrum'. The false positive rate is similar in the two techniques but tomography yielded no false negative diagnoses in this study compared with an incidence of 31% with plain radiology. Sinoscopy remains the definitive method of assessing antral disease but tomographic radiology is a highly accurate screening technique. It provides this accuracy at low cost, low orbital irradiation and more convenience than the newer techniques of CT and MRI scanning which are still not widely available for routine ENT use.

Heterotopic brain tissue: a rare cause of adult recurrent meningitis.

Heterotopic brain tissue is a rare cause of symptoms in neonates in whom it may present with respiratory obstruction. In infants it may produce unilateral nasal obstruction due to a nasal 'polyp' or cerebrospinal fluid rhinorrhoea with an associated risk of meningitis. It is exceedingly rare in adults but may nevertheless be a cause of significant morbidity as this case demonstrates.

Epistaxis as an unusual presentation of an antrochoanal polyp.

Antrochoanal polyps rarely present with severe epistaxis. We present the case of a young male patient who presented in such a manner, thus leading to the suspicion of an angiofibroma as the underlying pathology. The radiological investigations, treatment and pathological features are discussed.

Non-infective orbital complications resulting from natural defects of the antral roof. Case report.

Infective complications of paranasal sinus disease presenting within the orbit are not uncommon. They may be facilitated by bony defects of the orbital floor or antral roof which may also allow non-infective complications to occur. These may occur spontaneously or may follow operative procedures upon the antrum and must therefore be borne in mind when performing such procedures. We present representative clinical examples of these non-infective complications.

The lingual tonsil. A neglected symptomatic structure?

Surgical treatment of the lingual tonsil is seldom performed because problems attributable to chronic lingual tonsillar hypertrophy are infrequently diagnosed. We have reviewed a series of 25 patients with symptoms from enlarged lingual tonsils. The variety of presentation of lingual tonsillar lesions and the methods of surgical treatment are discussed.

Symptomatic mucosal cysts of the maxillary sinus: antroscopic treatment.

Antroscopy has been shown to have a role in the diagnosis and treatment of antral disease. Four cases of 'non-secreting' benign antral cysts, each presenting with facial pain, were successfully treated using antroscopic techniques. The aetiology and management of these lesions is reviewed with the recommendation that antroscopic removal is the treatment of choice for all symptomatic cases, and for asymptomatic cases in which the diagnosis is in doubt.

Antroscopy: a comparison between the sublabial (canine fossa) and intranasal (inferior meatus) approaches as an out-patient procedure.

We present a prospective randomized study comparing two approaches for out-patient antroscopy. The traditional inferior meatus route was seen to be associated with a higher incidence of discomfort and significant complications. An alternative route via the canine fossa provided easier access, better patient tolerance and improved visualization of the antral contents. It was associated with a lower incidence of immediate complications, although there were a number of delayed symptoms, all of which were mild and transient. The canine fossa approach under local anaesthesia offers an effective and more acceptable alternative for antroscopy as an out-patient procedure.
