(1) To examine the vocal symptoms and acoustic changes perceived in the short period immediately after laryngeal mask airway, and (2) to compare these findings in patients using laryngeal mask airway and endotracheal tube.

A total of 27 patients were enrolled. They were evaluated pre-operatively and then at 2 and 24 hours post-operatively. Patients were divided into two subgroups, laryngeal mask airway and endotracheal tube. Patients were asked about the presence or absence of the following: hoarseness, vocal fatigue, loss of voice, throat-clearing sensation, globus pharyngeus and throat pain. Patients then underwent acoustic analysis of their voice, measuring the average fundamental frequency, relative average perturbation, shimmer, noise to harmony ratio, voice turbulence index, habitual pitch and maximum phonation time.

In the laryngeal mask airway group, there was an increase in the incidence of all vocal symptoms two hours post-operatively, except for globus pharyngeus. The increase was statistically significant for vocal fatigue, loss of voice and throat pain. All the symptoms had reverted back to a normal baseline level by 24 hours. There was a decrease in the maximum phonation time and habitual pitch, with an increase in all the perturbation parameters, two hours post-operatively. At 24 hours, an increase was still present for shimmer, noise to harmony ratio and voice turbulence index. The maximum phonation time and habitual pitch reverted back to normal values.

In the endotracheal tube group, there was a significant increase two hours post-operatively in the incidence of hoarseness, loss of voice and throat pain. At 24 hours, all the symptoms reverted to baseline, except for vocal fatigue and throat pain. Two hours post-operatively, there was a significant decrease in maximum phonation time and an increase in all other parameters (however, the latter was significant only for relative average perturbation and noise to harmony ratio). At 24 hours, there was a significant increase in the maximum phonation time and a persistent (but statistically insignificant) increase in the average fundamental frequency, habitual pitch, noise to harmony ratio and voice turbulence index.

At two hours, there was more loss of voice and vocal fatigue in the laryngeal mask airway group, compared with the endotracheal tube group. At 24 hours, these symptoms were comparable in both groups. Comparing changes in acoustic parameters to baseline values in both groups, there were no statistically significant changes.

Shortly after reversal of anaesthesia, laryngeal symptoms following laryngeal mask airway are no less significant than those experienced following endotracheal tube anaesthesia. Both methods can be regarded as nontraumatic, in view of the lack of significant vocal symptoms and acoustic changes 24 hours after anaesthesia.

Dacryocystorhinostomy via an endonasal route has been adopted in our department. This audit study describes and compares our results for external, laser endonasal and ‘cold steel’ endonasal techniques. Success was defined as a subjective report of eye watering being ‘better’ or ‘cured’. Data were obtained from a retrospective review of the medical records of all patients undergoing primary dacryocystorhinostomy in our department.

External dacryocystorhinostomy performed by a consultant ophthalmologist was taken as our gold standard. In our study, the success rate for external dacryocystorhinostomy was 94 per cent.

Our initial results for endonasal laser-assisted dacryocystorhinostomy produced a success rate of 64 per cent, which was significantly worse than that for external dacryocystorhinostomy. These results have been previously published.

Evidence suggested that cold steel endonasal dacryocystorhinostomy was more effective, and we adopted this as our technique of choice.

Over a four-year period, 57 cases completed a full nine months' follow up. 93 per cent were completed as day cases and 39 per cent were performed under local anaesthetic. The success rate was 79 per cent (45/57). There was no difference in success rates when this procedure was compared with external dacryocystorhinostomy (p = 0.55). The type of anaesthetic used (i.e. local vs general) made no difference to the success rate (p = 0.93).

Cold steel endonasal dacryocystorhinostomy was as effective as the gold standard, i.e. external dacryocystorhinostomy. Laser-assisted dacryocystorhinostomy was significantly less successful than external dacryocystorhinostomy. Due to the benefits of decreased operating time, lower morbidity and success under local anaesthetic, we recommend cold steel endonasal dacryocystorhinostomy as our procedure of choice for the treatment of epiphora.

18F-Fluorodeoxyglucose positron emission tomography can detect cervical metastases before they are palpable. However, false positive results are not uncommon. This paper reports the use of ultrasound-guided fine needle aspiration to determine the nature of impalpable cervical nodes that are positive on positron emission tomography scanning.

Ultrasound-guided fine needle aspiration was performed in 10 cancer patients with suspicious cervical nodes revealed by positron emission tomography scan. Clinical data were retrospectively reviewed.

The underlying cancers included lung cancer (three patients), nasopharyngeal carcinoma (two), oesophageal cancer (two), buccal cancer (one), bladder cancer (one) and Langerhan's histiocytosis (one). The lymph nodes were located in the supraclavicular region in four patients, the level II region in four, the level IV region in one and the accessory chain in one. Cytological examination was positive for malignant cells in eight patients, all of whom received salvage treatment. Two of these patients died of distant metastases. Cytological examination revealed a benign or reactive lesion in two patients, who at the time of writing were alive and well, 19 and 36 months after examination.

Ultrasound-guided fine needle aspiration is a minimally invasive procedure which enables cytological examination of suspicious cervical lymph nodes detected by positron emission tomography scanning, allowing further treatment to be planned.

This study aimed to estimate the effectiveness of a full digital, high definition video system for laryngeal observations.

A newly available, full digital, high definition video camera and high definition video monitor were used. With an endoscopic adaptor and rigid telescope, laryngoscopy and stroboscopy were performed on patients with various kinds of laryngeal lesions.

All laryngeal lesions were observed and recorded by the full digital, high definition video camera without incident. The image quality for laryngoscopy and stroboscopy was far superior to that of a conventional video system, including video-endoscopy. Even tiny structures or lesions could clearly be visualised on the monitor. The still image obtained from the full digital, high definition video camera was 1920 × 1080 pixels and was comparable to that obtained from a still camera.

Full digital, high definition video cameras are now commonplace products and can easily be applied to patients with laryngeal disorders. They provide superior laryngeal images, compared with conventional video systems. Furthermore, high definition video systems are cheaper than proprietary medical video systems. We consider our system to represent an accessible technique of gaining superior laryngeal observation in otolaryngological clinics.

The sacculo-collic reflex is believed to be a short latency, otolith-mediated myogenic response to sound. With the application of air-conducted sound, one would expect an absent response in stapes fixation, as a fixed stapes footplate will not transmit a pressure wave to the saccule.

Fifty patients (70 stapes surgery ears, 26 otosclerotic ears and four normal ears) and 40 controls underwent repeated sacculo-collic tests.

The results support the proposed mechanism for the sacculo-collic response. The study also suggests that, whilst stapedotomy piston prostheses are effective in the reversal of conductive hearing loss, they produce an insufficient pressure wave to elicit a myogenic response to sound.

The sacculo-collic test could be a useful tool for screening otolith function and inferior vestibular nerve integrity, but further work is needed to determine the effect of stapes surgery on saccular function.

Chronic inflammation of sinus mucosa is a multifactorial condition which sometimes results in irreversible pathological mucosal changes.

To evaluate the efficacy of endoscopic radical antrectomy in treating chronic, hyperplastic, eosinophilic sinusitis, and to compare this procedure with classical endoscopic middle meatal antrostomy.

A randomised, controlled trial with parallel design was conducted between July 2000 and December 2004, including 119 patients who fulfilled the clinical, radiological and histopathological criteria for chronic, hyperplastic, eosinophilic sinusitis. Patients were randomly allocated to two treatment groups: classical endoscopic middle meatal antrostomy and endoscopic radical antrectomy. The main outcome measures were recorded in each subgroup at the time of the patient's last clinic visit. In each subgroup, these included subjective improvement and evaluation of the endoscopic appearance of the maxillary sinus.

Thirty-two per cent of patients in the endoscopic middle meatal antrostomy group were considered surgical failures, compared with 14.5 per cent of the endoscopic radical antrectomy group. This was statistically significant (p = 0.023). Unhealthy maxillary sinuses were significantly more prevalent in the endoscopic middle meatal antrostomy group (p = 0.029).

In those patients fulfilling the criteria suggestive of chronic, irreversible sinonasal pathology, primary endoscopic radical antrectomy was significantly better than endoscopic middle meatal antrostomy, based on subjective and objective findings.

A reliable grading system allows the clinician to classify disease severity, monitor progress and evaluate treatment efficacy. There is no currently accepted grading system for vocal process granuloma of the larynx.

To evaluate the reliability of a new grading system for vocal process granuloma.

All vocal process granuloma images from a digital laryngeal image library were abstracted. Granulomas were graded on a one to four system, as follows: grade one, sessile, non-ulcerative granuloma limited to vocal process; grade two, pedunculated or ulcerated granuloma limited to vocal process; grade three, granuloma extending past vocal process but not crossing midline of airway in fully abducted position; and grade four, granuloma extending past vocal process and past the midline of the airway in the fully abducted position. The granulomas were additionally graded A if unilateral and B if bilateral. Two laryngologists and two otolaryngology residents rated the granulomas on two separate occasions. Intra- and inter-observer reliability was evaluated with the kappa (κ) test statistic.

Thirty-five vocal process granulomas were identified. The percentage intra-observer agreement for the two laryngologists was 97 and 100 per cent (κ = 0.94 and 1.00, respectively). The percentage inter-observer agreement between the two laryngologists was 91 per cent (κ = 0.83). The percentage intra-observer agreement for the two residents was 89 and 91 per cent (κ = 0.83 and 0.77, respectively). The percentage inter-observer agreement between the two residents was 83 per cent (κ = 0.67).

The proposed grading system for vocal process granuloma displayed excellent intra- and inter-observer reliability among residents and experienced laryngologists.

A variety of paediatric tracheostomy tubes are available. This article reviews those in current use at Great Ormond Street Hospital.

We outline our preferences and the particular indications for the different tubes, speaking valves and other attachments.

Practice has changed significantly in recent years. One product has been re-sized by its manufacturer; others are no longer commonly used. An updated sizing chart is included for reference purposes, together with manufacturers' contact details.

The choice of paediatric tracheostomy tube is driven by clinical requirements. A small range of tubes are suitable for the majority of children, but some will require other varieties in specific circumstances.

To determine the effect of tonsillectomy on morbidity in patients listed for tonsillectomy.

Questionnaire survey of 257 children and 159 adults who had been listed for tonsillectomy. The cohort studied had experienced delays of greater than 12 months between being listed for tonsillectomy and undergoing surgery. They had responded to an earlier questionnaire in 2003 regarding morbidity experienced while waiting for surgery. The same questionnaire was presented to them again in 2005. Morbidity experienced in 2003 was compared to that experienced in 2005 in subjects who had and had not proceeded to surgery in the interval.

Forty-seven per cent of the cohort had undergone tonsillectomy. The questionnaire response rate was 48 per cent. Respondents reported less morbidity in 2005 than in 2003, whether or not they had had surgery. Respondents who had undergone tonsillectomy reported significantly greater reductions in morbidity than those who had not. Five per cent of children who had undergone tonsillectomy experienced at least three short episodes of tonsillitis in the six months before the questionnaire, compared with 35 per cent of those who had not undergone tonsillectomy (p < 0.001).

The morbidity reported by patients suffering from chronic, untreated tonsillitis decreases with time. Tonsillectomy produces significantly greater reductions in morbidity than time alone.

We report a rare case of otophyma.

A case report of otophyma and a review of the current literature concerning otophyma and the more common rhinophyma, are presented.

A 46-year-old male presented with slow growing fleshy growths on both auricles which were excised. A diagnosis of otophyma was made. Although rosacea is more common, otophyma and other ‘phymas’ are thought to be the end stage of the rosacea spectrum of skin disease. However, unlike rhinophyma, otophyma is rarely seen and as a result there is little in the English language literature regarding it. Consequently, the management of otophyma is largely based on previous experiences with rhinophyma.

To our knowledge this is the first case report of otophyma in the otolaryngology literature and only the second described in the English language literature. This case demonstrates the difficulties faced in diagnosing this rare condition and our successful management of this case.

This paper outlines our use of cricothyroid cannulation in those patients undergoing head and neck surgery in whom a ‘difficult airway’ is anticipated. Audit results are presented.

Prospective data collection for all patients undergoing cricothyroid cannulation for management of head and neck neoplasms, over a two-year period.

Thirty-nine cricothyroid cannulae were sited in 32 patients. All patients with laryngeal tumours underwent the procedure while awake, prior to the anticipated difficult intubation, and the cannulae were removed within six hours. Most cannulations performed under general anaesthetic were for anticipated ‘dangerous extubations’ in patients with oral cavity tumours, and these cannulae remained in place for 24 hours. Tracheostomy was possibly avoided in six patients. No complications were identified.

Cricothyroid cannulation can be a simple, safe, reliable technique which is a useful adjunct in the management of patients with a potentially difficult airway.

Obstructive adenoid enlargement is commonly implicated as the major cause of chronic nasal obstruction in children. Although clinical assessment is considered essential, there is little consensus over its reliability. This study was conducted to determine the correlation between graded symptomatology assessment and roentgenographic assessment of adenoidal obstruction.

Symptoms assessed included snoring, mouth-breathing and obstructive breathing during sleep. Each symptom was rated on a four-point scale (absent = zero, mild = one, moderate = two and severe = three). We summed the ratings for each child to obtain the symptomatology score. We used an adenoidal–nasopharyngeal ratio parameter to classify roentgenographic assessment into minimal, moderate or marked obstruction.

Sixty-four children, 42 boys and 22 girls, aged one to 12 years were enrolled. The clinical symptomatology scores correlated significantly with the roentgenographic ratings of nasopharyngeal airway obstruction (r = 0.419; p = 0.001). The correlation was significant at roentgenographic ratings of minimal obstruction (p < 0.05) and gross obstruction (p < 0.001). Both the symptomatology score and the roentgenographic rating showed significant correlations with patient age (r = −0.657, p < 0.01 and r = −0.340, p < 0.01, respectively).

Clinical rating of adenoidal symptoms in children provides a reasonably reliable assessment of the presence and severity of nasopharyngeal airway obstruction. This technique of assessment is easy to use and is particularly valid when obstruction is either minimal or gross.

The aim of this study was to evaluate the outcomes of therapeutic intervention in patients with mutational falsetto, by applying perceptual and acoustic analysis before and after voice therapy.

Forty-five consecutive patients with mutational falsetto were studied retrospectively. Acoustic analysis (i.e. fundamental frequency, jitter, shimmer, and formants one, two and three) was performed using the Multi-Dimensional Voice Program. Perceptual voice analyses were performed, including graded severity–roughness–breathiness–aesthenicity–strain assessment.

Subjects' fundamental frequency, voice formants one, two and three, jitter, and shimmer were greater before than after treatment. There were statistically significant differences between pre- and post-treatment average values for fundamental frequency, jitter and shimmer. There were also statistically significant differences between pre- and post-treatment average values for formants one and two. These results were maintained after six months of follow up, and there was no significant difference between results at three- and six-month follow up. According to perceptual evaluation, each subject's voice had altered from mutational falsetto to chest voice by completion of the intervention. Thus, all of the patients successfully lowered their modal speaking voice to an appropriate level.

In the light of objective evaluations, and by applying the study treatment protocol, these results suggest that normal voice can be maintained after intervention, at six months' follow up.

We report a method of inserting a T-tube.

A 14-G branula and a T-tube are used.

This method was found to be simple and required few instruments.

To the best of our knowledge, this method has not previously been reported.

To evaluate the type of aerobic bacteria commonly isolated from peritonsillar abscesses.

A retrospective study involving 60 patients presenting with peritonsillar abscess treated between 2003 and 2006.

The patients were treated in a tertiary care, teaching hospital. The records of the patients were reviewed and analysed.

Gram-positive organisms were commonly isolated from the abscesses. However, an increasing trend towards Gram-negative bacterial isolates was noted. The antibiogram showed changing patterns of sensitivity, with a resistance to penicillin.

There is an increasing incidence of Gram-negative aerobic bacteria causing peritonsillar abscess. Appropriate antibiotics for Gram-negative bacteria should be included in the regimen if such bacteria are isolated in culture and sensitivity studies.

Empirical antibiotics with Gram-negative cover will be appropriate as adjunctive therapy.
