Retroverted epiglottis presenting as a variant of globus pharyngeus.

We describe a series of four patients who presented with 'high globus pharyngeus', who all had an abnormally curled epiglottis tip touching and indenting the tongue base. The actual incidence of 'curling epiglottis', as well as the potential impact of this variation in persistent globus symptoms, is not known. We therefore describe for the first time a series of patients with this anatomical variant of the epiglottis, each of whom experienced unresolved globus symptoms despite receiving intensive medical treatment. In the literature, the success rate for improvement in symptoms following medical treatment ranges from 68 to 80 per cent. Following CO2 laser partial epiglottectomy, all four patients experienced complete relief of their symptoms. We advocate consideration of this treatment for high globus pharyngeus that fails to respond to conservative treatment, in cases with proven curled epiglottis on endoscopic examination.

A quartet of lateral sinus thrombosis, extradural abscess, subdural abscess and occipital abscess: complications of acute mastoiditis in a pre-adolescent child.

Neurological complications of acute mastoiditis are rare but can be life threatening. Their presentation may be masked by the use of antibiotics. We present a unique case of acute otitis media progressing to occipital, extradural and subdural abscess formation and lateral sinus thrombosis in a child. The clinical course and management of a pre-adolescent male is presented and discussed. We review the incidence, presentation and treatment of occipital abscesses and lateral sinus thrombosis with acute mastoiditis. Following extended cortical mastoidectomy, neck exploration and broad spectrum intravenous antibiotics, the patient made a full recovery. This is the first reported case of acute mastoiditis associated with occipital abscess in a child. Early, aggressive treatment is required for a successful outcome. The rarity of neurological complications, in addition to the insidious onset and subtle symptoms associated with antibiotic therapy, can make diagnosis extremely difficult. Patients with acute otitis media who fail to respond fully to treatment should be referred early for a specialist otology opinion.

Foreign body sensation in the throat due to displacement of the superior cornu of the thyroid cartilage: two cases and a literature review.

The sensation of a foreign body in the throat when swallowing is a common and very discomforting symptom for those who experience it. Common causes are gastroesophageal reflux disease and possibly upper oesophageal dysmotility. This complaint may be dismissed as psychogenic when a cause for the problem is not readily apparent. We present two cases in which the patient had a foreign body sensation in the throat, associated with a dry swallow. The most helpful diagnostic procedure was careful examination of the hypopharynx and neck and flexible fibre-optic rhinolaryngoscopy. One case was treated with surgery of the neck and larynx to trim the medially projecting superior cornu of the thyroid cartilage. Surgery was successful in eliminating the symptoms. Although an uncommon finding, our experience is that symptoms due to a medially displaced thyroid cornu should be considered in the differential diagnosis as an important and surgically correctable cause of persistent foreign body sensation at the hyoid level in the neck.

Rhinological, laryngological, oropharyngeal and other head and neck side effects of drugs.

Following a previous paper in which we documented the otological side effects of drug therapy, we here review other drug side effects that ENT surgeons may encounter when dealing with patients. Although otological drug side effects such as hearing loss and tinnitus are well recognized there are many rhinological, laryngeal, oropharyngeal and other head and neck drug side effects. Our data were sourced from the British National Formulary and Electronic Medical Compendium websites.

Thyroid cancer review 3: management of medullary and undifferentiated thyroid cancer.

This is the last of the three review articles dealing with thyroid cancer. Over 90% of thyroid cancer is of the differentiated type associated with a very good 10-year disease-free survival rate. In contrast, the rare forms of thyroid cancer which comprise medullary thyroid cancer arising from parafollicluar C cells, Hurthle cell carcinoma, anaplastic carcinoma, thyroid lymphoma and squamous cell carcinoma are typically associated with a poorer survival rate. Management is based upon small retrospective cohort studies.

A blinded in-vitro study to compare the efficacy of five topical ear drops in clearing grommets blocked with thick middle ear effusion fluid.

OBJECTIVE: To compare the efficacy of 5% NaHCO3, 3% H2O2, Sofradex (dexamethasone sodium metasulphobenzoate 0.05%, framycetin sulphate 0.5%, gramicidin 0.005%), 0.33% acetic acid and 0.9% NaCl eardrops in clearing grommets blocked with harvested thick middle ear effusion fluid. STUDY DESIGN: A blinded in-vitro study. SETTING: District general hospital. PARTICIPANTS: A total of 473 grommets were blocked with freshly harvested unpooled thick middle ear effusion fluid obtained from 68 patients. MAIN OUTCOME MEASURES: Patency of the grommets before and 7 days after intervention was ascertained by tympanometry and close visual inspection. RESULTS: Instillation of eardrops leads to a statistically significant increase in the clearance of grommets as compared with not using any drops (chi2 = 14.3, d.f. = 5, P = 0.006). The numbers needed to treat were 2.8 for NaHCO3, 3.2 for 0.9% NaCl, 3.9 for 0.33% acetic Acid, 4.4 for Sofradex and 9.5 for H2O2 eardrops. Pair-wise comparison was only significant for comparison between 5% NaHCO3 and 3% H2O2 eardrops (Bonferroni corrected P = 0.01, odds ratio = 4.3, CI = 1.9-9.9). CONCLUSIONS: Use of eardrops leads to a clinically and statistically significant increase in the clearance of blocked grommets. Of the five drops used, 5% NaHCO3 was the most efficacious and 3% H2O2 the least efficacious. Limitations of this in-vitro study are recognized and a prospective in-vivo double blind randomized controlled trial is planned.

Thyroid cancer review 1: presentation and investigation of thyroid cancer.

Thyroid cancer is uncommon with an estimated lifetime risk of 0.8% for women and 0.3% for men. The incidence appears to be increasing by 4% per year and is currently the eighth commonest cancer in women. Managing thyroid cancer is challenging, as no prospective randomised trials exist. Most of the information is derived from large patient cohorts in which therapy has not been randomly assigned. This is the first of the three review papers we have written on the management of thyroid cancer.

Thyroid cancer review 2: management of differentiated thyroid cancers.

This is the second review article on thyroid cancer dealing with the common differentiated types that comprise 90% of thyroid cancers. Despite clinical management guidelines offered by a number of organisations including the British Association of Otolaryngologists and Head and Neck Surgeon, The British Thyroid Association, The American Association Of Endocrinologists, The American Thyroid Association and the National Cancer Centre Network, debate regarding the management of differentiated thyroid cancer continues. This is because of the absence of good quality research evidence as a consequence of the natural history of this disease.

Sudden sensorineural hearing loss following intracarotid injection of heroin.

A 26-year-old male presented with sudden right-sided sensorineural hearing loss after injection of heroin into the right neck. The hearing loss was found to be profound with no other associated abnormalities on examination or investigation. There was no change at 3-month follow-up. This was most probably due to arterial injection and is a previously unreported complication of heroin abuse.

Spontaneous rupture of the cervical oesophagus following nose blowing: a case report.

Spontaneous rupture of the oesophagus is a rare event. Most have been reported in association with oesophageal carcinoma, peptic ulceration and alcohol abuse followed by forceful episode of vomiting. We, however, report a case of spontaneous rupture of the oesophagus in an otherwise healthy individual with no history of alcohol intake, as a consequence of blowing of the nose.

Otologic side effects of drugs.

Otolaryngologic symptoms are common and patients presenting to the otolaryngologist will often be taking drugs for the treatment of unrelated diseases. As a doctor, one must not forget the potential of these drugs to cause otologic side effects and, in some cases, to be the cause of the presenting symptom. We performed a comprehensive search of the British National Formulary and Electronic Medical Compendium websites to classify the otologic side effects caused by drugs. Not all the data were found at both websites. We have compiled all the data together, subclassified them and produced a review of the otologic side effects of drugs, in table form.

A prospective single-blind randomized-controlled trial comparing two surgical techniques for the treatment of snoring: laser palatoplasty versus uvulectomy with punctate palatal diathermy.

The aim of this study was to compare laser palatoplasty with uvulectomy with punctate palatal diathermy as treatment modalities for snoring. The study design was a prospective, single-blind, randomized-controlled trial. Eighty-three patients entered the trial. After a mean follow-up period of more than 18 months there was no statistically significant difference between the two groups regarding the patient perception of benefit from surgery or the subjective improvement in snoring. However, there was a statistically significant difference in the degree of pain in the immediate postoperative period (mean difference = 22.14, 95% CI = 7.98-36.31, P = 0.003), with the pain being worse in the laser palatoplasty group. Relative risk of complications for laser palatoplasty was 1.42 (95% CI = 0.93-2.17). The snoring scores and Glasgow Benefit Inventory scores decreased with time in both the groups but there was no statistically significant difference between the two groups.

A blinded in vitro comparison of five sets of bipolar diathermy forceps.

The objective of this blinded randomized trial was to compare five sets of bipolar forceps, both single use and reusable, and discuss their potential role in postoperative complications. An animal tissue experiment was set up with standardized parameters. Results indicate larger tips give larger burns. We also found that some forceps gave suboptimal burns.

Why do we have a uvula?: literature review and a new theory.

From ancient times up to the present day many different functions and conditions have been attributed to the uvula, many speculative and some with a more scientific basis. The uvula has been shown to have the ability to produce and secrete large quantities of thin saliva. A common complication of surgery involving removal of the uvula is pharyngeal dryness. We have observed that on phonation and swallowing the uvula swings back and forth in the oropharynx. We present a review of the literature on the uvula and propose a theory that the uvula bastes the throat and thereby helps keep it moist and well lubricated.
