Coblation tonsillectomy: a double blind randomized controlled study.

Tonsillectomy has been performed by a number of techniques. This double blind randomized controlled study compares the technique of tissue coblation with bipolar dissection for the removal of tonsils in 10 adult patients with a history of chronic tonsillitis. A significant reduction in post-operative pain and more rapid healing of the tonsillar fossae were found in the side removed by tissue coblation. There were no episodes of primary or secondary haemorrhage on either side. This new technique for tonsil removal warrants further study.

Paediatric coblation tonsillectomy.

OBJECTIVE: Tonsillectomy has been described using a number of techniques. Recently Coblation Technology has been used to remove tonsils with anecdotal evidence of a reduction in post-operative morbidity. In this study we aim to see if there is any difference in post-operative pain, tonsillar fossae healing and return to a normal diet performing tonsillectomy, using tissue coblation compared with standard bipolar dissection. METHODS: A double blind randomised control trial to compare the technique of tissue coblation with standard bipolar dissection to remove tonsils in 38 children on the waiting list for tonsillectomy, with a history of chronic tonsillitis or obstructive tonsils. RESULTS: A significant reduction in post-operative pain was found in the children whose tonsils were removed by tissue coblation (P<0.0001). More rapid healing of the tonsillar fossae was found in the coblation group. Children who had their tonsils removed by coblation were found to return to their normal diet far sooner than those who underwent bipolar dissection. There were no episodes of primary or secondary haemorrhage in either group. CONCLUSIONS: This new technique using tissue coblation for tonsil removal offers significant advantages in the post-operative period, with rapid return to a normal diet and a drastic reduction in analgesic requirements following the surgery.

Blood loss reduction during laser turbinectomy.

The use of a combination of topical and injected anaesthetic and vasoconstrictive agents is widely applied in rhinological practice. To prepare the nose prior to a laser inferior turbinectomy under combined general and local anaesthetic, we routinely spray the nose with 1:1000 epinephrine and inject 2% xylocaine with 1:80.000 epinephrine into each inferior turbinate. With the current climate tending towards evidence based medicine, we were keen to show that our technique of pre-operative nasal preparation was effective. A randomised, double blind, prospective study was carried out, with patients acting as their own control. We found that the injection of 2% xylocaine with 1:80.000 epinephrine did not confer any additional benefit, in terms of blood loss or post-operative pain, in the treatment of these patients. The inferior turbinate that was injected bled more during the procedure than the non-injected side; there was no difference in post-operative discomfort between the 2 sides.

Carcinoma of the hypopharynx and cervical esophagus in young adults.

Squamous cell carcinoma of the hypopharynx and cervical esophagus usually presents in the late-middle-aged and elderly. When diagnosed in young adults, the disease process is often thought to be more aggressive and have a worse long-term outcome. Four hundred ninety patients presented to the Christie Hospital and Manchester Royal Infirmary between 1981 and 1990 with squamous cell carcinoma of the hypopharynx and cervical esophagus. Of this group, 24 patients (5%) received their diagnosis before the age of 45. A comparison is made with a control group of 156 (32%) patients who presented between the ages of 60 and 69 years. Analysis of tumor and nodal staging at presentation demonstrates no statistically significant difference between the 2 age groups. There is a higher incidence of a combination of smoking and alcohol abuse in the older age group, but it is of no statistical significance. There is no difference in 5-year survival results between the 2 groups. We conclude that patients with squamous cell carcinoma of the hypopharynx and cervical esophagus who receive their diagnosis under the age of 45 show no difference in tumor stage or long-term outcome when compared with a control group encompassing the mean age of presentation.

Auditory rehabilitation in neurofibromatosis type 2: a case for cochlear implantation.

Cochlear implantation has a limited but definite role in the rehabilitation of certain neurofibromatosis type 2 (NF2) patients. The presence of a dead ear either before, or after, tumour removal does not necessarily imply loss of function in the eighth nerve; in some instances the hearing loss will be cochlear. Promontory or round window electrical stimulation may help to identify those individuals with surviving eighth nerve function. In such patients multichannel cochlear implantation promises a better level of audition than the auditory brain stem implant. This paper highlights such a case and the management problems are discussed.

ENT open access clinic: an audit of a new service.

Ear, nose and throat emergencies constitute a heavy but unpredictable workload for the junior otolaryngologist. Patients are often seen in the treatment room on the ward or in the casualty department. Many patients referred as emergencies can in fact be seen the following day without detriment. This audit examined the change in treatment room workload when an open access ENT clinic was set up each weekday morning. The results demonstrate that around 75 per cent of the patients seen were suitable for waiting until the next day. The clinic was considered a success as it provided benefits for GP access, routine clinics, junior doctor teaching and concentration of aural toilet cases under expert nurse care.

The large vestibular aqueduct syndrome: the role of cochlear implantation in its management.

In recent years the large vestibular aqueduct syndrome has become an increasingly recognized cause of a progressive sensorineural hearing loss. Cochlear implantation, although not correcting the bony abnormality, does offer an avenue for rehabilitation for affected individuals and initial results are encouraging. Of 15 patients identified with the large vestibular aqueduct syndrome we have implanted seven (five adults and two children). All patients underwent an uneventful electrode insertion with uncomplicated postoperative periods. Three of our adult patients are showing very good initial results with BKB speech recognition scores of 100%, 74% and 66% with the implant alone. It is still early days with the children, but initial results are encouraging. A full review of the large vestibular aqueduct syndrome is given along with our results.

Petrosal cholesteatoma: management considerations for minimizing morbidity.

OBJECTIVE: This study aimed to analyze the surgical treatment of patients presenting with petrosal cholesteatoma. STUDY DESIGN: The study design was a retrospective case review. SETTING: The study was conducted at a tertiary referral center. PATIENTS: Patients were referred to the University Department of Otolaryngology, Manchester Royal Infirmary, with surgically confirmed petrosal cholesteatoma. INTERVENTION: Interventions were diagnostic and therapeutic. MAIN OUTCOME MEASURES: Postoperative facial function, hearing loss, recurrent cholesteatoma, and petrous cavity morbidity in relation to preoperative signs, intraoperative findings, and surgical techniques were measured. RESULTS: Twenty-five patients were treated between 1979 and 1997. Complete preoperative facial paralysis was always associated with bony erosion around the geniculate ganglion, and facial nerve ischemia was thought to be an important factor. Resection of the ischemic nerve segment and end-to-end anastomosis over the posterior fossa dura allowed full removal of cholesteatoma matrix and reinnervation along a healthy and vascularized nerve. In five of the seven cases with recurrent disease, cholesteatoma was localized to the intrapetrous carotid or geniculate ganglion. The introduction of endoscopic techniques has allowed assessment of the full extent of disease and removal of cholesteatoma matrix missed using conventional microscopic visualization. Bipolar diathermy to areas of cholesteatoma, densely adherent to dura, is effective in destroying squamous epithelium. Patients with cavity obliteration and blind sac closure had minimal postoperative morbidity, and current magnetic resonance imaging techniques are effective in diagnosing and delineating recurrence. CONCLUSIONS: This study illustrates a gradual change in the treatment of patients with petrosal cholesteatoma. By defining the main areas of patient morbidity and using both recent technical advances and alternative surgical techniques, further improvement in patient outcome is envisaged.

Cochlear ossification after meningitis.

OBJECTIVE: This study aimed to assess the pathologic processes that result in ossification of the cochlear lumen after bacterial meningitis. STUDY DESIGN: The study design was a retrospective case review. SETTING: The study was conducted at a tertiary referral center. PATIENTS: Profoundly deaf postmeningitic patients who underwent cochlear implantation were studied. INTERVENTIONS: Diagnostic and therapeutic observations were performed. MAIN OUTCOME MEASURES: The extent of cochlear ossification is classified and related to age at which infection occurred, cerebrospinal fluid leukocyte count, Gram's stain, organism, and delay between meningitis and implantation. The extent of ossification noted on high-definition computed tomographic (CT) scan is compared with surgical findings and related to the time delays between meningitis, imaging, and surgery. RESULTS: Ossification fell into three groups: gross ossification of the scala tympani and variable amounts of the scala vestibuli; partial ossification localized to the basal turn of the scala tympani; and no ossification. There was no correlation between the extent of ossification and the age when infected, type of pathogen, cerebrospinal fluid leukocyte count, and time delay between meningitis and implantation. Visualization of bacteria on Gram's stain was a highly sensitive measure of ossification (0.93) but was not specific (0.6) with positive and negative predictive values of 0.76 and 0.86, respectively. High-definition CT underestimated the extent of ossification in 50% of cases when performed within 6 months of meningitis. CONCLUSIONS: Ossification is either gross or localized to the basal turn of the scala tympani. If ossification does occur, it is rapid and complete within a few months of infection. The visualization of bacteria on Gram's stain is a sensitive indicator for the presence of ossification but has low specificity. High-definition CT, if performed within the first 6 months of meningitis, can be an inaccurate diagnostic tool and therefore should be performed as close to the date of surgery as possible.

General practitioner consultations after a paediatric tonsillectomy.

General Practitioner (GP) consultations were audited in paediatric patients who have undergone an elective tonsillectomy on our unit over a 6 month period. As there is no formal follow-up, it is the department's practice to discuss with the patients the problems to expect following the operation. This is reinforced with a tonsillectomy advice sheet. An initial audit of GP consultations was performed by a telephone survey of the relevant GP. This revealed an attendance rate of 41%. Following the implementation of a change in management (chewing gum was added to the post operative care instructions) a subsequent audit of 91 children was performed. A marked reduction in the GP attendance was observed. We now routinely recommend the use of chewing gum in the post-operative period after tonsillectomy to our patients.
