Frontal sinus stenting in endoscopic sinus surgery: the 10-year Oxford experience.

BACKGROUND: Frontal sinus stents have been introduced to reduce frontal sinus re-stenosis after surgery and to improve outcomes. METHOD: This study was a retrospective analysis of 19 patients who had endoscopic sinus surgery with approach to the frontal sinus and insertion of a soft sinus stent. RESULTS: The frontal recess was patent in 78.9 per cent and stenosed in 21.1 per cent of patients; no completely closed recesses were observed. Mean follow up was 20.7 months, and time period of stenting was 9.8 months on average; complications were observed in 47.4 per cent of the patients, with post-operative sinonasal infection being the most common. CONCLUSION: In the authors' experience, indications for frontal sinus stenting include recalcitrant chronic rhinosinusitis after multiple functional endoscopic sinus surgeries (especially in chronic rhinosinusitis with nasal polyps), patients with history of important craniofacial surgery or trauma, and recurrent mucoceles. The stent was overall well tolerated as only minor complications were observed. Close clinical follow up is mandatory.

A surgical protocol for sinogenic brain abscess: the Oxford experience and a review of the literature.

BACKGROUND: Rhinosinusitis-induced brain abscesses are rare but can result in devastating long-term sequalae and mortality; they require a high index of suspicion with early imaging to start early empiric parenteral antibiotic treatment covering aerobes and anaerobes. METHODOLOGY: Our study was a retrospective analysis on 32 patients who were treated at Oxford University Hospitals for rhinosinusitis-induced brain abscess between February 2013 and June 2020. RESULTS: Mean age of presentation was 45.83 for adults and 11.14 for children. Subdural collection was the most frequent abscess but 25% of patients had multiple sites of collection; the majority were in the frontal lobe. The most commonly identified pathogens were Streptococcus milleri group and Staphylococcus aureus; 93.75% of the patients were treated with combined Ceftriaxone and Metronidazole for an average of 8 weeks. CONCLUSIONS: In our series most patients received also a prompt and aggressive surgical treatment with combined neurosurgical and ENT procedures in the majority; this was especially important in case of subdural empyema, Streptococcus milleri infection and direct intracranial spread of infection. More than half of the patients were treated with a single surgical procedure. Despite aggressive treatment, one third of patients experienced long-term neurological sequelae; there were no deaths.

Characteristics, management and outcome of a large necrotising otitis externa case series: need for standardised case definition.

BACKGROUND: Necrotising otitis externa is a severe ear infection for which there are no established diagnostic or treatment guidelines. METHOD: This study described clinical characteristics, management and outcomes for patients managed as necrotising otitis externa cases at a UK tertiary referral centre. RESULTS: A total of 58 (63 per cent) patients were classified as definite necrotising otitis externa cases, 31 (34 per cent) as probable cases and 3 (3 per cent) as possible cases. Median duration of intravenous and oral antimicrobial therapy was 6.0 weeks (0.49-44.9 weeks). Six per cent of patients relapsed a median of 16.4 weeks (interquartile range, 23-121) after stopping antimicrobials. Twenty-eight per cent of cases had complex disease. These patients were older (p = 0.042), had a longer duration of symptoms prior to imaging (p < 0.0001) and higher C-reactive protein at diagnosis (p = 0.005). Despite longer courses of intravenous antimicrobials (23 vs 14 days; p = 0.032), complex cases were more likely to relapse (p = 0.016). CONCLUSION: A standardised case-definition of necrotising otitis externa is needed to optimise diagnosis, management and research.

The use of modified Montgomery T-tubes as frontal sinus stents: how I do it.

BACKGROUND: Frontal sinus surgery is challenging as the frontal recess is prone to re-stenosis and there is subsequent occlusion of the frontal sinus outflow tract. In an attempt to maintain the frontal recess calibre and reduce frontal sinus re-stenosis, frontal sinus stents have been used with different materials and varying results. OBJECTIVE: This paper presents the technique of using a modified Montgomery T-tube as a frontal sinus stent. RESULTS AND CONCLUSION: The use of a soft, self-retaining and non-absorbable stent that can be used for stenting of the frontal sinus is described. Our technique is safe, effective, inexpensive and well tolerated.

Recurrent epistaxis: predicting risk of 30-day readmission, derivation and validation of RHINO-ooze score.

BACKGROUND: To derive and validate a predictive scoring tool (RHINO-ooze score) with good sensitivity and specificity in identifying patients with epistaxis at high risk of 30 day readmission and to enable risk stratification for possible definitive intervention. METHODS: Using medical databases, we searched for factors influencing recurrent epistaxis. The information ascertained together with our analysis of retrospective data on patients admitted with epistaxis between October 2013 and September 2014, was used as the derivation cohort to develop the predictive scoring model (RHINO-ooze score). The tool was validated by performing statistical analysis on the validation cohort of patients admitted with epistaxis between October 2014 and October 2015. Multiple linear regressions with backwards elimination was used to derive the predictive model. The area under the curve (AUC), sensitivity and specificity were calculated. RESULTS: 834 admissions were encountered within the study period. Using the derivative cohort (n= 302) the RHINO-ooze score with a maximum score of 8 from five variables (Recent admission, Haemorrhage point unidentified, Increasing age over 70, posterior Nasal packing, Oral anticoagulant) was developed. The RHINO-ooze score had a chi-square value of 99.72 with a significance level of smaller than 0.0001 and hence an overall good model fit. Comparison between the derivative and validation groups revealed similar rates of 30-day readmission between the cohorts. The sensitivity and specificity of predicting 30-day readmission in high risk patients with recurrent epistaxis (RHINO-ooze score equal/larger than 6) was 81% and 84%, respectively. CONCLUSIONS: The RHINO-ooze scoring tool demonstrates good specificity and sensitivity in predicting the risk of 30 day readmission in patients with epistaxis and can be used as an adjunct to clinical decision making with regards to timing of operative intervention in order to reduce readmission rates.

Immunoglobulin G4 related chronic sclerosing sialadenitis.

BACKGROUND: ENT surgeons may be the first specialists to encounter and diagnose patients with salivary gland disease. A new entity involving the salivary glands has recently been described of which ENT surgeons need to be aware: immunoglobulin G4 related chronic sclerosing sialadenitis. METHOD: A literature search of Medline, Embase and Cochrane Library databases was performed, using the search terms 'IgG4', 'hyperIgG4 syndrome' and 'IgG4 related chronic sclerosing sialadenitis'. RESULTS: Knowledge concerning immunoglobulin G4 related chronic sclerosing sialadenitis is rapidly increasing. This new entity is part of a fibro-inflammatory corticosteroid-responsive systemic disease (immunoglobulin G4 related disease) and has been described in almost every organ. Biopsy of the submandibular gland can be diagnostic. However, the diagnosis can easily be overlooked if: clinical suspicion is not high, one is unaware of the classical morphology and/or immunoglobulin G4 staining is not performed. This paper presents a summary of the current understanding of the disease and its management. CONCLUSION: ENT surgeons should be aware of this new disease entity. Patients with systemic disease should be managed under a multidisciplinary team, with input from clinicians who have an interest in such diseases (such as gastroenterologists and rheumatologists), and input from histopathologists and radiologists.

Complications of long-term ventilation tubes.

OBJECTIVE: To demonstrate that ventilation tubes can remain in situ much longer than expected, and that the materials used in the manufacturing of these tubes can degrade and cause complications. Long-term follow up and replacement of the tube is recommended. METHOD: Case report and review of the literature concerning the use of long-term ventilation tubes. RESULTS: In the case reported, the ventilation tube was in place for 19 years, which resulted in chronic ear discharge. When it was removed, it was noted that the tube itself had degraded and had caused a chronic inflammatory reaction. CONCLUSION: We recommend that the long-term use of ventilation tubes is followed up and that the tube is replaced before material degradation takes place.

Prospective, randomised controlled trial comparing intense endoscopic cleaning versus minimal intervention in the early post-operative period following functional endoscopic sinus surgery.

OBJECTIVE: There is currently no standardised management protocol following functional endoscopic sinus surgery. This study assessed frequent endoscopic cleaning versus minimal intervention in the early post-operative period following such surgery. STUDY DESIGN: Prospective, randomised controlled, single-blinded, within-subject trial involving 24 patients with bilateral chronic rhinosinusitis undergoing bilateral functional endoscopic sinus surgery. MAIN OUTCOME MEASURE: The primary outcome measure was ethmoid cavity healing, based on endoscopic appearance, graded using a modified Lund-MacKay endoscopic score. SECONDARY OUTCOME MEASURE: Lund-MacKay symptom score before and after surgery. RESULTS: There was no overall statistically significant difference between the two groups (p = 0.37). Subgroup analysis revealed a significant effect of regular suction clearance on adhesions at three months (p = 0.048), but not on oedema, polyps, granulation, discharge or crusting. CONCLUSION: There is no evidence from this study to support frequent endoscopic cleaning in the early post-operative period after functional endoscopic sinus surgery. Less intensive post-operative management is recommended, resulting in decreased patient morbidity and fewer post-operative follow-up appointments.

Cognitive behavioural therapy for tinnitus.

BACKGROUND: Tinnitus is an auditory perception that can be described as the experience of sound, in the ear or in the head, in the absence of external acoustic stimulation (not usually audible to anyone else). At present no specific therapy for tinnitus is acknowledged to be satisfactory in all patients. Cognitive behavioural therapy (CBT) uses relaxation, cognitive restructuring of the thoughts and exposure to exacerbating situations in order to promote habituation and may benefit tinnitus patients, as may the treatment of associated psychological conditions. OBJECTIVES: To assess whether cognitive behavioural therapy is effective in the management of patients suffering from tinnitus. SEARCH STRATEGY: Our search included the Cochrane ENT Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2006), MEDLINE and EMBASE. The last search date was June 2006. SELECTION CRITERIA: Randomised controlled trials in which patients with unilateral or bilateral tinnitus as main symptom received cognitive behavioural treatment. DATA COLLECTION AND ANALYSIS: One review author (PMD) assessed every report identified by the search strategy. The four review authors assessed the methodological quality, applied inclusion/exclusion criteria and extracted data. MAIN RESULTS: Six trials comprising 285 participants were included. 1. PRIMARY OUTCOME: subjective tinnitus loudness. CBT compared to a waiting list control group: we found no significant difference (Standardised Mean Difference (SMD) 0.06 (95% CI -0.25 to 0.37)). CBT compared to another intervention (Yoga, Education, Minimal Contact - Education and Education): we found no significant difference (SMD 0.1 (95% CI -0.22 to 0.42)).2. SECONDARY OUTCOMES: a) Depression. CBT compared to a waiting list control group: we found no significant difference in either group (SMD 0.29 (95%CI -0.04 to 0.63)). CBT compared to another intervention (Yoga, Education and Minimal Contact - Education): we found no significant difference (SMD 0.01 (95% CI -0.43 to 0.45)). b) Quality of life: CBT compared to a waiting list control group: we found a significant difference in favour of CBT versus the waiting list group (SMD 0.7 (95% CI 0.33 to 1.08)). CBT compared to another intervention (Education, Minimal Contact - Education and Education): we also found a significant difference between CBT and the other intervention control group (SMD 0.64 (95% CI 0.29 to 1.00)). There were no adverse/side effects reported in any trial. AUTHORS' CONCLUSIONS: We did not find a significant difference in the subjective loudness of tinnitus, or in the associated depression. However we found a significant improvement in the quality of life (decrease of global tinnitus severity) of the participants, thus suggesting that cognitive behavioural therapy has an effect on the qualitative aspects of tinnitus and contributes positively to the management of tinnitus.

Evaluation of quality of life and psychiatric morbidity in patients with malignant tumours of the skull base.

In general, patients with malignant tumours of the skull base have a poor prognosis. Treatment may have a disfiguring physical and disabling mental effect on patients. To evaluate the effect of treatment on physical and mental quality of life in patients with skull base malignancy, we conducted a cross-sectional patient survey of 18 patients treated for such tumours, using the University of Washington (version 4) quality of life questionnaire and the hospital anxiety and depression scale. The total quality of life score (median value) was 980 (550-1125). Patients with anterior skull base malignancy scored lower than those with lateral skull base malignancy (p=0.003). In general, the worst individual domain scores were: mood (64 per cent); activity (69 per cent); and, specifically for patients with anterior skull base malignancy, taste (54 per cent, p=0.004) and anxiety (60 per cent, p=0.034). One-third of skull base cancer patients were at risk of suffering from mental distress and psychiatric morbidity (indicated as a score of more than seven on the hospital anxiety and depression scale).

Mucosal tear in the oropharynx leading to pneumopericardium and pneumomediastinum: an unusual complication of blunt trauma to the face and neck.

Pneumomediastinum and pneumopericardium are very rare complications resulting from blunt trauma to the head and neck. We report the case of a 40-year-old male who had been assaulted. He presented to the Emergency Department with bruises to the face and neck and complained of dysphagia. He was found to have extensive subcutaneous emphysema of the face and neck. Imaging revealed the presence of a mucosal tear in the oropharynx leading to pneumomediastinum and pneumopericardium. He was managed conservatively and made an uneventful recovery. This is a very rare but potentially life-threatening complication of blunt trauma to the head and neck. It poses diagnostic difficulties and treatment dilemmas, which are discussed.

Day-case septoplasty and unexpected re-admissions at a dedicated day-case unit: a 4-year audit.

INTRODUCTION: Septal surgery has been identified as suitable for day-surgery, but is not widely performed as such. Guidelines for day-surgery state that the unexpected admission rate should be 2-3%. Previous audits have not achieved this figure and septoplasty is not universally considered suitable for day-surgery. We have reviewed practice over 4 years in our institution to identify surgical and patient factors associated with unexpected admission following septoplasty. PATIENTS AND METHODS: A retrospective case note based audit of day-case septoplasty procedures reviewed at the end of each year between October 1998 and October 2002. RESULTS: A total of 432 septal surgery procedures were performed, comprising 378 septoplasties and 54 submucous resections. Thirty-eight patients were admitted, overwhelmingly because of haemorrhage in the immediate postoperative period, giving an overall admission rate of 8.8% within the first 24 h. Factors associated strongly with re-admission were the use of intranasal splints, the performance of revision surgery, submucous resection (as opposed to septoplasty) and, less so, the performance of additional procedures and the peri-operative administration of diclofenac. There was no correlation between unexpected admission and grade of surgeon, surgical technique or any of the patient factors analysed. CONCLUSIONS: The unexpected admission rate of septal surgery performed at our unit is above that recommended for day-case procedures, but is within the range previously published. Patient satisfaction with day-case septoplasty has been shown to be high. We believe that septoplasty should be performed in this setting but there is a significant chance that patients may need admission, and a pathway should be in place for this to occur with minimal disruption to the patient.

Artificial ear: A training tool for grommet insertion and manual dexterity.

Under European Working Time Directives, surgical trainees now have to attempt to gain adequate operative experience within newly-restricted working hours. Surgical skills training must therefore increasingly occur outside theatre and away from real patients, in a simulated environment. In ENT, we suggest that instruction and practice of grommet insertion may be greatly facilitated through the use of an artificial ear model, which can be assembled cheaply and quickly. Our 'ear' may also be used for manual dexterity exercises, which have the potential to be developed into validated tests of core ENT surgical skills in the future.

Mucous membrane pemphigoid: nasal and laryngeal manifestations.

Mucous membrane pemphigoid (MMP) is a sub-epithelial blistering disease that primarily involves mucosal surfaces but may also involve the skin. Clinically, it appears as vesiculobullous lesions of the oral cavity and eyes, but other tissues such as the nasopharyngeal and laryngeal mucosa can also be affected. Ultimately, scarring and airway stenosis may occur. The condition should be managed by a multidisciplinary team led by a dermatologist. Immunosuppressive therapy forms the mainstay of treatment, with surgery having both a diagnostic role and a use in the treatment of complications such as airway obstruction. There must be a low threshold of suspicion for laryngeal involvement in this group of patients, so that prompt action can be taken. Once laryngeal stenosis has occurred repeated endoscopic laser excision of scar tissue can be used to maintain an adequate airway. Adjuvant use of mitomycin-C can be used beneficially in the treatment of laryngeal complications of MMP.

External auditory canal pH in chronic otitis externa.

Several risk factors have been postulated to play a part in the progression of acute into chronic otitis externa, including changes towards alkalinity of the skin pH of the external auditory canal. These changes have been previously reported to occur in the acute stage, and their persistence may predispose to a chronic status of this condition. This prospective control study was designed to look at this possible relationship in more depth, by comparing the external auditory canal pH of individuals with chronic otitis externa, but with no current exacerbation, with an age-/sex-matched control group. Analysis of the data revealed a significantly higher external auditory canal pH in the chronic otitis externa group (P < 0.004) when compared with the controls, with no concomitant difference in body skin pH. Within this chronic otitis externa cohort, a statistically significant correlation was found between external auditory canal pH and the severity of the condition, as assessed using a multiparameter scoring system (r = 0.562; P < 0.02). Importantly, the pH was not related to the length of time since the last exacerbation. There was a significant age relationship present within our sample. Younger patients displayed more severe chronic otitis externa(r = -0.813; P < 0.001), with correspondingly higher external auditory canal pH values (r = -0.550; P < 0.02). The results suggest that alkaline ear canal skin is a local risk factor for the progression into chronic otitis externa, occurring, in this study, with greater severity in younger individuals.

Meningioma in the internal auditory canal.

A case is presented of an entirely intracanalicular meningioma in a 48-year-old woman that was excised via a conventional translabyrinthine approach to the internal auditory canal (IAC). Pre-operative magnetic resonance imaging (MRI) suggested that the tumour was a vestibular schwannoma (VS). Histological examination confirmed the intra-operative impression that the tumour was a meningioma. Although VS is by far the commonest intracanalicular tumour, the differential diagnosis includes meningioma. MRI is unable to distinguish between these two entities when the tumour is located entirely in the internal auditory canal.
