The role of ANCA in the management of cocaine-induced midline destructive lesions or ENT pseudo-granulomatosis with polyangiitis: a London multicentre case series.

OBJECTIVE: In this multicentric study involving three London hospitals, we compared ANCA-positive and ANCA-negative cocaine-induced midline destructive lesions (CIMDL) patients to assess how presence of antineutrophil cytoplasmic antibodies (ANCA) may correlate with disease severity. Our secondary aims are to better classify etiology centered around ANCA positivity and, consequently, better disease management. METHODS: A retrospective review was performed to identify patients with CIMDL seen between January 2019 and December 2022. Population data including age, sex, presentation, endoscopic findings, duration of cocaine use and active use of cocaine, type of treatment, laboratory (including ANCA serology), radiological, and histological findings were collected. RESULTS: Forty CIMDL patients (25 male, median age of 42 years) were identified. The majority of them (72.5%) presented with either a septal perforation, a saddle nose deformity (22.5%), and/or a palatal fistula (20.0%). ANCA was positive in 71.1% of cases (66.7% p-ANCA). No statistically significant differences in the general characteristics, type of treatment, laboratory results, radiological or histological findings were observed when comparing ANCA-positive and ANCA-negative CIMDL patients or when comparing p-ANCA and c-ANCA patients. Similarly, no statistically significant difference was obtained when comparing the pattern of distribution of lesions between the two groups. CONCLUSIONS: A large percentage of CIMDL patients showed positive ANCA test (71.1%) and in the majority of the cases a p-ANCA pattern specifically targeting PR3 (p-ANCA, PR3 + MPO-). However, ANCA positivity or presence of a specific ANCA pattern was not associated with more severe presentation or more aggressive disease. Given its similarities to granulomatosis with polyangiitis (GPA), we recommend the use of the term "cocaine-induced ENT pseudo-GPA" instead of CIMDL. LEVEL OF EVIDENCE: IV Laryngoscope, 2023.

Safety of day-case endoscopic sinus surgery in England: An observational study using an administrative dataset.

INTRODUCTION: As elective surgical services recover from the COVID-19 pandemic a movement towards day-case surgery may reduce waiting lists. However, evidence is needed to show that day-case surgery is safe for endoscopic sinus surgery (ESS). The aim of this study was to investigate the safety of day-case ESS in England. DESIGN: Secondary analysis of administrative data. METHODS: We extracted data from the Hospital Episodes Statistics database for the 5 years from 1 April 2014 to 31 March 2019. Patients undergoing elective ESS procedures aged ≥17 years were included. Exclusion criteria included malignant neoplasm, complex systemic disease and trans-sphenoidal pituitary surgery. The primary outcome was readmission within 30 days post-discharge. Multilevel, multivariable logistic regression modelling was used to compare outcomes for those operated on as day-cases and those with an overnight stay after adjusting for demographic, frailty, comorbidity and procedural covariates. RESULTS: Data were available for 49 223 patients operated on across 129 NHS hospital trusts. In trusts operating on more than 50 patients in the study period, rates of day-case surgery varied from 20.6% to 100%. Nationally, rates of day-case surgery increased from 64.0% in the financial year 2014/2015 to 78.7% in 2018/2019. Day-case patients had lower rates of 30-day emergency readmission (odds ratio 0.71, 95% confidence interval 0.62 to 0.81). Outcomes for patients operated on in trusts with ≥80% day-case rates compared with patients operated on in trusts with <50% rates of day-case surgery were similar. CONCLUSIONS: Our data support the view that ESS can safely be performed as day-case surgery in most cases, although it will not be suitable for all patients. There appears to be scope to increase rates of day-case ESS in some hospital trusts in England.

Litigation in Septorhinoplasty Surgery: A Pan-Specialty Review of National Health Service (the United Kingdom) Data.

Success in septorhinoplasty surgery can be difficult to assess due to a lack of objective and measurable outcomes. If patients' expectations are not met, it places surgeons performing septorhinoplasty at risk of litigation which can be stressful and costly. The National Institute of health (NHS) Resolution is a government-funded organization in the United Kingdom that provides expertise to the NHS on resolving patient concerns. Data were requested from NHS Resolution for claims involving septorhinoplasty surgery over a period of 5 years between April 2015 and April 2020. Rhinoplasty claims performed by all specialties were included. Data included the claim status, incident details, alleged injury, damages claimed, and damages paid. A total of 31 claims were identified by the study, equating to a total cost of £1,347,336.10. Of the 31 claims for rhinoplasty or septorhinoplasty, 9 cases were open (29%, £962,361.00) and 22 cases were closed (71%, £384,975.10). The common causes for claims were "intraoperative problems (32%)," "failure to warn-informed consent (19%)," and "foreign body left in situ (13%)." The most common injuries were "cosmetic disfigurement (39%)," "unnecessary pain (29%)," and "additional/ unnecessary operation (29%)." This study highlights the need for improved awareness of clinical negligence claims among surgeons who perform septorhinoplasty. Results are applicable to all specialties who perform the procedure. The study highlights the importance of assessing patients' motives and expectations prior to surgery and emphasizes the need for a well-documented rigorous consent process.

The Role of Social Media in Improving Patient Recruitment for Research Studies on Persistent Post-Infectious Olfactory Dysfunction.

Background and Objectives: Since the COVID-19 pandemic, the number of cases of post-infectious olfactory dysfunction (PIOD) has substantially increased. Despite a good recovery rate, olfactory dysfunction (OD) becomes persistent in up to 15% of cases and further research is needed to find new treatment modalities for those patients who have not improved on currently available treatments. Social media has emerged as a potential avenue for patient recruitment, but its role in recruiting patients with smell dysfunction remains unexplored. We conducted a survey using the AbScent Facebook page to evaluate the feasibility of using this platform for future studies on smell dysfunction. Materials and Methods: Between 26 October and 4 November 2021, we conducted an online survey to evaluate propensity of patients with PIOD who would be willing to participate in research studies on smell dysfunction. Results: Sixty-five subjects were surveyed with a response rate of 90.7%. The median visual analogue scale (VAS) for sense of smell was 0 at infection and 2 at survey completion. The median length of OD was 1.6 years, and the main cause of OD was SARS-CoV-2 (57.6%). Parosmia was reported in 41 subjects (69.5%) whilst phantosmia in 22 (37.3%). The median length of olfactory training (OT) was 6 months but subjectively effective in 15 subjects (25.4%). Twenty-seven subjects (45.8%) tried other medications to improve olfaction, but only 6 participants (22.2%) reported an improvement. All subjects expressed their propensity to participate in future studies with most of them (38; 64.4%) willing to be enrolled either in medical and surgical studies or to be part of a randomised study design (11; 18.6%). Conclusions: Using the AbScent Facebook platform we successfully selected a population of subjects with persistent and severe OD that have failed to improve on available treatments and are willing to participate in further clinical trials.

Olfactory dysfunction in antineutrophil cytoplasmic antibody-associated vasculitides: A review of the literature.

Olfactory dysfunction (OD) has been described in patients with antineutrophil cytoplasmic antibody-associated vasculitides (AAV), but the underlying mechanisms are not completely understood. The causes of altered smell function can generally be divided into conductive, sensorineural or others. To date no specific treatment is available for AAV-related OD and the efficacy of currently available options has not been explored. The aim of this review is to provide an overview of the causes that may lead to OD in patients with AAV. Current available treatments for OD and possible options in patients with AAV presenting with smell impairment are also mentioned.

The Evidence Base for the Benefits of Functional Septorhinoplasty and its Future Post COVID-19.

Ever since the introduction of the concept of Procedures of Limited Clinical Value (PoLCV), procedures such as functional septorhinoplasty have been subject to additional funding restrictions within the British National Health Service. Recent publications have suggested that 10% of Clinical Commissioning Groups in the United Kingdom no longer fund septorhinoplasty surgery irrespective of the indications, including congenital malformations or post-trauma, and despite the strong evidence available in the literature in treating a range of health conditions. Thus, inequity exists across the country. At present functional septorhinoplasty surgery is frequently but incorrectly grouped together with aesthetic rhinoplasty, both of which are deemed to be cosmetic interventions. Moreover, as we exit the peak of the current coronavirus disease 2019 (COVID-19) pandemic, procedures deemed to be of lower clinical priority will potentially be at risk throughout Europe. The purpose of this review is twofold; the first is to put forward the evidence to commissioners in favor of functional septorhinoplasty surgery on patient well-being and mental health; the second is to demonstrate why functional septorhinoplasty surgery is a distinct procedure from aesthetic rhinoplasty and why it ought not to be classified as a procedure of limited clinical value.

The role of surgery in antineutrophil cytoplasmic antibody-associated vasculitides affecting the nose and sinuses: A systematic review.

BACKGROUND: The ear, nose and throat region has been reported to be one of the commonest sites involved in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis diseases and often precedes the diagnosis of ANCA-associated vasculitis by many months. Although treatment for ANCA-associated vasculitis primarily requires systemic immunosuppressive therapy, there are specific indications for sinonasal surgery during the course of the disease process. The three major roles for surgery in sinonasal vasculitis are to aid diagnosis through biopsy, enable symptom relief and nasal reconstructive surgery consideration when in remission. PURPOSE: The aim of this systematic review is to provide an overview of the surgical procedures which can be performed in patients with ANCA-associated vasculitis presenting with sinonasal involvement. MATERIALS AND METHODS: A systematic literature search was performed for scientific articles on MEDLINE (PubMed Advanced MEDLINE Search) and EMBASE. The search included all articles up to April 2020. CONCLUSION: Surgical intervention during the active phase of ANCA-associated vasculitis disease can improve the patient's symptoms and enable histological diagnosis. The surgical decision to manage the nose requires a multidisciplinary approach involving the vasculitis specialist and the ear, nose and throat surgeon. Nasal reconstruction can be performed to restore form and function but only when the disease is in remission so as to maximise success and minimise complications.

Tumour resection volumes and facial nerve outcomes for vestibular schwannomas.

The objective of this study is to correlate tumour volume relationship with surgical outcomes in subtotal resections and accepted nomenclature through a retrospective study at Charing Cross Hospital, London, a tertiary referral centre. The participants were 16 patients with vestibular schwannoma managed with subtotal resection between 2002 and 2011. The main outcome measures were surgical technique; tumour volume; recurrence and post-operative facial nerve function. Mean pre-operative and post-operative volumes for all patients were 14.7 and 3.7 cm(3) respectively. Tumour volumes do not correlate with diameter (p < 0.05). Mean reduction in volume of these subtotal resections was 75 %. Long term facial nerve outcome was good in the majority of patients: House-Brackmann Grade I/II in 12 (75 %), Grade III/IV in 2 (12.5 %) and Grade V/VI in 2 patients (12.5 %). Notably, two patients with Grade I/II House-Brackmann grading later developed Grade V/VI palsy following adjunctive radiotherapy. Seven of the 16 subtotal resections had subsequent radiotherapy or microsurgery. Mean follow up was 26.5 months. In conclusion, subtotal resections lead to good facial nerve outcomes but may require further treatments. Radiation treatment can worsen facial nerve function. There is no standardised use of tumour volumes or accepted guidelines for resection terminology. We propose the use of tumour volumes to define this further.

An "Uncrimped" SMart Stapes Prosthesis: A Cause of Late Hearing Deterioration in Otosclerosis.

Statement of Problem. Stapedotomy is the treatment of choice for otosclerosis. Numerous techniques and prosthesis are available to perform this procedure. Success rates of surgery vary from 17% to 80%, and revision surgery carries an increased risk of complications as well as poorer hearing outcomes. Method of Study. Case report. Results. We report the first case of uncrimping of a SMart stapes prosthesis with no lateral displacement as a cause of late failure despite successful crimping and improvement in audiological outcomes after initial surgery. Conclusion. The SMart stapes prosthesis is widely used and has been shown to be safe and provide good hearing outcomes. Displacement of a stapes prosthesis is the commonest cause of failure. Our case shows that deterioration of hearing thresholds can occur from uncrimping of the prosthesis with no displacement. It is important to improve our understanding of stapedotomy failure as revision procedures are associated with poorer outcomes.

Impact of long-term nasopharyngeal airway on health-related quality of life of children with obstructive sleep apnea caused by syndromic craniosynostosis.

Obstructive sleep apnea in children with syndromic craniosynostosis is a well-documented entity, and airway management in these group of children is difficult, with well-documented cardiorespiratory and neurodevelopment consequences. Numerous well-documented techniques are available for airway management in this group of children. In our center, the nasopharyngeal airway (NPA) is the first-line treatment. This study aimed to evaluate the improvement in health-related quality of life in this group of children using the Glasgow Children's Benefit Inventory. We conducted a retrospective postal study of 24 patients with craniofacial disorders who had an NPA inserted as part of their airway management. A 79.2% (n = 19) response rate was obtained. Mean (SD) age was 5.8 (4.1) years. Patients were classified into 3 main groups: Crouzon (n = 11), Apert (n = 6), and Pfeiffer (n = 2) syndromes. There was improvement in 3 of the 4 domains, namely, learning (P = 0.006), vitality (P = 0.003), physical (range, -3 to 8; mean, 2; P = 0.005). There was significant improvement in the sleep study parameters; however, no correlation was found between this and the Glasgow Children's Benefit Inventory findings. Parents also preferred an NPA as opposed to a tracheostomy when given a choice. Our study shows that NPA confers significant improvement not only in health-related quality of life but also in severity of obstructive sleep apnea as judged by sleep study parameters. The NPA is also well tolerated by patients and is much preferred by parents for airway management for their children as opposed to having a tracheostomy. We think that this should be considered in other centers as first-line management in children with syndromic craniosynostosis.

Endoscopic management of an internal laryngopyocele presenting with acute airway obstruction.

Statement of Problem. Laryngocele is a rare laryngeal disease, where there is an abnormal dilatation of the saccule of the laryngeal ventricle. It can either be internal or external, and a laryngopyocele is a rare complication of this anomaly. Internal laryngopyoceles can prove difficult to manage, as they often present with airway compromise. Method of Study. Case Report. Results. We present a case of a laryngopyocele that was successfully managed with suspension laryngoscopy and endoscopic marsupialisation and resection. To our knowledge, this is the first such case described in the literature. Conclusions. Surgical drainage of a laryngopyocele via the external approach is well documented in the literature. We feel that endoscopic resection of laryngopyoceles in an emergency situation is a viable alternative and also prevents the associated surgical morbidity.

Allergic laryngitis as a cause of dysphonia: a preliminary report.

OBJECTIVES: To investigate the relationship between air-borne allergen exposure and Voice Handicap Index scores in patients seeking medical treatment for rhinitis. METHODS: As we had previously identified a higher-than-expected incidence of allergy in patients presenting to a voice clinic, we undertook a prospective audit of patients without specific voice-related complaints presenting to a rhinology clinic to see if these patients might have unrecognized vocal dysfunction. To this end 70 consecutive patients with no pre-reported voice-related symptoms presenting to a teaching hospital rhinology clinic underwent skin prick testing to common air-borne allergens and completed the Voice Handicap Index (VHI) questionnaire. Discriminant performances in the Voice Handicap Index and its individual domains and questions were determined using analysis of variance. An allergy-specific subset of the VHI was constructed and tested using receiver operating characteristic (ROC) statistics. RESULTS: There were 30 males and 40 females. Mean age was 36 ± 12 years. Dust mite (83%), house dust mite (55%), and grass pollen (40%) were the commonest allergens, and 23 patients did not react to common allergens. Mean VHI score was 23.7 ± 20.1 in patients with ≥ 4 allergens, 10.8 ± 21.3 in patients with fewer than 4 allergies, and 7.8 ± 8.5 in non-allergics (P = 0.044; analysis of variance). Nine VHI questions best discriminated between allergic and non-allergic patients (P < 0.05), and the combined VHI-9 score had a ROC area under the curve of 0.85. CONCLUSIONS: Patients with more air-borne allergies have a higher incidence of undiagnosed vocal dysfunction, as determined by the raised Voice Handicap Index score, than those with fewer or no such allergies. As noted, earlier work has shown that, conversely, patients with vocal dysfunction have a high incidence of undiagnosed allergy.

Is dysphonia due to allergic laryngitis being misdiagnosed as laryngopharyngeal reflux?

OBJECTIVES: Voice problems affect up to 30% of the population at some time during their life, and in particular it affects those who use their voice professionally. Patients who commonly present with dysphonia are often found to have symptoms of both allergy and reflux. Clinical examination of the larynx often makes it difficult to differentiate between the main causative factors of dysphonia, as the clinical findings on nasendoscopy between reflux and allergy are similar. Laryngopharyngeal reflux (LPR), an entity of gastro-oesophageal reflux, is a common diagnosis made in the voice out-patient clinic. Few studies have been able to successfully correlate management of LPR and outcome of dysphonia. Allergy or more specifically allergic rhinitis is said to affect approximately 24% of the population, but few studies have investigated its role in dysphonia. DESIGN: Prospective observational study. SETTINGS: University teaching hospital otolaryngology department. PARTICIPANTS: Fifteen new patients with primary voice disorder were investigated for possible LPR and allergy from April 2007 to October 2007. All patients were tested using the validated reflux symptom index (RSI), reflux finding score (RFS) to diagnose LPR, and both skin prick tests (SPT) and nasal nitric oxide (NO) levels to diagnose the presence of allergy. MAIN OUTCOME MEASURES: Prevalence of symptoms of reflux and allergy in patients presenting with primary voice disorders, and also whether dysphonia thought to be caused by LPR could actually be due to allergy. RESULTS: No positive correlation or statistical significance was found between reflux and allergy. From our sample 20% (three patients) were diagnosed with LPR and 67% (ten patients) with allergy. The three patients diagnosed with LPR also had concomitant allergy. CONCLUSIONS: In our patient cohort, three times as many patients demonstrated allergy compared with LPR. This has led us to question if some patients with allergic laryngitis are being misdiagnosed with LPR and thereby being over-treated with proton pump inhibitors (PPIs).

Adenotonsillectomy for sleep-disordered breathing in children with syndromic craniosynostosis.

Syndromic craniosynostosis (SCS) is known to be associated with sleep-disordered breathing (SDB) in childhood. Problems can occur at various levels, but midface hypoplasia is a major factor in affected infants.Adenotonsillectomy (AT) has been proven to be efficacious as a first-line treatment of SDB in healthy children. However, its role in the treatment of this issue in those with SCS has not been evaluated. Owing to the multiple possible levels of obstruction in such individuals, AT may have no benefit. This study therefore aimed to evaluate the effectiveness of AT in this group of patients.Twenty-six children with SCS with moderate to severe obstructive sleep apnea (OSA) were treated with AT. The mean age at surgery was 4.5 years (range, 1.6-13.9 y). Seven had severe OSA, 11 had moderate OSA, and 7 had mild OSA preoperatively. Of 25 children, 15 (60%) demonstrated an improvement in sleep severity scores postoperatively.Overall, there was a significant improvement in the mean number of saturation dips greater than 4%/h and in the mean nadir of dips in saturation after the operation. There was no significant difference in mean oxygen saturation, number of pulse rate rises per hour, or percentage time spent less than 90% SaO2.Clinically, there is thought to be some benefit in performing AT in these groups of patients. In children with SCS, in whom the cause of obstruction might be at multiple levels, AT should still to be considered as first-line treatment in the management of OSA/SDB.We acknowledge that some children may still go on to require further airway intervention. Further multicenter trials would be useful to examine more closely the significance of the effects of AT in children with craniofacial disorders experiencing SDB.

Penicillium species as a rare isolate in tracheal granulation tissue: a case series.

INTRODUCTION: Granulation tissue formation is a major problem complicating the treatment of upper airway stenosis. We present two cases of recurrent tracheal granulation tissue colonisation by Penicillium species in patients undergoing laryngotracheal reconstructive surgery for post-intubation tracheal stenosis. We believe that although most Penicillium species do not cause invasive disease they can be a contributory factor to the occurrence of upper airway stenosis. CASE PRESENTATION: A microbiological and mycological study of tracheal granulation tissue in two patients with recurrent laryngotracheal stenosis was carried out. Penicillium species was seen microscopically and cultured from tracheal granulation tissue. Neither patient grew any bacteria known to be associated with airway granulation tissue formation. Amphotericin B, itraconazole, flucytosine voriconazole and caspofungin were highly active against both isolates. CONCLUSION: A search for a fungal cause should form part of the investigation for recurrent tracheal granulation tissue during laryngotracheal reconstruction.

Role of tonsillectomy in the search for a squamous cell carcinoma from an unknown primary in the head and neck.

Cervical metastases of an unknown primary lesion accounts for 5%-10% of head and neck cancers. Tonsillar carcinoma is the third most common, with an incidence in the region of 18%-47% of unknown primaries, and the likelihood of synchronous tonsillar tumour of about 5%-10%. Current practice for investigating an unknown primary includes computed tomography (CT) with or without magnetic resonance imaging (MRI), and then, if necessary, 18-fluoro-deoxy-glucose positron emission tomography (FDG-PET). This is followed by panendoscopy with biopsy from the potential primary sites and tonsillectomy. A five-year retrospective review of our database of metastatic squamous cell carcinomas from unknown primary sites identified patients with synchronous tonsillar tumours (n=5). All had clinically normal-looking tonsils; MRI was within normal limit and a PET-CT identified the ipsilateral tonsillar primary in three cases only. Bilateral tonsillectomy rather than a tonsillar biopsy in the search for an unknown primary has been standard practice in our unit. Identification of a second primary dictates planning for the primary site and in the long term, influences patients' survival. We therefore recommend that bilateral tonsillectomy should be standard in the investigation of patients who present with cervical metastases from an unknown primary in the head and neck region.
