RESUMO
BACKGROUND: Head and neck carcinoma of unknown primary (CUP) represents a challenging diagnostic process when standard work-up fails to identify the primary tumour site. The aim of this systematic review and meta-analysis was to evaluate the diagnostic utility and complication profile of transoral robotic surgery (TORS) tongue base mucosectomy (TBM) in the management of CUP. PATIENTS AND METHODS: An electronic database search was performed in the EMBASE, MEDLINE, PubMed and Cochrane databases. A meta-analysis of proportions was performed to obtain an estimate of the overall proportion for the detection and complication rates. RESULTS: Nine studies representing 235 patients with CUP who had TORS TBM were included in the final analysis. The overall pooled tumour detection rate was 66.2% [95% confidence interval (CI) 56.1-75.8]. The incidence of tumour detection in human papilloma virus (HPV)-positive cases (81.5%, 95% CI 60.8-96.4) was significantly higher than HPV-negative cases (2.3%, 95% CI 0.00-45.7). Weighted overall complication rate was 11.4% (95% CI 7.2-16.2). The majority were grade I or II (80%) according to the Clavien-Dindo classification. CONCLUSIONS: This meta-analysis suggests TORS to be safe and effective in localising the primary tumour site in patients with CUP. While the current data supports the use of TORS in patients who are HPV positive, larger numbers of HPV-negative cases are required to determine the true diagnostic effect with TORS before any valid conclusions can be inferred in this particular subgroup. Further research should focus on high quality prospective trials with stringent methodological work-up to minimise heterogeneity and allow for more accurate statistical analysis.

BACKGROUND: Transoral Robotic Surgery (TORS) and radiotherapy are considered oncologically equivalent primary treatment options for early-stage HPV-positive oropharyngeal squamous cell carcinoma (OPSCC). Quality of Life (QoL) and Patient Reported Outcome Measures (PROMs) are therefore imperative in supporting clinical decision-making and optimising patient-centred care. The aim of this article is to evaluate how these primary treatment modalities compare in terms of QoL. MATERIALS AND METHODS: Systematic review and meta-analysis of studies comparing primary TORS and primary radiotherapy for OPSCC using validated QoL tools. Swallowing and global QoL were the primary endpoints with secondary endpoints including all other QoL domains. An inverse variance random-effects model was employed to calculate the weighted estimate of the treatment effects across trials. RESULTS: A total of six studies collectively reporting on 555 patients were included (n = 236 TORS and n = 319 radiotherapy). Meta-analysis showed no significant difference for swallowing (mean difference = -0.24, p = 0.89) and global QoL (mean difference = 4.55, p = 0.14). For the remaining QoL domains (neck/shoulder impairment, neurotoxicity, voice, xerostomia, speech, and distress), the scarcity of data did not permit meta-analysis. However, the existing data showed no significant difference for any except for xerostomia where TORS appears favourable in the sole study reporting on this. CONCLUSIONS: TORS and radiotherapy appear to be comparable primary treatment options for early stage OPSCC when it comes to QoL. However, a substantial proportion of patients in the TORS group received adjuvant (chemo)radiotherapy rendering it difficult to establish the 'true' QoL outcomes following surgery alone. There are also minimal studies reporting QoL outcomes beyond swallowing and global QoL. Further research is therefore needed, including more randomised trials adequately powered to detect differences in QoL outcomes.

OBJECTIVE: Abscess tonsillectomy is performed during an active episode of quinsy. Apprehensions regarding an elevated bleeding risk have hindered its widespread acceptance. This study aims to assess the prevalence of post-tonsillectomy bleeding (PTB) associated with abscess tonsillectomy. DATA SOURCES: A search was performed on August 27, 2023 in Medline, Embase, PubMed, Cochrane CENTRAL, and Web of Science databases. REVIEW METHODS: The systematic review was conducted in adherence to the PRISMA guidelines. Pooled PTB rate was determined using a meta-analysis of proportions. The JBI tool was used to assess the quality of the included studies. RESULTS: Of the 525 search records, 18 studies met the eligibility criteria for final analysis. These comprised of retrospective single-center analyses. The pooled prevalence of PTB was 6.65% (95% C.I. 4.01-9.81), and the return-to-theatre rate was 2.35% (95% C.I. 1.48-3.37). There was no difference in PTB rate between unilateral and bilateral tonsillectomy. However, the bipolar technique was associated with a higher PTB rate compared to cold steel dissection. The overall quality of the body of evidence was moderate. CONCLUSION: Our study highlights the complications associated with abscess tonsillectomy. These findings contribute valuable insights into this potential treatment option for quinsy. LEVEL OF EVIDENCE: N/A Laryngoscope, 2024.
RESUMO
Necrotizing otitis externa (NOE) is an aggressive and fast-evolving infection of the external auditory canal. Late diagnoses and untreated cases can lead to severe, even fatal consequences and so early diagnosis and treatment are paramount. NOE is a notoriously challenging diagnosis to make. It is therefore important to understand what diagnostic modalities are available and how otolaryngologists can use them to accurately treat such an aggressive disease. This review aims to evaluate the different diagnostic options available in NOE and discuss their advantages and limitations, thus, providing an up-to-date picture of the multimodal approach required in the diagnosis of this disease.
RESUMO
PURPOSE: It is unclear if septal deviation at the insertion points to the nasal cavity is associated with the overall septal deviation. This study aimed to assess septal deviation at the cribriform plate (CP) and maxillary crest (MC) using CT scans and to see if there was any correlation with overall septal deviation. METHODS: All consecutive CT sinus scans between January 2020 and December 2021 were retrospectively reviewed. Patients were excluded if they had a history of head, nasal or facial trauma, or any previous nasal surgical procedure. Angles between the septum and MC and the septum and CP as well as maximal angle of septal deviation (MSD) were measured. RESULTS: A total of 70 scans were included in the final analysis. The mean MSD was 8.14°. The mean septal deviation was 0.89° at the CP and 2.02° at the MC. The correlation coefficient between the deviation at the CP and MSD was 0.025 and between the deviation at the MC and MSD was 0.321. CONCLUSION: Our data reveal a positive correlation between septal deviation at the floor of the nose and overall septal deviation; this was not observed at the septal deviation at the roof. This could be explained due to the inherent tilt in the cribriform plate or by earlier ossification and fixation of the septum during its development at its insertion to the roof, thereby allowing further growth and potential for deviation of the lower part of the septum and its insertion to the floor.

Spontaneous meningoencephaloceles (MECs) are sparsely documented in the literature. Those occurring in the frontal sinus are an exceedingly rare entity. MECs are commonly associated with cerebrospinal fluid (CSF) rhinorrhoea. CSF rhinorrhoea is frequently misdiagnosed, causing delays in diagnosis and management. The subsequently increased risk of bacterial meningitis can be life-threatening to patients. We report the case of a woman in her late 70s with a spontaneous frontal sinus MEC, presenting with a 6-month history of CSF rhinorrhoea. The patient was successfully treated using the novel Carolyn's window approach endoscopically; 9-month follow-up revealed no skull-base breach. Our case emphasises the importance of considering MEC as a differential diagnosis for clear rhinorrhoea and demonstrates successful repair through a novel surgical approach.

OBJECTIVE: Idiopathic sudden sensorineural hearing loss (SSNHL) is typically treated with systematic or intratympanic corticosteroids. Current ENT-UK guidelines suggest treatment with a dose of oral prednisolone 1mg/kg/day for 7 days then tapered over a further 5 days. However, there is no consensus on the effectiveness of corticosteroids for idiopathic SSNHL and no universally accepted optimal regime. The objective of this systematic review was to examine the effect of high dose versus standard dose corticosteroids in the management of idiopathic SSNHL. METHODS: A systematic review was performed of all published data related to patients with idiopathic SSNHL who were treated acutely with high dose corticosteroid therapy. Articles were included that reported data on high dose, or comparing standard dose to high dose, oral or intravenous corticosteroid therapy for the treatment of patients with idiopathic sudden sensorineural hearing loss. Articles where patients received only combination treatment with intra-tympanic steroid were excluded. Risk of bias was assessed using the ROBINS-I tool and the ROB-2 tool. RESULTS: Six studies were included in the analysis, representing 919 patients. Two prospective single-arm studies of patients with SSNHL treated with a high dose steroid regime found mean hearing level improved (79.5dB to 42.3dB) and 45.8% of idiopathic patients had complete recovery of hearing. Three retrospective case-series comparing high dose to standard dose regimes found a significantly greater improvement in hearing level (38.3dB vs. 48.8dB, P = 0.042), a greater mean absolute hearing gain (44.4dB vs. 15.1dB) and a significantly higher rate of functionally relevant recovery (35.7% vs. 7.4%, P = 0.035) in patients treated with high dose regimes. The single included prospective randomised trial found no statistically significant difference in mean hearing level or speech discrimination score between patients treated with high dose pulse steroids or a standard dose regime. CONCLUSIONS: Our systematic review found the reported outcomes in the literature in this area to be mixed, with some studies suggesting a greater degree of hearing recovery with a high dose regime but others suggesting no difference. The overall quality of the available evidence was deemed to be low, with the studies at moderate risk of bias.

OBJECTIVES: Vestibular schwannoma (VS) is a tumor of the vestibulocochlear nerve. Current literature indicates that 1.6% of patients undergoing magnetic resonance imaging of the internal auditory meatus (MRI IAM) for audiovestibular symptoms are diagnosed with a VS. However, there is limited research reporting on patients who present with unilateral tinnitus without asymmetrical hearing loss. This study is a systematic review and meta-analysis evaluating how many of those patients had a VS diagnosed on MRI IAM. DATABASES USED: Online searches of PubMed, Medline, and Embase databases were performed up to October 2022. METHODS: This meta-analysis was undertaken aligning with PRISMA guidelines. Articles reporting on patients having MRI IAM for unilateral tinnitus without asymmetrical hearing loss were included. Outcomes measures were patient demographics, VS cases, incidental findings, size, and management of tumor. A meta-analysis of proportions was performed using a random-effects model with the restricted maximum likelihood method. Quality assessment was performed using the Joanna Briggs Institute critical appraisal checklist. RESULTS: Seven case series were included in the review: a total of 1,394 patients. Seven patients had a VS, with a median size of 4 mm. The pooled detection rate for VS was 0.08% (95% confidence interval = 0.00-0.45). Subsequent management was reported in six cases of which four were actively monitored and two surgically excised. The most common incidental finding was sinus disease (49 patients). CONCLUSION: Our findings indicate that MRI IAM has a low diagnostic yield for VS detection in patients presenting with unilateral tinnitus without asymmetrical hearing loss, with mostly small tumors that are conservatively managed.

OBJECTIVE: Bell's palsy is typically treated with oral corticosteroids (40-60 mg daily). Concomitant antivirals are currently not recommended. The objective of this systematic review and meta-analysis was to examine the effect of high-dose versus standard-dose corticosteroids, without antivirals, in the management of Bell's palsy. DATABASES REVIEWED: Embase, MEDLINE, PubMed, CINAHL, Cochrane Library. METHODS: A systematic review and meta-analysis was performed according to PRISMA guidelines. Studies comparing high-dose (≥80 mg) or standard-dose (40-60 mg) corticosteroid therapy for Bell's palsy were included. Exclusion criteria were coexisting antiviral treatment, nonoral drug delivery, and facial palsy due to other causes. Risk of bias was assessed using ROBINS-I. A weighted estimate of treatment effects across trials as odds ratios (OR) using a Mantel-Haenzel random-effects model was calculated. RESULTS: Three articles were included in the analysis, representing 485 patients. There was a significant decrease in nonrecovery with high-dose, compared with standard-dose, corticosteroids at 6 months follow-up (OR = 0.17, 95% confidence interval = 0.05-0.56, p = 0.004). Overall adverse events were 5.8% (n = 28), all reported in one study in the high-dose group (transient elevated liver enzymes and fecal occult blood). CONCLUSIONS: Our analysis shows a favorable effect of high-dose corticosteroid in the treatment of Bell's palsy. It is the first to evaluate this effect without the use of antivirals in keeping with current treatment recommendations. As all included studies had a serious risk of bias, future research should focus on larger trials with more robust methodology. This will allow for more up-to-date and large-scale analyses where more valid conclusions can be drawn that may potentially influence treatment protocols.

BACKGROUND: Spontaneous cerebrospinal fluid (CSF) leaks (SCSFL) occur in the absence of trauma, surgery, or underlying intracranial pathology. They represent a significant healthcare burden on patients with complications such as meningitis. We present our experience of SCSFL repair via the endonasal endoscopic approach. METHODS: All patients who underwent CSF fistula repair at a tertiary UK hospital, between 1st January 2012 to 31st December 2019, were identified and had their case notes analyzed retrospectively. RESULTS: There were 33 patients included consisting of 27 (81.8%) females, with age range from 31 to 81 years (mean 55.2). Mean body mass index (BMI) was 35.2 kg/m2 , with 32 (97.0%) patients overweight (BMI >25). All patients presented with intermittent watery rhinorrhoea and had a positive biochemical analysis. Computed tomography (CT) and/or magnetic resonance imaging (MRI) identified leak sites in 29 patients (87.9%). The most common intraoperative defect site was the cribriform plate (42.4%). A variety of closing techniques were used including onlay grafts (72.7%), tissue glue (87.9%), nasoseptal flaps (63.6%), mucosal free grafts (21.2%), fat grafts (21.2%), and additional support materials (87.9%). Nasal packing was used in all patients. The average length of stay was 1.6 days. Postoperative complications occurred in two patients (6.1%) (meningitis, epistaxis). Overall, there was a successful primary repair in 32 (97.0%) patients with most cases employing a multilayered reconstruction method (78.8%). CONCLUSION: Our results demonstrate excellent success rates with the endoscopic endonasal approach to SCSFL. This adds to the literature by demonstrating a detailed analysis of the experience in SCSFL management in one of the largest UK centres.

Social media is increasingly used for large-scale population predictions, such as estimating community health statistics. However, social media users are not typically a representative sample of the intended population - a "selection bias". Within the social sciences, such a bias is typically addressed with restratification techniques, where observations are reweighted according to how under- or over-sampled their socio-demographic groups are. Yet, restratifaction is rarely evaluated for improving prediction. In this two-part study, we first evaluate standard, "out-of-the-box" restratification techniques, finding they provide no improvement and often even degraded prediction accuracies across four tasks of esimating U.S. county population health statistics from Twitter. The core reasons for degraded performance seem to be tied to their reliance on either sparse or shrunken estimates of each population's socio-demographics. In the second part of our study, we develop and evaluate Robust Poststratification, which consists of three methods to address these problems: (1) estimator redistribution to account for shrinking, as well as (2) adaptive binning and (3) informed smoothing to handle sparse socio-demographic estimates. We show that each of these methods leads to significant improvement in prediction accuracies over the standard restratification approaches. Taken together, Robust Poststratification enables state-of-the-art prediction accuracies, yielding a 53.0% increase in variance explained (R 2) in the case of surveyed life satisfaction, and a 17.8% average increase across all tasks.
RESUMO
The most commonly reported superior thyroid cornu (STC) anatomical variation is in STC syndrome, where the cornu is enlarged or medially displaced. STC agenesis is a rare laryngeal variation that can be unilateral or bilateral. Previous studies have reported STC agenesis in cadaveric or forensic studies in patients with an otherwise normal larynx. We report a case of unilateral STC agenesis in the context of a stage III glottic laryngeal squamous cell carcinoma. The variation was discovered intra-operatively during a total laryngectomy and was clinically unknown beforehand. There were no clinical or histological signs of bony erosion by the tumor. To our knowledge, this is the first report of unilateral STC agenesis in a patient with laryngeal malignancy. This article draws attention to a rare anatomical variant of the larynx and highlights the surgical implications including potential diagnostic challenges and operative considerations.
RESUMO
Thyroid mucoepidermoid carcinoma (MEC) is a rare thyroid malignancy first documented in 1977. The majority of thyroid MECs are indolent, low-grade tumours with excellent prognosis. A woman in her 60s presented with an ongoing sensation of a lump in the left neck. There were no swallowing, voice or airway concerns. Ultrasound of the neck showed an enlarged thyroid with U5 and U3 features on the right and left lobes, respectively. Right fine needle aspiration cytology (FNAC) demonstrated certain features of Hurthle cell or anaplastic carcinoma (Thy5). Left FNAC showed Hurthle cell changes with atypical cells and prominent nucleoli (Thy3a). Following total thyroidectomy, histopathology revealed synchronous right low-grade MEC and left papillary thyroid microcarcinomas (pT2(m) N0 M0) on a background of Hashimoto's thyroiditis. This case adds to the literature and details the key histopathological features for a rare but important differential in patients with thyroid carcinoma due to synchronous histological types.

Background: Despite the completion of 5 or 6 years of undergraduate study, the transition to a newly qualified foundation year 1 doctor (FY1) in the UK has been recognised as challenging. We created a specific FY1 Induction Programme and aimed to evaluate its effectiveness on perceived confidence and preparedness for newly qualified doctors by assessing their responses to surveys before and after the delivery of the course. Methods: Pre- and post-course surveys were administered at the start and end of the course, respectively. All questions were subjective and used a 5-point Likert scale (1, not at all confident, to 5, definitely confident) to assess perceived confidence in a range of questions before and after the course. Results: A total of 35 participants completed the pre-course survey and 41 completed the post-course survey. For all questions, there was a statistically significant increase in confidence ratings. All 41 participants completing the post-course questionnaire responded 'yes' to feeling more confident to be an FY1 after completing the programme compared to before (100%). Conclusions: Our study, along with previously published work, has shown a repeatable positive effect with implementation of transition courses for newly qualified doctors. Future research in this area could focus on more large-scale standardised learning events incorporated by different trusts prior to commencement as an FY1, to see if the positive effects found in our study are translatable across other regions.

RESUMO
Background: Transoral Robotic Surgery (TORS) has been increasingly employed in head and neck surgery for the assessment and treatment of malignancies over the last two decades. PuraBond® is a self-assembling viscous solution that forms a transparent hydrogel 3-D matrix to promote local haemostasis. This study aimed to assess the utility of PuraBond® in patients undergoing TORS for Human Papilloma Virus (HPV) positive oropharyngeal squamous cell carcinoma (OPSCC). Methods: All patients who underwent TORS with PuraBond® between October 2021-May 2022 at a single tertiary university hospital in the United Kingdom were included. Primary outcome measures included post-operative haemorrhage rate (primary; within 24hrs of surgery, secondary; 1-30 days post-surgery). Secondary outcome measures included, Length Of hospital Stay (LOS), swallowing complications, hospital re-admission, and surgeon-reported ease of PuraBond® application. Results: Twelve patients were included (13 procedures due to one second look and re-resection case). No patients developed primary or secondary post-operative haemorrhage. There were no re-attendances within 30 days. Average LOS was 2.78 days (range: 1.54-4.31 days). No patient required feeding tube insertion or tracheostomy. In all procedures, the use of PuraBond® was reported as 'easy'. Conclusion: This is the first study to evaluate the role of PuraBond® in TORS. The wide range of favourable outcomes reported support its safety and efficacy. The current findings mandate the need for larger, prospective, controlled studies to better define whether the known haemostatic and regenerative properties of PuraBond® may translate into direct patient benefit in the expanding field of TORS for HPV-mediated OPSCC.
RESUMO
Study design: Retrospective cohort study. Objective: Management of nasal fractures is usually in ENT emergency clinics, with our center aiming to assess patients within 10-days. During 2020, there have been numerous lockdowns and social distancing measures implemented in the UK as a result of the coronavirus pandemic (COVID). This study aimed to assess the effect of COVID on nasal fracture management in ENT emergency clinics in terms of number of patients seen, time to follow up and their management strategies. Methods: All patients with suspected or confirmed nasal bone fractures presenting to the emergency department (ED) between January 1, 2019 and December 31, 2020 at our major trauma center were analyzed in 2 groups depending on the year they were seen (2019 vs. 2020). Results: There was a total of 104 patients analyzed, with 51.4% decrease in the number of patients seen in 2020 versus 2019. The mean days to follow up in 2019 was 8.09 days and 7.65 days in 2020 (P = .37). There was no statistically significant difference in the number of patients seen within the 10-day target between years (2019 = 65.7% vs. 2020 = 76.5%, P = .35). The majority of patients were managed with manipulation under anesthesia (MUA) in 2019 (n = 32, 45.7%) vs. discharge from clinic in 2020 (n = 21, 61.8%). Conclusions: Our study shows a drastic reduction in the number of patients seen in ENT emergency clinic from 2019 to 2020. This is in-keeping with other studies that have shown a reduction in ED attendances, trauma admissions and admissions across other specialties all around the world.
RESUMO
BACKGROUND: Effective management of cerebrospinal fluid (CSF) leaks can reduce significant associated morbidity. Intrathecal fluorescein (IF) may be a valuable intra-operative adjunct to localise leak sites. Recent reports have demonstrated low doses of IF to be safe, however, no internationally accepted dose of IF has been agreed. OBJECTIVE: To assess the efficacy and safety of IF used in the endoscopic management of anterior skull base CSF fistulae. METHODS: A systematic review and descriptive analysis were performed of all published data in accordance to PRISMA guidelines. RESULTS: There were 18 included articles giving a total of 335 procedures where IF was used. Doses of IF ranged from 10mg - 150mg. IF positively identified the site of CSF fistula in 88.7% of cases (n = 297). There was a total of 25 reported peri-operative complications in all included studies (7.5%) with 5.1% (n = 17) potentially related to IF use. Of these, the complication rate was 3.9% at low IF doses (<50mg) and 80.0% at higher doses (≥50mg). CONCLUSION: Our review demonstrates that IF is effective at localising CSF fistulae with most significant complications being related to doses ≥50mg. We therefore propose that there is a potential for the licensing of IF in this field. Doses <50mg have consistently been shown to be safe while still maintaining effective localisation rates. Based on the most common doses used in this group, we recommend utilisation of a dosing below 50mg, with the most frequent range being between 10-30mg.

Medical treatment options for patients with rhinitis during pregnancy need careful considerations. It is important to distinguish between the causes of rhinitis, as this can influence treatment. Conservative options are important for patients with pregnancy-induced rhinitis (PIR) and pre-existing allergic or non-allergic rhinitis. Education and knowledge that PIR symptoms will resolve after pregnancy can offer some relief. Other strategies such as exercise, positioning, saline nasal douching/lavage, and nasal valve dilators are safe in pregnancy and can have a benefit in these patients with rhinitis of any aetiology. The main medical therapies usually used in rhinitis cannot always be directly translated to pregnant patients due to potential teratogenic effects. Topical corticosteroids have generally shown to be safe with budesonide having the strongest recommendations. Oral corticosteroids are mostly used in moderate-severe disease and should be avoided in the first trimester. Oral decongestants have associations with cardiac, ear, gut and limb abnormalities and are not recommended in the first trimester. Loratadine and cetirizine have been the most well-studied second-generation antihistamines and are generally considered safe. There has been no reported increased risk of teratogenicity with anticholinergics or cromones, with the latter being one of the first line options in pregnant women with allergic rhinitis. The role of allergen immunotherapy needs further research, but current guidance states it can be continued if already initiated prior to pregnancy. The management of rhinitis in pregnancy can therefore be complex. This review aims to evaluate the current medical management options for rhinitis in pregnancy.
