RESUMEN
OBJECTIVE: In primary parotid gland malignancies, the incidence of level-specific cervical lymph node metastasis in clinically node-positive necks remains unclear. This study aimed to determine the incidence of level-specific cervical node metastasis in clinically node-negative (cN0) and node-positive (cN+) patients who presented with primary parotid malignancies. DATA SOURCES: Electronic databases (MEDLINE, EMBASE, PubMed, Cochrane). REVIEW METHODS: Random-effects meta-analysis was used to calculate pooled estimate incidence of level-specific nodal metastasis for parotid malignancies with 95% confidence intervals (CIs). Subgroup analyses of cN0 and cN+ were performed. RESULTS: Thirteen publications consisting of 818 patients were included. The overall incidence of cervical nodal involvement in all neck dissections was 47% (95% CI, 31%-63%). Among those who were cN+, the incidence of nodal positivity was 89% (95% CI, 75%-98%). Those who were cN0 had an incidence of 32% (95% CI, 14%-53%). In cN+ patients, the incidence of nodal metastasis was high at all levels (level I 33%, level II 73%, level III 48%, level IV 39%, and level V 37%). In cN0 patients, the incidence of nodal metastasis was highest at levels II (28%) and III (11%). CONCLUSION: For primary parotid malignancies, the incidence of occult metastases was 32% compared to 89% in a clinically positive neck. It is recommended that individuals with a primary parotid malignancy requiring elective treatment of the neck have a selective neck dissection which involves levels II to III, with the inclusion of level IV based on clinical judgment. Those undergoing a therapeutic neck dissection should undergo a comprehensive neck dissection (levels I-V).

INTRODUCTION: De-escalated treatment of hemithyroidectomy without radioactive iodine (RAI) is now accepted for patients with low-risk, well-differentiated thyroid cancer (WDTC). The benefit of long-term follow-up care remains controversial. This study aims to describe parameters associated with less than total thyroidectomy, and discharge from specialist follow-up in patients with low-risk WDTC in Australia. METHODS: An online survey was distributed to Australian members of Endocrine Society of Australia, Australian and New Zealand Endocrine Surgeons, and Australian Society of Otolaryngology, Head and Neck Surgery. Clinicians completed a survey of management and follow-up care preferences for four clinical vignettes (all low-risk WDTC). RESULTS: 119 clinicians (48% endocrinologists, 55% male) answered at least one question. The majority (59%) of respondents recommended less than total thyroidectomy and omission of RAI in patients with WDTC <2 cm. Most (62%) would discharge a patient with micropapillary thyroid cancer within 1 year following total thyroidectomy. In contrast, for WDTC 1-4 cm, >90% of clinicians would continue specialist follow-up for at least 5 years. The majority of clinicians felt that patients experienced disproportionate fear of recurrence and were reassured by follow-up. After multivariable analysis, clinicians who participated in multidisciplinary teams (MDTs) were more likely to choose de-escalated care for both initial treatment (p = .005) and follow-up care (>5 years, p = .05). CONCLUSION: Clinician attitudes captured by this survey reflect recent changes in guidelines towards hemithyroidectomy for low-risk WDTC, particularly amongst MDT attendees. There is a need to further examine the impact of de-escalated care on fear of recurrence and quality of life in thyroid cancer survivors.

The purpose of this study was to determine the relationship of early and delayed tracheostomy decannulation protocols on the length of stay, time to oral feeding and incidence of postoperative complications in patients undergoing microvascular reconstruction for oral cancer. A review of all patients who underwent surgical management of oral squamous cell carcinoma (OSCC) over the study period from 01/07/2017 to 31/06/2021 was performed. Patients who underwent elective tracheostomy as part of their microvascular reconstruction were included. Two cohorts were identified based on distinct postoperative tracheostomy decannulation protocols; early (Within 7 days) and delayed (≥7 days). Time to oral feeding, length of stay and complication rates was determined for both groups for statistical analysis. A total of 103 patients with OSCC were included in the study. The overall complication rate was 35.9% and were more likely in node positive patients (53.7% vs 23.2%; p = 0.003) and in cases where the geniohyoid muscle complex was disrupted during tumour resection (66.7% vs 31.9%; p = 0.026). Early decannulation was significantly associated with shorter length of hospital stay (10 days vs 15 days) and earlier removal of nasogastric feeding tubes (7 vs 10 days). There was no difference in the overall complication rate between the two groups (33.3% vs 37.5%; p = 0.833). Early decannulation in appropriately selected patients is recommended as it significantly reduces the length of hospital stay and aids in early resumption of oral intake. Furthermore, this approach is not associated with increased rates of complications.

Abstract Introduction After pleomorphic adenoma, Warthin tumor gets its popularity as the second most common benign neoplasm of the parotid gland. Fine-needle aspiration cytology (FNAC) is the most cost-effective and minimally-invasive way to determine the histological character of a parotid gland tumor. Objective To determine the accuracy of FNAC in the diagnosis of Warthin Tumour. Methods A retrospective study conducted between 2014 and 2018. Out of 243 FNACs performed for parotid lesions, a histopathological correlation was established in 74 cases to reveal the accuracy of FNAC in the diagnosis of Warthin tumor. Results A total of 243 FNACs of parotid lesions were performed, and a histopathological correlation was established in 74 (30.4%) cases. Later on, we confirmed that 16 (21.6%) out of these 74 patients had cases of Warthin tumor. In total, 15 (20.3%) out of those 74 cases were confirmed as Warthin tumors on the initial cytology, which revealed a true positive concordance between the cytology and the final histological diagnosis; 55/74 (74%) were true negative results; on the other hand, 1/74 (1.4%) was a false negative, and 3/74 (4.1%) were false positive results. The sensitivity of the FNAC in the diagnosis of Warthin tumor was of 93%, while the specificity was of 94.8%, and the accuracy, of 94.6%. Conclusion In the present study, FNAC had a high diagnostic accuracy, reaching 94%.

RESUMEN
OBJECTIVES: Coins are the commonest foreign body ingested in paediatric populations. Although most ingested coins are either spontaneously passed or retrieved with medical intervention without serious consequence, there is potential for serious morbidity and mortality related to paediatric coin ingestion. We performed a 10-year retrospective review of Australian denomination coin ingestion at a tertiary paediatric hospital in Sydney, Australia. We attempted to determine whether a relationship exists between coin size, patient age, coin ingestion and spontaneous passage. METHODS: Hospital records of all children presenting in a 10-year period to a paediatric tertiary care centre for coin ingestion were reviewed. Demographic information, coin denomination, previous history, symptoms, investigations, management, outcome and complications were recorded. RESULTS: 241 cases were identified. The majority (55%) of cases occurred in children ≤3 years of age (range 7 months-11 years, mean 3.39 years). The most common location where coins were identified was in the proximal third of the oesophagus or at the cricopharyngeus (65%). Spontaneous passage occurred in 84 cases (34.9%) while 167 cases (69.3%) required intervention. Children ≤3 years were more likely to ingest small coins (<22â¯mm) (OR: 2.44; 1.39-4.17) and children >3 years were more likely to ingest larger coins (22-26â¯mm) (OR: 2.17; 1.39-4.35). CONCLUSIONS: Coin size, coin weight and age of the child appear to be predictors for both likelihood of ingestion and spontaneous passage in paediatric coin ingestion cases. A child with minimal symptoms, witnessed ingestion and radiographic identification of the coin in the lower oesophagus or more distal can often be safety observed for up to 24â¯h in anticipation of spontaneous passage.

PURPOSE: The study was designed to assess the difference in microbiological colonisation and growth that may occur in drains, in the setting of clean-contaminated compared to clean head and neck surgery. METHODS: A prospective observational cohort study was performed. Surgical drain tips upon removal were sent for bacterial culture and the culture results were compared between clean-contaminated and clean procedures using mixed effects logistic regression. In all statistical analyses, a priori, p < 0.05 (two-tailed) was calculated to indicate statistical significance. RESULTS: One hundred and ten drains were examined in both clean-contaminated and clean procedures. Drains from clean-contaminated procedures had a significantly longer time in situ (11 vs 5 days, p < 0.001). Overall, significant evidence was seen for an association between procedure type and drain growth rates: 68% of clean-contaminated procedures; and 45% of clean procedures. Although not statistically significant, there was an increase in normal skin flora contaminated drains in clean-contaminated procedures (41 vs 25%). Rates of pathogenic skin organisms (15 vs 16%) and pathogenic oropharyngeal organisms (2.9 vs 0%) were similar for clean-contaminated vs clean procedure patients. CONCLUSION: This preliminary study demonstrated a higher rate of microbial contamination of neck drains that were placed during procedures that involved continuity with the upper aero-digestive tract and neck. Retrograde migration of skin flora along the drain is common but of no clinical significance. Similar rates of pathogenic microbial growth have been demonstrated thus far. However, selection of nosocomial pathogens due to extended antibiotic prophylaxis may pose a risk for infection. LEVEL OF EVIDENCE: 1b.

Differentiated thyroid cancer (DTC) accounts for over 90 % of thyroid malignancies, and is frequently associated with central neck compartment nodal metastasis that requires a therapeutic central compartment neck dissection (CCND) for clinically evident nodes. Current knowledge on the expected lymph node yield from a CCND is limited, compared with data on the lateral neck. The aim of our study was to accurately quantify nodal yield from the cadaveric central neck compartment. Twenty-eight cadaveric necks were dissected and the central neck compartment was subdivided into four regions: pre-laryngeal (delphian), pre-tracheal, right and left para-tracheal regions. Each cadaver had a thyroid gland, which was also removed, and the CCND tissue in each compartment was processed and examined by a consultant histopathologist. Only lymphoid tissue with a defined microscopic fibrous capsule and subcapsular sinus was included in the node count. The median total lymph node count per cadaver was four (range 1-16), with a median of one node detectable in each para-tracheal region (range 0-7) and the pre-tracheal region (range 0-8). The median pre-laryngeal node count was 0 (range 0- 2). The average lymph node size across all compartments was 2.9 mm. This is the first European study to assess cadaveric central neck lymph nodes and establish baseline counts for nodal yield. If a prophylactic or therapeutic CCND is required during thyroid surgery, those involved in DTC management must recognise that there is a wide range, and low median yield of central neck compartment lymph nodes.

BACKGROUND: Published randomized controlled trials (RCTs) on the efficacy of intranasal corticosteroid (INCS) in chronic rhinosinusitis (CRS) use either nasal delivery (nasal drop or nasal spray) or sinus delivery (sinus catheter or sinus irrigation) in patients with or without sinus surgery. This influences topical drug delivery and distribution. The effect of these factors on the published results of RCTs is assessed. This systematic review explores the strength of evidence supporting the influence of sinus surgery and delivery methods on the effectiveness of topical steroids in studies for CRS with meta-analyses. METHODS: A systematic review was conducted of RCTs comparing INCS with either placebo or no intervention for treating CRS. Data were extracted for meta-analysis and subgroup analyses by sinus surgery status and topical delivery methods. RESULTS: Forty-eight studies (3961 patients) met the inclusion criteria. INCS improved overall symptoms (standardized mean difference [SMD], -0.49; p < 0.00001) and the proportion of responders (risk ratio [RR], 0.59; p < 0.00001) compared with placebo. It decreased nasal polyp size with a greater proportion of responders (RR, 0.48; p < 0.00001) and prevented polyp recurrence (RR, 0.59; p = 0.0004) compared with placebo. Reduction of polyp size was greater in patients with sinus surgery (RR, 0.31; 95% confidence interval [CI], 0.20, 0.48) than those without (RR, 0.61; 95% CI, 0.46, 0.81; p = 0.009). Greater symptom improvement occurred when sinus delivery methods (SMD, -1.32; 95% CI, -2.26, -0.38) were compared with nasal delivery methods (SMD, -0.38; 95% CI, -0.55, -0.22; p < 0.00001). CONCLUSION: INCS is effective for CRS. Prior sinus surgery and direct sinus delivery enhance the effectiveness of INCS in CRS.

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) represents inflammatory changes throughout the nose and sinuses from a group of disorders which all lead to swelling and overgrowth of the nasal mucosa. Topical corticosteroids have been the most widely used treatment, with each clinician using different regimes, at different doses, in different settings and with or without sinus surgery. CRSwNP requires ongoing medical management to prevent recurrence. OBJECTIVES: To assess the effects of topical corticosteroids on CRSwNP and to analyse various subgroups, including patients who had sinus surgery immediately prior to the delivery of the corticosteroids, surgery any time prior to the topical corticosteroids or patients who had never had previous surgery. Also to assess the most effective dose and delivery methods for topical corticosteroids. SEARCH METHODS: We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the search was 10 April 2012. SELECTION CRITERIA: Randomised controlled trials studying topical corticosteroids for patients with CRSwNP. DATA COLLECTION AND ANALYSIS: At least two authors reviewed the search results and selected trials meeting the eligibility criteria, obtaining full texts and contacting authors. We documented our justification for the exclusion of studies. At least two authors extracted data using a pre-determined, standardised data form. MAIN RESULTS: Forty studies (3624 patients) met the inclusion criteria. The trials were at low (21 trials), medium (13 trials) and high (six trials) risk of bias. The primary outcomes were sino-nasal symptoms, polyp size and polyp recurrence after surgery. When compared to placebo, topical corticosteroids improved overall symptom scores (standardised mean difference (SMD) -0.46; 95% confidence interval (CI) -0.65 to -0.27, P < 0.00001; seven trials, n = 445) and had a higher proportion of patients whose symptoms improved (responders) (risk ratio (RR) 1.71; 95% CI 1.29 to 2.26, P = 0.0002; four trials, n = 234). Topical corticosteroids also decreased the polyp score (SMD -0.73; 95% CI -1.00 to -0.46, P < 0.00001; three trials, n = 237) and had a greater proportion of patients with a reduction in polyp size (responders) (RR 2.09; 95% CI 1.65 to 2.64, P < 0.00001; eight trials, n = 785) when compared to placebo. Topical corticosteroids also prevented polyp recurrence after surgery (RR 0.59; 95% CI 0.45 to 0.79, P = 0.0004; six trials, n = 437). Subgroup analyses by sinus surgery status revealed a greater benefit in reduction of polyp score when topical steroid was administered any time after sinus surgery (SMD -1.19; 95% CI -1.54 to -0.83) compared to patients who had never had surgery (SMD -0.13; 95% CI -0.53 to 0.28, P < 0.00001). There was no difference between groups in terms of adverse events. AUTHORS' CONCLUSIONS: Topical corticosteroids are a beneficial treatment for CRSwNP and the adverse effects are minor, with benefits outweighing the risks. They improve symptoms, reduce polyp size and prevent polyp recurrence after surgery. Patients having sinus surgery may have a greater response to topical corticosteroids but further research is required.

BACKGROUND: Recurrent respiratory papillomatosis (RRP) causes serious morbidity. RRP in Australia may be eliminated in the near future following the implementation of a national vaccination program using a human papillomavirus (HPV) vaccine that protects against infection with HPV types 6 and 11, those responsible for RRP. Baseline data on RRP prevalence and disease burden in Australia are lacking. METHODS: Three study methods were used to estimate the burden of juvenile onset RRP in Australia. We conducted a retrospective chart review of RRP cases treated at The Children's Hospital at Westmead over 10 years, examined the coding of these cases, and then calculated and applied the positive predictive value of the codes to national data to estimate the prevalence of RRP in Australia. We also conducted an online survey of otolaryngologists in Australia who manage RRP. RESULTS: Nineteen patients were treated at the hospital over 10 years, involving 359 admissions. We estimate that between 33 and 56 RRP cases aged <20 are being treated nationally per year (0.6-1.1 per 100 000 persons), with children 5-9 years having a higher estimated rate of 1.2-1.8 per 100 000. Among 39 otolaryngologists treating juvenile onset RRP, the majority (73%) treated RRP in a paediatric tertiary hospital, and used the microdebrider for ablation of lesions. CONCLUSIONS: Our estimates of RRP disease burden agree with international estimates. As a small number of clinicians treat RRP nationally, we believe that establishment of a national RRP register is both feasible and necessary to monitor the impact of vaccination.

Steroids are increasingly being used to treat a wide spectrum of otolaryngological disorders. It is important for ear-nose-throat surgeons to understand the short- and long-term complications associated with steroid use. The aim of this study was to review the role of steroids in common ear-nose-throat disorders. Corticosteroid therapy has been shown to be effective in the management of idiopathic facial nerve palsy, allergic rhinitis, acute sinusitis, sinonasal inflammatory polyposis, and croup. The therapeutic efficacy of steroids in the management of Meniere's disease, sudden idiopathic sensorineural HL, chronic otitis media, and vestibular neuronitis remain controversial.

Selection for surgical training in Australia is currently based on assessment of a structured curriculum vitae, referral reports from selected clinicians and an interview. The formal assessment of laparoscopic psychomotor skill and ability to attain skills is not currently a prerequisite for selection. The aim of this study was to assess the innate psychomotor skills of interns and also to compare interns with an interest in pursuing a surgical career to interns with those with no interest in pursuing a surgical career. Twenty-two interns were given the opportunity to carry out tasks on the Minimal Invasive Surgical Trainer, Virtual Reality (Mentice, Gothenburg, Sweden) Simulator. The candidates were required to complete six tasks, repeated six times each. Scores for each task were calculated objectively by the simulator software. Demographic data were similar between the two groups. Although some candidates who were interested in pursuing a surgical career performed poorly on the simulator, there was no significant difference when comparing the two groups. The Minimal Invasive Surgical Trainer, Virtual Reality (Mentice) Simulator provides an objective and comparable assessment of laparoscopic psychomotor skills. We can conclude that interns have varying inherent ability as judged by the simulator and this does not seem to have an influence on their career selection. There was no significant difference in the scores between the two groups. Interns with and without inherent abilities have aspirations to pursue surgical careers and their aptitude does not seem to influence this decision. Surgical colleges could use psychomotor ability assessments to recruit candidates to pursue a career in surgery. Trainees needing closer monitoring and additional training could be identified early and guided to achieve competency.
