Extended cervical approach for retrosternal multinodular goiter.

Objective: Partial or total sternotomy is required for 10% of retrosternal goiter. This study reviewed our experience with an extended cervicotomic approach as an alternative surgical solution for retrosternal goiter. Methods: A retrospective study was performed on patients who underwent partial or total thyroidectomy for retrosternal goiter between 2014 and 2019 at a tertiary medical centre. Data on clinical, radiologic, and pathologic factors were analysed. Peri- and postoperative outcomes were compared between extended and standard cervical approaches to predict the need for an extended cervical approach. Results: The cohort included 265 patients, of whom 245 (92.4%) were treated by standard thyroidectomy. In 17 (6.4%), the standard approach proved insufficient, and the horizontal incision was extended to a T-shape to improve access. The remaining 3 patients required a sternotomy. Use of the extended cervical approach was significantly associated with clinical features such as male gender, diabetes, high body mass index and postoperative hypocalcaemia. Conclusions: The extended cervicotomic approach is an alternative surgical solution for retrosternal goiter, with no increased risk of significant post-operative complications.

Management of first branchial anomalies in children: 20 years of experience.

PURPOSE: Branchial cleft anomalies (BCAs) are common pediatric head and neck lesions; however, only 1-4% involve the first branchial cleft. The rare occurrence of first BCAs, their presentation at a young age, and the possible facial nerve involvement make diagnosis and treatment challenging. METHODS: A retrospective chart review was conducted for children diagnosed with their first BCA between 2000 and 2020. Data on demographics, presenting symptoms, physical findings, imaging features, previous surgery, and treatment outcomes were collected and analyzed. RESULTS: The cohort included 17 patients with a median age of 5 years at presentation. Seven (41%) had undergone previous surgical intervention before definitive surgery. Eight were classified as Work Type II anomalies, and nine as Work Type I. Sixteen patients (94%) underwent definitive surgical excision at a median age of 6.9. A parotid approach was used in 10 (62%), with dissection of the mass from the facial nerve, and a retro-auricular or end-aural approach was used in 6 (38%). Complete excision was achieved in 14/16 patients (88%). Three patients had transient facial nerve paresis postoperatively. Recurrence was noted in 3/16 patients (18%). Enhancement in imaging was positively correlated with post-operative complications (R = 0.463, P = 0.018). CONCLUSIONS: First, BCA poses a diagnostic and surgical challenge; thus, definitive surgical treatment is often delayed. The surgical approach should be tailored to the type of anomaly (Work type I or II) and possible facial nerve involvement. Risk factors for post-operative complications are a history of recurrent infections and previous surgical interventions. The presence of contrast enhancement in preoperative imaging should alert surgeons to perioperative challenges and the risk of post-operative complications.

The Clinical Behavior and Recurrence Patterns of Oral Cavity Cancer in Oral Lichen Planus Patients.

OBJECTIVES: Oral lichen planus (OLP) is a chronic inflammatory disorder involving epithelia with squamous differentiation. Although described as a potential malignant precursor, the characteristics of malignancies arising among these patients are not widely described. Our goal was to describe the patterns of disease recurrence of patients with oral cavity squamous cell carcinoma (OSCC) arising on the background of OLP. METHODS: A retrospective analysis of all surgically treated patients with OSCC at a university-affiliated tertiary care center between 2000 and 2020. RESULTS: Two hundred seventy-nine patients with OSCC treated surgically were included. Forty (14.3%) had OLP. The mean age of patients with OLP was 70.9 years compared with 64.3 years for non-OLP patients (p = 0.03). OLP patients had a significantly higher rate of disease recurrence, persistence, or multiple primary disease (70% vs. 33.9%, p < 0.001). The mean number of sequential oncologic events for each patient with recurrence was also significantly higher among OLP patients (1.86 vs. 1.36, p = 0.03), a difference explained by a higher rate of multiple primary presentations (0.71 vs. 0.28, p = 0.008). A significant difference in disease-free survival (DFS) was demonstrated between the groups as patients with OLP had a lower 5-year DFS (34.7% vs. 61.3%, log-rank p value <0.001). On multivariate analysis, OLP was significantly associated with multiple primary events (p < 0.001, Odds ratio = 7.42, 95% confidence interval 2.9-19). CONCLUSIONS: OSCC patients with OLP background demand close clinical follow-up, as multiple primary disease is significantly more common and the DFS is significantly lower among these patients. A thorough clinical evaluation for all oral cavity subsites is mandatory. LEVEL OF EVIDENCE: 3 Laryngoscope, 2024.

Prognostic Significance of Regional Disease in Young Patients with Oral Cancer: A Comparative Study.

BACKGROUND: Regional metastases are considered the most important prognostic factor in OSCC patients. We aimed to investigate the impact of regional disease among different age groups with OSCC. METHODS: A retrospective comparison between patients 40 years old or younger, 41-69 years old, and 70 years or older treated for OSCC between 2000 and 2020 in a tertiary-care center. RESULTS: 279 patients were included. The mean age was 65 ± 17.7 and 133 were male (47.7%). Thirty-six (12.9%) were 40 years old or younger, 101 (36.2%) were 41-69 years and 142 (50.9%) were 70 years or older. Five-year overall survival and disease-specific survival (DSS) were significantly better among patients younger than 40 compared to the mid-age group and patients 70 years or older (76.7% vs. 69.4% vs.48.2%, Log-rank p < 0.001, and 76.7% vs. 75.3% vs. 46.5%, Log-rank p < 0.001, respectively). While an association between regional spread and overall survival and DSS was demonstrated among all age groups, the odds ratio (OR) for death of any cause and death of disease regarding cervical metastasis was much higher among patients younger than 40 compared with the 41-69 and 70+ age groups (death of any cause-OR = 23, p-value = 0.008, OR = 2.6, p-value = 0.026, OR = 2.4, p-value = 0.13, respectively. Death of disease-OR = 23, p-value = 0.008, OR = 2.3, p-value = 0.082, OR = 4.1, p-value = 0.001, respectively). In univariate  analysis, regional metastasis was associated with disease-free survival only among patients younger than 40 (p-value = 0.04). CONCLUSIONS: Regional metastases correspond with worse prognosis in young patients compared to older patients. These patients may benefit from a comprehensive treatment approach with close post-treatment follow-up. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:2212-2220, 2024.

Salivary Gland Secretory Carcinoma; Review of 13 Years World-Wide Experience and Meta-Analysis.

OBJECTIVES: Secretory Carcinoma is a malignant salivary gland tumor, initially described in 2010. This rare tumor is associated with the translocation t(12;15) (p13;q25), resulting in the fusion gene ETV6-NTRK3. Since this tumor is quite rare, most publications describe only small cohorts of patients. We aimed to investigate the clinical, pathological, and prognostic features of this newly defined malignant entity. DATA SOURCES: Pubmed, Google Scholar, and Web of Science databases. REVIEW METHODS: All published articles between 2010 and 2023 were reviewed. Search terms included the terms "Mammary Analogue Secretory Carcinoma" and "Secretory Carcinoma". All articles published in English reporting on Secretory Carcinoma of salivary glands were retrieved. RESULTS: One-hundred and 12 retrospective articles reporting a total of 674 patients were included, with 52% males and a mean age of 44.9 ± 18.9. The event rate for patients with advanced-stage disease (Stage 3/4) at presentation was 24.1% (95% CI 17.6%-31.9%, I2 = 9.2%), 14.6% for regional metastases (95% CI 10.5%-20%, I2 = 12%), and the event rate of distant metastasis was 8.4% (95% CI 5.5%-12.7%, I2 = 4.2%). Adjuvant radiotherapy was administered for 30.3% of patients (95% CI 24.1%-37.2%, I2 = 21.5%). The recurrence rate was 19% (95% CI 15.1%-23.8%, I2 = 5%). Survival outcomes showed a 17.2% death of disease rate for Secretory Carcinoma patients (95% CI 13.5%-21.8%, I2 = 7.3%). CONCLUSIONS: Secretory Carcinoma is a rare and relatively newly defined entity arising in the parotid gland most commonly. Characterized as a low-grade tumor, the majority of patients are diagnosed at an early stage, without regional or distant disease, and the prognosis is relatively good.

Foregoing elective neck dissection for elderly patients with oral cavity squamous cell carcinoma.

OBJECTIVE: Elective neck dissection (END) improves outcomes among clinically node-negative patients with oral cavity squamous cell carcinoma (OCSCC). However, END is of questionable value, considering the potentially higher comorbidities and operative risks in elderly patients. METHODS: A retrospective review of all patients older than 65 years of age who were treated for OCSCC at a tertiary care centre between 2005 and 2020 was conducted. RESULTS: Fifty-three patients underwent primary tumour resection alone, and 71 had simultaneous END. Most primary tumours were located on the mobile tongue. The patients who did not undergo END had a higher mean age (81.2 vs. 75.1 years, P < 0.00001), significantly shorter surgeries, and shorter hospitalizations. Occult cervical metastases were found in 24% of the patients who underwent END. The two groups showed no significant differences in overall survival or recurrence rates. Similar results were shown in a subpopulation analysis of patients older than 75 years. CONCLUSION: Foregoing END in elderly patients with no clinical evidence of neck metastases did not result in lower survival rates or higher recurrence rates.

The Value of Computed Tomography in Recurrent Laryngeal Cancer Following Organ Preservation Therapy.

AIM: This study aims to assess the accuracy of computed tomography (CT) in detecting recurrent laryngeal tumors after failed chemoradiation therapy (CRT). BACKGROUND: Local recurrence of laryngeal tumors following CRT has been reported in approximately 25%, yet it is often difficult to detect. METHODS: Ten patients with laryngeal cancer who failed CRT and subsequently underwent salvage total laryngectomy were included. The laryngeal subsites involved in the tumor were identified based on postoperative pathology. The corresponding preoperative CT scans were selected for review by seven experts (head-and-neck surgeons or radiologists) who scored the extent of tumor spread on each scan on a 5-point scale, from no tumor detected to clearly visible tumor. RESULTS: The rates of high tumor detectability (scores 4-5) varied according to laryngeal subsite, from 75% in the glottic region, to 45% in the subglottic region, and to 19% in the supraglottic region (P=0.01). The detectability rates were higher on scans performed 2 years or more after CRT. CONCLUSION: The CT evaluation of laryngeal cancer after CRT has limited value, particularly in the epiglottis and subglottis.

The Predictors of Persistent Posttracheostomy Tracheocutaneous Fistula and Successful Surgical Closure.

OBJECTIVE: Persistent tracheocutaneous fistula is a well-described complication of prolonged tracheostomy, with a prevalence of about 70% when decannulation is performed after more than 16 weeks. Predictors of its occurrence and outcome of treatment in adults remain unclear. The aim of the study was to describe our experience with the treatment of persistent posttracheostomy tracheocutaneous fistula in adults and to investigate factors associated with its formation and with the success of surgical closure. STUDY DESIGN: Retrospective cohort. SETTING: Tertiary medical center. METHODS: Patients who underwent open-approach tracheostomy between 2000 and 2020 were identified by database review. Data on background, need for surgical closure, and the surgical outcome was collected from the medical files and analyzed statistically between groups. RESULTS: Of 516 patients identified, 127 with sufficient long-term follow-up data were included in the study. Compared to patients whose fistula closed spontaneously (n = 85), patients who required surgical closure (n = 42) had significantly higher rates of smoking, laryngeal or thyroid malignancy, and airway obstruction as the indication for tracheostomy, on both univariate and multivariate analysis. In a comparison of patients with successful (n = 29) or failed (n = 11) surgical closure, factors significantly associated with failure were prior radiotherapy and lower preoperative albumin level, on univariate analysis. CONCLUSION: Smoking, thyroid or laryngeal malignancy, and airway obstruction indication are risk factors for persistent posttracheostomy tracheocutaneous fistula. Patients should be closely followed after tracheostomy and referred for surgery if the fistula fails to close. Before surgery, careful evaluation of the patient's nutritional status and consideration of prior radiation treatment is mandatory.

Cutaneous Squamous Cell Carcinoma in Immunocompromised Patients-A Comparison between Different Immunomodulating Conditions.

BACKGROUND: Immunosuppression is strongly associated with an increased risk of developing cutaneous squamous cell carcinoma (cSCC). Studies on solid organ transplant recipients (SOTR) and chronic lymphocytic leukemia (CLL) patients have already demonstrated higher rates of aggressive cSCC tumors in these populations compared to immunocompetent controls. Studies on other immunosuppressed patient groups are scarce. This study was aimed at assessing the effects of different immunomodulating conditions on patients diagnosed with cSCC. We sought to compare the clinical features, treatments, and survival rates among the different study groups, as well as outcomes to those of immunocompetent controls with cSCC. METHODS: A retrospective analysis of 465 cSCC patients, both immunosuppressed (IS) and immunocompetent controls. Etiologies for immunosuppression included SOTR, CLL, chronic kidney disease (CKD), psoriasis, rheumatoid arthritis (RA) and systemic lupus erythematous (SLE). RESULTS: Compared to the control group, IS patients demonstrated several significant differences. These include higher rates of positive resection margins, higher recurrence rates, and multiple SCC tumors. Patients in the IS group, who were also given immunomodulating agents, demonstrated even lower survival rates. Cox regression analysis demonstrated statistically significant decreased overall survival (OS) rates for IS patients compared to the controls (OR = 1.9, p = 0.031). SOTR patients tend to have multiple cSCC tumors (35%), with the highest number of primary tumors compared to controls (2.54 tumors per patient on average, p < 0.001), but also compared to all other IS groups. The average SCC lesion size in the SOTR group was the smallest, measuring at 13.5 mm, compared to the control group and all other IS groups. Decreased survival rates were seen on Cox regression analysis compared to controls (HR = 2.4, p = 0.001), but also to all other IS groups. CLL patients also had the highest rates of positive margins compared to controls (36% vs. 9%, p < 0.01) and to all other IS groups. They were also most likely to get adjuvant or definitive oncological treatments, either radiotherapy or chemotherapy, compared to controls (36% vs. 15%, p = 0.02) and to other IS groups. Patients in the CKD group demonstrated the highest rates for multiple cSCC (OR = 4.7, p = 0.001) and the worst rates of survival on Cox regression analysis (HR = 3.2, p = 0.001). Both rheumatoid arthritis and psoriasis patients demonstrated the shortest disease-free survival rates (2.9y ± 1.1, 2.3y ± 0.7, respectively), compared to controls (4.1y ± 2.8) and to all other IS groups. CONCLUSIONS: Among cSCC patients, immunosuppression due to SOTR, CLL, CKD, RA, and psoriasis is associated with worse outcomes compared to controls and other IS groups. These patients should be regarded as high-risk for developing aggressive cSCC tumors. This study is the first to assess and compare cSCC outcomes among multiple IS patient groups.

Ultrasonographic Features of Salivary Glands after Radioiodine Therapy in Patients with Thyroid Cancer.

OBJECTIVE: Chronic sialadenitis is the most common complication of radioactive iodine (RAI) treatment. The aim of the study was to ascertain sonographic features of the major salivary glands in patients with papillary thyroid cancer (PTC) treated with RAI. METHODS: The database of a tertiary medical center was retrospectively searched for consecutive patients who underwent total thyroidectomy for PTC in 2011-2020 with ultrasound follow-up after 1 year. Changes in ultrasound features of the major salivary glands were compared between patients treated or not treated with RAI postoperatively. RESULTS: The cohort included 158 patients, of whom 109 (69%) were treated postoperatively with RAI (mean dose, 131 mCi) and 49 were not (control group). Sonographic changes were observed in the major salivary glands in 43% of the study group and 18% of the control group (p = 0.002), including coarse echotexture, decreased echogenicity, fibrosis, and atrophy. Higher RAI doses were significantly correlated with the prevalence and severity of glandular changes (p < 0.0001). CONCLUSION: RAI treatment following thyroidectomy is associated with a dose-response effect and adverse changes in the major salivary glands and should be prescribed carefully.

Tumor Satellites Are Associated With Poor Outcome in Patients With Oral Cancer.

OBJECTIVES: Tumor satellites are defined as islands of tumor cells completely separated from the border of the main tumor. They are believed to be a sign of aggressive disease. Our goal was to investigate the association between tumor satellites and outcome in patients with oral squamous cell carcinoma. MATERIALS AND METHODS: A retrospective analysis of all patients treated for oral squamous cell carcinoma at a university-affiliated tertiary care center between 2010 and 2018 was performed. Data collected included demographics, clinical and pathological features including tumor satellites, staging, treatment modalities, and outcomes. RESULTS: A total of 144 patients were included. The mean age of all patients was 63.5 and 50.7% were males. The mean follow-up time was 40.5 months. Seventeen patients (11.8%) had tumor satellites. These patients had a higher rate of involved margins, peri-neural invasion, lympho-vascular invasion, and extra-nodal extension. Tumor, nodal and overall classification were significantly more advanced in patients with satellites. Disease-specific and overall survival rates were significantly lower among satellites patients (28.7% vs. 59.7% and 28.7% vs. 54.9%, respectively). CONCLUSIONS: Tumor satellites are associated with several adverse features and advanced locoregional disease. Patients with satellites should be treated aggressively with a combination of surgery aimed at achieving free surgical margins and adjuvant treatment, as they have a worse prognosis compared with patients without satellites. Further prospective studies are mandatory to consolidate the importance of adjuvant treatment in these patients. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:336-343, 2023.

Quality of life following lobectomy versus total thyroidectomy is significantly related to hypothyroidism.

OBJECTIVE: The aim of the present study was to investigate the differences in quality of life (QOL) following complete or partial thyroidectomy and with regard to thyroid hormone replacement (LT4) therapy. STUDY DESIGN: Patients who underwent thyroidectomy were asked to complete the validated thyroid-specific ThyPRO QOL questionnaire at least 6 months following surgery. SETTING: Tertiary medical center. METHODS: Thyroid specific QOL questionnaire analysis. RESULTS: A total of 190 patients completed the ThyPRO questionnaire. Of them 89 patients had complete thyroidectomy and 101 patients had unilateral thyroid lobectomy. The total thyroidectomy group had significantly worse overall QOL self-assessment score than the lobectomy patients (p < 0.0001). Patients receiving LT4 therapy regardless of the extent of surgery, reported worse QOL compared to patients not receiving LT4. CONCLUSIONS: Quality of life following thyroid surgery is significantly related to hypothyroidism and the requirement for LT4 therapy, rather to the extent of surgery. The best QOL was reported in patients treated with lobectomy who did not require LT4 therapy.

Retrospective analysis of the role of intra-operative parathyroid hormone monitoring during parathyroidectomy for primary hyperparathyroidism: a single center experience over 2 decades.

PURPOSE: Role of intra-operative parathyroid hormone (IOPTH) monitoring during parathyroidectomy for primary hyperparathyroidism (PHPT) has long been debated. Our main goal was to investigate the cure rates of parathyroidectomy for primary hyperparathyroidism with and without IOPTH monitoring. Our secondary goal was to investigate if operating room time can be saved when IOPTH monitoring is not used. METHODS: A retrospective analysis of patients who underwent parathyroidectomy for PHPT due to a single adenoma between 2004 and 2019 was performed. Cure rates and operating room time were compared. RESULTS: 423 patients were included. IOPTH was used in 248 patients (59%). Four patients were not cured, two from each group, with no significant difference between the groups (98.8% vs. 99.1%, p = 0.725). Surgery time was significantly longer in the IOPTH group, p < 0.001. CONCLUSIONS: There is no advantage for using IOPTH during parathyroidectomy in suitable clinical settings. The procedure may be safely performed without IOPTH while achieving non-inferior success rates and reducing operative time.

Patterns of Regional Recurrence and Salvage Treatment in Patients With Oral Cancer.

OBJECTIVES: Regional failure after primary treatment for oral squamous cell carcinoma (OSCC) carries a dismal outcome. Our goal was to investigate the recurrence patterns and salvage treatment in patients with OSCC and regional failure. STUDY DESIGN: Retrospective chart review of all patients treated for OSCC in a university-affiliated tertiary care center during 2000-2018. METHODS: Data collected from patients' medical charts included demographics, clinical and pathological features, staging, treatment modalities and outcomes. Patients with insufficient data or a follow-up of less than 2 years were excluded. RESULTS: Out of 266 surgically treated patients, 55 developed regional recurrence and were included in the study cohort. Forty patients received surgical salvage treatment followed by adjuvant chemo-radiotherapy (CRT). Disease specific survival and overall survival were significantly higher in surgically treated patients compared to patients who received non-surgical treatment (46.7% vs. 0%, log-rank P value < .001 and 35.3% vs. 0%, log-rank P value = .001, respectively) and in patients who recurred regionally more than 10 months following initial treatment (40.8% vs 10.7%, log-rank P value = .065). Patients with early recurrence were older (73.6 vs. 61.3 years) and had a deeper invasion of the primary tumor (10.1 vs. 7 mm). CONCLUSIONS: Salvage neck dissection is feasible in most cases, providing the best outcomes in patients with OSCC who fail regionally. Close follow-up during the first year after initial treatment is paramount as early recurrence carries a dismal prognosis. Specifically, elderly patients and patients with deeper primary tumor invasion should be closely monitored during the first post-operative year. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:786-792, 2022.

Implementation of a Novel Protocol for Preventing Venous Thromboembolism in Otolaryngology Patients.

OBJECTIVE: Venous thromboembolism (VTE) is a preventable cause of postoperative morbidity and mortality. The Caprini risk assessment model (CRAM) is a validated tool for estimating the risk for postoperative VTE. Previous studies demonstrated a low risk of VTE among otorhinolaryngology-head and neck surgery (ORL-HNS). Hence, our objective was to modify the CRAM-based protocol to be applicable for otolaryngology patients and assess protocol efficacy and safety. STUDY DESIGN: Observational pilot study conducted on ORL-HNS patients undergoing surgery. SETTING: University-affiliated tertiary care center. METHODS: We constructed a modified protocol based on the CRAM and previous reports in the ORL-HNS literature using a reduced postoperative anticoagulation regimen. Primary end point was symptomatic VTE up to 3 months after surgery. Main secondary outcome was postoperative bleeding. RESULTS: A total of 508 patients were enrolled. Of them, 48% underwent head and neck surgery, 18% direct laryngoscopy and transoral robotic surgery, 15% endoscopic sinus surgery, and 11% otology surgery. Adherence to the protocol was 79%. Mean follow-up time was 115 days (range, 30-448 days). Only 1 patient developed deep vein thrombosis, and none developed pulmonary embolism. Two patients had major bleeding not related to the use of anticoagulation. CONCLUSIONS: Our novel CRAM-based protocol appears to be efficacious and safe for VTE prevention in otolaryngology. A larger-scale study is required to validate these findings. LEVEL OF EVIDENCE: Level 2b.

Major head and neck surgeries in the elderly population, a match-control study.

BACKGROUND AND OBJECTIVES: To investigate complication rates in elderly cancer patients undergoing major head and neck surgeries. METHODS: A retrospective, matched-control, analysis. For each elderly (≥70 years) patient, a younger, (<70 years) patients were matched based on sex, tumor location, disease stage, and operation time. Post-operative complication and survival analyses were performed. RESULTS: Of 225 patients, 75 (33.3%) were elderly (mean age 76.2 (70-88) years) and compared with a match control group (53.2 (23-69) years). A higher rate of cardio-vascular comorbidity was noted in the elderly group (70.6% vs. 34%, respectively, P < 0.001). The majority (62.7%) of elderly patients required reconstruction with 24% receiving vascularized flap reconstruction. Total postoperative complication rate was 49.9% in the study versus 42.3% in the control group, with a major complication rate of 22.5% in the elderly versus 11.9% in the control group (P = 0.154). Mean follow-up was 41 (0-144) months. Five-year disease-specific (67.1% vs. 80.7%, P < 0.001) and overall survival rates (48.6% vs. 75.4%, P < 0.001) were significantly lower among elderly patients. CONCLUSIONS: Major head and neck surgery in the elderly population does not entail higher complication rate, compared with younger patients, and should be allowed when curative intent is feasible and patient's general condition allows.

Radioiodine therapy induced sialadenitis versus chronic idiopathic sialadenitis-Presentation and outcomes.

BACKGROUND: This study explores the unique characters of high dose radioactive iodine (RAI) induced chronic sialadenitis. METHODS: A retrospective study of patients having received salivary endoscopy and followed in our outpatient clinic. RESULTS: A total of 100 patients met the inclusion criteria, 75 were diagnosed with chronic idiopathic sialoadenitis and 25 with radio-iodine induced sialoadenitis (RIS). The main complaint in both groups was swelling of the parotid gland. Pain, dysphagia, and xerostomia were observed considerably more in the RIS group. During sialo-endoscopy, fibrosis of the Stensen's duct was more common in the RIS group (p = 0.003). RIS patients group generally managed better with interventional endoscopic treatment alone (80% vs. 46%). CONCLUSION: RIS patients have distinct clinical characteristics. There may be a collateral muscular damage to the masticatory muscles. Fibrosis and parenchymal damage are major findings during sialendoscopy. Sialendoscopy is a safe and efficient treatment for RAI induced sialadenitis.

Accuracy, predictability and prognostic implications of fine-needle aspiration biopsy for parotid gland tumours: A retrospective case series.

OBJECTIVE: To evaluate the precision and utility of fine-needle aspiration (FNA) in differentiating between benign and malignant parotid tumours, and the implications of FNA results on management and outcomes. DESIGN: Retrospective case series. SETTING: Tertiary medical centre. PARTICIPANTS: All adults who underwent preoperative FNA, followed by postoperative histological examination, between 1986 and 2014. MAIN OUTCOME MEASURES: Differences in clinical management and outcomes of patients with parotid masses in light of FNA results. RESULTS: We analysed 505 samples from 485 patients. According to histopathological results, preoperative FNA successfully identified benign tumours in 89% of the cases (362/405) and only 59% of malignant tumours (59/100). Overall sensitivity and specificity of FNA in distinguishing between different subtypes of benign lesions were 80% and 99%, respectively, whereas positive predictive value (PPV) and negative predictive value (NPV) were 85% and 98%. Moreover, malignant lesions subtyping had high false-positive and false-negative rates with sensitivity, specificity, PPV and NPV of 44%, 100%, 75% and 99%, respectively. Additionally, when FNA falsely classified malignant tumours as benign, surgeries were inappropriately delayed and the durations of surgeries and hospitalisations were shorter, compared to true malignant FNA results. Interestingly, survival was not affected in falsely benign lesions that were mostly low-grade, conversely non-diagnostic FNA for malignant tumours resulted in decreased survival. CONCLUSIONS: Our findings highlight the limitations of FNA as a decision-making tool in preoperative evaluation of parotid masses. Clinicians should take into account that FNA is inaccurate for identifying specific subtypes of malignant lesions, which may eventually delay treatment and influence outcome.

Bioelectrical Impedance Analysis in Patients Undergoing Major Head and Neck Surgery: A Prospective Observational Pilot Study.

BACKGROUND: Head and neck patients are prone to malnutrition. Perioperative fluids administration in this patient group may influence nutritional status. We aimed to investigate perioperative changes in patients undergoing major head and neck surgery and to examine the impact of perioperative fluid administration on body composition and metabolic changes using bioelectrical impedance. Furthermore, we sought to correlate these metabolic changes with postoperative complication rate. In this prospective observational pilot study, bioelectrical impedance analysis (BIA) was performed preoperatively and on postoperative days (POD) 2 and 10 on patients who underwent major head and neck surgeries. BIA was completed in 34/37 patients; mean total intraoperative and post-anesthesia fluid administration was 3682 ± 1910 mL and 1802 ± 1466 mL, respectively. Total perioperative fluid administration was associated with postoperative high extra-cellular water percentages (p = 0.038) and a low phase-angle score (p < 0.005), which indicates low nutritional status. Patients with phase angle below the 5th percentile at POD 2 had higher local complication rates (p = 0.035) and longer hospital length of stay (LOS) (p = 0.029). Multivariate analysis failed to demonstrate that high-volume fluid administration and phase angle are independent factors for postoperative complications. High-volume perioperative fluids administration impacts postoperative nutritional status with fluid shift toward the extra-cellular space and is associated with factors that increase the risk of postoperative complications and longer LOS. An adjusted, low-volume perioperative fluid regimen should be considered in patients with comorbidities in order to minimize postoperative morbidity.

Prophylactic central neck dissection has no advantage in patients with metastatic papillary thyroid cancer to the lateral neck.

BACKGROUND: Papillary thyroid cancer (PTC) usually metastasizes via lymphatic channels in a sequential fashion, first to the central compartment, followed by the lateral neck. PTC patients diagnosed with lateral neck disease (N1b) without proof for central involvement traditionally undergo prophylactic central neck dissection (pCND). However, substantial evidence on outcomes to support this approach is lacking. MATERIALS AND METHODS: We conducted a dual center retrospective study to compare the rate of central neck recurrence between N1b PTC patients undergoing pCND and those spared pCND. All patients diagnosed with N1b PTC who underwent total thyroidectomy and lateral neck dissections with or without pCND between January 1998 and December 2015 were included in this study. The rates of central neck recurrences were compared between the groups. RESULTS: The 111 patients who met the inclusion criteria were 44 females (39.6%) and 67 males (60.4%), with a mean age of 50.2 ± 17.7 years, and a mean follow-up of 10.2 ± 5.3 years. Sixty patients (54.1%) underwent a pCND and 51 patients (45.9%) did not (non-pCND). During follow-up, 18 patients (16.2%) had level VI recurrences, 13 in the pCND group and 5 in the non-pCND group. Cox-regression models with propensity scoring did not reveal any inclination or an advantage for performing pCND. CONCLUSION: The present study demonstrated no advantage in performing pCND to prevent central neck recurrence among PTC patients with lateral neck involvement only. These findings question the need for pCND in patients without clinical evidence of central neck disease.
