AbstractGraves’ disease (GD) can be managed by antithyroid drugs (ATD), radioactive iodine (RAI) and surgery. Thyroidectomy offers the highest success rates for both primary and persistent disease, yet it is the least recommended or utilized option reaching <1% for primary disease and <25% for persistent disease. Several surveys have found surgery to be the least recommended by endocrinologists worldwide. With the development of remote access thyroidectomies and intraoperative nerve monitoring of the recurrent laryngeal nerve, combined with current knowledge of possible risks associated with RAI or failure of ATDs, revaluation of the benefit to harm ratio of surgery in the treatment of GD is warranted. The aim of this review is to discuss possible reasons for the low proportion of surgery in the treatment of GD, emphasizing an evidence‐based approach to the clinicians’ preferences for surgical referrals, surgical indications and confronting traditional reasons and concerns relating to the low referral rate with up‐to‐date data.

Purpose: To review the current options in the management of Warthin tumors (WTs) and to propose a working management protocol. Methods: A systematic literature search was conducted using PubMed and ScienceDirect database. A total of 141 publications were selected and have been included in this review. Publications were selected based on relevance, scientific evidence, and actuality. Results: The importance of parotid WTs is increasing due to its rising incidence in many countries, becoming the most frequently encountered benign parotid tumor in certain parts of the world. In the past, all WTs were treated with surgery, but because of their slow growth rate, often minimal clinical symptoms, and the advanced age of many patients, active observation has gradually become more widely used. In order to decide on active surveillance, the diagnosis of WT must be reliable, and clinical, imaging, and cytological data should be concordant. There are four clear indications for upfront surgery: uncertain diagnosis; cosmetic problems; clinical complaints, such as pain, ulceration, or recurrent infection; and the patient’s wish to have the tumor removed. In the remaining cases, surgery can be elective. Active surveillance is often suggested as the first approach, with surgery being considered if the tumor progresses and/or causes clinical complaints. The extent of surgery is another controversial topic, and the current trend is to minimize the resection using partial parotidectomies and extracapsular dissections when possible. Recently, non-surgical options such as microwave ablation, radiofrequency ablation, and ultrasound-guided ethanol sclerotherapy have been proposed for selected cases. Conclusions: The management of WT is gradually shifting from superficial or total parotidectomy to more conservative approaches, with more limited resections, and to active surveillance in an increasing number of patients. Additionally, non-surgical treatments are emerging, but their role needs to be defined in future studies.

AbstractBackgroundThe prognostic importance of intraparotid lymph node metastasis (P+) in patients with primary parotid gland carcinoma is unclear.MethodsNineteen retrospective and noncomparative cohort studies, published between 1992 and 2020, met the inclusion criteria and included 2202 patients for this systematic review.ResultsThe pooled prevalence of the P in adult patients in the unselected studies was 24.10% (95% confidence interval = 17.95‐30.25). The number of P+ lymph nodes per patient was counted in only three studies and ranged from 1 to 11. The 5‐year recurrence‐free survival rate based on Kaplan‐Meier analysis varied from 83% to 88% in P− patients compared to 36% to 54% in P+ patients. The average hazard ratio for tumor recurrence in patients with P+ compared to P− was 2.67 ± 0.58.ConclusionsP+ is an independent negative prognostic factor in primary parotid gland cancer and should be included into the treatment planning.

AbstractRecent modifications in the management of well‐differentiated thyroid cancer have resulted in significant alterations in clinical approach. Utilizing a series of preoperative and postoperative risk factors involving both the patient and the disease pathology, we offer the term “staged thyroidectomy” to help organize these risk factors for patients and the endocrine team to optimize management. This approach is intended to incorporate our latest nuanced understanding of certain endocrine pathology and may serve to optimize patient outcomes.

(1) Background: Lateral or total parotidectomy are the standard surgical treatments for malignant parotid tumors. However, some authors have proposed a more limited procedure. (2) Methods: We performed a review of the literature on this topic. Studies were included that met the following criteria: malignant parotid tumors, information about the extent of surgical resection, treated with less than a complete lateral lobectomy, and information on local control and/or survival. Nine articles fulfilled the inclusion criteria. (3) Results: Eight of the nine series reported favorable results for the more limited approaches. Most used them for small, mobile, low-grade cancers in the lateral parotid lobe. Most authors have used a limited partial lateral lobectomy for a presumed benign lesion. The remaining study analyzed pediatric patients treated with enucleation with poor local control. (4) Conclusions: There is weak evidence for recommending less extensive procedures than a lateral parotid lobectomy. In the unique case of a partial lateral parotidectomy performed for a tumor initially thought to be benign but pathologically proved to be malignant, close follow-up can be recommended for low grade T1 that has been excised with free margins and does not have adverse prognostic factors.

Background: Larynx cancer is a common site for tumors of the upper aerodigestive tract. In cases with a clinically negative neck, the indications for an elective neck treatment are still debated. The objective is to define the prevalence of occult metastasis based on the subsite of the primary tumor, T classification and neck node levels involved. Methods: All studies included provided the rate of occult metastases in cN0 larynx squamous cell carcinoma patients. The main outcome was the incidence of occult metastasis. The pooled incidence was calculated with random effects analysis. Results: 36 studies with 3803 patients fulfilled the criteria. The incidence of lymph node metastases for supraglottic and glottic tumors was 19.9% (95% CI 16.4–23.4) and 8.0% (95% CI 2.7–13.3), respectively. The incidence of occult metastasis for level I, level IV and level V was 2.4% (95% CI 0–6.1%), 2.0% (95% CI 0.9–3.1) and 0.4% (95% CI 0–1.0%), respectively. For all tumors, the incidence for sublevel IIB was 0.5% (95% CI 0–1.3). Conclusions: The incidence of occult lymph node metastasis is higher in supraglottic and T3–4 tumors. Level I and V and sublevel IIB should not be routinely included in the elective neck treatment of cN0 laryngeal cancer and, in addition, level IV should not be routinely included in cases of supraglottic tumors.

Objectives/Hypothesis Pharyngocutaneous fistulae (PCF) are known to occur in nearly one‐third of patients after salvage total laryngectomy (STL). PCF has severe impact on duration of admission and costs and quality of life and can even cause severe complications such as bleeding, infection and death. Many patients need further surgical procedures. The implications for functional outcome and survival are less clear. Several studies have shown that using vascularized tissue from outside the radiation field reduces the risk of PCFs following STL. This review and meta‐analysis aims to identify the evidence base to support this hypothesis. Data Sources English language literature from 2004 to 2013 Review Methods We searched the English language literature for articles published on the subject from 2004 to 2013. Results Adequate data was available to identify pooled incidence rates from seven articles. The pooled relative risk derived from 591 patients was 0.63 (95% CI: 0.47 to 0.85), indicating that patients who have flap reconstruction/reinforcement reduced their risk of PCF by one‐third. Conclusion This pooled analysis suggests that there is a clear advantage in using vascularized tissue from outside the radiation field in the laryngectomy defect. While some studies show a clear reduction in PCF rates, others suggest that the fistulae that occur are smaller and rarely need repair. Laryngoscope , 124:1848–1853, 2014

AbstractDesmoid tumor, or aggressive fibromatosis, is a rare, histologically benign, fibroblastic lesion that infrequently presents in the head and neck. Desmoid tumors often grow locally, invasively, and may, in rare instances, be fatal secondary to invasion into critical structures, such as airway or major vessels. The most common treatment is surgery, but desmoid tumors are characteristically associated with a high local recurrence rate after resection. Although the margin status seems to be of importance, operations that avoid function loss and esthetic disfigurement should be the primary goal. The efficacy of postoperative radiotherapy is controversial. Its potential benefit should be carefully balanced against possible radiation‐induced adverse effects. Alternative treatment modalities, such as primary radiotherapy and medical treatment or a wait‐and‐see policy, may be preferable to mutilating surgery. Considering all the aforementioned, it seems obvious that desmoid tumors of the head and neck present a therapeutic challenge and require an individualized approach. © 2014 Wiley Periodicals, Inc.Head Neck, 36: 1517–1526, 2014

Gastroesophageal reflux disease (GERD), or its variation known as laryngopharyngeal reflux (LPR), has been recognized as a potential cause of several laryngeal disorders. Patients with laryngeal cancer have lifestyle risk factors, especially tobacco and alcohol consumption, that play an etiological role in the development of their cancer but also places them at risk for reflux. The question then arises whether there is merely an association or a causal relationship between laryngeal cancer and reflux. However, despite a number of studies, a causal relationship with laryngeal cancer is uncertain. In this article, we address the current literature in a critical manner to evaluate the relationship between reflux and laryngeal cancer. From the review of the literature, we conclude that there is insufficient evidence to support a causal role of reflux in laryngeal cancer, mainly because of the confounding effect of tobacco and alcohol consumption and the inaccuracies in the diagnosis of reflux. © 2013 Wiley Periodicals, Inc.
