RESUMO
Graves' 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: Determine rates of intra-parotid and neck nodal metastasis, identify risk factors for recurrence, and report outcomes in patients with primary high-grade parotid malignancy who undergo total parotidectomy and neck dissection. MATERIALS & METHODS: Retrospective review of patients undergoing total parotidectomy and neck dissection for high-grade parotid malignancy between 2005 and 2015. The presence and number of parotid lymph nodes, superficial and deep, as well as cervical lymph nodes involved with metastatic disease were assessed. Risk factors associated with metastatic spread to the parotid deep lobe were identified and recurrence rates reported. RESULTS: 75 patients with median follow-up time of 47 months. 35 patients (46.7%) had parotid lymph node metastasis. Seven patients (9.3%) had deep lobe nodal metastasis without metastasis to the superficial lobe nodes. Nine patients (12%) had positive intra-parotid nodes without positive cervical nodes. Cervical nodal disease was identified in 49.3% patients (37/75). Local, parotid-bed recurrence rate was 5.3% (4/75). Regional lymph node recurrence rate was also 5.3% (4/75). Rate of distant metastasis was 30.6% (23/75). The overall disease free survival rate for all patients at 2 and 5 years were 71% and 60% respectively. CONCLUSION: Parotid lymph node metastasis occurred at a similar rate to cervical lymph node metastasis (46.7% and 49.3%, respectively). Deep lobe parotid nodal metastasis occurred in nearly a quarter of patients and can occur without superficial parotid nodal metastasis. Rate of recurrence in the parotid bed, which may represent local or regional recurrence, was similar to regional cervical lymph node recurrence. Total parotidectomy and neck dissection should be considered high-grade parotid malignancy regardless of clinical nodal status.

High-grade transformation (HGT) or dedifferentiation has been described in a variety of salivary gland carcinomas, including acinic cell carcinoma, secretory carcinoma, adenoid cystic carcinoma, epithelial-myoepithelial carcinoma, polymorphous adenocarcinoma, low-grade mucoepidermoid carcinoma, and hyalinizing clear cell carcinoma. High-grade (HG) transformed tumors are composed of a conventional low-grade component characterized by specific microscopic and immunohistochemical features for the given entity, intermingled with or juxtaposed to areas of HG morphology. This is usually either poorly differentiated adenocarcinoma, carcinoma not otherwise specified, or undifferentiated carcinoma, in which the original line of differentiation is lost. The HG component is composed of solid nests of anaplastic cells with large vesicular pleomorphic nuclei, prominent nucleoli, and abundant cytoplasm. Frequent mitoses and extensive necrosis may be present. The Ki-67 labeling index is consistently higher in the HG component. The molecular genetic mechanisms responsible for HGT of salivary gland carcinomas are largely unknown, though p53 inactivation and human epidermal growth factor receptor 2 overexpression and/or gene amplification have been demonstrated in the HG component in a few examples, the frequency varies for each histologic type. Salivary gland carcinomas with HGT are more aggressive than conventional carcinomas, with a higher local recurrence rate and a poorer prognosis. They have a high propensity for cervical lymph node metastasis suggesting a need for a wider resection and neck dissection. HGT of salivary gland carcinoma can occur either at initial presentation or less commonly at the time of recurrence, sometimes following postoperative radiotherapy. The potential for HGT in almost any type of salivary gland carcinoma warrants a thorough sampling of all salivary gland malignancies to prevent oversight of a HG component.

OBJECTIVES: To describe the evolution and recent series on transoral endoscopic vestibular approach thyroidectomy and parathyroidectomy (TOET/PVA). DATA SOURCES: PubMed, Google Scholar. REVIEW METHODS: Review of the available English literature. RESULTS: TOET/PVA may offer several advantages over other remote access thyroidectomy approaches and has been adopted by many centers worldwide with excellent success rates. Indications include benign disease and early thyroid cancer patients. Complication rate is comparable to the trans-cervical approach. The suggested framework has been validated in recent studies and its feasibility confirmed. CONCLUSION: TOET/PVA has now been used to treat thousands of patients worldwide due to low cost, short learning curve and excellent cosmetic outcomes. Further studies will be necessary to demonstrate oncologic non-inferiority and also the true value that is added by the approach.

PURPOSE OF REVIEW: In this narrative review, we discuss the indications for elective and therapeutic neck dissections and the postoperative surveillance and treatment options for recurrent nodal disease in patients with well-differentiated thyroid cancer. RECENT FINDINGS: Increased availability of advanced imaging modalities has led to an increased detection rate of previously occult nodal disease in thyroid cancer. Nodal metastases are more common in young patients, large primary tumors, specific genotypes, and certain histological types. While clinically evident nodal disease in the lateral neck compartments has a significant oncological impact, particularly in the older age group, microscopic metastases to the central or the lateral neck in well-differentiated thyroid cancer do not significantly affect outcome. As patients with clinically evident nodal disease are associated with worse outcomes, they should be treated surgically in order to reduce rates of regional recurrence and improve survival. The benefit of elective neck dissection remains unverified as the impact of microscopic disease on outcomes is not significant.

PURPOSE: Facial nerve electrodiagnostics is a well-established and important tool for decision making in patients with facial nerve diseases. Nevertheless, many otorhinolaryngologist-head and neck surgeons do not routinely use facial nerve electrodiagnostics. This may be due to a current lack of agreement on methodology, interpretation, validity, and clinical application. Electrophysiological analyses of the facial nerve and the mimic muscles can assist in diagnosis, assess the lesion severity, and aid in decision making. With acute facial palsy, it is a valuable tool for predicting recovery. METHODS: This paper presents a guideline prepared by members of the International Head and Neck Scientific Group and of the Multidisciplinary Salivary Gland Society for use in cases of peripheral facial nerve disorders based on a systematic literature search. RESULTS: Required equipment, practical implementation, and interpretation of the results of facial nerve electrodiagnostics are presented. CONCLUSION: The aim of this guideline is to inform all involved parties (i.e. otorhinolaryngologist-head and neck surgeons and other medical specialists, therapeutic professionals and the affected persons) and to provide practical recommendations for the diagnostic use of facial nerve electrodiagnostics.

PURPOSE: Management of the facial nerve is instrumental in the surgical treatment of parotid cancer. METHODS: A literature search was conducted using PubMed and ScienceDirect database. A total of 195 articles were finally included into the analysis, based on relevance, scientific evidence and actuality. RESULTS: In the majority of cases the facial nerve is not involved by tumor. In these cases, identification and preservation of the nerve, in addition to complete tumor removal, are essential for successful surgery. When the nerve is infiltrated by tumor, the affected portion of the nerve must be resected as part of radical parotidectomy. Primary nerve reconstruction or other reanimation techniques give the best long-term functional and cosmetic results. A comprehensive diagnostic evaluation with current imaging and electrophysiological studies will provide the surgeon with the best knowledge of the relationship of the facial nerve to the tumor. Several standardized methods are helpful in finding, dissecting and preserving the nerve during parotid cancer surgery. When radical parotidectomy is indicated, the initial diagnostic work-up can assist in defining the need for adjuvant postoperative therapy and facial reanimation. The aim of rehabilitation is to restore tone, symmetry, and movement to the paralyzed face. CONCLUSIONS: The surgical management of facial paralysis has undergone many improvements in recent years. This review gives an overview of recent advances in the diagnostic work-up, surgical techniques and any necessary rehabilitation of the facial nerve in parotid cancer surgery.

This editorial explores the controversies concerning the surgical management of the deep portion of the parotid gland. Specifically, when should the parotid deep lobe be removed if there is metastatic cancer to a superficial parotid node or when a primary aggressive cancer is found in the superficial lobe? The background, indications, rationale, and results of removing the deep lobe nodes are reviewed. Removal of the deep lobe is done to optimize the oncologic outcome for the patient. Deep lobe parotidectomy plays an important role in the treatment of many parotid gland malignancies.

OBJECT: Swallowing dysfunction is common following transoral (TO) odontoidectomy. Preliminary experience with newer endoscopic transnasal (TN) approaches suggests that dysphagia may be reduced with this alternative. However, the reasons for this are unclear. The authors hypothesized that the TN approach results in less disruption of the pharyngeal plexus and anatomical structures associated with swallowing. The authors investigate the histological and gross surgical anatomical relationship between pharyngeal plexus innervation of the upper aerodigestive tract and the surgical approaches used (TN and TO). They also review the TN literature to evaluate swallowing outcomes following this approach. METHODS: Seven cadaveric specimens were used for histological (n = 3) and gross anatomical (n = 4) examination of the pharyngeal plexus with the TO and TN surgical approaches. Particular attention was given to identifying the location of cranial nerves (CNs) IX and X and the sympathetic chain and their contributions to the pharyngeal plexus. S100 staining was performed to assess for the presence of neural tissue in proximity to the midline, and fiber density counts were performed within 1 cm of midline. The relationship between the pharyngeal plexus, clivus, and upper cervical spine (C1-3) was defined. RESULTS: Histological analysis revealed the presence of pharyngeal plexus fibers in the midline and a significant reduction in paramedian fiber density from C-2 to the lower clivus (p < 0.001). None of these paramedian fibers, however, could be visualized with gross inspection or layer-by-layer dissection. Laterally based primary pharyngeal plexus nerves were identified by tracing their origins from CNs IX and X and the sympathetic chain at the skull base and following them to the pharyngeal musculature. In addition, the authors found 15 studies presenting 52 patients undergoing TN odontoidectomy. Of these patients, only 48 had been swallowing preoperatively. When looking only at this population, 83% (40 of 48) were swallowing by Day 3 and 92% (44 of 48) were swallowing by Day 7. CONCLUSIONS: Despite the midline approach, both TO and TN approaches may injure a portion of the pharyngeal plexus. By limiting the TN incision to above the palatal plane, the surgeon avoids the high-density neural plexus found in the oropharyngeal wall and limits injury to oropharyngeal musculature involved in swallowing. This may explain the decreased incidence of postoperative dysphagia seen in TN approaches. However, further clinical investigation is warranted.

Deep lobe parotidectomy is an important management approach for highgrade primary parotid cancers that metastasize to the deep lobe nodes and for cancers that metastasizes to the deep parotid from a site outside the parotid. This paper reviews the rationale for deep lobe parotidectomy with facial nerve preservation for these parotid cancers. Deep lobe parotid involvement was reviewed in 27 patients. Twelve patients had primary parotid tumors that metastasized to the deep lobe, and 15 had tumors outside the parotid that metastasized to deep parotid nodes. Deep lobe parotidectomy should be considered in patients with a highgrade primary parotid tumor, a cancer that metastasizes to a superficial intraparotid node, or a primary parotid malignancy that metastasizes to a superficial parotid node or a neck node.

Despite remarkable advances in the care of patients with laryngeal cancer over the past several decades, including a growing awareness of therapeutic complications and attention to quality of life, little is known about the causes of mortality in this population. In addition to the laryngeal malignancy itself, acute and late or chronic treatment-associated causes, second primary cancers, intercurrent disease and psychosocial factors are all responsible for patient morbidity and mortality. We examine the current literature related to the causes of death in patients with laryngeal cancer, in the hope of guiding future interventions to improve the longevity and quality of life of individuals with this cancer.

Among patients with head and neck squamous cell carcinoma with a negative neck who are initially treated with (chemo)radiotherapy, a number of cases will recur locally without obvious neck recurrence. There is little information available as to the most efficacious management of the neck in these cases. We have reviewed the literature to see what conclusions can be drawn from previous reports. We conducted a bibliography search on MEDLINE and EMBASE databases. Studies published in the English language and those on squamous cell carcinoma of the oral cavity, nasopharynx, oropharynx, larynx and hypopharynx were included. Data related to neck management were extracted from the articles. Twelve studies satisfied the inclusion criteria. Five studies reported only one treatment plan (either neck dissection or observation), while the others compared neck dissection to observation. The rate of occult metastases ranged from 3.4 to 12 %. The studies included a variable distribution of primary sites and stages of the recurrent primary tumors. The risk of occult neck node metastasis in a clinically rN0 patient correlated with tumor site and T stage. Observation of the neck can be suggested for patients with T1-2 glottic tumors, who recurred with less advanced tumors (rT1-2). For patients with more advanced laryngeal recurrences or recurrence at other high-risk sites, neck dissection could be considered for the rN0 patient, particularly if the neck was not included in the previous radiation fields.

Olfactory neuroblastomas are uncommon malignancies that arise from olfactory receptor cells located high in the nasal cavity. Accurate diagnosis plays a crucial role in determining clinical results and guiding treatment decisions. Diagnosis can be a major challenge for pathologists, especially when dealing with tumours with poor differentiation. The discovery of several molecular and immunohistochemical markers would help to overcome classification difficulties. Due to the paucity of large-scale studies, standardisation of diagnosis, treatment and prediction of outcome remains a challenge. Surgical resection by endoscopic techniques with the addition of postoperative irradiation is the treatment of choice. In addition, it is advisable to consider elective neck irradiation to minimise the risk of nodal recurrence. Molecular characterisation will help not only to make more accurate diagnoses but also to identify specific molecular targets that can be used to develop personalised treatment options tailored to each patient. The present review aims to summarise the current state of knowledge on histopathological diagnosis, the molecular biology and management of this disease.

Intramuscular hemangiomas (IMHs) are uncommon benign vascular lesions, which develop in skeletal muscle. Herein, two cases of IMHs involving the cervical scalene musculature are presented. Such lesions are exceedingly rare, and can be difficult to distinguish from vagal paragangliomas based on clinical presentation, exam, and radiography. Complete surgical excision is the treatment of choice, and was successful in our two index patients. While rare, IMHs of the scalene muscles should be considered in the differential diagnosis of deep neck space masses.

In the past two decades, major modifications in the way we treat head and neck cancers, due to advances in technology and medical oncology, have led to a decline in the use of open surgery as first-line treatment of cancers arising from several primary tumor sites. The incidence of tobacco- and alcohol-related squamous cell carcinoma of the pharynx and larynx has been steadily decreasing, with a rise in the incidence of human papillomavirus-related oropharyngeal tumors and the use of minimally invasive endoscopic surgery and non-surgical treatment modalities has increased in the treatment of all of these tumors. However, open surgery remains the initial definitive treatment modality for other tumors, including tumors of the skin, oral cavity, sinonasal cavities and skull base, salivary glands, thyroid and sarcomas. Selected group of nasal, paranasal, base of the skull and thyroid tumors are also candidates for minimally invasive procedures. For some indications, the rate of open surgery has actually increased in the past decade, with an increase in the incidence of oral cavity, thyroid and skin cancer, an increase in the number of neck dissections performed, and an increase in salvage surgery and free flap reconstruction. The use of minimally invasive, technology-based surgery-with the use of lasers, operating microscopes, endoscopes, robots and image guidance-has increased. Technology, epidemiology and advances in other domains such as tissue engineering and allotransplantations may further change the domains of competencies for future head and neck surgeons.

OBJECTIVES: We assessed the long-term quality of life (QOL) in patients who survived oral cavity squamous cell cancer when they were young and looked for any clinical factors that might adversely affect function and QOL. METHODS: We performed a retrospective case series and questionnaire survey in a tertiary care center. The subjects were consecutive patients treated for oral cancers during a 25-year period, when they were 40 years of age or less. The patients completed the University of Washington Quality of Life questionnaire and the M. D. Anderson Dysphagia Inventory (MDADI). We made an overall descriptive report of swallowing and QOL measures in the study population and looked for any clinical factors associated with functional outcomes. RESULTS: Among the 62 patients treated over the course of 25 years, 46 were alive and disease-free. Twenty-six participated. The median follow-up duration was 14.7 years (range, 3 to 27 years). Age at diagnosis and duration of follow-up did not correlate with overall QOL or health-related QOL. Seventy-seven percent rated their overall QOL as outstanding, very good, or good. The key domains affected by cancer were appearance, mood, saliva, and shoulder function. Radiotherapy significantly adversely affected the QOL. The median MDADI scores on all 4 subscales were at least 85%. Higher T-stage and radiotherapy were significantly associated with lower scores on all subscales. CONCLUSIONS: The long-term health-related QOL in this cohort was quite good. Radiotherapy and tumor stage correlated with swallowing outcomes, and only radiotherapy seemed to adversely affect the overall QOL.

OBJECTIVES: The aims of the study were (1) to review the management strategy and clinical outcomes of all intraparotid facial nerve (FN) schwannomas (PFNSs) treated at a single tertiary academic center from 1975 to 2010 and (2) to summarize all previously reported cases of PFNS in the international literature. STUDY DESIGN: A retrospective cohort study and literature review. METHODS: Fifteen patients were diagnosed and treated at the authors' institution from 1975 to 2010. In addition, 124 published cases were systematically reviewed. RESULTS: The most common presentation of PFNS was a painless parotid mass with normal FN function. Eccentric, loosely attached intraparotid tumors underwent gross total resection with nerve preservation granting satisfactory postoperative FN function, whereas "inseparable" intraparotid tumors were observed in 8 cases with stable long-term size. Lesions that extended into the fallopian canal underwent complete resection with FN sacrifice and nerve grafting in 10 cases, whereas 1 patient received subtotal resection of the intraparotid portion with stereotactic radiotherapy targeting the intratemporal component. CONCLUSIONS: Intraparotid FN schwannomas present similar to other primary salivary gland neoplasms, making an early diagnosis challenging. Intraoperative recognition of gross tumor characteristics and early histologic diagnosis with strategic biopsy are critical. Information including tumor location and extent, preoperative FN function, and the gross relationship between the tumor and the FN may guide the surgeon toward an optimal treatment plan emphasizing long-term neurologic preservation.

PURPOSE: We present our experience with the use of transoral robotic surgery (TORS) for treatment of supraglottic squamous cell carcinoma. MATERIALS AND METHODS: We studied all patients who underwent TORS for supraglottic squamous cell carcinoma, with or without adjuvant therapy, from March 2007 through June 2009, who had a minimum of 2 years of follow-up. Primary functional outcomes included dysphonia, tracheostomy dependence, and gastrostomy tube dependence. Disease control and survival were estimated with the Kaplan-Meier method. RESULTS: Of 9 patients in the study group, 7 (78%) had advanced-stage disease. All 9 patients had negative margins after TORS, with no perioperative complications. Regional recurrence and local recurrence developed in 1 patient each. One patient died of disease. At last follow-up, 7 patients (78%) were tracheostomy free, and 7 (78%) were gastrostomy tube free. CONCLUSIONS: Transoral robotic surgery is a promising modality for resection of supraglottic squamous cell carcinoma. Transoral robotic surgery achieved functional laryngeal preservation in most patients with no complications.

PURPOSE: There is still debate in literature about the survival outcomes of patients who have cancer of the oral cavity when young. Hence the aims were (1) to estimate disease-free survival, overall survival, and cause-specific survival in patients who developed oral cavity squamous cell carcinoma between 18 and 40 years of age and (2) to assess the clinicopathologic factors including detection of human papillomavirus and epidermal growth factor receptor (EGFR) overexpression in primary lesions affecting recurrence. METHODS: This is a retrospective case-note review and reevaluation of histopathologic slides of patients treated more than 25 years. Descriptive statistics, Cox proportional hazard models, and Kaplan-Meier survival curves were used for statistical analysis. RESULTS: A total of 62 patients were treated, with mean follow-up of 11.4 years. Forty-five were oral tongue tumors and 43 had stage I or II disease. The 5-year disease-free survival was 73.5%. The 10-year overall survival and cause-specific survival rates were 81.8% and 83.4%, respectively. Smoking and alcohol intake were not seen as risk factors in this population. Multivariate modeling identified only nodal involvement as significantly associated with overall survival and only extracapsular spread as significantly associated with locoregional recurrence. At 5 years after treatment, the cause-specific survival was 100% for patients with low EGFR expression and 81.1% for patients with high EGFR expression (hazard ratio for high vs low, 3.1; 95% confidence interval, 0.4-406.9; P = .46). Human papillomavirus was not detected in all but 2 tumor specimens. CONCLUSIONS: Survival outcomes are quite good in young patients with oral cancer.

Extensive attention has been directed to lymphedema involving the extremities. However, there has been relatively limited study of the cutaneous lymphatics of the head and neck. In this review of head and neck lymphatics, we capsulize the history of the lymphatics, the anatomy of the cutaneous lymphatics, lymphatic function and physiology, and imaging modalities used to define this intricate vascular system. To appreciate the clinical challenges associated with head and neck lymphatic dysfunction, we also provide an overview of disease processes of the cutaneous lymphatics and their treatment, theories on the etiology of lymphedema, and future directions to better understand lymphatic function and disease. Knowledge of the cutaneous lymphatics of the head and neck are critical to the clinical evaluation of patients, who present with this debilitating condition and to our understanding of its pathogenesis and appropriate management.
