[How much digitization do ENT curricula need? : Opportunities and limits from the perspective of students and teachers]. / Wieviel Digitalisierung braucht die HNO-Lehre? : Chancen und Grenzen aus Sicht von Studierenden und Lehrenden.

BACKGROUND: Digitalization has long been an integral part of students' everyday lives and increasingly also of their medical training. It seems to be an unwritten law that "digital natives" want as much digitalization as possible. This study aims to shed more light on how students in the clinical phase of medical studies perceive the increasing digitalization of teaching and what they need for good education. MATERIALS AND METHODS: This study analyzed two surveys that were conducted using an online questionnaire. On the one hand, students in the 5th-9th semesters of the medical faculty at the University of Hamburg (n = 282) were surveyed (survey 1). Another survey addressed all employees of ENT clinics in Germany (n = 175; survey 2). RESULTS: A total of 76 students took part in survey 1 and 123 lecturers in survey 2. The results show that both students and lecturers do not want face-to-face teaching to be completely replaced by digital formats. A total of 72.7% of students reject the possibility of teaching practical skills through digital formats. The majority of students surveyed stated that offline formats improve their concentration (61.1%), participation probability (63.9%), and motivation to learn (76.6%). In contrast, 40.2% of lecturers see digitalization as a way to reduce the workload without any relevant loss in teaching quality. CONCLUSION: Digital teaching formats have a negative impact on the medical education of the students surveyed. Interaction and physical presence are needed to increase the motivation to learn. This leads to the first conclusion that students are critical of the increasing digitalization of medical studies.

Outcomes following oropharyngeal squamous cell carcinoma resection and bilateral neck dissection with or without contralateral postoperative radiotherapy of the pathologically node-negative neck.

PURPOSE: There are no consensus guidelines regarding the postoperative treatment of the contralateral pathologically node-negative neck in oropharyngeal squamous cell carcinoma. This study aimed to determine if omission of postoperative irradiation of the contralateral pathologically node-negative neck affects oncological outcomes. METHODS: We retrospectively identified 84 patients with primary surgical treatment including bilateral neck dissection and postoperative (chemo-)radiotherapy (PO(C)RT). Survival was analyzed using the log-rank test and the Kaplan-Meier method. RESULTS: Patients showed no decrease in tumor-free, cause-specific (CSS), or overall survival (OS) when PO(C)RT of the contralateral pathologically node-negative neck was omitted. Increased OS was found in patients with unilateral PO(C)RT and especially an increased OS and CSS was found in unilateral PO(C)RT and in tumors arising from lymphoepithelial tissue. CONCLUSIONS: Omitting the contralateral pathologically node-negative neck appears to be safe in terms of survival and our retrospective study advocates further prospective randomized control de-escalation trials.

Lipidome Analysis of Oropharyngeal Tumor Tissues Using Nanosecond Infrared Laser (NIRL) Tissue Sampling and Subsequent Mass Spectrometry.

Ultrashort pulse infrared lasers can simultaneously sample and homogenize biological tissue using desorption by impulsive vibrational excitation (DIVE). With growing attention on alterations in lipid metabolism in malignant disease, mass spectrometry (MS)-based lipidomic analysis has become an emerging topic in cancer research. In this pilot study, we investigated the feasibility of tissue sampling with a nanosecond infrared laser (NIRL) for the subsequent lipidomic analysis of oropharyngeal tissues, and its potential to discriminate oropharyngeal squamous cell carcinoma (OPSCC) from non-tumorous oropharyngeal tissue. Eleven fresh frozen oropharyngeal tissue samples were ablated. The produced aerosols were collected by a glass fiber filter, and the lipidomes were analyzed with mass spectrometry. Data was evaluated by principal component analysis and Welch's t-tests. Lipid profiles comprised 13 lipid classes and up to 755 lipid species. We found significant inter- and intrapatient alterations in lipid profiles for tumor and non-tumor samples (p-value < 0.05, two-fold difference). Thus, NIRL tissue sampling with consecutive MS lipidomic analysis is a feasible and promising approach for the differentiation of OPSCC and non-tumorous oropharyngeal tissue and may provide new insights into lipid composition alterations in OPSCC.

[Comments on the term "drainage"]. / Anmerkungen zum Terminus "Drainage".

BACKGROUND: Use of the term "drainage" is inconsistent in clinical practice and the existing literature. OBJECTIVE: The aim of this study was to clarify the meaning of the term and to raise awareness of its proper use. MATERIALS AND METHODS: A selective literature search was performed. RESULTS: Drainage is the process of removing fluid but the term is often used interchangeably with the drain tube, which is often inserted at the same time, which is linguistically referred to as a metonymy. A tympanostomy tube is used for middle ear ventilation and pressure equalization. Lymphatic and abscess drainage are not objects. CONCLUSION: Standardized technical terminology serves to prevent vagueness and consecutive misunderstandings in a scientific context. This is particularly important in medicine, but is subject to a certain variability in everyday language use.

Analyzing tyrosine kinase activity in head and neck cancer by functional kinomics: Identification of hyperactivated Src family kinases as prognostic markers and potential targets.

Signal transduction via protein kinases is of central importance in cancer biology and treatment. However, the clinical success of kinase inhibitors is often hampered by a lack of robust predictive biomarkers, which is also caused by the discrepancy between kinase expression and activity. Therefore, there is a need for functional tests to identify aberrantly activated kinases in individual patients. Here we present a systematic analysis of the tyrosine kinases in head and neck cancer using such a test-functional kinome profiling. We detected increased tyrosine kinase activity in tumors compared with their corresponding normal tissue. Moreover, we identified members of the family of Src kinases (Src family kinases [SFK]) to be aberrantly activated in the majority of the tumors, which was confirmed by additional methods. We could also show that SFK hyperphosphorylation is associated with poor prognosis, while inhibition of SFK impaired cell proliferation, especially in cells with hyperactive SFK. In summary, functional kinome profiling identified SFK to be frequently hyperactivated in head and neck squamous cell carcinoma. SFK may therefore be potential therapeutic targets. These results furthermore demonstrate how functional tests help to increase our understanding of cancer biology and support the expansion of precision oncology.

Comparative effectiveness trial of transoral head and neck surgery followed by adjuvant radio(chemo)therapy versus primary radiochemotherapy for oropharyngeal cancer (TopROC).

BACKGROUND: For loco-regionally advanced, but transorally resectable oropharyngeal cancer (OPSCC), the current standard of care includes surgical resection and risk-adapted adjuvant (chemo) radiotherapy, or definite chemoradiation with or without salvage surgery. While transoral surgery for OPSCC has increased over the last decade for example in the United States due to transoral robotic surgery, this treatment approach has a long history in Germany. In contrast to Anglo-Saxon countries, transoral surgical approaches have been used frequently in Germany to treat patients with oro-, hypopharyngeal and laryngeal cancer. Transoral laser microsurgery (TLM) has had a long tradition since its introduction in the early 70s. To date, the different therapeutic approaches to transorally resectable OPSCC have not been directly compared to each other in a randomized trial concerning disease control and survival. The goal of this study is to compare initial transoral surgery to definitive chemoradiation for resectable OPSCC, especially with regards to local and regional control. METHODS: TopROC is a prospective, two-arm, open label, multicenter, randomized, and controlled comparative effectiveness study. Eligible patients are ≥18 years old with treatment-naïve, histologically proven OPSCC (T1, N2a-c, M0; T2, N1-2c, M0; T3, N0-2c, M0 UICC vers. 7) which are amenable to transoral resection. Two hundred eighty patients will be randomly assigned (1:1) to surgical treatment (arm A) or chemoradiation (arm B). Standard of care treatment will be performed according to daily routine practice. Arm A consists of transoral surgical resection with neck dissection followed by risk-adapted adjuvant therapy. Patients treated in arm B receive standard chemoradiation, residual tumor may be subject to salvage surgery. Follow-up visits for 3 years are planned. Primary endpoint is time to local or locoregional failure (LRF). Secondary endpoints include overall and disease free survival, toxicity, and patient reported outcomes. Approximately 20 centers will be involved in Germany. This trial is supported by the German Cancer Aid and accompanied by a scientific support program. DISCUSSION: This study will shed light on an urgently-needed randomized comparison of the strategy of primary chemoradiation vs. primary surgical approach. As a comparative effectiveness trial, it is designed to provide data based on two established regimens in daily clinical routine. TRIAL REGISTRATION: NCT03691441 Registered 1 October 2018 - Retrospectively registered.

Survivin expression in head and neck squamous cell carcinomas is frequent and correlates with clinical parameters and treatment outcomes.

OBJECTIVES: Strong expression of survivin is associated with worse survival in many different tumours, and in cell culture, a correlation between radiation resistance and survivin expression can be seen. The potential of survivin expression as a prognostic/predictive marker or therapeutic target has not been examined in head and neck squamous cell carcinomas (HNSCC) yet. MATERIAL AND METHODS: Retrospective study of 452 tissue samples and clinical data from patients with squamous cell carcinomas of the larynx/hypopharynx (LSCC), oral cavity (OSCC) and oropharynx (OPSCC) treated in the University Medical Centre Hamburg-Eppendorf between 2002 and 2006. The expression patterns were detected by tissue microarray technique and correlated with clinical parameters (sex, age, tumour location, TNM 7th edition, grading, recurrence-free and overall survival). RESULTS: 222 OSCC, 126 OPSCC and 105 LSCC tumours of 118 females and 335 males with a mean follow-up of 41.3 months were examined. Survivin expression correlates with pN, cM, pT and overall survival. CONCLUSION AND CLINICAL RELEVANCE: The potential of survivin as a prognostic/predictive marker is very high. The findings have to be confirmed in a larger cohort of HNSCC esp. in those tumours treated primarily with radio/radiochemotherapy.

Comparative treatment planning study on sequential vs. simultaneous integrated boost in head and neck cancer patients: Differences in dose distributions and potential implications for clinical practice.

AIM: The purpose of this work was to compare sequential (SeqB) versus simultaneous integrated boost (SIB) radiotherapy plans delivered with volumetric modulated arc therapy (VMAT) for patients with locally advanced squamous cell cancer of the head and neck (HNSCC). PATIENTS AND METHODS: SeqB and SIB plans using VMAT for 10 HNSCC patients given definitive chemoradiation were generated and analysed for differences in dose distribution, coverage, conformity and homogeneity to the planning target volumes (PTV) 1-3 and sparing of organs at risk (OAR). RESULTS: The mean delineated volumes ± standard deviations were 137.7 ± 44.8, 351.3 ± 83.9 and 895.6 ± 120.5 cm3 for PTV1-3. The mean volumes encompassed by the corresponding 95 % isodoses were 281 (+ 110 %) ± 73.4, 712.2 (+ 115 %) ± 146.4 and 1381.1 (+ 54 %) ± 217.3 cm3 with SeqB and 138.2 (+ 7 %) ± 40.1, 380.4 (+ 11 %) ± 91.9 and 1057.3 (+ 21 %) ± 161.4 cm3 with SIB for PTV1-3, respectively. Both strategies achieved excellent PTV coverage. SeqB provided significantly better coverage of PTV1 and 3, worse conformity for PTV1-3 and a higher mean dose than prescribed (111-115 %) to PTV2 and 3 (p ≤ 0.007). Both strategies provided satisfactory OAR sparing. CONCLUSION: This study showed significant dosimetric differences with potential clinical relevance between two VMAT boost strategies regarding coverage, conformity and dose to the PTVs. SIB might cause less toxicity. A clinical phase III/IV trial endorsed by the German Head and Neck Clinical Trials Group (IAG-KHT) will evaluate differences in acute/late toxicity as well as in locoregional recurrences between the two boost techniques.

Unilateral and bilateral neck SIB for head and neck cancer patients : Intensity-modulated proton therapy, tomotherapy, and RapidArc.

AIM: To compare simultaneous integrated boost plans for intensity-modulated proton therapy (IMPT), helical tomotherapy (HT), and RapidArc therapy (RA) for patients with head and neck cancer. PATIENTS AND METHODS: A total of 20 patients with squamous cell carcinoma of the head and neck received definitive chemoradiation with bilateral (n = 14) or unilateral (n = 6) neck irradiation and were planned using IMPT, HT, and RA with 54.4, 60.8, and 70.4 GyE/Gy in 32 fractions. Dose distributions, coverage, conformity, homogeneity to planning target volumes (PTV)s and sparing of organs at risk and normal tissue were compared. RESULTS: All unilateral and bilateral plans showed excellent PTV coverage and acceptable dose conformity. For unilateral treatment, IMPT delivered substantially lower mean doses to contralateral salivary glands (< 0.001-1.1 Gy) than both rotational techniques did (parotid gland: 6-10 Gy; submandibular gland: 15-20 Gy). Regarding the sparing of classical organs at risk for bilateral treatment, IMPT and HT were similarly excellent and RA was satisfactory. CONCLUSION: For unilateral neck irradiation, IMPT may minimize the dry mouth risk in this subgroup but showed no advantage over HT for bilateral neck treatment regarding classical organ-at-risk sparing. All methods satisfied modern standards regarding toxicity and excellent target coverage for unilateral and bilateral treatment of head and neck cancer at the planning level.

Nodal yield of neck dissections and influence on outcome in laryngectomized patients.

The appropriate extent of neck dissection (ND) in head and neck squamous cell carcinoma (SCC) continues to be investigated. This study aimed to determine whether the extent of ND as measured by nodal yield (NY) is a prognostic factor in patients undergoing primary total laryngectomy (TL) for advanced laryngeal SCC. A retrospective review at a tertiary referral centre identified 54 patients who underwent TL with elective (n = 39, cN0) or therapeutic (n = 15, cN+) ND with curative intent between 2002 and 2014. Survival analysis was obtained via regression analysis, calculated for overall (OS) and disease-free survival (DFS). Stage-independent 5-year OS was 32.1 %. Mean NY was 18.67 (standard deviation 9.898; range 0-45). The rate of cervical lymph node metastasis on pathology (pN+) was 27.8 %. Uni- and multivariate regression analysis detected no association between NY and OS or DFS (P ≥ 0.05). Advantages in OS and DFS were seen among patients without cervical lymph node metastasis (pN0) in comparison to those with pN+ necks (OS: hazard ratio [HR] 0.179; 95 % confidence interval [CI] 0.046-0.693; P = 0.013, and DFS: HR 0.190; 95 % CI 0.061-0.590; P = 0.004). ND resulted in pathologic upstaging of the neck in seven patients and downgrading in eight; increasing NY was not associated with an increased probability of a change in nodal stage. No significant association was found between NY and OS or DFS in patients undergoing TL with ND as primary therapy for advanced laryngeal SCC.

Reduction of thermocoagulative injury via use of a picosecond infrared laser (PIRL) in laryngeal tissues.

The carbon dioxide (CO2) laser is routinely used in glottic microsurgery for the treatment of benign and malignant disease, despite significant collateral thermal damage secondary to photothermal vaporization without thermal confinement. Subsequent tissue response to thermal injury involves excess collagen deposition resulting in scarring and functional impairment. To minimize collateral thermal injury, short-pulse laser systems such as the microsecond pulsed erbium:yttrium-aluminium-garnet (Er:YAG) laser and picosecond infrared laser (PIRL) have been developed. This study compares incisions made in ex vivo human laryngeal tissues by CO2 and Er:YAG lasers versus PIRL using light microscopy, environmental scanning electron microscopy (ESEM), and infrared thermography (IRT). In comparison to the CO2 and Er:YAG lasers, PIRL incisions showed significantly decreased mean epithelial (59.70 µm) and subepithelial (22.15 µm) damage zones (p < 0.05). Cutting gaps were significantly narrower for PIRL (133.70 µm) compared to Er:YAG and CO2 lasers (p < 0.05), which were more than 5 times larger. ESEM revealed intact collagen fibers along PIRL cutting edges without obvious carbonization, in comparison to diffuse carbonization and tissue melting seen for CO2 and Er:YAG laser incisions. IRT demonstrated median temperature rise of 4.1 K in PIRL vocal fold incisions, significantly less than for Er:YAG laser cuts (171.85 K; p < 0.001). This study has shown increased cutting precision and reduced lateral thermal damage zones for PIRL ablation in comparison to conventional CO2 and Er:YAG lasers in human glottis and supraglottic tissues.

Role of panendoscopy in identifying and managing risk of head and neck squamous cell carcinoma in routine follow-up: a retrospective clinical evaluation.

We discuss the clinical effectiveness and predictive value of routine panendoscopy for surveillance and follow-up of head and neck squamous cell carcinoma (HNSCC). Retrospective comparative study. Department of Otolaryngology-Head and Neck Surgery, University Medical Center Hamburg-Eppendorf, Hamburg, Germany. Two hundred and four HNSCC patients (follow-up between 2004 and 2007) were retrospectively evaluated. During follow-up, panendoscopy was performed routinely once a year. To avoid unnecessary procedures, we evaluated the value of radiological and clinical parameters in follow-up. On comparing normal-computerized tomography (CT) vs. abnormal CT results, a 13-fold higher frequency of recurrence (odds ratio 12.74; 95% CI 4.22, 38.48; p < 0.001) was found. Additionally, patient medical history, clinical investigation, and recurrence pattern were significant parameters when detecting a possible recurrence. Panendoscopy could have been avoided in 40% of patients with HNSCC (173/432). A follow-up schedule avoiding routine panendoscopy in HNSCC follow-up when the combination of diagnostic parameters is satisfactory does not influence the sensitivity or specificity of the test.

Laryngeal injuries following endotracheal intubation in ENT surgery: predictive value of anatomical scores.

Endotracheal intubation has been associated with a threefold higher incidence of laryngopharyngeal complaints following anesthesia in comparison to laryngeal mask airway. Such complaints, including hoarseness and sore throat, have been reported in up to 90% of patients within 24 h of extubation. The purpose of this study was to determine which preoperatively documented clinical and anatomic parameters are predictive of laryngo-pharyngeal trauma resulting from elective endotracheal intubation. Fifty-three patients undergoing ENT procedures requiring general anesthesia with endotracheal intubation were recruited. Pre and postoperative laryngostroboscopic examination was performed and findings correlated to preoperative clinical and anatomic parameters. Readily assessed anatomic parameters including height (>180 cm) and weight (>80 kg) correlated significantly to the Eckerbom grade of intubation-associated acute laryngeal injury (rs = 0.374; p = 0.006 and rs = 0.278; p = 0.044, respectively). The mandibular protrusion test also correlated significantly to the Eckerbom grade (rs = 0.462, p = 0.001) while the upper-lip-bite test showed significant correlation to impaired vocal fold oscillation (rs = 0.288, p = 0.036), with injury prediction sensitivities of 37.5 and 39.4%, respectively. No parameters correlated to subjective complaints (n = 5, 9.2%). This study provides suggestions on how to improve the classification of intubation-associated laryngeal injuries as well as providing the basis for larger clinical trials in other surgical subspecialties.

Use of a microsecond Er:YAG laser in laryngeal surgery reduces collateral thermal injury in comparison to superpulsed CO2 laser.

Despite causing significant thermocoagulative insult, use of the carbon dioxide (CO2) laser is considered gold standard in surgery for early stage larynx carcinoma. Limited attention has been paid to the use of the erbium:yttrium-aluminium-garnet (Er:YAG) laser in laryngeal surgery as a means to reduce thermal tissue injury. The objective of this study is to compare the extent of thermal injury and precision of vocal fold incisions made using microsecond Er:YAG and superpulsed CO2 lasers. In the optics laboratory ex vivo porcine vocal folds were incised using Er:YAG and CO2 lasers. Lateral epithelial and subepithelial thermal damage zones and cutting gap widths were histologically determined. Environmental scanning electron microscopy (ESEM) images were examined for signs of carbonization. Temperature rise during Er:YAG laser incisions was determined using infrared thermography (IRT). In comparison to the CO2 laser, Er:YAG laser incisions showed significantly decreased epithelial (236.44 µm) and subepithelial (72.91 µm) damage zones (p < 0.001). Cutting gaps were significantly narrower for CO2 (878.72 µm) compared to Er:YAG (1090.78 µm; p = 0.027) laser. ESEM revealed intact collagen fibres along Er:YAG laser cutting edges without obvious carbonization, in comparison to diffuse carbonization and tissue melting seen for CO2 laser incisions. IRT demonstrated absolute temperature rise below 70 °C for Er:YAG laser incisions. This study has demonstrated significantly reduced lateral thermal damage zones with wider basal cutting gaps for vocal fold incisions made using Er:YAG laser in comparison to those made using CO2 laser.

An unusual clinical presentation of a plunging ranula-The plunging ranula with extension to the vallecula.

Key Clinical Message: A plunging ranula may present initially as an extensive vallecular cyst and correct diagnosis may be reached with the use of ultrasound, fluid aspiration for amylase detection, and MRI imaging. Abstract: The ranula is a pseudocyst of the sublingual salivary gland and can be divided into two known subtypes. The simple ranula and plunging ranula. While the simple type can be found in the floor of the mouth, the plunging ranula usually pervades the mylohoid muscle and presents as a cervical swelling. The presented case should outline the difficulties in diagnostic and treatment of an uncommon expression of a mucocele above the mylohoid muscle without presenting either a cervical or an intraoral swelling, only extending towards the vallecula. We present a previously unreported clinical manifestation of a ranula of an 18-year old male, which extends posteriorly, remaining confined in the supramylohyoid muscle space. The cystic lesion protrudes in the oropharynx, and clinically appears as an extensive vallecular cyst. On magnetic resonance imaging the initial suspected diagnosis of a vallecular cyst was changed to the final diagnosis of a plunging ranula. The marsupialization of the cyst sac was performed. Outpatient follow-up revealed a persisting ostium, indicating a continuous extravasation of the sublingual gland. The present case report describes an unusual clinical presentation of a plunging ranula, remaining above the mylohyoid muscle and protruding into the oropharynx, misdirecting to the first suspected diagnosis of a vallecular cyst. The case highlights the useful contribution of the MRI imaging for differential diagnoses and the need for criteria to indicate further investigations.

The "fascia taco" for nasal septum perforation closure-A retrospective Cohort study on success rates and patient reported outcomes.

Objective: Nasal septum perforation (NSP) is a common condition affecting ~1.2% of the general population and is still considered challenging to treat. Therapeutic strategies range from conservative local treatments and septal button closures to over 40 different surgical approaches. This study aimed to present a novel secure approach. Methods: We describe our novel and unique NSP closure approach using a "fascia taco," in which conchal cartilage is enveloped by temporalis fascia like a taco and splints are left in place for 6-8 weeks. A review of patient charts was conducted and questionnaires including the German-SNOT-22 and D-NOSE were sent by mail to all eligible patients who received a fascia taco between 2016 and 2021. Results: Thirty-three patients were identified. The questionnaire response rate was 54.5%. The mean operative time (cut to sew) for all patients who only underwent NSP closure was 90.4 min. The overall success rate in terms of postoperative NSP closure was 81.8%. We found an apparent but nonsignificant association between closure failure and smoking (failure rate 66.6% in smokers vs. 15.4% in nonsmokers; X 2 = 3.4188, p = .064). Questionnaire analysis showed a significant postoperative reduction of mean values in D-NOSE from 60.8 to 33.1 (p = .009) and in German-SNOT-22 from 38.6 to 21.2 (p = .005). Conclusion: The fascia taco technique is an easy-to-apply, safe procedure for NSP closure that is short in duration and associated with a low morbidity, resulting in excellent patient satisfaction. Level of Evidence: 4.

Nasoseptal Flap for Skull Base Reconstruction in a Three-Year-Old Child With Nasofrontal Meningoencephalocele.

Congenital anterior skull base defects with meningoencephaloceles causing nasal obstruction and cerebrospinal fluid (CSF) rhinorrhea are rare clinical entities. Traditionally, skull base defects have been repaired via a bifrontal craniotomy. With the introduction of pediatric endoscopic instrumentation, more of these lesions are accessible via an intranasal endoscopic approach, even in the infant population. However, due to the rarity of pediatric meningoencephaloceles, there is a lack of data demonstrating the successful adaptation of endoscopic skull base techniques to the pediatric population. In this report, we present a case of a pediatric frontonasal meningoencephalocele with an anterior skull base defect in a 3-year-old child that was successfully addressed transnasally following 4 failed transcranial approaches. The case highlights the importance of a thorough preoperative evaluation of the surgical approach as well as interdisciplinary management of these patients at a young age. Congenital anterior skull base defects with meningoencephaloceles and CSF leaks are rare clinical entities. Hence, an interdisciplinary approach is vital including experienced pediatricians, otolaryngologists, and neurosurgeons to evaluate the ideal surgical method on an individual basis. The transnasal endoscopic technique has been shown to be minimally invasive, efficient, and safe to apply even to the infant population which could positively be demonstrated in this case.

Hereditary head and neck paraganglioma: from basics to practical consequences.

PURPOSE OF REVIEW: This review summarizes practical recommendations for screening, work-up, and management of hereditary head and neck paragangliomas based on the growing molecular and empirical understanding of this disease. RECENT FINDINGS: The proportion of hereditary cases among head and neck paragangliomas is significant (∼33 to 50%), and specific genetic alterations may increase the risk of malignancy. Genotyping should be performed for each case, and patients carrying a pathological mutation should be regularly screened for new tumors. Computed tomography (CT), magnetic resonance imaging (MRI), digital subtraction angiography (DSA), and functional positron emission tomography (PET) can provide a reliable preoperative diagnosis in the absence of histology. Comparative data on therapeutic outcome and morbidity now render radiation, stereotactic radiosurgery, and active surveillance preferable over surgery in highly advanced cases of jugulotympanic and vagal paragangliomas, whereas surgery remains the first choice for most carotid body paragangliomas. SUMMARY: Complete paraganglioma removal continues to be the primary therapeutic goal; however, this is sometimes impossible to accomplish with acceptable morbidity. In these cases, therapy selection should focus on preserving cranial nerve function and minimizing both tumor-associated and therapy-associated complications, particularly in genetically predisposed patients. An interdisciplinary approach to the management of hereditary head and neck paragangliomas is strongly recommended.
