ABSTRACT
OBJECTIVE: Resection of the vestibular schwannoma causes acute peripheral vestibular loss. The process of central compensation starts immediately afterward. The rehabilitation goal is to support this process and restore the quality of life. MATERIALS AND METHODS: In this prospective single-center study, 67 consecutive patients underwent vestibular schwannoma resection (40 females, mean age 52 ± 12 years). The patients were divided into three groups: the prehabilitation with intratympanic gentamicin group, the virtual reality group (optokinetic stimulation via virtual reality goggles in the first ten days after the surgery), and the control group. All patients were examined with objective methods and completed questionnaires before the prehabilitation, before the surgery, at the hospital discharge, and after three months. RESULTS: Intratympanic gentamicin prehabilitation leads ipsilaterally to a significant aVOR reduction in all semicircular canals (p < 0.050), the increase of the unilateral weakness in air calorics (p = 0.026), and loss of cVEMPs responses (p = 0.017). Prehabilitation and postoperative exposure to virtual reality scenes improved the patient's perception of vertigo problems according to Dizziness Handicap Inventory (p = 0.039 and p = 0.076, respectively). These findings conform with the optokinetic testing results, which showed higher slow phase velocities at higher speeds (40 deg/s) in both targeted groups compared to the control group. CONCLUSION: Preoperative intratympanic gentamicin positively affects peripheral vestibular function, influencing balance perception after VS resection. In long-term follow-up, prehabilitation and postoperative exposure to virtual reality improve patients' quality of life in the field of vertigo problems.
ABSTRACT
OBJECTIVE: One of the possible risks of sinonasal malignancy is its possible spread in the orbit. However, there is no clear consensus among the different departments as to whether it is necessary to exenterate the orbit in limited tumorous infiltration of periorbital fat. The purpose of the study was to demonstrate that periorbital infiltration and periorbital fat invasion without involvement of deeper orbital tissues are not the indication of orbital exenteration. MATERIALS AND METHODS: Retrospective analysis was performed over a 17-year period of patients undergoing surgical treatment for sinonasal malignancy with histologically verified periorbital infiltration or deeper invasion into the orbit. A total of 32 patients were included in the study. For each group, the following data were analysed: sex, age, preoperative imaging studies, histological findings, site of origin, stage, surgical reconstruction, oncological treatment, survival, cause of death, number of recurrences in the orbit and functional status of preserved eyes. RESULTS: Based on our criteria for orbital exenteration, orbital preservation was feasible in 18 patients. Orbital exenteration was performed in 14 patients with deeper tumor infiltration. There was a statistically insignificant difference in survival between the two groups. The 5-year overall survival (OS) was 44% for the orbital preservation group (only 2 patients died from local tumor recurrence) and 34% for the orbital exenteration group. The groups did not differ in other observed factors other than the extent of orbital infiltration. In 11 (61.1%) patients, vision was without significant change after radiation therapy. In 2 (11.1%) patients, visual function was impaired due to diplopia. 5 (27.8%) patients had severely impaired vision due to optic nerve atrophy after radiation therapy. CONCLUSIONS: Our results show a relatively high survival rate in the group of patients with orbital preservation with a high chance of vision preservation, which justifies our approach to orbital preservation even in some tumors with periorbital infiltration.
ABSTRACT
Introduction: Head and neck paragangliomas (HNPGLs) are rare neuroendocrine tumors, which are mostly benign in nature. Amongst all genes, Succinate Dehydrogenase Subunit D (SDHD) is the most commonly mutated in familial HNPGLs. In about 30% of HNPGLs, germline mutations in SDHD can also occur in the absence of positive family history, thus giving rise to "occult familial" cases. Our aim was to evaluate the pattern of SDHD germline mutations in Czech patients with HNPGLs. Materials and methods: We analyzed a total of 105 patients with HNPGLs from the Otorhinolaryngology departments of 2 tertiary centers between 2006 - 2021. All underwent complex diagnostic work-up and were also consented for genetic analysis. Results: Eighty patients aged 13-76 years were included; around 60% with multiple PGLs were males. Carotid body tumor was the most frequently diagnosed tumor. Germline SDHD mutation was found in only 12% of the Czech patients; approximately 78% of those harboring the mutation had negative family history. The mutation traits had higher affiliation for multiple tumors with nearly 70% patients of ≤ 40 years of age. Conclusion: An SDHD mutation variant was shared amongst unrelated patients but no founder-effect was established. Our findings confirmed that the pattern of SDHD mutation distribution amongst HNPGLs in Czech Republic differs from most studies worldwide.

OBJECTIVES: The objective of this study is to address issues faced by doctors working in the COVID-19 units during the second phase of COVID-19 in the Czech Republic, when the country registered the highest per capita rate of new COVID-19 cases in the world. METHODS: A prospective study was designed using Google online questionnaire. Inclusion criteria were doctors from medical and surgical specialties working in COVID-19 units. The Czech Medical Association was approached in obtaining permission and helping us distribute the questionnaire with an introductory message with the aims of the study via email to the chairpersons of 18 medical and surgical Czech Societies and their respective members. The online questionnaire link was active for 31 days. Completion of a questionnaire implied consent to participate. Data was collected from the completed responses and statistical analysis was done. RESULTS: Fifteen out of eighteen invited Societies participated in the study. Out of all the transferred or volunteering doctors at the COVID units, 47.6% were from 9 medical specialties and 52.4% from 6 surgical units. The highest transfers were seen amongst male surgeons with 21 to 35 years of work experience, whilst the youngest group of doctors made the highest contribution. There was no statistical significance between the effects of COVID-19 and gender. Despite adequate medical provisions, 42% of all doctors had issues with procedural diagnostic methods, 40% tested positive for COVID-19 and 31% reported staff reduction leading to diminished patients' admissions and compromised care. Doctors from surgical departments experienced more difficulties in working in COVID-19 units. Furthermore, on contraction of COVID-19, 114 doctors asserted a lack of support and another 26% were unaware of any services. CONCLUSIONS: Our survey reiterates the relationship between factors related to occupational health and safety, standards of patient care and possibility of medicolegal consequences with the continuing COVID-19 pandemic.

PURPOSE: Pleomorphic adenoma (PA), the most common benign tumour of the parotid gland, requires accurate preoperative diagnosis owing to its capacity for malignant transformation. The aim of this study was to evaluate our experience with ultrasound-guided fine-needle aspiration biopsy (FNAB) in the diagnostic algorithm for patients with PA and to assess clinical outcomes for those with different surgical approaches. MATERIAL AND METHODS: We carried out a retrospective analysis of patients treated for parotid gland mass between 2010 and 2016. These had had preoperative FNAB and had undergone subsequent surgery. RESULTS: 165 patients had FNAB with the result of PA and the definitive histology confirmed PA in 159 cases (96.4%). On the other hand, in 179 patients, the definitive histology showed PA and the preoperative FNAB result corresponded in 159 cases (88.9%). The measured sensitivity, specificity and accuracy of ultrasound-guided FNAB in the diagnosis of PA were, respectively, 88.83%, 96.23% and 92.31%. Most of the patients underwent superficial or partial superficial parotidectomy, followed by extracapsular dissection which was associated with statistically lower risk of facial nerve injury (P=0.04). CONCLUSION: Ultrasound-guided FNAB is simple, accurate and valuable in the diagnosis of PA and provides results that can lead to the choice of less invasive operative treatment.
ABSTRACT
BACKGROUND AND AIM: Minimally invasive endoscopic techniques are the treatment of choice for Zenker's diverticulum (ZD). Our objective was to evaluate the results and efficacy of endoscopic and open approaches, to determine whether postoperative C-reactive protein (CRP) serum levels can be used as a marker to exclude the presence of esophageal leakage, and to identify risk factors for development of postoperative leakage and complications. MATERIALS AND METHODS: Patients who underwent transcervical myotomy and diverticulotomy (TMD) or endoscopic cricopharyngeal myotomy (ECM) with CO2 laser for ZD in years 2008-2021 at our department were included in this retrospective study. RESULTS: Of the 101 patients enrolled, 83 patients underwent ECM and 18 TMD. The procedure time of the endoscopic technique was significantly shorter compared to that of transcervical method (p < 0.001). The median time to oral intake was 6 days for ECM and 10.5 days in the TMD group (p < 0.001). There was a 13% (n = 11) and 16.7% (n = 3) symptomatic recurrence rate and 3.6% (n = 3) and 16.7% (n = 3) major complications rate for ECM and TMD groups, respectively. The incidence of contrast leak (CL) evaluated by postoperative swallow study was 8.9% (9 from 83 patients in the ECM group only). In patients with CL, a significant increase in CRP levels on postoperative day (POD) 2 and 3 was detected when compared to patients without CL. CONCLUSIONS: Endoscopic diverticulotomy with CO2 laser represents a safe and efficient treatment of ZD. Elevation of postoperative CRP serum levels over 123.8 mg/L on POD2 and 98.8 mg/L on POD3 may indicate presence of an esophageal leakage.

BACKGROUND: Salivary gland carcinomas (SGC) are extremely rare malignancies with only limited treatment options for the metastatic phase of the disease. Treatment with anti-CD47 antibodies could represent a potent therapy for SGCs by promoting the phagocytic clearance of tumor cells through various mechanisms. However, the efficacy of anti-CD47 therapy is largely dependent on the expression of CD47 within the tumor microenvironment (TME). MATERIALS AND METHODS: In 43 patients with SGC, we were the first to investigate the CD47 expression in both tumor cells and tumor-infiltrating immune cells (TIIC) in the center and periphery of primary tumors. We also correlated the data with the clinicopathological variables of the patients and offered novel insights into the potential effectiveness of anti-CD47 therapy in SGCs. RESULTS: We observed that the CD47+ tumor cells are outnumbered by CD47+ TIICs in mucoepidermoid carcinoma. In the tumor center, the proportion of CD47+ tumor cells was comparable to the proportion of CD47+ TIICs in most histological subtypes. In low-grade tumors, significantly higher expression of CD47 was observed in TIICs in the periphery of the tumor as compared to the center of the tumor. CONCLUSION: The reason for a high expression of 'don't eat me' signals in TIICs in the tumor periphery is unclear. However, we hypothesize that in the tumor periphery, upregulation of CD47 in TIICs could be a mechanism to protect newly recruited leukocytes from macrophage-mediated phagocytosis, while also allowing the removal of old or exhausted leukocytes in the tumor center.

Head and neck squamous cell carcinomas (HNSCC) belong among severe and highly complex malignant diseases showing a high level of heterogeneity and consequently also a variance in therapeutic response, regardless of clinical stage. Our study implies that the progression of HNSCC may be supported by cancer-associated fibroblasts (CAFs) in the tumour microenvironment (TME) and the heterogeneity of this disease may lie in the level of cooperation between CAFs and epithelial cancer cells, as communication between CAFs and epithelial cancer cells seems to be a key factor for the sustained growth of the tumour mass. In this study, we investigated how CAFs derived from tumours of different mRNA subtypes influence the proliferation of cancer cells and their metabolic and biomechanical reprogramming. We also investigated the clinicopathological significance of the expression of these metabolism-related genes in tissue samples of HNSCC patients to identify a possible gene signature typical for HNSCC progression. We found that the right kind of cooperation between cancer cells and CAFs is needed for tumour growth and progression, and only specific mRNA subtypes can support the growth of primary cancer cells or metastases. Specifically, during coculture, cancer cell colony supporting effect and effect of CAFs on cell stiffness of cancer cells are driven by the mRNA subtype of the tumour from which the CAFs are derived. The degree of colony-forming support is reflected in cancer cell glycolysis levels and lactate shuttle-related transporters.
ABSTRACT
INTRODUCTION: The facial nerve surgery belongs to the basic procedures during lateral skull base approaches. Its damage has serious medical and psychological consequences, and therefore mastery of reconstruction and correction techniques should belong to the repertoire of skull base surgeons. The goal of this study was to demonstrate usefulness of electromyographic follow-up in facial nerve reconstruction. MATERIAL AND METHODS: A total of 16 patients underwent hemihypoglossal-facial anastomosis between 2005 and 2017. Most of the primary lesions came from vestibular schwannoma surgery. All patients were examined with electromyography and scored according to the House-Brackmann and IOWA grading scales. Function of the tongue has been evaluated. RESULTS: Ten patients achieved definitive House-Brackmann grade 3 score (62.5%). We did not observe any association with the patient's age, previous irradiation and the etiology of the damage. Electromyography showed pathological spontaneous activity after the first surgery. Incipient regeneration potentials were detected in 4-17 months (average 7.6) and reached maximum in 6.5-18 months (average 16). Electromyographic assessment of the effect of tongue movement showed better mimic voluntary activity by swallowing or by moving the tongue up. There was no relationship between the start of activity and the interval to achieving maximal activity. CONCLUSION: Hemihypoglossal-facial nerve anastomosis is a safe procedure and it is an optimal solution for cases lacking a proximal stump or in the case of reconstruction in the second stage. Electromyography can predict initial reinnervation activity after reconstructive procedures. During subsequent follow-up it can help to discover insufficiently recovering patients, however clinical characteristics are crucial.

PURPOSE: Warthin tumour (WT) management options comprise surgery or follow-up. The purpose of this study was to asses our experience with the follow-up strategy in selected patients with an ultrasound-guided fine-needle aspiration biopsy (FNAB) showing WT. METHODS: We performed a retrospective analysis of patients diagnosed with WT using FNAB between 1.1.2006 and 31.12.2019. Patients were divided into three groups according to the therapeutic approach-immediate surgery, follow-up or surgery and follow-up. RESULTS: 323 patients were diagnosed with WT and met the study's inclusion criteria (154 women, 47.7% and 169 men, 52.3%). 192 patients were operated right after the diagnosis, 109 patients were observed with their first detected tumour and 22 patients had parotid WT surgery and were in the wait-and-scan protocol with a contralateral tumour, recurrence or both. The growth rate (GR) of observed WT was highly variable (mean GR 1.0 mm/year (5%), median GR 0.8 mm (9%), range - 19.7 to +20.0 mm/year). From 131 patients in the follow-up group, 19 patients underwent surgery and definitive histology revealed 17 WTs and 2 adenocarcinomas. However, these 2 patients had changes in sonographic findings at their next control. The mean observation time was 44.7 months (range 12-138 months) in patients followed exclusively at our institution and 50.9 months (range 12-110 months) in patients observed in cooperation with an otorhinolaryngologist at the patients' place of residence. CONCLUSION: Ultrasound-guided FNAB is an accurate and simple method in WT diagnosis and based on its result a follow-up strategy can be chosen for selected patients with WT.

We carried out a survey in the Czech Republic between January and February 2021 to evaluate the impact of COVID-19 on doctors working in the COVID-19 unit. A rise in 250,000 cases were seen in the Czech Republic during the time of the survey. The indirect impact of the disease on doctors working in COVID-19 units and strategies to control the situation in the Czech Republic were evaluated here. About 35% doctors were concerned with health issues, 40% had tested positive for SARS-CoV-2 antigen, 51% reported lack of support for those who had contracted COVID-19 and 163 agreed that medical, psychological counselling and financial services should be provided. Most doctors experienced moderate and severe degrees of psychological impact. Doctors with the least working experience and those with at least 21 to 35 years were most affected. Mental fatigue was the most common reported psychosomatic effect. The effects were higher in doctors who were more concerned about working in COVID-19 units. Around 87% agreed that the best strategy in controlling the situation in the Czech Republic would be 'preventive measures in combination with vaccination'. History shows us that pandemics can occur in multiple waves. Subsequent waves, inadequate support as well as unparalleled workload can lead to a serious rise in psychological disorders amongst HCWs worldwide.

Salivary gland carcinomas (SGCs) are extremely morphologically heterogeneous, and treatment options for this disease are limited. Immunotherapy with immune checkpoint inhibitors (ICIs) represents a revolutionary treatment approach. However, SGCs remain largely resistant to this therapy. An increasing body of evidence suggests that resistance to ICI therapy is modulated by the Fas (CD95)-Fas ligand (FasL, CD178) interplay between tumor cells and immune cells. In this study, we examined the Fas-FasL interplay between tumor cells and tumor-infiltrating immune cells (TIICs) in the center and periphery of SGCs from 62 patients. We found that the Fas-expressing tumor cells accumulated in the center of SGC tumors with increasing tumor stage. Furthermore, this accumulation occurred regardless of the presence of TIICs expressing high levels of FasL. On the contrary, a loss of Fas-expressing TIICs with increasing tumor stage was found in the tumor periphery, whereas FasL expression in tumor cells in the tumor periphery correlated with tumor stage. These data suggest that SGC cells are resistant to FasL-induced apoptosis by TIICs but could utilize FasL to eliminate these cells in high-stage tumors to provide resistance to immunotherapy.
ABSTRACT
PURPOSE: SARS-CoV-2 vaccines are a key step in fighting the pandemic. Nevertheless, their rapid development did not allow for testing among specific population subgroups such as pregnant and breastfeeding women, or elaborating specific guidelines for healthcare personnel working in high infection risk specialties, such as otolaryngology (ORL). This clinical consensus statement (CCS) aims to offer guidance for SARS-CoV-2 vaccination to this high-risk population based on the best evidence available. METHODS: A multidisciplinary international panel of 33 specialists judged statements through a two-round modified Delphi method survey. Statements were designed to encompass the following topics: risk of SARS-Cov-2 infection and use of protective equipment in ORL; SARS-Cov-2 infection and vaccines and respective risks for the mother/child dyad; and counseling for SARS-CoV-2 vaccination in pregnant, breastfeeding, or fertile healthcare workers (PBFHW). All ORL PBFHW were considered as the target audience. RESULTS: Of the 13 statements, 7 reached consensus or strong consensus, 2 reached no consensus, and 2 reached near-consensus. According to the statements with strong consensus otorhinolaryngologists-head and neck surgeons who are pregnant, breastfeeding, or with childbearing potential should have the opportunity to receive SARS-Cov-2 vaccination. Moreover, personal protective equipment (PPE) should still be used even after the vaccination. CONCLUSION: Until prospective evaluations on these topics are available, ORL-HNS must be considered a high infection risk specialty. While the use of PPE remains pivotal, ORL PBFHW should be allowed access to SARS-CoV-2 vaccination provided they receive up-to-date information.

Cancer-associated fibroblasts (CAFs) are one of the most abundant and critical components of the tumor stroma. CAFs can impact many important steps of cancerogenesis and may also influence treatment resistance. Some of these effects need the direct contact of CAFs and cancer cells, while some involve paracrine signals. In this study, we investigated the ability of head and neck squamous cell carcinomas (HNSCC) patient-derived CAFs to promote or inhibit the colony-forming ability of HNSCC cells. The effect of cisplatin on this promoting or inhibiting influence was also studied. The subsequent analysis focused on changes in the expression of genes associated with cancer progression. We found that cisplatin response in model HNSCC cancer cells was modified by coculture with CAFs, was CAF-specific, and different patient-derived CAFs had a different "sensitizing ratio". Increased expression of VEGFA, PGE2S, COX2, EGFR, and NANOG in cancer cells was characteristic for the increase of resistance. On the other hand, CCL2 expression was associated with sensitizing effect. Significantly higher amounts of cisplatin were found in CAFs derived from patients who subsequently experienced a recurrence. In conclusion, our results showed that CAFs could promote and/or inhibit colony-forming capability and cisplatin resistance in HNSCC cells via paracrine effects and subsequent changes in gene expression of cancer-associated genes in cancer cells.

OBJECTIVES: The COVID-19 disease has an incredible impact on both hospital-based and private practices in the field of otorhinolaryngology and head and neck surgery. Practical issues faced by both types of practices have not been well addressed in most studies. A national survey was conducted in April 2020 to identify the challenges faced by otorhinolaryngologists practicing in the Czech Republic. DESIGN: Prospective questionnaire-based study SETTING: Online Google questionnaire sent to the members of the Czech Society of Otorhinolaryngology and Head and Neck Surgery PARTICIPANTS: All doctors practicing Otorhinolaryngology in the Czech Republic with access to the online questionnaire between 15th and 26th April 2020. MAIN OUTCOME MEASURES: The primary aims of the study were to evaluate any significant differences between the two types of practice in the field of Otorhinolaryngology. We formulated null hypotheses stating there were no statistical differences in the preparation and availability of personal protective equipment amongst both practices a month after the first case of COVID-19 in the Czech Republic. Statistical analyses including the Mann-Whitney U test were performed to test the hypotheses. RESULTS: Analysis and results were based on the completion of the entire questionnaire by the doctors. There were no statistically significant differences between both the practices; however, individual analyses of both the practices showed a different outcome. CONCLUSION: Despite our statistical results, it was observed that private practices faced more deficits and were more financially vulnerable. They were also other issues reported by both practices that could compromise the care of patients, functioning of workplaces and support of doctors.

The treatment options for patients with advanced salivary gland cancers (SGCs) are limited. Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment. However, the response to ICI immunotherapy is largely driven by the immune cell signatures within the tumor tissue and the para-tumoral tissue compartments. To date, there are no data on the expression of programed cell death protein-1/programed cell death protein-ligand 1 (PD-1/PD-L1) in SGC, which may enable the implementation of ICI immunotherapy for this disease. Thus, we performed an immunohistochemical analysis of PD-1 and PD-L1 expression in tumor cells and tumor-infiltrating immune cells (TIICs) in the tumor center and periphery of 62 SGC patients. The tumor periphery showed significantly higher expression of PD-L1 in tumor cells than in TIICs. Moreover, peripheral TIICs had significantly higher PD-1 expression than peripheral tumor cells. PD-1-positive tumor cells were detected exclusively in the tumor center of high-grade tumors, and most importantly, the presence of lymph node (LN) metastases and primary tumor stage significantly correlated with the presence of PD-L1-positive tumor cells in the tumor periphery. The PD-1/PD-L1 molecular signatures in SGC are clustered predominantly in the tumor periphery, reflect disease severity, and may predict the response to ICI immunotherapy in SGC patients.
ABSTRACT
BACKGROUND: The SARS-COV-2 virus has more than just an infectious role to play in the society. The rapid spread has also led to significant personal, professional, financial and economic recession globally. Health care professionals are getting seriously compromised due to these issues. No published data are available on the indirect effects of COVID-19 on high-risk medical specialties. Otorhinolaryngology is considered as one such specialty. Hence, we designed a national survey to address these issues. MATERIALS AND METHODS: A google questionnaire was sent to all the otorhinolaryngologists in Czech Republic with the help of the Czech Society of Otorhinolaryngology and Head and Neck Surgery to evaluate the problems they encountered during the first wave of COVID-19. Personal, professional and financial losses were also addressed. Online access to the survey was from 15th April 2020 to 26th April 2020. RESULTS: The psychosomatic indirect impact of the disease affected female doctors than males. Burnout syndrome was the most commonly reported problem. Around 44.75% of all doctors had a combination of health, financial and economic as well as professional development and educational issues. Doctors from private practices faced higher financial losses. CONCLUSIONS: Our study showed that personal, professional and financial disturbances amongst doctors can lead to more serious consequences. With the lack of drastic measures in improving the support system for healthcare workers, the healthcare systems will fail quickly. Adequate support should be made mandatory by health authorities.

AIMS: Total laryngectomy still plays an essential part in the treatment of laryngeal cancer and loss of voice is the most feared consequence of the surgery. Commonly used rehabilitation methods include esophageal voice, electrolarynx, and implantation of voice prosthesis. In this paper we focus on a new perspective of vocal rehabilitation utilizing alternative and augmentative communication (AAC) methods. METHODS AND PATIENTS: 61 consecutive patients treated by means of total laryngectomy with or w/o voice prosthesis implantation were included in the study. All were offered voice banking and personalized speech synthesis (PSS). They had to voluntarily express their willingness to participate and to prove the ability to use modern electronic communication devices. RESULTS: Of 30 patients fulfilling the study criteria, only 18 completed voice recording sufficient for voice reconstruction and synthesis. Eventually, only 7 patients started to use this AAC technology during the early postoperative period. The frequency and total usage time of the device gradually decreased. Currently, only 6 patients are active users of the technology. CONCLUSION: The influence of communication with the surrounding world on the quality of life of patients after total laryngectomy is unquestionable. The possibility of using the spoken word with the patient's personalized voice is an indisputable advantage. Such a form of voice rehabilitation should be offered to all patients who are deemed eligible.

PURPOSE: Surgical treatment of benign parotid tumors has developed in the direction of less invasive procedures in recent years and has raised great debate about the best surgical approach. Aim of this article is to analyse anatomical and other factors that are important in selection of the appropriate surgical technique in treatment of benign parotid tumors. Furthermore, to discuss the risk of complications and recurrent disease according to selected operation. Finally, to define patient selection criteria to facilitate decision making in parotid surgery and become a guide for younger surgeons. METHODS: Literature review and authors' personal opinions based on their surgical experience. RESULTS: All possible surgical techniques for benign parotid surgery with advantages and disadvantages are being described. An algorithm with anatomical and other criteria influencing decision making in benign parotid surgery is presented. CONCLUSION: Surgeons nowadays have many options to choose from for benign parotid surgery. ECD is one of the many surgical techniques available in parotid surgery and can achieve excellent results with proper training and if used for proper indications. PSP is mainly indicated in large tumors of the caudal part of the PG (ESGS level II). SP represents a universal solution in parotid surgery and should be the first technique young surgeons learn. TP has only few but important indications in benign parotid surgery. Surgeons need to carefully consider the patient and his/her preoperative imaging as well as her or his own special expertise to select the most appropriate surgical technique.
