Abstract
Introduction Age and lymph node ratio have been attributed as independent predictors for survival and recurrence in carcinoma of unknown primary (CUP). Objective The purpose of this study was to analyze the prognostic value of p16 overexpression for CUP in the absence of true primary (TP). Methods The study involved 43 patients who underwent therapeutic lymph node dissection (LND) from 2000 to 2015 after all the diagnostic work up for CUP. Immunohistochemistry for p16 overexpression was performed. Cox proportional hazard regression analysis was used to analyze the prognostic impact on 5-year overall survival (OS) and recurrence-free survival (RFS). Results The male-to-female ratio was 5.1:1, with a median age of 62 years. The clinicopathological data, except for p16 overexpression, did not differ significantly in terms of 5-year OS and RFS. The Cox regression analysis proposed p16 positivity to be an independent prognosticator of regional recurrence-free survival (RRFS) (hazard ratio [HR] 6.180, p = 0.21). The median time to recurrence and death were 10 and 25 months, respectively. Conclusion Cervical metastasis with p16 overexpression is a significant prognostic factor of improved RFS after surgery in CUP. The prognostic significance of lymph node p16 positivity should be further studied.

Abstract
Background: The mere memorization of isolated facts without the claim of integrating them is detrimental to the desired learning outcomes in medical education. The current study was conducted within an environment where items from summative assessments are regularly disclosed by the university and consequently collected into an item bank that is shared between students. Within this environment, we aimed to quantify 1) to which extent students use disclosed items for their preparation for the summative exam, 2) a putative mismatch between (isolated factual) knowledge regarding distinct questions from the item bank and conceptual knowledge, and 3) to which extent this mismatch can be ameliorated by a project aiming to steer student learning away from the memorization of isolated facts toward the acquisition of conceptual knowledge. Methods: This steering project in the midst of the first semester consisted of the implementation of an oral exam based on selected learning objectives, preceded by two seminars. After their summative exam at the end of semester, 135 students performed a voluntary exam for study purposes. Here, authentic (i.e., presumably preknown) physiology questions taken from the item bank were used to assess students' ability to 1) recognize the correct answer in a multiple choice (MC) question, 2) recall the answer (short answer), or 3) display conceptual knowledge closely corresponding to the question presented in the other formats. Additionally, students received a questionnaire addressing their learning habits and attitudes. Results: The median reported percentage of learning time for the summative exam exclusively spent with this item bank was 80%. The results of the voluntary exam indicate that students frequently recognize and recall correct answers of included items without displaying knowledge of the underlying concept. Compared to recall of the correct answer, the probability of giving a correct answer regarding the corresponding basal physiologic concept was lower by 47 percentage points (p <0.001) for topics not included in the steering project. Regarding topics included in the steering project, this discrepancy was reduced to 25.5% (p <0.001). Conclusion: The results of this study demonstrate the influence of disclosed items on student learning and learning outcomes and suggest that a carefully implemented assessment is able to improve conceptual knowledge in physiology.

Abstract
Mammary analogue secretory carcinomas (MASCs) of the parotid gland are considered as low-grade malignancies with good clinical outcome but lacking data regarding prognostic factors. We performed meta-analysis assessing prognostic factors for disease-free survival (DFS) and overall survival (OS) in 256 patients with MASCs of the parotid gland. A total of 73 studies have met the inclusion criteria and 76.3% of patients were seen with T1 and T2 tumors and negative neck nodes. Lymph node metastasis (57.4%) and distant recurrences (46.2%) were particularly found in T4 tumors (p < 0.001). DFS at 5 and 10 years was 77.9% and 47.2% compared to 88.1% and 77.2% for OS at the same time points. Male sex, T3-T4 tumors, and recurrent disease represented independent worse prognosticators for survival outcome. Altogether, parotid gland MASCs show good long-term outcome, but T4 tumors behave significantly more aggressive and require extended treatment strategies along with close follow-ups.

Abstract
Simple Summary Evaluation of the long-term functional outcome after primary or salvage laryngopharyngectomy. Long term functional outcome mainly depends on extent of pharyngectomy and salvage situation, which is reflected by our new classification system. Abstract (1) Objective: To evaluate long-term functional outcome in patients who underwent primary or salvage total laryngectomy (TL), TL with partial (TLPP), or total pharyngectomy (TLTP), and to establish a new scoring system to predict complication rate and long-term functional outcome; (2) Material and Methods: Between 1993 and 2019, 258 patients underwent TL (n = 85), TLPP (n = 101), or TLTP (n = 72). Based on the extent of tumor resection, all patients were stratified to (i) localization I: TL; II: TLPP; III: TLTP and (ii) surgical treatment (A: primary resection; B: salvage surgery). Type and rate of complication and functional outcome, including oral nutrition, G-tube dependence, pharyngeal stenosis, and voice rehabilitation were evaluated in 163 patients with a follow-up ≥ 12 months and absence of recurrent disease; (3) Results: We found 61 IA, 24 IB, 63 IIA, 38 IIB, 37 IIIA, and 35 IIIA patients. Complications and subsequently revision surgeries occurred most frequently in IIIB cases but rarely in IA patients (57.1% vs. 18%; p = 0.001 and 51.4% vs. 14.8%; p = 0.002), respectively. Pharyngocutaneous fistula (PCF) was the most common complication (33%), although it did not significantly differ among cohorts (p = 0.345). Pharyngeal stenosis was found in 27% of cases, with the highest incidence in IIIA (45.5%) and IIIB (72.7%) patients (p < 0.001). Most (91.1%) IA patients achieved complete oral nutrition compared to only 41.7% in class IIIB patients (p < 0.001). Absence of PCF (odds ratio (OR) 3.29; p = 0.003), presence of complications (OR 3.47; p = 0.004), and no need for pharyngeal reconstruction (OR 4.44; p = 0.042) represented independent favorable factors for oral nutrition. Verbal communication was achieved in 69.3% of patients and was accomplished by the insertion of voice prosthesis in 37.4%. Acquisition of esophageal speech was reached in 31.9% of cases. Based on these data, we stratified patients regarding the extent of surgery and previous treatment into subgroups reflecting risk profiles and expectable functional outcome; (4) Conclusions: The extent of resection accompanied by the need for reconstruction and salvage surgery both carry a higher risk of complications and subsequently worse functional outcome. Both factors are reflected in our classification system that can be helpful to better predict patients’ functional outcome.

Abstract
Background: Prolonged hospitalization after tonsillectomy up to three nights was implemented to decrease mortality due to post-tonsillectomy hemorrhage.Aims: To assess if extension of postoperative inpatient observation time from one to three nights results in potential benefits following tonsillectomy.Subjects and methods: Patients who stayed only one night post-tonsillectomy between 1994 and 2006 (Group A) were compared to 1570 patients who stayed three nights postoperatively between 2008 and 2016 (Group B). Complication rate and expense of hospitalization were compared.Results: Published data show that 114 (1.78%) out of 6400 patients in group A had post-tonsillectomy hemorrhage. In this patient group 75.4% (n = 86) of all bleedings occurred after discharge from hospital. However, in group B post-tonsillectomy hemorrhage occurred in 70 (4.5%) and of those only 0.38% (n = 6) developed bleeding episodes on the second or third postoperative day (POD). As observed in group A, the majority of hemorrhage (n = 57; 81.4%) was observed after discharge. Cost analysis reveals a difference of approximately 6 million €for all 32 ENT departments per year in Austria.Conclusions and significance: Extending postoperative hospitalization from one to three nights reveals no benefit after tonsillectomy. Comparison reveals substantial increase of costs for an extended 3 nights inpatient stay.

Abstract
OBJECTIVE The objective of this study was to determine the prognostic and predictive impact of β-catenin, TCF21 and WISP1 expression in patients with squamous cell carcinomas of the head and neck who underwent primary radiotherapy or concomitant chemoradiotherapy. STUDY DESIGN Prospective cohort study. SETTING University hospital. PARTICIPANTS Protein expression profiles of β-catenin, TCF21, WISP1 and p16 were determined by immunohistochemical analyses in tissue samples of 59 untreated patients. Expression was correlated with different outcome parameters. MAIN OUTCOME MEASURES Impact of TNM classification, grading, sex, age, gender, type of therapy, response to therapy and p16 status on disease-specific (DSS) and disease-free survival (DFS). RESULTS Patients with high expression of TCF21 were associated with significantly worse disease-specific survival (P = 0.005). In a multivariable analysis, TCF21 was a significant determinant of disease-specific survival. (HR 3.01; P = 0.036). Conversely, low expression of β-catenin (P = 0.025) and WISP1 (P = 0.037) revealed a better response to radiotherapy. CONCLUSION Since data show that TCF21 is a prognostic factor for disease-specific survival and WISP1 and ß-catenin are predictive factors for clinical outcome after definitive radiotherapy, further studies are warranted to prove these preliminary but very promising findings.

Abstract
PURPOSE Since squamous cell carcinomas (SCCs) of the nasoethmoidal complex are rare and aggressive malignancies, the purpose of this study was to evaluate whether anatomic subsites of SCCs of the nasal cavity and ethmoid sinuses affect clinical outcome. METHODS We retrospectively analyzed data from 47 patients with primary SCCs of the nasal cavity and ethmoid sinuses who were treated at the Department of Otorhinolaryngology, Head and Neck Surgery, Medical University of Vienna, between 1993 and 2018. The impact of anatomic subsites of nasoethmoidal SCCs was evaluated with respect to tumor and nodal classification, disease-free survival (DFS) and disease-specific survival (DSS). RESULTS Of the 47 cases, 17 SCCs (36.2%) originated from lateral nasal wall followed by 13 (27.7%) tumors of the edge of naris to mucocutaneous junction, 11 (23.4%) SCCs of the nasal septum, 3 tumors of the nasal floor (6.4%) and 3 SCCs of the ethmoid sinuses (6.4%), respectively. SCCs of the nasal septum were associated with significantly higher rates of neck node metastasis (p = 0.007), which represented a significantly worse prognostic factor for DSS (HR 7.87; p < 0.001). Moreover, advanced tumor stage (HR 5.38; p = 0.014) and tumor origin of nasal septum (HR 4.05; p = 0.025) were also significantly worse prognostic factors for DSS. Fourteen patients (29.8%) developed recurrent disease, including eight local (17.0%), five regional (10.6%) and one distant (2.1%) recurrence. Elective neck dissection (ND) was associated with lower (0 vs. 20.0%) but not significantly different regional and distant DFS (p = 0.075). CONCLUSION Anatomic origin of nasal SCC has significant impact on clinical outcome. SCCs of the nasal septum were associated with higher rates of positive neck nodes and worse outcome.

Abstract
Background The aim of this study was to determine the prevalence of MCPyV in Merkel cell carcinoma (MCC) primaries versus lymph node metastasis and to evaluate possible prognostic factors. Methods Samples of MCC primaries and lymph node metastases were stained immunohistochemically for the MCPyV large T-antigen and expression was compared to patients´ clinical outcome. Results 41 MCC patients were included. 33 (61%) out of 54 specimens were MCPyV-positive in the immunohistochemistry. 15 (47%) out of 32 primary tumors were positive compared to 18 (82%) out of 22 lymph node metastases. Eleven patients with positive polyomavirus expression died from the carcinoma compared to 4 patients without virus expression. Cox regression analysis showed worse disease-free survival in patients with MCPyV compared to virus-negative lymph nodes (p = 0.002). Conclusions To our knowledge this is the first study to describe a negative prognostic effect of the MCPyV expression in lymph node metastasis in MCC patients.

Abstract
Background Despite significant advances in diagnosis and therapy, the rate of survival of patients with oral cancers still remains poor as an appropriate treatment has not been found yet, due to side effects of chemo/radiotherapy. Aim This study aimed to identify molecular mechanisms of cell death of oral cancer cells caused by treatment with a nonselective Cox-2 inhibitor in combination with a low-dose chemotherapeutic drug. Methods Squamous cell carcinoma (SCC) cells SCC9 and SCC25 were subjected to mono- and combination therapy with nimesulide and cisplatin. Fluorescence-activated cell sorting (FACS), immunohistochemistry, high-pressure liquid chromatography (HPLC), microarray gene chips, and isobaric tags for a relative and absolute quantitation (iTRAQ) system were used. Results Increased numbers of apoptotic and necrotic SCC9/SCC25 cells were detected after combined exposure. ATP levels and the energy charge of SCC9 cells were significantly decreased after both individual and combined treatment. We detected and quantified a responsible gene, keratin 6a, and 540 relevant proteins. In SCC25 cells, ATP levels significantly decreased only after combination therapy. After combined treatment of SCC9 cells, significant upregulation of Histon-H2A/H2B/H4 was found, with a local discovery false rate of 0.003 for Histon-H2A and 0.0027 for Histon-H2B, respectively. Conclusion Compared to the single-drug treatment, combined treatment of the oral cancer cells with nimesulide and cisplatin increases and induces necrosis and apoptosis through different pathways. A significant effect of the cytoplasmic increase was also observed in histones of cell lines SCC9 and SCC25 that were previously treated with combined nimesulide and cisplatin therapy.

Abstract
BACKGROUND Sinonasal carcinomas are rare. The purpose of this study was for us to present our assessment of the effects of retropharyngeal lymph node involvement at diagnosis on patient outcomes. METHODS Retropharyngeal lymph node involvement in 36 patients with sinonasal carcinoma was determined by radiology at initial presentation. Clinical outcome, in particular, overall survival (OS) and locoregional control, was assessed by Kaplan-Meier analysis and log-rank testing. RESULTS Retropharyngeal lymph node involvement was associated with statistically significant decreased OS (P = .0066) in the patient collective. In the squamous cell carcinoma (SCC) subgroup (n = 23), decreased OS (P = .0046) and worse locoregional control (P = .0065) were observed. In these patients, decreased OS (P = .0423) and worse locoregional control (P = .0315) were also seen in the advanced tumor subgroup. CONCLUSION Retropharyngeal lymph node involvement at diagnosis is a significant prognostic factor for decreased OS and locoregional control in sinonasal carcinoma.

Abstract
Parotid gland tumors are a rare and heterogeneous entity. Molecular markers are sparse. The aim of the study was to identify new diagnostic markers in benign and malignant salivary tumors. A tissue microarray was constructed with 158 tumor samples. Expression of 21 tumor antigens involved in tumor cell survival and known for prognostic potential was assessed immunohistochemically in all parotid gland samples. CEA, Cox-1, Cox-2, Sigma, beta-Catenin, WISP-1 and PDGF-beta were differently regulated in benign and malignant parotid tumors. Subsequently, these seven proteins entered the step-wise logistic regression analysis. As a second step, we defined a score for differentiating benign versus malignant parotid lesions: 4*CEA+15*Cox-1+4*Cox-2+4*Sigma+3*PDGF-beta+10*beta-Catenin+14*Wisp1. Sensitivity and specificity of 94 and 83% were reached. Besides routine hematoxylin and eosin staining, definition of new diagnostic markers and subsequently a new diagnostic score are an attempt to create an additional tool for the diagnosis of parotid gland tumors.

Abstract
The anti-apoptotic protein Mcl-1 is highly expressed in various types of malignant tumors. Overexpression is reported to correlate with poor prognosis and disease progression. We report the expression levels of Mcl-1 in tumor samples of the parotid gland. A retrospective study containing 108 patients was performed. A tissue microarray of six malignancies of the parotid gland and pleomorphic adenoma as control was constructed. Parotid gland tumor samples were immunohistochemically stained for Mcl-1 and expression intensities were assessed. Statistical analysis included correlation to patients' clinical data and comparison of malignancies to the adenoma. All malignancies had significantly higher expression of Mcl-1 than the pleomorphic adenomas. The intensity, however, had no significant correlation to overall survival. Our immunohistochemical findings indicate that parotid gland malignancies produce high levels of Mcl-1 protein. Therefore, Mcl-1 might serve as a predictive co-marker in tumors of the parotid gland.

Abstract
BACKGROUND AND OBJECTIVES This retrospective study was performed to evaluate the status of p53 in pleomorphic adenomas and carcinomas ex pleomorphic adenoma in the parotid gland. As loss or mutation of p53 can cause malignant transformation, the possible degeneration of pleomorphic adenomas to carcinomas ex pleomorhic adenoma was investigated by mutational analysis. METHODS Twenty-five Patients including 14 patients with pleomorphic adenomas and 11 patients with carcinoma ex pleomorphic adenoma of the parotid gland were examined for p53 status. DNA was extracted out of paraffin-embedded tissue and PCR was performed for the coding exons 2-11. Denaturing gradient gel electrophoresis (DGGE) was carried out for mutational analysis and DNA sequencing was performed in case of a suspected mutation. RESULTS Fourteen pleomorphic adenomas and 11 carcinomas ex pleomorphic adenoma were screened for p53 status and potent mutations. Subsequent sequencing of the distinct exons showed no mutation. CONCLUSION We could not detect mutations of p53 neither in benign nor malignant parotid tumors and we therefore assume that p53 plays no role in the transformation from pleomorphic adenoma to carcinoma ex pleomorphic adenoma.

Abstract
BACKGROUND AND OBJECTIVES Measurement of circulating endothelial cells (CECs) and progenitor cells (EPCs) has potential as a surrogate marker for monitoring anticancer treatment. This study evaluated the significance of CECs and EPCs in the blood of patients with head and neck squamous cell carcinoma. METHODS In a prospective trial fresh blood samples from 22 tumor patients and 18 controls were tested using multiparametric flow-cytometry. CECs were defined as CD31(+)/CD146(+) and CD45(-)/7AAD(-). EPCs were defined as CD133(+)/KDR(+) and CD3(-)/CD19(-)/CD33(-)/7AAD(-). RESULTS Median levels (min/max) of CECs in the tumor group were 2 (0/5) at the time of diagnosis, 1 (0/5) 1 year after therapy and 2 (0/6) in the control cohort. Median levels of EPCs were 5 (1/41) before and 10 (0/21) after treatment in the tumor group compared to 2 (0/7) in the control cohort (P < 0.001 and P = 0.03). CEC and EPC levels showed no apparent correlation with tumor size and response to radiotherapy after 18 months of observation. CONCLUSIONS In this pilot study CD133(+)/KDR(+) EPCs were significantly elevated in head and neck tumor patients before and after therapy. Our results warrant further studies on the use of EPCs as a surrogate marker for anticancer therapies in these patients.

Abstract
AIMS The aim of this study was to compare laser surgery, conventional endoscopic surgery and radiotherapy in the treatment of early T1a glottic cancer. METHODS We conducted a retrospective analysis of patients with early vocal cord cancer (who underwent either conventional surgery via endoscopy or laryngofissur, or primary radiotherapy) at the Medical University of Vienna. By univariate and multivariate Cox regression models the influence of treatment and other parameters on survival and locoregional control were analysed. RESULTS 337 Patients were analyzed with a mean follow-up period of 133.8 months. Overall survival rates where similar in all three treatment groups. Five-year, 10-year and 15-year estimates of disease specific survival for laser-treated patients were 100%, for conventional surgery were 100%, 98% and 98%, and for radiotherapy were 96%, 92% and 91%, respectively. Locoregional recurrences were observed after laser surgery in 10%, after conventional surgery in 13% and after radiotherapy in 30% of the patients treated. According to the log-rank test, time to relapse was significantly shorter for irradiated patients compared to patients who underwent surgery (p < 0.0001). Mortality caused by the laryngeal tumour was significantly higher in the radiotherapy group (p = 0.003). CONCLUSION Patients undergoing laser or conventional surgery have a significantly lower incidence of locoregional recurrences and longer disease-free intervals when compared to patients treated by radiotherapy.

Abstract
Head and neck surgeons hesitate to resect the carotid artery because of the postoperative risk of neurologic sequelae. However, there is no curative therapeutic option for head and neck neoplasms involving the carotid artery, with the exception of complete tumor removal. To evaluate the benefits and risks of carotid revascularization techniques in locally advanced head and neck tumors we performed a retrospective analysis in an institutional, tertiary care medical center. Seven patients (5 males, 2 females) with a median age of 58 years underwent en bloc removal of locally advanced head and neck tumors, including carotid resection and revascularization, in the University of Vienna General Hospital, over a 15-year period. In six patients carotid reconstruction was accomplished by bypass grafting (five autologous grafts, one synthetic graft) and in one patient angiopatchplasty was used. There were no perioperative neurologic complications or deaths. Survival was > 12 months in 5/7 patients; the other 2 patients died within 6 months due to untractable progression of cancer. We conclude that carotid revascularization techniques offer the possibility of better local control for advanced head and neck tumors without additional risks of neuromorbidity or mortality.

Abstract
OBJECTIVE To describe our experience with superimposed high-frequency jet ventilation (SHFJV), which does not require any endotracheal tubes or catheters, for performing laryngeal and tracheal surgery. DESIGN A case series of 500 patients. SETTING A university medical center. PATIENTS Four hundred sixty adult patients and 40 children in a consecutive sample who required laryngeal or tracheal surgery under SHFJV. INTERVENTIONS The SHFJV uses 2 jet streams with different frequencies simultaneously and is applied using a jet laryngoscope. Ventilation was performed with an air-oxygen mixture, and intravenous agents were used for anesthesia. Arterial blood gas values were analyzed. MAIN OUTCOME MEASURES Reported values of oxygenation and ventilation during the application of SHFJV and laryngotracheal surgery. RESULTS In 497 patients, adequate oxygenation with a mean +/- SD PaO2 of 91.8 +/- 22.9 mm Hg and ventilation with a PaCO2 of 29.7 +/- 5.5 mm Hg were achieved using SHFJV. The average duration of the application of ventilation was 27 minutes, and the longest duration was 118 minutes. No complications due to the ventilation technique were observed. Laser surgery was performed in 150 patients. CONCLUSIONS The use of SHFJV in combination with the jet laryngoscope provides patients with sufficient ventilation during laryngotracheal surgery. Even in patients at high risk because of pulmonary or cardiac disease, this technique can be applied safely. In patients with stenosis, the ventilation is applied from above the stenosis, reducing the risk of barotrauma. The SHFJV can be used for tracheobronchial stent insertion, and laser can be used without any additional protective measures.

Abstract
Since 1983, 90 autologous jejunal transplantations for reconstruction of the upper digestive tract have been performed in 89 patients (9 females, 80 males, average age 56.3 years). 73 patients were operated primarily, in 16 patients a recurrent tumor had been treated. One patient received a second jejunal graft after necrosis. In these heterogenous patients, the primary tumor was located in the hypopharynx 48 times, in the larynx 21 times, in the oropharynx 19 times and twice in the oral cavity. There was nearly always tumor stage III or IV without distant metastases. Following locoregional tumor resection, speech restoration was achieved 35 times by a siphon-like tube, and the upper digestive tract was reconstructed using a patch 18 times and by a tube 28 times. A combination of tube or patch with a siphon-like tube was employed 9 times. In only two of 16 patients with recurrent tumor, speech reconstruction was performed, in the other 14, the upper digestive tract was reconstructed. In those patients, in whom speech reconstruction (by siphon tube or by combination with tube/patch) was intended, this was achieved in 81.5%. Successful functional reconstruction of the upper digestive tract (by patch, tube, combination) could be achieved in about 60% of these patients.

Abstract
We present the first use of tubeless superimposed combined high- and low-frequency jet ventilation (SHFJV) with a jet laryngoscope in laryngotracheal surgery in infants and children. Twenty-eight patients underwent 53 operative procedures. The average age of the patients was 7.3 years. The most common diagnoses were laryngeal papillomatosis and subglottic stenosis. The duration of jet ventilation averaged 33 min. The gas exchange was sufficient in each case. The advantages of SHFJV in the surgery of the laryngotracheal area in infants and children are optimal view at the larynx and trachea, maximum space for the handling, application of the laser without risks, no time limitation, suitability for stenosis, and neither anesthetic nor surgical complications.

Abstract
In laryngectomized patients a tracheo-esophageal artificial fistula can be used to achieve air flow from the trachea to the esophagus during speech. A one-way plastic valve is often used for the fistula. A free jejunal graft between the trachea and the esophagus can also be used. To avoid aspiration the transplant is attached to the submental area giving the graft a siphon-like shape. We performed 23 videoradiographic examinations using high-density barium in 14 such patients. The aim was to evaluate the protective function of these grafts against aspiration. Penetration of the bolus and a small amount of residual contrast material in the ascending limb of the graft was a normal finding. If the standard barium bolus reached the descending limb at any time during the examination, this was a sign of aspiration hazard. To avoid aspiration, the vertex of the speech siphon should be higher than the level of the hypopharyngeal anastomosis.

Abstract
In a 35-year old male patient with laryngeal carcinoma an acute respiratory insufficiency with early hypoxaemia developed due to massive laryngeal stenosis. An endotracheal intubation was not possible since the available lumen was too small. Tracheotomy using local anaesthesia was not possible since spontaneous respiration with a Venturi mask applying 100% oxygen was not sufficient and the patient was becoming restless and agitated due to the hypoxaemia. Transcutaneous jet ventilation was considered to be too risky since the needle would have to pass highly vascularised tumour tissue and the detection of such a small rest lumen would have been quite difficult. Ventilating the patient using a percutaneous catheter would have been very risky as well since, due to the massive stenosis, a sufficient expiration would not be likely and therefore was considered to carry a high risk of barotrauma. The patient was ventilated under general anaesthesia via a specially designed endoscopy tube with integrated jet nozzles applying superimposed high frequency jet ventilation above the stenosis. Since it was possible to achieve sufficient ventilation during the inspection of the larynx the jet laryngoscope was left in place and the supporting apparatus was covered with sterile drapes. The tracheotomy was performed using the superimposed high frequency jet ventilation. Throughout the procedure oxygenation and ventilation were adequate. The laryngectomy performed several days later revealed a cauliflower type protrusion into the tracheal lumen and a 5 cm long stenosis of the larynx with a lumen of 3 mm.

Abstract
In laser surgery of the larynx the surgeon and the anaesthesist have to compete for the limited space available. The surgeon requiring good visibility and an undisturbed operating area whereas the anesthetist has to ensure sufficient ventilation of the patient. Further, complications of anaesthesia and laser must be avoided. These requirements are met by using the jet-tube (jet-laryngoscope) with two integrated nozzles applying simultaneously low- and high-frequency jet-ventilation giving the surgeon total access to the area operated on, and at the same time enables safe ventilation of the patient. Of 334 operations with the tubeless ventilation technique 76 cases were laser surgical interventions. In 6 patients stenoses were enlarged. The average duration of the jet-ventilation was 25 +/- 10 minutes. The maximum duration of a laser surgical intervention was 140 minutes. The age distribution of the patients was 18 months to 82 years. In all patients pulmonary gas exchange was satisfactory. We believe that the advantage of the tubeless jet-ventilation is: optimal visibility and surgical freedom for the surgeon, no time limitation, even in very severe stenoses. Since no volatile anaesthetics or any type of endotracheal tube are applied there is no danger of interaction with the laser when using the SHFJV via the jet-laryngoscope. Application of the tubeless jet-ventilation technique is however limited if patients suffer from severe pulmonary obstruction; likewise highly obese patients and patients in whom massive bleeding occurs are not amenable to tubeless jet-ventilation.

Abstract
The tendon of the human stapedius muscle was studied in normal post mortem material and in clinical otosclerotic patients, using light and electron microscopy. Cross section profiles of collagen fibrils were measured in various regions of the tendon and the amount of elastin was estimated. The normal stapedius tendon consisted of three concentrically arranged portions: A cylindrical central part, a tube-like mid-portion, and a cortical layer. The central part was made up of collagen fibrils with only a few elastic fibers, the mid-portion contained collagen fibrils together with significantly more elastic material, while the cortical layer, again, showed a smaller amount of elastic fibers. Mean diameters of collagen fibrils in the central part of the tendon were 65.12 +/- 11.89 nm, in the intermediate layer 41.00 +/- 9.63 nm, and in the cortical layer 70.28 +/- 19.58 nm. Stapedius tendons from clinically otosclerotic patients, though showing the same construction, were characterized by significantly altered collagen fibrillar diameters (Mann-Whitney U-test). In the central part, mean diameters were reduced to 61.05 +/- 14.70 nm, in the mid-portion increased to 50.90 +/- 10.08 nm, and in the cortical layer reduced to 61.09 +/- 8.49 nm. The changes of collagen cross section profiles estimated for the entire tendon were significant as well: 59.68 +/- 18.74 nm in controls versus 57.82 +/- 12.53 nm in otosclerotic patients. Elastin content in the mid-portion of control stapedius tendons increased with age (13% at 35 years of age to 35% at 70 years of age).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In this article, we report about the experiences at our ENT-University Clinic in Vienna in 76 patients with free transplanted microvascularly anastomosed autologous jejunum used for reconstruction following extensive resection of mainly stage IV carcinomas in the head and neck. Jejunum was inserted as a siphon-like tube between the trachea and the hypopharynx in 43 patients primarily for restoration of speech (in 10 cases the pharynx was also reconstructed). In 33 patients, the upper digestive tract was reconstructed, as either patch or tube. They were then evaluated according to functional results of speech and swallowing, aesthetics as well as 5-year survival rates. We achieved good results in 35 speech patients (81.4%) and in 22 swallowing patients (66.6%). The aesthetic function was influenced favourably because the volume of the jejunal transplant fills up the defect in the neck after resection and creates a tolerable neck-shape. The 5-year survival of all available 54 patients was 26%, patients for speech restoration 31.7% and patients for swallowing restoration 17.5%. These results are to be considered under the aspect that patients with swallowing restoration primarily had more severe disease. Complications such as like perioperative mortality and total necrosis can be avoided by careful evaluation of the patients to be operated on. With the experiences gained from this study, we now have exact indications for the use of jejunum grafts and thus can expect very high rates of success.

Abstract
The expressions and cellular distributions of two pairs of adhesion molecules CD2/LFA-3 (leukocyte function-associated antigen-3) and LFA-1/ICAM-1 (intercellular adhesion molecule-1) were examined in inflammatory cellular infiltrates of advanced squamous cell carcinomas of the head and neck by immunohistochemical techniques including double-staining methods. Thirteen patients were investigated using the following monoclonal antibodies (mAbs): CD2, LFA-3 (CD58), ICAM-1 (CD54), LFA-1 (CD11a), the alpha/beta and gamma/delta T-cell receptor, pan T cells and broadly distributed monocyte/macrophage (m/m phi) [Fc gamma RII (CD32), 25F9, RM3/1]. LFA-3 staining was observed on a high number of cells (968 +/- 112 cells/mm2), correlating to the number of Fc gamma RII (CD32; P < 0.01), 25F9 (P < 0.05) and RM3/1 (P < 0.05) positive m/m phi. Its ligand CD2 was found on 365 +/- 126 cells/mm2, representing about 50% of CD3+ cells (730 +/- 286 cells/mm2). CD2 positivity correlated to CD3 and CD8 (P < 0.01) but not to CD4+ T cells. LFA-1 and ICAM-1 were expressed on lymphocytes as well as on m/m phi. ICAM-1+ cells (902 +/- 205 cells/mm2) correlated to CD3+, CD8+ and RM3/1+ cells (P < 0.01). LFA-1 positivity (803 +/- 255 cells/mm2) showed correlations to nearly all investigated antigens, as well as to CD4+ T cells (P < 0.05). These results show that different m/m phi subsets display distinct patterns of adhesion molecule expressions suggesting different pathways of regulation. The CD3+ lymphocyte population revealed a lack of CD2 expression that was more pronounced in the CD4+ subset and indicated impaired lymphocyte function.

Abstract
The effect of free transplanted jejunum autografts, inserted after resection of extensive squamous cell carcinoma of the larynx and hypopharynx is evaluated in terms of survival and the development of local and regional recurrences. In a matched-pair analysis, 22 patients with jejunum transplants were compared with 44 patients with the same performance status, in whom after laryngopharyngectomy, the pharynx had been closed with local mucosa. The cumulative survival rate was calculated using the Kaplan-Meier method; the statistical comparison of the survival curves of the two groups was made with the Mantel-Haezel test. Patients of the study group had a statistically significant (p less than = 0.01) better survival rate than those of the control group, the 50% survival rate being 36 and 11 months, respectively. Local recurrences occurred in 9.1% of the patients in both the study group and in controls, and regional recurrences in 40.8 and 43.2%, respectively. This militates against the possibility that the surgery in patients in whom reconstruction with jejunum was possible might have been more radical. Further, it may be speculated that the statistically significant better survival rate is due to the jejunum itself, presumably to a tumourprotective effect of the lymphatic tissue of the transplant.

Abstract
Autologous jejunum, transplanted as a functional replacement immediately after radical dissection of advanced stages of squamous cell carcinomas of the head and neck and subsequently irradiated, was examined by immunohistochemistry (APAAP/PAP-technique). Biopsies from 9 patients were taken at the time of transplantation and up to 24 months thereafter (group 1) and from 5 patients only once after transplantation (group 2). Twenty-six monoclonal antibodies (mAbs) were used as surface markers to give an overview about phenotypical changes with respect to T-, B- and M phi-antigens. 1) B cells: a general increase of CR2+ (CD21, p less than 0.01) could be noticed after transplantation, immunoglobulin positive cells remained unchanged expect for a significant decrease of IgM+ (p less than 0.01) and IgA1+ (p less than 0.01) cells. 2) The number of T cells (CD3+) showed no significant differences although TcR gamma/delta+ cells decreased (p less than 0.01) in the autotransplant. ICAM-1 (CD54) and IL-2R (CD25) were found on a significant (p less than 0.01) higher number of cells after transplantation. 3) Cells with M/M phi morphology showed increased expression of the Fc gamma receptors (CD64, p less than 0.001; CD32, n.s.; CD16, p less than 0.001), of the complement receptors CR1 (CD35, (p less than 0.001) and CR3 (CD11b, p less than 0.02), of HLA-DQ (p less than 0.01), and of the antigens 25F9 (mature M phi; p less than 0.01) and CD4 (p less than 0.02). Correlation analyses of data obtained from the biopsies of the 14 autotransplanted jejunum cases revealed a CD35+ and a 25F9+ subpopulation of M/M phi. Our findings indicate that despite irradiation autotransplanted jejunum contained cells with immunological capacities. Therefore, the replacement of larynx by autologous jejunum may facilitate not only mechanical but also immunological functions.

Abstract
For surgical voice rehabilitation after pharyngolaryngectomy we use the technique of placing a siphonlike jejunal interposition in order to create a tracheohypopharyngeal shunt. In this paper we present the functional benefits of this method of voice rehabilitation. The best results achieved are compared with a normal voice using the following test parameters: electroacoustic sound analyses and voice status. The findings show that the siphon voice is adequate for everyday purposes and can achieve useful social verbal communication.

Abstract
After the reconstruction of defects resulting from the resection of advanced tumors from the upper aerodigestive tract using free microvascular anastomized jejunum, the autotransplant is influenced by local radiotherapy (cumulative dose 50-70 Gray). Biopsies were taken from 15 patients, stained with haemotoxilin-eosin and Giemsa and compared by means of light microscopy with jejunum taken at the time of transplantation. It was possible to observe a widened mucosal and submucosal space two to three months after radiotherapy, similar to the clinical impression of a radiogenic enteritis. The villi were flat and shortened with no or slight epithelial lesions. Additionally, it was possible to observe an inflammatory infiltration consisting mainly of neutrophilic granulocytes, edemas, and telangiectases. The latter were also evident in nonirradiated autotransplanted jejunum and are therefore not only caused by irradiation. One year after radiotherapy the mucosal membrane was atrophic. Fibrosis was to be seen in the lamina propria, accompanied by widened muscularis mucosae. The submucosal space was also widened and fibrotic to a varying degree. It was possible to detect varying stages of alteration in the vascular system up to a complete obliteration. After two years, changes were more pronounced. At no time could any alteration in the nervous system of the plexus submucosus be observed. All of these changes have to be interpreted as a consequence of irradiation. However, lubrication of the mucosal surface and the motility of the transplant are not altered severely by irradiation and therefore the desired functions of the free transplanted jejunal grafts, such as swallowing and phonation, are carried out sufficiently.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
UNLABELLED The influence of smoking with regard to the development and course of laryngeal dysplasias was examined. The case histories of 63 patients with histologically proven dysplasias of the larynx were evaluated in the light of their answers to a questionnaire covering their lifetime smoking habits. RESULTS 1. The percentage of smokers in the patient group significantly exceeds the percentage of smokers in the general population. 2. The disease is more likely to lead to deteriorated histological findings in smokers. 3. A change in smoking habits at the time of diagnosis has no significant effect on the further course of disease. 4. Non-smokers have higher levels of dysplasia at first biopsy, but the disease is less likely to progress. The development of malignancy was not observed in the non-smoker group.

Abstract
In this retrospective study the value of sonography in the preoperative staging of malignant tumours of the tonsils was evaluated in 36 patients. According to our results sonography is indicated in small tumours. In greater tumours, especially if bone destruction could be expected, MR or CT should be performed additionally to sonography. Good results were achieved in assessing the infiltration of the tongue with or without crossing the midline (accuracy 92 to 97%) and the detection of cervical lymph node metastasis (accuracy 94%).

Abstract
The significance of tobacco smoking, alcohol consumption and occupation as risk factors for the development of vocal chord dysplasia was evaluated in a case-control study. Twenty-seven male patients with dysplasia of the vocal chords were chosen from the I. ENT-University Clinic in Vienna (1985-1988) and compared with 54 controls. The main results are: The relative risk (RR) of a smoker compared to that of a non-smoker for vocal chord dysplasia is 7.27 (6.81-7.73); the RR adjusted for occupation is 3.58 (2.31-4.84). The most important risk factor, however, is occupational exposure. The relative risk of a blue collar worker compared to that of a white collar worker is 11.04 (10.61-11.46), which is reduced only to 10.02 (10.61-11.46) after stratification according to smoking habits.

Abstract
Knowledge of invasion of the walls of the cervical vessels by tumor is of great clinical importance before surgery. We performed sonography on 83 patients with palpable cervical lymph node metastases in the region of the carotid bifurcation to determine the relationship of the metastases to the carotid artery and jugular vein. In all patients, the sonographic results were proved by surgery. The wall of the carotid artery was hypo-echogenic in 11 of 12 patients with surgically proved tumor invasion of the artery. Four results were false-positive. Palpation or swallowing during real-time scanning showed mobility of the tumor relative to the wall of the artery in 47 patients (57%). In these patients, tumor invasion could be excluded. Bilateral compression or invasion of the internal jugular vein was identified correctly with sonography in all five patients in whom this was confirmed surgically. These results suggest that real-time sonography is a valuable method for determining the relationship between cervical lymph node metastases and the carotid artery and jugular vein.

Abstract
We compared the preoperative ultrasound findings with the histological results of 127 neck dissections for squamous cell carcinoma of the head and neck. We checked several sonomorphological criteria (size, shape, boundary, echo structure, arrangement, mobility) to assess their value in identification of metastatic disease. If all nodes found on ultrasound were classed as metastases, the specificity was 30%, because many lymph nodes showed nonspecific reaction only. Lymph nodes with a rupture of the capsule or central necrosis or being larger than 3 cm, proved to be metastatic in all cases. Round or oval nodes with a size of more than 2 cm were found to be metastatic with an accuracy of 89%. The almost certain (97%) identification of necks with no metastatic lymph nodes allows elective neck dissection to be avoided.

Abstract
The role of sonography in evaluation of tumorous infiltrations of the wall of the cervical arteries is discussed upon 75 patients with histologically proved lymphnode metastasis. Direct signs for the infiltration--loss of the echogenic wall of the arteries and indirect signs--length and circumference of the tumor/vessel contact area are evaluated. In 9 patients the infiltrations were correctly diagnosed, 4 patients were false positive. The technic of the sonographic investigation and potential pitfalls are demonstrated. The role of other investigation modalities are discussed.

Abstract
A 39-year-old patient with an epiglottic carcinoma stage T4N2M0 was treated initially by radiotherapy, but later underwent laryngectomy for irradiation necrosis. A pharyngeal fistula occurred in the irradiated area. After resection of the damaged skin reconstruction was performed by a double skin paddle myocutaneous pectoralis major flap. A recurrence of the fistula in the same area was closed by invagination of the flap. Three years later a massive scar stenosis developed in the reconstructed hypopharynx, so that the patient was unable to swallow. This required a total resection of the scar tissue which extended from the entrance of the hypopharynx to the upper oesophageal sphincter. The gap was bridged by a free microvascular jejunal graft. To date 6 months have elapsed since this operation and the patient is symptom free.

Abstract
Report on a woman patient, 69 years of age, suffering from a recurrent extensive basalioma of the external ear that was considered inoperable, as the tumour had invaded the petrous bone, the parotid gland, the mandibular joint, and the adjacent nerves. Because of unbearable pain it was decided to perform a radical operation with resection of the tumour, the petrous bone, the parotid gland, the ascending mandibular branch, the facial nerve, and part of the oral mucous membrane. The exposed large cervical vessels, dura mater, and the bony skull--of which the periosteum had to be removed--were primarily covered with a large pectoral muscle island flap and an occipital advanced flap. Twenty-four months after surgery the patient had no relapse and was free from pain.

Abstract
We report 10 patients undergoing pharyngo-laryngectomy in whom the pharyngeal defect was reconstructed with a free jejunal graft. This method is technically demanding. The advantages are excellent healing due to the excellent blood supply of the edges of the graft, and the almost unlimited supply of jejunum. The use of this method is justified by the immediate restoration of deglutition.

Abstract
16 operatively and histologically proven branchiogenic cysts were evaluated sonographically and the contents of some of them were analysed by microscopy and chemistry. The echographic appearance of all cysts depended on the frequency of the scanheads and ranged from cystic (3.0 MHz) via semi-solid (5.0 MHz) to solid (7.5 MHz). This frequency-related sonographic pattern is caused by the high amount of cholesterin contained in these cysts and permits diagnosis of a branchiogenic cyst.
