Extended partial laryngectomy with functional preservation using the rotational crico-thyrotracheopexy.

Objectives: Glottic tumors with infiltration of the anterior/posterior commissure, and lesions with subglottic, cricoid, or cricoarytenoid joint infiltration have been highly controversial in the past, from the perspective of oncological safety. Although conservation laryngeal resection options exist, most are limited by the extent of resection proscribed by the technique and the postoperative functional results. Oncologically speaking, extended vertical hemilaryngectomy is often the optimal solution. However, limited reconstruction methods often compel total laryngectomy. Methods: Eight patients with vocal fold malignancy, which infiltrated the anterior and sometimes the posterior commissure and with subglottic extension and resultant uni/bilateral vocal fold motion impairment, were treated by single stage extended vertical partial laryngectomy with rotational crico-thyrotracheopexy as a functional reconstruction of the laryngeal framework. Patients were evaluated with objective and subjective function tests. Results: Histologic examination demonstrated tumor-free margins in every case. Definitive decannulation was successful in all cases within 2 weeks. All patients had a stable and adequate airway during follow-up and reported socially acceptable voice. Oral feeding was possible in seven patients. Conclusion: Rotational crico-thyrotracheopexy, as a single stage reconstruction technique, is based on well-vascularized, readily available, appropriately shaped local tissues, without significant donor site morbidity or need for long-term stenting to reconstruct large laryngeal defects after extended vertical hemilaryngectomy for advanced unilateral glottic tumors and is applicable even with supra/subglottic invasion or infiltration of the contralateral vocal fold. An adequate airway can be achieved with socially acceptable voice and safe swallowing without compromising oncologic reliability. Level of Evidence: 4 (retrospective case series review).

Impact of a Targeted Project for Shortening of Imaging Diagnostic Waiting Time in Patients with Suspected Oncological Diseases in Hungary.

Background and Objectives: Medical imaging is a key element in the clinical workup of patients with suspected oncological disease. In Hungary, due to the high number of patients, waiting lists for Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) were created some years ago. The Municipality of Budapest and Semmelweis University signed a cooperation agreement with an extra budget in 2020 (HBP: Healthy Budapest Program) to reduce the waiting lists for these patients. The aim of our study was to analyze the impact of the first experiences with the HBP. Material and Methods: The study database included all the CT/MRI examinations conducted at Semmelweis University with a referral diagnosis of suspected oncological disease within the first 13 months of the HBP (6804 cases). In our retrospective, two-armed, comparative clinical study, different components of the waiting times in the oncology diagnostics pathway were analyzed. Using propensity score matching, we compared the data of the HBP-funded patients (n = 450) to those of the patients with regular care provided by the National Health Insurance Fund (NHIF) (n = 450). Results: In the HBP-funded vs. the NHIF-funded patients, the time interval from the first suspicion of oncological disease to the request for imaging examinations was on average 15.2 days shorter (16.1 vs. 31.3 days), and the mean waiting time for the CT/MRI examination was reduced by 13.0 days (4.2 vs. 17.2 days, respectively). In addition, the imaging medical records were prepared on average 1.7 days faster for the HBP-funded patients than for the NHIF-funded patients (3.4 vs. 5.1 days, respectively). No further shortening of the different time intervals during the subsequent oncology diagnostic pathway (histological investigation and multidisciplinary team decision) or in the starting of specific oncological therapy (surgery, irradiation, and chemotherapy) was observed in the HBP-funded vs. the NHIF-funded patients. We identified a moderately strong negative correlation (r = -0.5736, p = 0.0350) between the CT/MR scans requested and the active COVID-19 case rates during the pandemic waves. Conclusion: The waiting lists for diagnostic CT/MR imaging can be effectively shortened with a targeted project, but a more comprehensive intervention is needed to shorten the time from the radiological diagnosis, through the decisions of the oncoteam, to the start of the oncological treatment.

Longitudinal Analysis of Amplitude-Integrated Electroencephalography for Outcome Prediction in Hypoxic-Ischemic Encephalopathy.

OBJECTIVE: To investigate the prognostic accuracy of longitudinal analysis of amplitude-integrated electroencephalography (aEEG) background activity to predict long-term neurodevelopmental outcome in neonates with hypoxic-ischemic encephalopathy (HIE) receiving therapeutic hypothermia. STUDY DESIGN: This single-center observational study included 149 neonates for derivation and 55 neonates for validation with moderate-severe HIE and of gestational age ≥35 weeks at a tertiary neonatal intensive care unit. Single-channel aEEG background pattern, sleep-wake cycling, and seizure activity were monitored over 84 hours during therapeutic hypothermia and rewarming, then scored for each 6-hour interval. Neurodevelopmental outcome was assessed using the Bayley Scales of Infant Development, Second Edition. Favorable outcome was defined as having both a Mental Development Index (MDI) score and Psychomotor Development Index (PDI) score ≥70, and adverse outcome was defined as either an MDI or a PDI <70 or death. Regression modeling for longitudinal analysis of repeatedly measured data was applied, and area under the receiver operating characteristic curve (AUC) was calculated. RESULTS: Longitudinal aEEG background analysis combined with sleep-wake cycling score had excellent predictive value (AUC, 0.90; 95% CI, 0.85-0.95), better than single aEEG scores at any individual time point. The model performed well in the independent validation cohort (AUC, 0.87; 95% CI, 0.62-1.00). The reclassification rate of this model compared with the conventional analysis of aEEG background at 48 hours was 18% (24 patients); 14% (18 patients) were reclassified correctly. Our results were used to develop a user-friendly online outcome prediction tool. CONCLUSIONS: Longitudinal analysis of aEEG background activity and sleep-wake cycling is a valuable and accurate prognostic tool.

Functional results of endoscopic arytenoid abduction lateropexy for bilateral vocal fold palsy.

PURPOSE: Endoscopic arytenoid abduction lateropexy (EAAL) is a reliable surgical solution for the minimally invasive treatment of bilateral vocal fold palsy (BVFP), providing a stable airway by the lateralization of the arytenoid cartilages with a simple suture. The nondestructive manner of the intervention theoretically leads to higher regeneration potential, thus better voice quality. The study aimed to investigate the respiratory and phonatory outcomes of this treatment concept. METHODS: 61 BVFP patients with significant dyspnea associated with thyroid/parathyroid surgery were treated by unilateral EAAL. Jitter, Shimmer, Harmonics to Noise Ratio, Maximum Phonation Time, Fundamental frequency, Voice Handicap Index, Dysphonia Severity Index, Friedrich's Dysphonia Index, Global-Roughness-Breathiness scale, Quality of Life, and Peak Inspiratory Flow were evaluated 18 months after EAAL. RESULTS: All patients had a stable and adequate airway during the follow-up. Ten patients (16.4%) experienced complete bilateral motion recovery with objective acoustic parameters in the physiological ranges. Most functional results of the 13 patients (21.3%) with unilateral recovery also reached the normal values. Fifteen patients (24.6%) had unilateral adduction recovery only, with slightly impaired voice quality. Eleven patients (18.0%) had false vocal fold phonation with socially acceptable voice. In 12 patients (19.7%) no significant motion recovery was detected on the glottic level. CONCLUSION: EAAL does not interfere with the potential regeneration process and meets the most important phoniatric requirements while guaranteeing the reversibility of the procedure-therefore serving patients with transient palsy. Further, a socially acceptable voice quality and an adequate airway are ensured even in cases of permanent bilateral vocal fold paralysis.

Combined Simultaneous Multiportal Approach via Minimally Invasive Transciliary and Endoscopic Endonasal Approaches for Tumors Invading Both the Skull Base and the Sinonasal Area.

BACKGROUND: A combined transcranial and transfacial approach has long been the gold standard for surgical management of large tumors with sinonasal and skull base involvement. The extended endoscopic endonasal approach for such pathologies has its advantages, but it has flaws as well, such as anatomic limitations and more ponderous skull base reconstruction and thus higher risk of postoperative complications. Our primary technique for surgical treatment of these pathologies has been a combination of transfacial and minimally invasive transciliary supraorbital keyhole approaches. With the aim to further minimize invasiveness, potential complications, and unsatisfactory aesthetic outcomes during surgical treatment of large tumors invading both the sinonasal area and the skull base, we abandoned the transfacial approach and simultaneously combined the transciliary supraorbital keyhole approach with the endoscopic endonasal approach. METHODS: The well-known microscope-assisted minimally invasive approach via a transciliary supraorbital keyhole craniotomy was combined with the endoscopic endonasal approach. RESULTS: Six patients with different histologic types of tumors affecting the sinonasal area and the skull base were operated on. The mean operative time was 3 hours, there were no unexpected intraoperative or postoperative complications, and total tumor removal was achieved in each patient. None of the patients experienced complications associated with the surgery during follow-up. CONCLUSIONS: Our combined simultaneous multiportal approach enables total tumor eradication with reduced operative time and is associated with minimal intraoperative and postoperative complications, low mortality rate, and excellent cosmetic results.

A Randomized Controlled Study of Low-Dose Hydrocortisone Versus Placebo in Dopamine-Treated Hypotensive Neonates Undergoing Hypothermia Treatment for Hypoxic-Ischemic Encephalopathy.

OBJECTIVE: To investigate whether hydrocortisone supplementation increases blood pressure and decreases inotrope requirements compared with placebo in cooled, asphyxiated neonates with volume-resistant hypotension. STUDY DESIGN: A double-blind, randomized, placebo-controlled clinical trial was conducted in a Level III neonatal intensive care unit in 2016-2017. Thirty-five asphyxiated neonates with volume-resistant hypotension (defined as a mean arterial pressure [MAP] < gestational age in weeks) were randomly assigned to receive 0.5 mg/kg/6 hours of hydrocortisone or placebo in addition to standard dopamine treatment during hypothermia. RESULTS: More patients reached the target of at least 5-mm Hg increment of MAP in 2 hours after randomization in the hydrocortisone group, compared with the placebo group (94% vs 58%, P = .02, intention-to-treat analysis). The duration of cardiovascular support (P = .001) as well as cumulative (P < .001) and peak inotrope dosage (P < .001) were lower in the hydrocortisone group. In a per-protocol analysis, regression modeling predicted that a 4-mm Hg increase in MAP in response to hydrocortisone treatment was comparable with the effect of 15 µg/kg/min of dopamine in this patient population. Serum cortisol concentrations were low before randomization in both the hydrocortisone and placebo groups (median 3.5 and 3.3 µg/dL, P = .87; respectively), suggesting inappropriate adrenal function. Short-term clinical outcomes were similar in the 2 groups. CONCLUSIONS: Hydrocortisone administration was effective in raising the blood pressure and decreasing inotrope requirement in asphyxiated neonates with volume-resistant hypotension during hypothermia treatment. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02700828.

[Minimally invasive treatment of postintubation stenosis by use of Ultra Dream Pulse Laser and steroid-mitomycin in a 4-year-old girl]. / Postintubatiós stenosis minimálinvazív mutéti megoldása 4 éves gyermeken ultrapulzációs lézer és szteroid-mitomicin alkalmazásával.

Postintubation stenosis is a frequent complication of long-term endotracheal anesthesia. In the last few decades, its incidence showed an increasing tendency particularly among children and premature infants. It mostly affects the subglottic area and avoidance of a tracheotomy could lead to better life quality of the patient. We present the treatment of a glotto-subglottic stenosis in a 4-year-old girl. Ultra Dream Pulse Laser surgery was performed with mometason (Elocom) and mitomycin (Mitomycin-C) submucosal injections to prevent refibrosis. Minimally invasive operations play a key role in the treatment of laryngotracheal stenosis. Ultra Dream Pulse Laser surgeries could be safely applied in pediatric patients. Patient follow-up revealed wide glottis without any fibrosis. Ultra Dream Pulse Laser intervention completed with steroid-mitomycin infiltration is an efficient method of treating postintubation stenosis. Orv Hetil. 2019; 160(20): 792-796.

[Application of modified Weerda laryngoscopes in the ear, nose, and throat practice]. / Módosított Weerda-laringoszkópok alkalmazási területei a fül-orr-gégészeti gyakorlatban.

Microscope-assisted direct endoscopy of the airways and the upper gastrointestinal tract in general anesthesia is an essential diagnostic and therapeutic method of otorhinolaryngology. The quality of surgical exploration is a key for the good visibility and maneuverability of microsurgical tools. Beside the most commonly used Kleinsasser laryngoscope, the distending Weerda laryngoscope is a more favorable option for the exploration of the retrocricoid region. Narrow anatomical situation, examination and manipulation of lesions involving several sub-regions of the hypopharynx or larynx may be problematic in some cases even with this endoscope. The authors present the application of modified Weerda laryngoscopes with asymmetric spatula length in addition with four cases. The retrocricoid region, the distal part of the posterior hypopharyngeal wall and the proximal part of the esophagus can be easily visualized with this device. The modifications allow the introduction of new surgical techniques by increasing the number of applied microsurgical devices and their maneuverability. Orv Hetil. 2019; 160(7): 264-269.

Glottic configuration changes and outcomes of endoscopic arytenoid abduction lateropexy.

INTRODUCTION: Endoscopic arytenoid abduction lateropexy (EAAL) is an effective glottis enlarging procedure for the treatment of bilateral vocal cord palsy (BVCP). The postoperative glottic configuration changes can be evaluated by modern, high-resolution, 3D image reconstructions. Functional results are described by spirometry as well as objective and subjective phoniatric tests. METHODS: Unilateral EAAL was performed in ten malignant thyroid gland tumor patients (eight women, two men), who had BVCP after thyroid surgery. Slicer 3D® software was used for morphometric analysis. Pre- and postoperative peak inspiratory flow (PIF) and standard phoniatric parameters were compared. RESULTS: The glottic gap improved significantly (+ 60%). Significant improvement of PIF was found in all cases. Phoniatric tests revealed better quality of voice and patient satisfaction. Their voices changed from a severely impaired to a socially acceptable, almost normal, quality. CONCLUSION: The results support our clinical observations that the ideal position of the lateralization sutures is the one which provides a physiological abduction position of the arytenoid cartilage. Considering these good results, the surgical indications for minimally invasive endoscopic arytenoid lateropexy may be extended.

[Effectiveness of trimetazidine prolong in stable coronary artery disease. Multicenter, prospective, observational study, ONECAPS study]. / Stabil coronariabetegség kezelésére alkalmazott trimetazidin prolong hatásosságának vizsgálata. Multicentrikus, prospektív, obszervációs, nyílt klinikai vizsgálat, ONECAPS-vizsgálat.

INTRODUCTION: The effectiveness of the manegement of stable coronary artery disease among outpatients is not well known. AIM: The aim of the study was to evaluate the effect of daily once trimetazidine prolong 80 mg on the angina number and severity (Canadian Cardiovascular Society class). METHOD: This multicenter, prospective, observational, 3-month clinical study included 2160 patients, but only 1701 patients completed the study. The patients' mean age was 68 years (17% under 60 years). The start of angina was 7.8 ± 6.7 years. Hypertension (93.4%) and hypercholesterolemia (81%) were very common. RESULTS: The patients were well treated with beta-blocking agents (88%), calcium antagonists (49%), angiotensin-converting enzym inhibitors (90%) and statin (77%) but only 5% received ivabradine and 50.5% was treated with trimetazidine MR. The patients attended 3 visits (inclusion, 1 month, 3 month). During the 3-month period, the weekly angina number of all patients treated with trimetazidine prolong 80 mg decreased from 2.55 to 0.41 (p<0.0001). A favorable effect was observed in CCS grading: CCS I. from 40.37% to 66.81%, CCS II. from 49.89% to 30.59%, CCS III. from 9.17% to 2% and CCS IV. from 0.56% to 0%. The mean office measured blood pressure decreased from 137/83 mmHg to 130/80 mmHg and the heart rate from 74 bpm to 71 bpm. CONCLUSIONS: In the real-life, in the stable coronary artery disease the angina remains despite the medical treatment. Once a day administered trimetazidine prolong 80 mg significantly reduced the weekly number of angina and the severity, too. These beneficial effects mediated not only by antiischemic effect but also by increased medication adherence. Orv Hetil. 2018; 159(38): 1549-1555.

The treatment of pseudoaneurysms with flow diverters after malignant otitis externa.

Background We report a case of bilateral malignant otitis externa complicated with bilateral petrous internal carotid artery pseudoaneurysms and their successful treatment with a flow diverter. Case report A 68-year-old woman with serious complications of type II diabetes mellitus had malignant otitis externa on the right side. She was treated with combined antibiotic therapy and underwent mastoidectomy for mastoiditis. She presented at our hospital with acute hemorrhage from the right external auditory canal. The emergency computed tomography (CT) angiography revealed a multiobulated pseudoaneurysm at the petrous segment of the right internal carotid artery. The pseudoaneurysm was treated with a 5 × 40-mm Surpass flow diverter. Three months later, she developed a malignant external otitis on the left side. As the infection progressed, a left-sided mastoiditis, a brain abscess, and a pseudoaneurysm at the petrous segment of the left internal carotid artery developed. The pseudoaneurysm caused bleeding from the left ear, and was treated with a 5 × 50-mm Surpass flow diverter. No recurrent bleeding was observed. Four months later, a follow-up angiography showed complete occlusion of the pseudoaneurysm on the left side, but a residual aneurysm could be detected on the right side. One year after the first intervention, the follow-up CT and magnetic resonance angiography revealed the complete occlusion of the aneurysms bilaterally. Conclusion The use of a flow diverter appears to be an efficient and safe method to occlude carotid pseudoaneurysms even in an inflammatory milieu.

[Low rate of oropharyngeal human papillomavirus infection among women with cervical lesion. Preliminary results from the South-Eastern Hungarian population]. / Oropharyngealis humán papillomavírus ritka elofordulása cervicalis laesióval rendelkezo nokben. Elozetes eredmények dél-magyarországi vizsgálat alapján.

INTRODUCTION: Although the natural history of cervical and oral human papillomavirus infection has been intensively investigated in the past years, the ability of this virus to infect oral and genital mucosae in the same individual and its potential to co-infect both cervical and oral mucosa are still unclear. AIM: The aim of the authors was to assess the presence of oropharyngeal human papillomavirus infection in women with cervical lesions in the South-Eastern Hungarian population. METHOD: The total of 103 women have been included in the study between March 1, 2013 and January 1, 2015. Brushing was used to collect cells from the oropharyngeal mucosa. Human papillomavirus DNA was detected using polymerase chain reaction, and Amplicor line blot test was used for genotyping. RESULTS: Oropharyngeal human papillomavirus infection was detected in 2 cases (3%). The detected genotypes were 31, 40/61 and 73 in the oropharyngeal region. CONCLUSIONS: The results indicate that in women with cervical lesions oropharyngeal human papillomavirus infection rarely occurs.

A comparison between transoral glottis-widening techniques for bilateral vocal fold immobility.

OBJECTIVE: Comparison of different endoscopic glottis-widening procedures designed for bilateral vocal cord immobility (BVCI) is a challenge. This is because a statistically efficient analysis and comparable clinical series is hard to obtain considering the variable aspects of the results and the evaluation methods. This study of a large number of cadaver larynges provides comparable, objective data for the evaluation of the possible postoperative breathing and voicing function. STUDY DESIGN: A morphometric study was performed on 50 male and 50 female larynges to compare the different suture lateralization and resection procedures. METHODS: The postoperative characteristic of glottic configuration was evaluated following vocal cord laterofixation, endolaryngeal arytenoid abduction lateropexy (EAAL), Schobel's external lateralization procedure (SELP), transverse cordotomy (TC), and medial and total arytenoidectomies (AE). The glottic area and the parameters determining the phoniatric outcomes were assessed by a digital image analyzer program. RESULTS: Improvement of glottic area was observed after all procedures, but arytenoid abduction procedures were significantly the most effective. However, the smallest vocal cord angles were found in TC and AE; the injury of the voicing structures results in a deterioration of vocal mechanics and can be reasonably assumed to negatively influence the voice. Endolaryngeal arytenoid abduction lateropexy and SELP may provide the best phonation closure when residual adduction regeneration can occur. CONCLUSION: This study demonstrates the complexity of the correct surgical decision making in BVCI. Procedures that utilize physiological abduction of the arytenoid cartilage seem to be more advantageous, especially if recovery of adductor function occurs. LEVEL OF EVIDENCE: N/A.

Comparison of endoscopic techniques designed for posterior glottic stenosis--a cadaver morphometric study.

OBJECTIVES/HYPOTHESIS: Posterior glottic stenosis may cause more or less severe dyspnea. The popular endoscopic procedures have only a limited role in the treatment. Considering our clinical experiences, endoscopic arytenoid abduction lateropexy (EAAL) after proper mobilization of the fixed joints provides an effective option even in high-grade stenoses. STUDY DESIGN: To confirm these clinical observations, a morphometric study was performed in 100 cadaver larynges (50 male, 50 female) to objectively compare the endoscopic glottis-widening procedures. METHODS: The postoperative measurements of the posterior commissure following EAAL, classic vocal cord laterofixation (VCL), transverse cordotomy (TC), and arytenoidectomy (AE) were assessed by a digital image analyzer program. The distance between the vocal process of the lateralized vocal fold and the midline, the angle between the axis of the posterior commissure midpoint, and the vocal process and laryngeal median sagittal line were measured. RESULTS: EAAL was found to be more effective in improving the posterior glottis configuration; however, AE and VCL were beneficial as well. CONCLUSIONS: Our morphometric study proved that organ-preserving EAAL provided more space in the posterior glottic area. Fibrous reconnection and contraction of the scar can be minimized in this way, which may be the clinical efficacy explanation.

Multiple costal cartilage graft reconstruction for the treatment of a full-length laryngotracheal stenosis after an inhalation burn.

After suffering an inhalation burn, a 22-year-old male was intubated for seven days. Full-length massive scar formation in the upper airway necessitated tracheostomy five months later. After this, the stenosis became complete in the cricoid region, and a long cannula was needed to maintain the severely damaged middle-distal trachea. After unsuccessful laser dilatation, the more stenotic 3 cm distal tracheal segment was resected, but two months later the stenosis recurred. As resection was ineffective, tracheoplasty was performed via a right-sided thoracotomy; the re-stenotized trachea was incised in length and successfully extended with 5 cm long, oval-shaped rib cartilage. Three months later, the complete cricotracheal stenosis was fixed by combined laryngofissure and cricoid laminotomy with two 6 cm×2.5 cm cartilage pieces sutured into the incisions. The middle portion of the trachea was expanded with a similar graft inserted into the anterior wall below the tracheostomy. The fixing T-tube was removed three months later, and the patient had an adequate airway two years after the last procedure. We conclude that multiple cartilage graft reconstruction can be successful even after the development of an extremely long airway stenosis following inhalation burn injury.

A new thread guide instrument for endoscopic arytenoid lateropexy.

OBJECTIVES/HYPOTHESIS: The varied etiology of bilateral vocal cord immobility (BVCI) requires a wide range of surgical approaches. A new endolaryngeal thread guide instrument (ETGI) is presented here for a minimally invasive endoscopic lateropexy of the arytenoid cartilage, which might serve as a basis for a simple solution for the main types of BVCI. STUDY DESIGN: Prospective study of BVCI patients who underwent surgery, including 22 bilateral vocal cord paralyses (BVCP), 12 mechanical fixations (MF), 10 posterior glottic stenoses, and two rheumatoid ankyloses. METHODS: The ETGI is based on a built-in movable curved blade with a hole at its tip to guide a thread in and out again between the skin and the laryngeal cavity. The loops formed around the arytenoid cartilage cause abduction. In cases of fixations, the cricoarytenoid joints were properly mobilized as a first step with a combination of cold technique and CO(2) laser. RESULTS: As spirometric tests proved, 32 patients achieved improved breathing ability. One temporary tracheostomy was necessary and one patient with ongoing radiotherapy could not be decannulated. Subjectively, twelve patients' voices improved or approximated normal quality due to complete vocal cord recoveries on at least one side after lateropexy was ceased. Incomplete recovery with more or less impaired voice was observed in 16 cases. Three MF patients and two BVCP patients with poor overall health condition had severe dysphonia. CONCLUSIONS: Combined with simple and readily available methods, endoscopic arytenoid lateropexy is an effective solution for BVCIs with various etiologies. The ETGI facilitates this procedure with rapid and safe creation of fixating loops at the proper position.
