RESUMO
BACKGROUND: Endoscopic type I tympanoplasty was originally introduced in the 1990s, and the extensive spread of this practice can be easily observed. The conventional technique performed involves the repair of a tympanic membrane perforation, and is defined as microscopic type I tympanoplasty. OBJECTIVE OF REVIEW: The aim of this study was the comparison of postoperative outcomes of both the endoscopic and the microscopic type I tympanoplasty. TYPE OF REVIEW: We conducted a meta-analysis in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. SEARCH STRATEGY: A systematic literature search was performed in the databases of PubMed, Embase, Cochrane Library, Clarivate Analytics-Web of Science, ClinicalTrials.gov, World Health Organization Library, and Scopus by inserting, 'myringoplasty OR (tympanoplasty AND perforation)' into the search query. We applied only a 'human' filter. We excluded non-English studies. Additional records were identified by checking the references of relevant studies. EVALUATION METHOD: Comparative studies were included in our analysis. We calculated the pooled odds ratio (OR) with 95% confidence interval (CI) for dichotomous outcomes and weighted mean difference (WMD) with a 95% CI for continuous outcomes. Additionally, we assessed the risk of bias and estimated the quality of evidence for each outcome. RESULTS: Our systematic search yielded 16 studies (involving 1179 interventions), eligible for analysis. The pooled graft uptake rate (OR: 1.21, CI: 0.82-1.77; I2 = 0.0%), the postoperative hearing results (WMD = -1.13; 95% CI: -2.72-0.45; I2 = 78.1%) and the operation time (WMD = -21.11; 95% CI: -42.60-0.38; I2 = 99.3%), were all comparable amongst the two techniques. In contrast, the endoscopic type I tympanoplasty outperforms when regarding the pooled canaloplasty rate (OR = 7.96; 95% CI: 4.30-14.76; I2 = 0.0%, P = 1.000) and features an increase in desirable cosmetic results (OR = 19.29; 95% CI: 11.37-32.73; I2 = 0.0%, P = 0.839), when compared with the microscopic approach. CONCLUSIONS: Based on our meta-analysis, the surgical outcomes of endoscopic type I tympanoplasty in terms of graft uptake rate, postoperative hearing results and operation time were comparable to the microscopic type I tympanoplasty. In regards to cosmetics, an increase in desirable results was achieved in the endoscopic group, particularly the incidence of canaloplasty which proved to be significantly lower.

BACKGROUND: We compared cost-effectiveness of anesthesia maintained with sevoflurane or propofol with and without additional monitoring, in the clinical setting of ear-nose-throat surgery. METHODS: One hundred twenty adult patients were randomized to four groups. In groups SEVO and SEVO+ anesthesia was maintained with sevoflurane, in group SEVO+ with additional bispectral index (BIS) and train-of-four (TOF) monitoring. In groups PROP and PROP+ anesthesia was maintained with propofol, in group PROP+ with additional BIS and TOF monitoring. RESULTS: Total cost of anesthesia per hour was greater in group SEVO+ compared to SEVO [ 19.95(8.53) vs. 12.15(5.32), p < 0.001], and in group PROP+ compared to PROP ( 22.11(8.08) vs. 13.23(4.23), p < 0.001]. Time to extubation was shorter in group SEVO+ compared to SEVO [11.1(4.7) vs. 14.5(3.9) min, p = 0.002], and in PROP+ compared to PROP [12.6(5.4) vs. 15.2(4.7) min, p < 0.001]. Postoperatively, arterial blood pressure returned to its initial values sooner in groups SEVO+ and PROP+. CONCLUSIONS: Our study demonstrated that the use of BIS and TOF monitoring decreased the total cost of anesthesia drugs and hastened postoperative recovery. However, in our circumstances, these were associated with higher disposables costs. Detailed cost analysis and further investigations are needed to identify patient populations who would benefit most from additional monitoring. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02920749 .

INTRODUCTION: The usefulness of nasal packing after endoscopic sinus surgery is still debated in the literature. AIM: Our aim was to evaluate the effects of a new chitosan-based nasal dressing in animal model. METHODS: Standard mucosal damage was caused in both nostrils during endoscope-assisted procedure in ten rabbits. Chitosan nasal packing was inserted in a randomly selected nasal fossa of each animal, while the other side was left unpacked. Symptoms were evaluated during nasal endoscopy on the 12th postoperative week. The degree of mucosal oedema, crusting, adhesions and the nasal discharge were observed according to the modification of the grading system of Berlucchi et al. The higher scores indicated the worse complaints. RESULTS: Assessing the adhesion formation, 1 point was given (mean: 0.1; standard deviation [SD]: 0.32) for the unpacked side, while in the tamponated side no adhesion formation was observed. The total score of crusting in the non-packed side was lower with 1 point (total score: 9, mean: 0.90; SD: 0.74) than in the chitosan side (total score: 10, mean 1.00; SD: 0.82). Discharge or mucosal oedema were not observed during the follow-up period. The mean rate, measured with electronmicroscopy, was 22.06% (SD: 0.25) in the chitosan side, while in the non-packed side it was 36.11% (SD: 0.48). The differences did not show any significance (p = 0.806). CONCLUSION: During the examinations, none of the animals suffered complications. The symptoms of the packed and the non-packed nasal cavities did not differ significantly on the basis of our examinations. Orv Hetil. 2018; 159(47): 1981-1987.

The benefits of nasal packing after endoscopic sinus surgery (ESS) are still debated in the literature. Our aims were to evaluate the efficacy, and the clinical effects of a totally degradable nasal dressing used after ESS. Thirty patients with chronic rhinosinusitis with nasal polyps were enrolled in a prospective, randomized, double-blind, controlled study. Every patient underwent ESS and a polyurethane nasal dressing was used in one nasal fossa and the contralateral fossa was left unpacked. The extent of mucosal edema, crust formation, bleeding tendency, presence of synechiae, amount of nasal discharge, and the patency of the ostiomeatal complex (OMC) was evaluated during nasal endoscopy on the first, fourth, and twelfth postoperative weeks. All clinical findings were statistically analyzed. Endoscopy showed a significant improvement in the patency of the OMC on the side with resorbable material at 4 weeks after surgery. Follow-up at week 12 showed that in addition to the OMC patency scores, synechia formation and nasal discharge were also significantly improved in the packed fossa. Polyurethane packing is an effective alternative for nasal packing following functional endoscopic sinus surgery.

The combination of obstructive sleep apnea syndrome and vascular malformation within the head and neck region is a rare condition, and interestingly, only a few cases have recently been published. Propagation of the vascular mass to the larynx and pharynx can cause breathing and swallowing difficulties. Due to these sypmtoms, examination and initiation of appropriate therapy for such patients are indeed challenging. We reviewed the literature available and present our case of a 64 year old woman emphasizing the complaints of sleep apnea syndrome and vascular malformation of the face and neck region. Polygraphic examination detected severe obstructive sleep apnea syndrome. The MR examination of the neck revealed extensive vascular mass narrowing the pharyngo-laryngeal region, thereby causing temporal bone destruction on the right side with intracranial propagation. ENT examination demonstrated significant narrowing of the pharyngeal lumen and the laryngeal aditus caused by multiple hemangiomas. CPAP titration showed the minimalization of the apnea-hypopnea index on the effective pressure level. Regular CPAP usage resulted in diminishing a majority of the patient's complaints. Our examination clearly demonstrates, obstructive sleep apnea syndrome coupled with significantly obstructing vascular malformation in the head and neck region can be effectively treated safely with a CPAP device, if surgical therapy is not possible. We summarized our findings and the data available in the literature to set up recommendations for the appropriate examination and therapy (including mask fit, etc.) of vascular malformations and hemangiomas causing pharyngo-laryngeal obstruction.

The aim of this retrospective study was to compare the 3-month postoperative hearing results following laser stapedotomy with the use of NiTiBOND versus Nitinol prostheses (31 and 39 patients, respectively). The operations were performed between September 2012 and September 2014, and between March 2006 and December 2012 regarding NiTiBOND and Nitinol, respectively. Twenty of the consecutive 31 patients were female and 11 were male for NiTiBOND, while 11 were male and 28 were female for Nitinol. The mean age was 43.8 years (range 22-61) and 46.9 years (range 28-83) for NiTiBOND and Nitinol, respectively. No significant cochlear trauma was documented postoperatively. The mean air-bone gap (ABG) for the frequencies 0.5, 1, 2 and 3 kHz at the 3-month postoperative follow-up was 7.6 dB (SD 4.7), and 9.3 dB (SD 4.1) for NiTiBOND and Nitinol, respectively. The differences between the mean pre- (p = 0.179), and postoperative (p = 0.059) ABG of the two groups were not significant. ABG closure within 10 dB was achieved in 77.4 and 59 % for NiTiBOND and Nitinol, respectively, the difference was not significant (p = 0.10). Two cases of delayed facial paralysis occurred, 1 with Nitinol and 1 with the NiTiBOND. All patients attained an ABG <20 dB following surgery. Laser stapedotomy with the application of either heat-memory piston prosthesis allowed an easy and minimally invasive approach with excellent short-term hearing results when the NiTiBOND prosthesis was applied. Laser application allowed manipulation in a bloodless environment and avoided manual crimping of the incus.

Cervical regional lymphadenectomy, also known as neck dissection, is a fundamental procedure in head and neck surgery. Its evolution over 110 years resulted in a great deal of confusion in the literature and in clinical practice, due to the heterogenicity in training, classification and surgical techniques, which makes outcomes comparability virtually impossible. The authors aim to clarify this situation in a structured manner, in order to facilitate communication among all specialists involved in multidisciplinary head and neck cancer care. The ultimate goal is to make sure that each and every head and neck cancer patient receives their optimal treatment. Review of the history and literature with statistical comparison of the two mainstraim methods regarding their nodal yield results. The applied surgical technique has a significant impact on nodal yield. An appropriate surgical concept achieves maximum oncologic benefit, minimum surgical morbidity with optimized adjuvant indications. Orv. Hetil., 2016, 157(47), 1871-1879.

Aim of the study - General anesthetics, arterial hypotension and hypoxia developing during anesthesia may result in impaired memory and a decline in other abilities (such as attention, concentration, linguistic and writing abilities). Our aim was to detect changes in cognitive functions due to surgery and anesthesia with controlled arterial hypotension. Materials and methods - We studied combined and intravenous anesthesia detecting pre-and postoperative cognitive functions, intraoperative haemodynamic parameters, demographic data, other data of case history and surgical data. The Montreal Cognitive Assessment test was applied in the randomized, prospective study. The preoperative data served as basis for comparison. The second test was performed following surgery when patients were fully awake. Both groups included 30 patients. Results and conclusion - After both narcosis methods (postoperative second hour) cognitive functions were significantly deteriorated (p<0.05). Median MoCA before sevoflurane anesthesia was 24 points (interquartile range: 22-25), postoperative value was 20 (19-21) (p<0.05). Median MoCA before propofol anesthesia was 24 points (23-26), postoperative value was 20 (18-22) (p<0.01). Intraoperative arterial blood pressure, pulse rate and oxygen saturation values did not correlate with worsening of cognitive function (Pearson correlation coefficient values between -0.19 and 0.42). Execution is influenced by age (negative correlation) and education (positive correlation).

Besides cold-steel and laser instruments, the use of radiofrequency (RF) devices in transoral microsurgery is getting increasing popularity mainly due to its minimal thermal effect on the collateral soft tissue. Authors summarize their surgical technique, results, and experience gained with RF applied during laryngeal interventions at the Department of Otorhinolaryngology, Head and Neck Surgery at Medical School, University of Pécs. Transoral microsurgery using radiofrequency was carried out in 23 cases in total between 1 January 2011 and 1 March 2013. Fourteen histopathologically different benign lesions and 9 malignant planocellular carcinomas of the larynx were removed using different Micro-Larynx RF Probes powered by Surgitron Dual 4.0 MHz Frequency RF (Ellman International, Oceanside, NY, USA) device. No major bleeding event occurred during or after the procedures and neither laryngeal oedema nor significant postoperative pain was recorded. Authors also reviewed the international literature in this topic while detailing some of their most interesting cases.

The aim of this study was an evaluation of the mid-term hearing results after the implantation of a self-crimping heat memory Nitinol piston in stapes surgery. The 12-month postoperative results were compared with those at a minimum of 3 years (maximum 6.7, average 4.4 years). The medical records of all 44 patients who underwent surgery with a Nitinol piston for stapes fixation between November 2005 and January 2007 were evaluated retrospectively. The prostheses used in all cases measured either 4.5 or 4.75 × 0.6 mm. We hypothesized that the 12-month postoperative hearing results would be permanent after an average follow-up of 4.4 years. Thirty-two of the 44 consecutive patients were females and 12 were males. Their mean age was 40.4 years (range 27-69). All underwent a 12-month postoperative audiometric evaluation. 38 (30 females, 8 males, average age 45, range 28-77 years) of the 44 were available for mid-term 4.4-year (minimum 3 years, maximum 6.7 years) postoperative audiometric evaluation. The mean air-bone gap (ABG) for the frequencies 0.5, 1, 2 and 3 kHz at the 12-month postoperative follow-up was 11 dB (SD 4.1) and that after an average 4.4-year postoperative evaluation was 6.4 dB (SD 3.6). The mean decrease in ABG after 12 months was 19.5 dB, and that after the average 4.4 years was 21.3 dB. ABG closure within 10 dB was achieved in 77.2 % after 12 months and in 89.5 % after the average 4.4 years. No patient with an ABG > 20 dB was recorded after the average 4.4 years. The mean air conduction threshold at 4 kHz was examined pre and postoperatively so as to indicate any possible inner ear damage. At the 12-month follow-up, the difference between the pre and postoperative values was -2.5 dB, whereas after the average 4.4 years the difference was surprisingly +13 dB. The individual AC improvements were also demonstrated with the use of Amsterdam Hearing Evaluation Plots (AHEPs). The Nitinol prosthesis allowed excellent intraoperative handling and no postoperative complication was reported. As compared with conventional stapes prostheses, the Nitinol-based SMart prosthesis is a safe and reliable stapes prosthesis. Our mid-term audiometric evaluations revealed that the audiometric parameters demonstrated a hearing improvement between the postoperative 12-month and average 4.4-year examinations. We consider the elimination of manual crimping and the use of a "non-touch" hand-held laser technique has a positive impact on the mid-term audiometric results. Most of the previous studies presented only relatively short-term (from 6 weeks up to 6-12 months) audiometric evaluations. Complications are rare, but a longer follow-up is needed to establish the long-term stability.

Összefoglaló. Fej-nyaki daganattal diagnosztizált és kezelt betegeknél a szájon keresztüli táplálás gyakran nem lehetséges vagy nehezítetté válik a kezelés valamelyik fázisában. A beteg enteralis táplálásának biztosítására tartós és hatékony megoldást kell nyújtanunk, erre megfelelo választás lehet a percutan endoszkópos gastrostomia. A fej-nyaki régióban a daganat elhelyezkedése, kiterjedtsége és a mutétek miatt megváltozott anatómiai viszonyok sokszor gátat szabnak a gasztroszkóp hagyományos, szájon át történo sikeres levezetésének, és így különleges megoldásokra lehet szükség. Közleményünkben egy, a szakirodalomban is ritkán alkalmazott percutan endoszkópos gastrostomakészítésrol számolunk be. A bemutatott esetben egy kiterjedt, rosszindulatú fej-nyaki daganat miatt totális maxillectomián és orbitaexenteratión átesett betegben a mutét következtében kialakult arcdefektuson át történt a gastroscopia és a tápszonda levezetése, ugyanis komplett szájzár következtében a beteg a táplálkozásra képtelen volt. A fent említett módszerrel sikerült a beteg hosszú távú enteralis táplálását megoldani minimálinvazív módon. Az összetett kóros esetek gyakran állítják kihívások elé a gyakorló klinikust. Esetbemutatásunkkal szeretnénk felhívni a figyelmet a hagyományos, megszokott módszerek helyett sokszor nagyobb sikerrel alkalmazható, személyre szabott terápiás lehetoségekre. Orv Hetil. 2022; 163(3): 116-119. Summary. Peroral, enteral feeding is often impossible in patients with head and neck cancer. Percutaneous endoscopic gastrostomy is a well-established, quick, minimally invasive, and safe procedure for providing long-term enteral feeding. Space-occupying tumour mass and altered anatomy due to surgery inhibit the gastroscope's peroral introduction and the feeding tube's placement in some instances. Various access routes and modified insertion techniques are recommended to overcome the feeding tube insertion challenges. We present a rare case of a 64-year-old head and neck cancer patient who was unable to eat orally due to trismus and had a facial soft tissue defect following total maxillectomy and orbital exenteration. A complete oesophago-gastro-duodenoscopy and feeding tube insertion were performed transfacially. Percutaneous endoscopic gastrostomy was successful and uneventful via the maxillary and orbital soft tissue facial defect. No complication was noted, and long-term enteral feeding of the patient was provided in a minimally invasive way. Surgeons often face challenging cases when treating patients with head and neck cancer. The modification of standard procedures is sometimes required to adapt surgical techniques to the patient's specific case. Orv Hetil. 2022; 163(3): 116-119.

BACKGROUND: Nonarteritic Anterior Ischemic Optic Neuropathy (NAION) is the second most common cause of optic nerve-related permanent visual loss in adults. AIM: We aimed to analyze the efficacy of the noninvasive and minimally invasive therapeutic options of NAION. METHODS: We performed a systematic literature search in MEDLINE, EMBASE, and CENTRAL from inception to 10 June 2019 to identify the studies that report on the effect of different therapies on visual acuity (VA) and visual field (VF). Weighted mean difference (WMD) with 95% confidence interval (CI) was calculated for these outcomes. The efficacy of steroids was investigated in quantitative, oxygen, steroid plus erythropoietin (EPO), levodopa/carbidopa, memantine, and heparin-induced extracorporeal LDL/fibrinogen precipitation (HELP) therapies and other therapeutic modalities in qualitative synthesis. RESULTS: Thirty-two studies were found to be eligible. We found that steroid therapy compared to control did not improve VA (p = 0.182, WMD = 0.14, 95% CI: -0.07, 0.35) or VF (p = 0.853, WMD = 0.16, 95% CI: -1.54, 1.86). Qualitative analysis could be performed for oxygen, steroid plus EPO, and HELP as well, however, none of them showed VA and VF benefit. Two individual studies found memantine and levodopa beneficial regarding VA. CONCLUSION: Our systematic review did not reveal any effective treatment. Further investigations are needed to find therapy for NAION.

Despite modern diagnostic procedures and up-to-date therapy, the survival of head and neck tumour patients is unfavourable. This can be explained by several factors, one of which is the late recognition of the tumour. This study related to the changes in expression of the c-myc and Ha-ras oncogenes and the p53 tumour suppressor gene as biomarkers in head and neck cancer cases. The gene expressions were investigated on RNA gained from peripheral white blood cells of head and neck cancers patients before and after definitive treatment. The results were compared with those on a control group of patients with non-tumorous diseases. The gene expressions were significantly higher in the cancer group than that in the control group (volunteer medical staff and medical students). After definitive treatment, the expressions of all these genes were decreased in patients in whom there was no recurrence of the tumour, but enhanced in the event of recurrence. Such measurement may serve as reliable biomarkers to monitor tumour development and the efficiency of therapy. The method may also be useful for the early identification of populations exposed to noxe, which may lead to the development of head and neck cancers.

Squamous cell carcinoma (SCC) of the head and neck region is the sixth most frequent malignancy with high mortality rate. Due to its poor prognosis it is considered a growing public health problem worldwide inspite of existing treatment modalities. Thus, early diagnosis of new diseases and recurrences is emerging on one hand, but on the other hand troublesome in the lack of reliable tumor markers in this field. The rapid development of proteomics has opened new perspectives in tumor marker discovery. Liquid chromatography/mass spectrometry (LC/MS) as the gold standard in proteomics enables the semi-quantitative analysis of proteins within various tissues. Abundance differences between tumor and normal tissue also can be interpreted as tumor specific changes. The aim of this study was to identify potential tumor markers of laryngeal/hypopharyngeal SCC by revealing abundance changes between cancerous and the surrounding phenotypically healthy tissue. After separating the phenotypically cancerous and healthy parts of formalin-fixed paraffin-embedded tissues, each sample underwent protein recovery process and tryptic digestion for label-free semi-quantitative LC/MS analysis. Eight proteins showed significantly higher abundance in tumor including tenascin, transmembrane emp24 domain-containing protein 2, cytoplasmic dynein light chain 1, coactosin-like protein, small proline-rich protein 2D, nucleolin, U5 small nuclear RNP 200-kDa helicase and fatty aldehyde dehydrogenase. Desmoglein-1 and keratin type I cytoskeletal 9 were down-regulated in tumor. Using Ingenuity Pathway Analysis we mapped the signaling pathways these proteins play role in regarding other tumors. Based on these findings these proteins may serve as promising biomarkers in the fight against laryngeal/hypopharyngeal SCCs.

OBJECTIVE: Compare intraoperative and postoperative outcomes of endoscopic and microscopic stapes surgery to provide objective evidence on whether the former is a better alternative than the latter. METHODS: We performed a systematic review and meta-analysis for studies that compared endoscopic stapes surgery with microscopic stapes surgery. Only studies that met predetermined criteria were selected and assessed for bias and quality. Primary outcomes were postoperative air-bone gap (ABG) and chorda tympani nerve injury. Secondary outcomes were average operating time, tympanic membrane (TM) perforation, and postoperative taste disturbance, pain, and dizziness. We calculated pooled odds ratios (ORs) with 95% confidence intervals (CIs) for dichotomous outcomes and weighted mean difference (WMD) with 95% CI for continuous outcomes. A confidence interval starting above 1.0 was considered as statistically significant. I2 and χ2 tests were used to quantify statistical heterogeneity. We used funnel plots to look for publication bias and performed a sensitivity analysis. RESULTS: Six nonrandomized cohort studies were eligible. The primary outcomes were ABG < 10 dB: OR = 1.80 (95% CI: 0.96 to 3.38), ABG = 11 dB to 20 dB: OR = 1.49 (95% CI: 0.76 to 2.93), ABG > 20 dB: OR = 2.51 (95% CI: 0.77 to 8.22), and chorda tympani injury: OR = 3.51 (95% CI: 1.55 to 7.93). Secondary outcomes were taste: OR = 2.36 (95% CI: 1.01 to 5.51), average operation time: WMD = 0.14 (95% CI: -11.69 to 11.98), TM perforation: OR = 1.70 (95% CI: 0.44 to 6.58); pain: OR = 0.84 (95% CI: 0.36 to 1.96), and dizziness: OR = 2.15 (95% CI: 0.94 to 4.89). CONCLUSIONS: Endoscopic stapes surgery is a valid alternative to the microscope. LEVEL OF EVIDENCE: 2a Laryngoscope, 130: 2019-2027, 2020.

BACKGROUND: Several studies have suggested that monitoring the depth of anaesthesia might prevent the development of postoperative cognitive decline. We aimed to conduct a meta-analysis to investigate the effects of bispectral index (BIS) monitoring in anaesthesia. METHODS: We searched in six major electronic databases. Trials were included if they discussed anaesthesia with and without BIS monitoring or low (<50) and high (≥50) BIS levels and which measured the risk of postoperative delirium (POD) and/or postoperative cognitive dysfunction (POCD). RESULTS: We included fourteen studies in the systematic review, eight of which were eligible for meta-analysis. BIS proved to be protective against POD at 1 day postoperatively in a cohort of 2138 patients (16.1% vs. 22.8% for BIS vs. no BIS groups, respectively; relative risk [RR] 0.71; 95% confidence interval [CI] 0.59 to 0.85, without significant between-study heterogeneity I2 = 0.0%, P = 0.590). The use of BIS was neutral for POCD at 1 week but protective for POCD at 12 weeks (15.8% vs. 18.8% for BIS vs. no BIS groups, respectively; RR = 0.84, CI: 0.66 to 1.08), without significant between-study heterogeneity (I2 = 25.8%, P = 0.260). The neutral association at 1 week proved to be underpowered with trial sequential analysis. In the comparison of low BIS versus high BIS, the incidence of POD at 1 day was similar in the groups. CONCLUSION: Our findings suggest a protective effect of BIS compared to not using BIS regarding the incidence of POD at 1 day and POCD at 12 weeks. However, limitations of the evidence warrant further investigation to identify those groups of patients by age, comorbid conditions and other individual variables who would benefit the most from the use of BIS monitoring.

The authors present a case report of a patient who was treated conservatively for a non-specific headache for more than a decade, while an arachnoidal cyst in the middle cranial fossa, over the temporal bone tegmen was diagnosed, but ruled out as the cause of the headache. The patient was referred to our ENT department with left, purulent ear discharge. Besides a chronic purulent otitis media, a cholesterol granuloma occupying the antrum, eroding the tegmen of the pyramid bone and penetrating into the middle cranial fossa was diagnosed. Case presentation of a patient with cholesterol granuloma, surgical options, differential diagnostic problems, and a literature review are presented. Tympanoplasty with cortical mastoidectomy was carried out to treat the chronic purulent otitis media, and the cholesterol granuloma was removed during transmastoid craniotomy. The iatrogenic temporal meningo-encephalic tissue herniation was repaired and the bone defect of the tegmen was reconstructed with septal cartilage. The patient's headache diminished immediately after the surgery. The chronic ear discharge stopped, the cholesterol granuloma was excised completely and the cerebral herniation was repaired successfully. Neither CSF leak, nor further herniation or meningitis were noticed. Two years after the operation the patient is asymptomatic. A large cholesterol granuloma, eroding into the middle cranial fossa can cause serious complications, and needs a high level of attention besides individualized surgical treatment based on the surgeon's abilities and skills.

Introduction: Malignant tumours of the sinonasal region - including those with invasion of the skull base - necessitate surgical resection. The majority of the cases give an opportunity to perform the procedure via minimally invasive, endoscopic approach, without external, craniofacial surgery. Aim: To assess our clinical experience in treating anterior skull base malignancies, performing minimally invasive endoscopic transcribriform resection. Method: Between February 2015 and July 2017, four male and one female patient underwent minimally invasive, endoscopic skull base procedure. The mean age was 64.6 years (59-70, median: 66). Every surgery was performed via transnasal, endoscopic transcribriform approach. In two cases Kadish C esthesioneuroblastomas, while in one case a T3N0 sinonasal non-differentiated carcinoma, a T1N0 intestinal type adenocarcinoma and a T4N0 squamous cell carcinoma was the indication of surgery, respectively. Results: The mean follow-up time was 22.8 months, between 14 and 46 months. Intraoperative complications did not occur during the procedures. Regarding the postoperative period, liquorrhoea and pneumocephalus occurred in one case. Complications were solved with lumbar drainage. During follow-up, neither residual nor recurrent tumour was observed in our patients. Conclusion: Endoscopic transcribriform resection of the skull base malignancies is a safe and viable alternative to the traditional open approach. Orv Hetil. 2019; 160(40): 1584-1590.

Wegener's granulomatosis - or, in other words, granulomatosis with polyangiitis - is an anti-neutrophil cytoplasmic antibody associated granuloma forming vasculitis, mainly affecting the respiratory tract and the renal system. Otologic manifestations of Wegener's disease can be otitis media with effusion or chronic silent mastoiditis with conductive hearing loss, but sensorineural hearing loss can also evolve. The diagnosis is based on the clinical appearance as well as the immunoserological and histopathological results. It is of paramount importance to begin a combined immunosuppressive treatment immediately, besides eradicating the otologic manifestations. The intractable cases of chronic otitis media due to Wegener's granulomatosis are challenging any ear surgeons. Subtotal petrosectomy has proved to be an effective solution in such cases to create a dry ear and to provide a safe surgical field for hearing restoration. The authors reviewed the literature and report a case history to present the modern management of Wegener's granulomatosis with otologic manifestation. Orv Hetil. 2019; 160(4): 151-157.

Pituitary adenylate cyclase activating polypeptide (PACAP) is widely distributed in ocular tissues, including the lacrimal gland. PACAP has been shown to influence the activity of several exocrine glands, but its effects on the composition of the tear film are not known yet. Similarly, the presence of PACAP has already been shown in the inner ear, but it is not known whether PACAP influences the composition of the endolymph. The aim of the present study was to investigate whether systemic injection of PACAP has any modulatory effects on the protein composition of the tear film and endolymph using chip electrophoresis and mass spectrometry analysis. Tear and endolymph samples were collected from rats and chickens, respectively, at various time points after systemic injection of PACAP. Fluid samples were further processed for chip electrophoretic studies. No difference was found in the protein composition of the endolymph between control and PACAP-treated animals. In contrast, tear samples showed a marked difference after PACAP treatment. Proteins in the molecular range 50-70 kDa, which showed a different chip electropherogram profile in every PACAP-treated sample, were further analyzed using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. PACAP treatment induced a repression in certain keratins, while others were induced after PACAP injection. Furthermore, PACAP treatment decreased aldehyde dehydrogenase expression. The present study provides a base for further studies on the in vivo effects of PACAP on the composition of tear film. These investigations may have important clinical relevance because of the noninvasive sample collection, the correlation between tear proteins and ocular diseases, and the possible presence of biomarkers for both ophthalmological and systemic pathological conditions.
