The risk factors for silent aspiration: A retrospective case series and literature review.

AIM: Evidence shows that 20%-30% of patients who aspirate do so silently. Research to date has not demonstrated clear evidence to indicate which patients are at higher risk of silent aspiration. Our aim was to use univariate logistic regression analysis of retrospective case review to determine potential patterns of silent aspiration. MATERIALS AND METHODS: We conducted a retrospective analysis of 455 fiberoptic endoscopic evaluation of swallowing (FEES) reports. The patients were divided into four groups: G1 - neurological diseases (n = 93), G2 - head and neck surgery (n = 200), G3 - gastroenterological diseases (n = 94) and G4 - other patients (n = 68). Data included the occurrence or absence of saliva penetration or aspiration, of silent fluid/solid food penetration or aspiration, type of penetration or aspiration, occurrence of cranial nerve paresis, radiotherapy and tracheostomy. Univariate logistic regression was used to evaluate independent risk factors of silent aspiration in the study population. Three models with different independent variables were considered. RESULTS: There is a statistically significant difference in the frequency of occurrence of silent penetration and aspiration within the groups (p < 0.001), with intraglutative being most frequent. Fluid and food penetration and aspiration correlated with saliva penetration and aspiration in all groups (p < 0.001). Cranial nerve paresis (IX and X), radiotherapy and tracheostomy correlate with saliva penetration and aspiration (p = 0.020 for cranial nerve paresis; p = 0.004 for radiotherapy; p < 0.001 for tracheostomy). One hundred and fifteen patients (45.81%) in the subgroup of patients with intraglutative aspiration had cranial nerve paresis (IX, X or IX-X). CONCLUSIONS: Patients who should be prioritised or considered to be at a higher need of instrumental swallowing evaluation are those with IX and X cranial nerve paresis, tracheostomy and those who have had radiotherapy, with saliva swallowing problems, especially after paraganglioma, thyroid and parathyroid glands and middle and posterior fossa tumour surgery. WHAT THIS PAPER ADDS: What is already known on the subject Clinical signs of penetration or aspiration include coughing, throat clearing and voice changes, while silent penetration or aspiration patients aspirate without demonstrating any clinical symptoms. The most common consequences of silent aspiration include aspiration pneumonia, recurrent lower respiratory tract infections and respiratory failure. Additionally, malnutrition and dehydration can be indicators of silent aspiration. Patients may unknowingly reduce their oral intake and lose weight. Retrospective studies have shown that 20%-30% of patients aspirate silently (e.g. patients after stroke, acquired brain injury, head and neck cancer treatment, prolonged intubation). Clinical examination of swallowing can miss up to 50% of cases of silent aspiration. What this paper adds to existing knowledge Currently, silent aspiration is often discussed in neurological literature, but its applications to head and neck surgery are limited. In this study, we identify head and neck surgery patients who should be prioritised or considered to be in higher need of instrumental swallowing evaluation due to a higher risk of silent aspiration. What are the potential or actual clinical implications of this work? Post-treatment structural changes can result in lower cranial nerve paresis (IX, X, XII) and face injury, in which vagus and glossopharyngeal nerves are injured. After tracheostomy and radiotherapy, patients with problems swallowing saliva need careful clinical examination, particularly cranial nerve examination.

Translation and Validation of the Dysphagia Handicap Index in Polish-Speaking Patients.

Dysphagia Handicap Index (DHI) is a self-assessment questionnaire which consists of 25 statements to examine three aspects of dysphagia patients' quality of life (QoL): functional, physical, and emotional. The patient can get a maximum score of 100 points. The study goal was to validate and translate the Polish version of the DHI (PL-DHI). One hundred and seventy-eight (178) individuals with oropharyngeal dysphagia with different etiology and 35 (thirty-five) asymptomatic adults with no history of swallowing disorders filled out the PL-DHI. Internal consistency was determined using Cronbach alpha coefficient, which was high for the total PL-DHI score (0.962). The reproducibility was high (r-Spearman correlation coefficient was 0.97 for total PL-DHI score). The PL-DHI's total score and its subscales were significantly higher in the dysphagia patients study group (SG) than in the healthy controls group (CG) (SG median: 36; CG median: 4). A strong correlation was observed between the PL-DHI score and the self-reported dysphagia severity measure (Spearman's correlation coefficient was 0.859, p < 0.001). The Polish DHI is a reliable and valid questionnaire for assessing dysphagia patients' QoL.

Chronic cough related to the upper airway cough syndrome: one entity but not always the same.

PURPOSE: Upper airway cough syndrome (UACS), described as chronic cough (CC) associated with allergic (AR), non-allergic rhinitis (NAR) or chronic rhinosinusitis (CRS), is one of the major causes of CC. We aimed to characterize a cohort of UACS patients with special attention to differences between patients with AR and NAR. METHODS: A prospective analysis of clinical data of patients, diagnosed with UACS between 2015 and 2018. RESULTS: There were 143 patients diagnosed with UACS, median age 52 years, women predominance (68.5%), The group comprised of 59 (41%) AR and 84 (59%) NAR subjects, CRS diagnosed in 17 (12%). Median cough duration: 48 months (IQR 24-120), median cough severity (VAS)-60 mm (IQR 42-78), median Leicester Cough Questionnaire (LCQ) score-11.3 (IQR 8.7-13.7), never-smokers: 70%. The most common symptoms: PND (62%), rhinorrhea (59%), nasal congestion (54%), abnormalities of sinus CT: septum deviation (62%), turbinates hypertrophy (53%), mucosal thickening (53%). UACS as the only cause of CC, was presented in 20 patients (14%). We found no differences between patients with AR and NAR in terms of age, gender, duration and severity of cough, BMI, blood eosinophil count, total IgE and FeNO. AR was associated with higher comorbidity of asthma than NAR (54% vs 35%, p = 0.019). Abnormalities in sinus CT scan were more frequently found in patients with NAR than AR (p = 0.018). CONCLUSION: NAR is the most common upper airway disease associated with UACS. Clinical characteristics of UACS patients with AR and NAR are similar with only minor differences between these groups. It seems reasonable to plan further studies concerning relationship of NAR and cough sensitivity, also in terms of potential similar neurogenic mechanism.

[Extended middle fossa approach in treatment of vestibular schwannoma--technique of surgery and postoperative complications]. / Poszerzony dostep przez srodkowy dól czaszki w leczeniu nerwiaków nerwu sluchowego--technika operacyjna w aspekcie mozliwych powiklan.

INTRODUCTION: The main tumor of cerebellopontine angle are vestibular schwannoma (80-90%). According to National Institute of Health Consensus Development Conference the best treatment method is microsurgery. There are three principal surgical approaches: translabyrinthin, retrosigmoid and middle fossa. Only the latter two approaches provide the possibility of hearing preservation. AIM: Technique of surgery and postoperative morbidity after MFA. MATERIAL AND METHODS: 39 patients (40 tumor) suffered from tumor of cerebellopontine angle, operated by using middle fossa approach in years 1998-2007. We evaluate hearing preservation and function of facial nerve and others postoperative morbidity. RESULTS: 22.5% of patients has hearing impairment and 32.5% has facial weakness. By individual cases we observed: CSF leak, meningitis, corneal ulceration, ischialgia, wound bleeding and venue thrombosis. 1/3 of patients suffered from headache and disequilibrium and 1/6 suffered from tinnitus. CONCLUSION: According to NIH middle fossa approach is one of three possible approaches in microsurgery of cerebellopontine angle tumors. There is possible total tumor removal with hearing preservation. Monitoring of facial and cochlear nerve during operation is recommended.

[Possibility of hearing preservation treatment by patient suffered from neurofibromatosis type 2: case report]. / Mozliwosci zachowania sluchu u pacjenta z neurofibromatoza typu 2--opis przypadku.

The main tumor of cerebellopontine angle are vestibular schwannoma (80-90%). Most of them are unilateral lesion but 5% of them are bilateral pathological mass. There are genetic disease like neurofibromatosis type 1 and 2. According to National Institute of Heath Consensus Development Conference the best treatment method is microsurgery. The possibility of hearing preservation surgery give middle fossa approach and suboccipital approach, radiotherapy or auditory brainstem implants and cochlear implants. The aim of the study is case report of the patient suffered from bilateral vestibular schwannoma. Early diagnosis and therapy enable hearing preservation and good facial nerve function.

The prevalence and types of oral- and pharyngeal-stage dysphagia in patients with demyelinating diseases based on subjective assessment by the study subjects.

BACKGROUND: Studies show that dysphagia is a common problem in patients with demyelinating diseases. However, there are no published studies on dysphagia in this group of patients, which would include the individual phases or the safety and effectiveness of the swallowing process. OBJECTIVE: The main objective of this study was to assess the prevalence of swallowing disorders and to characterize them based on subjective assessment by the study subjects with multiple sclerosis and Devic's syndrome. METHOD: The study included 72 patients (47 F, 25 M). Patients at risk of dysphagia were identified using the DYMUS, EAT-10 and SDQ questionnaires. To assess the type of oral- and pharyngeal-stage dysphagia, questions in the questionnaires were classified into groups according to symptoms typical of each stage. RESULTS: The risk of dysphagia and the need for instrumental examination were identified in 37.5% of the study subjects. Pharyngeal-stage dysphagia (repeated swallowing, increased effort of swallowing, cough, a feeling of food sticking in the throat) was reported to occur at a significantly higher frequency. However, no differences were found between difficulty in swallowing liquids and difficulty in swallowing solid food. CONCLUSION: There is a need for further research, which should include a detailed dysphagia-oriented diagnosis, with a view to gaining a detailed insight into the pathophysiology of deglutition in this group of patients.

[Tuberculoma mimicking the tumor of ponto-cerebellum angle as complication after postvaccinated tuberculous otitis media]. / Poszczepienne gruzlicze zapalenie ucha srodkowego i jego powiklania - opis przypadku.

INTRODUCTION: Tuberculosis is a major problem of constant importance all over the world. Notably, in the developed countries it is due to immunosuppressive therapy and AIDS. Primary otological tuberculosis constitutes a very small share of cases of this disease. Moreover, the appearance of tuberculomas remains unique to even greater extent. CASE REPORT: Clinical history of a patient who has already been infected tuberculosis for 60 years in result of the BCG vaccination. Ponto-cerebellum angle tumour appeared in his brain as complication ensuing the disease. The first therapeutic method used was based on antituberculous drugs, subsequent surgical intervention (cerebello-pontine angle tumor removal via translabirynthin approche) was necessary however. We suspected another cause of this lesion - cholesteatoma or facial nerve neurinoma. Correct diagnosis give only histopatological examination. Because of facial nerve palsy, facial nerve reconstruction was necessary (connection of n. VII and n. XII) CONCLUSION: This case reminds us that correct diagnosis of tuberculosis remains a serious problem despite the long experience and the development of diagnostics and treatment methods. Nowadays we observe the unusual clinical manifestations of the disease (e.g. such as ear pain, tinnitus, rapid hearing loss) more frequently.

[Facial nerve neurinomas]. / Nerwiaki nerwu twarzowego.

INTRODUCTION: Evaluation of diagnostic, surgical technique, treatment results facial nerve neurinomas and its comparison with literature was the main purpose of this study. METHOD AND MATERIALS: Seven cases of patients (2005-2011) with facial nerve schwannomas were included to retrospective analysis in the Department of Otolaryngology, Medical University of Warsaw. All patients were assessed with history of the disease, physical examination, hearing tests, computed tomography and/or magnetic resonance imaging, electronystagmography. Cases were observed in the direction of potential complications and recurrences. RESULTS: Neurinoma of the facial nerve occurred in the vertical segment (n=2), facial nerve geniculum (n=1) and the internal auditory canal (n=4). The symptoms observed in patients were analyzed: facial nerve paresis (n=3), hearing loss (n=2), dizziness (n=1). Magnetic resonance imaging and computed tomography allowed to confirm the presence of the tumor and to assess its staging. Schwannoma of the facial nerve has been surgically removed using the middle fossa approach (n=5) and by antromastoidectomy (n=2). Anatomical continuity of the facial nerve was achieved in 3 cases. In the twelve months after surgery, facial nerve paresis was rated at level II-III° HB. There was no recurrence of the tumor in radiological observation. CONCLUSION: Facial nerve neurinoma is a rare tumor. Currently surgical techniques allow in most cases, the radical removing of the lesion and reconstruction of the VII nerve function. The rate of recurrence is low. A tumor of the facial nerve should be considered in the differential diagnosis of nerve VII paresis.
