Background  Surgical resection of parapharyngeal space (PPS) tumors is very challenging. An endoscopic-assisted surgical approach to this region requires detailed and precise anatomic knowledge. The main purpose of this study is to describe and compare the detailed anatomy of the PPS via transnasal transpterygoid (TP) and endoscopic-assisted transoral (TO) approaches. Materials and Methods  Six fresh injected cadaver heads (12 sides) were prepared for dissection of the PPS via TP and TO approaches. Computed tomography (CT) with image-based navigation (Navigation System II; Stryker, Kalamazoo, Michigan, United States) was used to identify bony structures around the PPS...

INTRODUCTION: Chronic Eustachian tube dysfunction can cause several symptoms and middle ear conditions that can impact patient quality of life. It is estimated to be relatively frequent, affecting approximately 5% of adults. The diagnostic tools for this condition are still inadequate. In 2012, McCoul et al. published a questionnaire for the evaluation of Eustachian tube dysfunction named ETDQ-7. They established its replicability and validity. The cutoff point for the diagnosis of chronic Eustachian tube dysfunction was equal to or greater than 14...

BACKGROUND: Untreated chronic otitis media severely impairs quality of life in affected individuals. Local destruction of the middle ear and subsequent loss of hearing are common sequelae, and currently available treatments provide limited relief. Therefore, the objectives of this study were to evaluate the feasibility of the insertion of a coronary stent from the nasopharynx into the Eustachian tube in-vivo in sheep and to make an initial assessment of its positional stability, tolerance by the animal, and possible tissue reactions...

The patulous Eustachian tube syndrome was described more than 150 years ago, but up to the present time some of its aspects continue to be a challenge for both fundamental and clinical medicine. Certain issues of etiology and pathogenesis of this condition have until recently remained unclear which probably accounts for the failure of choosing the adequate methods for its medical correction. Despite the seemingly broad spectrum of the modern tools for the purpose including first and foremost the endoscopic and radiological techniques, verification of the patulous Eustachian tube may encounter difficulties for the specialists...

PURPOSE: Balloon dilation of the Eustachian tube is a treatment option for obstructive Eustachian tube dysfunction. The desired balloon position is in the cartilaginous portion. However, the balloon catheter may slide into the bony portion without the surgeon's knowledge. Knowing the length of the cartilaginous portion may improve catheter positioning, but there is no published research on measuring this portion selectively or on whether the length has an impact on development of disease or treatment outcome...

Introduction  Eustachian tube (ET) dysfunction plays an important role not only in the pathophysiology of various middle ear disorders, but also in predicting the outcome of the treatment. As there is no single test that assesses both the anatomic and physiological functions of the ET, a combination of tympanometry and dynamic slow motion video endoscopy may improve the sensitivity of ET function assessment. Objective  To find out if there is any correlation between dynamic slow motion nasal video endoscopy and impedance audiometry in assessing ET function in patients with middle ear diseases...

The term fibro-osseous lesion encompasses a spectrum of disorders ranging from inflammatory to neoplastic that microscopically exhibit a connective tissue matrix containing formless trabeculae of compact bone. Characteristically, they are located over healthy bone, from which they are abruptly differentiated. The majority of the lesions arise from the maxillofacial region; the occurrence of a lesion in the external auditory canal (EAC) being extremely rare as is in our case. The lesions present with a range of symptoms ranging from conductive hearing loss, Eustachian tube obstruction to bone erosion that develop due to the mass effect...

OBJECTIVE: Eustachian tube dysfunction (ETD) affects approximately 1% of adults in the general population. Non treated Eustachian tube dysfunction can result in chronic middle ear diseases, which have been shown to significantly affect taste sensitivity. A promising treatment is balloon dilatation of the Eustachian tube. The primary aim of the present study was to investigate whether individuals with ETD had impairment in chemosensory functions, and the changes of the chemosensory function after balloon dilatation of the Eustachian tube...

Otitis media (OM) is a group of inflammatory diseases of the middle ear (ME), regardless of cause or pathological mechanism. Among the molecular biological studies assessing the pathology of OM are investigations into the expression of C-type lectin receptors (CLR) in the ME and Eustachian tube (ET). To date, nine studies have evaluated CLR expression in the ME and ET. The expression of individual CLRs in mammalian ME and ET varies by species and model of OM. Assessments have shown that the patterns of CLR expression in the ME and ET vary; that CLR expression may vary by type of OM; and that the distribution and levels of expression of CLRs may depend on the presence or absence of inflammation, with variations even within the same species and same tissue...

PURPOSE: The determination of Eustachian tube dysfunction (ETD) subtypes in daily routines is based on symptoms of the patient, otoscopy, nasopharyngoscopy, tympanometry, pure tone audiometry, and Valsalva's test, even though this clinical assessment is often not sufficient to clearly diagnose the subtype. In the study, we have evaluated the possibility of the determination of different subtypes of ETD by pressure chamber measurements. METHODS: In a single-person pressure chamber, we exposed 17 patients to pressure increases and decreases...

OBJECTIVE The anterior transpetrosal approach (ATPA) was established in 1984 and has been particularly effective for petroclival tumors. Although some complications associated with this approach, such as venous hemorrhage in the temporal lobe and nervous disturbances, have been resolved over the years, the incidence rate of CSF leaks has not greatly improved. In this study, some varieties of air cell tracts that are strongly related to CSF leaks are demonstrated. In addition, other pre- and postoperative risk factors for CSF leakage after ATPA are discussed...
