Aural symptoms in patients with temporomandibular joint disorders: multiple frequency tympanometry provides objective evidence of changes in middle ear impedance.

Objective: The association of temporomandibular joint (TMJ) disorders with aural symptoms, such as tinnitus, otic fullness, and subjective decrease of hearing acuity, is a well-established clinical observation. Although several hypotheses have been made about the otic-conductive origin of these complaints, conventional 226-Hz tympanometry has failed to demonstrate any middle ear abnormalities. The aim of this study was to evaluate patients with TMJ disorders with multiple frequency tympanometry (MFT).

Test-retest reliability of p13n23 and n34p44 components of vestibular evoked myogenic potentials in a large healthy population.

Objective: The aim of this study is to evaluate the reliability of the VEMP characteristics recorded in a large number of healthy subjects.

Methods: VEMP response was obtained on 75 healthy volunteers. Thirty-nine (39) of them were males and 36 were females.

Vestibular evoked myogenic potential eliciting in normal subjects: comparison of four different methods.

Objective: Vestibular evoked myogenic potential (VEMP) recording is a new method for testing the otolith receptors and vestibulospinal pathways. The aim of this study was to evaluate the characteristics of VEMP using four different techniques to find reasons to prefer one type of recording over the others.

Material And Methods: Twenty healthy persons, 10 males and 10 females with ages ranging from 20 to 57 years (mean age 41 years), were enrolled in this study.

Acoustic stapedial reflex in normal adults: biological behavior and determination of threshold levels.

Objective: To record acoustic reflex thresholds for admittance (Y) and its components, susceptance (B) and conductance (G) in healthy subjects and to establish normative data.

Study Design: Acoustic reflex threshold was determined in 100 healthy persons, divided into 5 age groups of 20 persons each (20-29, 30-39, 40-49, 50-59 and 60-69 years old). Detection was performed for Y, B, and G at 226-, 678- and 1,000-Hz probe tones, using 500-, 1,000-, 2,000- and 4,000-Hz stimuli.

Correlation of clinical and surgical findings to histological features (koilocytosis, papillary hyperplasia) suggesting papillomavirus involvement in the pathogenesis of cholesteatoma.

Background: The clinical course of cholesteatoma is rather unpredictable, as some cases show aggressive development, while others have a mild, more 'benign' nature. The aim was to correlate the clinical course and surgical findings of cholesteatomas with histological features.

Material/methods: The study included 45 patients with cholesteatoma, 29 of whom had surgically aggressive and 16 simple (not surgically aggressive) cholesteatoma.

Clinical effectiveness of tumor markers in squamous cell carcinoma of the larynx.

Background: The aim of this study was to examine and compare the value of the serum tumor markers CYFRA 21-1, TPA-M, SCCA and CEA in squamous cell carcinoma (SCC) of the larynx. Moreover, their possible clinical applications were studied.

Materials And Methods: The serum levels of CYFRA 21-1, TPA-M, SCCA and CEA were measured in 79 patients with histologically-proven squamous cell carcinoma (SCC) of the larynx before and after treatment and in 77 healthy volunteers.

Association between squamous cell carcinoma of the head and neck and serum folate and homocysteine.

Unlabelled: The aim of this study was to evaluate the serum levels of folate and homocysteine in patients with squamous cell carcinoma of the head and neck (SCCHN) and to correlate them with the clinical stage. An attempt was made to associate the results with the effects of smoking.

Materials And Methods: Serum levels of folate and homocysteine were measured in 150 patients with histologically-proven SCCHN before any treatment and in 150 healthy volunteers (77 smokers and 73 nonsmokers).
