ABSTRACT Pyriform sinus malformations represent rare third and fourth branchial anomalies. Fistulae at the latter site were initially described and make up less than 1 % of all brachial anomalies. They may be discovered incidentally, or may present as a neck mass with recurrent infection, dysphagia, or airway compromise, and can be an unusual cause of dysphonia in infant and ... إقراء المزيد

Study design: A case series study. Methods: This study included all patients with dysphagia who had been admitted ... إقراء المزيد

ABSTRACT Our research is an additional genetic study to uncover the molecular mechanisms involved in head and neck squamous cell carcinoma (HNSCC) pathogenesis by studying loss of heterozygosity (LOH) and microsatellite instability (MSI) in both premalignant and malignant patients and to highlight the genotype of HNSCC in Upper Egypt. Patients with HNSCC from various parts of the world may have ... إقراء المزيد

ABSTRACT OBJECTIVES: In poor countries, hearing aids are too expensive for sensorineural hearing loss (SNHL) children's parents to offer for their children. These children may have middle ear problem, this will aggravate the level of hearing loss which may lead to delay in their ability to speak. This study is to highlight the prevalence of middle ear pathology in SNHL ... إقراء المزيد

Abstract This study was designed to measure auditory function in patients with chronic obstructive pulmonary diseases (COPDs) who gener- ally suffer from chronic hypoxemia. Control and COPD subject groups received a battery of tests to assess overall hearing sensitivity and peripheral (end-organ and eighth-nerve) and brain-stem auditory function, as well as blood-gas analysis. Results showed a statistically significant difference for ... إقراء المزيد

Tympanometry has become routine in clinical diagnosis of middle ear diseases since early 1970s. However, low frequency tympanometry is relatively insensitive to many lesions that affect the ossicular chain. This study on 20 patients with bilateral conductive hearing loss compares the pre-operative multifrequency tympanometry test results with their operative data. There is an accuracy of 78% in diagnosis of otosclerosis ... إقراء المزيد
