Accuracy of high-resolution computed tomography in locating facial nerve injury sites in temporal bone trauma.

In this study, high-resolution, multislice computed tomography findings are compared with surgical findings in terms of the fracture location in patients with traumatic facial paralysis. Patients with traumatic facial paralysis with grade VI House-Brackmann scale who met the criteria for surgical decompression between 2008 and 2012 were included in this study. All the patients underwent a multislice high-resolution, multislice computed tomography (HRCT) using 1-mm-thick slices with a bone window algorithm.

Survivin gene polymorphism association with papillary thyroid carcinoma.

Survivin expression is correlated with suppression of apoptosis in human solid tumors. A polymorphism at position -31 (G/C) (rs 9904341) has been associated with cancer risk in several studies. We evaluated the correlation of this polymorphism with the risk of papillary thyroid carcinoma (PTC) in an Irananian population.

Correlation between E-cadherin and CD44 adhesion molecules expression and cervical lymph node metastasis in oral tongue SCC: Predictive significance or not.

The aim of this article was to evaluate the expression of E-cadherin and CD44 adhesion molecule in oral tongue squamous cell carcinoma (SCC) since inappropriate expression of adhesion molecules raises the metastatic ability of the tumor cells. Biopsy specimens from 92 patients with tongue SCC were examined for the expression of E-cadherin and CD44 by immunohistochemistry. The relationship of immunoreactivity with tumor stage and cervical lymph node metastasis was then analyzed.

Associations between HLA-C alleles and definite Meniere's disease.

Both genetic and environmental factors seem to play role in the etiology of Meniere's disease (MD). Several genes may be involved in susceptibility of MD including Human Leukocyte Antigens (HLA). The associations between MD and HLA alleles have been previously studied in other populations and certain HLA alleles were shown to be predisposing.

Intraoperative findings in revision chronic otitis media surgery.

In this study, we reviewed the surgical findings in a series of revision tympanomastoidectomy to determine the most common causes of failure in chronic otitis media surgery. The intraoperative findings at revision mastoidectomy with tympanoplasty of 116 patients were analyzed. The most common sites of pathologic tissue at revision surgery (with cholesteatoma and/ or granulation tissue) were unexenterated cells of the sinodural angle.
