Transillumination Assisted Cricopharyngeal Myotomy.

Abstract: Cricopharyngeal muscle myotomy (CPM) is a common intervention for relief of dysphagia in patients with Oculo-pharyngeal muscular dystrophy (OPMD). Because of difficulties in approaching and dissecting cricopharyngeal muscle in these patients, we used transillumination for the myotomy (TA-CPM). Transillumination is a simple technique to improve the guidance and navigation of the surgeon in determining the location and depth of myotomy.

Comparative analysis of micro-RNAs in human papillomavirus-positive versus -negative oropharyngeal cancers.

Background: Oncogenic mechanisms of human papillomavirus (HPV)-positive oropharyngeal cancer are still poorly characterized. Analysis of their microRNA expression profile might provide valuable information.

Methods: The microRNA expression profiles were analyzed by micro-arrays in 26 oropharyngeal cancers.

The musculocutaneous infrahyoid flap: surgical key points.

For the first time in 1979, it was described by Wang that the infrahyoid musculocutaneous flap (IHMC flap) appears to be extremely suitable for medium-sized head and neck defect. Nevertheless, this flap remains unpopular because of its pretended lack of reliability. The aim of this study is to describe the surgical key points and to expose its main advantages.
