In contrast to standard white light esophagoscopy, which simply observes the macroscopic appearance of mucosal lesions without any enhancement, chromoendoscopy (Lugol's solution chromoendoscopy or methylene blue contact endoscopy
) and "electronic chromoendoscopy" (autofluorescence or narrow-band imaging) enable detection of lesions that are not otherwise visible.
Contact endoscopy for the evaluation of the pharyngeal and laryngeal mucosa.
Contact endoscopy to determine blood flow direction in vocal fold microvascular lesions.
We conducted a retrospective study of the use of contact endoscopy in analyzing the vocal fold mucosal epithelium in adults who had been operated on at our hospital under general anesthesia for various nonlaryngeal diseases.
One diagnostic modality that is useful in this regard is contact endoscopy. This noninvasive method provides an insight into the microscopic picture of laryngeal mucosa epithelium.
Contact endoscopy was first described by Hamou et al in 1984 in a gynecologic diagnosis.
In this article, we describe our study of contact endoscopy in examining the epithelium of the vocal fold mucosa in smokers and nonsmokers who were free of clinical symptoms of laryngeal disease.
Findings on contact endoscopy were classified into four categories: normal mucosa, chronic laryngitis, dysplasia, and squamous cell carcinoma:
