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.
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.
For this retrospective study, we studied the use of contact endoscopy to analyze the mucosal epithelium of the vocal folds of 71 smokers who were operated on at our hospital under general anesthesia for the treatment of various nonlaryngeal diseases.
Findings on contact endoscopy were classified into four categories: normal mucosa, chronic laryngitis, dysplasia, and squamous cell carcinoma:
Contact endoscopy detected abnormal findings in 7 of the 71 smokers (9.
In our study, contact endoscopy demonstrated early pathologic findings in 7 of the 71 smokers (9.
Contact endoscopy is the only diagnostic method that enables precise in vivo microlocalization of early vocal fold lesions.
The growth of a tumor is accompanied by development of its own microvascularization, which is irregular and easily discernible on contact endoscopy.
Our study demonstrates that the use of contact endoscopy as a standard diagnostic method in long-time cigarette smokers during procedures performed with general anesthesia is fully justified.
