Summary

simple combination of functional investigation, in form of laryngostroboscopy, together with conventional histopathological examination, provides a highly sensitive method in differential diagnosis of undiagnosed vocal folds irregularites

Description

Vocal folds irregularites often manifest as mucosal surface changes of leukoplakia, erythroplakia, or erythroleukoplakia. These gross mucosal changes may represent benign, premalignant, or malignant entities as they correspond to large spectrum of lesions ranging from simple totally benign keratosis with or without atypia up to invasive carcinoma. It is commonly encountered in the laryngology clinic and presents diagnostic and therapeutic challenges. Also, clinicians are tasked with understanding the nature of the lesions as well as functional consequences associated with the disease or its treatment.

The incidence of dysplasia within leukoplakic lesions approximates 50%. The rate of conversion to squamous cell carcinoma is contingent on the extent and/or degree of dysplasia. The vocal fold leukoplakia management remains challenging, and there is no unified surgical indication or guideline. The patient who suffers from vocal fold leukoplakia sometime need surgery, while some others do not need positive intervene, either nonsurgical or surgical. The laryngoscopic image is the major evidence to make the laryngologist suggest the patient to have a surgical or conservative treatment. However, there is no standard classification of the morphology of vocal fold leukoplakia in the literature.

Laryngostroboscopy is the most important tool for functional investigation in laryngological and phoniatric diagnosis. Stroboscopic evaluation mjb allows early detection of infiltrative processes of the vocal folds. Previous studies that tested exfoliative cytology, or brush biopsy provided a helpful tool, but, recourse of biopsies under general anesthesia lead to scarring of the vocal folds with consecutive voice impairment. Having encountered this problem, we present a proposal that refers to laryngostroboscopic examination combined with histopathology to put a differential diagnosis for these undiagnosed lesions.

Medical and Biotech [MESH] Definitions

A pair of cone-shaped elastic mucous membrane projecting from the laryngeal wall and forming a narrow slit between them. Each contains a thickened free edge (vocal ligament) extending from the THYROID CARTILAGE to the ARYTENOID CARTILAGE, and a VOCAL MUSCLE that shortens or relaxes the vocal cord to control sound production.

A disorder characterized by an intermittent abnormal VOCAL CORDS movement toward the midline during inspiration or expiration resulting in upper AIRWAY OBSTRUCTION.

Congenital or acquired paralysis of one or both VOCAL CORDS. This condition is caused by defects in the CENTRAL NERVOUS SYSTEM, the VAGUS NERVE and branches of LARYNGEAL NERVES. Common symptoms are VOICE DISORDERS including HOARSENESS or APHONIA.

The process of producing vocal sounds by means of VOCAL CORDS vibrating in an expiratory blast of air.

Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event. The development of the second neoplasm may or may not be related to the treatment for the previous neoplasm since genetic risk or predisposing factors may actually be the cause.
