Glottic sulcus is a degenerative lesion consisting of the empty “pocket” of what was formerly a cyst under the mucosa of the vocal cord. The lips of a glottic sulcus may be seen faintly during laryngeal stroboscopy. Or, vibratory characteristics may suggest this lesion.
A glottic sulcus may be overlooked unless one is familiar with this entity. To paraphrase eminent French laryngeal microsurgeon Dr. Marc Bouchayer, these lesions are diagnosed much more frequently once you know about them than before. At present, aside from having the patient coexist peacefully with this problem via voice therapy and other measures, surgery is the primary treatment modality.

Nuances of Endotracheal Tube Injury
This woman with high-risk comorbidities of diabetes and obesity, was in ventilated in ICU more than a month for pulmonary complications of Covid-19 infection. She had an orotracheal tube in place for 3.5 weeks, and then a tracheotomy tube was placed. Now at her first visit a year later, she remains tracheotomy-dependent, and is told she has bilateral vocal cord paralysis (disproven in the following photo series).
The plan here is posterior commissuroplasty, followed by placement of a smaller trach tube and a trial of plugging. If plugging is tolerated during the day, she will need a sleep study with it plugged at night, given the tracheomalacia and her obesity.
Glottic Sulcus: Laryngeal Videostroboscopy
Glottic sulcus is a degenerative lesion consisting of the empty “pocket” of what was formerly a cyst under the mucosa of the vocal fold. The lips of the sulcus may be seen faintly during laryngeal stroboscopy. Or, vibratory characteristics may suggest this lesion.
Nodules and Other Vocal Cord Injuries: How They Occur and Can Be Treated
This video explains how nodules and other vocal cord injuries occur: by excessive vibration of the vocal cords, which happens with vocal overuse. Having laid that foundational understanding, the video goes on to explore the roles of treatment options like voice therapy and vocal cord microsurgery.
