Channeled fiberoptic for vocal cord polyp excision under spontaneous respiration using intravenous anesthesia and hi-flow nasal oxygen (STRIVE-Hi) technique: A case report and review of the literature

Microlaryngoscopy for benign vocal cord lesion excision is a procedure with good outcomes and relatively few complications that is performed worldwide. The anterior one-third of the vocal cords is a relatively common site to find benign polyps, and the excision of cases with adequate laryngeal exposure is relatively easy. However, they can sometimes present a challenge when laryngeal exposure is suboptimal, which leads to trouble in accessing the site. The factors that can lead to difficulties in laryngeal exposure are numerous, such as restricted mouth opening, limited neck extension, large tongue size, and others. The preoperative prediction of difficult laryngeal exposure (DLE) can be obtained by different scoring and grading systems. We have used the Laryngoscore in this case. However, management options for such cases remain limited. Here, we present a case that was managed using channeled cup forceps under fiberoptic endoscopy with the STRIVE-Hi technique used to administer anesthesia.
