New laryngoscope for endoscopic arytenoidectomies

J Laryngol Otol. 2014 Nov;128(11):991-5. doi: 10.1017/S0022215114002576. Epub 2014 Oct 15.

Abstract

Objective: During an endoscopic arytenoidectomy, an intubation tube must be elevated anteriorly with the laryngoscope to ensure an adequate surgical field. This paper describes a new laryngoscope that has a canal along the outer wall of the body and a ridge which runs along the canal.

Method: Ten patients underwent endoscopic total arytenoidectomy using this new laryngoscope and 10 patients underwent the same operation using a regular laryngoscope.

Results: The duration of all operations ranged between 25 and 65 minutes, with a median duration of 42.5 minutes. The median duration with the new laryngoscope was 39 minutes, and that with the regular laryngoscope was 49 minutes; this difference was statistically significant (p < 0.05).

Conclusion: This new laryngoscope shortened the duration of the endoscopic arytenoidectomy and facilitated the procedure by enlarging the surgical field. This new laryngoscope may be a beneficial surgical instrument for posterior endoscopic laryngeal operations.
