Comparison of Hybrid Laryngotracheal Reconstruction to Traditional Single and Double-Stage Laryngotracheal Reconstruction

Abstract

Objectives:

(1) Describe outcomes from and modifications to the hybrid, also known as the one-and-a-half stage, laryngotracheal reconstruction (LTR) technique. (2) Compare this technique to traditional single and double-stage LTR (ssLTR/dsLTR).

Methods:

Retrospective review of patients under 18 years of age who underwent LTR by a single surgeon at a tertiary care otolaryngology specialty hospital from July 1, 2009, to December 31, 2013, was performed. Charts were assessed for age, sex, etiology of stenosis, type of reconstruction, comorbidities, length of stay, complications, and tracheostomy status.

Results:

Forty-four patients were identified, with 13 one-and-a-half stage LTRs, 27 ssLTRs, and 4 dsLTRs. Of the one-and-a-half stage LTRs, an operation-specific decannulation rate of 77% was noted, comparable with those for ssLTR and dsLTR. The one-and-a-half stage LTR technique offered a significantly shorter period of narcotic use when compared with ssLTR (16 vs 23 days, P < .01). Average length of stay for ssLTRs and hybrid LTRs was identical at 16 days; difference in length of stay between hybrid and dsLTRs was not statistically significant (16 vs 12.5 days, P = .16).

Conclusions:

The hybrid LTR technique is well-tolerated and useful in patients of all ages. Narcotics are able to be weaned more quickly because of the presence of a secure airway at all times via the existing tracheostomy. Use of a long stent prevents formation of granulation tissue that may be seen with a suprastomal stent. This technique should be considered in patients with high-grade stenosis with a pre-existing tracheostomy.
