Johannesburg, 2019 / INTRODUCTION:
Laryngotracheal stenosis is rare but has become a well-recognized pathological
otorhinolaryngological condition. It develops when scar tissue forms in the trachea and
larynx. Laryngotracheal stenosis can cause significant morbidity and the management of it
is often complex. Tracheal resection with end-to-end anastomosis is a well-recognized
surgical procedure performed for treatment of larygotracheal stenosis and has been
shown to have great success.
AIM:
To review the short-term outcomes of tracheal resection for
larygotracheal stenosis at the Chris Hani Baragwanath Academic
Hospital Otorhinolaryngology Department.
METHOD:
This was a retrospective study, reviewing 24 patients with larygotracheal stenosis who
underwent segmental tracheal resection with end-to-end anastomosis at the Chris Hani
Baragwanath Academic Hospital, performed between 2005 and 2015.
RESULTS:
The study included 24 patients with ages ranging from 18 to 64 years. There were 15
(62.5%) males and 9 (37.5%) females. The causes of larygotracheal stenosis were
prolonged intubation in 22 (91.7%) and inhalation burns in 2 (8.3%) patients. Eleven
patients (45.8%) had postoperative complications, of which 4 (36.4%) were minor
complications and 7 (63.6%) were major complications. The outcomes of surgery were
excellent in 13 (54.2%), satisfactory in 8 (33.3%) and unsatisfactory in 3 (12.5%).
CONCLUSIONS:
Prolonged intubation was found to be the most common cause of larygotracheal stenosis.
Tracheal resection for larygotracheal stenosis has been shown to have satisfactory to
excellent short-term outcomes in terms of successful decannulation, voice quality, and
low morbidity. In our study, the surgery was successful in 21 (87%) patients, which is
comparable to success rates shown in the literature. Preoperative tracheostomy and
higher degree of stenosis Meyer Cotton (III and IV) were associated with high postoperative complications. Irrespective of the cause, tracheal resection is a good surgical option, for the treatment of patients with severe stenosis and those who have failed treatment from other alternative surgeries. / E.K. 2019
