Background: Managment of airway in cases of obstructing laryngeal tumors (OLT) is considered a challenging surgical problem. Tracheostomy can secure a patent airway; however, it was reported as a negative prognostic factor. Endolaryngeal debulking (ED) of these tumors, without doing tracheotomy, aims at ensuring a patent airway till starting the appropriate definitive treatment (DT). Coblation can induce localized molecular disintegration of the tissues with a low, temperature. Therefore, it can be used safely in airway surgery with low risks of postoperative edema or scarring. Aim af work: To study the safety of using temperature-controlled radiofrequency ablation (coblation) in ED of OLT without doing tracheostomy. method: This is an uncontrolled interventional prospective ease series study that included 16 cases having OLT. All of them were prepared for: coblation -assisted ED and biopsy. They were followed up till initiation of the DT. Results: From February 2023 till October 2O23,16 patients with OLT were first presented to our unit. 13 patients were intubated successfully and coblation-assisted ED without primary tracheostomy was done for them. Extubation was performed successfully, without the need for re-intubation or tracheotomy, in 12 cases with coblation debulking success rate of 92.3%. Conclusion : using coblation in endolarynrgeal debulking of obstructing laryngeal tumors is an effective surgical procedure to avoid temporary tracheostomy before initiation of the definitive treatment
