To evaluate the feasibility of the Shikani Optical Stylet (SOS)-guided intubation through a new Intubating Laryngeal Airway (ILA) in anticipated difficult airways caused by scar contracture of the face and neck. ⋯ The SOS-guided intubating method via the ILA is a feasible technique in patients with scar contracture of the face and neck. However, in patients with severe limitation of head extension, the use of SOS cannot be recommended. The SOS can be used as an alternative apparatus when the fibreoptic bronchoscope is not available.
