Abstract
To present a nonwalled all-detachable retractor that simultaneously exposes the mouth, pharynx, and larynx. The proposed instrument is composed of a mouth-gag with a set of 5 interchangeable angled tongue blades, and a pharyngeal lever that provides internal laryngopharyngeal distension. Sixty-five patients were submitted to tonsillectomy, adenoidectomy, and endolaryngeal surgery with the workspace provided by the manufactured scope. Proper exposure of the upper aerodigestive tract was achieved in all patients. Naked eye, varied endoscopes, and special curved instruments were used to examine, lase, and manipulate tissues. Bimanual surgery was possible due to self-retaining adjustment and a clamp for endoscopes. This instrument allowed for an ample exposure from mouth to glottis in adults and children. Opposed to linear laryngoscopes in which the patient adapts to the instrument, its unique design adjusts to patients' anatomy and to many clinical situations.
