Buffered vs Plain Lidocaine for Local Nasal Anesthesia

Transnasal Fiberoptic Laryngoscopy (TFL) is a common procedure in the otolaryngology clinic for the examination of vocal cord appearance and function, inspection and follow up of benign and malignant lesions, and investigating foreign body ingestion. There are many forms for applying preprocedural local nasal anesthesia such as atomizers, nebulizers, spray, soaked pads, or local anesthetic gel application. This study compares the effect of buffered versus plain lidocaine for local nasal anesthesia.
