Bell´s Palsy, a lower motor neuron injury that causes facial asymmetry due to facial weakness ranging from mild to total paralysis. Most of cases without determining a definitive established cause. The only authenticated findings are inflammation and edema of the facial nerve. In Mexico, it is among the first causes of medical attention. In the Mexican Clinical Practice Guide for Bells Palsy, thermotherapy, massage, and active exercises are recommended for its management. Perineural dextrose injection therapy (PIT) is a new treatment for peripheral neuropathy, which consists of injecting 5% buffered dextrose close to nerve pathways to restore nerve function and movement. Objective: Determine the effectiveness of perineural injection with dextrose versus conventional physical therapy for the treatment of patients with Bell´s palsy. Material and methods: Clinical trial, experimental, prolective, longitudinal, comparative and heterodemic. Resources and infrastructure: It will be carried out within the facilities of the Unidad de Medicina Física y Rehabilitación región centro. In human resources, doctors both specialists and residents in Rehabilitation Medicine and physical therapists. In material resources, stationery, for electroneuromyography study, perineural injection therapy, hand hygiene and disinfection, and for conventional rehabilitation therapy.
This study aims to evaluate the efficacy of dextrose perineural injection therapy while motivating and serving as a foundation for future studies to compare or create alternatives and therapeutic methods tailored to the needs patients, with the goal of improving functionality and aesthetics.

Application of perineural injection with buffered dextrose solution, adding 2.5 ml of 7.5% sodium bicarbonate to a 250 ml bottle of glucose solution at 5% concentration, applying 1cc of the solution at different points on the path of the facial nerve.

Efficacy in functionality
A= Functionality facial B= Recovery in time
Time frame: ≥8 weeks
Recovery in time
It is the action and effect of recovering or recovering (returning to oneself or to a normal state, take back what you had before, compensate) in a set time.
Time frame: 1= ≥8 weeks 2= ≤ 8 weeks
Functionality facial
1. Manual examination of facial muscles. It is a clinical evaluation to determine the function and strength of a person's facial muscles. 2. Clinical evaluation. The House-Brackmann rating scale used to evaluate facial function and severity of facial paralysis peripheral, which consists of six levels to evaluate six facial expressions starting from normal (grade I) and as the last degree considers total paralysis (grade VI). 3. Assessment electrophysiological with study of electroneurography of facial nerve that consists of the neuro conductions that they involve electrical stimulation of the nerve by measuring its motor response.
Time frame: ≥8 Weeks or ≤ 8 weeks
