Abstract:
Transient facial palsy is a rare complication after adenotonsillectomy. In this study, we report two cases who developed unilateral peripheral facial palsy immediately after adenotonsillectomy. The facial palsy in both cases completely recovered in 6 and 3h respectively without any treatment. We assumed the possible mechanism was deep infiltration of the local anesthetics into parapharyngeal space and then the direct action on the facial nerve. Therefore, we suggest three policies to avoid this complication: (1) inject the local anesthetics exactly into peritonsillar space, (2) avoid repeated injections or overdose, (3) slowly and gently inject the local anesthetics.

Etiology
Three primary contributing factors have been identified.
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
