Abstract Background and objectives Nerve injury following mask ventilation is a rare but serious anesthetic complication. The majority of reported cases are associated with excessive pressure applied to the face mask, long duration of mask ventilation, excessive digital pressure behind the mandible to relieve airway obstruction and pressure exerted by the plastic oropharyngeal airway. Case report We present a case of bilateral mandibular nerve injury following mask ventilation with short duration, most likely due to a semi-silicone facemask with an over-inflated cushion. Conclusion An over-inflated sealing cushion of a facemask may trigger difficult mask ventilation leading to mandibular nerve injury following mask ventilation. Alternative airway management techniques such as laryngeal mask airway should be considered when airway maintenance can only be achieved with strong pressure applied to the facemask and/or mandible.
