title: [Orbital exenteration: an unusual cause of failure of assisted ventilation from a face mask].
abstract: Orbitary exenteration for tumor may concern ethmoidal wall, and may create a large communication between the orbital cavity and the cavum. We present the case of a patient scheduled for ocular prosthetic surgery after an unilateral orbitary exenteration. After intravenous induction of the general anaesthesia, anaesthesiologist failed to achieve adequate facial mask ventilation because of a great gas leakage from cavum to orbital cavity. Inserting packing in the orbitary cavity allowed to decrease gas leakage and to get adequate facemask ventilation. We recommend orbitary radiographic and clinical evaluations for patient with orbitary exenteration before general anaesthesia to evaluate the communication between the orbital cavity and the cavum. Such an anatomic communication may result in inefficient facial mask ventilation.
