A Clinical Case of Delayed Facial Nerve Suitation After Its Damage During Excision of a Dermoid Cyst of the Paratious Region in a Child

Facial paralysis is a severe pathology of various etiologies (infectious, traumatic, intraoperative), leading to functional disorders, depression of the emotional state. Peripheral lesions of the facial nerve are characterized by a mask-like facial expression with a wide-open palpebral fissure, lacrimation, and a lowered corner of the mouth on the side of the disease. Such a picture with loss of function of all or individual groups of facial muscles may be due to damage to the nerve in different parts of the complex path that it makes, starting from the cortical motor center to the terminal branches of the muscles of the face. It is very important to identify the presumptive level and depth of damage to the facial nerve in order to select a rational tactic for further surgical treatment. The article describes a clinical case of "end to end" suturing of the facial nerve in a 2-year-old child after its injury during excision of a dermoid cyst in the left parotid region. In this case, a method was used to reinnervate the mimic muscles of the face by means of end-to-end neurorrhaphy of the facial nerve with simultaneous repeated complete excision of the fistulous tract under the control of neuromonitoring. © 2023, Professionalnye Izdaniya.
