“…1 It is worth noting, that some authors stress the difficulty of anesthetizing the facial nerve through the oral cavity, making this mechanism unlikely. 5,6 Additionally, this inferior alveolar nerve block was successful, indicating that it was done properly.…”

Facial nerve palsy, as a complication of an inferior alveolar nerve block anesthesia, is a rarely reported incident. Based on the time elapsed, from the moment of the injection to the onset of the symptoms, the paralysis could be either immediate or delayed. The purpose of this article is to report a case of delayed facial palsy as a result of inferior alveolar nerve block, which occurred 24 hours after the anesthetic administration and subsided in about 8 weeks. The pathogenesis, treatment, and results of an 8-week follow-up for a 20-year-old patient referred to a private maxillofacial clinic are presented and discussed. The patient's previous medical history was unremarkable. On clinical examination the patient exhibited generalized weakness of the left side of her face with a flat and expressionless appearance, and she was unable to close her left eye. One day before the onset of the symptoms, the patient had visited her dentist for a routine restorative procedure on the lower left first molar and an inferior alveolar block anesthesia was administered. The patient's medical history, clinical appearance, and complete examinations led to the diagnosis of delayed facial nerve palsy. Although neurologic occurrences are rare, dentists should keep in mind that certain dental procedures, such as inferior alveolar block anesthesia, could initiate facial nerve palsy. Attention should be paid during the administration of the anesthetic solution.

“…By causing reflex vasospasm, this leads to ischaemia of the facial nerve. Another theory is that dental anaesthesia or surgery could act as a precipitating factor, reactivating latent herpes simplex virus 1. Mastoidectomy also causes iatrogenic facial palsy most commonly at the second genu of the facial nerve.…”

SUMMARYA 40-year-old woman underwent marsupialisation of a symptomatic retrocerebellar cyst. She developed pseudomeningocoele after the procedure. CT of the brain showed hydrocephalus. Therefore, a right-sided ventriculoperitoneal shunt procedure was performed. Unfortunately, the patient developed lower motor neuron-type facial paralysis immediately after the surgery. We localised the site of injury in the distal fallopian canal probably during tunnelling of the subcutaneous tract for passage of the shunt. We discuss the steps to be followed to avoid such mishaps with a brief review of the literature. BACKGROUND

“…HSV et VZV ont été incriminés, l'origine herpétique pure se différenciant par l'absence de douleur et d'érythème dans la zone de Ramsay-Hunt qui caractérisent l'origine zostérienne. Les cas de paralysie faciale périphérique après une anesthésie pour des soins dentaires sont très peu nombreux : 20 à 30 cas pour 100 000 [5,6]. Il n'y a aucune hypothèse satisfaisante pour expliquer cette complication rare.…”

Résumé -Introduction : L'atteinte du nerf facial est angoissante pour le patient du fait de la déformation faciale qu'elle entraîne et pour le praticien qui se sent impuissant. La survenue d'une paralysie faciale périphérique, suite à des soins dentaires, est rare. Lorsqu'elle survient, aucune notion de traumatisme ou d'étiologie iatrogène ne peut être mise en cause de manière formelle. Observation : Le cas d'une patiente atteinte d'une paralysie faciale périphérique de grade IV selon la classification de House-Brackmann apparue suite à une anesthésie loco-régionale au foramen mandibulaire est décrit. Discussion : La notion de réactivation du virus varicelle-zona suite à un stress quel qu'il soit serait l'origine la plus probable. L'American Association of Neurology recommande la mise en place d'un traitement combiné de prednisolone (1 mg/kg/j) et d'aciclovir (400 mg 5 ×/j) pendant 10 jours ; il est également admis que toute paralysie faciale doit être prise en charge le plus précocement possible, idéalement dans les 72 heures, le succès du traitement dépendant en grande partie de sa rapidité d'instauration. Abstract -Introduction:Any facial nerve injury is a distressing condition for both the patient because of the facial deformity it leads and the practitioner who feels powerless. The occurrence of facial palsy following dental care is rare. When it occurs, any notion of trauma or iatrogenic etiology cannot be questioned formally. Observation: This article focuses on the case of a patient with a grade IV peripheral facial palsy according to House-Brackmann's classification, appeared after regional anesthesia at the mandibular foramen. Discussion: The concept of reactivation of varicella-zoster virus following stress would be the most likely origin. The American Association of Neurology recommends the establishment of a combined treatment of prednisolone (1 mg/kg/day) and aciclovir (400 mg 5 times/day) during 10 days, it is also recognized that any facial paralysis should be supported as early as possible, ideally within 72 hours, the success largely depends on the rapidity of introduction of treatment.
