Traumatic facial nerve palsy in newborns: is it always iatrogenic?

We sought to report an updated incidence, risk factors, and outcome of traumatic facial palsy (TFP) in newborn infants born at King Abdulaziz Medical City (KAMC), Riyadh, Saudi Arabia. We performed a 12-year retrospective study at KAMC. The records of infants with the diagnosis of TFP during the study period were reviewed and compared with 148 healthy term infants born during the same study period. Among 83,067 infants delivered between January 1994 and December 2005, 29 infants were diagnosed with TFP for an incidence of 0.03%. Forceps delivery and maternal primiparity were the only significant risk factors for TFP. Only 7 (24.1%) of these infants were delivered by cesarean section. The other 22 cases of TFP (75.9%) were delivered without any forceps application. Almost all infants (93%) with TFP had spontaneous recovery within 2 months. Only one child suffered from permanent facial weakness when he was last examined at the age of 12 years. Although forceps delivery was considered the most significant risk factor, currently most of the cases occur spontaneously without forceps application. The majority of infants with TFP will recover spontaneously within the first 2 months of life. © Thieme Medical Publishers.
