| Popis: | Highlights • The facial nerve (FN) and the retromandibular vein (RMV) are anatomical structures in close proximity. Anatomic variations of their relationship complicate parotid surgery and increase the potentiality of nerve injury or bleeding. • The true prevalence of such kind of variations seems to be underestimated, since the literature is restricted. • Novel variations of the relationship of the FN with the RMV are probable. Therefore, surgeons’ knowledge and perpetual awareness are fundamental and essential in order to perform safe parotid surgery. Introduction Identification and preservation of the facial nerve (FN) is a major challenge when performing parotidectomy. Anatomic variations of the relation between the FN and the retromandibular vein (RMV) pose a high risk of nerve injury and bleeding during the operation. Presentation of case An unusual anatomic variation of the relation between the FN and the RMV was unexpectedly detected during superficial parotidectomy. The operation was uneventful. A meticulous review of the recent literature was conducted as well. Discussion Variations of the relation between the FN and the RMV are mainly identified during the operation, since when performing parotidectomy, surgeons typically detect all the FN branches by locating the RMV. Such kind of variations, are not as rare as considered and their presence complicates parotid surgery and increases the potentiality of nerve injury and hemorrhage. Conclusion Surgeons’ deep knowledge and perpetual awareness concerning the probable anatomic variations of the relation between the FN and the RMV combined with detailed exposure of the operative field and of the relationship between these adjacent anatomical structures lead to safe parotid surgery. |
