ABSTRACT
The mylohyoid nerve is the branch of the inferior alveolar nerve (IAN) which arises above the mandibular foramen. An abnormal communication between the mylohyoid nerve and lingual nerve (LN) was noted during the routine dissection of a male cadaver. Communicating branches between IAN and LN have been identified as a possible explanation for the inefficiency of mandibular anesthesia. The communication between mylohyoid and lingual nerve was found in this case after the LN passes in close relation to third molar tooth, which makes it more susceptible to injury during third molar extractions.

La Megadolicoectasia basilar (MDEB), es una enfermedad vascular raramente vista: consiste en una elongación excesiva y tortuosa de la arteria basilar. Puede estar asociada a diversas manifestaciones neurológicas como: cefalea, vértigo, pérdida de audición ideopática, y compromiso de nervios craneales por compresión. Conociendo la incierta incidencia de esta patología, reportamos el caso de un paciente masculino con 41 años raza blanca, en cuyos estudios de imagen (RMN, ARTERIOGRAFIA CONVENCIONAL, ANGIOTAC) se evidenció esta patología.
