Retromandibular Fossa

The retromandibular fossa or retromandibular triangle (lat. fossa retromandibulāris, English retromandible fossa) is an anatomical structure located on the lower jaw. It is a depression in the lower part of the face that is located between the jaw and the base of the skull. Retromandibular fossae play an important role in maxillofacial surgery and dentistry, as they can be used to access the mandibular canal and its contents.

The retromandibular fossa is formed by two surfaces, which are located on the lower jaw and on the base of the skull. On the lower jaw it is limited by the lateral pterygoid muscle and the large masseter muscle. At the base of the skull, the retromandibular fossa is limited by the maxilla and the sphenoid bone.

The retromandibular fossa contains important structures such as the mandibular canal, mandibular artery, mandibular nerve, mandibular veins and other anatomical structures. Through the retromandibular fossa, these structures can be accessed for surgical procedures or treatment of diseases. Also, retromandibular fossae can be used in dentistry for tooth extraction and other procedures.

Thus, the retromandibular fossa is an important anatomical formation that plays an important role in maxillofacial and dental practice.



The retromandular fossa is a small but anatomically important structure in the human body. This is a hole in the upper jaw, located behind the teeth and close to the ear area. This area has important functions for maintaining the health of the teeth, ears, face and brain. The retromandine fossa serves to hold the mandibular bone (mandibula) and support it during speech and chewing. The lower edge of the alveolar processes has a notch called the retromandibular fossa and is occupied by the premanandibular muscle.

The mandibular fossa performs many functions: - Holds the mandibular



The retromandylar fossa, or fossa of Francesco Sirel, is the area between the attachment of the mylohyoid muscle to the body of the mandible and the pterygoid process of the body of the scapula. The retromallibular fossa is located between the digastric bone and the tendon of the jaw muscle. The two muscles whose injury is associated with facial paralysis are located in the lower, upper part of the oral cavity.

The retromandylobural fossa is located in the lateral wall of the pharynx. The phrenological fossa of Francesco Serale is located under the superciliary arch and on the forehead
