Symptoms of a cleft jaw

summary

The mandible is located in the lower 1 / 3 of the face, the position is prominent, easy to be hit and injured, the mandible bone is solid, but there are several anatomical weak areas, under direct or indirect violence, it is easy to fracture in these parts. Because mandible is the only active bone in maxillofacial region and participates in the formation of temporomandibular joint, it has great influence on masticatory function after injury. The symptom of cleft chin? Let's talk about it

Symptoms of a cleft jaw

Acute symptoms and signs: after mandibular fracture, pain, swelling and subcutaneous ecchymosis appeared at the fracture site. Gingival tear and tooth injury: gingival tear and bleeding around the fracture line in the mouth, and tooth loosening, fracture, displacement, etc.

Fracture segment displacement and abnormal mobility: after mandibular fracture, many factors can lead to fracture segment displacement, and masticatory muscle traction is the main factor causing fracture segment displacement. When the fracture displacement occurs, the abnormal motion of the fracture segment at both ends of the fracture site, and bone frications may appear at the fracture site during examination.

Occlusal disorder: after mandibular fracture, teeth move with the displacement of fracture segment, resulting in occlusal disorder. Dysfunction: the main manifestation is limited mouth opening, which affects the normal eating and language function. The degree of limited mouth opening depends on the fracture site and injury severity.

matters needing attention

Antibiotics should be used for 1-3 days after operation. Penicillins and cephalosporins can be selected as antibiotics. If the occlusal relationship is not good after operation, elastic traction of the upper and lower jaw can be considered for 1-2 weeks. If there is limitation of mouth opening due to muscle injury after operation, it is suggested to carry out mouth opening training as soon as possible to improve mouth opening degree. Postoperative reexamination and imaging examination were recommended for 3 months to observe the fracture healing. It is necessary to remind patients to have a reasonable diet and recover the occlusal function step by step.
