Abstract
Mandibular fractures are frequently diagnosed in trauma centres. Tympanic plate and
mandibular fossa fractures can be associated with those fractures and can pass unnoticed
if a careful evaluation and adequate imaging exam are not performed. This descriptive
study was made to evaluate the incidence of condylar fractures associated with mandibular
fossa and/or tympanic plate fractures in a large trauma hospital. Twenty-nine patients
were diagnosed with such fractures between July/2019 and July/2020. A total of 81.5%
of the patients were diagnosed with condylar fracture associated with tympanic plate
fracture, 11.1% with a condylar fracture with mandibular fossa fracture, and 7.4%
with condylar fracture associated with both tympanic plate and mandibular fossa fracture.
Otorrhagia, trismus, malocclusion, and mouth opening deviation were the most observed
clinical signs. Treatments performed were speech therapy, open reduction, and closed
reduction. A total of 7.4% of the patients evolved with complications after the treatment.
This study suggests that fractures of the tympanic plate and mandibular fossa may
go unnoticed if an adequate imaging exam is not performed and rated by the surgeon.
The early and corrected treatment prevents future sequelae, and a long-term follow
up is essential.
