Introduction
Mandibular coronoid hyperplasia is when the mandibular coronoid process is longer than normal. This structure is histologically not
different from normal bone. These rare pathology symptoms are similar to temporomandibular joint diseases. Elongated coronoid
process, during coronoidectomy, temporalis muscle fibers are dissected and then resected and the resected part is removed. In
coronoidotomy, the coronoid process is resected and left in place.
Cases
Case 1:The patient applied to our clinic with increasing mouth restriction. As a result of clinical and radiological examinations performed
by us, the patient was diagnosed with mandibular coronoid hyperplasia. The patient was operated under general anesthesia.
Coronoidectomy was performed. Then the patient was awakened and the service was sent without any problems.
Case 2:The patient applied to our clinic with mouth restriction. As a result of clinical radiological examinations performed by us, the
patient was diagnosed with mandibular coronoid hyperplasia.The patient was operated under general anesthesia. Coronoidotomy was
performed. Then the patient was awakened and sent to the service without any problem.
Conclusion
In patients with restricted mouth opening and malocclusion, the first pathology that comes to mind is TMJ pathologies. After
inadequate examination and evaluation, wrong diagnosis is made and wrong treatments can be done. In such cases, the use of
orthopantomography, as well as three-dimensional tomographic method, is important in reaching the correct and definitive diagnosis
and in pre- and post-operative evaluation. In the treatment of these patients, coronoidectomy or coronoidotomy procedures are
performed.
