Mandibular Coronoid Process Hypertrophy: Diagnosis and 20-Year Follow-Up with CBCT, MRI and EMG Evaluations

Abstract

Coronoid process hypertrophy (CPH) consists of an abnormal volumetric increment of the mandibular coronoid process; as this process grows gradually, the infratemporal space needed for the rotation and translation of the mandible is reduced, which results in a reduction of the range of mouth opening and lateral excursion, limiting mouth opening. The purpose of this case report was to describe a rare case of hypertrophy of coronoid processes with associated temporomandibular ankylosis, monitored for over 20 years. The patient was first visited when he had a facial trauma at the age of 4. Then he was followed through clinical, functional, instrumental, bi-dimensional and three-dimensional radiological evaluations up to the age of 24. Physical therapy was initiated at the age of 10 to improve the condition of the masticatory muscles, while at the age of 14, Transcutaneous Electrical Nerve Stimulations were performed to reduce muscle tension and, a bite plane was delivered to control the parafunctional activity of the jaw in the night and self-control instruction was provided for daytime habits. The adult patient has not accepted surgical intervention; thus, the future objective is to continue monitoring over the years to avoid a detrimental progression of the medical condition through physical and functional therapies while waiting for patient consent to surgery if needed.

“…The risk of bruxism also increases in general anxiety cases and during particularly stressful periods. TMD and bruxism are frequently associated with orofacial pain, reductions in articular mobility, and even pain in physiologic mandibular movements [ 55 , 56 , 57 ]. Bruxism is frequently associated with the presence of non-carious cervical lesions that may cause hypersensitivity [ 58 ], which increases the patient’s stress and affects the patient’s quality of life.…”

A Brief Review on Micro-Implants and Their Use in Orthodontics and Dentofacial Orthopaedics

“…For future practice, we can try the mini-implant anchorage in the mechanics of reducing the displacements of the temporomandibular discs [72], in the reposition of the mandible [73], in solving complicated problems such as cranial asymmetries with dentofacial and occlusal effects [74], in orofaciodigital syndrome treatments [75], and as a nonsurgical alternative in progressive ankylosis of the temporomandibular joint when patients do not accept the surgical treatment [76].…”

“…A combination of clinical features and typical image findings on plain radiographs, computed tomography (CT), and magnetic resonance imaging (MRI) is adequate for a reliable diagnosis in most cases [ 3 ]. Concerning the imaging method, it has also been widely used for the diagnosis of various illnesses [ 4 , 5 , 6 ]. Typically, patients with osteoid osteoma experience severe pain at night, which often responds effectively to nonsteroidal anti-inflammatory drugs (NSAIDs) [ 7 ].…”
