The outcome of coronoidectomy in bilateral coronoid process hyperplasia

Abstract

Patients with limited jaw function related to bilateral CPH can benefit by undergoing bilateral coronoidectomies and physiotherapy.

The role of double‐step advancement genioplasty and bilateral coronoidectomy in Nager Syndrome: A case report

“…The disorder's clinical manifestations include unilateral or bilateral affection, none to mild pain, absence of occlusal abnormality, and progressive mandible depression capacity reduction 10,12,13 . In this case, the patient presented severe trismus without significant pain during function or occlusal abnormality.…”

Bilateral Elongated Mandibular Coronoid Process and Restricted Mouth Opening: A Case Report

“…The stability of the outcome, however, is considered questionable because of the risk of reattachment of the coronoid process [ 16 ]. However, coronoidotomy in combination with prolonged postoperative physiotherapy has demonstrated satisfying long-term results with substantial improvement in mouth opening [ 6 , 17 ]. Coronoidectomy is the most commonly used surgical method for MCPH involving surgical excision of the elongated coronoid process [ 18 ].…”

“…The unilateral form is often seen in females, whereas the bilateral form is more common in males [ 1 ]. The main clinical symptom of elongated mandibular coronoid process impinging upon the zygomatic bone is a progressive painless reduction in mouth opening [ 1 , 3 , 6 ]. On conventional radiograph imaging, MCPH usually presents as a hyperplastic coronoid process projecting into the infratemporal fossa.…”

“…Computed tomography is mandatory for accurately evaluation of the association between the hyperplastic coronoid process and the zygomatic bone, and thus plays an important role in diagnosing and planning the surgical treatment [ 7 , 8 ]. Coronoidectomy using an intraoral approach followed by vigorous long-term postoperative physiotherapy is the recommended treatment modality for MCPH with impingement on the zygomatic bone and limited mouth opening [ 6 , 9 - 12 ]. However, surgically induced fibrosis and the tendency for mandibular coronoid process regrowth may cause relapse and renewed limited mouth opening [ 3 ].…”

Mandibular coronoid process hyperplasia: a case report

“…The treatment of choice is the total or partial removal of the affected coronoid process(es) on the zygomatic arch through plastic surgery, if required. In addition, postoperative physical therapy is recommended after surgery [9][10][11][12][13][14] . Physical therapy is very important to obtain good results after the coronoidectomy and includes several therapeutic techniques involving spatula, wedge and the TheraBite Jaw Motion Rehabilitation System 15 .…”
