Congenital mandibular coronoid process hyperplasia and associated diseases

Area of Science:

• Oral and Maxillofacial Surgery
• Genetics
• Pathology

Background:

• Coronoid process hyperplasia (CPH) is an oral and maxillofacial surgical condition characterized by enlarged mandibular coronoid processes, leading to restricted mouth opening.
• Bilateral CPH is less common, often leading to misdiagnosis or delayed treatment.
• The exact etiology of congenital CPH remains unclear, though genetic factors are suspected.

Purpose of the Study:

• To examine the relationship between congenital mandibular CPH and associated diseases.
• To review clinical diagnosis and treatment strategies for CPH-related restricted mouth opening.

Main Methods:

• Case collection from clinical practice.
• Comprehensive literature review on CPH.

Main Results:

• CPH presents as painless, progressive restriction of mouth opening, unilaterally or bilaterally.
• Coronoidectomy demonstrates significant effectiveness in improving mouth opening.
• Congenital CPH is believed to have a genetic basis, though further research is needed.

Conclusions:

• CPH is a significant cause of restricted jaw mobility requiring accurate diagnosis.
• Coronoidectomy is an effective surgical intervention for CPH.
• Understanding the genetic links to congenital CPH is crucial for future research and treatment.
