Abstract

Heterotopic ossification (HO) is usually seen after-trauma, following traumatic injuries, surgeries involving major joints, neurogenic injury, and burns; however, atraumatic cases have also been reported. HO tends to cause pain, swelling, and limitation of joint movements. HO has been reported in adults as well as in pediatric cases, however, our search in the English literature has not revealed a single case in the infratemporal region, especially in children of developing age, where HO tends to affect the development and growth of adjacent bones. We are reporting a case of HO in close proximity to TMJ affecting the development of mandible and maxilla.

Highlights

Heterotopic ossification is the formation of mature lamellar bone in soft tissues outside the joint capsule and periosteum
Heterotopic ossification (HO) can occur in pediatric age group in the maxillofacial region and affect the development and growth of the TMJ
History of trauma and symptoms like pain, swelling, and limited range of motion related to HO may or may not be present

Summary

Introduction

Heterotopic ossification is the formation of mature lamellar bone in soft tissues outside the joint capsule and periosteum. HO usually occurs secondary to trauma and has been frequently reported after hip arthroplasty and spinal injury. It is usually symptomatic, and patient presents with pain and swelling. Cases showing limited range of motion, due to presence of HO in close proximity to joint, have been reported. Literature has not revealed HO affecting the TMJ and its development. A case of one such patient, where HO occurred in close proximity to TMJ affecting its function and growth of maxilla and mandible, is reported. The incomplete development of maxilla and mandible resembles a mild case of Goldenhar syndrome. Until further evidence disproves this, this may be considered first such case of Goldenhar syndrome with HO
