One complication that may be associated with this procedure is displacement of the tooth into the infratemporal fossa, an anatomical structure that contains the temporalis muscle, medial and lateral pterygoid muscles, the pterygoid plexus, the maxillary artery and its branches, the mandibular nerve and its branches, and the chorda tympani. The present case report illustrates delayed surgical removal of a maxillary third molar that was displaced into the infratemporal fossa, via the intraoral access and under local anesthesia. Despite the rarity of this complication, oral and maxillofacial surgeons should be aware of its management and able to choose the optimal technique, taking into account the patient's signs and symptoms as well as the knowledge and experience of the surgeon.

Often, the tumor-like lumps that characterize the disease appear suddenly. This condition causes loss of mobility to affected joints, including the inability to fully open the mouth, limiting speech and eating; a specific occurrence of this condition to the foot joints can result in limited ability of the FOP patient to put a foot flat on the ground.
Bone growth can also result in the immobilization of the hip or knee, also limiting the individual's ability to walk. Extra bone formation around the rib cage restricts the expansion of lungs and diaphragm causing respiratory complications. Since the disease is so rare, the condition may be misdiagnosed as cancer or fibrosis. This leads physicians to order biopsies , which can exacerbate the growth of the FOP bone.
However, delayed diagnosis, trauma, and infections can decrease life expectancy. Most cases are caused by spontaneous mutation in the gametes ; most people with FOP cannot or choose not to have children. A similar but less catastrophic disease is fibrous dysplasia , which is caused by a post-zygotic mutation.

Introduction The most common procedure in oral and maxillofacial surgery is extraction of the third molar. The infratemporal fossa is an irregularly shaped space located below the greater wing of the sphenoid bone containing the foramen ovale , lateral to the ramus of the mandible and the gap between the zygomatic arch and temporal bone forming the communication to the temporal fossa.
The lateral pterygoid plate forms the medial margin while the maxilla forms the medial aspect of this space. The temporalis muscle, medial and lateral pterygoid muscles, pterygoid venous plexus, mandibular nerve and its branches, maxillary artery and its branches, and the chorda tympani nerve are all contained in the infratemporal fossa. There is no consensus in the literature or established management approach for displacement of the third molar into the infratemporal fossa.
Surgical and conservative approaches have been reported; the surgeon is expected to select the most appropriate strategy for each case. Recommended management steps include immediate surgical removal if possible, initial watchful waiting and delayed removal, or observation alone. Complications associated with the presence of the tooth in the infratemporal fossa include infection, limitation of mandibular movement, and psychological discomfort.
Sometimes, the displaced tooth may migrate inferiorly spontaneously and become accessible via the intraoral access.
After anamnesis, clinical and radiographic examinations Fig. One year later, extraction of the right maxillary third molar 18 was attempted.
During the procedure, this tooth was accidentally displaced into the adjacent anatomical space. The patient and her legal guardian were notified of the situation as soon as possible, and the decision was made to carry out further imaging to support case planning.
Histological analysis Fig. Although relatively minor injury by PBS injection is not sufficient to stimulate heterotopic ossification, our results show that more severe connective tissue injury in the context of the RH mutation triggers a severe inflammatory response that is followed by development of heterotopic ossification.
Figure 5 Open in figure viewer PowerPoint Cells participating in heterotopic lesion formation. Skeletal muscle and areas of heterotopic ossification, similar to Fig. Double positive cells are observed in all stages of lesion development and were the most abundant cells present also see Supplemental Fig. Discussion Animal models of human genetic disease are vital for validating the exact genetic cause of a condition, for understanding the cellular and molecular mechanisms of disease pathology, and for developing translational strategies to prevent and treat affected individuals.
Along with progressive heterotopic endochondral ossification, malformation of the great toes is a hallmark of classic FOP.
No malformations were seen in the fore limb digits of any of the chimeras. The study reveals that heterotopic ossification in FOP is not simply a process of ectopic bone formation within skeletal muscle. Rather, the original skeletal muscle tissue is replaced with heterotopic bone in a complex multistage process characterized by an inflammatory and apoptotic catabolic phase, followed by an anabolic endochondral phase.
These findings establish that heterozygous substitution of c. This work sheds light on many important questions about the cellular targets of the FOP mutation, including those that could only be addressed in viable chimeras exhibiting the classic FOP phenotype.
