Blunt maxillary fracture and cheek bite: two rare causes of traumatic pneumomediastinum
No full textSubcutaneous facial emphysema is a well-known consequence of oral and maxillofacial traumatic injury. In some rare cases, the subcutaneous air collection could spread through the retropharyngeal and paralatero-cervical spaces, reaching the mediastinum. This clinical entity is known as pneumomediastinum and represents a severe and, sometimes, life-threatening condition. Other reported causes of pneumomediastinum are esophageal and tracheal traumatic or iatrogenic rupture. Finally, the so-called spontaneous pneumomediastinum is caused by a sudden increase in alveolar pressure and is usually seen in young men. We present two cases of pneumomediastinum as a consequence of unusual traumatic damage of orofacial tissues, followed by repeated sneezing and Valsalva maneuver

A Dental Implant in the Infratemporal Fossa: Case Report
No full textImplant-supported prosthetic rehabilitation represents
one of the most common procedures in dental
clinical practice.1 The recent development of computer-
aided design/computer-assisted manufacture technology
for surgical planning and fabrication of custom
surgical templates has led to minimally invasive, valid,
and simplified surgical approaches.2,3 Preoperative
computer-guided three-dimensional planning of implant
treatment takes into account bone quality and
quantity and can therefore avoid bone augmentation
procedures in many patients with atrophied jawbone.
2,4 However, accurate implant planning and strict
adherence to standardized surgical protocols is mandatory
to minimize the risk of complications during the
surgical phase.4 Intraoperative implant displacement
into the paranasal sinuses has been reported frequently.
5–10 Any surgical treatment that includes the posterior
maxillary region, whether for dental placement or
extraction of third molars, has to take into account the
maxillary sinus because of its anatomical position.11
Infratemporal fossa involvement is less common after
implant surgery or exodontia, and it is usually associated
with an inaccurate preoperative evaluation or an
incorrect inclination of the pterygoid implant during
its insertion.12,13 To the authors’ knowledge, this is the
first report of dental implant dislocation during computer-
assisted implant positioning
A dental implant in the infratemporal fossa: case report.
No full textThis case report describes a rare displacement of a dental implant in the infratemporal fossa, which occurred during placement of the implant into the pterygoid process with computer-assisted technology. The implant was immediately removed by means of an intraoral approach to prevent any neurologic complications. Although computer-aided systems in implant surgery represent a reliable and effective tool, the surgeon should always instruct the patient on the necessary behavior during implant placement and the risks associated with a lack of adherence to these recommendations
Fresh-frozen human bone graft to repair defect after mandibular giant follicular cyst removal: a case report.
No full textThe purpose of this article is to report the clinical, radiographical and histological findings about a case of a young woman affected by a mandibular giant follicular cyst. Conservative tumor resection was followed by immediate reconstructive treatment using fresh frozen human bone graft, instead of autologous bone graft, as material for bone regeneration. Follicular cyst is a benign, non invasive lesion with slow but progressive growth. Radiological and histological examination of the lesion confirmed the presence of a follicular cyst which underwent biopsy evaluation before enucleation. According to literature, conservative treatment was performed with optimal prognosis. At 24 months post surgery no evidence of recurrency was objective; the CT scan revealed optimal bone formation inside the reconstructed site. The use of fresh frozen bone allograft, thanks to its osteoinductive and osteoconductive properties, can be a safe choice for reconstruction of bone defects after jaw cysts removal
