Background: Patients with limited mouth opening (LMO) often associated with difficult intubation. Retrograde intubation is an alternative technique of establishing definitive airway in these patients when blind nasal intubation fails and fiberoptic bronchoscope is not available. We tested the retrograde intubation through nasal route in patients with LMO less than 2 cm. Materials and methods: The procedure was performed with some modification with regard to retrograde guide on 18 patients requiring maxillofacial surgical procedures to increase mouth opening...

Large, benign intramandibular lesions are frequently removed by resection followed by extensive free tissue transfer or delayed bone grafting. We outline a protocol to remove benign mandibular lesions using sagittal split osteotomy (SSO) with virtual surgical planning (VSP) to mitigate risks involved with this effective, tissue-saving approach. Patients with benign mandibular lesions accessed by SSO with VSP during 2014 were included in this study. Computed tomographic data were imported into VSP software. Using VSP, the exact locations of mandibular lesions and the inferior alveolar nerve canal were delineated...

Trauma to the mandible can occasionally be a life-threatening event. Although extremely rare with only 56 reported patients in the English language, fracture of the floor of the middle cranial fossa with protrusion of the mandibular condyle into the middle cranial fossa was first reported in 1963 by Dingman. The authors review the anatomy of the temporomandibular joint in relation to the middle cranial fossa and demonstrate the possible complications due to condylar intrusion with anatomical dissection.

Facial fractures can be potentially fatal in polytraumatized patients due to retropositioning tissues to upper airway obstruction. In the first aids, this situation can be reversed using a tracheostomy procedure to break out the airways. However, fractures leading to airway obstruction are rare and according to Richards Classification can be classified into 5 types. The purpose of this article is to report a clinical patient with a bilateral condylar and mandibular symphysis fractures that resulted in airway obstruction and severe mandibular rear projection...
