Objective The purpose of this case series was to assess the aesthetic and functional outcome of orbital floor reconstruction performed with calvarial bone graft, titanium mesh or prolene mesh. Methods Ten cases of orbital blowout fractures treated at our centre from October 2006 to July 2008 were considered for this study. Clinical examination, patient satisfaction and radiographic investigations were used to assess repaired fractures. Results Prolene mesh was used in four cases, titanium mesh was used in four cases and calvarial graft used in two cases. Nine patients had significant improvement in their esthetic appearance. Symmetry was restored in all cases. All ten cases had a noticeable improvement in the function. Of total ten cases six had diplopia, three recovered completely during the six months after the surgery. Three cases showed improvement later. All ten cases with enopthalmos recovered completely. Of the nine patients with infraorbital numbness, all recovered completely during the six months following surgery. One patient where the reconstruction was done with calvarial bone graft showed mild discrepancy in the ocular level. Conclusion For small, linear defects measuring less than 2cm with enopthalmos and restricted ocular movements, prolene mesh (four cases) was used. For larger defects and impure blowout fractures involving the infraorbital rim, calvarial graft (two cases) or titanium mesh (four cases) was used. The outcome of surgery with all three materials was satisfactory. No postoperative complications were seen except for mild hypoglobus in a case reconstructed with calvarial graft. All three materials, calvarial graft, titanium mesh, prolene mesh, have the potential to be useful reconstructive materials in orbital floor blowout fractures.
Submental intubation is an interesting alternative to tracheostomy, especially when short-term postoperative control of airway is desirable with the presence of undisturbed access to oral as well as nasal airways and a good dental occlusion. Submental intubation with midline incision has been used in 10 cases from October 2008 to March 2010 in the Department of Oral and Maxillofacial Surgery, Manipal College of Dental Sciences, Mangalore. All patients had fractures of the jaws disturbing the dental occlusion associated with fracture of the base of the skull, or/and a displaced nasal bone fracture. After standard orotracheal intubation, a passage was created by blunt dissection with a haemostat clamp through the floor of the mouth in the submental area. The proximal end of the orotracheal tube was pulled through the submental incision. Surgery was completed without interference from the endotracheal tube. At the end of surgery, the tube was pulled back to the usual oral route. There were no perioperative complications related to the submental intubation procedure. Average duration of the procedure was less than 6 minutes. Submental intubation is a simple technique associated with low rates of morbidity. It is an attractive alternative to tracheotomy in the surgical management of selected cases of panfacial trauma.
Introduction: This study was carried out to evaluate the effects of a single pre-operative sub-mucosal injection of dexamethasone after third molar surgery to see the effects on post-operative discomfort. Methods: This study was a prospective, double-blind, randomized, clinical trial. The subjects were forty patients who underwent surgical removal of the mandibular impacted third molar under local anesthesia and after being randomly assigned to receive either an 8 mg dexamethasone as submucosal injection or a normal saline injection into the lower buccal vestibule adjacent to the third molar. The maximum interincisal distance and facial contours were measured at the baseline and post-surgically on Day 2 and 7. Post-operative pain was evaluated subjectively using a visual analog scale and objectively by counting the number of analgesic tablets used. All subjects were operated upon by the same investigator to minimize the difference from inter-operator variability. Results: There was a signicant difference in the measurements of the degree of swelling and trismus between the two groups on the 2nd post-operative day. In contrast, there was no statistically signicant difference between the groups on the 7th post-operative day. The test group also used fewer analgesics post-operatively. Conclusions: Submucosal injection of dexamethasone after third molar surgery is effective in reducing postoperative swelling and trismus. It also delays the onset of post-operative pain.
