Submental intubation in oral maxillofacial surgery : review of the literature and analysis of 13 cases
Objectives: Various different methods of intubation are suitable for facial trauma cases. A choice often has to be made between orotracheal and nasotracheal when surgical access to the nasal or oral cavity is necessary. This work presents our current experience using submental intubation in the airway management of facial trauma patients. Study design: From July 2003 to February 2005, 13 sufferers from facial trauma benefited from submental intubation. All the patients were males and the ages ranged from 19 to 35 years (mean, 27 years). Results: In all the patients, the submental intubation permitted simultaneous reduction and fixation of all fractures and intraoperative control of the dent…
Facial nerve paralysis after impacted lower third molar surgery: A literature review and case report
Facial nerve paralisys (FNP) is the most commom cranial nerve disorders and it results in a characteristic facial distortion that is determined in part by the nerves branches involved. With multiples etiologies, these included trauma, tumor formation, idiopathic conditions, cerebral infarct, pseudobulbar palsy and viruses. FNP during dental treatment is very rare and can be associated with the injection of local anesthetic, prolonged attempt to remove a mandibular third molar and subsequent infection. We report a case of a 21 years-old black woman who developed a Bell?s palsy after an impacted third molar surgery under local anaesthesia, present a FNP classificated like a grade IV by the Ho…
Surgical treatment of temporomandibular joint ankylosis : follow-up of 15 cases and literature review
Introduction: Ankylosis may be defined as the fusion of the articular surfaces with bony or fibrous tissue. The treatment of temporomandibular joint ankylosis poses a significant challenge because of the high incidence of recurrence. Purpose: To report 15 cases treated by either gap arthroplasty, or the articular reconstruction technique using costochondral grafts, coronoid process grafts or alloplastic condylar implants; evaluate the results of these surgeries and make a literature review. Methods: The sample was obtained from the records of the Oswaldo Cruz University Hospital (HUOC-UPE) of patients submitted to ankylosis treatment by alloplastic or autogenous graft between March 2000 and…
Glove perforation during oral surgical procedures
Objective: The aim of this study was to determine the incidence of glove perforation among undergraduates and residents performing maxillofacial surgery and identify procedures associated with the perforations. Study Design: For this purpose, 200 pairs of surgical gloves were used. For inspecting the perforations, the gloves were filled with water, at least 500 ml. Results: Sixteen gloves (8%) were perforated, 8 (4%) by residents and 8 (4%) by undergraduate students. Only the residents noticed that 2 gloves (1%) were perforated and identified the object causing the perforation. The left hand was the more affected with 9 perforations (4.5%). The finger pulp was the region most affected with …
Evaluation of lidocaine and mepivacaine for inferior third molar surgery
Objective: The aim of this study was to compare 2% lidocaine and 2% mepivacaine with 1:100,000 epinephrine for postoperative pain control. Study design: A group of 35 patients, both genders were recruited, whose had ages ranged from 13 to 27 years-old and had two inferior third molars in similar positions to be extracted. The cartridges were distributed to the patients according to a randomised pattern, where lidocaine was in the control group and mepivacaine in the experimental group. Results: Results showed no significant association between the anesthetics and postoperative pain, pulp sensibility after one hour, gender, tooth position and duration of the surgical procedure. Conclusions: …
Influence of local anesthethics with adrenalina 1:100.000 in basic vital constants during third molar surgery
Objective: The present study consists of a double-blind randomized clinical trial of paired samples. The purpose of the present study was thus to examine the effect of four different local anesthetics of the amida group (2% lidocaine with 1:100.000 adrenaline; 3% prilocaine with 0.30 IU felipressine; 2% mepivacaine with 1:100.000 adrenaline; and 4% articaine with 1:100.100 adrenaline) in patients undergoing extraction of lower third molars and verify the changes in systolic, diastolic and mean blood pressures, heart rate (HR) and oxygen saturation (SpO2 ). Study design: The sample comprised 168 extractions of lower third molars performed on 84 patients, divided into three groups, in whom li…
Facial nerve injury following surgery for the treatment of ankylosis of the temporomandibular joint
Objective: The purpose of the present paper was to carry out a longitudinal study of a series of cases in which injury of the facial nerve was observed following surgery for the treatment of temporomandibular ankylosis. Study design: The sample was composed of 13 patients, both male and female, in whom 18 surgical approaches were made. A postoperative assessment of the motor function of the facial nerve was made in accordance with the HouseBrackmann grading system. All the patients were photographed and assessed at the following postoperative times: 24 hours, one week, one month and three months. Results: The results showed that injury of the facial nerve occurred in 31% of the cases. An in…
Physical therapy and anesthetic blockage for treating temporomandibular disorders: a clinical trial
Purpose: the aim of this study was to evaluate the use of physical therapy and anesthetic blockage of the auriculotemporal nerve as a treatment for temporomandibular joint disorders. Methods: the sample comprised of twenty patients with a diagnosis of disc displacement with/ without reduction and arthralgia according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD Axis I Group IIa, IIb and IIIa). Ten patients (group 1) underwent a cycle of eight anesthetic blockages of the auriculotemporal nerve with injections (1 per week) of 1 ml of bupivacaine 0.5% without vasoconstrictor for 8 weeks. The other 10 patients (group 2) received anesthetic blockage and physical t…
Frequency of positive aspirations in anesthesia of the inferior alveolar nerve by the direct technique
Objectives: Evaluate the frequency of positive aspirations and complications resulting from anesthesia of the inferior alveolar nerve by the direct technique. Study design: The sample was composed of 138 anesthetic injections applied with Duflex syringes with reflux. The anesthesia was applied in patients of both sexes of various ages for procedures in which such anesthesia would be necessary. Results: The results showed 4.3% of positive aspirations in vivo. When the percentages of positive aspiration on the right and left sides were compared, no significant association was found. A greater number of positive aspirations was observed in the 15-30-year-old age group. It is emphasized that th…
