Comparison of the Effect of 2 Hypotensive Anesthetic Techniques on Early Recovery Complications After Orthognathic Surgery
(Lippincott Williams & Wilkins, 2012) Tabrizi, Reza; Eftekharian, Hamid Reza; Langner, Nicole Janine; Ozkan, Birkan Taha
The aim of this study was to evaluate the recovery complications following the use of 2 anesthetic protocols in orthognathic surgery, namely, propofol with remifentanil and isoflurane with remifentanil. Sixty-two patients with American Society of Anesthesiologists physical status I were selected. All underwent bimaxillary orthognathic surgery. Propofol with remifentanil was used as an anesthesia in group 1 (n = 32), and isoflurane with remifentanil was used in the patients in group 2 (n - 30). Early recovery complications consisting of pain, postoperative nausea and vomiting (PONV), shivering, and agitation were evaluated and documented. The length of the operation and duration of recovery were documented for all patients. Analysis of the data demonstrated no relationship between age and recovery time (P > 0.05). Analysis of data with chi(2) and independent t-tests did not show any difference between the 2 groups with regard to pain, agitation, PONV, and shivering (P > 0.05). Logistic regression was used to evaluate the effect of the operation time on recovery complications. The analysis showed that pain and PONV were significantly higher in those who experienced a longer operation time. With increasing operation time longer than 165 minutes, 64% of patients experienced pain, and 89% of them had PONV. General anesthesia can be provided via intravenously administered medications and/or inhaled volatile anesthetics. No significant difference in early recovery time was found in patients when either isoflurane or propofol was used to maintain the anesthesia. However, the length of the operation played a major role in increasing early recovery complications.
Marsupialization as a Treatment Option for the Odontogenic Keratocyst
(Lippincott Williams & Wilkins, 2012) Tabrizi, Reza; Ozkan, Birkan Taha; Dehgani, Ali; Langner, Nicole Janine
Background and Purpose: The odontogenic keratocyst (OKC) is an unusual cyst with a high recurrence rate. The most common site for OKCs is by far the mandible. The best treatment of OKC remains controversial. Recurrence rates ranging anywhere from less than 10% to more than 60% have been reported. The aim of our study was to evaluate marsupialization as a treatment option for OKC. Methods: We managed 13 patients (8 male, 5 female) between the ages of 16 and 31 years (mean, 22.4 y) with biopsy-proven OKC. Radiographically, the patients' cyst sizes were between 25 and 90 mm. Treatment consisted of marsupialization. We followed up with patients for a total duration of at least 60 months, and posttreatment visits were carried out at 6-month intervals. Results: We documented cured or reduced cyst size with radiography. The odontogenic keratocyst resolved completely in 10 patients, and the cyst walls shrank in 3 patients. The latter patients required a second operation to remove the associated impacted teeth. A histologic evaluation of 3 lesions showed metaplasia. Any case of recurring cysts was not seen during the entire follow-up period. Conclusions: Marsupialization is an effective and conservative treatment option for OKC. Nevertheless, future studies should conduct even longer follow-up periods to evaluate any recurrence of lesions.
