What are the risk factors for postoperative infections of third molar extraction surgery: A retrospective clinical study-?
2018
Background This study aimed to identify (1) the predilection site of postoperative infection after third molar extraction surgery, (2) risk factors associated with postoperative infection, and (3) the cause of the difference between delayed- and early-onset infections. Material and Methods This retrospective study included 1010 patients (396 male, 614 female) who had ≥1 third molars extracted (2407; 812 maxilla, 1595 mandible). The risk factors were classified as attributes, general health, anatomic, and operative. Outcome variables were delayed- and early-onset infections. Results Postoperative infection was completely absent in the maxilla, and all infections occurred in the mandible, wit…
The Role of Third Ventriculostomy in the Management of Obstructive Hydrocephalus
2003
Objective: Endoscopic third ventriculostomy (ETV) is an effective treatment for occlusive hydrocephalus caused by an obstruction of the CSF flow in the aqueduct or the posterior fossa. We evaluated the factors age, pathology and surgical technique on the results of the ETV. Methods: Between November 1992 and October 2000 171 ETV have been performed in 159 patients. The follow-up was evaluated in 150 patients. The age ranged from 10 days to 77 years (mean age 35 years). The hydrocephalus was caused by benign aqueductal stenosis in 77 patients, space-occupying lesions in 59, by intraventricular hemorrhages in 11, and by other causes in 3 patients. The trajectory was planned in 31 patients by …
Non surgical predicting factors for patient satisfaction after third molar surgery
2016
Background: In the third molar surgery, it is important to focus not only on surgical skills, but also on patient satisfaction. Classically studies have been focused on surgery and surgeon’s empathy, but there are non-surgical factors that may influence patient satisfaction. Material and Methods: A cross-sectional study was performed on 100 patients undergoing surgical extractions of impacted mandibular third molars treated from October 2013 to July 2014 in the Oral Surgery Unit of the University of Valencia. A questionnaire (20 questions) with a 10-point Likert scale was provided. The questionnaire assessed the ease to find the center, the ease to get oriented within the center, the burocr…
Endoscopic aqueductoplasty through a tailored craniocervical approach.
2005
Object. Neuroendoscopy has an essential role in the management of occlusive hydrocephalus due to a membranous obstruction of the sylvian aqueduct. Well-known endoscopic methods include endoscopic third ventriculostomy (ETV) and endoscopic aqueductoplasty through a frontal burr hole. Building on their experience in the endoscopic management of hydrocephalus, the authors realized that not all of their patients with aqueductal obstruction were eligible for the aforementioned lines of treatment. Certain anatomical situations made it impossible to perform ETV or endoscopic aqueductoplasty through a frontal burr hole. Long-term complications of the shunt system led the authors to seek an alternat…
Post-traumatic trigeminal neuropathy. A study of 63 cases.
2010
Introduction. Trigeminal neuropathy is most often secondary to trauma. The present study explores the underlying causes and the factors that influence recovery. Material and methods. A retrospective case study was made involving 63 patients with trigeminal neuropathy of traumatologic origin, subjected to follow-up for at least 12 months. Results. Fifty-four percent of all cases were diagnosed after mandibular third molar surgery. In 37 and 19 patients the sensory defect was located in the territory innervated by the mental and lingual nerve, respectively. Pain was reported in 57% of the cases, and particularly among the older patients. Regarding patient disability, quality of life was not a…
The effects of informed consent format on preoperative anxiety in patients undergoing inferior third molar surgery
2013
Objectives: To evaluate the effect of informed consent format on preoperative anxiety of patients. Material and Methods: We performed a prospective study (91 patients) undergoing lower third molar extraction. Patients were distributed into three groups. Informed consent for surgery was obtained through a written document, an oral interview or a video recording. Afterwards, patients were asked about their anxiety level and the effect the informed consent had had on it. Results: Whereas the information conveyed both in oral and written formats relieved the patient to some extent (in a scale of -3 to +3) 0.97±1.21 and 0.29±0.97, respectively), the video recording increased patient’s anxiety in…
Predicted and actual fetal weight throughout the last trimester.
1997
The aim of our study was to obtain, in normal pregnancies, references values of predicted and actual fetal weight for both male and female fetuses and for fetuses born to nulliparous and multiparous women between weeks 28 and 41 of gestation. Predicted fetal weight curves represented calculations of weight in the third trimester based on weight data obtained during the second trimester. These curves were obtained from 134 ultrasonograms obtained between weeks 20 and 27. Actual fetal weight curves represented the values calculated from third trimester measurements and were based on 374 ultrasonograms obtained between weeks 28 and 41. For predicted fetal weight minor differences were found be…
Photobiomodulation therapy reduces postoperative pain after third molar extractions: A randomized clinical trial
2020
Background To assess the efficacy of PBMT on reducing postoperative pain scores in patients submitted to third molar extractions. Material and Methods A randomized controlled trial (ReBEC:RBR-94BCKZ) was designed according to the SPIRIT and followed the CONSORT. Patients were randomly allocated according to control or PBMT groups. PBMT consisted of the application of GaAlAs laser (808nm;50mW) applied in six points (1.23 min;11 J/cm2) after extraction. Pain scores were assessed using the Visual Analogue Scale (VAS) in millimeters evaluated after 6 (T6), 24 (T24), and 48 (T48) hours. The Wilcoxon Mann–Whitney test was used to check for possible associations between VAS scores and treatment gr…
Survey of Spanish dentists on the prescription of antibiotics and antiseptics in surgery for impacted lower third molars
2015
Background: This study explored the attitude of registered dentists in Biscay towards prescribing antibiotics and/ or antiseptics to prevent potential infections after surgical extraction of completely bone-impacted third molars in otherwise healthy individuals, with no history of infection. Material and Methods: We sent letters to 931 registered dentists in Biscay, with an explanation of the study objectives, description of a case of lower third molar impaction, including a panoramic radiograph, and a questionnaire. The questionnaire asked whether they would prescribe antibiotics and/or antiseptics, in the hypothetical case of lower third molar extraction surgery presented, and if so, when…
Effect of lingual-based flap design on postoperative pain of impacted mandibular third molar surgery : split-mouth randomized clinical trial
2020
Background The extraction of third molars is one of the most common procedures in oral and maxillofacial surgery clinic. Surgical extraction involves the manipulation of both soft and hard tissues, so the patient usually experiences pain, swelling, and trismus in the immediate post-operative period. Several studies have been conducted using different types of surgical flaps to provide access with the least possible damage of soft tissues. Designing and implementing an optimum flap, which provides easier technique, better visibility, minimal post-operative complications, and best healing, is an aspired goal of every oral surgeon. This study aimed to compare lingual-based four-cornered flap w…
