Assessment of Nasal Septum Change after Le Fort I Osteotomy Using Cone Beam Computed Tomography.

Objective: Le Fort I osteotomy (LF-IO) is widely used for the correction of dentofacial deformities, which may cause changes in the postoperative nasal septum (NS). The objective of this study was to evaluate the effects of LF-IO on the NS deviation and to determine whether the NS was affected by differences in the direction of maxilla movement.

Materials And Methods: A retrospective study including 57 patients who underwent LF-IO and received cone beam computed tomography (CBCT) preoperatively and 6-12 months postoperative evaluation was performed.

Factors affecting the relapse of maxilla and soft tissues of nose, upper lip and velopharyngeal structures after maxillary advancement in cleft patients.

The objectives of this study were to find the factors affecting the relapses after maxillary advancement in cleft patients. This retrospective study included 25 cleft patients. The serial lateral cephalograms were used for the evaluation of the maxilla and the soft tissue relapses in 1-year post-operative period.

Donor site morbidities of concha cartilage harvesting using a retroauricular approach for cleft rhinoplasty: retrospective study.

Objectives: Concha cartilage is recommended for correction of cleft nasal deformities. Morbidities at the donor site have been reported in esthetic rhinoplasty cases. Reports on cleft patients are limited, so we investigated the complications of concha cartilage harvesting using the retroauricular approach in cleft rhinoplasty and their management.

Three-Dimensional Analysis of Definitive Secondary Unilateral Cleft Rhinoplasty Using Cartilage Graft.

Objective: Three-dimensional assessment of nasal morphology in patients with unilateral cleft lip nose treated by cartilage graft augmentation.

Design: Retrospective study.

Patients And Intervention: Thirteen patients with unilateral cleft lip nose underwent definitive secondary rhinoplasty and postsurgical changes were examined using a three-dimensional (3D) laser scan.

Pre- and peri-operative factors influence autogenous tooth transplantation healing in insufficient bone sites.

Background: The amount of bone remaining at the transplant site for autogenous tooth transplantation can facilitate successful healing. Therefore, this retrospective study evaluated the factors influencing the healing of 50 successful autogenous tooth transplantations with insufficient bone support at the transplanted site without a bone graft.

Methods: The factors were classified as pre- and peri-operative factors, and the healing outcomes were clinical and radiographic observations.

Treacher Collins syndrome: Orthodontic treatment with mandibular distraction osteogenesis and orthognathic surgery.

Interdisciplinary treatment for patients with Treacher Collins syndrome is challenging because of the rarity of the condition and the wide variety of phenotypic expression. A 23-year-old male was diagnosed with Treacher Collins syndrome with a history of severe obstructive sleep apnea. He presented with a Pruzansky-Kaban classification grade I mandible, skeletal type II pattern with a hyperdivergent mandibular plane, severe convex profile, and Class II malocclusion with a missing mandibular incisor.

Alveolar cleft bone grafting: factors affecting case prognosis.

Objectives: The goal of this retrospective study was to determine the significance and impact of several factors on the alveolar cleft bone grafting procedure.

Materials And Methods: The medical records were reviewed. In addition, x-rays were checked.

Physicochemical and osteogenic properties of chairside processed tooth derived bone substitute and bone graft materials.

To analyze physicochemical such as surface structures, the crystallinity, chemical composition, calcium phosphate dissolution and osteogenic properties of tooth derived bone substitute (TDBS) processed chair-side and other grafting materials. The number of anaerobic and facultative anaerobic bacteria in the supernatant of processed TDBS was determined. Human osteoblasts were co-cultured with TDBS or allograft in transwell system to examine cell migration.

The anesthetic efficiency of retromolar infiltrations with two local anesthetic solutions of the same concentration in lower third molar surgery.

Background: Mandibular third molar removal is the most common surgical procedure encountered in oral and maxillofacial clinics. It also presents the greatest challenges and controversies for surgeons when surgical removal is considered. Furthermore, diverse anesthesia results and success rates are achieved after using the same concentrations of different solutions or the same amounts of local anesthetics.

Hemodynamic changes and pain perception-related anxiety after experiencing an impacted-tooth removal: clinical practice outcome.

Background: Dental fear is usually associated with hemodynamic changes. Fear of pain during the surgical removal of a lower impacted third molar might cause patients anxiety, thereby leading to avoidance of any future dental therapy. This study aimed to determine the effect of experiencing a surgical impacted-tooth removal on the pain perception-related anxiety and hemodynamic status.

Decreased post-operative pain using a sublingual injection of dexamethasone (8 mg) in lower third molar surgery.

Background: Every patient who undergoes mandibular third molar surgery is concerned about post-operative pain. Indeed, previous researchers have used various methods to treat such pain. This study aimed to assess the effectiveness of sublingual injection of dexamethasone (8 mg) to treat post-operative pain after mandibular third molar surgery.

4% lidocaine versus 4% articaine for inferior alveolar nerve block in impacted lower third molar surgery.

Background: No study has compared lidocaine with articaine, each at a concentration of 4% and combined with epinephrine. The purpose of this study was to compare the effectiveness of 4% lidocaine with that of 4% articaine, with a concentration of 1:100,000 epinephrine added to each, in an inferior alveolar nerve block for surgery on impacted lower third molars.

Method: This study was conducted at the Faculty of Dentistry, Mahidol University in Bangkok, Thailand.

The efficacy of dexamethasone injection on postoperative pain in lower third molar surgery.

Background: Surgery on the lower impacted third molar usually involves trauma in the highly vascularized loose connective tissue area, leading to inflammatory sequelae including postoperative pain, swelling, and general oral dysfunction during the immediate post-operative phase. This study aimed to investigate the effectiveness of preoperative injection of a single dose of 8 mg dexamethasone for postoperative pain control in lower third molar surgery.

Methods: A controlled, randomized, split-mouth, prospective study involving lower third molar surgery was performed in 31 patients.

Two unique cases of calcifying cystic odontogenic tumor in the maxillary posterior region.

A calcifying cystic odontogenic tumor (CCOT) is an uncommon odontogenic tumor with a predilection for the anterior part of the jaws. We report on 2 cases of CCOT in the posterior maxilla involving the maxillary sinus. In the first case, conventional radiography found a well-defined unilocular lesion.

Effect of single dose preoperative intramuscular dexamethasone injection on lower impacted third molar surgery.

This study aimed to investigate the effects of dexamethasone intramuscular injection 1h preoperatively, in reducing facial swelling, pain and trismus after lower impacted third molar (LITM) surgery. Twenty healthy Thai patients with both LITM surgical extraction were enrolled in the study. The washout period was 1 month after the first operation.
