BACKGROUND In Asian countries, many patients with a prominent mandibular angle desire its correction, because they consider it to be an unappealing feature. Reduction mandibuloplasty has been frequently performed through the intraoral approach, but an invisible mandibular angle forces the surgeon to perform blind ostectomy. In addition, the limited mobility of the oscillating saw leads to semi-...

BACKGROUND The boundaries for orthodontic tooth movement are set by the bony support of the dentition. This study compares the mandibular anterior alveolar housing in individuals with low, average, and high mandibular plane angles before orthodontic treatment and measures alveolar bone loss and root resorption after orthodontic treatment. METHODS Pretreatment cone-beam computed tomography (CB...

AIM The gonial angle plays an important role in ensuring a harmonious facial profile. Changes in this angle after surgery may be an esthetic concern for both the patient and the surgeon. The aim of the present study was to evaluate gonial angle changes after mandibular setback by the bilateral sagittal split osteotomy (BSSO) and vertical ramus osteotomy (VRO) techniques. METHODS Fifty-eight m...

PURPOSE The aim of the present study was to evaluate the potential morphologic risk factors for postoperative neurosensory disturbance (NSD) after bilateral sagittal split osteotomy. PATIENTS AND METHODS The study subjects were 30 skeletal Class III patients (9 males and 21 females), with a mean age of 22.0 years (range, 16-39 years). All patients underwent bilateral sagittal split osteotomy ...

OBJECTIVE To compare the positions of the mandibular premolars in Angle Class I subjects according to vertical facial type. The results will provide a theoretical basis for predicting effective tooth movement in orthodontic treatment. METHODS Cephalometric parameters were determined using cone-beam computed tomography in 120 Angle Class I subjects. Subjects were categorized as short, normal, ...

Forty-five patients with mandibular retrognathism treated by surgical mandibular advancement by sagittal split osteotomies were evaluated cephalometrically before treatment at the intermaxillary fixation release, and 6 months postoperatively. The treatment resulted in appreciable improvement of the mandibular retrognathism, and the facial morphology was changed positively toward normal values. ...

Cerebral localization of the larval form of Echinococcus granulosus is a rare occurrence (1-4% of cases of hydatidosis) [1 ] , and usually produces solitary large unilocular (hydatid) cysts located in the supratentorial compartment [2-4]. We report the plain and contrast-enhanced MR appearance of a histologically proved pontine hydatid cyst that was adjacent to a multicystic acoustic neurinoma ...

OBJECTIVE To evaluate the treatment effects and stability of Forsus appliance therapy. METHODS Thirty-one patients (15 males, 16 females) with a mean age of 15.8 +/- 3.1 years (range 13 to 17.6 years, 15.3 +/- 1.2 years for females and 16.5 +/- 1.6 years for males) were selected. All patients had passed beyond their pubertal growth phase (after CS4 or MP3cap). Lateral cephalograms and threedi...

The goal of the study was to analyse statistically the survey of measurable parameters distinguishing human facial skeleton as well to construct mathematical model describing foetal facial skeleton selected features. The material consisted of 112 foetuses (44 females – 39.29% and 76 males – 60.71%) in the CRL: 83-245 mm, aged 4-7 months of foetal life. The whole of the examined material origina...
