Gender-dependent impact of aging on facial proportions.

Purpose: Facial proportions in younger people have been evaluated in several studies. However, the number of older people who need orthognathic surgery is growing steadily. The aim of this study was to evaluate facial morphology in Caucasians accounting for age and gender.

A non-language-specific speech test to evaluate the speech of cleft patients from different language and cultural backgrounds - A pilot study.

Cleft speech tests are not universally available. We developed a tool to fill this gap, especially in the context of a cleft mission setting. We performed a pilot study to evaluate the test's ability to differentiate between the speech of cleft patients and healthy individuals from three different language backgrounds.

Use of anterior maxillary distraction osteogenesis in two cleft lip and palate patients.

Distraction osteogenesis (DO) has become a mainstream surgical technique for patients with jaw deformities. The aim of this study was to report the effect of DO done by a hyrax screw incorporated in an acrylic plate in the treatment of two maxillary deficient cases with cleft lip and palate. Two patients, a 24-year-old female and a 29-year-old male who suffered from maxillary deficiency and cleft lip and palate, were treated by DO.

Effect of maxillary advancement on the change in the soft tissues after treatment of patients with class III malocclusion.

The aesthetic outcome of treatment has become increasingly important to patients having orthognathic surgery. The aim of this observational cohort study based on clinical records was to evaluate the effect of maxillary advancement on changes to the soft tissues. We studied 53 patients with class III malocclusion (29 women and 24 men, mean (SD) age 28 (11) years).

Evaluation of soft and hard tissue changes after bimaxillary surgery in class III orthognathic surgery and aesthetic consideration.

Aims: The aim of this study was to evaluate hard and soft tissue change after bimaxillary surgery in class III patients by focusing on sella, nasion, A point (SNA) and sella, nasion, B point (SNB) angle and aesthetic outcome.

Materials And Methods: The sample consisted of 96 skeletal Class III patients (42 women, 54 men) with a mean age of 25 years with standard deviation (SD) of 8.4.

The short-term effects of face mask and fixed tongue appliance on maxillary deficiency in growing patients--a randomized clinical trial.

Background: The purpose of this single blind, prospective, parallel randomized trial study was to compare the effects of face mask and fixed tongue appliance in treatment of Class III malocclusion with maxillary deficiency in growing patients.

Methods: 88 patients with maxillary deficiency were selected. 60 fulfilled the study requirements.

Use of aesthetic rhinoplasty procedures in reconstructive nasal surgery.

Resection of cancer often involves the excision of underlying hard tissue, and some procedures in aesthetic rhinoplasty can be used in reconstructive nasal surgery to increase the margin of safety while still achieving an acceptable aesthetic and functional outcome. We have used techniques from aesthetic rhinoplasty to shape the nasal framework. Osteotomy and formation of the tip were used in 17 patients with defects (ranging from 1 to 3.

Noninvasive 3-dimensional evaluation of periorbital asymmetry in isolated unilateral orbital floor fractures.

Objective: The study was carried out to evaluate the degree of asymmetry between the injured and contralateral periorbital region in isolated orbital floor fractures after surgery.

Study Design: The periorbital asymmetry of 35 patients with medium-sized orbital floor fractures that were surgically treated with alloplastic resorbable implants was evaluated and compared with that of a healthy control group using an optical 3-dimensional facial scanner. Distance measurements between facial surface landmarks, as well as volume measurements between the original image and an automatically generated mirror image, were performed using commercially available software.

Soft-tissue changes associated with different surgical procedures for treating class III patients.

Objective: The aim of this study was to evaluate the effects of different surgical procedures on soft tissue and skeletal changes.

Patients And Methods: Pre- and postoperative lateral cephalograms of 191 class III patients aged 16-58 years were retrospectively analyzed and divided into three groups according to the surgical therapy they had undergone. Group I had undergone maxillary advancement (n=51), group II a bimaxillary (n=102) procedure, and group III mandibular setback (n=38).

The accuracy of computer-assisted primary mandibular reconstruction with vascularized bone flaps: iliac crest bone flap versus osteomyocutaneous fibula flap.

Background: The intention of mandibular reconstruction is to restore the complex anatomy with maximum possible functionality and high accuracy. The aim of this study was to evaluate the accuracy of computer-assisted surgery in primary mandibular reconstruction with an iliac crest bone flap compared with an osteomyocutaneous fibula flap.

Materials And Methods: Preoperative computed tomography data of the mandible and the iliac crest or fibula donor site were imported into a specific surgical planning software program.

Consideration of effect of the amount of mandibular setback on the submental region in the planning of orthodontic-orthognathic treatment.

Aesthetic outcome has gained in importance in the treatment of patients with orthognathic problems. Historically, Class III malocclusions have historically been treated by isolated mandibular setback and maxillary advancement, whereas bimaxillary procedures have recently become the more common option. Functional outcome and stability have been discussed previously.

Maxillary deficiency treatment by fixed tongue appliance--a case report.

This case illustrates orthopaedic treatment of a 12.1-year-old girl with class III malocclusion and maxillary deficiency. The patient was treated by a fixed tongue appliance in the upper jaw.

Bone remodeling to correct maxillary deficiency after growth cessation.

This case report presents a 22-year-old girl with class III malocclusion due to maxillary deficiency. The patient was referred for presurgical orthodontics; however, she rejected the surgery. This case was treated by means of Tongue appliance and slow palatal expansion, followed by lower fixed appliance, reverse chin cup, and upper fixed appliance.

The effects of facemask and reverse chin cup on maxillary deficient patients.

Introduction: The aim of this randomized clinical trial was to assess differences in the effects of face mask and reverse chin cup therapy on maxillary deficient growing patients.

Methods: The sample consisted of 42 class III patients with maxillary deficiency randomly divided into two equal groups. Twenty-one patients (10 males and 11 females) with a mean age of 8.

Functional long-term results after the harvest of vascularised iliac bone grafts bicortically with the anterior superior iliac spine included.

The aim of this study was to evaluate the postoperative morbidity at the donor site and the long-term outcome after the harvest of bicortical iliac bone grafts, including the iliac crest and the anterior superior iliac spine (ASIS), by using a confirmed score. We retrospectively examined 54 consecutive patients who had had vascularised iliac bone grafts harvested to reconstruct different parts of the mandible. We used the Harris Hip Score to evaluate objectively the long-term postoperative morbidity at the donor site.

Orthodontic treatment after autotransplantation.

Autotransplantation is an alternative method to replace a missing tooth. This study reports a 17-year-old man who had autotransplantation of the left upper third molar with the congenitally missing left lower second premolar. No signs of inflammation, root resorption, ankylosis, mobility, sensitivity, pocket problems, or pulp destructions were found after 2-year follow up.

Comparison of donor-site engraftment after harvesting vascularized and nonvascularized iliac bone grafts.

Purpose: The objective of this study is to characterize the donor-site morbidity after harvesting of nonvascularized and vascularized iliac bone grafts.

Patients And Methods: Clinical data of 353 patients were collected for analysis. In addition, a questionnaire was sent to all patients asking about their perceptions of different parameters.
