BACKGROUND Failure to maintain a patent airway can result in brain damage or death. In patients with mandibular prognathism or retrognathism, intubation is generally thought to be difficult. We determined the degree of difficulty of airway management in patients with mandibular deformity using anatomic criteria to define and grade difficulty of endotracheal intubation with direct laryngoscopy. ...

Background and aims. One of the most common reasons forthe inferior alveolar nerve block anesthesia failure is the variation in mandibular foramen location. The aim of this study was to assess the location of mandibular foramen in children with mandibular retrognathism in comparison to children with normal skeletal occlusion in the mixed dentition. Materials and methods. One hundred and twenty ...

We report a case involving a young female patient with severe mandibular retrognathism accompanied by mandibular condylar deformity that was effectively treated with Le Fort I osteotomy and two genioplasty procedures. At 9 years and 9 months of age, she was diagnosed with Angle Class III malocclusion, a skeletal Class II jaw relationship, an anterior crossbite, congenital absence of some teeth,...

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. ...

Class II malocclusion is one of the most commonly occurring conditions, and component mostly involved mandibular retrognathism. The treatment modalities include both removable fixed appliances. advantage functional appliances that it not dependent on patient compliance. Various are available such as rigid, flexible, hybrid. present case series discusses a hybrid type appliance, i.e. Twin Force ...

The aim of this study was to assess the relationship between cranial base, mandible, and hyoid bone in Class II skeletal individuals. retrospective included lateral cephalograms 40 Skeletal subjects divided into maxillary prognathism (n=20) mandibular retrognathism(n=20) based on Burstone’s N⊥A N⊥B values. angular measurements using 10 variables were used determine subjects. Statistical analyse...

Abstract Introduction: Estimating the appropriate time for orthodontic treatment is a crucial factor. Given the earlier maturation of sinuses rather than maxillomandibular growth, finding the exact relationship between the growth of the jaws and frontal sinuses is considered to be a helpful element in Orthodontic treatment. Materials and Methods: This is a descriptive-analytical study, conduc...
