The increased gonial angle in micrognathism

American Journal of Orthodontics, 1953
Abstract 1. 1. The normal mandible has an angle of about 125 degrees between the ramus and the body. 2. 2. Many cases of moderate micrognathism show this angle to be increased as much as 150 degrees. Associated with this increase is a constant esthetic deformity of an excessive superior-inferior length giving the appearance of a “lantern jaw.”

Micrognathism corrected by vertical osteotomies of the rami without bone grafts

Oral Surgery, Oral Medicine, and Oral Pathology, 1962
Abstract A modified procedure for correction of micrognathism by bilateral vertical osteotomies of the mandibular rami without bone grafts has been used in fourteen patients. An abbreviated case report has been presented to illustrate the technique.

Mandibular Distraction in Glossoptosis-Micrognathic Association

Journal of Craniofacial Surgery, 1998
Surgical treatment for glossoptosis-micrognathic association is indicated in the most severe cases. Usually, complications occur. We used mandibular distraction to pull the tongue away from the posterior pharyngeal wall. This procedure, used in 3 patients, was effective.

Predicting Surgical Intervention for Airway Obstruction in Micrognathic Infants

Otolaryngology–Head and Neck Surgery, 2013

Assessment of pharyngeal airway stability in normal and micrognathic infants

Journal of Applied Physiology, 1985
A current hypothesis for obstructive sleep apnea states that 1) negative airway pressure during inspiration can collapse the pharyngeal airway, and 2) neural control of pharyngeal airway-dilating muscles is important in preventing this collapse. To test this hypothesis we performed nasal mask occlusions to increase negative pharyngeal airway pressures

Control of respiratory activity of the genioglossus muscle in micrognathic infants

Journal of Applied Physiology, 1986
The genioglossus (GG) muscle activity of four infants with micrognathia and obstructive sleep apnea was recorded to assess the role of this tongue muscle in upper airway maintenance. Respiratory air flow, esophageal pressure, and intramuscular GG electromyograms (EMG) were recorded during wakefulness and sleep. Both tonic and phasic inspiratory GG-EMG

Mandibular skeletal dysmorphology in micrognathic mice.

Progress in clinical and biological research, 1985
The primary manifestations of micrognathia were microglossia, midline fusion of the right and left sides of the mandible, total absence of incisor and molar toothbuds and, in many cases, absence or perhaps premature resorption of Meckel's cartilage. In addition, there was altered osteogenesis as evidenced by disrupted trabecular patterns, as well as an
