Genioplasty for genioglossus muscle advancement in patients with obstructive sleep apnea-hypopnea syndrome and mandibular retrognathia.
(25/60)
Obstructive sleep apnea syndrome is a complex disease, which the etiology is multifactorial and incompletely understood. Surgery with genioglossus advancement is indicated in hypopharynx obstruction. AIM: evaluate the efficacy and complications of genioplasty technique for genioglossus muscle advancement in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). METHODS: polysomnography, physical examination and cephalometric analysis were performed in 10 non-obese patients, who presented mild or moderate OSAHS, an apnea-hypopnea index (AHI) between 5 and 30, with hypopharynx obstruction and mandibular retrognathia. RESULTS: the AHI preoperative mean of 12.4+/-4.6 decreased to a postoperative mean of 4.4+/-5.7 (p < 0,001). When 50% reduction of preoperative AHI was chosen as a parameter, its rate was 70% (7/10). Cephalometric analysis revealed an increase in the posterior airway space (PAS) in all patients, from a preoperative mean value of 7.9+/-2.3mm to a postoperative mean value of 10.8+/-2.5mm (p < 0,001). CONCLUSION: genioplasty for genioglossus advancement seemed to reduce OSAHS signs, thus, it can be considered as an option for the surgical treatment of patients with hypopharynx obstruction. Data collected supports this surgical procedure as an option in patients with OSAHS and mandibular retrognathia. (+info)
Juvenile idiopathic arthritis: a chronic pediatric musculoskeletal condition with significant orofacial manifestations.
(26/60)
Juvenile idiopathic arthritis (JIA), a broad term that describes a clinically heterogeneous group of arthritides of unknown cause, begins before 16 years of age. The hallmark feature of JIA is chronic inflammation of the joints, but the term encompasses several disease categories. The cause of JIA is still poorly understood and none of the available drugs for JIA can cure the disease. However, the prognosis has greatly improved as a result of progress in disease classification and management. The dental practitioner should be familiar with the symptoms and oral manifestations of JIA to help manage this disease. (+info)
Clinical application of curvilinear distraction osteogenesis for correction of mandibular deformities.

Recessive dystrophic epidermolysis bullosa (Hallopeau-Siemens type) (RDEB-HS) is a rare severe mechanobullous disorder resulting from a defect in collagen VII. Patients with RDEB-HS present with generalized blistering and denudation of the skin at birth and have mucosal involvement. The repeated blistering leads to scarring, which may be deforming and result in serious complications. Transmission electron microscopy is currently the gold standard for diagnosis of RDEB-HS.
