Surgical correction of nasal obstruction in the treatment of mild sleep apnoea: importance of cephalometry in predicting outcome.
BACKGROUND A study was undertaken to determine if cephalometric radiographs could identify those who will benefit from nasal surgery in patients with a sleep apnoea hypopnoea syndrome (SAHS) and chronic nasal obstruction. METHODS Fourteen patients with SAHS were enrolled. Those with normal posterior airway space and mandibular plane to hyoid bone distances on preoperative cephalometric radiog...
متن کاملPostural cephalometric analysis and nasal resistance in sleep-disordered breathing.
OBJECTIVES The study was designed to compare upright and supine cephalometric measurements in snorers and to evaluate the effects of mandibular position and nasal resistance on pharyngeal dimensions. Anthropometric, rhinomanometric, and cephalometric measurements were used to investigate predictors of apnea-hypopnea index. STUDY DESIGN Prospective, cross-sectional. METHODS Forty consecutive...
متن کاملSleep-disordered breathing in patients with acquired retrognathia secondary to rheumatoid arthritis.
BACKGROUND Sleep-disordered breathing (SDB) is associated with a variety of conditions that cause upper-airway narrowing. It was hypothesized that upper-airway narrowing can occur in patients with rheumatoid arthritis (RA) when retrognathia develops secondary to temporomandibular joint (TMJ) destruction. Therefore, the aim of this study was to detect the prevalence of SDB in patients with acqui...
متن کاملDiagnosis of sleep apnea by automatic analysis of nasal pressure and forced oscillation impedance.
Detecting and differentiating central and obstructive respiratory events is an important aspect of the diagnosis of sleep-related breathing disorders with respect to the choice of an appropriate treatment. The purpose of this study was to evaluate the performance of a new algorithm for automated detection and classification of apneas and hypopneas, compared with visual analysis of standard poly...
متن کاملHow does open-mouth breathing influence upper airway anatomy?
OBJECTIVES/HYPOTHESIS Open-mouth breathing during sleep may increase the severity of obstructive sleep apnea (OSA) and complicate nasal continuous positive airway pressure (CPAP) therapy in patients with OSA. The aim of this study was to assess the effect of open-mouth breathing on upper airway anatomy using lateral cephalometry and fiberoptic nasopharyngoscopy. STUDY DESIGN This was a cross-...
