OBJECTIVE The aim of this study is to compare patients treated with pharyngoplasty and those treated with palatoplasty for velopharyngeal insufficiency to establish what surgical procedure poses the highest risk for developing sleep apnea. The hypothesis tested in this study is that the incidence of obstructive sleep apnea syndrome associated with pharyngoplasty is greater than that associated ...

OBJECTIVES To examine sleep disordered breathing including obstructive sleep apnoea in patients with idiopathic adult hydrocephalus syndrome (IAHS) and to study the effects of CSF drainage and shunting procedure on sleep disordered breathing. METHODS In 17 patients with IAHS polysomnographic investigations were performed before and after lumbar CSF drainage and after shunt operation. RESULT...

The objective of this study was to assess whether an increasing severity of sleep apnoea is associated with increased all-cause mortality hazards and to assess whether the syndrome is associated with excess mortality, in comparison with the general population. Participants included 14,589 adult males, aged 20-93 yrs, referred to the sleep clinics with suspected sleep apnoea or diagnosed with sl...

OBJECTIVES/HYPOTHESIS To determine if supraglottoplasty (SGP) is effective in reversing abnormal respiratory parameters in children with laryngomalacia and obstructive sleep apnea (OSA). STUDY DESIGN Retrospective case series at a tertiary referral children's hospital. METHODS Ten patients with laryngomalacia and OSA as documented by polysomnography underwent SGP between 2005 and 2007. Data...

Sleep apnoea syndrome (SAS) is common in acromegalic patients. Occasionally, the relief of apnoeas after treatment of the acromegaly has been documented. We report the cases of three patients with acromegaly and severe obstructive sleep apnoea, who demonstrated a manifest improvement (respiratory disturbance index (RDI) <20) after treatment with octreotide, indicating that this drug may be effe...

Although chronic sleep fragmentation and oxygen saturation (Sao2) drops alone do not induce obstructive sleep apnoea (OSA), both are part of the feedback loop leading to obstructive sleep apnoea syndrome (OSAS). To determine factors in respiratory disturbance and Sao2 drops, we used polysomnographic and cephalometric data from 120 OSAS patients to construct a model which we then applied prospec...
