“…All subjects underwent a physical examination of the oropharynx with the palatine tonsils classified according to Mackenzie. The lateral pharyngeal folds and the tongue level were rated on a three‐point scale (Fujiwara et al ., 1993). The research subjects had no previous peritonsillitis.…”

An elderly man with acute anterior wall myocardial infarction who underwent medical therapy followed by angioplasty and stenting was referred to our centre for evaluation of sleep-disordered breathing. The gentleman had moderate hypothyroidism for which he was on replacement therapy. At our centre PSG showed OSA for which a trial of CPAP was given. On correction of OSA by CPAP, presence of underlying CSA was unmasked. The patient improved over time on intensified medical therapy, continuous use of CPAP and regulated thyroid replacement therapy.

This study compared the tissue tone of the soft palate in nonsnoring subjects and patients with obstructive sleep apnoea syndrome (OSAS) during wakefulness. Here, tissue tone means the biomechanical property of the tissue which can be characterized by two main parameters: stiffness and elasticity. Tissue tone includes both structural and neural components. A new method to evaluate the tissue tone of the soft palate was used - computerized endopharyngeal myotonometry (CEM). This method records and analyses the response of the soft palate tissues to a brief mechanical impact. The method enabled us to evaluate the most important parameters of tissue tone: stiffness, which is expressed as a frequency; and elasticity, expressed as a logarithmic decrement of the damped oscillation. First, a self-reported questionnaire was completed about the medical history of the subjects. Subjects then underwent a physical examination of the oropharynx and polysomnography with overnight pulse oximetry. The results of the CEM method indicated that patients with OSAS show an increased stiffness of the soft palate tissues (20.3, SD 4.7 Hz) compared with nonsnoring subjects (12.2, SD 1.8 Hz). In patients with sleep apnoea, elasticity is not increased in a similar way to stiffness. Thus, the disproportion between tissue stiffness and elasticity of the soft palate is a measure of the pathological changes in patients with sleep apnoea.
