“…Active acromegalic patients have increased tongue volumes by MRI (18). Additionally, when compared with non-obstructive SA controls, patients with OSA had a higher length and area of soft palate; tongues that were not only more inferiorly positioned but also had more tongue tissue at the hypopharyngeal level; and pharyngeal airway spaces that had significantly reduced anteroposterior dimensions at the nasopharyngeal, oropharyngeal, and hypopharyngeal levels (24). Of all the cephalometric parameters evaluated, the sole with a well-characterized reference value is soft palate (15) that proved to be enlarged in 63.1% of patients (12/19).…”

Objectives: To determine the prevalence of sleep apnea (SA) and SA syndrome (SAS) in patients with acromegaly and correlate SA with clinical, laboratory, and cephalometric parameters. Design and methods: Prospective and cross-sectional study of 24 patients with active acromegaly evaluated by clinical and laboratory (GH, IGF-I) parameters, polysomnography and magnetic resonance imaging (MRI) of the pharynx. Results: Out of 24 patients, 21 had SA (87.5%), of which 20 (95.3%) had the predominant obstructive type. Median age of these 21 patients was 54 years (range 23-75) and median estimated disease duration was 60 months (range 24-300). The frequency in SA patients of impaired glucose tolerance, diabetes mellitus (DM), and hypertension was 19, 33.3, and 71.4% respectively. Goiter was found in 10 patients (47.6%) and obesity in 18 (90%). Median GH level was 14 mg/l (1.4-198) and median %IGF-I (percentage above the upper limit of normal range of IGF-I) was 181% (K31.6 to 571.2). The prevalence of SAS was 52.4%. Apnea-hypopnea index (AHI) correlated significantly with age, waist circumference, body mass index, and hypopharynx area. The AHI was significantly higher in patients with hypertension and DM. Conclusions: The prevalence of SA and SAS in acromegaly was similar to the one previously described in other series. Age was a significant risk factor, and hypertension and DM were significantly associated complications of SA. Obesity was also significantly related to SA, as a risk factor, a complication or both. Overall, cephalometric parameters by MRI did not correlate with SA.European Journal of Endocrinology 158 459-465
