Systematic head and neck physical examination as a predictor of obstructive sleep apnea in class III obese patients.

چکیده
Our aim was to determine if anatomical abnormalities of the upper airway (UA) and facial skeleton of class III severely obese patients are related to the presence and severity of obstructive sleep apnea syndrome (OSAS). Forty-five patients (69% females, mean age 46.5 +/- 10.8 years) with a body mass index (BMI) over 40 kg/m(2) underwent UA and facial skeletal examinations as well as polysomnography. Mean BMI was 49 +/- 7 kg/m(2) and mean neck circumference was 43.4 +/- 5.1 cm. Polysomnographic findings showed that 22% had a normal apnea-hypopnea index (AHI) and 78% had an AHI over 5. The presence of OSAS was associated with younger age (P = 0.02), larger neck circumference (P = 0.004), presence of a voluminous lateral wall (P = 0.0002), posteriorized soft palate (P = 0.0053), thick soft palate (P = 0.0014), long uvula (P = 0.04), thick uvula (P = 0.0052), and inferior turbinate hypertrophy (P = 0.04). A larger neck circumference (P = 0.02), presence of a voluminous lateral wall (P = 0.04), posteriorized soft palate (P = 0.03), and thick soft palate (P = 0.04) were all associated with OSAS severity. The prevalence of OSAS in this group was high. A larger neck circumference and soft tissue abnormalities of the UA were markers for both the presence and severity of OSAS. Conversely, no abnormalities in the facial skeleton were associated with OSAS in patients with morbid obesity.

BACKGROUND The parapharyngeal space (PPS) is a rare site for neoplasms in the head and neck and lipoma represents 0.5% of all head and neck tumors. CASE REPORT We describe a case of a giant parapharyngeal lipoma in obese adult patient causing anatomic pharyngeal obstruction with severe obstructive sleep apnea (OSA) syndrome. The patient was successfully operated with transcervical approach. ...

Morbid obesity is associated with a more rapid decrease in oxygen saturation during apnea following induction of anesthesia, compared to patients who have normal weight1. This is particularly hazardous as morbid obesity, complicated by obstructive sleep apnea, may be associated with an increased risk of difficult tracheal intubation and difficult face mask ventilation2. These morbidly obese pat...
