ABSTRACT
Objective To analyze the application of multi‐slice spiral CT and 3D airway reconstruction technique on obstruc‐tive sleep apnea syndrome (OSAS) of pharyngeal soft tissue and upper airway stenosis .Methods Selected 92 patients with OSAS in our hospital as the observation group and another 92 healthy persons were selected as control group ,all patients achieved multi‐slice CT and 3D airway reconstruction technical inspections ,counted and compared their pharyngeal soft tissue and upper airway stenosis .Results Airway stenosis of tongue back ,and hypopharynx retro‐palatal of control group were more narrow compared with the control group(P<0 .05);the observation group′s pharyngeal soft tissue was more thick than the control group ,so as the length and width(P< 0 .05) .Conclusion Multi‐slice spiral CT and 3D airway reconstruction technique can effectively share pharyngeal soft tissue and upper airway stenosis of patients with OSAS .
