3、Nasopharyngeal airway tubes were inserted as a stent in those who underwent lateral rhinotomy to keep airway open.
2、Purpose: This retrospective study evaluated the change in pharyngeal airway space associated with surgical mandibular setback.
4、Conclusion Sputum drainage through oropharyngeal airway is more effective than through nasal cavity directly, and it will not affect oxygen therapy during its process.
1、Correlation between the craniofacial morphology, pharyngeal airway and the head posture;
