Abstract
• The impact of nasotracheal and orotracheal long-term intubation on the development of sinusitis paranasalis was investigated in a prospective study. Daily A-scan ultrasound examinations of the maxillary sinuses were performed on 44 intensive care unit patients (20 nasally, 24 orally intubated) who required prolonged intubation (>24 hours). At the end of the investigation period 19 (95%) of 20 nasotracheally and 15 (63%) of 24 orotracheally intubated patients showed pathologic antral sinus findings. In nasally intubated patients the incidence of bilateral sinusitis was significantly higher and its onset sooner. Pathologic organisms were found in the sinus aspirates in seven of 13 nasotracheally intubated patients, but only in two of nine patients with an oral tube. Thus, the nasotracheal tube can be seen as an adding factor in the development of sinusitis paranasalis.
