Five years experience of coniotomy.

The view held over the last six decades that coniotomy often leads to subglottic stenosis has recently been called into question. In this study 203 electively performed coniotomies were analysed. The operation was found to be much simpler than tracheostomy. No severe intra- or postoperative complications occurred. Six months after decannulation 61 patients operated on were alive and accessible to follow-up examination. No evidence of subglottic stenosis was found. The main disadvantage was a relatively high frequency of voice disorder.

[Elective coniotomy. Experiences with 103 personal cases].

The view held for the last 60 years that coniotomy often leads to subglottic stenosis has recently been called into question. In the present study 103 elective coniotomies are analysed. The operation was much easier than tracheotomy, and there were no severe complications during or after operation. Six months after decannulation 31 patients were alive and 28 available for follow-up examination. No evidence of subglottic stenosis was found. The main disadvantage of this operation would seem to be a tendency for the development of voice changes.

Elective coniotomy. A prospective study.

The view current over the last 60 years or so that coniotomy often leads to subglottic stenosis has recently been called into question. In the present study 103 electively performed coniotomies have been analysed. The operation was found to be much easier than tracheotomy. There was no case of severe peroperative or postoperative complications. Six months after decannulation 28 patients were alive and accessible to follow-up examination. No evidence of subglottic stenosis was found. The main disadvantage of this operation would seem to be a tendency for the development of voice changes.

Blood flow in the rabbit maxillary sinus mucosa. Measurement with a diffusible and a non-diffusible tracer.

The blood flow of the sinus mucosa was studied in 11 New Zealand White rabbits. Their body weight averaged 3.5 kg. The blood flow determinations were performed during neurolept anaesthesia with continuous blood pressure recording. The blood flow in the sinus mucosa and septum, as well as in other organs, was determined both with Sn113-labelled microspheres and with Rb86Cl. Cardiac output as determined with the microsphere method was 146 +/- 36 ml X min-1 X 1000 g-1 body weight. There was a good correlation between the blood flow values obtained with the two methods. The blood flow in the sinus mucosa was 0.58 +/- 0.41 ml X min-1 X g-1 when measured with microspheres and 0.43 +/- 0.34 ml X min-1 X g-1 with the Rb86Cl technique. In the septal mucosa the corresponding values were 0.42 +/- 0.20 ml X min-1 X g-1 and 0.49 +/- 0.43 ml X min-1 X g-1 respectively.
