Al,
Sorry to here about the sequence of events you describe. Without actually examining you I cannot be sure what is going on. However, let me try to make some sense out of this whole surgical bleeding issue.
Think about an infected cyst as a balloon filled with water the walls of the cyst were more or less attached to the surrounding skin and underlying muscle. With infection these attachments swell up and lead to the scarring that makes a secondary removal technically more difficult. When one incises the cyst and evacuates the liquid pus contents, then a hole is left behind. Your surgeon did not likely remove any tissue since the cyst itself is only the wall of the balloon. The cyst is normally filled with a mixture of cheesy dead skin and skin oils. However, this hole is not like a hole make by digging out some material, it is a hole that was made by expansion of the cyst pushing the surrounding tissues away. When all is healed this will come together without a noticeable defect.
In regards to the bleeding, infected tissue is friable and has in growth of blood vessels to bring the white blood cells to the infection. These are tiny vessels and usually stop by pressure dressing or packing the cavity with some sort of gauze drain. During the early stages, removal of the dressing or the drain allows these vessels to bleed since any clot at the bleeding end is easily disrupted. Alas, the Coumadin does no help and will prolong the time course of bleeding and healing.
As far as the volume of blood loss, there are some interesting behavior patterns of patients regarding the site of the bleeding in the perception of the severity of the problem. Several tablespoons from the nose or anywhere on the face makes most patients feel that they are going to die. On the other hand, vomiting up large quantities of blood or passing the same by rectum seems to be underestimated as to the severity. If I may reveal some of my male chauvinist tendencies, women who have the experience of menstruating frequently under or over estimate the volume of blood loss from any of these same areas.
Bottom line, if your dressing is not leaking through between dressing changes, then you are having not significant blood loss.
I will be out of reach for the next several days because of entering the hospital for a second try at ablation for AF.
P.S. Most nosebleeds and ear canal lacerations are from self inflicted reasons. Sometimes trying to convince a paretn to cut their childs nails is a challenge since they didn't come to a doctor, pay high fees, and be told that they need to more carefully groom their child. now adults, that is another story completely
