Management of Postoperative Oral Purpuras and Bleeding: An Insight

How Can Oral Purpuras and Bleeding Be Caused Postoperatively After a Dental Procedure in High-Risk Cases?

Purpura, also commonly known as bleeding blood spots, or skin hemorrhages, refers to purple-colored spots that manifest in the oral cavity, especially after post-operative dental or oral surgical procedures. These post-operative discoloration spots would be recognizable by the dentist even on routine dental examination as a result of oral injuries or trauma commonly, or post-operatively in situations like when an oral surgery or extraction is performed when a dental implant is placed. The purpura spots would even appear on the oral mucous membranes, periorally, on the lips, or any membranes on the inside of the mouth. Purpura occurs usually when the small blood vessels are afflicted by either trauma, injury, or surgical-induced trauma, which would cause the vessels to burst, causing blood to eventually pool beneath the oral mucosa, mucous membranes, or the epidermis of the skin.

Before any dental surgical treatment, it is important to always elicit the medical history of the patient. It is important to know and assess the dosage of any systemic medications that would be taken by the patient before the dental or oral surgical appointment. The incidence of cardiovascular diseases globally has led to strict protocols or clinical management guidelines that should be followed by the dentist or maxillofacial surgeon in such high-risk cases.

Would Oral Purpuras Require Emergency Management in a Dental Clinic?

Individuals on oral anticoagulant therapies or anti-thrombotic agents who are easily prone to developing thromboembolic events very often, even despite good surgical management in the dental setting, can still develop the common oral purpuras as a result of the surgically induced trauma that would cause the blood pooling under the site affected, the oral mucous membranes, or the gingival tissues. Though purpuras themselves may not require any emergency management, they can still be a cause of local oral bleeding. This necessitates that in the hospital setting, the dentist or the maxillofacial surgeon should take adequate precautions to control the bleeding effectively or achieve hemostasis. Minor bleeding complications after oral surgical procedures usually in high-risk patients, can initiate thromboembolic events. Hence, any necessary surgical modifications should be performed by the dentist or surgeon, including temporary dental procedures for high-risk cases such as patients with bleeding disorders, cardiovascular diseases, those on anticoagulant therapy, and immunocompromised patients.

How Should Bleeding and Purpura Be Managed Surgically in Oral Surgery and Implant Dentistry?

The dentist would usually require interdisciplinary collaboration with the physician before performing the oral surgical or implant-based procedure. For instance, most physicians usually advise that a temporary discontinuity in the oral anticoagulants can be beneficial in treating patients on the commonly prescribed vitamin K antagonists or anticoagulant-based therapies, who would be prone to developing post-operative purpuras.

Current dental research and guidelines for surgeons suggest that in specific cases of extensive oral surgeries such as dental implantation, dentoalveolar surgeries can be quite safely performed as long as the dental setting is patient compliant, for a short duration preferably in the morning hours (for better oral motor control) and with local hemostatic measures in the dental clinic or hospital in place to manage the patients bleeding risks. For instance, even on patients with anticoagulant therapies, an implant dentist can place as many as two to three implants in a short dental sitting with the feasibility of ensuring proper local hemostatic measures are in place and with the consent and instructions of the general physician, who will advise accordingly on what dosage of the anticoagulant should be taken on the day of the dental appointment or whether it can be skipped totally on the dental appointment day in question.

The concept of atraumatic extractions and immediate dental implant placement is one of the highly effective procedures in modern-day implant dentistry to control the risks of post-operative bleeding and oral purpuras.

Can Individuals With Pre-existing Oral Diseases or Periodontal Disease Show More Purpuras After Surgery?

According to dental experts and researchers, pre-existing oral disease patterns or their progression can happen in advanced stages of gingival and periodontal diseases, in tooth mobility, in inflamed oral mucosal membranes, the presence of granulation tissue in several oral infections, in orofacial or facial space infections, in oral infections caused by bacterial, viral, or fungal origin. In all these cases as well, the presence of bleeding with increased occurrence of purpuras can be seen as per medical case reports.

What Are the Management Aspects for Controlling Bleeding and Purpuras Postoperatively in High-Risk Patients?

Postoperatively, after an oral surgical procedure, the dentist must check whether local hemostatic pressure using the gauze method is required to effectively clot the blood at the surgical site or the implanted area in high-risk patients. Further, when local pressure does not work in controlling blood loss, then the use of oxidized cellulose, bone wax, and styptic agents can be considered. Resorbable or non-resorbable sutures are also a good option to control bleeding and purpuras at the surgical site. In patients who are on anti-coagulation therapies, physicians can manage these dental cases by prescribing them Rivaroxaban therapy, which has been introduced as an alternative to Warfarin therapy. Rivaroxaban is a new-age drug that can overcome some limitations with Warfarin therapy, such as it does not require coagulation monitoring, has a rapid onset of action, and has limited drug interactions with dental antibiotics or with painkiller medications according to preliminary medical and dental research. Rivaroxaban therapy can hence be initiated in high-risk cases as per the physician's advice.

As for the dental precautions, flap approximation, closure of surgical margins, and if the purpuras are still seen, achieving hemostasis through sterile tranexamic acid-soaked gauze for eight to 10 minutes duration can be effective in post-operative bleeding control.

Conclusion:

According to current dental research and guidelines or protocols to be followed in maxillofacial surgery, dentists must understand the patient compliance factors, assessing their local and systemic health conditions that represent a crucial part of the evaluation process for postoperative bleeding and purpuras. Furthermore, bleeding and oral purpuras are extremely common in high-risk groups such as children, pregnant individuals, the elderly, and immunocompromised populations.
