What are the methods to minimise bleeding during rhinoplasty?

Methods to Minimise Bleeding in Rhinoplasty

To minimise bleeding during rhinoplasty, preoperative oral tranexamic acid (1g given 2 hours before surgery) should be administered, combined with intraoperative controlled hypotension, head elevation, and meticulous surgical technique that avoids unnecessary periosteal elevation.

Preoperative Pharmacological Interventions

Tranexamic Acid (Primary Recommendation)

• Oral tranexamic acid 1g (2 × 500mg tablets) administered 2 hours preoperatively significantly reduces intraoperative blood loss by approximately 55mL compared to placebo 1, 2
• This intervention decreases mean blood loss from 199.6mL to 144.6mL and improves surgical field visualization 2
• Tranexamic acid also reduces postoperative eyelid edema (WMD -0.76) and periorbital ecchymosis (WMD -0.94) within the first postoperative week 1
• No thromboembolic events have been reported with preoperative tranexamic acid use in rhinoplasty patients 1
• Oral administration appears more effective than intravenous (WMD -61.70mL vs -23.88mL reduction) 1

Corticosteroids

• Perioperative corticosteroids demonstrate consensus effectiveness in reducing both intraoperative bleeding and postoperative edema/ecchymosis 3
• These should be administered as part of the standard protocol for bleeding minimization 3

Anticoagulation Management

• Discontinue aspirin, ibuprofen, and other antiplatelet/anticoagulant medications preoperatively 4
• Acetaminophen does not increase bleeding risk and can be used for pain management 4
• Coordination with cardiology or hematology may be necessary for patients requiring anticoagulation for medical conditions 4
• Risk stratification tools like HAS-BLED score should guide decision-making for high-risk patients 4

Intraoperative Techniques

Controlled Hypotension

• Intraoperative controlled hypotension is strongly supported by consensus evidence to reduce bleeding 3
• This technique significantly decreases blood loss and improves surgical field quality 3

Intraoperative Cooling

• Application of cold during surgery reduces intraoperative bleeding and subsequent postoperative edema 3
• This represents a low-risk intervention with demonstrated benefit 3

Surgical Technique Modifications

• Avoid unnecessary periosteal elevation before osteotomy, as this increases bleeding and postoperative morbidity 3
• Minimize nasal packing use, as packing increases postoperative edema and ecchymosis 3
• Use meticulous hemostatic technique with mono-/bipolar cautery and vascular clips when needed 4
• Consider transcervical ligation of external carotid artery branches for high-risk cases 4

Topical Vasoconstrictors

• Apply topical vasoconstrictors (oxymetazoline or phenylephrine) to the nasal mucosa intraoperatively 4, 5
• These agents resolve 65-75% of mucosal bleeding when applied appropriately 5

Postoperative Management

Head Elevation

• Maintain head elevation postoperatively to minimize venous congestion and bleeding 3
• This intervention has strong consensus support for reducing edema and ecchymosis 3

Compression and Monitoring

• Apply firm sustained compression if postoperative bleeding occurs 5
• Cold packs should be applied to reduce periorbital edema and ecchymosis 6

Avoidance of Bleeding Triggers

• Patients must avoid forceful nose blowing, nasal picking, and strenuous activity for 24 hours postoperatively 5
• Continue avoiding aspirin and NSAIDs in the immediate postoperative period 4

Patient Risk Stratification

High-Risk Factors Requiring Special Attention

• Previous nasal or sinus surgery increases technical difficulty and bleeding risk 4, 7
• Uncontrolled hypertension must be managed perioperatively in collaboration with medical specialists 4
• Hereditary or acquired coagulopathies require hematology consultation 4
• Chronic kidney or liver disease increases bleeding risk 4
• Smoking increases wound complications and should prompt cessation counseling 7

When Standard Measures Are Insufficient

• For persistent bleeding uncontrolled by standard measures, consider surgical arterial ligation or endovascular embolization 4
• These interventions should be evaluated or referred promptly rather than continuing ineffective conservative management 4

Common Pitfalls to Avoid

• Do not routinely use nasal packing, as it increases postoperative morbidity without clear benefit in most cases 3
• Avoid excessive periosteal elevation, which significantly increases bleeding 3
• Do not delay tranexamic acid administration—it must be given 2 hours preoperatively for optimal effect 2
• Avoid inadequate preoperative assessment of anticoagulation status, which can lead to life-threatening hemorrhage 4
• Do not attempt to rapidly lower blood pressure in hypertensive patients, as this may cause end-organ ischemia without proven benefit for epistaxis control 4
