Complete Toenail Removal During Toenail Resection
Yes, the entire toenail can be removed during a toenail resection, and this approach is well-established for specific clinical indications, though partial nail removal with matricectomy is generally preferred for most conditions to preserve cosmetic appearance.
When Complete Nail Removal Is Indicated
Complete nail plate avulsion is appropriate in several clinical scenarios:
Severe onychomycosis with dermatophytoma: When dense fungal lesions (dermatophytomas) are present beneath the nail plate, mechanical removal of the entire nail may be necessary to access and eliminate the infection, as these lesions can be resistant to antifungal treatment without prior removal 1.
Onychogryphosis (grossly thickened nails): The matrix of the entire nail can be removed to eliminate problems associated with severely deformed, thickened nails 2.
Chronic or recurrent nail infections: When there is persistent infection with nail abnormalities that have failed conservative treatment 2.
Surgical Approaches and Outcomes
Complete Nail Avulsion Techniques
Complete nail plate removal can be performed with or without matricectomy (destruction of the nail root):
Simple avulsion alone: Removal of the nail plate without matrix destruction allows for nail regrowth but may not address underlying pathology 3.
Avulsion with matricectomy: Combining complete nail removal with matrix destruction prevents regrowth and is definitive for chronic conditions 2, 3.
Comparative Effectiveness
Research comparing surgical approaches shows:
Wedge resection plus complete nail plate avulsion versus wedge resection alone (Winograd procedure) demonstrated similar outcomes: surgical duration (
15 minutes), healing time (2.7-2.8 weeks), low recurrence rates (3-4%), and minimal infection rates (2-3%) 4.Cosmetic considerations favor partial procedures: When the nail plate remains intact (as in wedge resection alone), cosmetic results are superior, making this the preferred choice when clinically appropriate 4.
Complete avulsion with wedge excision of nail fold achieved high cure rates (95% success) with short postoperative pain duration and low infection risk, while also providing good aesthetic results 5.
Clinical Caveats and Pitfalls
Avoid complete nail removal as first-line treatment for onychomycosis: Surgical avulsion followed by topical antifungal therapy showed disappointing results in randomized controlled trials and is not recommended based on current evidence 1.
Debridement alone is insufficient: Mechanical intervention without addressing the underlying pathology (such as matrix destruction or antifungal therapy) cannot be recommended as definitive treatment 1.
Risks of complete nail removal include 3:
- Infection
- Chronic ulcer formation
- Prolonged healing
- Irregular nail regrowth (if matrix not completely destroyed)
- Recurrence
- Pain
Practical Surgical Considerations
The technical approach for complete nail removal:
Anesthesia: Digital nerve block of the toe is required for extensive procedures 2.
Sharp dissection preferred: When removing the matrix, sharp dissection is relatively easy and more dependable than other methods of matrix destruction 2.
Healing time: Patients typically return to daily activities in 3 days with mean healing time of 10 days 6.
Minimal matricectomy approach: Creating a 2-mm space between tissue and nail with only minimal matricectomy provides excellent results (1.7% recurrence rate) while preserving function and aesthetics 6.
