Clinician Specialty: Podiatrist
Procedure
Partial Nail Avulsion with Phenol Matricectomy
Indication
Chronic, recurrent ingrown toenail (onychocryptosis) of the left hallux, resistant to conservative treatment and causing significant pain and recurrent infection.
Preoperative Assessment
Patient is a 32-year-old male with no significant medical history. No known drug allergies. Medications: None. Physical examination revealed hypertrophy of the lateral nail fold of the left great toe, with granulation tissue and purulent discharge. No signs of cellulitis extending beyond the digit. Peripheral pulses palpable, capillary refill time normal. No neurological deficits noted.
Anaesthesia
Local anaesthesia using 2% Lidocaine with Adrenaline (1:80,000).
Batch number: LA20241015A, Expiry date: 2026-03-15.
Procedure Details
The toe was prepared with antiseptic solution and draped. A digital tourniquet was applied to the base of the left hallux. A Freer elevator was used to gently separate the lateral aspect of the nail plate from the nail bed. A straight nail splitter was then used to make an incision approximately 3mm from the lateral nail edge, extending proximally to the eponychium. The nail segment was grasped with a haemostat and avulsed with a rotational motion. Haemostasis was achieved. A small cotton bud saturated with 88% Phenol was applied to the exposed nail matrix for 60 seconds, repeated three times, ensuring thorough contact with the germinal matrix. The area was then flushed with isopropyl alcohol to neutralise the phenol. The nail sulcus was cleared of any debris. A non-adherent dressing was applied.
