Endoscopic transaxillary approach for congenital muscular torticollis.

Abstract

BACKGROUND:

Surgical correction of the congenital muscular torticollis (CMT) is recommended for patients with unsuccessful conservative treatment. Open operative techniques all leave noticeable scars. We proposed a modified endoscopic 1-trocar transaxillary and neck microincision approach for the treatment of CMT.

METHODS:

Endoscopic release of the sternocleidomastoid (SCM) muscle was performed in 45 infants and children aged 6 months to 15 years. One 5-mm incision was made in the anterior axillary fold, and a subcutaneous tunnel over the clavicular and sternal heads of the SCM muscle was made. A subcutaneous space was established by CO₂ inflation at a pressure of 8 mm Hg and then endoscopically using a 5-mm endoscope. Two additional 1.5- to 2-mm supraclavicular mini-incisions were made beside the SCM muscle for the introduction of miniforceps and electrocautery, respectively. The sternal and clavicular attachments were dissected and divided by electrocautery. Clinical evaluation was performed using the Lee scoring system.

RESULTS:

The operation was successfully completed endoscopically in all 45 children. The mean operative time was 40 minutes. No injuries of major blood vessels or nerves were encountered. A small bleed was noted in 1 child owing to reoperation. Follow-up for 6 months to 3 years in 42 patients showed complete muscular release and satisfactory cosmetic appearance with no recurrence. The results were classified as excellent in 88.1% (37/42), good in 9.5% (4/42), fair in 2.4% (1/42), and poor in 0 using the Lee scoring system. The neck scars were not visible 1 month after the procedure.

CONCLUSIONS:

The subcutaneous endoscopic transaxillary and micro-neck incision approach for the treatment of CMT is a safe, practical procedure that provides good functional and cosmetic outcomes without vascular or neural injury.
