Recurrent laryngeal nerve injury: an experience with 310 thyroidectomies

Area of Science:

• Surgical outcomes
• Endocrine surgery

Background:

• Thyroid surgery carries risks, including nerve injury, although mortality is low.
• Morbidity from thyroid surgery, particularly nerve damage, remains a significant concern.

Purpose of the Study:

• To determine the prevalence of recurrent laryngeal nerve (RLN) injury during thyroid surgery.
• To assess the duration of recovery following transient recurrent laryngeal nerve injury.

Main Methods:

• Prospective, observational study conducted from January 2000 to December 2005.
• Inclusion of all patients undergoing thyroid surgery at Fauji Foundation Hospital, Rawalpindi.

Main Results:

• 3.22% of 310 thyroid surgery patients experienced recurrent laryngeal nerve injury.
• 87.5% of injured patients had transient lesions with recovery within 12 weeks; 12.5% had permanent lesions.
• Higher injury rates observed in huge goiters and during total thyroidectomy procedures.

Conclusions:

• Thyroid surgery requires experienced surgeons to minimize complications.
• Extra caution is advised for patients with huge goiters and those undergoing total thyroidectomy to prevent nerve injury.
