Figure 7: Surgical incisions used to approach deep neck injection
ey Point
K
 The incision over an abscess is usually given over the most uctuant and the most dependent part of it so that spontaneous drainage
occurs in postoperative period thereby preventing pus accumulation in the abscess cavity

ethods
M
 Antiseptic dressing and draping of the operative eld is
done
Oblique incision is given from the tip of 12th rib to the
lateral border of rectus at the level of umbilicus
 Abdominal muscles including EO, IO, TA are split in the
line of incision taking care not to open the peritoneum
Peritoneum is mobilized by retracting the peritoneal sac
medially to expose the retroperitoneal space
 The lumbar sympathetic chain is identied by following
features:
¾ Glistening white appearance ¾ Thick cord like ¾ Lies in groove between psoas muscle and lumbar
vertebral bodies
¾ Presence of ganglia ¾ Bounded by IVC on right side and aorta on the left.
Dissection of sympathetic chain is done using right
angle forceps to reach the 4th ganglia behind the common iliac vessels which is divided at this point
 Haemostasis is achieved  Incision is closed in layers.
Spinal cord

omplications
C
 Breach of peritoneum  Injury to ureter, genital vessels, duodenum, etc.  Bleeding (injury to lumbar veins)  Retroperitoneal hematoma  Incomplete sympathectomy.
ey Points
K
 1st to 4th lumbar ganglia are removed for complete
sympathetic denervation of lower limb but if bilateral procedure is done, then 1st lumbar ganglion is spared to prevent sterility due to failure of ejaculation
 Distance between 1st and 4th lumbar ganglia is
approximately 10 cm
 1st lumbar ganglion lies under cover of crus of diaphragm
while 4th lumbar ganglion is covered by common iliac vessels
 It is a preganglionic surgery for vessels below the knee
because the sympathetic bers supplying these vessels have relay in the sacral ganglia which are not disturbed

shoulder blades with about 10° head up tilt of OT table to reduce venous congestion.
ethods
M
 Antiseptic dressing and draping of the operative field is
done from the level of chin to upper chest
Cervical collar incision is given 2 cm above the
suprasternal notch extending from posterior border of one SCM muscle to the posterior border of other side. The skin incision is marked by pressing a thread over the desired incision area (Garrotte mark)
Skin and platysma are incised to expose the investing
layer of deep cervical fascia

middle thyroid vein is identified, ligated and divided
The superior thyroid vessels are dissected close to
upper pole of lobe and the artery and vein are ligated separately avoiding any damage to external laryngeal nerve
Inferior thyroid artery and vein is identified and

omplications
C
A. Early
¾ Neck hematoma with subsequent airway
compression
¾ Unilateral or bilateral superior/ recurrent laryngeal
nerve injury
¾ Thyroid crisis ¾ Tetany due to parathyroid injury
B. Late
¾ Wound infections ¾ Hypoparathyroidism ¾ Hypertrophic scar ¾ Thyroid insuciency ¾ Stitch granulomas.
ey Points
K
 Mnemonic for indications of surgery:
¾ C-Cosmesis ¾ R-Retrosternal extension ¾ A-Anxiety (symptomatic) ¾ M-Malignancy ¾ P-Pressure symptoms
 Now the current concept is that the inferior thyroid
vessels should be divided as close to the thyroid gland as possible in order to prevent devascularization of parathyroid glands.
 In case of accidental removal of parathyroid gland with the
thyroid tissue, it should be divided into 1 mm fragments and should be re-implanted in sternocleidomastoid muscle.
