HYPOTHESIS: Video-assisted thyroid lobectomy improves the cosmetic outcome of the cutaneous scar and reduces postoperative pain. PARTICIPANTS: Patients admitted to the Division of Endocrine Surgery of the Università Cattolica del Sacro Cuore, Rome, Italy, between March 1999 and December 2000 who were candidates for thyroid lobectomy because of a single, small (< or = 3 cm) thyroid nodule were considered eligible. Of the 62 patients who were randomized, 31 underwent conventional thyroid lobectomy (COS group), and 31 underwent video-assisted surgery without carbon dioxide neck insufflation (VAS group), a new technique created by the authors. RESULTS: The cosmetic outcome was evaluated by scoring patients' satisfaction with their scars. Satisfaction was higher in the VAS group (mean +/- SD, 9.2 +/- 0.5) than the COS group (mean +/- SD, 5.8 +/- 0.7) (P<.001). Postoperative pain in the first and second days after surgery was lower in the VAS group (mean +/- SD, 1.8 +/- 0.2 and 1.2 +/- 0.1, respectively) than in the COS group (mean +/- SD, 6.2 +/- 0.2 and 5.8 +/- 0.2, respectively) (P<.001). There were no significant differences in complications (eg, bleeding, wound infection, permanent recurrent nerve palsy). Postoperative hospital stay was lower in the VAS group (mean +/- SD, 1.1 +/- 0.1 days) than in the COS group (mean +/- SD, 2.2 +/- 0.2 days) (P<.05). CONCLUSION: Video-assisted thyroid lobectomy is a valid alternative to conventional surgery in patients with single, small nodular thyroid lesions.
BACKGROUND AND OBJECTIVE: Scar sarcoidosis is a circumscribed form of cutaneous sarcoidosis, which is often very difficult to treat. To date, therapeutic approaches have yielded little success and often been accompanied by adverse effects, some of which are severe. Laser treatment is one alternative, which has proven to be effective in a dramatically increasing number of cases over the past years. STUDY DESIGN/MATERIALS AND METHODS: We report about a 50-year-old female patient who presented with histologically confirmed scar sarcoidosis on the right elbow and both knees; the sarcoidosis had spontaneously developed on three sites which had traumatic tattoos from abrasions. Because of the reddish-brown livid discolorations, we treated the granulomas with the pulsed dye laser for three sessions, although without success. Treatment with the Q-switched ruby laser was commenced to remove the traumatic tattoos. RESULTS: Not only had the areas lightened fully after four sessions, the sarcoidosis foci had resolved completely, and the patient has been recurrence-free for over 3 years. CONCLUSION: The Q-switched ruby laser appears to be a rapid and effective means of treating scar sarcoidosis with traumatic tattoos without incurring adverse effects. The definitive mode of action is still not fully known, however.
