Thyroid surgery: changing patterns of practice.

OBJECTIVE: The practice of thyroidectomy has evolved over the past 10 years with the introduction of minimally invasive surgery, laryngeal nerve monitoring, and outpatient surgery. We sought to investigate corresponding trends in the disciplines performing thyroid surgery. METHODS AND MATERIALS: The authors conducted a nonrandomized, case-controlled comparison of surgical volumes and systematic analysis of publication volumes. Two surrogates for the proportion of thyroidectomies being performed by otolaryngologists-head and neck surgeons (OHNS) and general surgeons (GS) were chosen: 1) the operative case logs of graduates from American training programs in OHNS and GS from 1995 through 2004 were compared; and 2) the number of scientific articles published relating to thyroid surgery were systematically queried for two timeframes (1990-1994 and 2000-2004). RESULTS: There was a gradual increase in the mean number of thyroidectomies performed by GS residents from 13.2 in 1995 to 18.2 in 2004. During the same timeframe, the mean number of thyroidectomies performed by OHNS residents more than doubled from 15.0 to 33.5. The number of American GS thyroid publications from 1990 to 1994 was 79, compared with 98 in the period 2000 to 2004, representing a 24% increase. During the same timeframe, the number of American OHNS articles increased from 14 to 49 (a 250% increase). The relative proportion of thyroid publications authored by American otolaryngologists more than doubled from 15.1% to 33.3% (P = .0017). CONCLUSIONS: A clear trend is emerging in the pattern of thyroid surgery in that a growing proportion of publications are being authored by otolaryngologists compared with general surgeons, and the average number of procedures performed by graduating chief residents is now 84% higher in otolaryngology compared with general surgery.

Ultrasonic technology facilitates minimal access thyroid surgery.

OBJECTIVES: Options for controlling the vasculature during thyroid surgery include suture ligatures, vessel clips, and bipolar cautery. Ultrasonic technology represents an alternative to conventional techniques in which the vessels are simultaneously sealed and divided. We sought to determine the safety and efficacy of thyroidectomy with ultrasonic technology. DESIGN: Nonrandomized, prospective analysis of a series of patients undergoing thyroidectomy at the Medical College of Georgia. METHODS AND MATERIALS: The records of 51 consecutive patients who underwent thyroid surgery between December 2004 and June 2005 were reviewed. Patients in whom ultrasonic technology (Harmonic-ACE, Ethicon Endo-Surgery, Cincinnati, OH) was used comprised the study population. RESULTS: Forty-four of 51 patients underwent thyroidectomy with the assistance of ultrasonic technology. There were 4 males and 40 females with a mean age of 43.5 +/- 15.8 years. Twenty-two patients had a total thyroidectomy, 18 underwent unilateral lobectomy, and 4 underwent completion thyroidectomy. The overall mean incision length was 5.0 +/- 2.6 (range 2-12) cm. A subgroup of patients underwent minimally invasive video-assisted thyroidectomy (n = 13) and had a mean incision length of 29.3 +/- 0.8 mm. There were no cases of permanent injury to the recurrent laryngeal nerve and no cases of persistent hypoparathyroidism. Blood loss ranged from 5 mL to 100 mL, with a mean of 26.7 +/- 21.8 mL. CONCLUSIONS: Ultrasonic technology facilitates thyroid surgery, particularly when a minimally invasive approach is undertaken. It reliably seals and divides the thyroid vasculature and will likely replace other methods of managing the thyroid blood supply.

Percutaneous tracheostomy: don't beat them, join them.

OBJECTIVES: The introduction of percutaneous tracheostomy (PercTrach) has resulted in tension over the scope of practice between otolaryngologists and pulmonary/critical care (PCC) specialists. We sought to determine the value of a collaborative approach to the performance of PercTrach at the bedside in the intensive care unit setting. STUDY DESIGN AND METHODS: A retrospective study of consecutive patients who underwent bedside PercTrach at the Medical College of Georgia between May of 2003 and November of 2003. All cases were performed in conjunction with the PCC team, which typically provided bronchoscopic guidance during the performance of the procedure, whereas the PercTrach was performed by the otolaryngology team, although these roles were occasionally reversed. In all cases, the PercTrach was performed using the Ciaglia Blue Rhino introducer set. RESULTS: Twenty-three patients (12 males, 11 females) with a mean age of 47.6 +/- 14.3 (range 23-65) years underwent PercTrach. The procedural times ranged from 7 to 21 minutes, with a mean of 13.9 +/- 4.4 minutes; this represented 9.6 minutes on average to insert the tracheostomy tube and an additional 4.3 minutes to completely secure the tracheostomy tube. The time interval from consultation to PercTrach was less than 24 hours in 16 of 23 cases (overall mean time to PercTrach = 41.7 +/- 37.1 hours), with delays beyond 24 hours related in most instances to patient stability. CONCLUSION: A multidisciplinary approach to PercTrach results in a number of clinical and educational benefits. Chief among these benefits is a rapid, cost-effective response to requests for elective tracheostomy. Practicing otolaryngologists with a prior bias against this approach (as we had) should reconsider adopting this revised procedure.
