Transoral Endoscopic thyroidectomy: our initial experience using a New Endoscopic Technique
Surgical Endoscopy, 2017Co-Authors: Jun-ook Park, Dong-il SunAbstract:Background A transoral approach has been experimentally introduced to the field of thyroid surgery and several groups in Asia have recently used the Technique to treat patients. We performed transoral Endoscopic thyroidectomies on patients with thyroid cancer or a benign tumor. Methods We reviewed the medical records of patients who underwent transoral Endoscopic thyroid surgery between July 2016 and January 2017. A midline incision was made in the vestibule, and a 10 mm cannula was placed; then, the working space was widened by insufflating CO_2 at a pressure of 5–6 mmHg. Two lateral incisions were made in the vestibule near the first molars, and 5-mm-diameter cannulas were inserted. A 10-mm 30° telescope was inserted through the midline cannula and instruments were positioned through the lateral cannulas. Thyroid surgery was Endoscopically performed using conventional Endoscopic instruments. Results We performed 18 thyroid surgeries (15 thyroid lobectomies, one completion thyroidectomy, and two total thyroidectomies) in 17 patients. The postoperative pathology was papillary thyroid cancer in 11 cases (61.1%), a follicular carcinoma in two cases (one patient) (11.1%) and benign in five cases (27.8%). The average tumor diameter was 1.75 cm (range 0.5–7.5 cm). No patient reported sensory changes around the lower lip. No patient developed permanent recurrent laryngeal nerve palsy or hypocalcemia. No patient developed a wound infection or a fistula between the oral incision and anterior neck. Conclusions The transoral Endoscopic approach provides a short, direct route to the thyroid gland and seems to be safe and feasible. It is important to further develop and refine the surgical Techniques. The approach is optimal, and will become widely used for thyroid surgery in the near future.

Endoscope-assisted facelift thyroid surgery: an initial experience using a New Endoscopic Technique
Surgical Endoscopy, 2015Co-Authors: Jun-ook Park, Sang-yeon Kim, Byung-joon Chun, Young-hoon Joo, Kwang-jae Cho, Young Hak Park, Min-sik Kim, Dong-il SunAbstract:Background A New approach to modifying facelift incision was recently developed for robotic thyroid surgery that seemed to be advantageous over other existing approaches. In this study, we aimed to investigate the feasibility and safety of the facelift approach not only for robotic thyroid surgery, but also for endoscope-assisted thyroid surgery. Methods Endoscope-assisted facelift thyroid lobectomy was performed for 11 patients with papillary microcarcinoma. Results All 11 operations were successfully performed Endoscopically. This approach through a modified facelift incision provided safe dissection of the laryngeal nerves and exposed an adequate working space. We identified and preserved all neighboring critical structures (parathyroid gland and superior and recurrent laryngeal nerves) during surgery. The operative duration for simple thyroid lobectomy with central lymph node dissection in 11 patients was 120–180 min (average duration: 140 min). Sensory change around the earlobe occurred in three patients and was recovered within 2 months after surgery in all patients. No patient displayed laryngeal nerve palsy or a low-pitched voice. Conclusions The facelift approach seems to provide a shorter and more direct route to the thyroid, requiring minimal dissection, and an adequate workspace not only for robotic surgery but also for Endoscopic surgery. It is worthwhile to develop and refine the surgical Techniques of Endoscopic facelift thyroid surgery.

A novel Endoscopic Technique in treating single nerve entrapment syndromes with special attention to ulnar nerve transposition and tarsal tunnel release: clinical application.
Neurosurgery, 2006Co-Authors: Kartik G Krishnan, Thomas Pinzer, Gabriele SchackertAbstract:Objective To describe a simple retractor integrated Endoscopic Technique for treating idiopathic solitary compression neuropathies with special attention to the anterior transposition of the ulnar nerve and tarsal tunnel release, and to present the clinical results. Methods Eleven patients with ulnar sulcus syndrome, eight with tarsal tunnel syndrome, and one with meralgia paraesthetica (seven females and 13 males; age range, 12-64 yr) were treated with Endoscopic anterior ulnar nerve transposition and in situ decompression of the tibial (eight patients) and lateral femoral cutaneous nerves (one patient), respectively. The selection criteria were: classical nerve compression symptoms, failed conservative treatment, abnormal electrophysiology, and a nonviolated anatomic region. The degree of nerve compression (after Dellon) was rated as moderate in five out of 20 patients and as severe in 15 out of 20 patients. Electrophysiological studies were conducted independently by physicians specializing in these Techniques. Postoperative recovery was evaluated according to the nine-point Bishop rating system. Results Of the 11 patients with anterior ulnar nerve transposition, seven scored excellent, three scored good, and one scored fair (mean follow-up, 15.5 mo; range, 6-27 mo). Five patients with tarsal tunnel release scored excellent and three scored good (mean follow-up, 10.1 mo; range, 3-24 mo). The patient with meralgia paraesthetica showed an excellent score at 28 months after surgery. There were no technical or postoperative complications. None of the operations had to be converted to open surgery. Conclusion We describe a New Endoscopic Technique for transposing the ulnar nerve and decompressing the tibial nerve. This Technique could be extrapolated to release other single nerve entrapments. The simplicity of the Technique, and our preliminary clinical results, may encourage other groups to adapt this method.

Surgical Technique: Endoscopic Gluteus Maximus Tendon Release for External Snapping Hip Syndrome
Clinical Orthopaedics and Related Research®, 2013Co-Authors: Giancarlo Cavalli Polesello, Marcelo Cavalheiro De Queiroz, Benjamin G. Domb, Nelson Keiske Ono, Emerson Kiyoshi HondaAbstract:Background While many authors have recommended surgery for patients with persistent symptoms of external snapping hip, it is unclear which one best relieves symptoms. Concerns with iliotibial band (ITB)-modifying Techniques include altering the shape of the lateral thigh and overload of the contralateral abduction mechanism. We describe a New Endoscopic Technique that decreases the tension of the ITB complex by releasing the femoral insertion of the gluteus maximus tendon (GMT). Description of Technique Via an Endoscopic approach, we tenotomize the GMT near its insertion at the linea aspera through two trochanteric portals, developing a space beneath the ITB. Methods We reviewed eight patients (nine hips) with external snapping hip nonresponsive to nonoperative treatment treated by Endoscopic GMT release. There were seven women (one bilateral) and one man, with a mean ± SD age of 35 ± 13.1 years (range, 18–55 years). Mean symptom duration was 36 ± 20.3 months (range, 16–84 months). Minimum followup was 22 months (mean, 32 ± 9.3 months; range, 22–45 months). Results Snapping and pain resolved in seven patients after the initial procedure. We performed one revision procedure with complete relief of symptoms. All eight patients returned to their previous level of activity. Average modified Harris hip score was 61 points (range, 45–70 points) preoperatively and 78 points (range, 62–93 points) at latest followup. We observed no neurovascular complications. Conclusions Our small series suggests Endoscopic release of the GMT resolves pain and snapping symptoms in most patients. Level of Evidence Level IV, therapeutic study. See Instructions for Authors for a complete description of levels of evidence.
