Thyroid disease is more common in young women. Traditional surgical scars may affect the appearance of patients and cannot fully meet the cosmetic needs of patients. With the advancement of surgical techniques, endoscopic thyroid surgery has developed rapidly. Trans oral endoscopic thyroidectomy vestibular approach is feasible and safe to achieve no scar on the body surface, but there are some unavoidable limitations, such as postoperative numbness and discomfort in the center of the chin region. As a new approach to thyroid surgery, trans oral endoscopic thyroidectomy submental access has the same advantages as the trans oral vestibular approach from top to bottom, and can reliably and thoroughly dissect lymph nodes in the central area (especially area Ⅶ), allowing larger specimens to be taken out and expands the indications for surgery, minimizes flap detachment, and avoids jaw pain and numbness. Trans oral endoscopic thyroidectomy submental access is an innovation in the concept of thyroid surgery, which achieves minimally invasive and aesthetic results on the premise of ensuring the quality of the surgery and curing the disease. We reviewed the history, advantages and disadvantages of trans oral endoscopic thyroidectomy submental access.
Objective To investigate the effectiveness of a novel lateral tibial plateau annular plate (hereinafter referred to as the novel plate) fixation via fibular neck osteotomy approach for posterolateral tibial plateau fractures. Methods Between January 2015 and December 2018, 22 patients with posterolateral tibial plateau fractures were treated. There were 10 males and 12 females with an average age of 39.0 years (range, 25-56 years). Seven fractures were caused by falls, 10 by traffic accidents, and 5 by falling from height. The time from injury to hospitalization ranged from 3 to 12 days, with an average of 7.0 days. All patients were closed fractures. According to Schatzker classification, the fractures were classified as type Ⅱ in 8 cases, type Ⅲ in 9 cases, type Ⅴ in 1 case, and type Ⅵ in 4 cases. The fractures were fixed with the novel plates after reduction via fibular neck osteotomy approach. The fracture reduction and healing were observed by X-ray film after operation. The range of motion of the knee joint was recorded and the function was evaluated by modified American Hospital for Special Surgery (HSS) score. Results All operations were completed successfully. The operation time was 60-95 minutes (mean, 77.6 minutes). The intraoperative blood loss was 100-520 mL (mean, 214.5 mL). There was 1 case of common peroneal nerve injury during operation and 2 cases of fat liquefaction of incision after operation. All patients were followed up 13-32 months (mean, 19.4 months). Postoperative X-ray films showed that the fracture reduction was good in 17 cases and moderate in 5 cases, and all fractures healed with a healing time of 10-18 weeks (mean, 13.0 weeks). At last follow-up, the range of motion of the knee joint ranged from 100° to 145° in flexion (mean, 125.5°) and from 0° to 4° in extension (mean, 1.2°). The modified HSS score was 82-95 (mean, 86.3). There was no complications such as plate deformation, screw fracture, fracture reduction loss, skin necrosis, and so on. Conclusion For posterolateral tibial plateau fractures, the novel plate fixation via fibular neck osteotomy approach has the advantages of clear intraoperative field, firm fracture fixation, and less postoperative complications, which is beneficial to the recovery of knee joint function.
From Jan. 1991 to Jan. 1994, 11 cases ofdifferent hip lesions with flexon contracture deformity were treated by combination of SmithPeterson and WatsonJones incisions in replacement of hip joint. All of them were followed-up for 1 to 3 years (an average of 1.9 years). According to pain, joint function, the excellent and good results were rated at 90.9%. This showed that from using the combined incisions, the hip joint was very well exposed, and release of hip flexion contracture could be acomplished in the same time. Bleeding fromoperation was reduced and the procedure was simple.
Objective To measure the anatomical parameters related to lumbar unilateral transverse process-pedicle percutaneous vertebral augmentation, and to assess the feasibility and safety of the approach. Methods A total of 300 lumbar vertebral bodies of 60 patients were randomly selected, and vertebral augmentation were simulated 600 times on X-ray and CT image with unilateral conventional transpedicle approach (control group) and unilateral transverse process-pedicle approach (experimental group). The distance between the entry point and the midline of the vertebral body, the puncture inner inclination angle, the safe range of the puncture inner inclination angle, and the puncture success rate were measured and compared between the left and right with the same approach, and between the two approaches. Results The distance between the entry point and the midline gradually increased from L1 to L5 on both sides in the 2 groups. In the control group, the right sides distance of L1 and L2 was much longer than the left sides, and the right sides distance of L1, L2, and L5 was much longer than the left sides in the experimental group (P<0.05); the distance of the experimental group between the entry point and the midline was much longer than the control group regardless of the sides from L1 to L5 (P<0.05). In the experimental group, the right maximum inner inclination angle from L1 to L5, the right middle inner inclination angle from L1 to L5, and the right minimum inner inclination angle from L1, L2, L4, L5 were significantly larger than the left side (P<0.05). The maximum inner inclination angle and the middle inner inclination angle presented increased tendency, the tendency of minimum inner inclination angle was ambiguous, however, the all inner inclination angles were much larger than those in control group among the different lumbar levels(P<0.05). There was no significant difference of the safe range of the puncture inner inclination angle between 2 sides in 2 groups at L1 to L5 (P<0.05); the safe range angle in experimental group at L5 was significantly smaller than that in control group (P<0.05). The difference in total puncture success rate of all lumbar levels was significant between the experimental group and the control group (χ2=172.252, P=0.000); the puncture success rates of the experimental group were higher than those in the control group form L1 to L4 (P<0.05), but no significant difference was found in the puncture success rate between 2 groups at L5 (P>0.05). Conclusion Compared with the unilateral conventional transpedicle approach, the entry point of the unilateral transverse process-pedicle approach is localized outside, the puncture inclination angle is wider, and the puncture success rate is higher. It shows that the unilateral transverse process-pedicle approach is safer and more reliable than the unilateral conventional transpedicle approach.
ObjectiveTo investigate the feasibility of dissecting the external branch of the superior laryngeal nerve using endoscopic thyroidectomy via gasless unilateral subclavian approach combined with intraoperative nerve monitoring. MethodsThe clinical data of 30 patients who underwent the gasless nilateral subclavian approach endoscopic thyroidectomy in the Department of Head and Neck Surgery, Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine from October 2023 to February 2024 were retrospectively analyzed. ResultsAll operations were successfully completed under endoscopy approach without transfer to open surgery. A total of 29 cases of the external branch of superior laryngeal nerves were revealed in 30 cases, the revealed rate was 96.7%. The time for dissecting the external branch of the superior laryngeal nerve was 2–6 min [(3.6±2.3) min]. There was no obvious sound change related to the injury of the external branch of superior laryngeal nerve in postoperative patients. ConclusionFor the modified endoscopic thyroidectomy via gasless unilateral subclavian approach combined with intraoperative nerve monitoring, excellent anatomical protection of the external branch of the superior laryngeal nerve can be obtained.

ObjectiveTo investigate the effectiveness of modified Stoppa approach with medial wall spring plate (MWSP) for involving quadrilateral of acetabulum fracture. MethodsBetween March 2008 and September 2013, 38 patients with involving quadrilateral of acetabulum fracture were treated, including of 23 males and 15 females with an average age of 36.08 years (range, 19-56 years). The causes included traffic accidents injury (21 cases), crash injury of heavy object (10 cases), and falling injury from height (7 cases). The interval of injury and admission was 3 hours to 2 days (mean, 11 hours). There were 12 cases of anterior column fracture (type D), 5 cases of transverse fractures (type E), 8 cases of T shaped fractures (type H), 6 cases of anterior column fracture with posterior transverse fractures (type I), and 7 cases of double column fractures (type J) according to Letournel-Judet classification. Based on fracture types, MWSP was used to fix fracture by modified Stoppa approach in 19 cases or combined with the ilioinguinal approach in 10 cases or combined with Kocher-Langenbeck approach in 9 cases. The operation time, blood loss, and complications were recorded. The effectiveness of reduction and the hip function were evaluated according to Matta score system and Merled' Aubigne and Postel score system. ResultsThe operation time was 85-210 minutes (mean, 130 minutes).The intra-operative blood loss was 450-900 mL (mean, 650 mL). There were 1 case of vascular avulsion, and 1 case of bladder injury during operation; there were 8 cases of venous thrombosis and 2 cases of fat liquefaction of incision after operation. Screw was implanted into the articular joint in 1 case on CT after operation. Matta X-ray assessment showed anatomical reduction in 9 cases, satisfactory reduction in 24 cases, and unsatisfactory reduction in 5 cases, and the satisfaction rate of reduction was 86.84%. Three patients had limb shorting of 0.8-1.0 cm when compared with normal limb. All patients were followed up for 7 to 18 months with an average of 10 months. Fractures healed well within 13-16 weeks with an average of 14 weeks. At 1 year after operation, the results were excellent in 9 cases, good in 21 cases, general in 5 cases, and poor in 3 cases, and the excellent and good rate was 78.95% according to the Merled'Aubigne and Postel hip score standards. ConclusionInvolving quadrilateral of acetabulum fracture can be fixed with MWSP by modified Stoppa approach or combined with other approaches to obtain good exposure, less invasion, satisfactory reduction, stable fixation, and low complications.
ObjectiveTo explore the effectiveness of annular ligament reposition and repair via Henry’s approach for Monteggia fracture in children.MethodsA clinical data of 21 children with Monteggia fractures was retrospectively analysed, who underwent open reduction of the radial head and annular ligament reposition and repair via Henry’s approach between May 2015 and July 2019. There were 11 boys and 10 girls with an average age of 8 years and 1 month (range, 4 years and 5 months to 14 years and 4 months). The fracture was caused by falling in 17 cases and by falling from height in 4 cases. There were 16 fresh fractures and 5 old fractures. The Monteggia fractures were rated as Bado typeⅠin 14 cases and Bado type Ⅲ in 7 cases. Preoperative MRI examination and intraoperative observation confirmed that the annular ligament was intact. After operation, the fracture healing, elbow range of motion (ROM), and complications were recorded, and the effectiveness was evaluated according to the Mackay’s function scoring system.ResultsThe incisions healed by first intention after operation, and there was no complication such as radial nerve injury. All children were followed up 12-25 months, with an average of 15 months. No dislocation or subluxation of the radial head occurred after operation. At last follow-up, the ROM of elbow flexion and extension of the children with old fractures increased from (92.6±11.2)° before operation to (123.6±11.6)°, and the ROM of forearm rotation from (96.8±11.8)° to (129.8±5.9)°; the differences between pre- and post-operation were significant (t=7.672, P=0.002; t=9.487, P=0.001); the ROM of elbow flexion and extension of the children with fresh fractures was 139°-156° (mean, 145°); the ROM of forearm rotation was 158°-168° (mean, 162°). According to Mackay’s criteria, 17 cases were excellent and 4 cases were good, with an excellent and good rate of 100%. X-ray film examination showed no nonunion, heterotopic ossification, or loosening of internal fixation after operation. The ulnar fracture and the ulnar osteotomy healed in all cases.ConclusionThe annular ligament in Monteggia fractures in children is intact. Compared with the reconstruction of the annular ligament, the reposition and repair of the annular ligament via Henry’s approach is closer to the original anatomical state of the annular ligament and has the advantages of less trauma and fewer complications.
Objective To observe the cl inical results of treatment of Schatzker V/VI tibial plateau fracture involved posteromedial condyle through combined posteromedial and anterolateral approach and fixed with two or three plates. Methods From April 2005 to April 2008, 18 cases of tibial plateau fracture involved posteromedial condyle were treated, including 14 males and 4 females with an average age of 38.5 years old (range, 18-62 years old). According to Schatzker classification, there were 12 cases of type V and 6 cases of type VI. The posteromedial condyle were involved in 13 cases and bilateral posterior condyle in 5 cases. All patients were given posteromedial fragment and medial condyle fracture reduction through posteromedial approach firstly, and then lateral condyle fracture reduction through anterolateral approach, and injury of meniscuses and cruciate l igaments were treated at the same time. Three plates (lateral, medial, posterior) were used in 10 cases and two plates (lateral, posteromedial) in 8 cases. Results All wounds achieved heal ing by first intention without compl ications such as infection, flap necrosis, osteofascial compartment syndrome, chronic osteomyel itis, nonunion. All patients were followed up for 12 to 48 months with an average of 24.4 months. The mean flexion of the knee was 118.4° (range, 100-130°) 1 year after operation. According to Iowa evaluation system, 12 patients got excellent results, 4 good, and 2 fair; the excellent and good rate was 88.9%. Conclusion Combined posteromedial and anterolateral approach and fixed with two or three plates is effective in treatment of the Schatzker V/VI tibial plateau fracture involved posteromedial condyle. Anatomical reduction and rigid internal fixation of the posteromedial fragment are critical to successful operation.
