Article Abstract

Introduction: Metachronous lateral neck recurrence after thyroidectomy for N1b papillary thyroid cancer is accompanied by high morbidity and increased difficulty of reoperation. From the perspective of recurrence, the objective of this study was to compare patients who underwent metachronous lateral neck dissection (mLND) despite initial thyroidectomy and patients who underwent synchronous lateral neck dissection (sLND) for papillary thyroid cancer and analyze the risk factors for recurrence after mLND.

Method: This retrospective study involved 1,760 patients who underwent lateral neck dissection for papillary thyroid cancer at the Gangnam Severance Hospital, a tertiary medical center in Korea, from June 2005 to December 2016. The primary outcome was structural recurrence, and secondary outcome measures were risk factors of recurrence in the mLND group.

Result: A total of 1,613 patients underwent thyroidectomy and sLND at diagnosis. In 147 patients, thyroidectomy alone was performed at the time of diagnosis, and mLND was performed when recurrence to the lateral neck lymph node was confirmed. During a median follow-up of 102.1 months, 110 (6.3%) patients experienced a recurrence. There was no significant difference in the recurrence between the sLND and mLND groups (6.1% vs 8.2%, P=.32). The period from lateral neck dissection to recurrence was longer in the mLND group than in the sLND group (113.6 ± 39.4 months vs 87.0 ± 33.8 months, respectively, P<.001). Age ≥50 years (adjusted HR=5.209, 95% CI=1.359-19.964; P=.02), tumor size >1.45 cm (adjusted HR=4.022, 95% CI=1.036-15.611; P=.04), and lymph node ratio in the lateral compartment (adjusted HR=4.043, 95% CI=1.079-15.148; P=.04) were independent variables predictive of recurrence after mLND.

Conclusion: mLND is suitable for treating lateral neck recurrence in patients with N1b papillary thyroid cancer who previously underwent thyroidectomy. Lateral neck recurrence after treatment in patients who underwent mLND was predicted by age, tumor size, and lymph node ratio in the lateral compartment.

Background: Cervical spine radiography is a common screening tool for cervical spondylosis with radiographic features, including osteophytes, disc height narrowing, vertebral sclerosis, and spondylolisthesis. The Kellgren-Lawrence classification is widely used for evaluating musculoskeletal radiographs, including spinal radiographs; however, evaluating the individual radiographic features of spondylosis is challenging with this classification. This study aimed to develop an elemental grading system for evaluating cervical spine radiographs and the extent of cervical spondylosis.

CBCT Analysis of Incisor Movement and Alveolar Bone Changes in Class II Malocclusion Treatment with Premolar Extraction using Clear Aligner: A Retrospective Study.

J Dent

September 2025

State Key Laboratory of Oral Diseases & National Clinical Research Center for Oral Diseases; Department of Orthodontics, West China Hospital of Stomatology, Sichuan University, Chengdu, China.. Electronic address:

Objectives: This retrospective study evaluates alveolar bone remodeling patterns and their association with incisor displacement in adults undergoing clear aligner therapy with premolar extractions for Class II malocclusion correction.

Methods: Cone-beam computed tomography (CBCT) scans of 38 maxillary and 37 mandibular incisors were analyzed. Displacement vectors for four anatomical landmarks (cusp tip [C], root apex [R], root neck midpoint [M], labial cementoenamel junction [L]) were quantified.

Diagnostic and Therapeutic Strategies for Intraoperative and Postoperative Hypocalcemia in Pediatric Thyroidectomy Patients: A Single-Center Experience.

J Pediatr Surg

September 2025

Department of Pediatric and Adolescent Endocrinology, Chair of Pediatrics, Institute of Pediatrics, Jagiellonian University Medical College, Krakow, Poland; Department of Pediatric and Adolescent Endocrinology, University Children's Hospital of Krakow, Krakow, Poland.

Background: The primary goals of surgical management in thyroid disorders are the treatment of malignancy, goiter, and thyrotoxicosis, while adhering to the principle of 'primum non nocere'. Hypocalcemia is among the most common complications, primarily resulting from inadvertent injury to the parathyroid glands.

Methods: A retrospective analysis of 2015-2023 records of Polish pediatric patients who underwent thyroid surgery.

Relationship between timing of tympanostomy tube insertion and mastoid air cell development in children with otitis media.

Objective: This study aimed to evaluate the effect of age at tympanostomy tube insertion on mastoid air cell development, focusing on whether insertion before 3 years of age is associated with more favorable pneumatization.

Methods: We retrospectively analyzed 39 children (71 ears) who developed tympanic membrane perforation following tube insertion (tube group), including cases primarily associated with recurrent acute otitis media (rAOM) and otitis media with effusion (OME). The control group consisted of 41 children (41 ears) with congenital cholesteatoma, using their contralateral normal ears as controls.

Biomechanical Evaluation of the Risk of Subtrochanteric Fracture After Femoral Neck Fixation in a Synthetic Model: The Femoral Neck System versus Cannulated Screws.

J Am Acad Orthop Surg

August 2025

From the Department of Orthopedic Surgery (Kuttner), Ohio State University, Columbus, OH, the Department of Orthopedic Surgery (Cancio-Bello, Thompson, Sems, Cross, Hidden, Yuan), Mayo Clinic, Rochester, MN, and the Biomechanics Laboratory (Fitzsimmons, Berglund), Department of Orthopedic Surgery, M

Objectives: The Femoral Neck System (FNS) is a fixed-angle side plate device approved for use in fixation of femoral neck fractures. The FNS perforates the lateral cortex of the subtrochanteric femur, which may increase the risk of postoperative subtrochanteric fractures compared with the inverted triangle cannulated screw (CS) construct. The purpose of this biomechanical study was to compare forces required to create subtrochanteric fractures in FNS and CS constructs in a synthetic bone biomechanical model.
