What the literature leaves open

  • One of the challenges is that preexisting voice problems can alter the interpretation of results after thyroidectomy. Another challenge is the lack of standard and specific methods to evaluate voice changes after thyroid surgery. The study also faces the challenge of comparing results across different studies due to the lack of standard methods.

    Voice changes following uncomplicated thyroid surgery: a prospective study in Iranian people · 2026 · DOI

  • The gap in current understanding is how frequency, independent of power and thermal dose, influences thermal safety in endoscopic laser lithotripsy. There is a need to consider factors beyond cumulative thermal dose, such as energy delivery methods, in assessing thermal safety.

    Thermal safety in endoscopic laser lithotripsy: frequency deserves equal attention to power and thermal dose · 2026 · DOI

  • The duration of recovery after surgical trauma is unclear. There is a lack of understanding of the changes in thyroid hormones and serum albumin after cardiac interventions.

    Longitudinal Changes in Thyroid Hormones and Serum Albumin Following CABG, AVR, and PCI: An Exploratory Electronic Medical Record Study · 2026 · DOI

  • The application of bipolar sealing technology to elastin-rich tissues is unclear. There is a lack of understanding of the possibilities and limitations of energy-assisted sealing technologies in elastin-rich tissues.

    Experimental Investigation into Bipolar Sealability of Elastin-Rich Tissue · 2026 · DOI

  • The surgical and pathological impact of ablation-induced remodeling remains incompletely defined.

    Fibrosis‐Driven Surgical Risk After Thyroid Nodule Ablation: Quantitative Clinicopathological Determinants of Complications in Post‐Ablative Thyroidectomy—A Retrospective Cohort Study · 2026 · DOI

  • How patients weigh these risks against cervical scarring and wound morbidity from open surgery remains unclear.

    Tailoring the Message: A Survey of Patients' Information Needs and Preferences Before Transoral Endoscopic Thyroidectomy via the Vestibular Approach · 2026 · DOI

  • The influence of age on postoperative risk, across the spectrum from pediatric to adult patients, remains incompletely defined.

    Pediatric Increased Risk and Nonlinear Age‐Dependent Risk of Hypoparathyroidism After Total Thyroidectomy: A 1914‐Patient Cohort Study · 2026 · DOI

  • Surgeons have since started to use PRRT as a neo-adjuvant option, although large trials are lacking some evidence supports this treatment.

    Five Advances in the Last 50 Years That Have Impacted Endocrine Surgery · 2026 · DOI

  • International consensus guidelines for standard pHPT were first developed in 1990 and have since been re-developed; however, specific guidance on normocalcaemic HPT is still lacking.

    Five Advances in the Last 50 Years That Have Impacted Endocrine Surgery · 2026 · DOI

  • Although energy-based devices are widely used during glandular procedures, their tissue-level effects remain insufficiently defined.

    Comparison of Histological Effects of LigaSure and Bipolar Cautery on the Submandibular Gland in a Rat Model · 2026 · DOI

  • Although the limited data and its retrospective nature, this study emphasises the usefulness of the PTH FNA-US washout method in the preoperative diagnosis of primary hyperparathyroidism.

    EP1754 - LBA_ECE_1086 - The value of PTH fine needle aspiration washout in the preoperative diagnostic work-up of primary hyperparathyroidism: a retrospective real-life study · 2026 · DOI

  • Tissue exposure to cold temperatures is common in clinical practice, yet the safety of exposing the recurrent laryngeal nerve (RLN) to cold remains unclear.

    Cold Exposure to the Recurrent Laryngeal Nerve: A Porcine Continuous Intraoperative Neuromonitoring Model Study · 2026 · DOI

  • Management of recurrent laryngeal nerve (RLN) invasion by thyroid cancer remains controversial between shaving the tumor and resecting it.

    Shaving Versus Resection on Recurrent Laryngeal Nerve in Thyroid Cancer Surgeries: A Systematic Review and Meta‐Analysis · 2026 · DOI

  • The effect of topical intraoperative corticosteroid application on voice quality in thyroid surgery with preserved RLN remains unclear.

    A Randomized Controlled Trial to Evaluate the Effects of Topical Intraoperative Corticosteroid Application on Voice Quality in Thyroid Surgery With Preserved Recurrent Laryngeal Nerves · 2025 · DOI

  • Whether parathyroidectomy is associated with lower risk of diabetes has not been evaluated in a large cohort.

    Parathyroidectomy and Risk of Incident Diabetes in Patients With Primary Hyperparathyroidism · 2025 · DOI

  • However, the relationship between enhancement patterns and histologic features such as lesion cellularity remains unclear.

    Correlation between 4D-CT Enhancement Patterns and Parathyroid Adenoma Cellularity: A Retrospective Study · 2025 · DOI

  • For Q II (optimal treatment of chronic HypoPT), relevant data regarding conventional treatment are lacking for clinically relevant endpoints and long-term effects.

    Revised European Society of Endocrinology Clinical Practice Guideline: Treatment of Chronic Hypoparathyroidism in Adults · 2025 · DOI

  • As HypoPT is an orphan disease, strong evidence for most outcomes is scarce and recommendations were based on careful synthesis of the literature and expert opinion.

    Revised European Society of Endocrinology Clinical Practice Guideline: Treatment of Chronic Hypoparathyroidism in Adults · 2025 · DOI

  • The underlying pathogenic pathways linking hypercalcemia and parathyroid hormone (PTH) excess to the co-presence of the neuropsychiatric symptoms are poorly understood. There is no standardized approach recommended and no distinct recommended instrument so far (at guideline level) for assessing depression and anxiety in PHPT.

    An Analysis of Primary Hyperparathyroidism in Association with Depression or Anxiety · 2025 · DOI

  • The number of fragments per pocket varied widely and the most common site for placement was the sternocleidomastoid muscle (90%).
