Retrograde cricopharyngeal dysfunction (RCPD) is a fairly recently described condition that has been gaining traction online. Majority of patients arrive at the diagnosis themselves, after undergoing numerous inconclusive investigations, in…

[BACKGROUND] An increasing number of younger individuals are now seeking facelift procedures not only for rejuvenation but also to enhance facial contours, particularly periorbital aesthetics and midface projection, while effective, endosco…

The endoscopic brow lift delicately alters the balance between the elevator and depressor musculature of the brow-forehead complex to elevate the position of the brow, reduce rhytids, and achieve improved symmetry of the brows. Wide subperi…

[BACKGROUND] Breast augmentation with implants is commonly performed among East Asian patients, but few studies have analyzed how breast morphology changes postoperatively. This study evaluated these changes in this population. [METHODS] T…

In recent years, endoscopic upper and midface rejuvenation techniques have advanced dramatically with the advent of endoscopic dissection in the sub-SMAS plane. The temporal tunnel approach exploits this tissue plane in the midface via a sm…

[BACKGROUND & AIMS] For the local excision of early rectal tumors (ERTs), the relative effectiveness of endoscopic submucosal dissection (ESD) vs transanal endoscopic microsurgery (TEM) is subject to debate. The comparisons are limited to r…

The management of pineal gland tumors poses unique surgical challenges, with varying approaches and outcomes across centers. The existing data on surgical strategies for these tumors are limited, with conflicting information regarding treat…

[BACKGROUND] Long-segment tracheal defects present complex reconstructive challenges due to the risk of airway collapse and disrupted mucociliary clearance. Osteocutaneous radial forearm free flaps (RFFFs) offer a promising alternative to t…

We present a coaxial fiber probe that integrates optical coherence tomography ranging and fiber Bragg grating force sensing within a single-mode fiber, enabling synchronized distance-force feedback for minimally invasive interventions. A sh…

[BACKGROUND] The surgical management of vestibular schwannoma (VS) has shifted focus from mortality reduction to functional preservation and quality of life. While the traditional microscopic retrosigmoid approach is the gold standard, it s…

[BACKGROUND] The correction of breast ptosis using implants alone remains controversial. Given the preference for transaxillary approaches among Asian women, we developed a novel technique: endoscopic-assisted transaxillary high dual-plane …

[PURPOSE] This study aimed to evaluate oncological outcomes in patients with high-risk early rectal cancer undergoing local excision, comparing those who received guideline-recommended additional treatment to those who did not, either due t…

[PURPOSE] Recent evidence suggests that the local recurrence (LR) rate after local excision of pT1 rectal adenocarcinoma may be higher than previously estimated, particularly in large cohorts with extended follow-up. This study aimed to eva…

Study DesignScoping review.ObjectiveTo review the literature on complications related to uniportal and unilateral biportal endoscopic techniques for lumbar spinal stenosis, identify areas needing further clarification, and enhance the under…

[BACKGROUND] Comparison of Transanal Endoscopic Microsurgery (TEM) and Endoscopic Submucosal Dissection (ESD) is based only on retrospective studies. With the aim of comparing the effectiveness of TEM and ESD, a single-center randomized cli…

[BACKGROUND/AIMS] Both endoscopic resection (ER) and transanal surgery (TAS) are minimally invasive treatment options that allow organ preservation in early rectal tumors. We conducted a meta-analysis to compare treatment outcomes between t…

This video demonstrates endoscopic transnasal "microsurgery" for a suprasellar meningioma involving the anterior communicating artery complex. A 44-year-old woman presented with visual loss due to a suprasellar tumor. Preoperative three-dim…

[OBJECTIVE] To analyze the results of transanal endoscopic and robotic microsurgery for rectal neoplasms. [MATERIAL AND METHODS] A retrospective cohort study enrolled 84 patients. We considered clinical and anamnestic data, anatomical char…

[UNLABELLED] Olfactory meningiomas are common neoplasms accounting for 4.5-18% of all intracranial meningiomas. Currently, transcranial (pterional, unilateral subfrontal, bilateral subfrontal, interhemispheric and through the frontal sinus)…

Recent advances in imaging technologies have transformed surgical practice, enabling more accurate diagnoses, refined perioperative planning, and improved patient outcomes. In oculofacial plastic surgery, these tools provide safer and more …
