Background: Various full-endoscopic techniques have been developed to reach the lateral recess of the lumbar spine. However, specialized surgical tools, including expensive spinal endoscopic systems, and a steeper learning curve to mastering the technique are required.
Method: We present a novel target-addressed unilateral biportal endoscopic technique to reach directly the lumbar lateral recess, particularly useful at L4-L5 and L5-S1. The technique follows an inclined-ipsilateral trajectory to preserve the lateral extension of ligamentum flavum and the facet joint as much as possible.
Conclusion: This technique was associated with all the advantages of minimally invasive decompressive procedures and outstanding outcomes.

Full-Endoscopic Midline Foraminoplasty: An Alternative Method for Treating Lumbar Foraminal Stenosis.
Neurospine
December 2024
Department of Orthopedic Surgery, Navavej International Hospital, Bangkok, Thailand.
Objective: To describe the full-endoscopic lumbar foraminoplasty with midline skin incision (FEFM) and lateral recess decompression procedure and to report its clinical outcomes at the 1-year follow-up.
Methods: Consecutive patients with lumbar foraminal and/or lateral recess stenosis who underwent FEFM procedures were retrospectively reviewed. Clinical outcomes were evaluated with a visual analogue scale (VAS) of back and leg pain and Oswestry Disability Index (ODI) up to 1 year postoperatively.
Characterization of Tip Fold-Over Using Fluoroscopy and Intracochlear Pressure in Cadaver Specimens.
Laryngoscope
December 2024
Department of Otolaryngology, University of Colorado School of Medicine, Aurora, Colorado, U.S.A.
Article Synopsis
- The study examined cochlear implant array malpositioning, particularly focusing on a specific issue called tip fold-over, which can impair speech perception and cause other complications.
- Researchers conducted experiments using cadaveric human heads to measure intracochlear pressure and observe the mechanics of tip fold-over events during the insertion of electrodes.
- Three distinct types of tip fold-overs were identified, with significant pressure changes linked to electrode twisting; this recognition could improve surgical techniques and monitoring during cochlear implant procedures.
Lateral optico-carotid recess as an anatomical landmark for optimal endoscopic optic nerve decompression.

Background: Transnasal endoscopic decompression of the optic nerve is increasingly gaining acceptance among ear, nose, and throat (ENT) surgeons, however neither strict indications for the procedure nor the precise extent of effective decompression have been firmly established to date. This study aimed to determine the distance between endoscopically visible, anatomical structures within the sphenoid sinus and the posterior (i.e.

Department of Otorhinolaryngology-Head and Neck Surgery, Kyung Hee University Hospital, Kyung Hee University College of Medicine, Seoul, Republic of Korea.
Background And Objectives: Sinonasal fungal balls (FBs) most commonly occur in the maxillary sinus, followed by the sphenoid sinus (SS). Relatively little is known about the predisposing factors and pathogenesis of unilateral sphenoid sinus fungal balls (SSFBs) compared to maxillary sinus FBs. We investigated whether anatomical variations have clinical implications for the location of unilateral SSFBs.

Objectives: To minimize the risk of V3 segment of vertebral artery (VA) injury in the atlantoaxial dislocation (AAD) patients with C1 pedicle height less than 4.0 mm and provide a strong toggle force in irreducible AAD and revision surgery. We evaluated the feasibility of C1 "Zero Angle" screw (C1ZAS) and safe entry point with "in-out-in" technique as an alternative option for C1 pedicle screw (PS) in cases with AAD.
