AI Article Synopsis
- The study explores a new surgical method, Contralateral Inclinatory Approach using Unilateral Biportal Endoscopy (CIA-UBE), to address lumbar stenosis.
- Ten patients underwent this minimally invasive procedure, showing significant improvements in spinal canal measurements and pain relief post-surgery.
- Results suggest that CIA-UBE effectively decompressed nerves with less damage to surrounding structures, indicating its potential as a reliable treatment option.
Article Abstract
Objective: Unilateral biportal endoscopic (UBE)surgery is being increasingly adopted as a minimally invasive technique. The purpose of the current study was to introduce a novel surgical technique for lateral recess and same-level foraminal decompression by the contralateral inclinatory approach with unilateral biportal endoscopy(CIA-UBE) at the lumbar level.
Methods: Between January 2020 and February 2022, 10 patients suffering from lateral recess and same-level foraminal stenosis at the lumbar level underwent UBE surgery by contralateral inclinatory approach (CIA-UBE). Magnetic resonance imaging (MRI) scans were examined after surgery to measure the cross-sectional area (CSA) of the spinal canal (CSA-SC), the CSA of the intervertebral foramen (CSA-IVF), and the CSA of the facet joint (CSA-FJ). Postoperative radiologic images using computed tomography (CT) were obtained to investigate the existence of facet joint violation. Clinical outcomes were assessed using Oswestry Disability Index (ODI) scores and visual analogue scale (VAS) scores for buttock and radicular pain.
Results: Ten levels were decompressed, and the mean age of the patients was 56.92 ± 13.26 years. The mean follow-up period was 7.60 ± 4.47 months. The average operative time was 85.14 ± 25.65 min. Postoperative CT and MRI revealed ideal neural decompression of the treated segments in all patients. CSA-IVF and CSA-FJ improved significantly, indicating good foraminal and lateral recess decompression with less damage to facet joints. Preoperative VAS and ODI scores improved significantly after surgery.
Conclusion: CIA-UBE may be an effective surgical treatment of the lateral recess and same-level foraminal stenosis at the lumbar level, which provides successful surgical decompression for traversing and exiting nerve roots with a better operative view and easier surgical manipulation. This approach may also help to maximize the preservation of the facet joint.

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.

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.

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.

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.
