Purpose: This study aimed to introduce a new high-frequency ultrasound classification of De Quervain tenosynovitis based on a large group of patients. Detailed characteristics of classification are also reported.
Methods: From January 2014 to February 2024, patients diagnosed with De Quervain tenosynovitis were retrospectively reviewed. High-frequency ultrasound (7-14 MHz) scanning was performed to identify the anatomy of the extensor pollicis brevis and abductor pollicis longus tendons, presence of intertendinous septa, and pathologic changes. The affected wrist was compared to the contralateral wrist.
Results: 453 patients were included: 65 male and 388 female; mean age, 46 ± 27 years (range, 24-65 years). Symptom duration was 14 ± 27 weeks. Disease types were type 0 (n = 5), type 1 (n = 195), type 2a (n = 72), type 2b (n = 18), type 2c (n = 50), type 3 (n = 59), type 4 (n = 45), and type 5 (n = 9). Mean retinacular thickness was 2.1 ± 0.5 mm in affected wrists and 0.4 ± 0.1 mm in contralateral wrists (p < 0.01). The intercompartmental septum was significantly thicker on the affected side (1.2 ± 0.7 mm) than on the asymptomatic side (0.1 ± 0.4 mm) (p < 0.01).
Conclusions: This novel classification provides detailed ultrasonographic characteristics of De Quervain tenosynovitis, based on a large population of patients. It may help in selecting treatment and predicting outcome. However, relevance and therapeutic significance remain to be demonstrated.
Level Of Evidence: Therapeutic study, Level IV.

The most common transducers used to generate ultrasound in medical applications are based on short electrical pulses applied to piezoelectric transducers and capacitive micromachined ultrasound transducers. However, piezoelectric transducers have a limited frequency bandwidth, defined by their physical thickness, and capacitive micromachined ultrasound transducers have poor transmission efficiency. The high frequency cutoff limits the spatial resolution of ultrasonic images.

Introduction: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease affecting hair follicles, causing recurrent abscesses and nodules in intertriginous regions. The International HS Severity Score System (IHS4) is widely used to assess HS severity by counting inflammatory nodules, abscesses, and draining fistulas/tunnels. However, traditional clinical examinations may underestimate HS severity due to the presence of subclinical lesions.

Background: At present, the main clinical application of local ablation therapy, such as radiofrequency ablation (RFA), is to heat the tissue to a certain temperature. However, high temperature will cause thermal damage. Irreversible electroporation (IRE) is a novel minimally invasive local ablation technology for tumors.

This CME article explores the evolving role of endosonography in otorhinolaryngology and head and neck surgery. Endosonography offers significant potential to improve imaging inside the upper respiratory tract, particularly with advancements in probe technology and imaging resolution. The article will describe the sonoanatomy of the oral cavity, pharynx, and larynx and the selection of probes and scanning techniques used for the various anatomical sites.
