Image-guided Temporal Bone Dissection Course.

 Temporal bone anatomy is complex and demands a profound anatomical knowledge. Association between surgery and imaging helps in the process of learning three-dimensional (3D) anatomy and surgical techniques. High definition temporal bone imaging can play an important role in dissection training.

Double-Needle Arthrocentesis with Viscosupplementation in Patients with Temporomandibular Joint Disc Displacement without Reduction.

Objectives: Arthrocentesis is the simplest surgical intervention for the temporomandibular joint (TMJ). It can be performed on an outpatient basis at a low cost and with low morbidity. The objective is to release the articular disc by disrupting the adhesion formed between its surfaces and the mandibular fossa through hydraulic pressure generated by irrigation of the upper compartment of the TMJ.

Comparison of two needles arthrocentesis versus double needle cannula arthrocentesis in the treatment of temporomandibular disc displacement.

Objective: To compare clinical and imaging results of two needles arthrocentesis (TNA) versus double-needle cannula arthrocentesis (DNCA) in the treatment of temporomandibular joint disc displacement (DD).

Methods: Twenty patients with DD were randomly divided into two groups: TNA and DNCA. Clinical data (pain scores; maximal interincisal distance [MID], and protrusion and laterality movements) were evaluated before and 24 months after the arthrocentesis.

The Role of Magnetic Resonance Imaging of the Temporomandibular Joint to Investigate Tinnitus in Adults with Temporomandibular Joint Disorder: A Comparative Study.

 The prevalence of tinnitus is higher in individuals with temporomandibular joint disorder (TMD) than in the general population. Magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) is the method of choice for investigation, and it has been hypothesized that specific MRI findings might be observed in TMD with comorbid tinnitus.  To comparatively describe MRI findings in patients with TMD with and without tinnitus, identifying the most common TMJ alterations and determining whether a correlation exists between severity of TMD and tinnitus.

Double puncture versus single puncture arthrocentesis for the management of unilateral temporomandibular joint disc displacement without reduction: A randomized controlled trial.

Purpose: To compare the clinical efficacy of the conventional double puncture versus single puncture type 2 arthrocentesis for management of temporomandibular joint disc displacement without reduction (DDWOR).

Materials And Methods: Twenty-six patients with DDWOR were randomly and blindly allocated into two treatment groups (N = 13): Group 1, conventional double puncture arthrocentesis; Group 2, single puncture type 2 arthrocentesis. Data on gender, side of painful joint complaint, age (years), duration of joint pain (months), maximum interincisal distance (MID - mm), and pain intensity self-reported with a visual analog scale (VAS; 0-10) were collected.

Evaluation of effusion and articular disc positioning after two different arthrocentesis techniques in patients with temporomandibular joint disc displacement without reduction.

Objective: To evaluate joint effusion and positioning of the articular disc through magnetic resonance imaging (MRI) before and after two different arthrocentesis techniques.

Methods: Twenty-six patients with dislocation of the articular disc without reduction (ADDwoR) were included and randomly divided into two groups: single needle arthrocentesis with distention of the upper compartment of the TMJ (A1) and conventional arthrocentesis with 2 needles (A2).

Results: A statistically significant difference was observed between the different effusion categories ( = 0.

Single-Needle Arthrocentesis with Upper Compartment Distension versus Conventional Two-Needle Arthrocentesis: Randomized Clinical Trial.

The objective of this study was to compare single-needle arthrocentesis with distension of the upper compartment of the temporomandibular joint (TMJ) with the conventional two-needle arthrocentesis. Twenty-six patients with articular disc displacement without reduction (DDWOR) were included in the study and assigned to two groups ( = 13): single-needle arthrocentesis with distension of the upper compartment of the TMJ (1N) and conventional two-needle arthrocentesis (2N). The maximum interincisal distance (MID) and TMJ pain as measured by the visual analog scale (VAS) were compared.

The Crista Fenestra and Its Impact on the Surgical Approach to the Scala Tympani during Cochlear Implantation.

Objective: The aim of this work was to describe the dimensions of the crista fenestra and determine its presence by means of high-resolution computed tomography (CT) for the purpose of cochlear implantation via the round window approach.

Methods: A series of 10 adult human temporal bones underwent high-resolution CT scanning and were further dissected for microscopic study of the round window niche.

Results: In all of the specimens, the round window membrane was fully visualized after the complete removal of bony overhangs.

Renal oxygen content is increased in healthy subjects after angiotensin-converting enzyme inhibition.

Objective: The association between renal hypoxia and the development of renal injury is well established. However, no adequate method currently exists to non-invasively measure functional changes in renal oxygenation in normal and injured patients.

Method: R2* quantification was performed using renal blood oxygen level-dependent properties.

Transcanal cochleostomy in cochlear implant surgery: long-term results of a cohort study.

Unlabelled: The combined approach technique (CAT) is a variation of the classical the mastoidectomy-posterior tympanotomy technique (MPTA) that combines a transcanal approach to cochleostomy with a reduced posterior tympanotomy for insertion of electrodes.

Aim: To compare and evaluate long-term safety and effectiveness outcomes obtained with the CAT and with MPTA approach in patients submitted to cochlear implant (CI) surgery.

Design: series study.
