Summary
Sigmoid sinus diverticula can cause severe pulsatile tinnitus (PT). Surgical decompression and recontouring of a sigmoid sinus diverticulum with hydroxyapatite bone cement effectively treated a patient with worsening unilateral PT.
Area of Science:
- Neurosurgery
- Vascular Surgery
- Otolaryngology
Background:
- Sigmoid sinus diverticula are rare venous anomalies.
- They often manifest as pulsatile tinnitus (PT).
- Severe PT may necessitate surgical intervention.
Purpose of the Study:
- To report a case of a patient with severe unilateral pulsatile tinnitus caused by a sigmoid sinus diverticulum.
- To describe the surgical management of this condition.
Main Methods:
- A 59-year-old female with worsening unilateral PT was evaluated.
- CT angiography revealed a 5 mm sigmoid sinus diverticulum.
- The diverticulum was surgically decompressed and recontoured using hydroxyapatite bone cement.
Main Results:
- The surgical intervention successfully treated the patient's severe pulsatile tinnitus.
- The use of hydroxyapatite bone cement facilitated the recontouring of the sigmoid sinus.
Conclusions:
- Surgical decompression and recontouring of sigmoid sinus diverticula are effective treatment options for severe pulsatile tinnitus.
- Hydroxyapatite bone cement is a viable material for sigmoid sinus recontouring.

265
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

01:18Sinusoidal Sources

Direct current (DC) refers to an electric current that flows in a single direction, maintaining a constant polarity. This is in contrast to alternating current (AC), which periodically changes its direction and magnitude. AC forms the backbone of modern electricity transmission and distribution systems due to its efficient long-distance transmission capabilities.

01:16ECG Interpretation of Arrhythmias I: Sinus Arrhythmias
436
Arrhythmias are disturbances in the heart's rhythm that lead to abnormal heartbeats. These irregularities can originate from different parts of the heart and are classified based on their origin and nature.
Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...

01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
67
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

01:15Heart Sounds
2.4K
Heart sounds are generated by the turbulence in blood flow due to the closing of heart valves. These sounds are best perceived slightly away from the valves, where the blood flow disseminates the sound.
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V)...

01:16Anatomy of the Ear
9.0K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
