Summary
This study defines the deep pyriform space, an anatomical area in the midface. Understanding its aging changes and safe injection points is crucial for facial rejuvenation procedures.
Area of Science:
- Anatomy
- Facial Surgery
- Aging Face
Background:
- The Ristow space, now termed the deep pyriform space, is an anatomical region in the midface.
- Its anatomical boundaries, age-related changes, and clinical significance require definition.
Purpose of the Study:
- To define the anatomical boundaries of the deep pyriform space.
- To understand its transformation in the aging face.
- To elucidate its clinical implications, particularly for facial volumization.
Main Methods:
- Dissection of the deep pyriform space in 12 hemifacial cadavers.
- Measurement of dimensions and creation of plaster molds for shape analysis.
- Percutaneous injection of hyaluronic acid and pneumatization to assess adjacent structures and cephalic extension.
Main Results:
- The deep pyriform space averages 1.1 × 0.9 cm.
- It is bordered by the depressor septi nasi medially and deep medial cheek fat laterally.
- The angular artery is located superficially within a septum, allowing safe deep injections.
Conclusions:
- The deep pyriform space is a midface cavity relevant for age-related volume loss.
- It serves as a potential site for deep volumization to support facial structures.
- The anatomical position of the angular artery permits safe bone-surface injections.

01:26Muscles of the Pelvic Floor and Perineum
5.6K
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

01:25Assessment of the Rectum and Anus
1.7K
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

01:19Anatomy of the Genitourinary System II: Bladder and Urethra
2.4K
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

01:14Directional Terms
17.8K
Directional terms are essential for describing the relative locations of different body structures. For instance, an anatomist might describe one band of tissue as "inferior to" another, or a physician might describe a tumor as "superficial to" a deeper body structure. These terms often use comparative terms in pairs to trace out the relative locations of one body part to another or descriptions of body tissues like the deeper ones from superficially present with reference to...

01:23Urinary Bladder
4.1K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

01:19Abdominal Regions and Quadrants
19.2K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...
