Summary
Expanded forehead flaps used in nasal reconstruction contract significantly after harvest. This study quantifies flap contraction rates, providing crucial data for improved surgical design and patient outcomes.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Anatomy
Background:
- Flap contraction post-harvest complicates surgical design in nasal reconstruction.
- Understanding immediate flap dimensional changes is critical for successful outcomes.
Purpose of the Study:
- To investigate and quantify the immediate contraction rate of expanded forehead flaps utilized in nasal reconstruction.
- To provide objective data to aid surgeons in designing expanded forehead flaps.
Main Methods:
- Prospective study of 14 patients undergoing nasal reconstruction with expanded forehead flaps (Sept 2021 - Jan 2023).
- Objective measurements of pedicle width, maximum width, maximum length, and flap size were recorded before and after harvest.
Main Results:
- The average flap size reduction after harvest was 50.89%.
- Significant contraction rates were observed across pedicle width (16.15%), maximum width (30.26%), and maximum length (26.86%).
Conclusions:
- Expanded forehead flaps exhibit substantial immediate contraction post-harvest, averaging over 50% in size.
- Quantified contraction data is essential for optimizing expanded forehead flap design in nasal reconstruction procedures.

01:14Muscles for Facial Expressions
2.2K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

01:21Association Areas of the Cortex
5.5K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

01:28Angle Closure Glaucoma: Treatment
560
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

01:19Muscles that Move the Head
2.0K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
