Summary
A modified temporalis myoplasty using an extended lazy-S incision offers a scar-free alternative for smile reconstruction. This technique provides good functional outcomes for patients with facial paralysis.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Facial Nerve Surgery
Background:
- Lengthening temporalis myoplasty is a less invasive smile reconstruction technique.
- A standard approach requires a nasolabial fold incision, resulting in a facial scar.
- A modified technique using an extended lazy-S incision was developed to improve aesthetics.
Purpose of the Study:
- To evaluate the efficacy and safety of a modified lengthening temporalis myoplasty using an extended lazy-S incision.
- To assess aesthetic outcomes and functional results in patients undergoing this procedure.
Main Methods:
- A cadaveric study was performed on 10 hemifaces.
- The modified lengthening temporalis myoplasty was performed on 10 patients between 2013 and 2016.
- Outcomes were graded using the Terzis grading system, and oral commissure excursion was measured.
Main Results:
- The extended lazy-S incision provided safe and adequate surgical access.
- Patients (mean age 56.5 years) showed improved smile symmetry, with 2 excellent, 5 good, and 3 moderate results.
- Oral commissure excursion ranged from 5 to 10 mm, with one case of manageable surgical site infection.
Conclusions:
- The modified lengthening temporalis myoplasty with an extended lazy-S incision yields satisfactory functional results without significant complications.
- This approach avoids facial scarring, making it ideal for young, female, and parotid surgery patients.

01:14Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance
698
Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...

01:14Muscles for Facial Expressions
5.0K
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...

01:24Facial Feedback Hypothesis
686
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

01:31Formation of Species
45.5K
Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

01:26Personality Disorders: Narcissistic and Avoidant
859
Narcissistic and avoidant personality traits represent two contrasting patterns of behavior that significantly influence social interactions and self-perception. While individuals with narcissistic disorder seek admiration and validation, individuals with avoidant personality disorder withdraw due to fear of judgment.
Characteristics of Narcissistic Personality Disorder
Narcissistic individuals exhibit an inflated sense of self-importance and an excessive need for admiration. They are often...

01:14Avoidance Learning and Learned Helplessness
2.7K
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
