Summary
Facial palsy is a rare complication following bilateral sagittal split ramus osteotomy (BSSRO). This case study highlights a patient
Area of Science:
- Oral and Maxillofacial Surgery
- Neurosurgery
- Orthognathic Surgery
Background:
- Bilateral sagittal split ramus osteotomy (BSSRO) is a common orthognathic surgical procedure.
- Neurological complications, such as altered sensation from the inferior alveolar nerve, are known sequelae of mandibular osteotomies.
- Peripheral facial palsy is an uncommon postoperative complication of BSSRO.
Observation:
- A 42-year-old male developed peripheral facial palsy one day after undergoing BSSRO for mandibular protrusion.
- The patient was treated with oral prednisolone, gradually tapered over time.
Findings:
- Complete recovery of right facial muscle movement was observed within one month.
- Full recovery without residual asymmetry was achieved after two months.
- Potential causes include retractor-induced facial nerve compression and postoperative edema.
Implications:
- Peripheral facial palsy is a rare but possible complication of BSSRO.
- This potential complication should be included in the informed consent process for patients undergoing BSSRO.
- Awareness of this complication is crucial for timely diagnosis and management.

01:24Facial Feedback Hypothesis

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...

01:14Muscles for Facial Expressions
4.8K
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...

01:13¹H NMR: Complex Splitting
1.8K
A proton M that is coupled to a proton X results in doublet signals for M. However, NMR-active nuclei can be simultaneously coupled to more than one nonequivalent nucleus. When M is coupled to a second proton A, such as in styrene oxide, each peak in the doublet is split into another doublet.
Splitting diagrams or splitting tree diagrams are routinely used to depict such complex couplings. While drawing splitting diagrams, the splitting with the larger coupling constant is usually applied...

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

An Incident or Occurrence Report in a healthcare setting is a crucial document used to record any unexpected occurrence that may or may not have affected a patient, employee, or visitor. Such reports are critical to improving patient safety and include all details leading up to and including the event.
