Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

2.0K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Epistaxis01:30

Epistaxis

118
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

    Area of Science:

    • Otolaryngology
    • Rhinology
    • Surgical Innovation

    Background:

    • The pyriform aperture is a critical nasal structure that can impede airflow.
    • Limited airflow through the pyriform aperture contributes to nasal obstruction in certain individuals.

    Observation:

    • A novel surgical technique was developed to access and modify the pyriform aperture.
    • Ultrasonic instrumentation was employed for precise surgical enlargement of the pyriform aperture.

    Findings:

    • Intraoperative measurements confirmed an average pyriform aperture width enlargement of 2.9 mm.
    • Nasal Obstruction Symptom Evaluation (NOSE) scores demonstrated a significant reduction, decreasing from 69.4 to 8.3 at 6 months post-surgery.

    Implications:

    • Open rhinoplasty provides a viable approach for pyriform aperture modification.
    • Enlarging the pyriform aperture offers a therapeutic solution for improving nasal obstruction and breathing.
