Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

2.7K
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...

Tooth Anatomy

1.1K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Overview of the Skull

5.4K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

Teeth01:15

Teeth

731
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

2.9K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

4.9K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Summary

This study details a rare giant complex odontoma within the maxillary sinus, unrelated to the alveolar process. The tumor was surgically excised using the Caldwell-Luc procedure and the defect repaired with titanium mesh.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Otorhinolaryngology
  • Pathology of Odontogenic Tumors

Background:

  • Complex odontomas are rare benign odontogenic tumors.
  • Previous cases in the maxillary sinus were associated with the alveolar process.
  • Giant complex odontomas entirely within the sinus are exceptionally rare.

Purpose of the Study:

  • To report a unique case of a giant complex odontoma.
  • To describe its presentation entirely within the maxillary sinus.
  • To document the surgical management and outcome.

Main Methods:

  • A rare case of giant complex odontoma was identified.
  • Surgical excision was performed via the Caldwell-Luc operation.
  • General anesthesia was utilized, and the bony defect was reconstructed with titanium mesh.

Main Results:

  • A giant complex odontoma was successfully removed from the maxillary sinus.
  • The lesion was completely intra-sinus and unassociated with the alveolar process.
  • Post-operative recovery was uneventful with successful defect closure.

Conclusions:

  • Giant complex odontomas can arise independently within the maxillary sinus.
  • The Caldwell-Luc operation is an effective surgical approach for such lesions.
  • Titanium mesh provides a viable option for bony defect reconstruction.
