Summary
Maxillary sinus fungal balls are linked to concha bullosa and dental issues. Combinations of anatomical factors like concha bullosa and Haller cells may reduce fungal ball incidence.
Area of Science:
- Otolaryngology
- Medical Imaging
Background:
- Unilateral maxillary sinus fungal ball (MSFB) is a common condition.
- Understanding associated anatomical and dental factors is crucial for diagnosis and treatment.
Approach:
- CT scans of 300 patients were analyzed, categorizing them into MSFB, normal, and chronic rhinosinusitis (CRS) groups.
- Evaluated anatomical variations including deviated nasal septum, concha bullosa (CB), Haller cells, and dental factors.
- Measured ethmoid infundibulum, maxillary ostium, and CB dimensions.
Key Points:
- MSFB showed a significant association with concha bullosa (CB).
- Haller cells were less frequent in the MSFB group compared to the normal group.
- Wider maxillary sinus ostium and prevalence of dental factors were observed in the MSFB group.
Conclusions:
- Maxillary sinus fungal ball is significantly associated with anatomical variations like CB and Haller cells, larger maxillary ostium size, and dental factors.
- The combination of CB and Haller cells showed a decreased rate of fungal ball formation.
- Dental factors were notably more prevalent in both MSFB and CRS groups.

01:27Cranial Bones: Lateral View
3.5K
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...

01:14Cranial Bones: Superior and Posterior View
3.8K
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,...

01:08Overview of the Skull
6.3K
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...

01:29Anatomy of Respiratory System I: Upper Respiratory Tract
3.3K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.

01:24Nose and Nasal Cavity
6.3K
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...

01:22Sutures of the Skull
8.8K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
