Abstract

Insights

Anatomical variations in the paranasal sinuses, particularly a concha bullosa and a narrow, elongated infundibulum, are linked to maxillary sinus fungal balls (MSFB). These findings suggest a role for sinus anatomy in MSFB development.

Area of Science:

  • Otolaryngology
  • Medical Imaging
  • Anatomy

Background:

  • The exact cause of maxillary sinus fungal balls (MSFB) is unknown.
  • Poor sinus ventilation, influenced by paranasal sinus anatomical variations, is a potential factor in MSFB development.

Purpose of the Study:

  • To investigate the association between sinonasal anatomical variations and the development of MSFB.

Main Methods:

  • Computed tomography (CT) scans of 31 MSFB patients and 28 controls were analyzed.
  • Evaluated presence of Haller cells, concha bullosa, septal deviation angle, and infundibular dimensions.

Main Results:

  • Concha bullosa was significantly more frequent in MSFB patients (61.3% vs. 28.6%, p=0.006).
  • MSFB patients exhibited narrower (3.23±0.69mm vs. 3.99±1.17mm, p<0.001) and longer infundibula (9.71±1.43mm vs. 8.23±1.72mm, p<0.001).

Conclusions:

  • Sinonasal anatomical variations, including concha bullosa and narrow, elongated infundibula, may contribute to MSFB formation.
  • These anatomical factors could predispose individuals to MSFB development.

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

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...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

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...

Anatomy of Respiratory System I: Upper Respiratory Tract01:29

Anatomy of Respiratory System I: Upper Respiratory Tract

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.

Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.
