Summary
Computed Tomographic (C.T.) scanning of paranasal sinuses is crucial for preoperative planning in Functional Endoscopic Sinus Surgery. This study evaluated bony variations and mucosal abnormalities in chronic sinusitis patients to understand their role in surgical outcomes.
Area of Science:
- Otolaryngology
- Radiology
- Anatomy
Background:
- Coronal Computed Tomographic (C.T.) scanning is vital for preoperative assessment in Functional Endoscopic Sinus Surgery (FESS).
- Understanding anatomical variations and mucosal abnormalities is key to successful FESS outcomes.
- Chronic sinusitis often involves complex anatomical and pathological findings.
Purpose of the Study:
- To determine the prevalence of bony anatomical variations in paranasal sinuses.
- To identify and report mucosal abnormalities within the paranasal sinuses.
- To assess the potential pathogenicity of these findings in patients evaluated for FESS.
Main Methods:
- Coronal plane C.T. scans of the paranasal sinuses were performed on 61 patients with chronic sinusitis.
- The study investigated anatomical variations including Agger nasi cells, middle turbinate pneumatization, Heller's cells, paradoxical middle turbinate, deviated septum, and uncinate process variations.
- Mucosal abnormalities in each paranasal sinus were systematically reported.
Main Results:
- The study identified a range of bony anatomical variations and mucosal abnormalities in the paranasal sinuses of patients with chronic sinusitis.
- Specific variations like Agger nasi cells and middle turbinate pneumatization were noted.
- The prevalence and specific types of mucosal abnormalities were documented.
Conclusions:
- Preoperative C.T. scanning is essential for mapping paranasal sinus anatomy and identifying variations relevant to FESS.
- The findings provide baseline data on the prevalence of bony variations and mucosal abnormalities in chronic sinusitis patients.
- Further research may elucidate the direct impact of these findings on FESS outcomes and patient management.

01:27Cranial 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...

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

01:24Nose 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...
01:08Overview of the Skull
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
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.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.

01:22Sutures of the Skull
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...
