The Journal of Laryngology and Otology
|March 1, 1981
Summary
This study reviews 23 osteoma cases in the paranasal sinuses, detailing their causes, symptoms, and origins. It discusses treatment, natural progression, and surgical options, comparing findings with existing literature.
Area of Science:
- Otolaryngology
- Neurosurgery
- Oncology
Background:
- Osteomas are benign bone tumors.
- Paranasal sinus osteomas are relatively common.
- They can cause significant symptoms due to their location.
Purpose of the Study:
- To present a series of 23 paranasal sinus osteoma cases.
- To analyze the etiology, presentation, site of origin, and pathology.
- To discuss management, natural history, prognosis, and surgical approaches.
Main Methods:
- Retrospective case series review.
- Analysis of clinical data, imaging, and histopathology.
- Literature review and comparison with current series.
Main Results:
- Detailed presentation of 23 osteoma cases.
- Discussion of etiological factors and common sites of origin.
- Evaluation of various management strategies and surgical outcomes.
Conclusions:
- Osteomas of the paranasal sinuses require careful evaluation and tailored management.
- Surgical intervention is often necessary for symptomatic lesions.
- Understanding the natural history aids in prognosis and treatment planning.

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,...

01:27Cranial 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...

01:24Nose 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...
01:29Anatomy 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.

01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
