Summary
Maxillary sinus septa, bony walls within the sinus, are common and can complicate dental implant surgery. Preoperative CT or CBCT scans are recommended for accurate diagnosis and surgical planning.
Area of Science:
- Dental Implantology
- Oral and Maxillofacial Surgery
- Radiology
Background:
- Maxillary sinus septa are anatomical variations that can complicate sinus elevation procedures.
- Undiagnosed septa pose a risk during sinus graft and dental implant surgeries.
- Understanding septa's prevalence and characteristics is crucial for surgical planning.
Purpose of the Study:
- To review published data on maxillary sinus septa.
- To analyze the etiology, prevalence, localization, and size of these septa.
- To determine optimal preoperative radiological examinations for diagnosis.
Main Methods:
- Systematic literature search of Medline (1980-2009).
- Keywords included "maxillary sinus anatomy," "maxillary sinus augmentation," and "maxillary sinus septa."
- Analysis of 22 relevant English-language studies.
Main Results:
- Prevalence of maxillary sinus septa varied between 14.3% and 33.3%.
- No specific geographic distribution was observed within the sinuses.
- Mean septa height ranged from 2.8 to 8.1 mm.
Conclusions:
- Maxillary sinus septa are prevalent and exhibit variable anatomy.
- Conventional X-rays have limited diagnostic value.
- Preoperative CT or CBCT scans are recommended for accurate diagnosis and surgical planning.

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.

01:27Cranial 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...
01:19Cranial and Spinal Meninges
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

01:18Anatomy of the Brain: Ventricles
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
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,...
