Summary
Maxillary sinus septa, bony barriers within the sinus, are present in 13-35.3% of individuals. Awareness of these septa is crucial for surgical procedures like sinus lifts to prevent complications.
Area of Science:
- Anatomy
- Oral and Maxillofacial Surgery
- Radiology
Background:
- Maxillary sinus septa are bony formations within the maxillary sinus.
- They can be primary (developmental) or secondary (acquired after tooth loss).
- Their presence impacts surgical procedures like sinus lifts.
Purpose of the Study:
- To review existing literature on the prevalence and characteristics of maxillary sinus septa.
- To highlight the clinical significance of septa in sinus augmentation procedures.
Main Methods:
- Systematic literature search on PubMed using relevant keywords.
- Analysis of 11 selected articles assessing maxillary sinus septa.
- Review of various detection methods including direct observation and radiographic imaging (panoramic radiographs, CT scans).
Main Results:
- Maxillary sinuses exhibit septa in 13% to 35.3% of cases.
- Septa vary in size (2.5–12.7 mm mean length) and location within the sinus.
- Higher prevalence of septa may be associated with atrophic, edentulous areas.
Conclusions:
- Maxillary sinus septa are common anatomical variations.
- Surgeons must consider septa during sinus lift planning to avoid intraoperative complications.
- Modified surgical approaches may be necessary when septa are present.

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...
