Understanding individual variations in maxillary sinus microanatomy is crucial for advancing endonasal endoscopic microsurgery. This knowledge optimizes surgical outcomes and patient safety.
Area of Science:
- Otolaryngology
- Surgical Anatomy
Background:
- Individual variations in paranasal sinus microanatomy are key to advancing endonasal endoscopic microsurgery.
- Maxillary sinus microanatomy is a significant area of ongoing scientific research.
Purpose of the Study:
- To present a comprehensive review of maxillary sinus microanatomy.
- To provide insights relevant to contemporary endonasal endoscopic microsurgery.
Main Methods:
- Comprehensive literature review focused on maxillary sinus microanatomy.
- Analysis from the perspective of endonasal endoscopic microsurgery.
Main Results:
- Detailed presentation of the range of individual microanatomical variations within the maxillary sinus.
- Identification of variations to minimize surgical trauma and prevent complications, such as orbital tissue damage.
- Establishment of a basis for prelacrimal access to the maxillary sinus.
Conclusions:
- Enhanced understanding of microanatomical variations improves surgical effectiveness.
- Knowledge of variations reduces patient burden and optimizes surgical procedures.

Cranial Bones: Lateral View
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...
