Cranial Bones: Lateral View

Cranial 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...

Summary

This summary is machine-generated.

A novel septal reconstruction technique using perpendicular plate of ethmoid (PPE) and septal cartilage effectively improves nasal ventilation and aesthetics in East Asian patients with unilateral cleft lip and nasal deformity (UCLND). Results show comparable aesthetic outcomes to traditional costal cartilage methods.

Background:

East Asian patients with unilateral cleft lip and nasal deformity (UCLND) often present with severe septal deviation.
Traditional septal reconstruction methods may not fully address functional and aesthetic concerns.

Purpose of the Study:

To evaluate an innovative septal reconstruction method using perpendicular plate of ethmoid (PPE) and septal cartilage.
To compare its efficacy with costal cartilage reconstruction for UCLND in East Asian patients.

Main Methods:

Retrospective study of 24 UCLND patients (1:1 ratio) comparing PPE and costal cartilage reconstruction.
Preoperative and postoperative NOSE and ROE scale assessments.
Computational fluid dynamics (CFD) analysis of nasal airway morphology and airflow in a PPE case.

Main Results:

Septal reconstruction with PPE significantly improved NOSE and ROE scores.
ROE score improvements were comparable to those achieved with costal cartilage.
CFD analysis demonstrated enhanced bilateral nasal airway morphology and improved airflow symmetry with PPE.

Conclusions:

Combined PPE and septal cartilage reconstruction is effective for improving nasal ventilation and symmetry in UCLND patients.
This technique offers aesthetic results similar to costal cartilage reconstruction, providing a viable alternative.
