Clinical Trial Summary
The present study aims to compare ethmoid, sphenoid and maxillary sinus volumes of patients
with maxillary deficiency requiring Le Fort osteotomy with healthy patients, by employing
computed tomography imaging. No accessible information could be found on this subject during
literature search. The authors believe anatomical knowledge of these structures in patients
with maxillary deficiency will influence all branches performing surgeries in these areas.
Description:
The anatomy of the paranasal sinuses is important for many surgeon groups. The precise
knowledge of such structures with variable anatomy will be important for the preservation of
these structures and the management of complications in surgeries such as endoscopic sinus
surgery and osteotomies involving the maxilla such as Le Fort osteotomies. The
maxillomandibular complex is often affected by developmental problems and growth problems,
and unilateral, bilateral, horizontal, vertical and / or transverse deficiencies are
observed. Treatment of this complex is often performed by surgical intervention involving one
or both jaws. In surgeries involving the maxilla, maxillary sinuses are affected by the
surgery and affect the course of surgery. Paranasal sinuses are also very important
structures for closely related endoscopic sinus surgeries. Detailed preoperative
investigation is crucial for patient selection and hence desired outcome. Study was conducted
in Ankara University Faculty of Dentistry with Ethical approval number:08/03. Computed
tomography scans of 120 patients (59 maxillary deficiency patients and 61 healthy controls)
were included in the study. CT scan indications for the group with maxillary deficiency was
surgical preparation for Le Fort I osteotomy. The control group had no maxillary deficiency
and CT images were obtained for several reasons such as temporomandibular disease,
preparation for orthodontic treatment, obstructive sleep apnea and also paranasal sinus
imaging Patients with a history of trauma in the midline skull base were excluded.
Statistically significant results were obtained between groups for ethmoid and maxillary
sinus volumes (left and right). Ethmoid and maxillary sinus volumes (left and right) were
smaller in the Le Fort group. No statistically significant differences were present for
sphenoid sinus volume of two groups and for the left and right maxillary sinus volumes in
both groups.
