Previously, the treatment of maxillary sinus mucoceles was based on Caldwell-Luc sinusectomy, with the creation of a nasoantral window through the inferior meatus and a complete removal of the maxillary sinus lining to avoid recurrence.
Patients having any pathology in maxillary sinus like tumors or maxillofacial trauma or requiring prophylactic extraction before radiotherapy were excluded from the study.
Therefore, this study aimed to illustrate and classify the morphology of the maxillary sinus from 1 to 25 years of age focusing on the shape, septa and scalloping of the sinus according to sex and population groups.
Patients excluded from the study were patients with uncontrolled systemic diseases, ongoing chemotherapy, radiation therapy or maxillary sinus disease, immuno-compromised patients.
These include diminished sinus volume with retraction and inward bowing of the maxillary sinus walls, downward bowing and thinning of the orbital floor and increased orbital volume, near-to-complete sinus opacification, lateral retraction of the uncinate process with apposition of the uncinate against the inferomedial orbital wall, enlargement of the middle meatus and an increased retroantral fat pad (Figure 2).
Intranasal endoscopic prelacrimal recess approach to maxillary sinus.
Prevention of antrochoanal polyp recurrence was enabled by endoscopy of the nose and maxillary sinus.
Results: The epithelial tissues in the maxillary sinus mucosa of Group B were covered with multiple rows of cilia.
The location of principle ostium of the maxillary sinus is on the highest part of medial wall of maxillary sinus and is therefore responsible for poor free drainage.
4 CG can be seen in various areas of the body - especially within the mastoid antrum and air cells within the temporal bone - and mainly associated with chronic middle ear diseases, however it is extremely rare in paranasal sinuses and almost 40 cases of maxillary sinus CG have been reported.
