Single-step Functional Sinus Endoscopy and Transoral Surgery

The OMS is a well-known but understudied kind of sinusitis that necessitates a treatment regimen different from non-odontogenic sinusitis. It requires specialized attention because it differs in its pathophysiology, microbiology, diagnosis, and therapy than other forms of non-odontogenic sinusitis. There are several surgical techniques have been published to treat odontogenic maxillary sinusitis, such as transoral, transnasal endoscopic, or combined techniques. Multiple specialists are daily facing patients with maxillary sinusitis either odontogenic or non-odontogenic, including otolaryngologist, maxillofacial/oral, and dental surgeons.

The direct transoral method, which involves making a bone window in the anterolateral maxillary wall, is more familiar to maxillofacial/oral surgeons, whereas the transnasal endoscopic approach is gaining favor, particularly among otolaryngologists. There is no unanimity among clinicians on how and who should treat OMS, whether it is otolaryngologist, maxillofacial, or oral surgeon. This is one of the reasons why the results are frequently challenged as reported by others. Therefore, this study will be will be enrolled to evaluate the efficacy of the Single-step Functional Sinus endoscopy and trans-oral surgery in the management of maxillary sinusitis raised from Odontogenic origin via Department- integrated therapy.
