Aplasia of the Maxillary Sinus, a Large Periapical Cyst in the Maxillary Arch, and a Swimming ‎and Kissing Molar: A Rare Case Report

Abstract

Aplasia of the maxillary sinus and hypoplasia are rare conditions that can trigger symptoms such as headaches and altered speech. Most patients are asymptomatic, but given the role of these symptoms in the differential diagnoses for neoplasms and infection, such symptoms warrant investigating. We present a rare case of a young man with hypoplasia of the maxillary sinus on the left side with a large periapical cyst on the right side, diagnosed via a routine conebeam computed tomography (CBCT). This case discusses the role of CBCT in investigating aplasia of the maxillary sinus.

Retrospective CBCT analysis of maxillary sinus pathology prevalence in the Saudi Arabian population

“…Maxillary sinus pathology and its relationship with odontogenic infections are topics of significant concern in dentistry ( Hameed et al, 2021 ). The maxillary sinus is an air-filled cavity located within the maxillary bone of the human skull and is one of four paired paranasal sinuses along with the others being the frontal, ethmoid, and sphenoid sinuses ( Alnafisah et al, 2020 ). Maxillary sinus pathologies encompass a range of conditions that affect the sinus, including odontogenic maxillary sinusitis, mucous retention cysts (MRC), retention cysts (RC), and antral pseudocysts, which may or may not be associated with dental and periodontal infections, thickening of the sinus membrane (TSM), and radiological opacities ( Whyte and Boeddinghaus, 2019 ).…”

Clinical Features of Oroantral Communication Management Using Buccal Fat Pad by Tunnel Method

“…The oroantral communication (OCA), an open connection between the oral cavity and the maxillary sinus (MS), can occur during maxillary tooth extraction. The main risk factors are clinical, defined on radiographs as areas of periapical inflammation, and anatomical, representing the proximity of the roots of maxillary teeth or their penetration into the MS. 1,2 Most often, OAC occurs intraoperatively during extraction of maxillary molars and premolars 3 . There are many surgical techniques for management of OAC, which can be divided into several groups depending on the type of material used (autogenous, allogeneic, or xenogeneic).…”
