“…However, although a nasoantral window may relieve symptoms (if present), deformities may still persist. 14,20,32 Hyun et al 14 reported good cosmetic results after reduction osteoplasty. Antral wall turnover, greenstick downward fracture, and electrical burring were proposed by Choi et al 16 to correct facial deformities based on the thickness of the antral wall and the extension of the expanded area.…”

Background:Pneumosinus dilatans (PSD) is a rare pathological paranasal sinus expansion. This condition is usually symptomatic or cosmetically apparent, requiring surgical intervention. Multiple hypotheses have been postulated as to the cause of this condition; however, the precise cause and pathogenesis remain obscure.Case report and Methods:An 11-year-old boy presented with right eye bulging and was subsequently found to have PSD of the maxillary sinus. A search was conducted of the PubMed electronic database, using the keywords “pneumosinus dilatans,” “pneum(oco)ele,” “pneum(oc)ele,” “pneum(atoco)ele,” and “air cyst.” Articles published in English were reviewed.Results:The literature review identified 29 cases of PSD involving the maxillary sinus. The mean age of presentation was 25 years old. Only the right maxillary sinus was affected in 16 cases, followed by the bilateral sinuses in 7 cases and the left sinus in 6 cases. In 5 cases, all paranasal sinuses, along with the maxillary sinus, were expanded. The most common presenting symptom was facial swelling, which was found in 55% of the cases, followed by proptosis and pain. Computed tomography is the gold standard radiological method for diagnosing PSD.Conclusions:Pneumosinus dilatans is a rare condition that is usually symptomatic and requires surgical intervention. The etiology of the disease is attributed to multiple hypotheses, but more studies are needed to explore this condition further.

“…Viehweg et al described using an iliac bone graft and a bilateral sagittal split osteotomy for treating bilateral maxillary pneumosinus dilatans. 7 Breidahl et al reported two maxillary pneumosinus dilatans cases treated with direct resection of the primary lesion and reconstruction using a reversed cystic wall and medial maxillary wall via an intraoral approach. 8 • Pneumosinus dilatans presents as an abnormal, air-filled dilatation of the paranasal sinuses with intact mucosa and bony wall • Pneumosinus dilatans of the maxillary sinus is benign, but can lead to cosmetic deformity in the midface • As the condition is rare, there is no established surgical treatment protocol • In this case report, reduction osteoplasty resulted in a good cosmetic outcome…”

“…Three of the four cases demonstrated profiling of dental roots and displacement of the orbital floor. In our literature review, 12 cases showed thinning of the sinus wall, most commonly the anterior and orbital wall 5 , 10 , 13 , 16 – 18 , 20 , 21 , 23 , 25 , 32 , 34 . Only one case described bone thickening instead of thinning 14 …”
