Pneumosinus dilatans frontalis: two case reports

CT measurement of the frontal sinus – Gender differences and implications for frontal cranioplasty

“…The key limiting factor in this is the location of the frontal sinus, which can restrict the extent of frontal bone reduction and thus necessitate more extensive and invasive surgery. In these patients, it may be required that the frontal sinus be penetrated and the entire anterior sinus wall and associated supraorbital rim set back into its new, more feminine position (Ousterhout, 1987;Dempf et al, 2005).…”

“…As an example, pneumosinus dilatans, a rare craniofacial malformation marked by enlargement of the paranasal sinuses, often presents with primarily cosmetic complaints (Dempf et al, 2005). In such patients, selective reduction of the frontal sinus may be desirable in order to address the exaggerating frontal bossing which accompanies this condition.…”

Beyond aesthetics: A case report of pneumosinus dilatans frontalis presenting with headache

“…Several therapeutic strategies have been suggested for the treatment of PSD-related craniofacial bone deformities, and myriad open procedures have been documented: remodeling and repair of the frontal bulge with alloplastic material with a high incidence of local complications; reduction of the anterior wall of the frontal sinus without obliteration of the sinus cavity with undesirable aesthetic consequences; removing the front wall of the frontal sinus, inverting it, and filling the resulted cavity with bone dust from the parietal region with the creation of an extra donor site; removing the anterior wall of the frontal sinus and replacing it with bone attached with mini plates or a titanium mesh plate ( 12 , 13 , 19 ). The most popular craniofacial reconstruction open surgery technique for individuals with frontal sinus involvement is a bi-coronal incision with osteotomy bone resurfacing of the outer table of the frontal bone ( 20 ).…”

Pneumosinus dilitans and meningioma: a case series and review of the literature

“…4 The term "pneumosinus dilatans" was introduced by Benjamin in 1918. 3,6 In PSD there is enlargement of the paranasal sinuses, with expansion of the surrounding bone, without bony thinning or evidence of mucosal abnormality.…”
