Frontal and Maxillary Sinus Pneumosinus Dilatans

AbstractBackground:Pathological paranasal sinus expansion secondary to air is uncommon. However, this condition may be symptomatic or cosmetically apparent, requiring surgical intervention. Various terms have been used to describe this condition, and nomenclature is controversial.Method:An 18-year-old man presented with right facial pain, and was subsequently found to have pneumosinus dilatans of the maxillary sinus. A search was conducted of the PubMed, Medline and Embase databases, using the key words ‘pneumosinus dilatans’, ‘pneumoc(o)ele’, ‘pneumatoc(o)ele’ and ‘maxillary sinus’. Articles were also hand-searched. Relevant articles published in English were reviewed.Results:The literature review identified 36 cases involving the maxillary sinus (including the present case), with 19 cases reported as pneumosinus dilatans, 12 as pneumocoeles, two as pneumatocoeles, two as pneumosinus dilatans multiplex and one as an air cyst. However, based on the strict classification described by Urken et al., the majority of these cases should be reclassified as pneumocoeles.Conclusion:Whilst the nomenclature of this pathology is confusing, distinctions of terminology do not alter the management. Hence, we support the use of the term ‘air cyst’, to incorporate all these lesions.

AbstractObjective:To report a patient with maxillary pneumosinus dilatans and facial deformity treated by reduction osteoplasty and reconstruction.Case report:This study describes the successful management of facial deformity in a 17-year-old male with maxillary pneumosinus dilatans. The patient's facial deformity of the maxillary sinus, which had been slowly progressing over a 10-year period, was managed by reduction osteoplasty and reconstruction using the maxillary bone, conchal cartilage and Tutoplast-processed fascia lata via a sublabial approach. This treatment yielded satisfactory functional and aesthetic outcomes.Conclusion:As pneumosinus dilatans of the maxillary sinus is uncommon, there is no established surgical treatment protocol. This surgical technique was less invasive than other described procedures and revealed good cosmetic results.

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.

Rare Differential Diagnosis

A case of the rare condition Pneumosinus dilatans of the maxillary sinus is presented. This is a rare differential diagnosis of a maxillary disease. The diagnostic imaging features of this condition are described, and a recommendation of views for adequately delineating this disorder is given. Only a few cases of Pneumosinus dilatans of the maxillary sinus are described in the English-language literature, and the precise cause and pathogenesis remain obscure. We performed an enlargement of the maxillary ostium in order to increase the ventilation of the paranasal sinus. In the short-term follow-up, this patient has been asymptomatic. The postulated mechanism of air trapping in the sinus cavity seems to be logical in this case, because the symptoms were eliminated by surgically decompressing the sinus to overcome this valve mechanism.

Entrapped Air

AbstractA cystic dilatation of a paranasal sinus by an entrapped air mass has beentermed pneumosinus dilatans or a pneumocoele. The occurrence of this condition in the maxillary sinus is quite rare. In the present case, a mid-face mass mimicking an osteoma was the presenting sign of the disease. The pathogenesis, clinical features and radiological aspects of this entity are reviewed. In order to avoid confusion with other conditions ofdifferent aetiopathogenesis, we propose to label the lesion as ‘air cyst’ of the paranasal sinus, a term that best describes the nature of the lesion.
