Spontaneous maxillary sinus rupture in the absence of pre-existing sinus disease: case report

Subcutaneous Emphysema of the Orbit after Nose-Blowing

Orbital emphysema after nose-blowing is an uncommon condition and can appear without a trigger. Herein, we reported a case of orbital emphysema after nose-blowing and performed a literature review. A 68-year-old man fell and sustained an injury near his left orbit. No symptoms were noted. He noticed a left periorbital swelling after blowing his nose. Through computed tomography examination, he was diagnosed with subcutaneous emphysema. There are no previous reports that have reviewed the clinical features, need for surgery, and severity of symptoms of subcutaneous emphysema after nasal swallowing due to different factors. We retrospectively analyzed a cohort of 48 cases by searching PubMed to clarify these issues. Regarding the emphysema trigger, 21 cases had an injury or had previously undergone surgery. In 34 cases, conservative treatment was required, while surgery was selected in the acute phase in 6 cases and after the acute phase as a radical cure in 8 cases. Reduced visual acuity, diplopia, exophthalmos, facial hypoesthesia, and color disorders were noted and were more common among surgical cases. The literature review revealed no association between fracture location and the need for surgery; furthermore, surgery was less required in non-trauma cases, excluding osteoma, than in trauma cases (p = 0.0169). Our study reveals that a strict follow-up examination of visual symptoms is necessary for the first 2 days in cases of subcutaneous emphysema caused by nose blowing after facial trauma.

Spontaneous Fracture of the Maxillary Sinus as a Consequence of Nose-Blowing

ABSTRACT

Spontaneous fracture of the maxillary sinus without preceding trauma or pathology is extremely rare. Our patient presented with a maxillary sinus fracture related to recurrent nose-blowing, in the absence of any other cause. Although rare, spontaneous fracture of maxillary sinus should be considered in the differential diagnosis of pain and swelling of the cheek and eye in elderly patients.
