OBJECTIVE To evaluate the use of autogenous maxillary bone for the repair of orbital floor defects secondary to blunt facial trauma. DESIGN Retrospective case series of 41 patients with a mean follow-up of 1.7 years. SETTING Major metropolitan teaching hospital. PATIENTS Forty-one consecutive patients who underwent repair of orbital floor fractures with maxillary antral wall bone grafts. ...

Spontaneous enophthalmos unrelated to trauma or surgery is rare. The term 'silent sinus syndrome' has been used to describe this process where, in particular, there is an absence of any sino-nasal symptoms. The enophthalmos and hypoglobus that occurs in these subjects is caused by atelectasis of the maxillary antrum, which itself appears to be due to chronic maxillary hypoventilation. We report...

The Silent Sinus Syndrome (SSS) is a rare condition that causes facial asymmetry, unilateral enophthalmos and diplopia. It is thought to be secondary to chronic maxillary sinus atelectasis (CMA) with reabsorbed bone and subsequent displacement of the orbital floor. Such anatomic modifications occur over time, and therefore it is possible to encounter different stages of the same disease with or...

We present a case of silent sinus syndrome (SSS) who underwent unilateral surgical endoscopic maxillary meatotomy. Orbital floor reconstruction is delayed after follow up. Enophthalmos recovered 8 months after the surgery and radiologic findings improved. SSS is a clinical entity that should be kept in mind in the differential diagnosis of enophthalmos and can be treated successfully via endosc...

CLINICAL CASE A 53 year-old man presented with a progressive enophthalmos without any sinus or nasal symptoms. There was no history of a trauma. The ophthalmology examination showed enophtalmos and hypoglobus. The computerized tomography (CT) showed a collapsed maxillary and frontal sinus and a lateral deviation of the nasal septum that led us to the diagnosis. DISCUSSION The clinical feature...

Silent sinus syndrome (SSS) is a rare and interesting clinical condition that is associated with spontaneous, painless, unilateral enophthalmos and hypoglobus resulting from downward bowing of the orbital floor, in the absence of any symptomatic sinonasal disease. It generally affects younger patients between the third and fifth decades of life. The pathogenesis of silent sinus syndrome is base...

INTRODUCTION The frequently used irrigant in dental surgery, sodium hypochlorite, is occasionally the cause of minor, usually circumscribed, adverse effects. Severe, extensive complications, with lasting sequelae, however, also can occur, as in the case we report herein. CASE REPORT A 55-year-old woman underwent an endodontic procedure on a maxillary molar, whose roots, unknown to the surgeon...

Silent sinus syndrome (SSS) or chronic maxillary atelectasis (CMA) is characterized by enophthalmos or hypo Globus along with maxillary sinus atelectasis and lateralization of the uncinate process without classic rhino sinusitis symptoms. A previous description of surgical management includes maxillary antrostomy with orbital floor repair via an implant, possibly as a two-stage procedure. The o...

Although inferior alveolar nerve block is one of the most common procedures performed at dental clinics, complications or adverse effects can still occur. On rare occasions, ocular disturbances, such as diplopia, blurred vision, amaurosis, mydriasis, abnormal pupillary light reflex, retrobulbar pain, miosis, and enophthalmos, have also been reported after maxillary and mandibular anesthesia. Ge...

Silent Sinus Syndrome (SSS) is known to be a rare clinical condition, characterized by spontaneous and progressive enophthalmos and hypoglobus associated with atelectasis of the maxillary sinus and alteration of the orbital floor. Most of the patients with this syndrome present with ophthalmological complaints without any nasal sinus symptoms, and it typically has a painless course and slow dev...
