  • one stage bone strip reconstruction technique with balloon sinus dilatation surgery for chronic maxillary atelectasis
    Clinical Ophthalmology, 2016
    Co-Authors: Tomoyuki Kashima, Robert A Goldberg, Jocelyne C Kohn, Daniel B Rootman
    Abstract:

    PURPOSE Chronic maxillary atelectasis is characterized by unilateral spontaneous enophthalmos and Hypoglobus due to increased orbital volume secondary to maxillary sinus inward deformation. Reformation of the sinus architecture and reconstruction of the orbit are key to a successful outcome. Here, we introduce a one-staged surgery that addresses both these goals. PATIENTS AND METHODS We retrospectively reviewed 11 patients treated with one-stage orbital and sinus surgery. A transconjunctival subperiosteal approach was used to create slats in the thinned orbital floor. A nasal endoscopic approach was utilized to access the maxillary sinus and place a modified Foley catheter balloon through the enlarged maxillary ostium. A bridge graft of nasal septal, ear cartilage, or LactSorb was placed on the reconstructed and balloon-supported orbital floor. The balloon was deflated and removed at 10-14 days. All patients underwent complete ophthalmic and orbital evaluation, including standardized photography and radiologic imaging. RESULTS Eleven patients, mean age 39.5 years, presented with diplopia in upgaze, superior sulcus deformity, and at least 2 mm of relative enophthalmos. After initial overcorrection, enophthalmos improved in all cases. Symmetry within 1 mm was accomplished in 10 of 11 cases. Follow-up time was 259±320 days. Full motility was recovered in all patients. CONCLUSION We describe a one-staged surgery consisting of cutting slats in the orbital floor, dilating the maxillary sinus with a balloon, and stabilizing the orbital floor with a cartilage graft placement. Our anecdotal experience suggests that this surgical approach can safely achieve normalization of the pathologic sinus outflow and restoration of the orbit anatomy. The balloon ensures orbital floor stability during the healing process, and it may act to stent open the sinus ostium during early mucosal healing.

  • the silent sinus syndrome maxillary sinus atelectasis with enophthalmos and Hypoglobus
    Current Opinion in Ophthalmology, 2004
    Co-Authors: Lawrence M Buono
    Abstract:

    Purpose of review The silent sinus syndrome is a rare clinical entity of spontaneous enophthalmos and Hypoglobus caused by an alteration of the normal orbital architecture and function from maxillary sinus collapse in the setting of chronic sinusitis. Recent findings The maxillary sinus collapse appears to result from the development of negative sinus pressure from an acquired obstruction of the maxillary sinus outflow. Patients most often present with symptoms relating to enophthalmos, although few report any symptoms of sinus disease. Summary Characteristic radiographic features of the maxillary sinus including opacification and collapse of the antral walls with inward bowing of the orbital floor are necessary for diagnosis.

  • single point fixation for noncomminuted zygomaticomaxillary complex fractures a 20 year experience
    Journal of Oral and Maxillofacial Surgery, 2020
    Co-Authors: Tom Shokri, Mofiyinfolu Sokoya, Jason E Cohn, Arash Bahrami, Jared C Inman, Yadranko Ducic
    Abstract:

    Abstract Purpose Zygomaticomaxillary complex (ZMC) fractures occur commonly, with no clinical consensus on number of fixation points required when performing open reduction and internal fixation. The goal of this study is to explore the utility of single point fixation in the management of non-comminuted zygomaticomaxillary complex (ZMC) fractures. Methods Retrospective case series of 211 patients over a 20-year period. Results Mean length of follow-up was 3.4 months. 162 patients with non-comminuted ZMC fractures were treated with single point fixation of the zygomaticomaxillary buttress. During the follow-up period, 1 patient experienced tooth loss due to a root in the fracture line. 7 patients experienced intraoral plate exposure, with 2 subsequently undergoing plate exchange. 8 patients experienced wound infection. No patients required orthognathic surgery or cheek implants for malar asymmetry. No patients developed Hypoglobus, enophthalmos and none required revision ORIF of their ZMC fractures. Conclusions This study represents the largest series in the literature reporting surgical results and outcomes of patients with non-comminuted ZMC fractures treated with single point fixation. In experienced hands, we believe this is a viable surgical option if appropriate surgical considerations are made.

    Abstract:

    Abstract Background We describe the surgical treatment of silent sinus syndrome, a disease characterized by progressive enophthalmos and Hypoglobus due to orbital floor collapse with opacification of the maxillary sinus, in the presence of chronic maxillary sinusitis. Methods Case study of a 55-year-old male with persistent diplopia secondary to left-sided esotropia and enophthalmos from chronic maxillary sinusitis. Results Two stage procedure to treat the sinonasal and orbital symptoms, which include endoscopic sinus surgery to treat the underlying the ostial obstruction along with decompression of maxillary sinus. Then, reconstruction of the orbital floor with a customized implant. Conclusions Though the treatment of silent sinus syndrome can be challenging, we demonstrate the successful use of a customized orbital implant in the treatment of diplopia and enophthalmos from silent sinus syndrome using a two-stage approach.

  • clinical features and treatment of late enophthalmos after orbital decompression a condition suggesting cause for idiopathic imploding antrum silent sinus syndrome
    Ophthalmology, 2003
    Co-Authors: Geoffrey E Rose, Valerie J Lund
    Abstract:

    Abstract Purpose To review the clinical and radiologic characteristics of a group of patients who experienced late enophthalmos after bone-removing orbital decompression. The surgical management of these patients is presented and a hypothesis proposed to explain the idiopathic "imploding antrum" ("silent sinus") syndrome. Design Retrospective, noncomparative case series. Participants Six patients experienced relative enophthalmos, Hypoglobus, and upper eyelid sulcus deformity at between 3 and 6 months after bone-removing orbital decompression for thyroid orbitopathy. Five left orbits and one right orbit were affected. Intervention All patients underwent middle meatal antrostomy, together with mobilization and elevation of the collapsed orbital contents by firm packing of the affected maxillary antrum through a buccal antrostomy, the pack being removed about 3 weeks after placement. Main outcome measures Symptomatic improvement and reduction in the degree of relative enophthalmos, Hypoglobus, and upper eyelid sulcus deformity. Results Late-onset enophthalmos after orbital decompression was associated with clinical and radiologic features that resemble the idiopathic imploding antrum syndrome. In all patients, the ethmoidal infundibulum was obstructed by prolapsed orbital fat with secondary antral consolidation, and inward bowing of the maxillary walls was present in five of six patients. After antral drainage and packing, there was an improvement in enophthalmos (mean, 2.7 mm; range, 0–4 mm) and all but one globe returned to within 2 mm of exophthalmometry of the contralateral eye. For recurrent enophthalmos in two patients (minor in one patient and marked in the other), later repair of the orbital floor was undertaken through a lower eyelid swinging flap, using porous polythene sheet, with good cosmetic outcome. Conclusions Late-onset enophthalmos after bone-removing orbital decompression seems to be the result of obstruction of maxillary antral aeration, with secondary fluid retention and a subatmospheric pressure in the sinus. This iatrogenic condition, associated in most cases with inward collapse of the maxillary walls, provides a guide to a hypothetical mechanism for the idiopathic imploding antrum (silent sinus) syndrome.

  • an unusual cause of oscillopsia
    British Journal of Ophthalmology, 2001
    Co-Authors: Hadi Zambarakji, Geoffrey E Rose
    Abstract:

    Editor,—Chronic maxillary atelectasis (CMA),1 also known as silent sinus syndrome (SSS)2 describes the same condition. Typically, the patient presents with acute enophthalmos and Hypoglobus in the absence of previous trauma or surgery. Past sinus disease may be present and computed tomograph (CT) scans demonstrate ipsilateral sinus contraction, orbital floor resorption, and thinning with inferior prolapse into the maxillary sinus. We present a patient who noted oscillopsia while jogging 1 year after being diagnosed with SSS. ### CASE REPORT A 26 year …
