Chronic maxillary atelectasis and silent sinus syndrome: two faces of the same clinical entity.

Chronic maxillary atelectasis (CMA) and silent sinus syndrome (SSS) are rare clinical entities characterized by an implosion of the maxillary sinus that may or may not be associated with sinonasal symptoms, and are complicated by ipsilateral enophthalmos. The objective of this article is to discuss the definitions, physiopathology, clinical and radiographic characteristics, and surgical management of these entities. We retrospectively reviewed 18 patients (7 women, 11 men, aged 12-70 years) diagnosed and treated in the ear, nose, and throat departments of four Belgian teaching hospitals between 2000 and 2015. Nine patients had a history of sinus disease. In all cases, a computed tomography scan showed downward displacement of the orbital floor, increased orbital volume, and maxillary sinus contraction. Five patients met the criteria for grade II CMA and 13 for grade III CMA. Four patients met the criteria for SSS. All patients underwent wide endoscopic middle maxillary antrostomy. There were no orbital complications and all patients experienced resolution or a dramatic reduction of their symptomatology. Only one patient asked for an orbital floor reconstruction to correct a persisting cosmetic deformity. Although CMA and SSS are usually regarded as different entities in the literature, we believe that they lie on the same clinical spectrum. Treatment for both conditions is similar, i.e., middle meatal antrostomy to halt or even reverse the pathological evolution and reconstruction of the orbital floor in the event of persistent cosmetic deformity.

Are bovine pericardium underlay xenograft and butterfly inlay autograft efficient for transcanal tympanoplasty?

To evaluate the success rate and the surgical procedure of two different transcanal myringoplasty techniques using the Tutopatch(®) (Tutogen Medical, Inc., Alachua, FL, USA), a xenograft produced from bovine pericardium or the butterfly, an inlay tragal cartilage autograft. This is a retrospective study. We studied all cases of transcanal myringoplasty with Tutopatch and butterfly, performed by the same surgeon between April 2005 and May 2013. Perforations were secondary to chronic otitis media without cholesteatoma, perforation post ventilation tube or trauma. They were not exceeding one-third of the tympanic membrane surface for the Tutopatch and one quarter for the butterfly. We evaluated the anatomical success rate, complications and postoperative hearing results in both techniques. A total of 106 myringoplasties were performed: 66 with Tutopatch and 40 with butterfly with a mean follow-up of 16.5 and 5.2 months, respectively. Successful closure rates of Tutopatch and butterfly were 75.8% (P < 0.0001) and 85.0% (P < 0.0001), respectively. Myringitis controlled with topical antibiotics treatment occurred in 8 (12.1%) and 5 (12.5%) cases. Eighty percent of patients with Tutopatch had a mean residual air-bone gap within 10 dB, compared to 85.0% in patients with butterfly. When anatomically feasible, a transcanal approach myringoplasty with a Tutopatch(®) graft or butterfly appears to provide good anatomical and functional results. We show that both techniques provide good anatomical and functional results. The butterfly has the advantage to use an autograft, which is surgically easier because it does not require tympanomeatal flap elevation. We recommend the butterfly technique for non-marginal perforation not exceeding one quarter of the tympanic membrane after excision of the perforation edge and Tutopatch for bigger perforation or when standard autografts are not available. Myringitis is the only described complication without specific incidence.

Actual concepts in rhinosinusitis: a review of clinical presentations, inflammatory pathways, cytokine profiles, remodeling, and management.

Rhinosinusitis (RS) is a heterogeneous group of diseases. It is a significant and increasing health problem that affects about 15% of the population in Western countries. It has a substantial impact on patients' health-related quality of life and daily functioning and represents a huge financial burden to society and the health care system as a result of the direct and indirect costs. In addition, RS is not well-understood, and little is known about the etiology and pathophysiology. In the past decade, many papers have been published that have changed our understanding of RS. RS is commonly classified into acute and chronic RS based on symptom duration. In acute RS, an inflammatory reaction initiated by a viral infection characterizes most uncomplicated, mild to moderate cases. Therefore, the first line of treatment for these cases are intranasal steroids and not antibiotics. In severe and complicated cases, antibiotics combined with topical steroids remain the treatment of choice. On the other hand, chronic RS is actually subdivided into two distinct entities (chronic rhinosinusitis with and without polyps), as growing evidence indicates that these entities have specific inflammatory pathways and cytokine profiles. The authors review recent data regarding the clinical presentations, cytokine profiles, tissue remodeling, and modalities of treatment for each form of RS.
