“…This theory has been supported by studies in animal and human models. l3 , 14,38 Several authors have noted that after ostial occlusion of the maxillary sinus, specific mechanical changes occur. Upon the complete occlusion of the sinus, reabsorption occurs, along with the buildup of negative pressure from within the antrum.…”

“…SSS is a challenging diagnosis because it can be diagnosed in a subgroup of patients, who have the sinusal and orbital changes, but no specific symptoms of chronic rhinosinusitis. Kass et al 13 demonstrated in their study, comparing the pressure of the chronic maxillary atelectasis sinus with chronic maxillary sinusitis sinus and with a normal maxillary sinus, that the negative pressure is the basis of the chronic maxillary atelectasis. The negative pressure originates in the osteomeatal complex obstruction, determines bone remodeling and one of the most important signs, enophthalmos 2,6,7 .…”

BACKGROUND. Silent sinus syndrome (SSS) is known as a relatively new pathology with clinical characterizations, represented by the facial asymmetry determined by progressive enophthalmos and hypoglobus and the absence of nasal symptoms. The theory that sustained this pathology is based on the negative maxillary pressure and the chronic evolution of symptomatology. CASE REPORT. A 49-year-old white female presented in our clinic for facial asymmetry, right facial pressure, right depression of the orbital floor and hypoglobus, without diplopia. The CT scan showed an opaque right maxillary sinus with the depression of the orbital floor. CONCLUSION. The pathogenesis, clinical and imagistic features are the most important in the SSS for diagnosis and correct treatment.

Objective: To measure the intra-sinus pressure and the maxillary sinus functional efficiency (MSFE) in individuals with chronic facial pain after conservative or conventional endoscopic maxillary surgery, as well as in controls. Method: Sinus manometry was performed 5 times during inhalation. Results: The resemblance of pressure values comparing those treated with minimally invasive surgery and controls was remarkable, while traditional surgery significantly decreased intrasinusal pressures. The MSFE was 100% in the three tested times for controls, close to that in those submitted to minimally invasive surgery (98.3%, 98.8%, and 98.0%) and significantly impaired after conventional surgery (48.8%, 52.1%, 48.5 %, p,0.01). All patients submitted to minimally invasive surgery remained pain-free after three months of surgery, relative to 46.7% of the submitted to conventional surgery (p,0.05). Conclusion: Minimally invasive sinus surgery is associated with functionality of the chambers that resemble what is found in normal individuals.Keywords: facial pain, nasal cavities, manometry, biophysical model, endoscopic surgery. RESUMOObjetivo: Medir a pressão intrasinusal e a eficiência funcional do seio maxilar (EFSM) em indivíduos com dor facial crônica após cirurgia endoscópica maxilar conservadora ou convencional em comparação a pessoas normais. Método: A manometria do seio foi feita 5 vezes durante a inalação. Resultados: A semelhança entre os valores das pressões comparando aqueles tratados com cirurgia minimamente invasiva e os controles foi notável, enquanto que na cirurgia tradicional houve diminuição significativa das pressões intrasinusais. A EFSM foi 100% nas três vezes testadas nos controles, de modo muito semelhante ao que foi observado naqueles submetidos a cirurgia minimamente invasiva (98,3%, 98,8%, e 98,0%) e significativamente diminuída naqueles submetidos a cirurgia convencional (48,8%, 52,1%, 48,5 %, p,0,01). Todos os pacientes submetidos a cirurgia minimamente invasiva mantiveram-se sem dor três meses depois da cirurgia, comparados a 46,7% naqueles submetidos a cirurgia convencional (p,0,05). Conclusão: Cirurgia minimamente invasiva está associada a funcionalidade das câmaras sinusais que se assemelha ao que é observado em indivíduos normais.Palavras-chave: dor facial, cavidades nasais, manometria, modelo biofísico, cirurgia endoscópica.The facial sinuses develop as outgrowths from the nasal cavity, hence communicating directly or indirectly to the nose. The ostium meatal complex (OMC) connects the nasal cavity to the paranasal sinuses. Its peculiar structure and shape allows the maxillary sinus to ventilate in a "low pressure system". Accordingly, the occlusion of the OMC results in a slow but progressive increase in the intra-maxillary sinus pressure which, in turn, predisposes to tissue hypoxia, a powerful inducer of nitric oxide (NO) synthesis and pain. It has been demonstrated that NO levels correlate with OMC obstruction 1,2,3,4 . Sinus headache is a term widely assigned to individuals ...
