BACKGROUND Functional rehabilitation of patients afflicted with severe mandibular and maxillary alveolar atrophy might be challenging especially in malformed patients. METHODS Treatment planning using sinus lifting and implant placement before Le Fort I maxillary osteotomy in a patient with severe mandibular and posterior maxillary alveolar atrophy and skeletal class-III conditions due to cle...

BACKGROUND The sinus lift was first described in 1974 and it has proven to be a predictable procedure ever since. The complications of this surgical procedure are reported in the literature to be low, and can include acute maxillary sinusitis, scattering of the grafting material into the sinus cavity, wound dehiscence and Schneiderian membrane perforations. We aimed to evaluate the rate of acut...

Radiography of the maxillary sinuses is often undertaken using computed tomography, magnetic resonance imaging, or the occipito-mental plain x-ray film projection. However the panoramic radiograph has been found superior to the latter for detection of “cyst-like densities.” [1]. The occipito-mental technique, first described by Waters and Waldron, clearly demonstrates the superior, inferior and...

Silent sinus syndrome (SSS) is an uncommon disease characterised by enophthalmos, caused by ipsilateral maxillary sinus atelectasis. The diagnosis is clinical with radiological confirmation. The treatment has two objectives: to regulate the aeration of the maxillary sinus through achieving normal nasal cavity drainage and to restore the orbital architecture. A case of SSS treated in our hospita...

INTRODUCTION The present study was undertaken to evaluate the anatomy of the maxillary sinus in relation to its position and the height of its septa, using cone beam computed tomography (CBCT). MATERIALS AND METHODS In this descriptive retrospective study, 300 CBCT images of maxillary sinuses of patients with posterior maxillary edentulism were evaluated. The maxillary sinus septa were evalua...

OBJECTIVES The maxillary sinus mucosa is reported to recover to preoperative sterility after sinus floor elevation. However, when drainage of maxillary sinus is impaired, recovery can be delayed and maxillary sinusitis can occur. Therefore, in this study, we investigated the correlations between anatomic variants that can interrupt the ostium of the maxillary sinus and incidence of complication...

Purpose Analyzing different patterns of maxillary sinus septa in cone-beam computed tomography (CBCT) images and predicting maxillary sinus membrane perforations. Materials and Methods In this cross-sectional study, CBCT images of 222 patients ranging from 20 to 81 years old were evaluated. One hundred fifty-two patients (93 females and 59 males) who had maxillary sinus septa in axial views w...

mucoceles are defi ned as chronic, cystic lesions in the paranasal sinuses. when the mucocele content becomes infected, the lesion is defi ned as mucopyocele. most mucoceles are located in the frontal and anterior ethmoid sinuses and normally they involve the frontal-ethmoid complex, expanding to the superior-medial region of the orbit, leading to ocular disorders; maxillary sinus presentation ...

BACKGROUND AND PURPOSE The size of the primary lesion and the lymph node metastasis are critical indicators for the patient prognosis. Here we attempted to assess the correlation between these 2 prognostic parameters in patients with oropharyngeal, hypopharyngeal, oral, or maxillary sinus cancer. METHODS We retrospectively studied 66 patients with oropharyngeal or hypopharyngeal (n = 24), ora...
