BACKGROUND Many different surgical techniques have been developed to remove open mastoid cavities. In addition to autologous materials, alloplastic substances have been used. A very slow absorption of these materials and extrusion reactions have been reported. We investigated a newly developed, highly porous bone grafting material to eliminate open mastoid cavities, in an animal model. To chara...

PURPOSE To evaluate tympanic bulla healing after experimental lateral osteotomy in cats. METHODS Twenty adult cats were submitted to unilateral lateral bulla osteotomy and divided into two groups: cats of B1 group (n=10) were euthanized at 8 weeks and cats of B2 group (n=10), at 16 weeks postoperative. RESULTS Oblique lateral radiographs taken immediately postoperative showed interruption i...

Two cases of giant bullae were treated by intracavitary suction and drainage procedure under local anesthesia because of the poor pulmonary function. After staged bullectomy, the patients returned to normal life. The first case was admitted to our intensive care unit (ICU). Tube drainage was performed in the giant bulla of the left lung immediately after admission. One month after recovery from...

Background: Primary spontaneous pneumothorax is a relatively common condition in young adults. Although blebs and bullae are frequently found in patients with primary spontaneous pneumothorax, they are very rarely the actual cause of the pneumothorax. Objective: To assess our experience with chest computed tomography evaluation in patients with recurrent spontaneous pneumothorax as compared to ...

BACKGROUND Otitis media is a common disease in calves that can be subclinical, making antemortem on-farm diagnosis challenging. OBJECTIVES To evaluate the sensitivity and specificity of ultrasonography of tympanic bullae for the diagnosis of clinical and subclinical otitis media and to evaluate the reproducibility of the technique. ANIMALS Forty calves 19-50 days of age were selected from a...

Fluid-containing emphysematous bullae are an under-reported complication of chronic obstructive pulmonary disease. The roles of bronchoscopy in the work-up and of antibiotics in the treatment are undefined. This study reports the combined results from the analysis of 16 cases treated at the present authors' institution and 36 previously reported cases. The median age at presentation was 58 yrs ...

PURPOSE To report the results of the management of painfully symptomatic postoperative bullous keratopathy (PBK) by performing a nonpreserved human amniotic membrane (NP-AMT) transplantation in nine eyes with poor visual potential. METHODS A prospective, comparative, nonrandomized management of symptomatic PBK was done by performing a complete corneal de-epithelialization followed by a NP-AMT...

Bullous pemphigoid (BP) and mucous membrane pemphigoid (MMP) are autoimmune disorders involving IgG antibodies to basement membrane zone antigens [1]. The natural course of these diseases is that of exacerbations and remissions [2]. Older adults over the age of 60 and men are more likely to be affected [3]. BP manifests as tense, 1-3 cm fluid filled bullae on the skin [2]. The bullae may be on ...

Giant bullae are bullae that occupy at least 30 percent of a hemi thorax. This condition can rarely be idiopathic and not usually suspected in young patients with no risk factors. We describe a case of a giant solitary pulmonary bulla in a healthy young female with no known risk factors. 23-year-old female presented to the Emergency department with dyspnea and pleuritic right sided chest pain. ...
