OBJECTIVES Mastoid obliteration is used to obliterate the mastoid cavity following a mastoidectomy or to prevent the formation of a retraction pocket. This study evaluated the effectiveness of β-tricalcium phosphate and polyphosphate (β-TPP) for mastoid obliteration in middle ear surgeries in prospective human and animal studies. METHODS Twenty patients with chronic otitis media underwent mas...

IN the Journal of Anatomy and Physiology (xlvii., p. 391), I published a short paper on the " Comparative Anatomy of the Middle Ear." Among other subjects in that paper, I demonstrated the existence of a large plexus of nerves on the posterior surface of the tympanic bulla in several mammals of different orders. On account of its anatomical position, I named the structure the bullar plexus. The...

A 56-year-old woman visited our hospital for mild exertional dyspnea. Radiological investigations revealed a giant bulla of the left lung that was treated with video-assisted thoracoscopic bullectomy. The result of treatment was a better stamina, and, more strikingly, a major change of voice.

Bullous Keratopathy, a severe edema of the corneal stroma and epithelium with a characteristic bulla formation on the corneal surface, is a rare opthalmological emergency in cats. Rapidly progressive and uncontrollable by medical means, this condition will result in corneal perforation hours after initial presentation if left unattended. Its pathophysiology and treatment options are reviewed in...

Surgical bullectomy is the treatment of choice for giant emphysematous bulla. We report a case of successful nonsurgical treatment with bronchoscopic placement of one-way endobronchial valves that are currently under investigation for the treatment of end-stage emphysema. In patients who are poor surgical candidates, this noninvasive bronchoscopic treatment may represent a valuable alternative.

A 41-year-old woman developed skin vesicles one week before examination. She had been suffering from ulcerative colitis since the age of 30. Histologic examination of a vesicle showed a subepidermal bulla accompanied by mononuclear leukocyte infiltration intermingled with eosinophils and neutrophils. Eosinophilia was also noted. Direct immunofluorescent test revealed linear deposits of IgA in t...

Diffuse Cutaneous mastocytosis (DCM) occurs due to abnormal accumulation of mast cells in the skin. We report an 8-month-old infant presented papulovesicular lesions, predominantly on the trunk. Skin biopsy revealed subepidermal bulla, interspersed with mast cells, eosinophils and neutrophils. Direct immunofluorescence microscopy of perilesional skin revealed nonspecific deposition of IgM in gr...
