A unique case is presented of a penetrating injury of the parotid gland and complete transection of the cartilaginous portion of the external auditory canal by a tree branch. A subsequent superficial parotidectomy along with end-to-end anastomosis of the external auditory canal and appropriate antimicrobial therapy was successful. A review of the literature did not reveal any previous similar cases.
Cancer of the oral cavity is of growing concern worldwide. In the Micronesia, there has been a recent increase in use of betel nut and tobacco chewing in addition to already existing problem of smoking and alcohol drinking. These deleterious habits have further added the risk for development of oral cancers in the Marshall Islands. The oral cancers have good prognosis, which is directly related to the early diagnosis and treatment. Advanced staged cancers need mutilating surgery in addition to radiotherapy and carry high mortality rate. The epidemiology, etiology and recent approaches in the management of oral cavity cancer has been discussed along with a case report of advanced cancer of the floor of the mouth from the Marshall Islands.
Malignant otitis externa is a rare but potentially fatal disease of the external auditory canal seen mostly among elderly, diabetic or immunocompramised patients. The causative organism is mainly Pseudomonas aeruginosa. The disease spreads rapidly, invading surrounding soft tissues, cartilage and bones causing their necrosis and even spreading to the cranial nerves. The disease can be fatal if treatment is not aggressive and timely, especially if it spreads outside the auditory canal with involvement of the cranial nerves. Treatment is mainly medical with antipseudomonal drugs like the third generation cephalosporin and the fluoroquinolones and local debridement. With aggressive treatment the mortality rate from this disease, which used to be 50% in the past has now been reduced to 10-20%. The pathophysiology of the disease, clinical presentation, diagnosis, treatment and the outcome has been discussed and reviewed.
