Frontal Sinus

Pneumosinus dilatans frontalis: A case report

December 1, 2005     Giacomo De Riu, MD; Alessandro Bay, MD; Antonio Tullio, MD
Deformity of the forehead is usually the first clinical presentation of the abnormally large frontal sinus caused by pneumosinus dilatans. We report the diagnosis and surgical treatment of a case. The type of osteotomy we describe is recommended as a method of surgical treatment for this condition when the aesthetic problem is the major complaint.

Total necrosis of the intranasal structures and soft palate as a result of nasal inhalation of crushed OxyContin

July 31, 2005     David Greene, MD, FACS
Nasal inhalation of substances such as cocaine has long been linked to septal necrosis and more recently to palatal perforation. This report describes the case of a 37-year-old man who was addicted to crushed OxyContin (sustained-release oxycodone HCl) tablets and who presented with total necrosis of the septum, sinuses, and soft palate. To the best of the author's knowledge, this is the first reported case of nasal and palatal necrosis linked to nasal inhalation of crushed OxyContin, which is a relatively new form of drug abuse. The pathophysiology of drug-induced sinonasal disease and a review of the literature are also presented.

Sinonasal leiomyoma: Report of 2 cases

April 1, 2005     A.K. Agarwal, MS; Ramanuj Bansal, MS; Deepti Singhal, MS

Leiomyomas are benign smooth-muscle tumors that are common in the alimentary tract, uterus, skin, and subcutaneous tissue. They are very uncommon in the upper respiratory tract and rare in the nasal cavity and paranasal sinuses. To the best of our knowledge, only 23 such cases have heretofore been published in the literature. We report 2 new cases of sinonasal leiomyoma that originated at different sites in the nasal cavity. We also discuss the various investigative and therapeutic modalities available.

Primary non-Hodgkin's lymphoma of the frontal sinus: Case report and review of the literature

Non-Hodgkin's lymphoma of the sinonasal tract is an uncommon lesion, representing 1.5 to 15% of all lymphomas. Most cases of primary non-Hodgkin's lymphoma of the sinonasal tract occur in the maxillary sinus, ethmoid sinus, and nasal cavity; its occurrence in the frontal sinus is extremely rare. We report a case of primary type B non-Hodgkin's lymphoma of the frontal sinus in a 43-year-old man. The patient complained of frontal headaches that had not improved with analgesic drugs, and he presented with a frontal bulge that involved the left upper eyelid; the bulge had progressively enlarged over a 3-month period. A biopsy of the mass identified the type B non-Hodgkin's lymphoma. Immunohistochemical study not only confirmed the histologic type of the tumor, it also provided some important information about the primary tumor site. Advances in immunohistochemistry have shown that type B non-Hodgkin's lymphoma is more common in North American and European patients, whereas subtype T is more common in Asians and in some Latin Americans. The treatment of this condition is still controversial, but the combination of radiotherapy and chemotherapy has yielded the best results in all stages of the disease.
