CONTEXT Paranasal sinus cancer is considered rare, with an incidence of less than 1 per 100,000 per year, with the frontal sinus being the primary site in only 0.3%. We report a case of adenocarcinoma arising in the frontal sinus. DESIGN Case report. CASE REPORT A 59-year-old woman, secretary, came in February 1998 with a 4-month history of low intensity frontal headache. She denied contact...
OBJECTIVE To review the entity of respiratory epithelial adenomatoid hamartoma of the paranasal sinuses using an illustrative case example of frontal sinus hamartoma. METHODS Case report with review of the literature. RESULTS Respiratory epithelial adenomatoid hamartoma represents a benign process that is generally cured with conservative surgical resection of the involved area. Nevertheles...
Objective Sinonasal non-Hodgkin lymphoma (NHL) is a very rare condition. NHL located specifically in the frontal sinus is even rarer with only 14 cases in the literature reported to date. A unique case of diffuse large B-cell lymphoma of the frontal sinus that presented first and was treated as suspected Pott puffy tumor is presented along with a review of the literature. Case Report A 69-year-...
OBJECTIVES/HYPOTHESIS This study is undertaken to determine if the presence or absence of multiseptated frontal sinuses is associated with the presence or absence of supraorbital ethmoid cells (SOECs). STUDY DESIGN Analysis of prospectively collected data. METHODS Sixty consecutive patients with chronic rhinosinusitis were identified from a prospectively collected database at a tertiary-ref...
Achieving long-term, successful outcomes with endoscopic sinus surgery (ESS) can be challenging in patients with recalcitrant chronic rhinosinusitis (CRS). Local complications, including scar formation and ostial stenosis, can lead to recurrent blockage and subsequent relapse. The frontal sinus is particularly vulnerable to surgical failure given its narrow outflow and inaccessibility to topica...
INTRODUCTION Despite impressive advances in endoscopic approaches to the frontal sinus, the osteoplastic flap approach to the frontal sinus remains an important tool for surgically treating frontal sinus pathology. In this approach, the anterior table of the frontal sinus is opened wide while maintaining a hinged attachment to the overlying periosteum and soft tissue along its inferior border. ...
Agenesis of the paranasal sinuses is an uncommon clinical condition that appears mainly in the frontal (12%) and maxillary (5-6%) sinuses; in some populations, it appears at a higher proportion. This study investigated the prevalence of agenesis of the frontal sinuses using dental volumetric tomography (DVT) in Turkish individuals. The frontal sinuses of 410 patients were examined by DVT scans ...
Background. The frontal recess area represents a challenge to ENT surgeons due to its narrow confines and variable anatomy. Several types of cells have been described in this area. The agger nasi cells are the most constant ones. The frontal cells, originally classified by Kuhn into 4 types, have been reported in the literature to exist in 20%-41% of frontal recesses. Aim of the Study. To ident...
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.
Isolated or solitary neurofibromas of the paranasal sinuses are rare. Mostly, they involve the maxillary sinus and so far, a solitary neurofibroma of the frontal sinus has never been reported in the literature. We present a case of frontal sinus neurofibroma treated successfully with surgical excision. A 28-year-old male presented with forehead swelling and computed tomography images revealed a...
