Agger nasi cells contribute to nasofrontal duct (NFD) obstruction and chronic frontal sinus disease. To investigate this relationship, we conducted a review of the surgical outcome and computed tomographic imaging in 26 patients with chronic frontal sinusitis. Coronal and sagittal images were used to delineate the anatomic variability and mucosal disease in the NFD and frontal sinus region. Data from coronal and sagittal images were compared. The results were also correlated with the outcome of frontal sinus surgery in patients with a clinical history of chronic frontal sinus disease. Our data suggest that agger nasi cell pneumatization with narrowing of the frontal sinus outflow tract is a significant cause of persistent frontoethmoid pain and chronic frontal sinusitis. Sagittal reformatted images are more capable than coronal images of demonstrating agger nasi cell encroachment on the NFD, as well as NFD mucosal disease. Endoscopic frontal sinusotomy is an effective treatment for chronic frontal sinus disease

BACKGROUND: Inverting papillomas usually originate from the lateral wall of the nose and sporadically from the ethmoid, maxillary, sphenoid, or frontal sinuses. Intracranial extension and dural penetration is rare and often associated with recurrent disease that has degenerated into squamous cell carcinoma. A case of inverting papilloma with dural penetration in the absence of malignant degeneration has prompted an investigation into the incidence and treatment of dural invasion by benign inverting papilloma. METHODS: A literature search revealed 1468 cases of inverting papilloma. A detailed analysis was performed to obtain data on the incidence of intracranial invasion. RESULTS: Of the 1468 cases, 5 were noted to be associated with intracranial extension without histologic evidence of malignancy (0.34%). Treatment consisted of surgery alone in 3, radiotherapy in 1, and combined therapy in the last patient. Dural invasion was documented histopathologically in one case. CONCLUSION: Intracranial extension and dural penetration of benign inverting papilloma is extremely rare, and a uniform treatment plan has not been established. Further investigation is necessary in the pathophysiology and management of intracranial inverting papilloma

Chronic sinus disease associated with progressive mucosal disease is often a cause for anosmia. Despite aggressive allergic, medical, and surgical intervention, long-term relief of anosmia has been difficult to document. Fifty patients sought treatment for subjective anosmia and symptoms of progressive sinusitis and underwent endoscopic sinus surgery. After surgery 52% maintained significant improvement in smell by subjective measures that correlated with objective olfactory University of Pennsylvania Small Identification test ('UPSIT') results. Of the remaining patients, some had intermittent improvement, but most remained hyposmic or anosmic despite clinically well-healed ethmoid surgical beds. Of the preoperative and postoperative historical, clinical, and radiological data analyzed, severity of the presenting sinus disease (defined as stage II In the Kennedy staging criteria or disease extending beyond the ethmoids on preoperative computed tomography scan) and persistent mucosal disease in the surgical bed are associated with persistent anosmia (p = 0.005)

During the past 25 years, the Radiation Therapy Oncology Group (RTOG) has played a major role in head and neck cancer clinical research. The major research themes for recent and currently active trials have been: (a) combined modality therapy, (b) altered fractionation radiotherapy, (c) hypoxic cell sensitizers, (d) organ preservation, (e) chemoprevention, and (f) clinical/laboratory correlations. For advanced operable disease, the RTOG showed improved local-regional control with postoperative radiotherapy as compared to preoperative radiotherapy for carcinoma of the supraglottic larynx and hypopharynx. This established the use of surgery followed by postoperative radiotherapy as the standard treatment in subsequent RTOG and Intergroup trials for operable disease. For advanced inoperable disease, the RTOG demonstrated the feasibility of testing altered fractionation radiotherapy in a multiinstitutional clinical trials setting. A Phase III trial comparing hyperfractionation and accelerated fractionation to conventional fractionation is now in progress. Phase I/II combined modality studies established the efficacy of concurrent high-dose cisplatin and radiotherapy in the treatment of advanced disease and provided the basis for further testing in Phase III trials for nasopharyngeal carcinoma, larynx preservation, and high-risk advanced operable disease. Analysis of the extensive RTOG Head and Neck Cancer database established the incidence of second malignancies and their adverse impact on patients whose initial tumors were cured by radiotherapy, and provided the basis for chemoprevention trials. Recursive partitioning analysis identified 6 distinct prognostically homogeneous patient groups based on pretreatment tumor or patient characteristics and/or treatment variables. Retrospective analysis identified tumor p105 antigen density as an independent prognostic indicator in patients irradiated for head and neck cancer. Future trials will continue to focus on the reduction of morbidity and mortality, and improvement of the quality of life of head and neck cancer patients through innovative radiotherapy delivery, multimodality approaches, use of chemical and biological modifiers, and other novel therapies, identification of clinical and biological prognostic indicators, and prevention or diminution of acute morbidity and late complications of the disease and its treatment

The ostiomeatal complex has been identified as an important anatomic region in the pathogenesis of sinusitis. Functional endoscopic techniques rely on removal of mucosal disease from this site to improve drainage and aeration. Structural variations and the use of a sharp blade to create the infundibulotomy can result in inadvertent injury to the orbit. To avoid orbital penetration we perform the infundibulotomy with a curved, blunt dental elevator and displace the uncinate with its medial and lateral mucosa toward the middle turbinate. This stretches the infundibulum to reveal the maxillary ostium at its depth. The remaining mucosal attachments of the uncinate process are then incised under direct vision, and the complex is resected, creating an initial wide antrostomy. This technique has avoided orbital penetration in 700 cases in patients with early or late stages of mucosal disease

Metastases are occasionally associated with cutaneous squamous cell carcinoma but only rarely with basal cell carcinoma. There are approximately 200 cases of metastases from basal cell carcinoma reported in the world literature. We describe 6 additional cases. All of our patients demonstrated recurrence at the primary site before they developed their metastases. Metastases presented in subcutaneous tissue, cervical lymph nodes, bone, and lung between 1.5 and 14 years after initial treatment of the primary lesion. The long interval seen in these patients between the initial treatment of the primary and the development of metastases underscores the need for long-term follow-up in what is often thought to be a nonaggressive, nonmetastasizing malignancy

A prospective randomized study comparing the effectiveness of triamcinolone acetonide and beclomethasone dipropionate nasal sprays in the treatment of allergic or vasomotor rhinitis was conducted at New York University Medical Center Both medications were used at their recommended dosages. Fifty patients were evaluated during a 2-month treatment period. Nasal airflow and resistance were quantified by anterior active rhinomanometry using the Rhinotest microprocessor rhinomanometer. The patients' subjective complaints were graded on a standard questionnaire. Both steroid inhalants were highly effective in relieving local symptomatology and the subjective improvement in nasal obstruction correlated with rhinomanometric assessment of the nasal airway. Triamcinolone acetonide used once daily represents an alternative to the twice daily beclomethasone dipropionate nasal steroid spray currently available for the treatment of rhinitis

We present a retrospective comparison of intravenous sedation and general anesthesia techniques employed at New York University-Bellevue Medical Center for functional endoscopic sinus surgery. Some authors have stressed the use of local anesthesia with intravenous sedation in order to avoid complications and reduce blood loss. We have reviewed 232 patients who underwent 401 consecutive ethmoidectomies and maxillary antrostomies. Local anesthesia, employed in 64% of patients, carried an estimated blood loss of 23 mL per side. General anesthesia was associated with an average blood loss of 58 mL per side. The rate of operative complications for local anesthesia was 8.7% per patient, with a 1.6% rate of major complications per side. General anesthesia carried an overall complication rate of 2.4% per patient, with no major complications. General anesthesia is a relatively safe and viable option for endoscopic sinus surgery that in selected cases may be preferable to local anesthesia
