Position paper on nasal obstruction: evaluation and treatment.

Nasal obstruction (NO) is defined as the subjective perception of discomfort or difficulty in the passage of air through the nostrils. It is a common reason for consultation in primary and specialized care and may affect up to 30%-40% of the population. It affects quality of life (especially sleep) and lowers work efficiency. The aim of this document is to agree on how to treat NO, establish a methodology for evaluating and diagnosing it, and define an individualized approach to its treatment. NO can be unilateral or bilateral, intermittent or persistent and may be caused by local or systemic factors, which may be anatomical, inflammatory, neurological, hormonal, functional, environmental, or pharmacological in origin. Directed study of the medical history and physical examination are key for diagnosing the specific cause. NO may be evaluated using subjective assessment tools (visual analog scale, symptom score, standardized questionnaires) or by objective estimation (active anterior rhinomanometry, acoustic rhinometry, peak nasal inspiratory flow). Although there is little correlation between the results, they may be considered complementary and not exclusive. Assessing the impact on quality of life through questionnaires standardized according to the underlying disease is also advisable. NO is treated according to its cause. Treatment is fundamentally pharmacological (topical and/or systemic) when the etiology is inflammatory or functional. Surgery may be necessary when medical treatment fails to complement or improve medical treatment or when other therapeutic approaches are not possible. Combinations of surgical techniques and medical treatment may be necessary.

Treatment results for ethmoid sinus carcinoma.

OBJECTIVE: The aim of this study was to describe the results of treatment in patients with ethmoid sinus carcinoma. MATERIALS AND METHOD: We performed a retrospective study of 34 patients with carcinoma of the ethmoid sinus, and collected the following data: age, sex, employment, tobacco and alcohol consumption, tumour-node-metastasis stage, treatment, and survival. RESULTS: The mean patient age was 64 years. Seventy-six per cent of patients were men and 24 per cent women. Squamous cell carcinoma was the most frequent histological tumour type (44 per cent). Eleven patients were classified as T(2), six as T(3), six as T(4a) and 11 as T(4b). Two patients (6 per cent) had nodal metastasis at the time of diagnosis. The anterior skull base was involved in 17 patients (50 per cent) and the anterior orbital contents were affected in seven patients (21 per cent). The five-year actuarial observed survival rate for all patients was 44 per cent. CONCLUSIONS: Combined treatment with surgery and post-operative radiotherapy permitted good local control in patients with ethmoid sinus carcinoma. We do not recommend prophylactic neck treatment for ethmoid sinus carcinoma.

[Epidemiologic analysis of 72 carcinomas of the nasal cavity and paranasal sinuses]. / Análisis epidemiológico de 72 carcinomas de fosas y senos paranasales.

OBJECTIVE: The aim of this study is to define the epidemiological aspects of carcinoma of the nasal cavity and paranasal sinuses. MATERIAL AND METHODS: We performed a retrospective study of 72 carcinomas of the nasal cavity and paranasal sinuses. Various sites, age and sex distribution, drug consumption, TNM stage grouping and treatment were reported. RESULTS: The average age was 63. Seventy- five percent of patients (54/72) were male and 25% (18/72) female. The site of origin was paranasal sinuses in 46 patients (64%), 30 in ethmoid sinus, 15 in maxillary sinus and 1 in sphenoid sinus. Twenty-six patients (36%) were located in nasal cavity. Squamous cell carcinoma was the most frequent histological type in both localizations. The 5-year adjusted survival rate for all patients was 60% (IC: 54-66), 36% (IC: 28-44) for paranasal sinus carcinoma and 86% (IC: 79-93) for nasal cavity carcinoma. The 5-year adjusted survival rate according to the T distribution in 46 carcinomas paranasal sinus was 80% T2, 71% T3, 19% T4a and 6% T4b.(p = 0.0002). CONCLUSIONS: Carcinoma of nasal cavity and paranasal sinuses represent a group of tumors that differ from the rest of carcinomas of the head and neck.

[Nasal sinus metastasis of renal carcinoma. A case report]. / Metástasis nasosinusal de un carcinoma renal. A propósito de un caso.

Renal cell carcinoma is the primary neoplasm which most frequently metastasizes in the nasosinusal region. We present a case of a 51-year-old man who was nephrectomized for a renal cell carcinoma. A year later, he presented a left nasosinusal lesion. The biopsy was conclusive for renal cell metastasis. A paralateronasal and bicoronal approach was used. Currently, 6 years later the patient is free of local disease, but he presents cutaneous metastasis. Renal cell nasosinusal metastasis is found in a context of disseminated disease. Symptoms are unspecific, but the epistaxis constitutes the most common sign due to the significant vascularizations of the tumor. Definitive diagnosis is obtained from the biopsy of the tumor. TC and RM illustrated the lesion's extension and involvement of adjacent structures. Prognosis is poor. The survival rate fluctuates between 15-30% at 5 years. Surgery is the elective treatment but should be considered on an individual basis.
