Background: Rhinolithiasis is masses that result from the deposition of salts around an intranasal foreign body. Rhinoliths are rare and rhinolithiasis is generally reported in the literature in single case studies. This study presents 21 cases of rhinolithiasis with a large series of clinical findings, diagnosis, and treatment. Methods: A total of 21 patients diagnosed with rhinolithiasis were identified. Clinical presentations, signs, and symptoms of the patients with radiological findings are presented, and x-ray diffraction analyses of three of the removed rhinoliths were performed to assess their mineralogical composition. Results: A total of 21 patients (9 male and 12 female patients; age range, 4–63 years) diagnosed with rhinolithiasis were reviewed in this study. The most common symptoms were noted as purulent rhinorrhea and nasal obstruction. The other symptoms were headache, oral malodor, and recurrent epistaxis. Nasal endoscopic examination was used for diagnosis of all patients. Endoscopic nasal examinations and computerized tomography (CT) findings revealed that rhinolithiasis was accompanied by sinusitis, chronic vestibulitis, allergic rhinitis, septum deviation, and squamous cell carcinoma. Rhinoliths were fully excised by using endoscopic nasal surgery. Mineralogical analyses of the three removed stones revealed dahllite [Ca ₅ (PO ₄ , CO ₃ ) ₃ OH]. Conclusion: Cases of rhinolithiasis are seen rarely. It should always be considered in patients complaining from long-term unilateral nasal obstruction and unilateral purulent rhinorrhea. The treatment involves the removal of the rhinolith and the use of appropriate antibiotic therapy to control local infection. Rigid nasal endoscopy is the most important method to be used in diagnosis and treatment.

Objectives: Recent studies on the etiopathogenesis of nasal polyps have shown that smoking and nonallergenic inhalants such as occupational dust exposure cause chronic inflammation of the nasal mucosa. These factors may be associated with nasal polyps. The aim of this study was to use laboratory tests to investigate the effects of smoking and allergens on the development of nasal polyps. Methods: The study included 60 consecutive patients with a diagnosis of nasal polyposis who were treated with functional endoscopic sinus surgery at our clinic and 25 smoker and 25 nonsmoker participants who constituted a control group. Results: In the patient and control groups, the mean absorbance value for cotinine in smokers was found to be statistically significantly lower than that in nonsmokers. There was a significant difference between the groups with respect to blood cotinine positivity. No significant difference was found between the groups in terms of allergy parameters. In the regression model, smoking was found to be the only significant risk factor for the development of nasal polyps, independent of smoking duration, absorbance value, or cotinine positivity. Conclusions: Smoking restriction and avoiding exposure to cigarette smoke by patients with nasal polyps may be an important strategy in the prevention and recurrence of nasal polyposis. No direct relationship was determined between allergy and nasal polyposis.

Objective: This study was performed to assess the complication and diagnostic rates of computed tomography (CT)-guided transthoracic needle biopsy of pulmonary parenchymal and mediastinal lesions. Methods: Patients who were suspected to have a malignancy based on chest imaging and CT and could not be otherwise diagnosed were evaluated. Results: Sixty-five patients were included; 48 (73.8%) were male and 17 (26.2%) were female. Their average age was 58 years. The lesion size ranged from 11 to 105 mm. The most common specific histologic subtype was adenocarcinoma, and the least common was lymphoma. The diagnostic rate was 90.8%. The mean complication rate was 15.4%. Statistically significant associations were found between the complication rate and needle size and between the needle path length and lesion size. Conclusion: CT-guided needle biopsy is an effective diagnostic method for patients with mediastinal and parenchymal lesions before thoracotomy. This method can also reliably differentiate benign and malignant tumors.

Objective: We report an extremely rare case of giant fibrovascular polyp of the hypopharynx.Method: We present a 49-year-old man who had increasing difficulty swallowing, advanced respiratory distress and weight loss, as well as a hypopharyngeal mass protruding from his mouth.Results: Diagnosis was confirmed by endoscopic examination and computed tomography. A tracheostomy was required due to laryngeal obstruction by the regurgitated mass. The giant polyp was removed via per-oral endoscopic excision under general anaesthesia.Conclusion: Fibrovascular polyps occur most commonly in the cervical oesophagus, and are extremely rare in the hypopharynx. They can grow to a very large size over several years. We discuss the symptoms, diagnosis and surgical treatment techniques for upper aerodigestive tract fibrovascular polyps, in the light of the literature.
