OBJECTIVES To develop and standardize a technique for measuring nasal nitric oxide (NO) output in children and to determine normal values in this population. STUDY DESIGN Prospective study evaluating a new technique for measuring nasal nitric oxide in a cohort of normal patients and a cohort of patients with nasal disease. METHODS Nasal NO was measured using an aspiration technique, aspirat...

BACKGROUND Reconstruction of nasal alar defects is difficult because of the complex anatomy of the region. A frequent challenge in this area is repair of small cutaneous defects involving the lateral nasal supratip and the superior alar groove. OBSERVATIONS An oblique advancement flap that uses laxity from the nasal sidewall is described. Its benefits and limitations are compared with those o...

The paranasal sinuses remain elusive both in terms of function and in the proximate mechanism of their development. The present study sought to describe the maxillary sinuses (MSs) in three species of callitrichid primates at birth, a time when secondary pneumatization occurs rapidly in humans. The MSs were examined in serially sectioned and stained slides from the heads of two Callithrix jacch...

Hemangiomas of the nose are very rare lesions.They may be found in both paediatric and adult population.The various modalities treatment range from medical management to surgical management.We reporting a benign vascular lesion near nasal tip at soft triangle aesthetic subunit 64 year old male which was treated by simple excision using electrocautery primary closure. Histopathological examinati...

BACKGROUND Scientific evidence showed that rapid maxillary expansion (RME) affects naso-maxillary complex, increasing nasal width and volume. This study aimed to evaluate nasal changes induced by rapid maxillary expansion with different anchorage and appliance design by using low dose and cone beam computed tomography. METHODS A total of 44 patients (20 males, mean age 8y 8 m ± 1y 2 m; 24 fem...

OBJECTIVES/HYPOTHESIS To evaluate the correlation between growth differences of the face and nasal septal deviation, and to evaluate whether developmental differences of the face have an effect on nontraumatic nasal septal deviation (DNS). STUDY DESIGN Retrospective study. METHODS Twenty-five patients with DNS who underwent facial aesthetic surgery and had an ostiomeatal unit-computed tomog...

BACKGROUND Nasal defects resulting from tumor resection are preferably rehabilitated with implant-retained nasal prostheses. Aftercare, clinical outcome of the implants, and patients' satisfaction with implant-retained nasal prostheses were assessed. METHODS Twenty-eight consecutive patients needing total rhinectomy because of tumor resection between 1998 and 2013 were treated according to a ...
