This clinical article presents a rare presentation of complete intrusion of a maxillary right primary central incisor. Routine examination of a 29-month old female patient revealed an intrusion injury where the primary central incisor was displaced through the floor of the nasal cavity. The traumatic impaction was erroneously diagnosed as an avulsion injury by the attending emergency room physi...

Frontal sinus outflow tract (FSOT) injury may occur in cases of frontal sinus fractures and nasoethmoid orbital fractures. Since the FSOT is lined with mucosa that is responsible for the path from the frontal sinus to the nasal cavity, an untreated injury may lead to complications such as mucocele formation or chronic frontal sinusitis. Therefore, evaluation of FSOT is of clinical significance,...

The aim of the study was to evaluate the performance of sniff nasal inspiratory pressure (SNIP) and MIP in individuals with spinal cord injury. We evaluated 26 patients with spinal cord injury. Mean FVC in those with tetraplegia was 52 +/- 19% of predicted, compared with 78 +/- 23% of predicted in those with paraplegia (p < 0.05). In contrast, the percentage of predicted SNIP was lower in those...

Objective Pneumocephalus is a rare complication that often occurs after traumatic skull base injury, leading to morbidity and mortality. Material and Method We present the case of a 42-year-old healthy man who injured himself when he stuck a metal stick into his left nasal cavity to relieve prolonged nasal obstruction. Immediate cerebrospinal fluid rhinorrhea and subsequent meningitis and pne...

Face basosquamous or metatypical carcinoma is a rare and controversial form of skin cancer. It is characterized by increased incidence of recurrence and distant metastases. We present the case of a patient of 71 years with an ulcerative lesion of 3/4 cm in the nasal pyramid. The injury occurred due to trauma to the nasal pyramid, produced 13 years ago. After investigation, which included ORL ex...

1 BackGROund In line with the modern trend toward minimally invasive surgery, the use of ultrasonic waves for cutting bone has recently been introduced in oral and maxillofacial surgery. This generally results in no visible injury to the adjacent soft tissues from the generated micromovements.1,2 In rhinoplasty, the lateral osteotomy technique should not only be precise, reproducible, and safe ...

Noninvasive ventilation (NIV) has been widely used to decrease the complications associated with tracheal intubation in mechanically ventilated patients. However, nasal ulcerations may occur when conventional masks are used for continuous ventilation. A total face mask, which has no contact with the more sensitive areas of the face, is a possible option. We describe 3 patients with acute respi...

Background and Objective: Nasal polyp is the most common benign mass of the nasal cavity and it is originated from nasal cavity or sinuses. Cytokeratins (CK) are intermediate filament proteins that provide mechanical support in epithelial cells. The purpose of this study was to compare the expression of cytokeratin 7 in epithelium of nasal polyps and nasal mucosa in chronic rhinosinusitis. Mate...

Introduction: Nose morphology depends on gender, ethnicity, and environmental conditions.&nbsp;It can be used in identification of the race and sex of persons whose identity is unknown. Nasal&nbsp;index is a useful tool in anthropometry. Methods: In this study, nasal parameters of Iranian males and females students were measured&nbsp;(nasal height, nasal width, and nasal index). This study was...

The olfactory ensheathing cell is a specialized glial cell that assists in growth of the axons of the olfactory sensory neurons as they are generated and regenerated throughout adult life. There is increasing evidence in animal models that transplantation of olfactory ensheathing cell promotes recovery after transplantation into the injured spinal cord. Olfactory ensheathing cell transplants ha...
