OBJECTIVE To establish normal ranges for nasal bone length measurements throughout gestation and to compare measurements in two subsets of patients of different race (African-American vs. Caucasian) to determine whether a different normal range should be used in these populations. METHOD Normal nasal bone length reference ranges were generated using prenatal measurements by a standardized tec...

A rostrocaudal (RCd) nasal view was developed in large breed mesaticephalic dogs using a complete, subsequently sectioned, skull and cadaver specimens to optimise the radiographic technique and evaluate normal anatomic features. Gelatin was placed in one nasal passage of the cadaver specimens to mimic the effects of nasal pathology. The latter specimens and 18 clinical cases with suspected nasa...

An osteotomy must be performed in almost all types of external nose correction. By mobilising the bony skeleton, the nose may be sculpted into the desired shape and position. The osteotomy is carried out as gently as possible in an effort to minimize postoperative swelling and soft tissue bleeding. Finger and sharp chisels are used. Nasal bones are accessed through a short intercartilaginous in...

AMONG ALL THE POSSIBLE COMPLICATIONS OF AESTHETIC RHINOPLASTY, A RARE ONE IS THE DEVELOPMENT OF CYSTIC MASSES ON THE NASAL DORSUM: several theories suggest that cysts develop commonly by entrapment of nasal mucosa in the subcutaneous space, but they can also originate from foreign body reactions. This report deals with two cases of nasal dorsum cysts with different pathogenesis: both patients h...

OBJECTIVE To determine the number of ultrasound examinations necessary for training sonographers to examine accurately the fetal nasal bone at 11-14 weeks' gestation. METHODS Fifteen sonographers with experience in measuring nuchal translucency were asked to examine the nasal bone during the routine 11-14-week scan. The supervising doctor recorded if the sonographer succeeded in obtaining the...

extramedullary plasmacytoma (emp) is a rare neoplasm of soft tissue which usually arises in the respiratory tract, nasal cavity, sinuses and nasopharynx. multiple extramedullary plasmacytomas are extremely rare, especially those that are not associated with multiple myeloma.we describe multiple primary emp in a 37 year old man, without involvement of bone or bone marrow. emp usually has a good ...

AIM The aim of the study is to estimate the diagnostic sensitivity and utility of high-resolution ultrasonography (HRUS) in comparison with a gold standard technique in the diagnosis of the nasal fracture. PATIENTS AND METHOD Using a retrospective study design, facial Computed Tomography (CT) and HRUS examinations were performed on 87 consecutive patients with nasal trauma. Ultrasonograms wer...

Nose Lateral osteotomy is known as a major constituent of nose plastic surgery to correct nasal bone deformity and reducing nasal bone width. Different methods of osteotomy have been introduced so far that are categorized into two common internal and external methods. The surgeon has little control on this phase of nose plastic surgery. Several complications have been mentioned for Lateral oste...

OBJECTIVES We sought to evaluate the effectiveness of a number of surgical maneuvers in nasal reconstruction of a diverse population of patients undergoing skull base surgery. Study design We conducted a retrospective review of a cohort of patients undergoing nasal reconstruction during surgery of the anterior skull base and craniovertebral junction. METHODS All patients undergoing skull base...

BACKGROUND Bone microarchitecture is a significant determinant of bone strength. So far, the assessment of bone microarchitecture has required bone biopsies, limiting its utilization in clinical practice to one single skeletal site. With the advance of high-resolution imaging techniques, non-invasive in vivo measurement of bone microarchitecture has recently become possible. This provides an op...
