The nasal cavity harbors a wide variety of benign and malignant neoplasms. Benign neoplasms include those arising in epitelial and soft tissues. Hemangioma is an infrequent neoplasm of the nasal cavity, mostly arising in the mucosa and rarely in the bone. We report a case of an intraosseous cavernous hemangioma arising from the nasal floor in a 51 years old woman.

Certain dialects of Brazilian Portuguese (BP) show signs of nasal coda restoration (NCR). Results of an instrumental study suggest that stressed, word-final nasal vowels terminate in a velar nasal stop, though word-final nasal stops are presumed to be banned in BP. Four BP speakers uttered words ending in a stressed nasal vowel. A split flow mask sampled nasal and oral airflow. Complete oral oc...

BACKGROUND Tongue flap is a good option to close a complicated palatal fistula in cleft patients. Most surgeons advocate a double-layer closure to decrease the recurrence rates. In this study, we have reported our experience with a modified single-layer closure with tongue flap in cleft patients. METHOD All cases done by a single surgeon using this modified technique in a period of 10 years w...

PURPOSE Insight into the bone volume and position of natural teeth is essential when placing implants to retain nasal prostheses. This paper describes a series of three cases in which a new method was applied for implant placement in the nasal floor of dentate patients using digital planning techniques. MATERIALS AND METHODS With the aid of computer software, digital planning of implants in t...

Successful treatment of congenital and acquired conditions affecting the palate depends on an understanding of its functions. As the floor of the nose, it provides part of the airway, isolating nasal cavity from obstruction by food during mastication, and as the roof of the mouth, it provides a surface against which food may be broken up by the tongue and neatly passed back as manageable boluse...

Oro-antral communications are frequent complications in oral surgery, and generally occur after molar extractions, maxillary sinus elevations or dental implant procedures. The presence of these defects may increase the morbidity and often need a surgical approach. The present report describes an oro-antral communication in a 52-year-old female who presented a 2 week-course of painless nasal obs...

OBJECTIVE To analyze the radiographic, anatomic, and histologic characteristics of the nasal septal swell body. DESIGN Computer-aided analysis of magnetic resonance images (MRIs) and histologic examination of cadaveric nasal septa. SETTING Tertiary medical center. PATIENTS Fifty-four head MRI studies were performed on adult live patients; we also used 10 cadaveric nasal septa. MAIN OUTC...

This acoustic study investigates voiceless stops in Guaraní that are described as transparent to nasal harmony. Voiceless stops in oral versus nasal contexts are examined in relation to theoretical issues of locality and phonetic implementation. First, the oral/nasal and voicing properties of the stops are considered in connection to proposals in phonological theory that feature spreading produ...

IMPORTANCE Numerous techniques have been described to repair nasal septal perforations (SPs). However, many are technically challenging, with varying degrees of success. OBJECTIVE To evaluate the use of polyethylene (Medpor; Porex Technologies) implants in the closure of nasal SPs. DESIGN AND SETTING Prospective cohort study in an academic research setting. PARTICIPANTS Fourteen patients ...

We are the first to evaluate the impact of the trading floor closure on the corresponding efficiency of the stock price formation process on the Toronto Stock Exchange (TSX). Utilizing short-horizon return predictability as an inverse indicator of market efficiency, we demonstrate that while the switch to all electronic trading resulted in higher trading activity and lower trading costs, the in...
