BACKGROUND: Juvenile nasopharyngeal angiofibroma often attaches firmly to the adjoining bony region around the sphenopalatine foramina-sphenopalatine fossa-pterygomaxillary fissure. This can result in hourglass-shaped constriction and predispose to incomplete resection (residual disease) with a transpalatal approach. This paper describes attempts to address this 'inaccessible' area with a novel instrument, used since 2012. METHODS: Measurements of the sphenopalatine foramen, nasal septum, posterior nasopharyngeal wall and hard palate were undertaken in 20 skulls and 10 computed tomography scans (lateral extension)...

Facial shape is the basis for facial recognition and categorization. Facial features reflect the underlying geometry of the skeletal structures. Here we reveal that cartilaginous nasal capsule (corresponding to upper jaw and face) is shaped by signals generated by neural structures: brain and olfactory epithelium. Brain-derived Sonic Hedgehog (SHH) enables the induction of nasal septum and posterior nasal capsule, whereas the formation of a capsule roof is controlled by signals from the olfactory epithelium...

The endoscopic endonasal approach (EEA) provides direct access to foramen magnum meningiomas; however, it often requires extensive exposure including septal flap elevation with septum removal, complete sphenoidotomy, and panclivectomy.We present a case of a 54-yr-old-female with an incidental foramen magnum lesion followed up with serial imaging who presented 10 mo later with progressive neck discomfort and episodes of dizziness, with confirmed tumor progression and further brainstem compression. A focal transclival EEA with medial condylectomy was performed preserving the upper two-thirds of the clivus, the nasal septum, and the sphenoid sinus...

INTRODUCTION: The most common cause of septoplasty failure is inferior turbinate hypertrophy that is not treated properly. Several techniques have been described to date: total or partial turbinectomy, submucosal resection (surgical or with a microdebrider), with turbinate outfracture being some of those. OBJECTIVE: In this study, we compared the pre- and postoperative lower turbinate volumes using computed tomography in patients who had undergone septoplasty and compensatory lower turbinate turbinoplasty with those treated with outfracture and bipolar cauterization...

BACKGROUND: The endoscopic modified Lothrop procedure (EMLP) is commonly performed in recalcitrant frontal sinusitis, in part to achieve better penetration of medicated irrigations postoperatively. Although EMLP requires a septectomy for exposure, it is unknown whether septectomy size affects delivery of irrigations. In this study we evaluated the role of septectomy in delivery of irrigations to the EMLP cavity. METHODS: EMLP was performed on fresh human cadavers with sequentially increasing septectomy (minimal septectomy: drilling across septum to combine frontal sinuses; standard septectomy: 1...

Mucosal leishmaniasis (ML) is associated with progressive tissue destruction and granuloma formation, often after a considerable period of latency from an initial cutaneous infection. We report a case of recurrent epistaxis of 3 years duration and nasopharyngeal obstruction in a woman with treated cutaneous leishmaniasis nearly 30 years before and with no further exposure to Leishmania. Computed tomography revealed nasal septal perforation and histopathology demonstrated chronic inflammation. Microscopy was negative for amastigotes, but molecular testing of nasal mucosa biopsy detected Leishmania (Viannia) braziliensis ...

PURPOSE: Although nasal splints and trans-septal sutures are preferred for septal closure following septoplasty, quilting sutures, also known as continuous mattress sutures, are technically challenging and thus time consuming. Recently, the utility of a novel stitch device was demonstrated for quilting sutures; however, whether it contributes to the technical solution and time management of septal sutures remains unclear. This study aims to quantify the time and cost of septal closure following septoplasty by comparing nasal splints with quilting sutures using the septum stitch device...

INTRODUCTION: Complete circular endoscopic (submucosal) resection (CER) performed using the endoscopic submucosal dissection (ESD) technique is burdened with a high incidence of post-operative strictures in the esophagus. The most effective method of preventing them is not known so far; one of the possible methods is to prevent these strictures directly at the site of their formation by covering the defect with a stent. The aim of the study was to find a way to fix a selected biomaterial to a stent, and subsequently, to fix the stent at the CER site to prevent esophageal strictures in an animal model...

Although surrogate measures to quantify pain intensity have been commercialised, there is a need to develop a new index with improved accuracy. The aim of this study was to develop a new analgesic index using nasal photoplethysmography data. The specially designed sensor was placed between the columella and the nasal septum to acquire nasal photoplethysmography in surgical patients. Nasal photoplethysmography and Surgical Pleth Index® (GE Healthcare) data were obtained for 14 min both in the absence (pre-operatively) or presence (postoperatively) of pain in a group of surgical patients, each patient acting as their own control...

Rajshree Jayarajan
BACKGROUND: Nasal reconstruction is a common plastic surgery procedure following cancer resection. Whereas most small and medium defects are managed using standard local flaps, reconstructive options available for large defects of the nose such as a heminasal defect are very few. Most of the large defects are usually managed using a forehead flap, which involves at least 2 stages or using free tissue transfer. The author describes a combination flap that can be used for reconstruction of heminasal defects as well as lateral wall defects...
