Near-infrared (NIR) Raman spectroscopy has been investigated as a tool to differentiate nasopharyngeal cancer (NPC) from normal nasopharyngeal tissue in an ex-vivo setting. Recently, we have miniaturized the fiber-optic Raman probe to investigate its utility in real time in-vivo surveillance of NPC patients. A posterior probability model using partial linear square (PLS) mathematical technique ...

BACKGROUND AND PURPOSE Primary chordoma in the nasal cavity and nasopharynx is an extremely rare tumor in the extraosseous axial skeleton. Unlike intracranial chordomas, lesions in these sites primarily present as a soft tissue mass without involvement of the skull base bone (clivus), so the preoperative diagnosis of the tumor is possibly difficult. Here, we reviewed the imaging features of 5 c...

OBJECTIVES The aim of the present systematic review was to assess the effect of functional appliances on the airway dimensions in patients with skeletal Class II malocclusion. MATERIALS AND METHODS Articles were identified through a literature survey carried out through the following databases: (1) PUBMED, (2) Google Scholar, (3) The Cochrane Library, (4) Embase, (5) Lilac, and (6) Web of Sch...

Warthin's tumor almost exclusively occurs in the parotid gland. It is the second most common tumor after the pleomorphic adenoma. The extraparotid or ectopic Warthin's tumor is rare and is normally situated in the submandibular gland, cervical lymph node, lip, cheek, tongue, hard palate, lacrimal gland and larynx. In this paper we present a case of the Warthin's tumor with ectopic localization ...

eratomas are neoplasms derived from germ cells with omponents of the three embryonic layers (ectoderm, mesoerm, and endoderm), that occur in any age group but re more prevalent in childhood, and have no gender reference.1,2 The lesions can be benign (mature, dermoid, nd cystic teratomas) or malignant (immature and solid tertomas), and can affect any structure in the midline).1--3 The linical pr...

BACKGROUND AND PURPOSE Chordoma is a relatively rare tumor of the skull base and sacrum thought to originate from embryonic remnants of the notochord. Chordomas arising from the skull base/clivus are typically locally aggressive with lytic bone destruction. When chordomas occur in an extraosseous location, they may mimic other lesions of the nasopharynx. We present 5 cases of primarily extraoss...
