The Role of CD68 (+) Histiocytic Macrophages in Nasal Polyp Development.

 The aim of this study was to investigate the role of CD68 (+) histiocytic macrophages (H-M) in the nasal polyp pathogenesis.  The study group consisted of 24 adult patients with nasal polyposis. The control group consisted of 11 adult patients without nasal polyps.

Pleomorphic adenoma of the upper lip.

We present a rare case of pleomorphic adenoma in the upper lip region, with erosion of the maxillary bone and distortion of the facial appearance. A 20-year-old man presented with a painless mass on his upper lip, which had gradually increased in size over a period of 2 years. Computed tomography demonstrated a 30 mm × 28 mm enhancing mass in the upper lip region with no invasion to the surrounding tissues.

Can Oblique Sliced Method Avoid Warping?

Warping is the most important problem of costal cartilage grafts used in secondary rhinoplasties. The aim of this study is to show that costal cartilage grafts prepared with oblique sliced method (OSM), can solve the warping problem and provides successful results in both functional and aesthetic appearance. There are 42 patients who had previous nose surgery and dissatisfied with their facial appearance included in the study to perform secondary rhinoplasty with costal cartilage graft OSM technique.

Fascia lata: for the repairment of post-intubation tracheoesophageal fistula.

Tracheoesophageal fistulas are challenging formations for surgeons which can be treated with various surgical procedures. In an acquired tracheoesophageal fistula, fascia lata grafting can be accepted as a safe, easy accesible and a promising procedure, which can be one of the treatment options. We present a case of post-intubation tracheoesophageal fistula in which fascia lata was used as a reinforcement graft for the repairment in an adult patient.

Extrusion of Alloplastic Septal Silicone Implant: 25 Years After Rhinoplasty.

Multiple techniques and a variety of materials used for grafting have been described and applied over the years. Silicone implants are one of the most widely used alloplastic materials in Asian rhinoplasty, however, there are several complications. The authors report a case of an Asian woman who presented with implant rejection after 25 years later as a late complication of rhinoplasty.

Does intratympanic xylitol administration have ototoxic effects in a mouse ear model?

Objective: To research the ototoxicity of xylitol after intratympanic injection in mice ear model.

Methods: 24 female mice Balb/c mice (48 ears) included in the study. The mice were divided into 4 groups as 6 mice were found (12 ears) in each group.

Giant Epidermoid Cyst of the Maxillary Sinus: A Postoperative Complication?

Epidermoid cysts are benign lesions, which are usually detected on the floor of the mouth in the head and neck region. They can develop from abnormal epithelial components of an ectoderm tissue during the embryological life or alternatively they can arise from the implanted epithelium after trauma or surgery. The diagnosis of an epidermoid cyst in the maxillary sinus can be challenging and it could be easily mistaken for any benign or malign lesion of the nasal cavity and paranasal sinuses.

The role of MMP-2, MMP-9, and TIMP-1 in the pathogenesis of nasal polyps: Immunohistochemical assessment at eight different levels in the epithelial, subepithelial, and deep layers of the mucosa.

We conducted a prospective study to investigate the role of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), and tissue inhibitor of metalloproteinase-1 (TIMP-1) in the pathogenesis of nasal polyps. Our study group consisted of 24 patients-21 men and 3 women, aged 23 to 70 years (mean: 45.97 ± 11.

The role of platelet-derived growth factor in the pathogenesis of sinonasal polyps: immunohistochemical assessment in epithelial, subepithelial and deep layers of the mucosa.

Objectives: The aim of this study is to investigate the role of platelet-derived growth factor (PDGF) in the pathogenesis of sinonasal polyps.

Methods: Study group (groups 1-3) consisted of nasal polyp samples of patients with sinonasal polyps and the control group consisted of inferior turbinate samples of patients without nasal polyp. In group 1, 14 specimens from ethmoid sinus; in group 2, 10 specimens from nasal cavity; in group 3, 10 specimens from maxillary sinus; and in group 4 (control), 9 specimens from inferior turbinate were included.

A rapidly growing neck mass in childhood: Castleman's disease concomitant with cavernous lymphangioma in the posterior cervical region.

In this article, we present a 12-year-old girl case with a painless mass in the left posterior region of the neck for two weeks. Two masses were detected during surgery. Histopathologic examination revealed the hyaline vascular type of Castleman's disease for the bigger mass and cavernous lymphangioma for the smaller mass.

Uncinate process in the repair of nasoseptal perforation.

Septal perforation is an anatomical defect of the nasal septum. Prior septal surgery is the most common reason of this defect. Because repair of a nasoseptal perforation is a challenging surgical procedure, many techniques have been discussed for decades.
