The comparison of the quality of life and intranasal edema between the patients with or without nasal packing after septoplasty.

Septoplasty is one of the most common operations performed in otolaryngology and anterior nasal packing is done routinely to prevent postoperative bleeding, septal hematoma or nasal synechia. Currently, transseptal sutures have gained a broader application area, not only for preventing the complications such as septal hematoma and bleeding but also closing any accidental tears of septal mucosa and providing additional support for the cartilage pieces retained in septoplasty. We evaluated the quality of life of the patients in early postoperative period (in the first postoperative week), intranasal edema with endoscopic examination and the intranasal changes with acoustic rhinometry.

The repair of cerebrospinal fluid rhinorrhea: comparison of histopathologic findings with cadaveric human temporal fascia, dura mater, and autologous fascia in a rabbit model.

Objectives: To evaluate the repair of cerebrospinal fluid rhinorrhea through the transnasal approach, we investigated histopathologic findings of grafting with human temporalis fascia and dura mater in a rabbit model.

Design And Methods: Thirty-two rabbits were assigned to three groups according to the graft material to be used: human dura mater, human temporalis fascia, and autologous muscle fascia (control group). The repair of the surgically induced bony opening was performed via the transnasal approach.

Asymptomatic looping of the internal carotid artery: a case report.

Variations and anomalies of the internal carotid artery in the neck are not rare. Although the possibility of these variations is well known, it may mislead the surgeon in certain circumstances as in the present case. A 68-year-old female patient had an asymptomatic looping of the internal carotid artery, which was recognized during neck dissection.

Giant malignant peripheral nerve sheath tumor of the neck in a patient with neurofibromatosis-1.

Sixteen-year-old mentally retarded male patient presented with a giant malignant peripheral nerve sheath tumor (MPNST) on his neck. Surgery was the chosen method of treatment by the help of a neurosurgeon for dissecting the mass from the nerves of the brachial plexus and a thoracic surgeon for removing the mass from the superior mediastinum. A mass of 2 kg in weight was excised gross totally.

Two consecutive cases of cerebrospinal fluid rhinorrhea after septoplasty operation.

Our aim in this work is to define the importance of anatomical knowledge in septoplasty operation and to prevent complications. Septoplasty is one of the most common operations in otorhinolaryngology to treat the nasal obstruction caused by septal deviation. During and after septoplasty, there are some recorded complications, such as hemorrhage, hematoma, septal abscess, septal perforation, saddle nose, infection, anosmia, visual disturbances, cavernous sinus thrombosis, meningitis, pneumoencephalos, subarachnoid hemorrhage, subdural empyma, brain abscess, periorbital emphysema, toxic shock syndrome, and cerebrospinal fluid (CSF) rhinorrhea.

[The value of endoscopy in the diagnosis of rhinolithiasis: a case report].

Diagnosis of rhinolithiasis may be difficult because of the possibility of varying clinical presentations. Complaints of a 34-year-old male patient had been misdiagnosed as sinusitis and several plain radiographs had missed the event. Endoscopic examination enabled a hard intranasal mass to be seen, resembling a rhinolith.

Endoscopic surgery in treatment of juvenile nasopharyngeal angiofibroma.

Objectives: Juvenile nasopharyngeal angiofibroma (JNA) is a highly vascular and locally invasive tumor with a high incidence of persistence and recurrence. The classical treatment of this tumor is surgery and/or radiotherapy. Use of endoscopic techniques seems to be on the rise in treatment of these lesions.

The effect on arterial blood gases and heart rate of bilateral nasal packing.

In order to elucidate the blood gas and heart rate changes caused by bilateral nasal packing, 21 healthy subjects who had had septoplasty or septorhinoplasty were investigated with pre- and post-operative blood gas measurements and 24-h Holter monitoring. Nasal packing caused a significant decrease in O2 saturation (P < 0.05), a borderline decrease in PO2 (P = 0.

Long-term results and reasons for failure of intranasal endoscopic dacryocystorhinostomy.

The aim of this study was to evaluate the long-term results and the factors influencing the success in patients with nasolacrimal duct obstruction treated with intranasal endoscopic dacryocystorhinostomy (DCR) and silicone tube intubation (STI). We prospectively investigated 158 patients with lacrimal obstruction in two groups, one of which comprised 108 patients treated primarily with intranasal endoscopic DCR by experienced surgeons and the other comprised 50 patients who were operated on by inexperienced surgeons. In a mean follow-up time of 49 months the surgical success was 94.

Subdural empyema and blindness due to cavernous sinus thrombosis in acute frontal sinusitis.

In this era of antibiotics, the complications of acute sinusitis are much less frequently encountered. Although orbital complications are most common, intracranial complications carry a high rate of mortality and morbidity. We describe a case of acute frontal sinusitis with subdural empyema and blindness due to cavernous sinus thrombosis and carotid artery thrombosis with a discussion of treatment of these complications and the etiology of blindness in sinusitis.

Laryngeal carcinoma and estrogen receptor analysis in patients after long-term follow-up.

Limitations in determining the progress and treatment of malignant diseases have prompted the investigation of new factors. Many molecules including estrogen receptors have been studied in an effort to understand the biological behavior of a tumor. To determine the effect of estrogen on laryngeal malignant cells, we analyzed the clinical findings of patients during long-term follow-up and compared these with the expression of estrogen receptors (ER).

Laryngeal pleomorphic rhabdomyosarcoma.

A case of an extremely unusual tumor of the larynx, pleomorphic rhabdomyosarcoma, is presented with a review of literature. This is the fifth case of this malignancy described in the larynx in the English language literature. A histopathological diagnosis was made with immunohistochemistry and electron microscopy.

Trace elements in children with chronic and recurrent tonsillitis.

Trace elements are indispensable for life and play a very important role in the essential functions. According to some reports in the literature lower trace element levels increase the susceptibility to recurrent infections. Since there are no reports available in the English literature about the effects of trace elements on recurrent and chronic tonsillitis, 37 children with recurrent and chronic tonsillitis were evaluated for Zn, Cu and Mg levels.
