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 94.4% in experienced hands and 58.0% in inexperienced hands. The endoscopic examination of six patients with failure in the first group revealed granulation tissue around the tube in four, atonic sac in one and persistence of bone that was supposed to have been excised in the nasal cavity in one. There were 21 failures out of 50 patients in the second group: granulation tissue in 2 cases, fenestration to the nasolacrimal duct instead of the sac in 6 cases, synechia between the lateral nasal wall and the middle turbinate in 2 cases, bony spicles causing obstruction in 5 cases and fenestration anterior to the sac in 2 cases. In 4 cases no reasons were found for failure, but perhaps the small fenestration and failure to remove the medial half of the membranous sac wall was the reason. DCR and STI can be performed for primary treatment in lacrimal obstruction. There is a learning curve for the operation. False localization of the lacrimal sac, granulation tissue formation around the tubes, retained bony spicles, inadequate removal of the medial wall of the sac and the synechia between the lateral wall and the middle turbinate are the most common causes of failure.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).

Nasal Pepsin Assay and pH Monitoring in Chronic Rhinosinusitis

Objectives/Hypothesis: The primary objective of this study was to determine the relationship between chronic rhinosinusitis (CRS) and laryngopharyngeal reflux (LPR). We also investigated the diagnostic value of pepsin in nasal lavage by means of fluorometric assay as compared with 24‐hour dual‐probe pH monitoring.

Body fat composition: a predictive factor for obstructive sleep apnea.

Objective: To investigate body fat composition, measured by bioelectrical impedance assay (BIA), for predicting the presence and severity of obstructive sleep apnea‐hypopnea syndrome (OSAHS). Body fat composition was also compared with other well‐known OSAHS predictors such as body mass index (BMI), neck circumference, and abdominal visceral fat.

Acute invasive fungal rhinosinusitis: our experience with 19 patients

Acute invasive fungal rhinosinusitis (AIFR) is a potentially fatal infection that affects immunocompromised patients. Early diagnosis and treatment, including aggressive surgical debridement, antifungal medication, and correction of underlying predisposing factors are essential for recovery. The aim of this study was to review our experience with AIFR. The records of 19 patients histopathologically diagnosed with invasive fungal rhinosinusitis were retrospectively reviewed. Demographic data, presenting symptoms and signs, underlying diseases, and outcomes of the patients are presented and invasive fungal rhinosinusitis is discussed in light of the current literature.

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 = 0.09), insignificant changes in PCO2, pH and HCO3 (P > 0.05), a significant increase in minimum and mean heart rates (P < 0.05) and insignificant changes in maximum heart rates; however, further research is necessary to elucidate the direct cause-and-effect relationship. No serious arrhythmias were observed. Although these changes may be within normal levels for healthy subjects, they may have serious consequences for patients with cardiopulmonary diseases.

Glass in the frontal sinus: report of three cases.

Patients with paranasal sinus foreign body are not commonly seen in otolaryngological practice; glass in the frontal sinus as a complication of maxillofacial trauma should be very rare, and papers dealing with this issue appear to be rare in the English literature. To elucidate the diagnostic pitfalls and the treatment aspects we present three cases of glass in the frontal sinus which occurred as a result of road traffic accidents.

Laryngeal pleomorphic rhabdomyosarcoma

Abstract 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. In contrast to other reported cases, the tumor in the present case had a very aggressive behavior. Despite radical surgery involving total laryngectomy and neck dissection followed by radiation therapy, the patient died of disease 8 months following treatment.

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. Serum levels of Zn in 6 patients were slightly lower than the normal limit. All the other serum levels of Zn, Cu and Mg were within the normal range. On the other hand, the mean serum level of Zn in the 37 patients was significantly lower than in a control group of 28 age and sex matched children. In contrast, the mean serum levels of Cu and Mg in the patients were significantly higher than in the control group. Whether this alteration in the trace element status causes or fosters recurrent and chronic tonsillitis is not clear.

A new transnasal approach to nasolabial cyst: endoscopic excision of nasolabial cyst.

Nasolabial cyst (NC) is one of the midface lesions that are seen rarely. Nasolabial cyst is generally seen in females typically on the fourth and fifth decades and localized unilaterally. Diagnosis usually depends on clinical evaluation. Sublabial excision is the classic method, but endoscopic marsupialization is suggested in current literature. An NC that is totally excised endoscopically is introduced in this article. This is the first case of NC excised endoscopically that is described in English literature.

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.
