Endoscopic dacryocystorhinostomy without stents.

OBJECTIVE: The aim of this study is to present our endoscopic DCR operation method without the use of silicone tubing and our results on the patients suffering from chronic epiphora with postsaccal stenosis. METHODS: Endoscopic dacryocystorhinostomy operations were performed to 21 sides of 18 patients who had chronic epiphora. No silicone tubing was used in any of the cases. In the postoperative healing period, the rhinostomy opening was maintained with frequent removal of nasal debris and using eyedrops. The patients were evaluated by fluoresceine test and endoscopic controls. RESULTS: Symptomatic improvement was achieved in 19 out of 21 sides of the patients (90.5%) and the results were confirmed by the fluoresceine test under endoscopic control. CONCLUSION: Our results of 21 sides of 18 cases underwent primary DCR without stents are as successful as those reported in the literature and the technique seems to be promising.

Evaluation of intraocular pressure and cataract formation following the long-term use of nasal corticosteroids.

It is possible that corticosteroids administered via nasal spray might reach ocular structures in levels sufficient to provoke an ocular hypertensive response and cause posterior subcapsular cataracts (PSCs) in susceptible individuals. In the present study, 26 patients who had undergone endoscopic sinus surgery were evaluated prospectively with respect to intraocular pressure and PSC formation following the use of nasal steroids for at least three months. Eighteen patients (69%) self-administered 200 micrograms/day of budesonide nasal spray twice daily, and eight patients (31%) self-administered 200 micrograms/day of beclomethasone dipropionate nasal spray twice daily, for a period of three to 19 months (mean 8.8 +/- 3.6 months). Ophthalmologic examination, tonometry, visual field testing and biomicroscopic studies revealed no evidence of ocular hypertension or PSCs during postoperative follow-up. We conclude that intranasal corticosteroids can be used safely for prolonged periods without increasing the risk of ocular hypertension or PSCs.

The evaluation of eustachian tube function in patients with chronic otitis media.

In this study we evaluated eustachian tube function in patients with chronic otitis media and compared the results with normal subjects. Two different eustachian tube function tests were applied to 60 ears of the chronic otitis media group and 146 ears of the control group. While eustachian tube dysfunction was observed in 71.7% of the chronic suppurative otitis media group, it was only seen in 34.9% of the control group.

Anatomical guidelines for intranasal surgery of the lacrimal drainage system.

To facilitate identification of the nasolacrimal duct during intranasal surgery, we have determined the distances between the lacrimal drainage system and certain anatomical structures on the lateral wall of the nasal cavity. A total of 15 adult cadaver skulls were bisected mid-sagittally and evaluated morphometrically. In our specimens, the average distance from the natural ostium of the maxillary sinus to the nasolacrimal duct (NLD) was only 5.5 mm. This rather small distance should be taken into consideration, in order to prevent trauma of the NLD during surgical enlargement of the ostium of the maxillary sinus. The distances from NLD to the anterior surface of the bulla ethmoidalis, the free edge of the uncinate process and the attachment point of the middle turbinate on the lateral nasal wall were found to be 10.2 mm, 8.8 mm and 5.4 mm, respectively. Taking these distances into account, easy identification of the NLD during endonasal dacryocystorhinostomy surgery will be possible.

Morphometric evaluation of paranasal sinuses for endoscopic sinus surgery.

Endoscopic surgical treatment of paranasal sinus infections is currently being applied in many Otorhinolaryngology Clinics. Although high rates of success are reported with this treatment method, life threatening complications sometimes do occur due to disorientation, especially when angled telescopes are used. In order to avoid such complications, we evaluated the distances from the anterior nasal spine to various important anatomic structures encountered during endoscopic surgery. The measurements obtained by a morphometric anatomic study of cadavers are presented in this study. We believe that if surgery is carried beyond the measured distances, serious complications may ensue during endoscopic surgery.

An endoscopic and tomographic evaluation of patients with sinusitis after endoscopic sinus surgery and Caldwell-Luc operation: a comparative study.

To evaluate the outcome of surgery using objective methods in patients with sinusitis after endoscopic sinus surgery (ESS) and Caldwell-Luc operation, we randomly selected 37 Caldwell-Luc-operated and 40 ESS-applied cases. Selected patient groups were assessed and compared by endoscopic examination and computed tomography (CT). CT was found to be normal in 12% of Caldwell-Luc-operated sides in comparison to 75% of ESS-applied sides. Endoscopy revealed a patency rate of the windows as 48% in Caldwell-Luc-operated and 86.7% in ESS-applied sides. Fibrosis and abnormal bony changes of the maxillary sinus were encountered in more than half of Caldwell-Luc-operated cases. In conclusion, ESS has a much higher rate of cure compared to the Caldwell-Luc operation if subjective and objective evaluation methods (CT and endoscopy) are applied.

Concha bullosa.

Concha bullosa is one of the most common, obstructive, anatomic variants seen in patients with sinusitis. In this study, a total of 160 patients with sinusitis were evaluated to study both the effects of concha bullosa on the distribution of opacification to the paranasal sinuses as well as the relations between the types of concha bullosa (CB) and ostiomeatal complex disease (OMCD). Our results show that CB does not necessarily have influence on the distribution of mucosal changes to paranasal sinuses. Furthermore, in the presence of OMCD, no significant difference statistically was found between patients with CB and those without. However, when the types of CB are considered, OMCD is found to be more frequent if the pneumatization is localized to the inferior half of the middle turbinate, such as in bulbous and extensive types of CB.
