A Modification in Extirpation of the Lacrimal Sac
نویسنده
چکیده
Most methods of removing the lacrymal sac follow closely the operation devised by Kuhnt and fully described by him in his classical monograph in the Klinisches Jahrbuch (" Ulber die Therapic der Conjunctivitis Granulosa" Yon Dr. MedHermann Kuhnt, Yol. VI, 1897). Kuhnt, who in 1888 had extirpated over 500 sacs by this method, gave Platner (1724), the credit of being the first to perform extirpation and says he combined it with a drilling through the os unguis into the nose so that the tears could escape into the nose. This addition has recently again been advocated.

A SURVEY OF 200 DCR OPERATIONS
In a prospective survey, 200 cases of operated chronic dacryocystitis were divided into three groups according to the kind of operation, and the respective results are as follows: Group I includes 100 cases in whom the lacrimal bone was removed (8mm x 8mm) and a 6mm diameter catheter was used (as a duct between the lacrimal sac and nasal cavity). The recurrence rate within one year was 24 ...

Introduction: Dacryocystorhinostomy (DCR), a popular surgical procedure, has been performed using an endoscopic approach over recent years. Excellent anatomical knowledge is required for this endoscopic surgical approach. This study was performed in order to better evaluate the anatomical features of the lacrimal apparatus from cadavers in the Isfahan forensic center as a sample of the Iranian ...

متن کاملDifferent approach to the lacrimal sac area.
THE USUAL approach to the lacrimal sac and the area around is through the standard curved incision, with the centre of the concavity about 2-3 mm. from the inner margin of the inner canthus. It can be termed "adequate", although, to get a good view and to have freedom of manoeuvre, the incision has often to be widely stretched in all directions. Even then, one is often working in a fairly deep ...
متن کاملEvaluation of the canalicular entrance into the lacrimal sac: an anatomical study.
PURPOSE The purpose of this study was to investigate the prevalence of a common canalicular entrance in the lacrimal sac and to investigate the anatomy of the canalicular/lacrimal sac junction with direct visualization using a novel cadaveric dissection technique. METHODS Preserved cadavers were dissected to allow direct visualization of the canalicular entrance(s) to the lumen of the lacrima...
