Swinging inferior turbinate approach to the nasolacrimal duct

Background: Odontogenic maxillary cysts and tumours originate from the tooth root and have traditionally been treated through an intraoral approach. Here, we report the efficacy and utility of endoscopic modified medial maxillectomy (EMMM) for the treatment of odontogenic maxillary cysts and a tumour. Methodology: We undertook EMMM under general anaesthesia in six patients: four had radicular cysts, one had a dentigerous cyst, and one had a keratocystic odontogenic tumour. Results: The cysts and tumours were completely excised and the inferior turbinate and nasolacrimal duct were preserved in all patients. There were no peri- or postoperative complications, and no incidences of recurrence. Conclusion: Endoscopic modified medial maxillectomy appears to be an effective and safe technique for treating odontogenic cysts and tumours.

AbstractObjectiveTo evaluate the effectiveness and safety of a Hasner's valve incision performed under endoscopic intranasal surgery for the management of congenital nasolacrimal duct obstruction.MethodsThis retrospective study comprised 484 patients with congenital nasolacrimal duct obstruction who underwent incision of Hasner's valve under endoscopic intranasal surgery between April 2000 and October 2016. The primary endpoint was the procedure's functional success rate. The secondary endpoints were Hasner's valve and inferior turbinate anatomical findings, demographic data, complication rate and surgical duration.ResultsIn patients with no medical history of nasolacrimal duct probing, 91 per cent had a successful result, 5 per cent had a partially successful result, 3.9 per cent showed no change and 0.1 per cent had a worse result following the procedure. Concerning the secondary endpoints, outcomes were more frequently successful in children younger than three years. Only one patient had a post-operative infection. All patients underwent general anaesthesia; no complications related to general anaesthesia were observed. Mean surgical duration was 13.1 ± 5.7 minutes.ConclusionIncising Hasner's valve after medially displacing the inferior turbinate under nasal endoscopy seems to be an adequate primary surgical treatment for congenital nasolacrimal duct obstruction.

Objective. To review the prenatal development of the maxillary sinus under the perspective of the sinus surgery. Study Design. Cross-sectional study. Setting. Basic embryology laboratory. Subjects and Methods. Morphometry and morphology of the maxillary sinus and its ostium were studied under stereomicroscopy in 100 human fetuses from the 9th to the 37th week. Fetuses were obtained from the Fetal Collection of the School of Medicine of the Universidad Autónoma de Nuevo León. Approval was granted by the Ethics Committee. Statistics were applied. Results. The maxillary sinus begins its development at the 10th week. On the 37th week, the anterior-posterior diameter has a mean of 4.36 mm; ossification of the medial wall was absent, and the floor was located below the attachment of the inferior turbinate. Septa and recesses were temporarily observed. Some variations in shape were observed; however, only the oval shape persisted. Maxillary sinus hypoplasia was not found, although asymmetry was present in 30% of cases. The ostium was located at the anterior third of the ethmoid infundibulum; its final dimensions were 1.96 mm in length and 0.44 mm in width. The mean length between the ostium to the lamina papyracea and nasolacrimal duct was 1 mm. One case of double maxillary sinus was observed. Significant difference between the variables, in accordance with the age, was found ( P = .02). Conclusion. Knowledge of prenatal development of the maxillary sinus improves the perspective of the sinus surgeon and helps the understanding of postnatal anatomy, especially in children.

ABSTRACT Background Surgical importance of the nasolacrimal duct (NLD) for both otolaryngologists and ophthalmologists cannot be overemphasized. Injury to this structure can lead to iatrogenic epiphora, synechiae formation and need for secondary lacrimal diversion procedures. Materials and methods The present study was conducted on 27 mid-sagittal sections of head and neck of formalin fixed adult cadavers. The inferior opening of the NLD was identified and exposed. The duct and the lacrimal sac were dissected. Pertinent distances of the inferior opening of the NLD from the easily identifiable surgical landmarks were recorded, so as to accurately locate the inferior opening of the duct using a digital vernier calliper (accuracy 0.02 mm, Mitutoya, Japan). Various dimensions and angulation of the duct and lacrimal sac were measured. Results The average length of NLD was 11.42 ± 2.45 mm and it was making an angle of 20° with the vertical plane. The duct was narrowest in caliber in its upper 1/3rd in majority (82%) of the cases. The average diameter of the inferior opening of the NLD was 3.14 mm. In two cases (7.4%), the opening was only 1.8 mm wide. The mean distance of the inferior opening of the duct was 20.7 mm from the columella, 25.5 mm below the skull base and 16.5 mm above the hard palate. The average distance between the inferior opening of the NLD and anterior end of the inferior turbinate was 14.8 mm. The mean A-P diameter of superior opening of NLD was about 3 mm. The average length and width of nasolacrimal sac at its center was 6.95 and 3.24 mm respectively. Conclusion Detailed anatomical knowledge of the NLD is of great importance for safe and successful endonasal surgery. The present study attempts to provide useful surgical guidelines by using anatomic and positional relationships between the NLD and the major surrounding landmarks.

External Dcr

Dacryocystorhinostomy (DCR) is a bypass surgery in which an anastomosis is made between the medial wall of the lacrimal sac & the lateral wall of the nasal mucosa by cutting the intervening bone at the level of middle meatus to restore the flow of tears when the obstruction is beyond the common canaliculus. The only successful treatment of chronic dacryocystitis is DCR. The aim of this study was to evaluate the surgical intervention of conventional external DCR without silicon tube intubation. This prospective study was conducted at General Hospital, Faridpur from July 2012 to June 2014. Eighty cases with chronic dacryocystitis were selected for the study. We excluded the patients with lacrimal fistula, failed DCR and gross nasal pathology like deviated nasal septum, grossly hypertrophied inferior turbinate, atrophic rhinitis, nasal tumour, and polyp from our study. The patients' mean age at the time of surgery was 41.9±8.1 years ranged from 30 to 60 years. The operation was done under local anaesthesia by applying same technique. Then the patients were followed up for 12 months. In this study, we observed recurrence in five patients (6.25%) and complications from DCR are infrequent and not sight threatening. There were seven patients with reactionary haemorrhage, one wound infection, three wound gap, two epicanthal fold, one granuloma formation and five failed DCR. The success rate is 93.75% who underwent external DCR for the management of epiphora due to nasolacrimal duct obstruction.Faridpur Med. Coll. J. Jan 2015;10(1): 20-22
