Endoscopic Approach to Organized Hematoma of Maxillary Sinus Using the Swinging Technique of Nasolacrimal Duct and Inferior Turbinate

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 Introduction The endoscopic access has reduced the morbidity associated with external approaches in diseases of the maxillary sinus. A reversible endoscopic medial maxillectomy (REMM) is presented as an alternative for treatment of benign maxillary diseases. Objective To describe the REMM technique and report four cases of patients with benign maxillary sinus conditions treated through this approach. Methods The present study was divided into two parts: anatomical and case series. Two cadaveric dissections confirmed the feasibility of the REMM approach. The same technique was performed on four consecutive patients with benign maxillary sinus disease. Results The cadaveric dissections confirmed wide exposure to the maxillary cavity, preserving the anatomy of the maxillary sinus. In the patient series, one patient presented with an antrochoanal polyp, one had a silent sinus syndrome, one had a chronic maxillary sinusitis secondary to a gunshot, and the last one had an inverted papilloma in the maxillary sinus. In all of the cases, the REMM approach provided excellent access and adequate resection, as well as preservation of the inferior turbinate, nasolacrimal duct, and lateral wall of the nose (including its osteomucosal component). Finally, all of the patients had an uneventful postoperative course. Conclusion The REMM technique is an excellent surgical approach to benign conditions of the maxillary sinus. It has few limitations and appears to be associated with less morbidity than conventional techniques.

Modified Medial Maxillectomy

For treatment of a sinonasal inverted papilloma (IP), it is essential to have a definite diagnosis, to identify its origin by computed tomography (CT) and magnetic resonance imaging (MRI), and to select the appropriate surgical approach based on the staging system proposed by Krouse. Recently, a new surgical approach named endoscopic modified medial maxillectomy (EMMM) was proposed. This approach can preserve the inferior turbinate and nasolacrimal duct. We successfully treated sinonasal IP with EMMM in a 71-year-old female patient. In this patient, the sinonasal IP originated from the entire circumference of the maxillary sinus. EMMM is not a difficult procedure and provides good visibility of the operative field. Lacrimation and empty nose syndrome do not occur postoperatively as the nasolacrimal duct and inferior turbinate are preserved. EMMM is considered to be a very favorable approach for treatment of sinonasal IP.

Abstract Introduction The endoscopic access to lesions in the anterolateral wall of the maxillary sinus is a challenging issue; therefore, the evaluation of access should be performed. Objective To assess the accessibility of three endoscopic ipsilateral endonasal corridors. Methods Three corridors were created in each of the 30 maxillary sinuses from 19 head cadavers. Accessing the anterolateral wall of the maxillary sinus was documented with a straight stereotactic navigator probe at the level of the nasal floor and of the axilla of the inferior turbinate. Results At level of the nasal floor, the prelacrimal approach, the modified endoscopic Denker approach, and the endoscopic Denker approach allowed mean radial access to the anterolateral maxillary sinus wall of 42.6 ± 7.3 (95% confidence interval [CI]: 39.9–45.3), 56.0 ± 6.1 (95%CI: 53.7–58.3), and 60.1 ± 6.2 (95%CI: 57.8–62.4), respectively. Furthermore, these approaches provided more lateral access to the maxillary sinus at the level of the axilla of the inferior turbinate, with mean radial access of 45.8 ± 6.9 (95%CI: 43.3–48.4) for the prelacrimal approach, 59.8 ± 4.7 (95% CI:58.1–61.6) for the modified endoscopic Denker approach, and 63.6 ± 5.5 (95%CI: 61.6–65.7) for the endoscopic Denker approach. The mean radial access in each corridor, either at the level of the nasal floor or the axilla of the inferior turbinate, showed a statistically significant difference in all comparison approaches (p < 0.05). Conclusions The prelacrimal approach provided a narrow radial access, which allows access to anteromedial lesions of the maxillary sinus, whereas the modified endoscopic Denker and the endoscopic Denker approaches provided more lateral radial access and improved operational feasibility on far anterolateral maxillary sinus lesions.

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.
