“…Dependent drainage through an inferior antrostomy may benefi t patients with disturbed mucociliary transport-for example, patients with cystic fi brosis. 7 Th e long-term eff ects of meatal antrostomy were discussed recently by Yanagisawa et al 7 Our study showed that intramaxillary sinus pressures along the nasal cavity-maxillary sinus exchange routes were greater when the patency of the natural ostia was augmented by counteropening. Th e pressures were better during rapid breathing than quiet breathing.…”

When conservative therapies are not eff ective in treating sinus infections, alternate steps can be taken to improve paranasal cavity ventilation. Th ese measures may include surgical procedures such as intranasal endoscopic or maxillary sinus fenestration, and other procedures such as placement of a maxillary sinus tube or a YAMIK sinus catheter. We conducted a prospective study of 25 patients to investigate the eff ects on the nasal mucosa of improved ventilation between the nasal and paranasal cavities. We accomplished this by comparing (1) the results of simultaneously measured nasal cavity and intramaxillary sinus pressures before and aft er widening of ventilation openings, (2) changes in mucociliary transport function as measured by the saccharin test, and (3) changes in nasal airway resistance. Just as multiple transit routes between the nasal cavity and maxillary sinus give rise to greater fl uctuations in intramaxillary sinus pressure, and just as rapid breathing gives rise to even greater pressure fl uctuations than does quiet breathing, we believe that both intranasal cavity airfl ow velocity and the number of ventilation openings present have an eff ect on the state of ventilation between the nasal cavity and maxillary sinus. We also suggest that the establishment of maxillary sinus ventilation openings improves mucociliary clearance.

“…Nevertheless, endoscopic approach via inferior meatal antrostomy has the advantage of inferior meatal naso-antral window that avoids violation of the ostiomeatal complex (OMC) and provides better access to anterior-inferior maxillary sinus lesions. Arguments against inferior meatal antrostomy include: persistent sinus disease following surgery, low patency rates, possible injury to the nasolacrimal duct or to developing canine teeth, and technical difficulties associated with the procedure [24,25]. While these arguments were substantial using anterior rhinoscopy approach, they are not valid with endoscopic approach in EIMA.…”

Antrochoanal polyp (ACP) is a benign unilateral polyp, originating from the maxillary sinus and expanding through the accessory or natural ostia into the nasal cavity and choanae. It has a 2: 1 male predominance and is more common in children and young adults. The exact pathophysiology is unclear, and it is thought to have less of the inflammatory reactions as opposed to typical bilateral nasal polyps which are commonly seen in diffused chronic rhinosinusitis. The presenting symptoms of ACP are unilateral nasal obstruction and rhinitis. Epistaxis, pain, and foul-smelling secretions are not typically seen and point towards a different etiology. Diagnosis is mainly clinical via endoscopic examination and supported by Computed tomography (CT) imaging. In CT images the three components of the polyp can be identified; an intramaxillary portion, intranasal and choanal components. Treatment is surgical, where Endoscopic sinus surgery (ESS) is the main technique used with other assisting approaches to reach the more challenging anterior and inferior areas of the maxillary sinus. Successful resection depends on complete removal of the intramaxillary component of the polyp to avoid polyp regrowth. The typical histologic characteristics are cyst formation, fibrosis and squamous metaplasia that are significantly more common in ACP than diffused nasal polyps.

Anatomical features of the opening of the nasolacrimal duct and the lacrimal fold (Hasner's valve) for intranasal surgery: A cadaveric study

The location and size of the opening of the nasolacrimal duct and the lacrimal fold (Hasner's valve) are variable. These features have clinical importance in nasal surgery because of the difficulty in determining their location. The aim of this study was to demonstrate the anatomical features of the opening of the nasolacrimal duct and the lacrimal fold and to discuss the importance of such knowledge in minimizing the risk of injury at surgery. Twenty sagittal head sections from formalin-fixed cadavers were examined. The sections showed no evidence of pathology or trauma. The type of opening of the nasolacrimal duct was a vertical sulcus in 14 of 20 (70%), an oblique sulcus in 2 of 20 (10%), an oblique fissure in 2 of 20 (10%), a vertical fissure in 1 of 20 (5%), and an anteroposterior fissure in 1 of 20 specimens (5%). The lacrimal fold was present in 16 of 20 specimens (80%). Five different forms of this fold were observed. Some morphological features were evaluated quantitatively. We believe that detailed anatomical knowledge of the opening of nasolacrimal duct will be useful in surgical approaches to this area.
