“…Kennedy et al 13 reported that the widening of the natural ostium did not lead to stenosis in rabbits and suggested that unless the ostium is closed or stenotic, a widening of the ostium should not be performed. However, when there is severe inflammation of the maxillary sinus mucosa in humans, postoperative stenosis is often seen even after a middle meatal antrostomy encompassing the natural ostium, as noted in the reports by Davis et al 1 and Stankiewicz. 2 This raises a question about which part of the fontanelle would be ideal for making an antrostomy.…”

“…However, a 4.4% to 15% spontaneous closure rate for middle meatal antrostomy has been reported in the literature. 1,2 Furthermore, the spontaneous closure rate would be higher if we included the cases in which the surgical antrostomy opening became stenotic and returned to its original size or to an even smaller one. Because of these results, several methods for the maintenance of a surgical antrostomy opening or the creation of a larger antrostomy opening have been developed to increase the patency rate.…”

, DDS; J eung-Gweon Lee, MD; In-Hyuk Chung, MD Objectives: Although a complete anatomic knowledge of the fontanelle is a prerequisite to perform a surgical antrostomy opening, little is known about the boundary, shape, and size of the fontanelle. The purpose of this paper is to determine the best site for maintaining the patency of a surgical antrostomy opening by defining the anatomic boundaries, shape, and size of the fontanelle as well as its histological structure. Materials ana-Methods: One hundred sagittally divided heads were utilized. Mucosa overlying the lateral nasal wall was carefully removed with an operating microscope under 6x magnification. In some cases, a double mucous membrane, including the posteroinferior portion of the uncinate process, was cut as a whole and embedded in paraffin. The sections were stained with H&E. Results: The boundary of the fontanelle and the location of the. natural ostium were described in detail. Eight patterns of the posteroinferior portion of the uncinate process were observed. There were three major fontanelle shapes when observed from the medial aspect to the lateral: triangular, pencil-like, and oval. The triangular type was the most common. The anterior portion of the fontanelle was shorter than the posterior when ob· served medially and was wider than the posterior portion when observed inferiorly. Conclusions: The anterior portion of the fontanelle is more prone to stenosis than the posterior portion. An antrostomy in the posterior fontanelle may be more ideal for a mid· die meatal antrostomy of the maxillary sinus.

“…However, the phenomenon leading to this negative pressure is unclear. The lack of previous medical histories of chronic sinusitis, of the patients in these studies supports this concern: closure of the antrum is a common consequence of chronic sinusitis, and re-opening it is a classical treatment (Nigand, 1981;Davis et al, 1991). If closure of the antrum was the only cause of the imploding antrum syndrome, there should be a lot of imploding antrum syndromes among the patients with a chronic sinusitis.…”

“…[1][2][3][4] The basic tenets of ESS are opening and widening the obstructed sinus ostium, removing the irreversible damaged mucosa, and restoration of sinus drainage and ventilation. [1][2][3][4] Although the majority of maxillary sinus pathology can be removed through the middle meatus antrostomy (MMA), extensive mucosal disease can be difficult to handle, especially in the anterior and inferior regions. 5,6 In such conditions, occasionally the traditional Caldwell-Luc operation was elected.…”
