A Comparative Study of Antrochoanal Polyp in Children and Adults / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Antrochoanal polyp (ACP) is defned as a polyp that originates in the maxillary sinus. The polyps are usually seen in children and adolescents. The aim of this study was to compare the characteristics between the child and adults groups who have ACP. SUBJECTS AND METHOD: A total of 55 patients who underwent endoscopic sinus surgery for ACP was enrolled in this study. The population of this study was divided into child (≤17 years old) and adult (≥18 years old) groups. The clinical data and CT fndings including stages, maxillary sinus retention cyst (MSRC) of non-ACP lesion side, and accompanying sinusitis using Lund-Mackay score were retrospectively investigated. RESULTS: On CT stage of ACPs and MSRC, there were no signifcant differences between the two groups (p > 0.05). The accompanying sinusitis was more common in child group (p < 0.05). Endoscopic sinus surgery (ESS) combined canine fossa approach as well as ESS alone were the effective methods in treating ACPs in both groups. CONCLUSION: The accompanying sinusitis could be common in children with ACPs, which should be treated with ACPs simultaneously.

Pneumatization of the Frontal and Sphenoid Sinus in Korean Adults: A Study of Using Computed Tomography Scans / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: For safe sinus surgery, it is essential to understand the anatomical structure and developmental state of the paranasal sinuses. Structural abnormalies such as aplastic and marked hypoplastic sinuses may not be amenable to sinus surgery or balloon sinuplasty. The purpose of this study is to evaluate the degree of pneumatization of the frontal and sphenoid sinuses in Korean adults. SUBJECTS AND METHOD: This retrospective study utilized CT images of 1190 sides from 595 Korean adults. The frontal sinus was classified into normal, hypoplasia, aplasia and unilateral hidden aplasia. The sphenoid sinus was evaluated the incidence regarding the aplasia and unilateral hidden hypoplasia. RESULTS: Bilateral frontal sinus hypoplasia was observed in 8.5% of women and 4.2% of men (p 0.05). Bilateral frontal sinus aplasia was observed in 7.1% of women and 2.9% of men (p 0.05). Unilateral hidden frontal sinus aplasia was observed in 1.7% of women and 1.5% of men (p>0.05). There was no bilateral sphenoid sinus aplasia and only one woman had unilateral sphenoid sinus aplasia. Unilateral hidden sphenoid sinus hypoplasia was observed in 1.4% of women and 2.9% of men (p>0.05). CONCLUSION: Bilateral frontal sinus hypoplasia and aplasia are more common in women than in men. Although the incidences of unilateral hidden frontal sinus aplasia and hidden sphenoid sinus hypoplasia are low, sinus surgeons should carefully review CT for sinus surgery or balloon sinuplasty.
