“…One of the authors (Lee-D.H.) reported that there was no interaction in the pneumatization of three PNSs (frontal, maxillary, and sphenoid) and mastoid air cells and that the growth of both was influenced by age in a pediatric population. [8] Karakas and Kavakli [11] reported that the volumes of PNSs and mastoid air cells increased with age and found a positive correlation between right-left and ipsilateral PNSs and mastoid air cells. Firat et al [9] evaluated the effect of NSD on ethmoid cell volume and determined whether there was any correlation between NSD grade and ethmoid cell volume in adult population.…”

“…These two openings are close enough to influence each other. [6,7] Lee et al [8] reported that no significant interaction existed between 3 PNSs (frontal, maxillary, and sphenoid) and mastoid air cell pneumatization in a pediatric population and that their size change had a significant linear regression relationship with age. They suggested that environmental factors could influence postnatal pneumatization of 3 PNSs and mastoid air cell pneumatization and that their effect was greater in MAC pneumatization.…”

OBJECTIVE:To evaluate the association between nasal septal deviation (NSD) and the volume of mastoid air cell pneumatization and compare it with the volume of maxillary sinus in a pediatric population. MATERIALS and METHODS:This retrospective cross-sectional study was conducted at a university-based, secondary referral hospital. Paranasal sinus CT imaging data of 59 children were reconstructed to the 3-dimensional model, and subsequently, we measured the volume of the maxillary sinus and mastoid air cell. On coronal images, nasal septal angle (NSA) and NSD/NC (nasal septal deviation/nasal cavity) ratio were measured. RESULTS:Mastoid air cell volume, as well as maxillary sinus volume, of the deviated side was smaller than that of the contralateral side, but these were not statistically significant. There was no correlation between NSA and volumes of mastoid air cell and the maxillary sinus. There also was no correlation between NSD/NC ratio and mastoid air cell and maxillary sinus volumes. Significant linear and growth regression was found between age and volume of the mastoid air cell and maxillary sinus but not between age and NSA and NSD/NC ratio. CONCLUSION:Mastoid air cell volume and maxillary sinus volume of the deviated side tended to be smaller than those of the contralateral side, which suggests that NSD can influence both aerations. However, because the degree of NSD did not correlate with the volumes of the mastoid air cell and maxillary sinus in this study, we should consider that further possible factors may be involved in both aerations.

“…Three-dimensional CT reconstruction of the paranasal sinuses (PNS) and the MACS in a pediatric population showed that the growths of both are influenced by age, but no interaction was observed between their volumes. 169 Mastoid development. Poor mastoid pneumatization is characteristic in patients with Down syndrome, regardless of the presence or absence of a history of TT insertion.…”

Objective. In this report, we review the recent literature (ie, past 4 years) to identify advances in our understanding of the middle ear-mastoid-eustachian tube system. We use this review to determine whether the short-term goals elaborated in the last report were achieved, and we propose updated goals to guide future otitis media research.Data Sources. PubMed, Web of Science, Medline.Review Methods. The panel topic was subdivided, and each contributor performed a literature search within the given time frame. The keywords searched included middle ear, eustachian tube, and mastoid for their intersection with anatomy, physiology, pathophysiology, and pathology. Preliminary reports from each panel member were consolidated and discussed when the panel met on June 11, 2015. At that meeting, the progress was evaluated and new short-term goals proposed.Conclusions. Progress was made on 13 of the 20 short-term goals proposed in 2011. Significant advances were made in the characterization of middle ear gas exchange pathways, modeling eustachian tube function, and preliminary testing of treatments for eustachian tube dysfunction.Implications for Practice. In the future, imaging technologies should be developed to noninvasively assess middle ear/eustachian tube structure and physiology with respect to their role in otitis media pathogenesis. The new data derived from these structure/function experiments should be integrated into computational models that can then be used to develop specific hypotheses concerning otitis media pathogenesis and persistence. Finally, rigorous studies on medical or surgical treatments for eustachian tube dysfunction should be undertaken.

“…It is well known that sinus anatomic development continues throughout childhood and into adulthood. 26 Likewise, it would be expected that the pathophysiology of PCRS also evolves throughout childhood into adulthood. The age at which the frontal sinuses (the last to fully develop) reach an adult size is approximately age 19.…”

Objective. To develop a clinical consensus statement on the optimal diagnosis and management of pediatric chronic rhinosinusitis (PCRS).Methods. A representative 9-member panel of otolaryngologists with no relevant conflicts of interest was assembled to consider opportunities to optimize the diagnosis and management of PCRS. A working definition of PCRS and the scope of pertinent otolaryngologic practice were first established. Patients of ages 6 months to 18 years without craniofacial syndromes or immunodeficiency were defined as the targeted population of interest. A modified Delphi method was then used to distill expert opinion into clinical statements that met a standardized definition of consensus.Results. After 2 iterative Delphi method surveys, 22 statements met the standardized definition of consensus while 12 statements did not. Four statements were omitted due to redundancy. The clinical statements were grouped into 4 categories for presentation and discussion: (1) definition and diagnosis of PCRS, (2) medical treatment of PCRS, (3) adenoiditis/adenoidectomy, and (4) endoscopic sinus surgery (ESS)/turbinoplasty.Conclusion. Expert panel consensus may provide helpful information for the otolaryngologist in the diagnosis and management of PCRS in uncomplicated pediatric patients.
