The author has reported previously that the relation of the maxillary sinuses to rhinitis atroph.icans. Recently, the author studied the development of the maxillary bone with x-ray films and the relationship between the development of the maxillary bone and the occurrence of atrophic rhinitis was confirmed. Seventy cases of atrophic rhinitis were studied, both male and female patients rnging in age from 15 to 60. On the postero-anterior films the following distances were measured: a) From the median suture line of the palatinal plate to the external border of the maxillary bone. b) From is lateral wall of the inferior nasal meatus to the external border of the maxillary bone. c) From the inferior edge of the zygomatic arch to the inferior orbital margin.The statistical study of these measurements revealed that the maxillary bones in atrophic rhinitis were smaller than that in healthy subject. Embryologically, the inferior concha develops from the maxillary bone, therefore underdevelopment of the maxillary bone causes hypoplasia of the inferior nsaal concha, which is considered the most frequent cause of atrophic rhinitis. This type of atrophic rhinitis with limited development of the maxillary bone and the maxillary sinus, is considered to be constitutional.
