Interventions involving the middle meatus are commonly performed as majority of the paranasal sinuses open into the osteomeatal complex. The present study was therefore designed to provide information on maxillary ostium in relation to the important anatomical landmarks and also about the variations possible in the morphology of the middle meatus. Materials and methods: The present observational study was carried out on 25sagittal sections of head and neck in the department of Anatomy Kasturba Medical College, Manipal. The nasal septum was removed to visualize the lateral wall. The middle meatus was then studied for the variations possible in the openings of the bulla ethmoidalis and hiatus semilunaris. The distance of the maxillary ostium from the prominent landmarks was measured. The findings were recorded and tabulated. Results: The mean and standard deviations of the parameters were measured. The variations in the middle nasal concha and the bulla ethmoidalis were also observed. Conclusion: This knowledge about the variations in the lateral wall of the nasal cavity is crucial during the endoscopic interventions and for functional endoscopic sinus surgeries.

ABSTRACT Background: Chronic maxillary sinusitis is one of the common ENT problems. Accessory maxillary ostium (AMO) has been postulated in many publications to play a role in the development of chronic maxillary sinusitis. AMO is found in the medial wall of maxillary sinus and located in the lateral wall of the nose. It’s been frequently identified in the routine nasal endoscopy. The variations in the location of AMO have been evaluated by nasal endoscopy in live subjects or through cadaver dissections by many authors. This live study is conducted to identify the prevalence of AMO during nasal endoscopic evaluation of chronic sinusitis patients.

  • Lab Manual Axial Skeleton Atla
    1 PRE-LAB EXERCISES When studying the skeletal system, the bones are often sorted into two broad categories: the axial skeleton and the appendicular skeleton. This lab focuses on the axial skeleton, which consists of the bones that form the axis of the body. The axial skeleton includes bones in the skull, vertebrae, and thoracic cage, as well as the auditory ossicles and hyoid bone. In addition to learning about all the bones of the axial skeleton, it is also important to identify some significant bone markings. Bone markings can have many shapes, including holes, round or sharp projections, and shallow or deep valleys, among others. These markings on the bones serve many purposes, including forming attachments to other bones or muscles and allowing passage of a blood vessel or nerve. It is helpful to understand the meanings of some of the more common bone marking terms. Before we get started, look up the definitions of these common bone marking terms: Canal: Condyle: Facet: Fissure: Foramen: (see Module 10.18 Foramina of Skull) Fossa: Margin: Process: Throughout this exercise, you will notice bold terms. This is meant to focus your attention on these important words. Make sure you pay attention to any bold words and know how to explain their definitions and/or where they are located. Use the following modules to guide your exploration of the axial skeleton. As you explore these bones in Visible Body’s app, also locate the bones and bone markings on any available charts, models, or specimens. You may also find it helpful to palpate bones on yourself or make drawings of the bones with the bone markings labeled.

  • Investigations on the Growth Pattern of the Maxillary Sinus in Japanese Human Fetuses
    Okajimas Folia Anat. Jpn., 71(5): 311-318, December, 1994 Investigations on the Growth Pattern of the Maxillary Sinus in Japanese Human Fetuses By Thomas KOPPE, Toshio YAMAMOTO, Osamu TANAKA and Hiroshi NAGAI Department of Anatomy, Okayama University, School of Dentistry Department of Anatomy, First Division, Shimane Medical University -Received for Publication, August 31, 1994- Key Words: Pneumatization, Maxillary sinus, Growth, Human fetuses Summary: The growth pattern of the maxillary sinus was analyzed using 18 human fetuses of both sexes between 9 and 21 weeks of age postconception. The paraffin embedded specimens were cut in series in the frontal and the transversal plane, respectively. The inner surface of the maxillary sinuses was redrawn and surrounded with a digitizer and then the volumes were calculated. A correlation analysis as well as a simple linear regression analysis between the values of the maxillary sinus, different linear values of the nasal cavity and the crown-rump length (CRL) served to prove possible growth relations. The maxillary sinus' Anlage was already identifiable in the 29.8 mm (CRL) fetus. From this first appearance, the maxillary sinus expands not only in posterior direction but also in anterior direction from 11 weeks onwards. The maxillary sinus volume increased from 0.0008 mm3 at the age of 9 weeks to more than 9 mm3 at the age of 21 weeks. The results of the statistical analysis indicated, that the relationship between the maxillary sinus' Anlage and the nasal cavity were strongly influenced by the body size (CRL). This study suggests, that the growth of the maxillary sinus follows special regularities in the early fetal development.

  • Splanchnocranium
    splanchnocranium - Consists of part of skull that is derived from branchial arches - The facial bones are the bones of the anterior and lower human skull Bones Ethmoid bone Inferior nasal concha Lacrimal bone Maxilla Nasal bone Palatine bone Vomer Zygomatic bone Mandible Ethmoid bone The ethmoid is a single bone, which makes a significant contribution to the middle third of the face. It is located between the lateral wall of the nose and the medial wall of the orbit and forms parts of the nasal septum, roof and lateral wall of the nose, and a considerable part of the medial wall of the orbital cavity. In addition, the ethmoid makes a small contribution to the floor of the anterior cranial fossa. The ethmoid bone can be divided into four parts, the perpendicular plate, the cribriform plate and two ethmoidal labyrinths. Important landmarks include: • Perpendicular plate • Cribriform plate • Crista galli. • Ala. • Ethmoid labyrinths • Medial (nasal) surface. • Orbital plate. • Superior nasal concha. • Middle nasal concha. • Anterior ethmoidal air cells. • Middle ethmoidal air cells. • Posterior ethmoidal air cells.

Each consists of inferior and superior borders, medial and lateral surfaces, and anterior and posterior ends. The superior border serves to attach the bone to the lateral wall of the nose, articulating with four different bones.

Since there is little date on the mentioned topic, we aimed to carry out the presented study to obtain a volumetric index showing the relation between the nasal cavity and concha. Material and methods: The volumes of the nasal cavity and concha were measured in 30 males and 30 females (18–40 years old) on computed tomo- graphy images using stereological methods. Results: The mean volumes of nasal cavity, concha nasalis media, and concha nasalis inferior were 5.95 ± 0.10 cm3, 0.56 ± 0.22 cm3, and 1.45 ± 0.68 cm3; 7.01 ± 0.18 cm3, 0.67 ± 0.31 cm3 and 1.59 ± 0.98 cm3 in females and males, respectively. There were statistically significant differences in the volume of the nasal cavity and concha nasalis media (p < 0.05) between males and females, except for concha nasalis inferior (p > 0.05). Conclusions: Our results could provide volumetric indexes for the nasal cavity and concha, which could help the physician to manage surgical procedures related to the nasal cavity and concha.
