Maxillary air sinus opens in hiatus semilunaris of middle meatus of the nasal cavity. Drainage of sinus should happen through a natural orifice. That is mandatory because there are cases where there is an additional opening of sinus posterior to the hiatus semilunaris. In this case, there may be recirculation of mucus between natural and accessory opening leading to complications and recurrence of the patient’s problem during various endoscopic procedures. So noting this high significance of accessory opening, the present study was conducted. Total of 50 specimens (27 were from the right side, and 23 were from the left side) was studied. Presence of accessory opening of maxillary air sinus was noted. Position of the opening was noted. The shape of the opening was noted. The diameter of the accessory opening was measured using Sliding Vernier Caliper. Observations on the above parameters show the accessory opening of maxillary air sinus was present in 21 specimens out of a total of 50 specimens (42%). Typical Shape of the opening on the left side was Circular and on the right side was Oval. The average diameter of the opening on the right side was 24mm and on the left side was 46mm. So definitely significance of the accessory opening of maxillary air sinus was found. That’s why surgeons, especially, Otorhinolaryngologists, should note and explore the exact position of the accessory opening of maxillary air sinus, during various sinus surgeries.

ABSTRACT Myoepithelioma is a rare tumor of the salivary glands. Only three cases of myoepithelioma in the nasal cavity have been reported. A 29-year-old male presented to us with epistaxis and nasal obstruction. There was a fleshy mass occupying the right middle meatus. Biopsy showed evidence of myoepithelioma and an endoscopic excision of the tumor was done. Histopathological examination of the resected tumor was consistent with myoepithelioma. Due to its rarity, the nature of the tumor is not known and regular follow-ups are needed for early detection of recurrence and malignancy. How to cite this article Ramesh D, Khong GC, Sumathi V.

Leiomyoma is a benign tumor showing smooth muscle differentiation. Leiomyoma in the nasal cavity is a rare entity which can present with common nasal symptoms. We report a case of 19 years old male patient with nasal leiomyoma. The patient presented with recurrent episodes of nasal obstruction and epistaxis. On nasoendoscopy, there was a single grayish polypoidal mass in the right middle meatus which bled on touch. CT-scan of nose and paranasal sinus showed homogenous opacity indistinguishable from the right middle turbinate. The mass was excised endoscopically. There is no recurrence a year after the endoscopic excision of the nasal leiomyoma. Nasal leiomyoma carries a good prognosis after complete excision.Key words: endoscopic excision, leiomyoma, nasal cavity

Background. Concha bullosa (CB) is pneumatization of the middle turbinate and one of the most common anatomic variation of the sinonasal region. It is found in about 25% of the population. Middle meatus obstructive syndrome (MMOS) is, usually connected with CB. The main symptoms of this syndrome are headaches, impaired nasal breathing and hyposmia. Headache is the most common symptom and it may occur due to contact between a CB and other structures of the nasal cavity. Case report. We presented a case of 32 year-old-woman with headaches, located in the orbital and the left frontal region. The headaches were intermittent and corresponding to the nasal cycle. After neurologic and alergic examination, endoscopic nasal examination demonstrated a septal deviation to the right side and a large middle turbinate in the left side of the nasal cavity. Coronal computerized tomography (CT) of the paranasal sinuses demonstrated the septal deformation and pneumatization of the left middle turbinate. Diagnosis was confirmed by lidocaine test. In the functional endoscopic surgery (FESS), the lateral lamela of the anterior CB was removed. At the same time, the septoplasty was done. At the control examination, the patient was without symptoms. Conclusion. Although CB is the common anatomic variation of the nasal cavity, MMOS is rare. Headache (rhinogenic origin) is the most important symptom. Surgical treatment is the lateral resection of the CB in the FESS technique and the septoplasty.

From the Marine Parade, Tankerton, Whitstable, looking East, one obtains a capital view of Tankerton Bay, Swalecliffe, in which my discoveries have been made which are to form the subject matter of this paper. The grassy cliff at Priest and Sow corner at the end of the road stands at 55 O.D. This height gradually declining round the arc of the bay, to die out entirely in the Long Rock occupying the middle distance and through which the Swalecliffe Brook discharges into the sea. Just beyond, a little to the right, are the disused Swalecliffe Brick Works, with Stud Hill and Hampton lying further back. To the left and edging the horizon, Herne Bay Pier is clearly discernable. The accompanying copy of (Plate I.) the 25-in. Ordnance map of this Tankerton Bay section gives the exact position of the 650 yards from the Parish Boundary Stone eastwards indicated thereon with a X in which are found the gravels and brick-earths which have proved so rich in archaeological treasure trove. The whole of this south-easterly directioned well-drained gently sloping ground, from the Priest and Sow corner to the Swalecliffe brook, forms an ideal camping site. Last April a paper was read by me before the Geological Association, at University College, London, entitled “An Examination of the Contents of the Brick Earths and Gravels of Tankerton Bay, Swalecliffe, Kent,” in which the geological aspect of this section was fairly exhaustively treated, so that in this particular it will be unnecessary for me to do more than give a brief summary of the results of that examination as to the relative age and stratigraphical sequence of the Drift material found here overlying the London Clay.

The development of the lecithotrophic encapsulated larva of the internally-fertilizing, sublittoral gastropod Turritella communis Risso 1826 was documented using scanning electron microscopy and light microscopy. Encapsulated development was completed in 12 days at 15°C in the laboratory. Spawning occurred above ~10°C. Spawn masses consisted of numerous gelatinous egg capsules, each of which contained ~28 eggs, encased in albumen and fertilizing sperm. The eggs had an average diameter of 139 μm. Fertilization was accomplished by unpaired eupyrene sperm and occurred at the germinal vesicle stage. The developmental sequence followed the typical gastropod pattern, but was unique in a number of respects. Polar lobes were produced during meiotic maturation and early cleavage, with an especially large lobe occurring in association with the first cleavage, which was unequal. The blastula developed into a dorso-ventrally flattened placula at the 70-cell stage. Gastrulation occurred through invagination and epiboly acting together, and was uniquely accompanied by the development of ectodermal microvilli measuring ~ 1 μm in length. Extra-embryonic albumen began to be depleted after the development of the microvilli. It is proposed that the ciliated telotrochal cells gave rise to the pair of statocysts. Torsion was additionally observed to be facilitated by the growth of pre-mantle tissue on the right side and retardation of growth on the left side.

<p>Primary mucosal melanoma of the nasal cavity and paranasal sinuses is a very aggressive and rare disease with only about 0.5 % of malignant melanoma arising from the nasal cavity. There are only few reports from India. We report a rare case of sino-nasal mucosal malignant melanoma in a 58 years old female who presented with blackish coloured sino-nasal mass involving right nasal cavity, spontaneous and recurrent epistaxis and obliteration of the right naso-labial fold with occasional pain in the past 10 months. Contrast enhanced computed tomography scan showed a heterogenous mass involving right nasal cavity, right maxillary antrum and right ethmoidal area. A positron emission tomography computed tomography was also done which showed increased uptake in the region mentioned above. Initial biopsy, the mass was diagnosed as malignant melanoma. Total maxillectomy was performed with plan of post-operative radiotherapy.</p>

Background: Lymphomas are considered uncommon in goats, being the multicentric form with the highest number of cases for the species. Primary intranasal lymphomas are often diagnosed in dogs, cats, and humans. In the literature, there is only a description of a multicentric case involving the frontal sinuses and mucosa of the nasal cavity in a goat; therefore, it is important to describe unusual cases of this disease for the inclusion of new clinical and pathological characteristics in the ruminant clinic medicine. The objective of this work is to describe a case of T-cell lymphoma in the nasal cavity of a young goat.Case: The animal had dyspnea and respiratory noise for 15 days. Clinical examination showed nodulation in the right nasal cavity associated with serosanguinous secretion. Tracheostomy was performed; however, after 30 days the animal was euthanized. A sagittal plane of the head showed a pinkish-gray mass in the right and left nasal cavity, with a smooth, multilobulated surface, smooth adhering to the rostral portion of the dorsal concha and occluding the dorsal nasal meatus. Submandibular lymph nodes were slightly enlarged. Histopathological examination of the nasal cavity revealed a non-encapsulated, poorly delimited and ulcerated tumor composed of round cells arranged in a mantle supported by a discrete fibrovascular stroma extending the mucosa and lamina propria. Cells were round with sparse, eosinophilic and poorly delimited cytoplasm. Nuclei varied from round to elongated with condensed chromatin and evident nucleoli. Occasionally, aberrant nuclei, reniform shape and multinucleated cells were seen. Pleomorphism was moderate characterized by anisocytosis and anisocariosis. Typical and atypical mitosis were frequent (0-4 per field of highest magnification [400x]). Amidst the neoplasm, there were multifocal areas of necrosis and hemorrhage associated with a mild lymphocytic inflammatory infiltrate. Immunohistochemistry showed positive immunostaining for Vimentin antibodies and CD3, and negative for pan CK and CD20.Discussion: The lymphomas immunophenotyping is little used when it comes to farm animals, and there are few studies that use this technique for the definitive diagnosis of these neoplasms for small ruminants. The use of this technique must be considered in each case, in order to determine the pathogenesis, the accurate diagnosis and the origin of the neoplastic lymphocytes. In goats, T-cell lymphomas are the most diagnosed, although cases of multicentric B-cell lymphomas with ocular involvement have been diagnosed. In view of the clinical picture of the case described, infectious rhinitis already described in goats, such as aspergillosis and protothecosis, should be included as differential diagnoses. However, the anatomopathological findings facilitate the direction of the diagnosis, since infectious rhinitis presents as nodules / ulcerated masses or focal areas of necrosis associated with purulent secretion and in the histopathological examination it is possible to observe the intralesional etiological agents. In addition, the enzootic ethmoidal tumor must be included, as it has similar clinical signs and affects young animals, but they are adenomas/adenocarcinomas that affect the ethmoidal nasal shells induced by a retrovirus. Lymphomas in the caprine species are rare in the Northeastern semi-arid, but that in the present diagnostic routine occasionally occurs, being important the first description of its nasal shape for its inclusion in the differential diagnoses of diseases that present with clinical obstruction and dyspnea for the species.

<p class="abstract">Rhinolith or nasal stone is formed by mineralization within nasal cavity. They are calcareous concretions that are formed by the deposition of salts on an intranasal foreign body. It is an uncommon disease that may present asymptomatically or cause symptoms like nasal obstruction, consecutive sinusitis with or without purulent rhinitis, post nasal discharge, epistaxis, anosmia, nasal malodour and headache. They are usually diagnosed incidentally on radiographic examinations or depending on the symptoms. In this paper we report a 28-year-old woman admitted in the ENT department of GGS Medical College and Hospital, Faridkot with a calcified mass in the right nasal cavity causing long standing unilateral nasal obstruction for 3 years, rhinorrhoea (usually malodourous foetid), post nasal discharge and headache for 1 year. The calcified mass was thought to contain the air cell and removed by endonasal approach. The aim of this study is to report a case of rhinolith with chronic maxillary sinusitis along with a review of literature.</p>

Coronary artery variations are one of the commonest variations observed during clinical procedures. Normally, there are two main coronary arteries, the right coronary artery (RCA), left coronary artery (LCA).Left coronary artery gives two important branches left circumex artery (LCX) and left anterior descending (LAD) arteries. Knowledge about the coronary vessels and its variations are essential to clinicians to prevent untoward injury of vessels during any procedures. To study the morphology and variations of coronar Aim: y arteries by dissection. Materials and Methods: The present study was a cadaveric study which was conducted on 50 hearts obtained from adult human cadavers. Coronary arteries were dissected to see the origin, course and variations. The data was entered in Microsoft excel sheet and expressed in percentage. The Right Results: coronary artery branched out from the right aortic sinus and had an average diameter of 3.5mm. The left coronary artery arouse from left aortic sinus and had an average diameter of 4mm. LMCA divided into two branches in 60 percent, three branches in 30 percent and four branches in 06 percent of the hearts and direct branches from left aortic sinuus in 4 percent hearts.Based on the origin of Posterior descending or interventricular artery, Right dominance was observed in 68 percent, left dominance in 26 percent, and equal dominance in 06 percent of the hearts. Conclusion: Knowledge about the variations of coronary vessels is a prerequisite for clinicians to perform interventions of coronary vessels.

The nasal cavity is the entrance to the respiratory tract. Its functions are to clean, warm, and humidify air as it is inhaled. Respiratory mucosa covered by pseudostratified ciliated epithelium and goblet cells, as described in Chapter 5 and illustrated in Figure 5.2B, lines the majority of the nasal cavity. The cilia and mucus trap particles, thus cleaning the air; the mucus also humidifies the air and warming is achieved through heat exchange from blood in the very vascular mucosa. The efficiency of all these processes is increased by expanding the surface of the nasal cavity by folds of bone. The nasal cavity also houses the olfactory mucosa for the special sense of olfaction although the olfactory mucosa occupies a very small proportion of the surface of the nasal cavity. The nasal cavity extends from the nostrils on the lower aspect of the external nose to the two posterior nasal apertures between the medial pterygoid plates where it is in continuation with the nasopharynx. Bear in mind that in dried or model skulls, the nasal cavity is smaller from front to back and the anterior nasal apertures seem extremely large because the cartilaginous skeleton of the external nose is lost during preparation of dried skulls. As you can see in Figure 27.1 , the nasal cavity extends vertically from the cribriform plate of the ethmoid at about the level of the orbital roof above to the palate, separating it from the oral cavity below. Figure 27.1 also shows that the nasal cavity is relatively narrow from side to side, especially in its upper part between the two orbits and widens where it sits between the right and left sides of the upper jaw below the orbits. The nasal cavity is completely divided into right and left compartments by the nasal septum . From the anterior view seen in Figure 27.1 , you can see that the surface area of lateral walls of the nasal cavity are extended by the three folds of bone, the nasal conchae. The skeleton of the external nose shown in Figure 27.2 comprises the nasal bones, the upper and lower nasal cartilages, the septal cartilage, and the cartilaginous part of the nasal septum.
