<p class="abstract">Anatomic variations of the paranasal sinuses can lead to various diseases per se. The paranasal sinus anatomy should be carefully examined prior to performing endoscopic sinus surgery in terms of both existent pathologies and anatomic variations. The anatomy of the paranasal sinuses and its variations have gained importance, along with advances in coronal paranasal sinus computed tomography and extensive use of endoscopic sinus surgery. Rhinolith is a mass resulting from calcification of an endogenous or exogenous nidus within the nasal cavity. It is an uncommon disease that may present asymptomatically or cause symptoms like headache and nasal obstruction. A 24 year old woman was admitted in ENT department of GGS Medical College and Hospital, Faridkot with complaints of nasal obstruction, anosmia and headache persisting for 5 years. Right sided rhinolith was detected on anterior rhinoscopy. Bilateral concha bullosa with right sided rhinolith was reported on preoperative paranasal computed tomography scan. It is known that the paranasal sinuses have a number of anatomical variations. Sometimes severe anatomic variations predispose to rhinosinusitis. Herein we report a rare case, along with a review of the literature, to emphasize that severe anatomical variations should not be ignored.</p>

Abstract A thorough understanding of the sinonasal anatomy is required for the performance of a safe and successful surgery. With the aim to identify the variations in sinonasal anatomy in north Indian population twenty fresh cadaveric heads were dissected by messerklinger technique to identify various sinonasal anatomic variations in north Indian population. The variations in the key landmarks of nose and paranasal sinuses during endoscopic sinus surgery were noted and compared with other studies. Identification and differentiation of the normal and the abnormal sinonasal anatomic variations helps in preventing complications and giving optimum surgical results.

Background Recent developments in endoscopic sinus surgery (ESS) have increased the need to investigate the complex anatomic variations in the ethmoid roof and skull base, to inform the surgeon about the risk of damaging these crucial areas during ESS. Objective To offer a detailed description of sinus anatomy focusing on the key surgical landmarks in ESS and frontal recess surgery to standardize a systematic approach during the preoperative sinuses imaging evaluation. Methodology: A total of 220 computed tomography (CT) scans were reviewed to obtain six sets of measurements: the depth of the cribriform plate (CP); the length of the lateral lamella of the cribriform plate (LLCP); the angle formed by the LLCP and the continuation of the horizontal plane passing through the CP; the position of the anterior ethmoidal artery (AEA) at the skull base; the extent of frontal sinus pneumatization (FSP); the type of superior attachment of the uncinate process (SAUP). Results The length of the LLCP was statistically significantly correlated with the different Keros classification types, the angle formed by the LLCP with the continuation of the horizontal plane passing through the CP, and with the AEA position at the skull base. The depth of the olfactory fossa was correlated with FSP. Conclusions According to the Keros and Gera classifications, the data obtained from these evaluations allow the assessment of anatomic-radiological risk profiles and can help identify those patients who are high risk for ethmoid roof injury.

The aim of this study was to evaluate prevalence of chronic rhinosinusitis (CRS) and nasal polyps in adult patients with cystic fibrosis (CF) in Russian Federation. Additionally, we investigated the clinical course of CRS and developed the optimal therapeutic strategy.Methods. Three hundred and forty eight CF patients were involved in the study. Physical examination, computed tomography (CT) of paranasal sinuses and audiometry, if needed, were used. CRS and bilateral nasal polyps were diagnosed in 28 patients. Nasal endoscopy, SNOT-20 questionnaire, rhinomanometry, micro - biological examination of sputum and mucus from paranasal sinuses (obtained during puncture or surgery), spirometry, and measurement of serum markers of inflammation were used. Endoscopic sinus surgery was used in 14 patients (the group 1) and others were treated non-surgically (the group 2). Both group were treated during 6 months using intranasal mometasone, mucolytics and antibiotics via PARI SINUSTM nebulizer.Results. An improvement in symptoms, CT signs, rhinomanometry parameters and endoscopic signs was seen in both groups after treatment and was more prominent in the surgical treatment group compared to the non-surgical treatment group. Bacterial load reduction in nasal sinuses, decrease in the rate of pulmonary disease exacerbations, and an improvement in oxygen blood saturation were found in the surgical treatment group only. Treatment of CRS did not affect lung function, sputum microbiology and serum inflammatory markers.Conclusion. Endoscopic sinus surgery followed by intranasal mucolytics and antibacterials is an effective and well-tolerated treatment in adult CF patients with CRS.

Osteomeatal Complex

Six patients between the ages of 6 and 22 years old with cystic fibrosis were found to have mucoceles of the paranasal sinuses. Four were male and two were female. They experienced nasal obstruction, purulent rhinorrhea, and anosmia, but none had fever or pain. Nasal endoscopy and coronal computerized tomography scans revealed the lateral nasal wall to be displaced medially against the septum. Functional endoscopic sinus surgery revealed large cystic spaces filled with thick yellow-green mucus. Postoperatively most patients are able to smell and breathe through their noses. The mucocele probably begins as an obstructed anterior ethmoid cell, which then enlarges and obstructs the osteomeatal complex, which further impairs drainage of the other sinuses into this area.

Rare Phenomenon

Functional endoscopic sinus surgery (FESS) is most commonly used in chronic rhinosinusitis treatment. This method is also applicable to other diseases, including the treatment of symptomatic ectopic teeth. Ectopic teeth are a quite rare phenomenon. They may appear within the facial region, as well as in other parts of the body. The article describes two cases of ectopic teeth appearing within the nose area and paranasal sinuses, there endoscopic surgery has been used in the extraction, which resulted in the remission of symptoms.

Applied Anatomy

Serial sections of frozen cadaver heads were obtained in the axial, coronal, and sagittal planes. These were analyzed with specific attention to the anatomy of the paranasal sinuses as it pertains to endoscopic sinus surgery. Important anatomic landmarks are pointed out. The use of these landmarks to guide the surgeon through the dissection and to avoid complications is discussed. The resolution of chronic sinusitis is often brought about by the structural changes secondary to endoscopic sinus surgery, and the reasons for this outcome are reviewed.
