Introduction: The variation in the course of infraorbital canal and protrusion of the infraorbital nerve through it to the maxillary sinus may lead to its accidental injury during reconstructive or endoscopic sinus surgery. Preoperative identification of this variant will prevent unintended injuries. Methods: A retrospective study of 307 patients who underwent CT scan study of the paranasal sinuses at Chitwan Medical College, Nepal was conducted. The protrusion of infraorbital nerve to the maxillary sinus was identified and the length of the bony septum along with the infraorbital nerve was measured. It was further classified as Class I to III according to the length of the septum.Results: The prevalence of protrusion of inferior orbital nerve in our study was 11.40 % and bilateral protrusion was 5.8 %.  The median length of the protruding component along with the septum was 4.9 mm. Conclusion: Preoperative identification of the normal protrusion of infraorbital nerve to the maxillary sinus will prevent accidental injuries during sinus surgery. CT scan of the paranasal sinus would be the modality of choice for identification of this variant.

Root Canal Irrigation

Introduction The frequently used irrigant in dental surgery, sodium hypochlorite, is occasionally the cause of minor, usually circumscribed, adverse effects. Severe, extensive complications, with lasting sequelae, however, also can occur, as in the case we report herein. Case Report A 55-year-old woman underwent an endodontic procedure on a maxillary molar, whose roots, unknown to the surgeon, were protruding into the maxillary sinus. After sodium hypochlorite root canal irrigation, the patient immediately developed intense facial pain, facial edema, and periorbital cellulitis. An emergency department evaluation diagnosed an intense inflammatory disease of the maxillary sinus, with significant destruction of its bony walls, accompanied by midface paraesthesia due to infraorbital nerve injury. In the following weeks, the patient slowly developed enophthalmos due to bone erosion of the orbit floor. Treatment, besides prolonged oral steroids, required the endoscopic endonasal opening of the maxillary sinus for profuse irrigation. Two years later, the patient maintained a complete loss of function of the maxillary sinus, anesthesia-paraesthesia of the midface, and inferior dystonia of the eye with an enophthalmos. Conclusion Dentists, maxillofacial surgeons, and otorhinolaryngologists should all be aware of the whole spectrum of complications of even the simplest dental work. Sodium hypochlorite irrigations should be used cautiously in root canal surgery, with the full awareness of its potential for causing soft-tissue damage.

The fungal ball is the most common clinical form of fungal etiology sinusitis. The main method of treatment of patients with this pathology is surgery. Achieving complete removal of the fungal body is important, especially in patients who will have planned dental implantation. Among the accesses to the maxillary sinus in cases of the fungal body of the sinus, the most common one is through the middle meatus, but it does not provide visual control of the anterior parts of the sinus during the intervention. The use of modified infraturbinal access provides better opportunities for examination of the anterior parts of the maxillary sinus. The purpose of the study is to increase the effectiveness of surgical treatment of patients with fungal bodies of the maxillary sinus by optimizing access during endoscopic endonasal intervention. Materials and methods. The data of 113 patients with fungal ball of maxillary sinuses who underwent sinusotomy in preparation for dental implantation were analyzed. Cone beam computed tomography of paranasal sinuses of patients were performed twice – before functional endoscopic sinus surgery and before subantral augmentation of the maxillary bone. Group 1 included 78 patients to whom the fungal balls were removed from the sinus through the middle nasal meatus, group 2 – 35 patients to whom, in cases when it was impossible to visually confirm the completeness of removal of the fungal ball from the anterior area of the sinus, an additional infraturbinal approach was performed in our modification. Results and discussion. According to tomography before rhinosurgery it was established that "blackout" of more than 60% of the sinus space is observed in 50.5% of patients with fungal bodies, with the vast majority of patients (88.1%) fungal bodies in the maxillary sinus are located in its lower parts and spread forward from the nasolacrimal canal level. During sinus rehabilitation, the need for additional infraturbinal access arose in 5 (14.3%) patients of the second group. As a result of its performance in all 5 operated patients polyposis-altered tissues were found in "blind zones" and in 2 (5.7%) – there were also remains of a fungal body. Residual fungal bodies in the maxillary sinus were detected in 3 (3.9% CI 95% – 0.01; 11.6) patients of the first group, and were not observed in the second group. All cases of residual fungal masses in the sinus were not accompanied by specific complaints. A revision of sinusitis with fungal masses removing was performed on 3 patients due to the appearance of residual fungal bodies by preformed antrostomy with local anesthesia. Conclusion. Anthrostomy using additional endoscopic infraturbinal access when removing the fungal body from the lower anterior maxillary sinus is the optimal combined access that allows maximum visualization of the maxillary sinus and avoid recurrence of the disease

Importance: Safe entry into sphenoid sinus is critical in endoscopic sinus and skull base surgery. A number of surgical landmarks have been used to identify the sphenoid sinus ostium during endoscopic endonasal surgery with variable reliability and intraoperative feasibility. Objective: To determine if the posterior wall of the maxillary sinus is a reliable landmark to determine the depth of the sphenoid sinus ostium during anterior to posterior dissection. Design, Setting, and Participants: Prospective study of adult patients undergoing endoscopic sinus surgery between August 2016 and September 2017. Measurements were made intraoperatively between the depth of the posterior maxillary sinus wall and sphenoid sinus ostium. Main Outcomes and Measures: The primary measurement is the distance between the depth of the posterior maxillary sinus wall and sphenoid sinus ostium. Additional data points included age, gender, surgical indication, and primary versus revision endoscopic sinus surgery. Results: Forty-five patients (38% male, 62% female) with an average age of 56 were enrolled, resulting in 88 operated sides. The average distance between the depth of the posterior wall of the maxillary sinus and the sphenoid ostium was 1.5 mm ± 1.4 mm. The most common position of the sphenoid sinus ostium was posterior to the level of the posterior maxillary sinus wall (54%), followed by same level (23%) and anterior (23%). There was no significant difference between different disease states ( P = .75) and between primary and revision cases ( P = .13). Conclusions and Relevance: The posterior wall of the maxillary sinus serves as an adjunctive intraoperative landmark to determine the depth of the sphenoid sinus ostium. While the posterior wall of the maxillary sinus approximates the depth of the sphenoid sinus ostium, the relative position is variable and can be anterior or posterior.
