Medial Maxillectomy

Inverted papilloma (IP) is a benign tumor of the nasal cavity and paranasal sinuses that is unilateral in most cases. Bilateral IP, involving both sides of the nasal cavity and sinuses, is extremely rare. This paper describes a large IP that filled in both sides of the nasal cavity and sinuses, mimicking association with malignancy. The tumor was successfully treated by bilateral endoscopic medial maxillectomy (EMM). The patient is without evidence of the disease 24 months after surgery. If preoperative diagnosis does not confirm the association with malignancy in IP, endoscopic sinus surgery (ESS) should be selected, and ESS, including EMM, is a good first choice of the treatment for IP.

Objectives: Neurilemmoma in the nasal cavity and paranasal sinuses is very rare. The study aimed to improve the understanding of neurilemmoma in the nasal cavity and paranasal sinuses. Materials and Methods: The clinical data of 10 patients with neurilemmoma in the nasal cavity and paranasal sinuses treated from January 2014 to June 2019 in our hospital were retrospectively studied. Results: There were 6 females and 4 males patients in our study. The mean age was 49.5 years (range 37-77 years), and the most common clinical symptom was unilateral nasal obstruction. The site of tumor included the nasal cavity, maxillary sinus, ethmoid sinus, and sphenoid sinus. There were 2 cases with malignant neurilemmoma. Nine patients underwent functional endoscopic sinus surgery (FESS); however, 1 patient underwent FESS combined with the lateral rhinotomy for complete resection of the tumor. Two patients with malignant neurilemmoma received postoperative radiotherapy. The mean follow-up was 3.82 years (range 2-7 years). There were no incidences of tumor recurrence during the study period. Conclusions: Neurilemmoma in the nasal cavity and paranasal sinuses is a mainly benign tumor. Complete surgical excision by FESS is the only treatment option for neurilemmoma in the nasal cavity and paranasal sinuses; while malignant neurilemmoma needs postoperative radiotherapy.

Endoscopic sinus surgery is a treatment method for chronic rhinosinusitis not controlled with medical treatment. It had started with functional endoscopic sinus surgery and the concept of reboot approach was introduced recently. For safe surgical treatment, understanding the anatomy especially personal variations between well-known structures is important. The practical points of surgical concept during endoscopic sinus surgery was suggested.

Before And After

AbstractBackground:Chronic rhinosinusitis is commonly treated by functional endoscopic sinus surgery involving excision of the uncinate process and opening of the osteomeatal complex.Methods:Computational fluid dynamics were used to compare nasal airflow after two different surgical interventions which involved opening the paranasal sinuses, excising the ethmoid sinus, and excising or preserving the uncinate process, in a cadaveric head model. Cross-sectional computed tomography images were obtained before and after the interventions. Imaging data were used to prepare computer simulations, which were used to assess the airflow characteristics of the nasal cavities and paranasal sinuses during inspiration and expiration, before and after intervention.Results:Significantly larger nasal cavity airflow velocity changes were apparent following the uncinate process excising procedure. Nasal cavity airflow distribution remained relatively unchanged following the uncinate process preserving procedure. There was a significantly greater increase in airflow volume following the uncinate process excising procedure, compared with the uncinate process preserving procedure.Conclusion:Preservation of the uncinate process may significantly reduce the alteration of nasal cavity airflow dynamics occurring after functional endoscopic sinus surgery for chronic rhinosinusitis.

(1) Background: The purpose of this study was to develop an image-guided endoscopic sinus surgery (IGESS) system, named Medigator®, based on the leave-one-out registration strategy and three-dimensional (3D) volumetric visualization of the nasal cavity and paranasal sinuses. (2) Methods: A phantom was designed and fabricated using a 3D printer. We then performed a phantom-based accuracy evaluation to validate the performance of the developed registration method. We included 11 patients who underwent IGESS for clinical study to compare the performance of the developed IGESS system with that of a commercialized system. (3) Results: The fiducial registration error (FRE) was 0.14 mm, and the target registration error (TRE) was 0.82 ± 0.50 mm by the phantom-based evaluation. As a result of the clinical comparative study, the average registration times were 36.04 ± 4.7 and 89.35 ± 26.1 s for the developed and commercialized systems, respectively (p < 0.05). The image loading time of the developed system was also shorter than that of the commercialized system (p < 0.05). The average accuracy score of the developed system was not significantly different from that of the commercialized system (p > 0.05). (4) Conclusions: The developed system provided an accurate point-to-point registration method based on the leave-one-out strategy. According to the results of the clinical comparative study, we demonstrated that the developed system showed reliable potential for clinical application.

Abstract Background Sinonasal inverted papilloma or Schneiderian papilloma is a rare benign tumor of paranasal sinuses and nasal cavities. It can cause bone remodeling and has a significant malignant potential. Hence, it is very important to diagnose and treat the tumor at the earliest. Recurrence can occur even after surgical extensive resection. Case presentation This case report highlights a case of a 36-year-old male patient who presented with right-sided reduced vision, nasal blockage, headache, and occasional blood-tinged nasal discharge. CT scan of paranasal sinuses revealed chronic sinonasal polyposis with secondary fungal colonization. MRI of the brain with orbit and PNS was suspicious for aggressive neoplastic disease with encasement of the cavernous sinuses and involvement of orbital fissure. The patient was operated for extended functional endoscopic sinus surgery. Histopathology revealed moderately differentiated invasive squamous cell carcinoma associated with Schneiderian (inverted) papilloma. Post-operatively, the patient received radiation for 4 weeks. Post-operative check nasal endoscopy was done 3 and 6 months after completion of radiotherapy which showed no evidence of recurrent disease with good healing and mucosalization of all the sinuses. Conclusions Sinonasal inverted papilloma, though a benign tumor, may turn malignant. Diagnosis is based on radiological investigations (in order to know the extent of the disease) and biopsy (to check if it is benign or additional malignancy present). Staging of the tumor helps in outlining the treatment protocol in each case. Post-surgery radiotherapy is indicated in cases where there is malignancy or complete resection of the tumor cannot be achieved. Meticulous follow-up of the post-operative patients is vital to check for recurrence.

Solitary fibrous tumor (SFT) is an uncommon neoplasm that usually arises from the pleura. To our knowledge, only 30 cases of SFTs in the nasal cavity and paranasal sinuses have been reported in the literature. We describe an SFT that arose from the right sphenoid sinus and extended to the nasal cavity and epipharynx. The tumor was completely removed by endoscopic sinus surgery without complication. The patient is taking an uneventful course without any evidence of recurrence of the disease 8 months after surgery now.

ABSTRACT Introduction An inverted papilloma is a benign tumor that is found in the nasal cavity or paranasal sinuses. Inverted papilloma accounts for approximately 0.5 to 2.0% of all nasal tumors. While it is considered benign, an inverted papilloma can destroy the surrounding bone. In a small number of cases (5-15%), an inverted papilloma may be found with a squamous cell carcinoma; one such case is reported. Case report A 70-year-old male presented with complaints of right-sided nasal blockage, which progressively increased over time and nasal discharge since one and half years with occasional history of epistaxis. On anterior rhinoscopic examination, there was a fleshy polypoidal mass filling the right nasal cavity. Contrast-enhanced computed tomography revealed a soft tissue density mass filling maxillary sinus and posterior choana with mild enhancement. Endoscopic medial maxillectomy was performed with complete removal of mass. Histopathological diagnosis was given as inverted sinonasal papilloma with malignant transformation. The patient was referred to a cancer reference center for treatment and received combined radiotherapy and chemotherapy. Patient was disease free at 6-month follow-up. Conclusion An inverted papilloma is a benign tumor with a propensity for malignant change. For these reasons, inverted papilloma should be treated like malignant tumor of the nasal cavity and paranasal sinuses. How to cite this article Prinja S, Davessar JL, Luthra H, Kaur M.

Background: Unilateral sinus disease (USD) occurs in 23 % of all cases. It is believed that it is mainly associated with cancer development. Retrospective data from large rhinological centers show that the most common USD is chronic rhinosinusitis (CRS), followed by mycosis, inverted papilloma and finally cancer, but only in a small percent of cases. The aim of the study: The analysis of USD in the group of patients who underwent FESS at the secondary referral center. Material and Method: The retrospective study of patients treated for USD in the Department of Otolaryngology in the Provincial Hospital in Poznan between June 2014 and June 2016. The analysis includes age, sex, the localization of lesions, histopathological and microbiological results, an extension of the surgery and treatment results. Results: Over the analyzed period of time, 415 FESS for chronic sinusitis were performed. In this group, 83 patients underwent surgery for USD. There were 35 women and 48 men.CRS was found in 48 cases, mycosis in nine cases, 12 patients were operated for non-malignant tumors, such as inverted papilloma (9), osteoma (2) and fibrosis tumor(1); seven patients had a choanal polyp and two of them had a foreign body in maxillary sinus – a tooth root lying loose. Four patients were diagnosed with a hypoplastic maxillary sinus and one patient suffered from frontal sinus pyocele. One side endoscopic opening of all sinuses was performed in the group with CRS, endoscopic medial maxillectomy was conducted in patients with inverted papilloma, and an isolated opening of the affected sinus was performed in the cases with mycosis. Conclusions: USD must be always suspected of malignant degeneration until proven otherwise. Endoscopic sinus surgery with the use of angled scope allows for the removal of even very extensive lesions. In our opinion, the extent of operation is determined by the nature of pathology. While extensive surgery is recommended in patients with inverted papilloma, a limited procedure should be performed in those with isolated mycosis.
