Modified Medial Maxillectomy

For treatment of a sinonasal inverted papilloma (IP), it is essential to have a definite diagnosis, to identify its origin by computed tomography (CT) and magnetic resonance imaging (MRI), and to select the appropriate surgical approach based on the staging system proposed by Krouse. Recently, a new surgical approach named endoscopic modified medial maxillectomy (EMMM) was proposed. This approach can preserve the inferior turbinate and nasolacrimal duct. We successfully treated sinonasal IP with EMMM in a 71-year-old female patient. In this patient, the sinonasal IP originated from the entire circumference of the maxillary sinus. EMMM is not a difficult procedure and provides good visibility of the operative field. Lacrimation and empty nose syndrome do not occur postoperatively as the nasolacrimal duct and inferior turbinate are preserved. EMMM is considered to be a very favorable approach for treatment of sinonasal IP.

Background A staging system is essential for determining the optimal surgical approach and predicting postoperative outcomes for inverted papilloma (IP). Although staging systems based on the extent to which the location is occupied by an IP have been widely used, an origin site-based classification of IP using unsupervised machine learning algorithms has recently been reported. Objective To determine the most appropriate of five staging systems for sinonasal IP by comparing recurrence rates for each stage according to each of those systems. Methods Eighty-seven patients with sinonasal IP were enrolled in the study. Their tumors were retrospectively categorized according to the Krouse, Oikawa, Cannady, and Han staging systems, which are based on the extent of IP, and the Meng system, which is based on the site of origin. The rates of recurrence for each stage of the five systems were compared. Results Seven of the 87 patients (8.0%) had recurrences during an average 45.5 months (12–138 months) of follow-up. There were significant differences in disease-free survival between the stages specified by Han and Meng (p = 0.027 and p < 0.001, respectively), but not between the stages specified by Krouse, Oikawa, and Cannady (p = 0.236, 0.062, and 0.130, respectively). Cox proportional hazard models revealed that Meng system (adjusted hazard ratio [aHR] 4.32, 95% confidence interval [CI] 1.10–17.04) and presence of dysplasia (aHR 7.42, 95% CI 1.15–47.85) were significantly associated with recurrence. Conclusion The staging systems proposed by Han and Meng were found to be accurate in terms of tumor recurrence. We recommend use of the Han staging system before surgery and the Meng system after intraoperative identification of the origin of the tumor.

Risk Factors For Recurrence

Background and Objectives: Sinonasal inverted papilloma (IP) is a benign tumor with a locally aggressive nature and a propensity to recur. Many risk factors for recurrence have been reported, but they are still controversial. The aim of this study was to comprehensively assess the demographic data, clinical features, and potential risk factors for recurrence of IP.Subjects and Method: This work is a retrospective review of 382 patients diagnosed with and treated for sinonasal inverted papilloma between 1986 and 2017 at a single tertiary medical center. Demographic data, presence of associated malignancy, information about previous surgeries, tumor location, Krouse stage, surgical approach, follow-up duration, and data on recurrence were obtained.Results: In our study, 31 of 382 cases (8.1%) were associated with malignancy. Mean age was significantly higher in patients with associated malignancy compared to the benign IP group. Of the 351 benign cases, 263 (74.9%) were primary, and 88 (25.1%) were revision cases (residual or recurrent disease). Although the proportion of patients with high Krouse stage or multifocal involvement was high in the revision cases, there was no significant difference in recurrence rate. The 226 patients with a minimum follow-up of 1 year were included for recurrence analysis. Recurrence rate was significantly higher in the conventional surgery group (17.4%) compared to that of the endoscopic and combined surgery groups (8.1% and 3.6%, respectively). Also, the recurrence group showed significantly larger proportion of patients with high Krouse stage and multifocal involvement.Conclusion: Risk factors for recurrence of IP found in this study are comparable to those previously published. Generally, the factors associated with recurrence of IP were prior surgery, clinical stage, involved site, and surgical approach. Therefore, surgeons should always consider these risk factors to reduce the chance of recurrence.

Sinonasal Inverted Papilloma

AbstractBackground:Sinonasal inverted papilloma is a benign condition with the potential for recurrence and malignant change. Over the past few decades, numerous studies and reviews have addressed different aspects of this condition.Objective:To amalgamate the current literature on inverted papilloma, in order to review the evidence and consider the gaps in current knowledge.Methods:Retrospective, narrative review.Results:The reported incidence of inverted papilloma varies between centres and is affected by selection bias. The exact aetiology of inverted papilloma is not fully understood. Currently, there is no reliable histological or biological marker to predict the probability of recurrence or malignant transformation. There is no universally accepted staging system available for sinonasal inverted papilloma. Complete surgical removal of the tumour is the mainstay of treatment, but the method of choice depends on the extent of the disease, the skill of the surgeon and the technology available.Conclusion:In order to compare different studies and to enable meta-analysis of the literature, there should be a universally accepted staging and classification system for sinonasal inverted papilloma. Further research on the aetiology of sinonasal inverted papilloma, and on biological markers for its recurrence and malignant transformation, is required. To enable meaningful future research, we would encourage multicentre participation with a consensus on management.
