Conclusions:
The midfacial degloving approach is a favorable option for advanced sinonasal inverted papilloma with a fair recurrence rate, and can replace the lateral rhinotomy approach, which is considered too invasive for benign tumor due to its facial scar.
Objective:
This study aimed to assess the treatment outcomes of advanced sinonasal inverted papillomas according to surgical approaches over a 20-year period.
Material And Methods:
We retrospectively reviewed clinic, operative, radiologic, and pathologic records of patients with surgically treated sinonasal inverted papilloma, and compared recurrence rates of patients treated with the endoscopic approach, midfacial degloving approach, and lateral rhinotomy approach in each Krouse stage of inverted papilloma.
Results:
A total of 114 patients were diagnosed and treated surgically for the sinonasal inverted papilloma. The follow-up period ranged from 10 months to 12 years (mean 2.8 years). The overall recurrence rate was 23.7% (27/114). Among the patients classified as Krouse stage III, 33.3% (9/27) of the endoscopic approach group, 11.1% (2/18) of the midfacial degloving approach group, and 25.0% (2/8) of the lateral rhinotomy approach group had recurrences.
Insights
The midfacial degloving approach offers a favorable outcome for advanced sinonasal inverted papilloma, showing a lower recurrence rate compared to other methods. This technique is a viable alternative to more invasive procedures.
Area of Science:
- Otolaryngology
- Head and Neck Surgery
- Oncology
Background:
- Sinonasal inverted papilloma (SNIP) is a benign tumor with a potential for recurrence and malignant transformation.
- Surgical management is the primary treatment modality for SNIP.
- Different surgical approaches exist, each with varying outcomes and morbidity.
Purpose of the Study:
- To evaluate and compare the treatment outcomes of advanced sinonasal inverted papillomas based on surgical approach.
- To assess recurrence rates across different surgical techniques over a 20-year period.
Main Methods:
- Retrospective review of clinic, operative, radiologic, and pathologic records of 114 patients with surgically treated SNIP.
- Comparison of recurrence rates between endoscopic, midfacial degloving, and lateral rhinotomy approaches, stratified by Krouse stage.
Main Results:
- The overall recurrence rate for SNIP was 23.7% (27/114) over a mean follow-up of 2.8 years.
- For Krouse stage III SNIP, recurrence rates were 33.3% (endoscopic), 11.1% (midfacial degloving), and 25.0% (lateral rhinotomy).
- The midfacial degloving approach demonstrated a lower recurrence rate in advanced stages.
Conclusions:
- The midfacial degloving approach is a favorable surgical option for advanced sinonasal inverted papilloma.
- This technique presents a lower recurrence rate compared to lateral rhinotomy, offering a less invasive alternative with comparable or better outcomes.
