Purpose:
This large retrospective, single-center, follow-up study investigated the endoscopic prelacrimal recess approach (PLRA) for treating maxillary sinus inverted papilloma (MSIP).
Methods:
Between January 2007 and November 2022, patients with MSIP treated with PLRA were enrolled. Data on clinical manifestations, imaging, and surgical procedures were collected. The visual analog scale (VAS) scores for maxillofacial numbness and nasal symptoms and the SNOT-22 nasal symptom scores were statistically analyzed.
Result:
Of 122 patients (68 males and 54 females) enrolled in the study, with a mean age of 50.75 ± 12.84 years (26-80 years), 111 patients underwent PLRA, nine underwent modified PLRA, one converted to an endoscopic medial maxillectomy (EMM), and one to an endoscopic modified Denker's approach. The average follow-up was 86.60 (13-192) months, the recurrence rate was 3.28%, and 29 patients (23.77%) complained of maxillofacial numbness one month postoperatively, which disappeared in most cases one year after surgery. Five patients (4.10%) experienced mild numbness at the end of the follow-up period. Maxillary sinus ostium contracture or atresia occurred in two cases (1.64%). After surgery, the VAS nasal symptom scores improved significantly (P < 0.001). SNOT-22 indicated that the most common postoperative symptom was thick nasal discharge.
Conclusion:
PLRA is a flexible first-choice surgical treatment for maxillary sinus inverted papilloma and can be modified according to the extent of the lesion, the surgeon's experience and technique, and surgical instruments. That can help achieve complete resection and reduce recurrence and surgical complications. Upper teeth numbness, the most common postoperative complication, tends to disappear after 1 year.
Insights
The endoscopic prelacrimal recess approach (PLRA) is an effective treatment for maxillary sinus inverted papilloma (MSIP), offering low recurrence rates and manageable complications. Most post-operative numbness resolves within a year.
Area of Science:
- Otolaryngology
- Neurosurgery
- Surgical Oncology
Background:
- Maxillary sinus inverted papilloma (MSIP) is a benign but locally aggressive tumor.
- Traditional surgical approaches can be associated with significant morbidity.
- The endoscopic prelacrimal recess approach (PLRA) has emerged as a minimally invasive alternative.
Purpose of the Study:
- To evaluate the efficacy and safety of the endoscopic prelacrimal recess approach (PLRA) for treating maxillary sinus inverted papilloma (MSIP).
- To assess post-operative outcomes, including recurrence rates and complications such as numbness.
Main Methods:
- A retrospective analysis of 122 patients with MSIP treated with PLRA between January 2007 and November 2022.
- Data collected included clinical, imaging, and surgical details.
- Patient-reported outcomes using Visual Analog Scale (VAS) for numbness and nasal symptoms, and Sino-Nasal Outcome Test-22 (SNOT-22) were analyzed.
Main Results:
- The study included 122 patients with a mean age of 50.75 years.
- The overall recurrence rate was 3.28% over an average follow-up of 86.60 months.
- Postoperative numbness, primarily affecting the upper teeth, occurred in 23.77% of patients at one month but resolved in most by one year. Significant improvement in nasal symptoms (VAS and SNOT-22) was observed (P < 0.001).
Conclusions:
- The endoscopic prelacrimal recess approach (PLRA) is a versatile and effective first-line surgical treatment for MSIP.
- PLRA can be modified to accommodate lesion extent and surgeon preference, facilitating complete resection and minimizing complications.
- Upper teeth numbness is the most common complication, typically resolving within a year, making PLRA a favorable option for MSIP management.
