Abstract
Abstract Purpose: Explore the effect of resection of different parts of
the maxilla on the prognosis of patients with nasal malignant tumors and
promote its clinical selection of nasal endoscopic maxillectomy.
Methods: The clinical data of patients with maxillary sinus tumors who
underwent endoscopic maxillary resection from January 2013 to May 2020
were analyzed retrospectively and the surgical methods, tumor margin,
recurrence and complications are summarized. Results: Among 30 patients
(all available follow-up; mean: 17.8 months, range: 2–64 months; pT:
T1–T4a), 17 (56.6%) underwent partial maxillary resection, nine
(30.0%) total resection, two (6.7%) subtotal resection and two (6.7%)
extended resection. There was no significant difference (Log Rank; P
> 0.05) in the recurrence rate between endoscopic-assisted
maxillectomy and trans-facial surgery. Conclusions: According to the
range of tumor lesions and the possible base, different parts of the
maxillary sinus can be removed selectively assisted by endoscopy. With
the application of endoscopic-assisted maxillectomy, the function can be
preserved as far as possible without increasing complications or
recurrence rate, and the surgical field of view will be exposed more
clearly.
