Right uncinectomy, right antrostomy
and right anterior ethmoidectomy were done.
We performed bilateral ethmoidectomy and right-sided middle meatal antrostomy
and found that the right maxillary sinus was filled with mucopurulent secretions.
Uncinectomy and middle meatal antrostomy
was performed in all cases.
Powered endoscopic maxillary antrostomy
was described in detail (7) and has continued to be a useful procedure over the past 25 years.

After preoperation assessment including subjective complains (snoring, sleep apnea, nasal blockage, mouth breathing, and daytime fatigue) and objective assessment (BMI, ENT examination, PSG, and computed tomography [CT] scan), all 12 patients went through bilateral endoscopic total ethmoidectomy, bilateral endoscopic middle meatal antrostomy
with removal of maxillary sinus tissue, bilateral submucous resection of the inferior turbinates, and bilateral outfracturing of the inferior turbinates.
27) The surgical management involves complete removal of the polyp (both antral and nasal parts) and wide middle meatal antrostomy
, along with correction of any predisposing anatomic variants.
Anatomy of maxillary ostia should be well understood by the endoscopic sinus surgeons in order to perform the middle meatus antrostomy
The conference was preceded by courses and workshops on Skull Base Surgery: From open to endoscopic- the transition and evolution, Nasal/sinus anatomy for the neurosurgeons- the intranasal landmarks, antrostomy
, ethmoidectomy, Endoscopic approaches to the pituitary and the skull base-Tips and the techniques, anatomical dissection besides indications and limitations of endoscopic approach to anterior skull base.
Following discussion by the multi-disciplinary team, a working diagnosis of sinonasal myxoma was agreed upon with recommendation for a left Caldwell-Luc antrostomy
, leading to extensive excision of the mass.
Patients requiring other procedures like cautery, submucosal diathermy, turbinectomy and middle meatal antrostomy
With diagnosis of refractory chronic sinusitis to antibiotic treatment, a left maxillary sinus antrostomy
was performed and from the material obtained a request was made for bacteria, mycobacteria, and fungus cultures, as well as a histopathological study.
