Nasal polyps are benign lesions associated with mucosal inflammation of the nasal cavity and paranasal sinuses. Choanal polyps most commonly originate from the maxillary sinus. Fronto-choanal polyps are rare forms of choanal polyps, may occlude the choana and it should be kept in mind in the etiology of nasal obstruction. Treatment is total surgical excision. A 50-year-old patient presented to our outpatient clinic with symptoms of chronic rhinosinusitis that had persisted for 10 years. Endoscopic examination revealed that he had adenoid hypertrophy and a choanal polyp originating from frontal recess. The frontochoanal polyp was excised on endoscopic surgery and an adenoidectomy operation was performed simultaneously. Fronto-choanal polyps are very rare and there is lack of enough information in the literature. We aimed to contribute to the literature that in some cases operated on as antrochoanal polyp, the polyp may originate from regions other than the maxillary antrum. It can be recommended that isolated polyps extending to the choanae should be named according to their region of origin and the surgery should extend to this area.

Objectives The aim of our study to contribute to the field of morphometrics by including measurements of the SAC and SAF and their distances from surrounding structures, particularly for surgeons involved in retrosigmoid approach for internal acoustic meatus tumor surgery and cerebellopontine angle surgery. Although there is limited information in the literature regarding the role of the subarcuate fossa (SAF) and subarcuate canal (SAC), it has been suggested that the SAC may be a potential pathway for infection from the middle ear to the posterior cranial fossa, and cerebellar abscesses may have this origin. Methods For the images of our study, computerized tomography images of 118 individuals (59 females and 59 males) between the ages of 18–65 who applied to xxxx Health Group. Results The width of the cranial opening of the subarcuate canal was determined as 44 ± 0.54 mm, width of the labyrinth opening of the subarcuate canal was determined as 60 ± 0.42 mm, Length of the subarcuate canal was determined as 8.79 ± 2.31 mm, width of the subarcuate canal was determined as 5.54 ± 1.75 mm, and depth of subarcuate fossa was determined as 1.67 ± 0.69 mm. The distance of the cranial opening of the subarcuate canal to the superior semicircular canal (SSC–SAC/C) was measured as 5.33 ± 1.81 mm, The distance of the labyrinth opening of the subarcuate canal to the superior semicircular canal (SSC–SAC/L) was measured as 3.90 ± .98 mm, length of the petrous part of the temporal bone medial to the anterior semicircular canal measured from the apex to the SSCD (PLM) was measured as 33.56 ± 0.42 mm. No statistically significant differences were found between the right and left sides. Conclusions The morphometric measurements obtained in this study can provide useful information for neurosurgeons, neurotologist and otolaryngologists involved in retrosigmoid approach for internal acoustic meatus tumor surgery and cerebellopontine angle surgery, and for patients undergoing cochlear implant planning with a retrofacial approach.

Purpose: Conventional cold curettage adenoidectomy(CCA) is the most used method for Adenoidectomy. With the advances in surgical instruments, endoscopy assisted less invasive techniques are coming into use. Herein we compared CCA with endoscopic microdebrider adenoidectomy(EMA) in terms of safety and recurrence.Methods: Patients who underwent adenoidectomy in our clinic between 2009-2021 years were included into the study. Study performed retrospectively. Patients operated with CCA accepted as GroupA and EMA as GroupB. Two groups compared for the recurrence rate and post-operative complications. Results: We studied 833 children aged between 3-12 years (mean 4,2 years old), had adenoidectomy, including 482 male(57.86%) and 351 female(42.14%). There were 473 patients in GroupA, and 360 patients in GroupB. Seventeen patients(%3.59) in GroupA had reoperation for the recurrence of adenoid tissue. There was no recurrence in GroupB. Residual tissue, recurrent hypertrophy, and postoperative otitis media rates were higher in GroupA, and this was statistically significant(p0.05). Although hypernasality rate at second week was slightly higher in GroupB, this was not statistically significant(p>0.05), and in further period it resolved in all patients. No major complications were reported. Conclusion: Our study indicates that EMA is a safer technique than CCA, and prominent postoperative complications like residual adenoid tissue, recurrent adenoid hypertrophy, and postoperative otitis media with effusion rates are lower.

‘Lateral meatal Fossa’ and ‘lateral meatal tissue pad’, new anatomic landmarks on the lateral part of external bony ear canal posterosuperiorly just beneath the suprameatal spine which when identified and taken into consideration, may have a definite advantage in retroauricular approach to middle ear surgery. The bony external ear canal also may be divided in two parts as lateral and medial bony external ear canal. Therewithal tympanomeatal flap covering canal may be denominated to lateral tympanomeatal flap and medial tympanomeatal flap.
