Binasal hemianopia caused by pneumosinus dilatans of the sphenoid sinuses

Bitemporal hemianopia is a significant pathological hallmark of a pituitary lesion; however, binasal hemianopia is rarely reported, except for its known association with other ocular diseases rather than with brain lesions. We report a 24-year-old male with binasal hemianopia caused by pneumosinus dilatans of the sphenoid sinuses.

Bilateral Pneumosinus Dilatans of the Maxillary Sinuses with Facial Pain / 대한이비인후과학회지

Pneumosinus dilatans is a rare disease in which 1 or more paranasal sinuses are dilated without functional alteration. The frontal sinus is the most commonly affected site, with involvement of the maxillary sinus being rare. A 25-year-old man had complained of facial pain and headache of frontal area. These symptoms were aggravated after nose blowing. A computed tomographic scan showed a hyperaeration of both maxillary sinus and frontal sinus. We treated the condition by endoscopic sinus surgery (middle meatal antrostomy, both). Just after operation, facial pain and headache of frontal sinus have subsided. No recurrence was detected. In this article, the authors present surgical options for the treatment of pneumosinus dilatans of the maxillary sinus, including a review of the literature.

Spontaneous Pneumocephalus Associated with Pneumosinus Dilatans

The majority of cases of pneumocephalus are secondary to trauma or medical intervention. Spontaneous, non-traumatic pneumocephalus is an uncommon condition. Most cases of spontaneous pneumocephalus require surgery. However, if there is no evidence of infection or cerebrospinal fluid leak, bed rest and follow-up imaging is an alternative treatment. Herein, we report a 31-year-old man with spontaneous pneumocephalus associated with pneumosinus dilatans.

2 Cases of Pneumosinus Dilatans

Pneumosinus Dilatans consists of an abnormal dilatation of the paranasal sinuses which contain air only and lined by normal mucosa. It is a rare condition, the etiology of which is unclear. A 16 year old male complained frontal bossing which developed slowly. Simple X-ray and CT showed abnormal distension of frontal sinus. Another 19 year old male complained slowly growing left cheek mass. Simple X-ray and CT showed abnormal distension of anteromedial wall of maxillary sinus. In view of the cosmetic appearance, operations were performed. Distended sinuses walls were removed and reconstructed using Medpore(R). I report 2 cases of pneumosinus dilatans which developed in frontal and maxillary sinuses and the literature reviewed.

A Case Report of Operative Treatment for Pneumosinus Dilatans of Maxillary Sinus

PURPOSE: Pnumosinus dilatans is a rare disease that one or more of the paranasal sinuses are dilatated without functional alteration. The most frequently involved sites are frontal and sphenoid sinus. Facial asymmetric contour is the most common signs and nasal obstruction and pain may be combined. The purpose of reconstruction of pneumosinus dilatans is two-fold, to re-establish a permanent pressure equilibrium of sinus and to correct the possible facial deformities. METHODS: We present a case of a 24-year-old female with a 7-year history of protrusion of right malar region. Plane radiography and computed tomography detailed an abnormal expansion of the right maxillary sinus without thinning of bony wall, leading to diagnosis of maxillary pneumosinus dilatans. Surgical decompression and maxilloplasty were achieved by ostectomy of anterior wall of maxillary sinus and repositioning of removed bony fragment with miniplate. RESULTS: Post operative course was uneventful without complication and malar height became symmetric by physical and radiologic examination. CONCLUSION: We corrected successfully pneumosinus dilatans of maxillary sinus by surgical decompression and maxilloplasty. For this case, we reviewed literature related to this topic.

Surgical Correction of Pneumosinus Dilatans of the Frontal Sinus

Pneumosinus dilatans is a rare condition of paranasal sinus, which is most commonly found in males of the age between 20 to 40. That is defined hypersinus as the enlargement of a paranasal sinus beyond the upper limits of normal. The deformity is caused by an abnormal enlargement of the paranasal sinus by hyperpneumatization. A valve mechanism raising the pressure inside the sinus is regarded to be responsible for this condition. A preoperative computed tomography scan is used to illustrate the anatomical condition and possible etiologic mechanisms and the most commonly affected sinus is the frontal sinus. Numerous methods have been suggested to repair the anatomical deformities of frontal sinus and we represent a method of correction for pneumosinus dilatans, too. We approached the frontal sinus by using a bicoronal incision and exposed total frontal sinus to remove total outer wall at one piece. We remodeled outer wall of fontal sinus by one piece and fixed with absorbable plates and screws. Ten months after the successful operation, the patient was satisfied with a good cosmetic result without recurrence. The latest, this comsmetic surgery is attractive and we wanted to improve frontal sinus bossing commonly, but it is not usual. Here, we present a case of pneumosinus dilatans of the frontal sinus of the repair method.
